    NANCY CARMEN CURNEL AND RONALD CURNEL, Appellants
    V.
    HOUSTON METHODIST HOSPITAL-WILLOWBROOK AND MICHAEL
    ESANTSI, Appellees
    On Appeal from the 55th District Court
    Harris County, Texas
    Trial Court Case No. 2016-36453
    OPINION ON REHEARING1
    1
    Appellants, Nancy and Ronald Curnel, have filed a motion for rehearing of our
    October 31, 2017 memorandum opinion and judgment. We grant the motion,
    withdraw our memorandum opinion and judgment of October 31, 2017, and issue
    this opinion and a new judgment in their stead.
    This is an interlocutory appeal from the trial court’s order dismissing health
    care liability claims for failure to serve adequate expert reports. See TEX. CIV.
    PRAC. & REM. CODE §§ 51.014(a)(9), 74.351(a), (b).
    According to the expert reports, Nancy Curnel presented to the emergency
    room of Houston Methodist Hospital-Willowbrook with elevated liver enzymes
    caused by a recently prescribed antibiotic. Curnel was examined by a hospitalist,
    Dr. Michael Esantsi, who misdiagnosed her with viral hepatitis; ordered that she
    continue taking her current medications, including the antibiotic that was causing
    her elevated liver enzymes; and admitted her to the hospital. Once admitted,
    Curnel continued to receive the hepatotoxic antibiotic, and she began to receive
    another well-known hepatotoxic medication, acetaminophen, again by an order of
    Esantsi. On the third day of her hospitalization, Curnel was examined by a
    gastroenterologist, who noted that she might be suffering from drug-induced liver
    injury. He ordered a biopsy of Curnel’s liver to test for other potential causes.
    Later that same day, another hospitalist discontinued the antibiotic. Curnel’s liver
    enzymes began to improve. Curnel’s physicians did not cancel or postpone the
    biopsy. On the morning of the fifth day of Curnel’s hospitalization, a blood clotting
    test ordered by Esantsi to clear Curnel for the biopsy returned as normal, and a
    radiologist performed the biopsy as scheduled. During the biopsy, the radiologist
    nicked Curnel’s artery, causing her severe injuries.
    2
    Curnel and her husband, Ronald, asserted health care liability claims against
    Esantsi and Methodist, among others. They served a series of expert reports from a
    gastroenterologist, Dr. Todd Sheer, and a registered nurse, Julie Fomenko. Esantsi
    and Methodist both filed motions to dismiss. The trial court found that the expert
    reports were deficient as to both Esantsi and Methodist, denied the Curnels’
    request for an extension to cure the deficiencies, and dismissed the Curnels’ claims
    with prejudice. The Curnels filed a motion for reconsideration, supported by
    amended expert reports, which the trial court denied as well.
    In three issues, the Curnels contend that the trial court abused its discretion
    by (1) granting Esantsi’s and Methodist’s motions to dismiss, (2) denying their
    request for an extension to cure, and (3) denying their motion for reconsideration.
    We hold that the expert reports were deficient but may be curable. Therefore, we
    reverse the trial court’s order dismissing the Curnels’ claims against Esantsi and
    Methodist and remand the case for further proceedings.
    Factual Background
    The expert reports of Sheer and Fomenko provide the background facts in
    this case. There are five reports from Sheer (one original and four supplemental)
    and three reports from Fomenko (one original and two supplemental). We accept
    the expert reports’ factual statements for the limited purpose of this appeal and do
    not address the merits of the Curnels’ claims. See Bowie Mem’l Hosp. v. Wright,
    3
    
    79 S.W.3d 48
    , 52 (Tex. 2002) (per curiam) (review of Chapter 74 report is limited
    to four corners of report).
    Curnel is prescribed an antibiotic that can cause elevated liver enzymes
    On October 4, 2015, Nancy Curnel presented to a local walk-in clinic “with
    a complaint of two days of subjective fever, rash, chronic cough, generalized pain,
    nasal congestion, dysuria, and diarrhea.” At the time, Curnel was on “multiple
    medications,” including “acyclovir, alprazolam, duloxetine, hydrochlorothiazide,
    lisdexamfetamine, levothyroxine, zolpidem, and nasonex.” Curnel was examined
    by a nurse practitioner, who diagnosed Curnel with a urinary tract infection and
    prescribed her the antibiotic nitrofurantoin, “100mg twice a day for 7 days.”
