    TELICIA OWENS, Appellant
    V.
    KRISTA G. HANDYSIDE, M.D., SAMUEL J. PRATER, M.D., KENNETH
    A. TOTZ, D.O., FACEP, AND MEMORIAL HERMANN HOSPITAL
    SYSTEM D/B/A MEMORIAL HERMANN – TEXAS MEDICAL CENTER,
    Appellees
    On Appeal from the 152nd District Court
    Harris County, Texas
    Trial Court Case No. 2012-07534
    OPINION
    Appellant, Telicia Owens, challenges the trial court’s dismissal of her health
    care liability claims 1 against appellees, Krista G. Handyside, M.D., Samuel J.
    Prater, M.D., Kenneth A. Totz, D.O., FACEP, 2 and Memorial Hermann Hospital
    System, doing business as Memorial Hermann – Texas Medical Center (“Memorial
    Hermann”).3     In three issues, Owens contends that the trial court erred in
    dismissing her claims on the grounds that she failed to timely serve her medical
    expert report on appellees, her medical expert is not qualified to opine on the
    standard of care of hospital emergency room doctors, and her report insufficiently
    addresses the issues of standard of care and causation. 4
    We reverse and remand.

    Owens sued “Kenneth A. Totz, M.D.” We note that in his answer, Dr. Totz
    identifies himself as “Kenneth A. Totz, D.O., FACEP,” as does the trial court in its
    dismissal order. Our style of the case is in accord with the trial court’s dismissal
    order. See Strobel v. Marlow, 
    341 S.W.3d 470
    , 471 n.1 (Tex. App.—Dallas 2011,
    no pet.).
    3
    Owens sued “Memorial Hermann Healthcare System d/b/a Memorial Hermann
    Hospital.” In its answer, Memorial Hermann stated that it was incorrectly named.
    In its dismissal order, the trial court identifies Memorial Hermann as “Memorial
    Hermann Hospital System d/b/a Memorial Hermann – Texas Medical Center.”
    Our style of the case is in accord with the trial court’s dismissal order. See 
    id.

    See TEX. CIV. PRAC. & REM. CODE ANN. § 74.351(a) (Vernon Supp. 2014)
    (governing medical expert reports).           In 2013, the legislature amended
    section 74.351 of the Texas Medical Liability Act. See Act of May 26, 2013, 83rd
    Leg. R.S., ch. 870, § 2, 2013 TEX. SESS. LAW SERV. 2220, 2220. The new
    provision applies to all suits filed after September 1, 2013. Because Owens filed
    her original petition in 2010, we apply the former version of section 74.351 to her
    claims. See Act of May 18, 2005, 79th Leg., R.S., ch. 635, § 1, 2005 TEX. GEN.
    LAWS 1590, 1590 (amended 2013) (current version at TEX. CIV. PRAC. & REM.
    CODE ANN. § 74.351).
    2
    Background
    In her petition, Owens alleges that on February 6, 2010, she went to the
    “Emergency Department at Memorial Hermann,” complaining of a “severe
    headache.” She was diagnosed with a “migraine, tension headache, and headache
    associated with sinuses[,]” and “[n]o diagnostic testing was done to rule out any
    internal problems.” On February 10, 2010, Owens “returned to the Emergency
    Department at Memorial Hermann,” complaining of “the same persisting
    symptoms.” Dr. Handyside diagnosed her as suffering from a “headache and
    sinitus.” Again, no diagnostic testing was performed. On February 21, 2010,
    Owens “returned again to the [E]mergency [D]epartment at Memorial Hermann,”
    complaining of a “headache and blurry vision.” Drs. Prater and Totz treated her,
    and they diagnosed her as suffering from a “headache.” Again, no diagnostic
    testing was performed.
    Subsequently, on February 24, 2010, Owens went to “Methodist Hospital for
    assessment of the same symptoms that she complained of at Memorial Hermann.”
    Doctors administered a “CT scan,” which showed that she was suffering from a
    “head bleed.” Methodist admitted Owens into its Intensive Care Unit, and it
    discharged her on March 3, 2010.
    On April 22, 2010, Owens went to “Ben Taub General Hospital[,]
    complaining of sudden blindness, which resulted in [the] placement of a lumbar
    3
    shunt.” On May 14, 2010, she returned to Ben Taub, “complaining of sutures
    coming out, shunt leak[age], blurred vision, and [a] headache.” Ben Taub admitted
    Owens for evaluation and subsequently discharged her. On May 17, 2010, Owens
    again returned to Ben Taub, “complaining of [a] headache, chest pain, and neck
    stiffness.” Her shunt was infected, and it was removed. Owens was “found to
    have been infected with MRSA—Methicillin Resistant Staphyloccus Auereus.”
    Owens further alleges that she sustained “permanent damage to her optic
    nerve and is completely blind in both of her eyes. She has continuous subsequent
    damage and pain.” However, Owens does not specify in her petition the medical
    cause or reason for her loss of vision and residual “damage and pain.”
    Owens brings health care liability claims against Drs. Handyside, Prater, and
    Totz for negligence and gross negligence, specifically alleging that they:
    •      Failed to obtain an accurate assessment of Owens;
    •      Failed to notice signs and symptoms of “Cerebral Venous Sinus
    Thrombosis” (“CVST”);
    •      Failed to accurately and timely diagnose Owens;
    •      Failed to consider possible explanations and respond to severe
    headaches and blurry vision;
    •      Failed to order appropriate radiological studies;
    •      Failed to make a medical diagnosis based on Owens’s clinical
    condition;
    4
    •     Failed to consult with a neurologist or other specialist while Owens
    was in the emergency department;
    •     Failed to develop and carry out a proper treatment plan for Owens;
    •     Failed to admit Owens to “Neurological ICU”;
    •     Failed to order thrombolytic medication necessary to attempt to
    dissolve thrombosis;
    •     Failed to adhere to “Federal Laws regarding EMTALA regarding
    emergently treating a patient” regardless of her inability to pay;
    •     Failed to order appropriate diagnostic tests and treatments even once
    “cerebral venous sinus thrombosis” was suspected as a possible cause
    of Owens’s symptoms; and
    •     Negligently managed a patient with CVST.
    Owens likewise brings direct-liability claims for negligence and gross
    negligence against Memorial Hermann, specifically alleging that it:
    • Failed to select and retain only competent physicians and staff;
    • Failed to properly supervise the health care providers who treated Owens;
    • Failed to enforce or have in place policies, protocols, by-laws, rules and
    regulations regarding proper diagnosis and treatment of Owens’s medical
    condition;
    • Failed to enforce or have in place policies and protocols, with regard to
    consulting specialty physicians;
    • Failed to have a medical director or chief of staff in place that properly
    supervised physicians and staff; and
    • Failed to abide by recommendations and requirements of healthcare
    certifying organizations.
    5
    “As a result of the above-noted acts of negligence,” Owens asserts that
    appellees “directly and proximately caused” her “injuries, losses, and damages.”
    She also alleges that Memorial Hermann is vicariously liable for the negligent
    “acts and/or omissions” of its staff, including, among others, Drs. Handyside,
    Prater, and Totz.
    To support her claims, Owens, on or about May 29, 2012, filed and served
    upon appellees a medical expert report authored by Brian C. Richardson, M.D.
    Appellees objected to Dr. Richardson’s report on several grounds, including that
    Owens did not timely serve it; it failed to sufficiently address the elements of
    standard of care, breach of the standard, and causation; and Richardson, a
    neurologist, is not qualified to opine on the standard of care of hospital emergency
    room doctors or causation. Dr. Totz filed his objection to the sufficiency of
    Richardson’s report on June 19, 2012.
    Owens, on July 17, 2012, filed her response to the objections of appellees,
    attaching United States Postal Service (“USPS”) certified mail receipts and “green
    cards,” which evidence service of Dr. Richardson’s expert report on appellees by
    certified mail. However, the signature line on the green card for Dr. Totz does not
    contain a signature, and both the USPS certified mail receipt and green card
    pertaining to him show the wrong zip code for his home address. On August 15,
    2012, Totz filed a “Supplemental Objection” to Richardson’s expert report,
    6
    attaching to it his affidavit and the affidavit of his attorney, Charles B. Holm. Totz
    testified that he had “never received a copy of Dr. Richardson’s Expert Report via
    certified mail, return receipt requested at [his] personal residence” and he “never
    executed” the green card attached to Owens’s response. Although Holm testified
    that he had “never received a copy of Dr. Richardson’s Expert Report from the
    Plaintiff or her attorney on or before June 6, 2012,” and neither had anyone at his
    law firm, he conceded that he had “obtained a copy of Dr. Richardson’s Expert
    Report though alternative means.”       Owens did not file a response to Totz’s
    supplemental objection.
    After a hearing, the trial court sustained Dr. Totz’s specific objection that
    Owens had failed to timely serve him with Dr. Richardson’s expert report, and it
    dismissed Owens’s claims against him.          It also sustained the objections of
    Memorial Hermann and Drs. Handyside and Prater as to the adequacy of
    Richardson’s expert report, but it allowed Owens thirty days to file and serve upon
    them an amended report.
    Owens then filed and served Dr. Richardson’s amended medical expert
    report on Memorial Hermann and Drs. Handyside and Prater. In Richardson’s
    amended report, he notes that he is a “physician in private practice,” is “licensed to
    practice medicine in the State of California,” and is “board certified in adult
    neurology and vascular neurology.” Richardson further states:
    7
    I have knowledge of accepted and established standards of medical
    care for the patient[’]s diagnosis that is involved in the claim. I
    obtained this knowledge via my residency and fellowship training as
    well as via experience[] gained in the practice of neurology for over
    19 years.
    ....
    As a neurologist board certified in general adult neurology and
    vascular neurology[,] I have seen, diagnosed and managed many
    patients with dural sinus thrombosis. I have also seen, diagnosed and
    managed patients with idiopathic intracranial hypertension (formerly
    referred to as pseudotumor cerebri or benign intracranial
    hypertension). As such[,] I am familiar with the standard of care for
    the diagnosis, care and treatment of both dural sinus thrombosis and
    idiopathic intracranial hypertension.
    Richardson also explains that he reviewed Owens’s medical records prior to
    forming his opinions.
    Dr. Richardson notes that the applicable standard of care for Dr. Handyside,
    concerning a patient complaining of,
    a severe headache of one week duration . . . without a prior history of
    recurrent headaches would include cerebral imaging[,] such as [a] CT
    or preferably [a] brain MRI. [A] [l]umbar puncture should have been
    performed as well. A neurology consultation should have been
    obtained. It should have been clear to the examining physician that
    the patient had a potentially serious neurological condition. The
    differential diagnosis should have included dural sinus thrombosis.
    The standard of care would also have included admission or urgent
    appropriate outpatient follow-up . . . .
    In regard to the applicable standard of care for Dr. Prater, Richardson states the
    following:
    8
    [Owens was diagnosed with] rule out cavernous sinus thrombosis, rule
    out meningoenchephalitis. . . . These are two very serious diagnoses
    that should have prompted admission to the hospital and [an] urgent
    neurological consultation. At the very least[,] neurodiagnostic
    studies[,] such as [a] lumbar puncture, [a brain CT], or [a] brain
    MRI[,] should have been performed. The standard of care for
    evaluating patients with possible meningitis is to perform a lumbar
    puncture right away. Neurological consultation and neuroimaging[,]
    such as [a brain CT scan] or [a] brain MRI[,] should be done promptly
    when cavernous sinus thrombosis is being entertained as a diagnosis.
    Patients should be admitted to the hospital rather than discharged
    when life-threatening diagnoses such as these are considered. . . . As
    stated above, cerebral imagining, [a] CT or preferably [a] brain
    MRI[,] should have been done. A lumbar puncture should have been
    performed given the diagnoses of the examining physicians.
    Finally, regarding the applicable standard of care for Memorial Hermann,
    Richardson notes that it “should have had protocols for evaluation, consultation,
    admission and follow-up that resulted in adequate care of patients with conditions
    such as dural sinus thrombosis and idiopathic intracranial hypertension.        The
    failure to have in place and abide by such protocols was a bre[a]ch in the standard
    of care.”
    In regard to causation, Dr. Richardson opines that,
    If Dr. . . . Handyside had performed cerebral imaging[,] such as [a]
    CT or preferably [an] MRI, performed [a] lumbar puncture or
    obtained [a] neurological consultation it is medically probable
    that . . . Owens would have had her condition diagnosed and treated in
    a timelier manner. Early treatment of dural sinus thrombosis reduces
    the likelihood of complications[,] such as idiopathic intracranial
    hypertension. Thus[,] her vision would have most likely been spared
    and she would not have lost vision in the right and left eyes. Severe
    loss of vision is a preventable complication of dural sinus thrombosis.
    9
    If Dr[]. . . . Prater performed [a] lumbar puncture, ordered cerebral
    imaging[,] such as [a] head CT and preferably [an] MRI, admitted
    [Owens to the hospital] and/or obtained [a] neurological
    consultation, . . . Owens would have likely had a more timely
    diagnosis, earlier treatment and her vision would medically probably
    have been saved. If . . . Prater had not prescribed dexamethazone
    for . . . Owens[,] it is medically probable that her condition would not
    have been exacerbated. It is possible she would have not progressed
    to . . . have [a] loss of vision.
    ....
    Memorial Herman[n] . . . failed to have and/or implement adequate
    protocols for evaluation, consultation, admission and follow-up that
    resulted in adequate care of this patient with dural sinus thrombosis
    and idiopathic intracranial hypertension. The failure to have in place
    and abide by such protocols was a bre[a]ch in the standard of care that
    was a proximate cause of . . . Owens subsequently developing
    blindness in the right and left eyes.
    (Footnote omitted.) Richardson further opines that:
    . . . Owens developed dural sinus thrombosis . . . . This is an
    uncommon, but well known condition that is treatable with
    anticoagulant medications. There was a significant delay in the
    diagnosis of this condition. This delay resulted in the development of
    a complication, severe vision loss due to idiopathic intracranial
    hypertension. Severe vision loss due to intracranial complication can
    generally be easily treated with medication if it is diagnosed early.