    Nitrofurantoin (also known as Macrodantin or Macrobid) is known for potential
    hepatotoxic effects and can cause drug-induced liver injury (DILI).
    Curnel presents to the Methodist ER with elevated liver enzymes
    Four days later, on Thursday, October 8, Curnel presented to the Methodist
    emergency room. According to Dr. Sheer’s expert reports, Curnel had been sent to
    the ER “by her primary medical provider to find out why recent blood work
    identified abnormal liver tests (hepatitis).” Curnel’s “medical history was negative
    for drug or alcohol abuse and chronic liver disease.” “She was taking several
    medications for longstanding medical conditions, with no history that these
    medications had caused hepatotoxicity in the past.” The only “new drug” she was
    4
    taking was the nitrofurantoin. After she began taking nitrofurantoin, “liver function
    studies performed by her primary care provider demonstrated elevated values.”
    Curnel told the nursing staff that she had been sent to the ER by her primary
    care physician because recent blood work indicated that she had elevated liver
    enzymes. An ER nurse took Curnel’s medical history, noting that “Curnel had
    recently started nitrofurantoin and was then referred to the hospital for evaluation
    of elevated liver enzymes.” However, there is no documentation that the nurse
    evaluated Curnel’s “current medications, including nitrofurantoin,” for “potential
    hepatotoxicity.”
    After the nurse took Curnel’s medical history, Curnel was examined by an
    emergency medicine physician, Dr. Scott Wiesenborn. Wiesenborn noted that
    Curnel had recently begun taking nitrofurantoin and had been referred to the ER
    for elevated liver enzymes. Wiesenborn ordered that Curnel’s liver enzymes be
    tested, and the results confirmed that several of her liver enzymes were abnormally
    high, including her alanine transaminase (ALT), aspartate transaminase (AST), and
    alkaline phosphatase (ALP). Wiesenborn diagnosed Curnel with a fever and
    “elevated liver function tests/probable acute hepatitis,” although he did not specify
    whether it was “drug, viral, autoimmune, etc.”
    5
    Curnel is hospitalized
    Wiesenborn called the on-duty hospitalist, Dr. Michael Esantsi, to determine
    whether to admit Curnel for hospitalization. According to Sheer’s expert reports,
    Esantsi’s “history and physical” was “not significantly different from the one
    performed in the ER” by Wiesenborn. Esantsi documented that Curnel had started
    nitrofurantoin, but he did “not list this in his Medications section.” He diagnosed
    Curnel with “abnormal liver function tests,” specifying that the probable cause was
    “viral-induced hepatitis.” According to Sheer, “[d]rug-induced liver injury [was]
    not considered in the history and physical,” and Esantsi’s “plan include[d]
    continuing current regular home medications.” Esantsi ordered that Curnel take
    “nitrofurantoin 100 mg capsule oral two times daily” and that she undergo a
    gastrointestinal consultation.
    One of the nurses documented Esantsi’s order concerning Curnel’s
    medications, “which included nitrofurantoin SR (Macrobid) 100 mg capsule oral
    two times daily.” There is no documentation that the nurses ever developed “a plan
    for an evaluation for the hepatotoxic potential of the medications, and there is no
    documentation elsewhere in the medical record that such evaluation was
    completed.”
    That afternoon, Curnel was transferred from the ER to the medical-surgical
    unit, where she was examined by a gastroenterologist, Dr. Steven Ugbarugba.
    6
    Ugbarugba’s consultation notes made “no mention” of Curnel “starting
    nitrofurantoin recently” and “omit[ted] a list of her medications.” Ugbarugba
    performed a number of tests, which ruled out a number of potential causes of
    Curnel’s elevated liver enzymes.2 Ugbarugba did not note nitrofurantoin as a
    potential cause of Curnel’s elevated liver enzymes. Again quoting from Sheer’s
    reports, there is “no documentation that drug-induced liver injury [was]
    considered” by Ugbarugba at that time.
    Later that evening, Curnel received a dose of nitrofurantoin, which was
    “dispensed from the pharmacy” and “administer[ed]” by one of the nurses.
    On the morning of Friday, October 9, Curnel’s liver enzymes were tested
    again. The test results showed a “slight increase” in both her ALT and AST.
    Curnel underwent additional testing, which indicated that she did not have viral
    hepatitis but was suffering from DILI instead. A complete blood count (CBC)
    revealed that Curnel had eosinophilia, a condition that is “indicative” or
    “suggestive” of DILI.
    According to Sheer, Esantsi’s notes indicate that, when he saw Curnel again
    that day, he “repeat[ed] the running diagnosis of probable viral hepatitis, despite
    negative test results,” with “no documentation that drug-induced liver injury [was]
    2
    Specifically, Ugbarugba ruled out autoimmune hepatitis, viral hepatitis, lupus
    hepatitis, celiac disease, Epstein-Barr virus, Parvovirus PCRs, primary biliary
    cholangitis, and ulcers.
    7
    considered.” At the nurses’ request, Esantsi ordered that Curnel begin to take
    acetaminophen,    “another    well-known     hepatotoxic   medication.”    A   nurse
    administered the medication to Curnel that afternoon.
    That evening, Curnel received another dose of nitrofurantoin, “dispensed
    from the pharmacy” and “administer[ed]” by another nurse.
    On the morning of Saturday, October 10, Curnel received yet another dose
    of nitrofurantoin. Her liver enzymes were tested again, and the results showed
    increases in her ALT and ALP, and a slight decrease in her AST, which
    nevertheless remained abnormally high. The results also showed a “slight rise” in
    her bilirubin.
    Later that day, she was examined again by Dr. Ugbarugba, who ordered that
    Curnel undergo a liver biopsy. Ugbarugba wrote a progress note, which
    “reaffirm[ed]” the general diagnosis of “acute hepatitis” but added that the etiology
    remained “unclear” and that there was a “possibility” that the hepatitis was
    “medication-induced.” Sheer’s expert reports state that this is the “first
    documentation” of a medical provider considering DILI as a potential cause of
    Curnel’s elevated liver enzymes. Ugbarugba “recommend[ed] holding Acyclovir,
    Vyvance, and Tylenol specifically,” and he made “a general suggestion to ‘hold
    hepatotoxic medications.’”
    8
    Later that afternoon, Curnel was examined by another physician, Dr. Yamini
    Naygandhi, who was “covering for Esantsi.” Naygandhi noted that Curnel might
    be suffering from “medication related hepatitis” (i.e., DILI) instead of “viral”
    hepatitis and ordered a review of Curnel’s medications “to find out what [was]
    causing [her] elevated LFT [liver function tests].” She also ordered that Curnel
    discontinue nitrofurantoin.3
    By Sunday, nitrofurantoin was “no longer on [Curnel]’s patient medication
    list and was not administered.” Her bilirubin and ALP increased, but her ALT and
    AST decreased.
    Curnel’s artery is nicked during her liver biopsy
    On the morning of Monday, October 12, the day of Curnel’s scheduled liver
    biopsy, Curnel’s enzymes showed “further improvement.” Her bilirubin began to
    decrease, her AST continued to decrease, and her ALT and ALP underwent “non-
    significant changes.”
    At 9:00 a.m., Curnel was examined for a third time by Ugbarugba. His
    progress note contained the “exact” same “assessment from the day prior” except
    that it noted, “Liver bx today.” “A pre-procedure prothrombin time/INR ordered by
    3
    None of the       physicians   specifically   ordered   that   Curnel   discontinue
    acetaminophen.
    9
    Dr. Esantsi return[ed] as normal (this was the first time checked since
    presentation).”4
    At 10:30 a.m., a radiologist, Dr. Mark Brodie, performed the biopsy. He
    obtained two “cores,” which showed that “the liver function abnormalities were
    due to medication effects.” During the biopsy, Brodie nicked Curnel’s artery,
    causing severe injuries. Curnel required multiple blood transfusions, medications
    to maintain circulation, mechanical ventilation, prolonged resuscitation, and
    extended ICU care. According to Sheer, Curnel “will have a slow and painful
    recovery.”
    Procedural History
    The Curnels asserted health care liability claims against Esantsi and
    Methodist, among others. The Curnels served Esantsi and Methodist with a series
    of expert reports from Sheer and Fomenko. Sheer’s reports addressed both Esantsi
    and Methodist, while Fomenko’s addressed only Methodist.
    Esantsi and Methodist filed objections and motions to dismiss for failure to
    serve adequate expert reports. The Curnels responded that the reports were
    adequate. They requested that the trial court deny the motions to dismiss or,
    alternatively, grant them a 30-day extension to cure any deficiencies in the reports.