    And he explains that:     “Untreated dural sinus thrombosis is well known to
    potentially cause idiopathic intracranial hypertension.      Idiopathic intracranial
    hypertension may progress to blindness if untreated. It is medically probable that
    early diagnosis would have prevented [Owens’s] later development of vision loss.”
    (Footnote omitted.)
    10
    Memorial Hermann and Drs. Handyside and Prater objected to Dr.
    Richardson’s amended medical expert report and moved to dismiss Owens’s
    claims against them on the grounds that Richardson is not qualified to opine on the
    standard of care for hospital emergency room doctors and his report insufficiently
    addresses the issues of standard of care and causation. Drs. Handyside and Prater
    also reasserted their untimeliness objections. Without stating its reasons, the trial
    court granted the motions of Memorial Hermann and Drs. Handyside and Prater to
    dismiss Owens’s health care liability claims.
    Standard of Review
    We review a trial court’s decision on a motion to dismiss a health care
    liability claim for an abuse of discretion. See Am. Transitional Care Ctrs. of Tex.,
    Inc. v. Palacios, 
    46 S.W.3d 873
    , 875 (Tex. 2001); Gray v. CHCA Bayshore L.P.,
    
    189 S.W.3d 855
    , 858 (Tex. App.—Houston [1st Dist.] 2006, no pet.). A trial court
    abuses its discretion if it acts in an arbitrary or unreasonable manner without
    reference to guiding rules or principles. Jelinek v. Casas, 
    328 S.W.3d 526
    , 539
    (Tex. 2010). When reviewing matters committed to a trial court’s discretion, we
    may not substitute our own judgment for that of the trial court. Bowie Mem’l
    Hosp. v. Wright, 
    79 S.W.3d 48
    , 52 (Tex. 2002). A trial court does not abuse its
    discretion merely because it decides a discretionary matter differently than an
    11
    appellate court would in a similar circumstance. Harris Cnty. Hosp. Dist. v.
    Garrett, 
    232 S.W.3d 170
    , 176 (Tex. App.—Houston [1st Dist.] 2007, no pet.).
    Timeliness of Expert Report
    In her first issue, Owens argues that the trial court erred in dismissing her
    claims against Dr. Totz because he admitted in his objection, filed on June 19,
    2012, to Dr. Richardson’s report that he had timely received the report and he did
    not raise his timeliness objection “until August 15, 2012, more than two months
    after the expiration of the 120-day deadline.” Totz argues that Owens “failed to
    preserve her argument regarding [his] admission” of his timely receipt of
    Richardson’s expert report because she did not “ever raise [in the trial court] the
    argument that [he] admitted that he was timely served” with the report.
    The former version of section 74.351 of the Texas Civil Practice and
    Remedies Code, in effect at the time this suit was filed, provided that a health care
    liability claimant shall, “not later than the 120th day after the date the original
    petition [is] filed, serve on each party or the party’s attorney one or more expert
    reports.”5 See Act of May 18, 2005, 79th Leg., R.S., ch. 635, § 1, 2005 TEX. GEN.
    LAWS 1590, 1590 (amended 2013) (current version at TEX. CIV. PRAC. & REM.
    CODE ANN. § 74.351(a) (Vernon Supp. 2014)). It further provided that if an expert
    5
    The legislature’s 2013 amendment to section 74.351(a) requires each health care
    liability claimant to serve an expert report “not later than the 120th day after each
    defendant’s original answer is filed.” See TEX. CIV. PRAC. & REM. CODE ANN.
    § 74.351(a) (emphasis added).
    12
    report is not timely served, the affected health care provider may move to dismiss a
    claim asserted against it, and the court must dismiss the claim with prejudice. TEX.
    CIV. PRAC. & REM. CODE ANN. § 74.351(b); Heriberto Sedeno, P.A. v. Mijares,
    
    333 S.W.3d 815
    , 818, 822–23 (Tex. App.—Houston [1st Dist.] 2010, no pet.). A
    health care provider may waive its right to complain about the adequacy of an
    expert report by failing to challenge the report’s adequacy within twenty-one days
    of service of the report. See Act of May 18, 2005, 79th Leg., R.S., ch. 635, § 1,
    2005 TEX. GEN. LAWS 1590, 1590 (amended 2013) (current version at TEX. CIV.
    PRAC. & REM. CODE ANN. § 74.351(a)); Ogletree v. Matthews, 
    262 S.W.3d 316
    ,
    321–22 (Tex. 2007). However, there is no deadline to file a motion to dismiss for
    failure to timely serve a chapter 74 expert report. Jernigan v. Langley, 
    111 S.W.3d 153
    , 156 (Tex. 2003); Heriberto, 
    333 S.W.3d at
    823–24. In other words, a health
    care provider does not waive its right to dismissal of an untimely expert report by
    waiting to file its motion to dismiss. See Jernigan, 111 S.W.3d at 156–57 (waiting
    more than 600 days to move for dismissal). Accordingly, we hold that Dr. Totz
    did not waive his right to complain about the timeliness of Owens’s service of Dr.
    Richardson’s report.
    Regarding Dr. Totz’s argument that Owens “failed to preserve her argument
    regarding [his] admission” of his timely receipt of Dr. Richardson’s expert report,
    we note that in reviewing a trial court’s judgment, we may only consider what was
    13
    before the trial court at the time it made its decision. San Jacinto Methodist Hosp.
    v. Carr, No. 01-07-00655-CV, 
    2008 WL 2186473
    , at *3 (Tex. App.—Houston [1st
    Dist.] May 22, 2008, no pet.) (mem. op.); Hansen v. Starr, 
    123 S.W.3d 13
    , 18
    (Tex. App.—Dallas 2003, pet. denied); see also TEX. R. APP. P. 33.1(a). As Totz
    noted, Owens did not respond to his supplemental objection, in which he raised the
    issue of the timeliness of Owens’s service of Richardson’s report. And, thus, she
    did not argue to the trial court that Totz had admitted that he had timely received
    Richardson’s report. However, it was not necessary for her to make this assertion
    in her response.
    Dr. Totz’s attorney, Charles B. Holm, in his affidavit attached to Totz’s
    August 15, 2012 “Supplemental Objection” to Dr. Richardson’s expert report,
    conceded that he had “obtained a copy of Dr. Richardson’s Expert Report though
    alternative means.”    His affidavit testimony does not contain an affirmative
    statement that he did not timely receive a copy of the report. Rather, he merely
    states that he “never received a copy of Dr. Richardson’s Expert Report from the
    Plaintiff or her attorney on or before June 6, 2012” and neither had anyone at his
    law firm.    (Emphasis added.)      Likewise, Totz, in his affidavit, does not
    affirmatively state that he did not receive a copy of the report. Rather, he states
    that he “never received a copy of Dr. Richardson’s Expert Report via certified
    14
    mail, return receipt requested at my personal residence” and had “never executed”
    the green card attached to Owens’s response to his objection. (Emphasis added.)