    procedures/prothrombin-time/about/pac-20384661.
    10
    The trial court heard the motions to dismiss and found that the combined
    expert reports of Sheer and Fomenko were deficient as to both Esantsi and
    Methodist. The trial court sustained Esantsi’s and Methodist’s objections, denied
    the Curnels’ request for a 30-day extension to cure, and dismissed the Curnels’
    claims with prejudice.
    The Curnels filed a motion for reconsideration, supported by amended
    expert reports. The trial court denied the motion, and the Curnels appealed.
    Motions to Dismiss
    In their first issue, the Curnels contend that the trial court abused its
    discretion in granting Esantsi’s and Methodist’s motions to dismiss for failure to
    serve adequate expert reports.
    A.    Applicable law and standard of review
    Under the Medical Liability Act, a plaintiff asserting health care liability
    claims must timely serve each defendant physician and health care provider with
    one or more expert reports and a curriculum vitae of each expert whose opinion is
    offered to substantiate the merits of the claims. TEX. CIV. PRAC. & REM.
    CODE § 74.351(a), (i); see Mangin v. Wendt, 
    480 S.W.3d 701
    , 705 (Tex. App.—
    Houston [1st Dist.] 2015, no pet.). The expert report must provide a “fair
    summary” of the expert’s opinions regarding the (1) applicable standards of care,
    (2) manner in which the care rendered by the physician or health care provider
    11
    failed to meet the standards, and (3) causal relationship between that failure and
    the   injury,   harm,   or   damages     claimed.   TEX.   CIV.    PRAC.   &      REM.
    CODE § 74.351(r)(6). “No particular words or formality are required, but bare
    conclusions will not suffice.” Scoresby v. Santillan, 
    346 S.W.3d 546
    , 556 (Tex.
    2011). Instead, the report must explain the basis of the expert’s statements and link
    the expert’s conclusions to the facts of the case. Jelinek v. Casas, 
    328 S.W.3d 526
    ,
    539 (Tex. 2010).
    For standard of care and breach, the expert report must explain what the
    physician or health care provider should have done under the circumstances and
    what the physician or health care provider did instead. Am. Transitional Care Ctrs.
    of Tex., Inc. v. Palacios, 
    46 S.W.3d 873
    , 880 (Tex. 2001). For causation, the expert
    report must explain how and why the physician’s or health care provider’s breach
    proximately caused the plaintiff’s injury. Columbia Valley Healthcare Sys., L.P. v.
    Zamarripa, 
    526 S.W.3d 453
    , 459–60 (Tex. 2017).
    Proximate     cause    has   two     components:     (1)    cause-in-fact    and
    (2) foreseeability. 
    Id. at 460.
    A physician’s or health care provider’s breach was a
    cause-in-fact of the plaintiff’s injury if the breach was a substantial factor in
    bringing about the harm, and absent the breach (i.e., but for the breach) the harm
    would not have occurred. 
    Id. Even if
    the harm would not have occurred absent the
    defendant’s breach, “the connection between the defendant and the plaintiff’s
    12
    injuries simply may be too attenuated” for the breach to qualify as a substantial
    factor. Allways Auto Grp., Ltd. v. Walters, 
    530 S.W.3d 147
    , 149 (Tex. 2017) (per
    curiam) (quoting Union Pump Co. v. Allbritton, 
    898 S.W.2d 773
    , 776 (Tex. 1995)).
    A breach is not a substantial factor if it “does no more than furnish the condition
    that makes the plaintiff’s injury possible.” 
    Id. A physician’s
    or health care
    provider’s breach is a foreseeable cause of the plaintiff’s injury if a physician or
    health care provider of ordinary intelligence would have anticipated the danger
    caused by the negligent act or omission. See Price v. Divita, 
    224 S.W.3d 331
    , 336
    (Tex. App.—Houston [1st Dist.] 2006, pet. denied).
    The plaintiff may serve reports of separate experts regarding different
    physicians or health care providers or regarding different issues arising from the
    conduct of a single physician or health care provider. TEX. CIV. PRAC. & REM.
    CODE § 74.351(i). However, only a qualified physician may give opinion testimony
    about the causal relationship between the claimed injury, harm, or damages and the
    alleged departure from the applicable standard of care. See 
    id. § 74.351(r)(5)(C).