    Importantly, neither Dr. Totz nor his attorney, in their affidavit testimony,
    denies having timely received a copy of Dr. Richardson’s report. And the trial
    court, at the time it made its decision to dismiss Owens’s claims against Totz, had
    before it Holm’s testimony that he had “obtained a copy of Dr. Richardson’s
    Expert Report though alternative means.” Accordingly, we hold that Owens did
    not fail to preserve her argument regarding Totz’s admission that he had timely
    received a copy of Richardson’s expert report.6
    In regard to the merits of Owens’s first issue, Dr. Totz argues that the trial
    court did not err in dismissing Owens’s claims against him because, under a proper
    construction of section 74.351 of the Civil Practice and Remedies Code, she had
    6
    Dr. Totz also argues that Owens waived her “appellate issues” as to him because
    she did not reference in her notice of appeal the September 6, 2012 order granting
    Totz’s motion to dismiss or serve Totz with certain documents. As explained in
    our April 29, 2014 order, although Owens did not list the trial court’s September
    6, 2012 order granting Totz’s motion to dismiss in her notice of appeal, “the rules
    do not require [her] to list in the notice of appeal every interlocutory ruling that
    [she] may wish to appeal.” See Ostrovitz & Gwinn, LLC v. First Specialty Ins.
    Co., 
    393 S.W.3d 379
    , 386 (Tex. App.—Dallas 2012, no pet.). Further, we note
    that “our decisions construing the appellate rules have not favored disposing of
    appeals on harmless procedural defects.” See Sweed v. Nye, 
    323 S.W.3d 873
    , 875
    (Tex. 2010); see also Higgins v. Randall Cnty. Sheriff’s Office, 
    257 S.W.3d 684
    ,
    688 (Tex. 2008) (“[W]e have long interpreted the Rules of Appellate Procedure
    liberally in favor of preserving appellate rights.”); Tex. S. Univ. v. Araserve
    Campus Dining Servs. of Tex., Inc., 
    981 S.W.2d 929
    , 935 n.12 (Tex. App.—
    Houston [1st Dist.] 1998, pet. denied) (docketing statement does not limit or waive
    party’s appellate arguments).
    15
    not timely served Dr. Richardson’s expert report upon him, even though he had
    received it and was able to timely object to its sufficiency, as she had not served
    him by certified mail or in person.     However, the Texas Supreme Court has
    concluded otherwise, on similar facts. See Zanchi v. Lane, 
    408 S.W.3d 373
     (Tex.
    2013). In Zanchi, the court specifically held:
    [W]e conclude, that, under section 74.351(a) of the TMLA, a
    physician or health care provider against whom [a health care liability
    claim] is asserted is a “party” who may be served with an expert
    report regardless of whether he has been served with process. We
    further hold that an expert report need not be “served” in compliance
    with the formal requirements of Rule 106 [governing citation and
    service of process] that apply specifically to service of citation.

    Here, the record reveals that Owens filed her petition on February 7, 2012,
    naming Dr. Totz as a defendant. She then filed and served Dr. Richardson’s initial
    expert report on the defendants on or about May 29, 2012. Although the USPS
    certified mail receipt and green card show that Owens used the wrong zip code in
    mailing the report to Totz and he was not served with the expert report in person or
    by certified mail, Totz and his attorney did in fact timely obtain a copy of the
    report “though alternative means.” Accordingly, we hold that the trial court erred
    in granting Totz’s motion to dismiss Owens’s claims against him on the ground
    16
    that she had failed to timely serve him with Richardson’s report. We sustain
    Owens’s first issue.7
    Sufficiency of Expert Report
    In her second issue, Owens argues that the trial court erred in dismissing her
    claims against Memorial Hermann and Drs. Handyside and Prater because “Dr.
    Richardson is fully qualified . . . to offer opinions in this case” and he adequately
    addresses the elements of standard of care and causation in his report.8
    As noted above, a health care liability claimant must timely provide each
    defendant health care provider with an expert report. See TEX. CIV. PRAC. & REM.
    CODE ANN. § 74.351; Gray, 
    189 S.W.3d at 858
    . The report must provide a “fair
    summary” of the expert’s opinions as of the date of the report regarding the
    applicable standards of care, the manner in which the care rendered by the health
    care provider failed to meet the standard, and the causal relationship between that
    7
    In her brief, Owens also asserts that she timely served Dr. Richardson’s report on
    Memorial Hermann and Drs. Handyside and Prater. In response, Drs. Handyside
    and Prater state that they “no longer object to the timeliness of the expert report of
    Dr. Richardson.” Similarly, in its brief, Memorial Hermann states, “[o]n or about
    May 30, 2012, [Owens] timely served on [Memorial Hermann] an initial expert
    report of Brian C. Richardson, M.D.” Accordingly, we do not address this portion
    of Owens’s first issue.
    8
    Owens also asserts that Dr. Richardson’s expert report adequately addresses the
    element of breach of the standard of care. However, neither Memorial Hermann
    nor Drs. Handyside or Prater objected to Richardson’s report on this ground.
    Further, to the extent that Owens asserts that the report is sufficient in regard to
    Dr. Totz, we note that the trial court dismissed Owens’s claims against Totz on the
    ground that she had not timely served him with the report. Accordingly, we do not
    address these portions of Owens’s second issue.

    failure and the injury, harm, or damages claimed. TEX. CIV. PRAC. & REM. CODE
    ANN. § 74.351(r)(6).
    If a defendant health care provider files a motion to dismiss, challenging the
    adequacy of a claimant’s expert report, a trial court must grant the motion if it
    appears, after a hearing, that the report does not represent an objective good faith
    effort to comply with the definition of an expert report or is not sufficiently
    specific to provide a basis for the trial court to conclude that the claims have merit.
    Id. § 74.351(l); Scoresby v. Santillan, 
    346 S.W.3d 546
    , 555–56 (Tex. 2011). In
    setting out the expert’s opinions, the report must provide enough information to
    fulfill two purposes: (1) it must inform the defendant of the specific conduct that
    the plaintiff has called into question, and (2) it must provide a basis for the trial
    court to conclude that the claims have merit. Scoresby, 346 S.W.3d at 556.
    Dr. Richardson’s Qualifications
    Owens first argues that the trial court, to the extent that it granted Drs.
    Handyside’s and Prater’s motions to dismiss her claims on the ground that Dr.
    Richardson is not qualified to address the standard of care, erred because
    “Richardson is more than qualified to offer []his opinion.”9 Owens asserts that it
    does not matter that Richardson is “not an emergency room physician” and he is
    9
    Memorial Hermann did not challenge Dr. Richardson’s qualifications, and Drs.
    Handyside and Prater only assert that Richardson is not qualified to opine on the
    standard of care of hospital emergency room doctors.
    18
    “more than qualified to testify about dural sinus thrombosis and idiopathic
    intracranial hypertension, the conditions involved in [Owens’s] claim[s].”
    In order to qualify as an expert, an individual need not be a specialist in the
    particular area of the profession for which testimony is offered. Rittger v. Danos,
    
    332 S.W.3d 550
    , 558 (Tex. App.—Houston [1st Dist.] 2009, no pet.); Keo v. Vu,
    
    76 S.W.3d 725
    , 732 (Tex. App.—Houston [1st Dist.] 2002, pet. denied). However,
    merely being a doctor is insufficient. See Broders v. Heise, 
    924 S.W.2d 148
    , 152
    (Tex. 1996). Instead, “[a] medical [expert] who is not of the same school of
    medicine” must show that “he has practical knowledge of what is usually and
    customarily done by a practitioner under circumstances similar to those
    confronting the defendant.” Marling v. Maillard, 
    826 S.W.2d 735
    , 740 (Tex.
    App.—Houston [14th Dist.] 1992, no writ); see also Roberts v. Williamson, 
    111 S.W.3d 113
    , 121 (Tex. 2003) (doctor need not practice in particular field about
    which he opines if demonstrates knowledge, skill, experience, training, or
    education regarding specific issue before court qualifying him to give opinion on
    issue); Keo, 
    76 S.W.3d at 732
    . Analysis of an expert’s qualifications to opine as an
    expert on the subject matter of the report is limited to the four corners of the expert
    report or accompanying curriculum vitae. See Mem’l Hermann Healthcare Sys. v.
    Burrell, 
    230 S.W.3d 755
    , 758 (Tex. App.—Houston [14th Dist.] 2007, no pet.).
    19
    In order to opine on the standard of care, a person must (1) be “practicing
    medicine at the time such testimony is given or [have been] practicing medicine at
    the time the claim arose”; (2) have “knowledge of accepted standards of medical
    care for the diagnosis, care, or treatment of the illness, injury, or condition
    involved in the claim”; and (3) be “qualified on the basis of training or experience
    to offer an expert opinion regarding those accepted standards of medical care.”
    TEX. CIV. PRAC. & REM. CODE § 74.401(a) (Vernon 2011); see also id.
    § 74.351(r)(5)(A) (defining “expert,” with respect to person opining as to whether
    doctor departed from accepted standards of medical care, as one “qualified to
    testify under the requirements of Section 74.401”). To determine whether a person
    is qualified on the basis of training or experience, the court shall consider whether
    he “is board certified or has other substantial training or experience in an area of
    medical practice relevant to the claim” and “is actively practicing medicine in
    rendering medical care services relevant to the claim.” Id. § 74.401(c).
    Drs. Handyside and Prater assert that “[i]n order to satisfy the expert report
    requirement of [c]hapter 74, [Owens] needed to serve on [them] an expert report
    from someone who is qualified to offer opinions on the standard of care as it
    relates to the care they provided, as emergency physicians.” According to Drs.
    Handyside and Prater,
    Dr. Richardson’s curriculum vitae and reports solely list his
    occupation as a medical doctor specializing in neurology. He also
    20
    lists his clinical experience as that of being in private practice. He
    fails to show that he has any experience in emergency
    medicine . . . [and] fails to show that he has ever worked in an
    emergency department or worked closely with emergency physicians
    in treating and diagnosing patients . . . .
    (Internal citations omitted.)
    In his expert report, Dr. Richardson notes that he is a “physician in private
    practice,” “licensed to practice medicine in the State of California.” He has been
    in “private practice for 19 years” and is “board certified in adult neurology and
    vascular neurology by the American Board of Psychiatry and Neurology.” And
    Richardson further states:
    I have knowledge of accepted and established standards of medical
    care for the patient[’]s diagnosis that is involved in the claim. I
    obtained this knowledge via my residency and fellowship training as
    well as via experience[] gained in the practice of neurology for 19
    years.
    ....
    As a neurologist board certified in general adult neurology and
    vascular neurology[,] I have seen, diagnosed and managed many
    patients with dural sinus thrombosis. I have also seen, diagnosed and
    managed many patients with idiopathic intracranial hypertension
    (formerly referred to as pseudotumor cerebri or benign intracranial
    hypertension). As such[,] I am familiar with the standard of care for
    the diagnosis, care and treatment of both dural sinus thrombosis and
    indiopathic intracranial hypertension.
    Richardson’s curriculum vitae also reveals that he is a board certified
    neurologist in private practice, his fellowship focused on “[c]erebral blood flow
    and metabolism, and dementia,” he completed his residency in the field of
    21
    neurology, and has conducted research related to Alzheimer’s disease, vascular
    dementia, and strokes.
    In determining whether an expert is qualified, we must be careful not to
    draw expert qualifications “too narrowly.” Larson v. Downing, 
    197 S.W.3d 303
    ,
    305 (Tex. 2006); Adeyemi v. Guerrero, 
    329 S.W.3d 241
    , 247 (Tex. App.—Dallas
    2010, no pet.). The specific issue in this case is whether Drs. Handyside and Prater
    failed to timely and appropriately diagnose and treat Owens’s conditions.
    Dr. Richardson’s report shows that he has experience in treating and
    diagnosing patients with the conditions suffered by Owens, namely dural sinus
    thrombosis and idiopathic intracranial hypertension, which Drs. Handyside and
    Prater allegedly failed to diagnose and treat properly. And he is familiar with the
    standard of care applicable to doctors who care for patients with the same
    conditions with which Owens presented. See Tawa v. Gentry, No. 01-12-00407-
    CV, 
    2013 WL 1694869
    , at *7 (Tex. App.—Houston [1st Dist.] Apr. 18, 2013, no
    pet.) (mem. op.) (expert sufficiently qualified to opine on standard of care by
    “showing the injury involved was of the type [the expert] treated in his practice”
    (internal quotation marks omitted)); Hillery v. Kyle, 
    371 S.W.3d 482
    , 487 (Tex.
    App.—Houston [1st Dist.] 2012, no pet.) (concluding expert qualified, where
    expert stated familiarity “with the standards of care relevant to the condition
    involved in th[e] claim” and he had “diagnosed and treated, ‘patients with the
    22
    conditions similar to those experienced by’” plaintiff); Rittger, 
    332 S.W.3d at
    558–
    59 (noting focus not on defendant doctor’s area of expertise, but on condition
    involved in claim).
    Further, we note that the fact that Dr. Richardson is a neurologist, rather than
    an emergency room doctor, does not disqualify him as an expert in this case. See
    Rittger, 
    332 S.W.3d at 559
     (holding neurologist/professor of medicine qualified to
    opine on standard of care in case against emergency room doctor who failed to
    diagnose stroke in pregnant patient, explaining fact patient “was pregnant when
    she experienced her stroke or that she presented herself in an emergency room
    setting does not require that [expert] be an obstetrician or emergency room
    physician”); see also Hayes v. Carroll, 
    314 S.W.3d 494
    , 504–05 (Tex. App.—
    Austin 2010, no pet.) (holding doctor, board certified in general and vascular
    surgery, qualified to render opinion on standard of care applicable to emergency
    room specialist); Blan v. Ali, 
    7 S.W.3d 741
    , 746–47 (Tex. App.—Houston [14th
    Dist.] 1999, no pet.) (concluding neurologist qualified as expert on strokes,
    although defendant doctors were emergency room doctor and cardiologist).