    The expert report is not required to prove the plaintiff’s case but only to
    provide notice of the conduct forming the basis of the plaintiff’s claim. Gracy
    Woods I Nursing Home v. Mahan, 
    520 S.W.3d 171
    , 189 (Tex. App.—Austin 2017,
    no pet.). The report “need not anticipate or rebut all possible defensive theories that
    may ultimately be presented” in the case. Owens v. Handyside, 
    478 S.W.3d 172
    ,
    13
    187 (Tex. App.—Houston [1st Dist.] 2015, pet. denied). Nor must the report “rule
    out every possible cause of the injury, harm, or damages claimed.” Baylor Med.
    Ctr. at Waxahachie, Baylor Health Care Sys. v. Wallace, 
    278 S.W.3d 552
    , 562
    (Tex. App.—Dallas 2009, no pet.).
    In reviewing the adequacy of an expert report, a trial court may not consider
    an expert’s credibility, the data relied upon by the expert, or the documents that the
    expert failed to consider at this pre-discovery stage of the litigation. See Mettauer
    v. Noble, 
    326 S.W.3d 685
    , 691 (Tex. App.—Houston [1st Dist.] 2010, no pet.);
    Gonzalez v. Padilla, 
    485 S.W.3d 236
    , 245 (Tex. App.—El Paso 2016, no pet.).
    Instead, the trial court must limit its review to the “four corners” of the expert
    report and, when the question of adequacy hinges on the expert’s qualifications,
    the “four corners” of the expert’s curriculum vitae. 
    Mangin, 480 S.W.3d at 706
    .
    The statute’s purpose is not to determine the merits of the claim but to rule
    out frivolous lawsuits at the onset of litigation, before the parties have conducted
    full discovery. Ross v. St. Luke’s Episcopal Hosp., 
    462 S.W.3d 496
    , 502 (Tex.
    2015); 
    Mangin, 480 S.W.3d at 706
    . As we have explained:
    The requirement to serve an expert report arises at the outset of
    litigation and before the opportunity for the plaintiff to engage in
    significant discovery, including taking oral depositions of the
    defendants. As such, the statute itself contemplates that the amount
    and quality of evidence available at the time of drafting the expert
    reports will be less than that available at trial on the merits or even the
    summary-judgment stage.
    14
    
    Mangin, 480 S.W.3d at 713
    (citations omitted). Thus, the requirements of the
    statute have been variously described as a “lenient standard,”5 “low threshold,”6
    and “relatively low bar.”7
    If the plaintiff “fails to timely serve an expert report, then on the affected
    health care provider’s motion the trial court must dismiss the pertinent health care
    liability claim with prejudice and award attorney’s fees.” Baty v. Futrell, 
    543 S.W.3d 689
    , 692 (Tex. 2018) (citing TEX. CIV. PRAC. & REM. CODE § 74.351(b)).
    “However, if the motion challenges the adequacy of an otherwise timely report, the
    trial court may grant the motion ‘only if it appears to the court, after hearing, that
    the report does not represent an objective good faith effort to comply with the
    [Act’s] definition of an expert report.’” 
    Baty, 543 S.W.3d at 692
    –93 (quoting TEX.
    CIV. PRAC. & REM. CODE § 74.351(l)).
    A report qualifies as an objective good faith effort to avoid dismissal if it
    discusses each element with sufficient specificity that it (1) informs the defendant
    of the specific conduct the plaintiff questions and (2) provides a basis for the trial

    determining whether an expert report constitutes an objective good faith effort to
    address each element, “a trial court may not draw inferences; instead, it must
    exclusively rely upon the information contained within the four corners of the
    report.” Cornejo v. Hilgers, 
    446 S.W.3d 113

    We review a trial court’s ruling on a motion to dismiss a health care liability
    claim for an abuse of discretion. Van Ness v. ETMC First Physicians, 
    461 S.W.3d 140

    Id. B. Adequacy
    of expert reports on Esantsi
    The Curnels supported their claim against Esantsi with expert reports from
    Sheer. The trial court found that Sheer’s reports were deficient on all three
    elements.
    1.     Sheer’s opinions on elements of standard of care and breach
    We begin by considering whether Sheer’s reports provide adequate opinions
    on the first two elements: standard of care and breach. In his reports, Sheer
    16
    explains that the standard of care required Esantsi to take certain actions and to
    refrain from taking others throughout the course of Curnel’s treatment at
    Methodist.