    We conclude that Dr. Richardson has the knowledge, skill, experience,
    education, or training to render an opinion on the standard of care applicable to a
    doctor treating a patient with the conditions with which Owens presented.
    Accordingly, we hold that the trial court erred to the extent that it granted Drs.
    23
    Handyside’s and Prater’s motions to dismiss Owens’s claims on the ground that
    Richardson is not qualified to opine on the standard of care.
    Causation
    Owens next argues that the trial court, to the extent that it granted Drs.
    Handyside’s and Prater’s motions to dismiss her claims on the ground that Dr.
    Richardson did not adequately address the issue of causation, erred because
    Richardson, in his report, adequately addresses the issue of causation as it related
    to the doctors. 10
    An expert report must provide a “fair summary” of the expert’s opinions
    regarding the causal relationship between the failure of a health care provider to
    provide care in accord with the pertinent standard of care and the injury, harm, or
    damages claimed.      TEX. CIV. PRAC. & REM. CODE ANN. § 74.351(r)(6).               In
    assessing the sufficiency of a report, a trial court may not draw inferences; instead,
    it must exclusively rely upon the information contained within the four corners of
    the report. Wright, 79 S.W.3d at 52. “No particular words or formality are
    required [in the expert report], but bare conclusions will not suffice.” Scoresby,
    346 S.W.3d at 556 (footnotes omitted).
    10
    Because of our disposition of Owens’s final issue below, we do not address the
    portion of her second issue in which she argues that the trial court erred to the
    extent that it granted Memorial Hermann’s motion to dismiss her direct-liability
    claims against it on the ground that Dr. Richardson’s report did not adequately
    address the issues of standard of care and causation. See infra.
    24
    A causal relationship is established by proof that a negligent act or omission
    constituted a substantial factor in bringing about harm and, absent the act or
    omission, the harm would not have occurred. Costello v. Christus Santa Rosa
    Health Care Corp., 
    141 S.W.3d 245
    , 249 (Tex. App.—San Antonio 2004, no pet.).
    However, an expert report need not marshal all of the plaintiff’s proof necessary to
    establish causation at trial, and it need not anticipate or rebut all possible defensive
    theories that may ultimately be presented to the trial court. Wright, 79 S.W.3d at
    52; Fortner v. Hosp. of the Sw., LLP, 
    399 S.W.3d 373
    , 383 (Tex. App.—Dallas
    2013, no pet.). The expert must simply provide some basis that the defendant
    health care provider’s act or omission proximately caused injury. Wright, 79
    S.W.3d at 52–53. And the expert must explain the basis of his statements and link
    his conclusions to the facts. Id. at 52. A report that merely states an expert’s
    conclusions regarding causation is not sufficient. Id.; Palacios, 46 S.W.3d at 879.
    “[I]f an expert report contains only conclusions about [causation], the trial court
    has ‘no discretion but to conclude . . . that the report does not represent a good-
    faith effort’ to satisfy the statute.” Smith v. Wilson, 
    368 S.W.3d 574
    , 577 (Tex.
    App.—Austin 2012, no pet.) (quoting Palacios, 46 S.W.3d at 877, 880).
    In his expert report, Dr. Richardson explains:
    . . . Owens developed dural sinus thrombosis . . . . This is an
    uncommon, but well known condition that is treatable with
    anticoagulant medications. There was a significant delay in the
    diagnosis of this condition. This delay resulted in the development of
    25
    a complication, severe vision loss due to idiopathic intracranial
    hypertension. Severe vision loss due to intracranial complication can
    generally be easily treated with medication if it is diagnosed early. In
    the case of failure of medications, serial lumbar punctures can be done
    in some cases. Surgical procedures[,] such as lumboperitoneal shunt
    placement[,] are effective second line treatments. Optic nerve
    fenestration is an effective third level of treatment . . . .
    Further, Richardson notes: “Untreated dural sinus thrombosis is well known to
    potentially cause idiopathic intracranial hypertension.      Idiopathic intracranial
    hypertension may progress to blindness if untreated. It is medically probable that
    early diagnosis would have prevented [Owens’s] later development of vision loss.”
    (Footnote omitted.)
    In regard to Dr. Handyside specifically, Dr. Richardson, in his report, states
    that she breached the standard of care “by failing to perform a fundiscopic
    examination and failing to perform cerebral imaging[,] such as [a] head CT or
    preferably [a] brain MRI.”       Further, “[t]he failure to obtain a neurology
    consultation . . . and the failure to admit the patient if urgent follow-up could not
    be obtained also constitutes a bre[a]ch of the standard [of] care.” In regard to
    causation, Richardson opines:
    If Dr. . . . Handyside had performed cerebral imaging[,] such as [a]
    CT or preferably [an] MRI, performed [a] lumbar puncture[,] or
    obtained [a] neurological consultation[,] it is medically probable
    that . . . Owens would have had her condition diagnosed and treated in
    a timelier manner. Early treatment of dural sinus thrombosis reduces
    the likelihood of complications[,] such as idiopathic intracranial
    hypertension. Thus[,] her vision would have most likely been spared
    26
    and she would not have lost vision in the right and left eyes. Severe
    loss of vision is a preventable complication of dural sinus thrombosis.
    (Footnote omitted.)
    Dr. Handyside asserts that Dr. Richardson “merely state[s] that had
    [she] . . . diagnosed [Owens], then [Owens] might have had a better outcome,” but
    fails to explain “how [her] . . . conduct caused the permanent loss of vision.” In
    other words, Richardson “does not explain how and why the complained of delay
    in diagnosis and treatment . . . were substantial factors in causing [Owens’s]
    blindness.”
    An expert report must explain, to a reasonable degree, how and why the
    alleged breach caused the complained of injury based on the facts presented. See
    Jelinek, 328 S.W.3d at 539–40. Here, contrary to Dr. Handyside’s assertions, Dr.
    Richardson’s report does just that. Richardson opines that Handyside’s failure to
    “perform[] cerebral imaging[,] such as [a] CT or preferably [an] MRI, perform[]
    [a] lumbar puncture or obtain[] [a] neurological consultation” resulted in a delay in
    the diagnosis and treatment of Owens’s conditions. And “[t]his delay resulted in
    the development of a complication, severe vision loss due to idiopathic intracranial
    hypertension. Severe vision loss due to intracranial complication can generally be
    easily treated with medication if it is diagnosed early.” Cf. Patterson v. Ortiz, 
    412 S.W.3d 833
    , 839 (Tex. App.—Dallas 2013, no pet.) (holding sufficient report
    “show[ing] that performing the tests and examinations would have led to the
    27
    diagnosis of pneumonia and Raul’s admission to the hospital, where he would have
    received ‘early, aggressive treatment [that], more likely than not, would have saved
    his life’”). An expert may show causation by explaining a chain of events that
    begins with a defendant doctor’s negligence and ends in injury to the plaintiff. See
    McKellar v. Cervantes, 
    367 S.W.3d 478
    , 485 (Tex. App.—Texarkana 2012, no
    pet.); see also Woofter v. Benitez, No. 01-09-00161-CV, 
    2009 WL 3930839
    , at *7
    (Tex. App.—Houston [1st Dist.] Nov. 19, 2009, no pet.) (mem. op.) (“Dr. Flye’s
    report sets forth a chain of events involving breaches of the standard of care by
    each of the defendant physicians, which resulted in Islam’s death.”).
    In regard to Dr. Prater, Dr. Richardson, in his report, states that Prater
    breached the standard of care by “fail[ing] to perform a lumbar puncture on
    [Owens],” “fail[ing] to admit her,” failing to “perform cerebral imagining[,] such
    as [a] head CT or [a] brain MRI,” failing to “obtain a neurological consultation to
    have    [Owens]    assessed   urgently    despite   the   diagnoses     of   possible
    meningoencephalitis and possible cavernous sinus thrombosis,” and failing to
    provide “adequate neurological follow-up” after Owens was discharged from
    Memorial Hermann. In regard to causation, Richardson opines:
    If Dr[]. . . . Prater performed [a] lumbar puncture, ordered cerebral
    imaging[,] such as [a] head CT and preferably [an] MRI, admitted
    [Owens to the hospital] and/or obtained [a] neurological
    consultation, . . . Owens would have likely had a more timely
    diagnosis, earlier treatment and her vision would medically probably
    have been saved. If . . . Prater had not prescribed dexamethazone
    28
    for . . . Owens[,] it is medically probable that her condition would not
    have been exacerbated. It is possible she would have not progressed
    to . . . have [a] loss of vision.
    Further, Richardson states that “[i]f [Owens] was admitted [to the hospital], if a
    neurology consultation was obtained, and if a lumbar puncture had been done, it is
    medically probable that her condition, dural sinus thrombosis[,] would have been
    diagnosed earlier and her vision would have been saved with treatment.” As stated
    above, the treatments available to prevent Owens’s loss of vision are also
    addressed by Richardson in his report.
    Dr. Prater asserts that Dr. Richardson “merely state[s] that had . . . Prater
    diagnosed [Owens], then she might have had a better outcome” and fails to explain
    “how . . . Prater’s conduct caused the permanent loss of vision.” In other words,
    Richardson “does not explain how and why the complained of delay in diagnosis
    and treatment and the prescription of dexamethasone were substantial factors in
    causing [Owens’s] blindness.”
    Contrary to Dr. Prater’s assertions, however, Dr. Richardson’s report
    “explain[s], to a reasonable degree, how and why the [alleged] breach [by Prater]
    caused [Owens’s] injury.” See Jelinek, 328 S.W.3d at 539–40. Richardson opines
    that Prater’s failure to “perform[] [a] lumbar puncture, order[] cerebral imaging[,]
    such as [a] head CT and preferably [an] MRI, admit[] [Owens to the hospital],
    and/or obtain[] [a] neurological consultation” resulted in a delay of the diagnosis
    29
    and treatment of Owens’s conditions.          And “[t]his delay resulted in the
    development of a complication, severe vision loss due to idiopathic intracranial
    hypertension. Severe vision loss due to intracranial complication can generally be
    easily treated with medication if it is diagnosed early.” With earlier detection and
    treatment, Owens’s “vision would medically probably have been saved.”             Cf.
    Patterson, 412 S.W.3d at 839; see also McKellar, 
    367 S.W.3d at 485
    ; Woofter,
    
    2009 WL 3930839
    , at *7.
    In support of their argument that it is insufficient for an expert report to
    merely state that a plaintiff “might have had a better outcome” without linking the
    expert’s conclusion (that the plaintiff might have had a better outcome) to a
    doctor’s alleged breach, Drs. Handyside and Prater rely on Wright. In Wright, the
    plaintiff alleged that a physician’s assistant misread or misplaced an x-ray and,
    therefore, did not discover that the plaintiff had fractured her foot. 79 S.W.3d at
    50. Approximately one month later, the plaintiff’s orthopedic surgeon discovered
    the fracture. Id. The plaintiff served on the defendant the report of an expert, who
    stated that had the x-ray been properly read, the plaintiff “would have had the
    possibility of a better outcome.” Id. at 51. The Texas Supreme Court, after
    recognizing that an expert in his report need not use any particular phrase, held that
    the trial court could have reasonably determined that the report did not represent a
    good-faith effort to summarize the causal relationship. Id. at 53. The supreme
    30
    court noted that the expert in his report simply opined that the plaintiff had “‘the
    possibility of a better outcome,’” and did not sufficiently “link[] the expert’s
    conclusion (that [the plaintiff] might have had a better outcome) to [the hospital’s]
    alleged breach (that it did not correctly read and act upon the x-rays).” Id.
    Here, in contrast, Dr. Richardson does not simply assert that Owens would
    have had the “possibility of a better outcome” if not for Drs. Handyside’s and
    Prater’s alleged breaches of the standard of care. Instead, Richardson explains that
    the doctors’ breaches caused a delay in the diagnosis and treatment of Owens’s
    conditions. As stated in the report: “Untreated dural sinus thrombosis is well
    known to potentially cause idiopathic intracranial hypertension.” The delay in
    diagnosis and treatment “resulted in the development of a complication, severe
    vision loss due to idiopathic intracranial hypertension.” “It is medically probable
    that early diagnosis would have prevented [Owens’s] later development of vision
    loss.”     The treatments available to prevent Owens’s vision loss included
    medication, “serial lumbar punctures,” “lumboperitoneal shunt placement,” and
    “[o]ptic nerve fenestration.”    See Khan v. Ramsey, No. 01-12-00169-CV, 
    2013 WL 1183276
    , at *9 (Tex. App.—Houston [1st Dist.] Mar. 21, 2013, no pet.) (mem.
    op.) (holding expert report sufficient where breach of standard of care caused delay
    in diagnosis, which resulted in “permanent disability”); Foster v. Richardson, 
    303 S.W.3d 833
    , 841 (Tex. App.—Fort Worth 2009, no pet.) (holding expert report
    31
    adequate regarding causation because it explained how doctor’s delayed diagnosis
    subjected patient to prolonged pain); Gelman v. Cuellar, 
    268 S.W.3d 123
    , 130
    (Tex. App.—Corpus Christi 2008, pet. denied) (holding expert report adequate
    regarding breach and causation because it explained had patient “been properly
    monitored and timely treated post-operatively with aggressive respiratory care, she
    would not have developed respiratory insufficiency,” which caused her “anoxic
    brain damage”); In re Barker, 
    110 S.W.3d 486
    , 491 (Tex. App.—Amarillo 2003,
    orig. proceeding) (concluding expert report sufficient because it explained
    negligent failure to recognize medical condition and delay in treatment increased
    severity of plaintiff’s injuries).