    Sheer writes that, as Curnel’s “primary physician” at the hospital, Esantsi
    was “responsible” for the “decision to admit and discharge” her. At the “most
    basic” level, a hospitalist like Esantsi must “understand the effect of medications
    on a patient, especially when evaluating liver function.” When a patient presents
    with elevated liver enzymes, “medications should be at the top of the list of
    potential causes, which is especially true when the patient has recently initiated a
    course of a frequently implicated agent such as nitrofurantoin.” And, Sheer
    continues, when a patient’s elevated liver enzymes are “drug-induced,” a liver
    biopsy is “rarely helpful.”
    According to Sheer, when Curnel presented to the hospital after having
    recently initiated an antibiotic well-known for its hepatotoxic potential, the
    standard of care required Esantsi to “evaluate the hepatotoxic potential” of
    Curnel’s medications; “recognize drug-induced liver injury as the probable cause
    of [her] elevated liver enzymes”; “discontinue the offending drug,” nitrofurantoin;
    refrain from ordering other hepatotoxic medications; and “discharge her to be
    followed as an outpatient with her primary care physician to confirm normalization
    of the liver tests on serial lab testing.” Sheer explains that Esantsi breached this
    17
    standard by failing to take any of these steps. Esantsi failed to evaluate the
    hepatotoxic potential of her medications, recognize DILI as the probable cause of
    her elevated liver enzymes, discontinue the antibiotic, refrain from ordering other
    hepatotoxic medication, and discharge her for outpatient monitoring. Instead,
    Esantsi misdiagnosed Curnel with probable viral hepatitis, ordered that she
    continue to take nitrofurantoin and begin to take hepatotoxic acetaminophen, and
    admitted her for hospitalization and “unnecessary testing.”
    After Curnel was admitted for hospitalization, Sheer explains, Esantsi
    continued to be responsible for deciding when to discharge her, and the standard of
    care required him to recognize that a liver biopsy was not “warranted” or
    “justified” under the circumstances.8 Sheer further explains that Esantsi breached
    this standard by “maintaining [Curnel’s] admission to the hospital for the biopsy”
    and ordering a pre-procedure prothrombin time test “in preparation of the liver
    biopsy.”
    Thus, in his reports, Sheer explains in detail what he believes the standard of
    care required Esantsi to have done under the circumstances and what Esantsi did
    8
    Sheer explains: “A physician must have evidence that the information to be
    obtained from a liver biopsy warrants the risk before the procedure is performed.
    That did not exist in this case. A liver biopsy is most often performed for
    evaluation of abnormal liver tests once medication review, thorough history and
    physical examination, and complete blood testing has been performed and are not
    indicative of a cause. Liver biopsy is not indicated for a stable patient without
    evidence of acute liver failure (which Ms. Curnel did not have) when the workup
    (including medication review) is incomplete.”
    18
    instead. See 
    Palacios, 46 S.W.3d at 880
    . We hold that Sheer’s reports provide
    adequate opinions on the standard of care applicable to Esantsi and the manner in
    which the care rendered by Esantsi failed to meet that standard. See TEX. CIV.
    PRAC. & REM. CODE § 74.351(r)(6).
    2.    Sheer’s opinion on element of causation
    We next consider whether Sheer’s reports provide an adequate opinion on
    the third element: causation. To show causation, Sheer explains a chain of events
    that begins with Esantsi’s initial breaches—Esantsi’s failure to evaluate Curnel’s
    medications for hepatotoxic potential when she first presented, to diagnose her
    with DILI, and to discharge her for outpatient monitoring. He instead
    misdiagnosed her with viral hepatitis, ordered that she continue to take the
    contraindicated antibiotic and another hepatotoxic medication, and improperly
    admitted her for hospitalization and unnecessary testing. The chain of the events
    then continues to Esantsi’s subsequent breaches—Esantsi’s act and omissions in
    continuing to misdiagnose Curnel with viral hepatitis, maintaining her admission to
    the hospital, and ordering the prothrombin time test in preparation for the biopsy.
    And the chain ends with the unwarranted biopsy taking place as scheduled.
    The chain of events leading up to Curnel’s injuries includes many other acts
    by many other actors. These actors notably include Ugbarugba, who ordered the
    liver biopsy even though he considered DILI a potential cause of Curnel’s elevated
    19
    liver enzymes and Curnel showed improvement after nitrofurantoin was
    discontinued, and Brodie, who actually performed the biopsy and nicked Curnel’s
    artery.