    Based on the foregoing, Dr. Richardson’s report represented a “good faith
    effort” to inform Drs. Handyside and Prater of the causal relationship between their
    failure to adhere to the pertinent standard of care and the injury, harm, or damages
    claimed. See Kelly v. Rendon, 
    255 S.W.3d 665
    , 679 (Tex. App.—Houston [14th
    Dist.] 2008, no pet.) (emphasizing expert reports “are simply a preliminary method
    to show a plaintiff has a viable cause of action that is not frivolous or without
    expert support”). Accordingly, we hold that the trial court erred to the extent that it
    granted Drs. Handyside’s and Prater’s motions to dismiss Owens’s claims on the
    32
    ground that Richardson’s expert report did not adequately address the issue of
    causation.11
    We sustain Owens’s second issue, in part.
    Vicarious Liability
    In her third issue, Owens argues that the trial court erred in dismissing her
    vicarious-liability claims against Memorial Hermann because an expert report is
    not necessary regarding such claims. Memorial Hermann asserts that dismissal of
    Owens’s vicarious-liability claims against it is mandatory because Owens “failed
    to serve [a sufficient] expert report as to the individual physicians’ conduct that [is]
    the basis of the vicarious liability claim[s].”
    In addition to her direct-liability claims against Memorial Hermann, Owens
    alleges that it is vicariously liability for the conduct of its “nurses, technicians,
    servants and[/]or agents” and “Amy Rasmussen, M.D.; Brian Zachariah, M.D.;
    Krista G. Handyside, M.D.; Inez A. Serrano, P.A.; Samuel J. Prater, M.D.; [and]
    Kenneth A. Totz, [D.O., FACEP].”
    “[W]hen a health care liability claim involves a vicarious liability theory,
    either alone or in combination with other theories, an expert report that meets the
    statutory standards as to the employee is sufficient to implicate the employer’s
    11
    In her brief, Owens also asserts that Dr. Richardson’s report adequately addresses
    the standard of care as it relates to the doctors. However, because Drs. Handyside
    and Prater did not object to the report on this ground, we do not consider this
    portion of Owens’s argument.
    33
    conduct under the vicarious theory.” Certified EMS, Inc. v. Potts, 
    392 S.W.3d 625
    ,
    632 (Tex. 2013); see also Gardner v. U.S. Imaging, Inc., 
    274 S.W.3d 669
    , 671–72
    (Tex. 2008) (“When a party’s alleged health care liability is purely vicarious, a
    report that adequately implicates the actions of that party’s agents or employees is
    sufficient.”). In other words, a report that is sufficient as to an employee, whose
    alleged negligent conduct a vicarious-liability claim is based, is also sufficient as to
    the employer health care provider. See, e.g., Ctr. for Neurological Disorders, P.A.
    v. George, 
    261 S.W.3d 285
    , 295 (Tex. App.—Fort Worth 2008, pet. denied) (“[I]f
    the expert report is sufficient as to the claims against Dr. Ward, and we have held
    that it is[,] . . . then the report is sufficient as to claims against CND that are based
    on Dr. Ward’s alleged negligence.” (Footnote omitted.)).
    Here, we have held that the trial court erred in dismissing Owens’s direct-
    liability claims against Drs. Handyside and Prater because Dr. Richardson’s expert
    report complies with chapter 74 regarding Owens’s allegations against the doctors.
    Therefore, contrary to Memorial Hermann’s assertion, dismissal of Owens’s
    vicarious-liability claims against it is not “mandatory.”        Instead, Owens may
    proceed on her vicarious-liability claims against Memorial Hermann based on the
    conduct of Drs. Handyside and Prater. See Potts, 392 S.W.3d at 632; Gardner,
    274 S.W.3d at 671–72.
    34
    Further, we note that Owens alleges that Memorial Hermann is vicariously
    liable not only for the conduct of Drs. Handyside and Prater, but also for the
    conduct of “nurses, technicians, servants and[/]or agents,” Drs. Rasmussen,
    Zachariah, and Totz, and physician assistant Serrano.         Because Owens may
    proceed on her vicarious-liability claims against Memorial Hermann based on the
    alleged negligence of Drs. Handyside and Prater, she may also proceed on her
    vicarious-liability claims against Memorial Hermann based on the alleged
    negligent conduct of the other individuals. See TTHR Ltd. P’ship v. Moreno, 
    401 S.W.3d 41
    , 45 (Tex. 2013) (holding plaintiff’s vicarious-liability claim against
    hospital for actions of nurses could proceed because expert report adequate
    regarding plaintiff’s vicarious-liability claim for negligent acts of doctors); Potts,
    392 S.W.3d at 629–32 (plaintiff entitled to proceed with her entire suit against
    health care provider so long as expert report valid as to one theory of liability
    against defendant); Huepers v. St. Luke’s Episcopal Hosp., No. 01-11-00074-CV,
    
    2013 WL 1804470
    , at *3–5 (Tex. App.—Houston [1st Dist.] Apr. 30, 2013, no
    pet.) (mem. op.) (holding no further report required where amended petition added
    new theory of vicarious liability against hospital based on nursing negligence
    because initial report sufficient as to plaintiff’s vicarious-liability claim against
    hospital based on doctor conduct).
    35
    And because Dr. Richardson’s report satisfies the requirements of chapter 74
    as to Memorial Hermann’s vicarious liability for the conduct of Drs. Handyside
    and Prater, Owens may also proceed on her direct-liability claims against
    Memorial Hermann.12 See Potts, 392 S.W.3d at 629–32 (holding plaintiff’s direct-
    liability claim against nursing staffing agency could proceed because expert report
    submitted by plaintiff supported her vicarious-liability claims); Children’s Med.
    Ctr. of Dall. v. Durham, 
    402 S.W.3d 391
    , 403–04 (Tex. App.—Dallas 2013, no
    pet.) (concluding, because expert report valid as to vicarious-liability claims
    against hospital, plaintiffs’ direct-liability claims against hospital “may proceed as
    well”).
    Accordingly, we hold that the trial court erred in granting Memorial
    Hermann’s motion to dismiss Owens’s direct- and vicarious-liability claims against
    it.
    We sustain Owens’s third issue.
    12
    Because Dr. Richardson’s expert report is sufficient as to Owens’s vicarious-
    liability claims against Memorial Hermann, based on the conduct of Drs.
    Handyside and Prater, we need not consider the report’s sufficiency as to Owens’s
    direct-liability claims against Memorial Hermann. See San Jacinto Methodist
    Hosp. v. McCoy, No. 14-12-00682-CV, 
    2013 WL 3009318
    , at *5 n.3 (Tex. App.—
    Houston [14th Dist.] June 13, 2013, no pet.) (mem. op.). Therefore, as stated
    previously, we do not address the portion of Owens’s second issue in which she
    asserts that Richardson’s report is adequate as to the issues of standard of care and
    causation as it pertained to her direct-liability claims against Memorial Hermann.
    36
    Conclusion
    We reverse the trial court’s dismissal of Owens’s health care liability claims
    against Memorial Hermann and Drs. Handyside, Prater, and Totz. And we remand
    Owens’s health care liability claims against them to the trial court for further
    proceedings consistent with this opinion.