    An event that starts a chain of events can be too attenuated from an injury to
    cause it. See Providence Health Ctr. v. Dowell, 
    262 S.W.3d 324
    , 330 (Tex. 2008)
    (holding that medical providers’ “negligence was too attenuated from the [harm] to
    have been a substantial factor in bringing it about”); Shenoy v. Jean, No. 01-10-
    01116-CV, 
    2011 WL 6938538
    , at *9 (Tex. App.—Houston [1st Dist.] Dec. 29,
    2011, pet. denied) (mem. op.) (“A causal link can be too attenuated to satisfy the
    causation requirement for an expert report.”). It is not enough that one event
    occurred before the other; that is only evidence of but-for causation. Shenoy, 
    2011 WL 6938538
    , at *9; see 
    Jelinek, 328 S.W.3d at 533
    (“Care must be taken to avoid
    the post hoc ergo propter hoc fallacy, that is, finding an earlier event caused a later
    event merely because it occurred first.”). Rather, the event must have been a
    substantial factor in bringing about the harm. 
    Zamarripa, 526 S.W.3d at 460
    . And
    an event is not a substantial factor if it is “too attenuated” from the harm or “does
    no more than furnish the condition that makes the plaintiff’s injury possible.’”
    
    Walters, 530 S.W.3d at 149
    (quoting 
    Allbritton, 898 S.W.2d at 776
    ).
    Esantsi’s initial breaches—the breaches he committed when Curnel first
    presented to Methodist—are too attenuated from Curnel’s injuries to be considered
    20
    a substantial factor in bringing those injuries about. It is true that, if Esantsi had
    followed the identified standard of care when determining whether to admit
    Curnel—had he recognized that Curnel was likely suffering from DILI caused by
    the recently-prescribed nitrofurantoin, discontinued the nitrofurantoin, and
    discharged her for outpatient monitoring—then Curnel’s liver would have never
    been biopsied, and her injuries would have never occurred. Nevertheless, Esantsi’s
    initial breaches, which occurred days before the biopsy and before she was even
    admitted to the hospital, did “no more than furnish the condition” that made
    Curnel’s injury “possible.” 
    Id. That is,
    as a result of Esantsi’s initial breaches,
    Curnel was admitted for hospitalization, which made it possible for Ugbarugba to
    order the biopsy and for Brodie to perform the biopsy, among other causal links in
    the chain. Given the numerous different acts by other physicians and nurses during
    the multiple days between Curnel’s admission and her biopsy, Esantsi’s initial
    breaches do not constitute a cause-in-fact of Curnel’s injuries. See 
    Zamarripa, 526 S.W.3d at 461
    (holding that expert reports were deficient because they failed to
    explain how hospital proximately caused death of pregnant patient); 
    Dowell, 262 S.W.3d at 330
    (holding that “the defendants’ negligence was too attenuated from
    the [harm] to have been a substantial factor in bringing it about”); Shenoy, 
    2011 WL 6938538
    , at *9 (holding that expert report was deficient on causation because
    physician’s negligence in clearing patient for surgery was “too attenuated” from
    21
    patient’s death from post-surgery complications); cf. Allways Auto Grp., Ltd. v.
    Walters, 
    530 S.W.3d 147
    , 147–49 (Tex. 2017) (per curiam) (holding that car
    dealership did not proximately cause collision between intoxicated motorist and
    other driver by providing loaner vehicle to motorist 18 days before collision
    occurred, despite fact that motorist was also intoxicated when dealership provided
    him vehicle).
    In   his   reports,   Sheer    identifies   two   subsequent    breaches    by
    Esantsi: (1) “maintaining [Curnel’s] admission to the hospital for the biopsy” and
    (2) ordering a pre-procedure prothrombin time test “in preparation of the liver
    biopsy.” To conclude that either of these subsequent breaches was a substantial
    factor in bringing about Curnel’s injuries, we would have to infer that Esantsi had a
    duty to prevent the biopsy from taking place or that he participated in the decision
    to biopsy Curnel’s liver in a manner that was “collaborative,” much like the “the
    screening, diagnosis, and treatment” of the two defendant-physicians in
    Bustamante v. Ponte was “collaborative.” 
    529 S.W.3d 447
    , 457 (Tex. 2017). This
    is particularly true given that Ugbarugba possessed the information that DILI was a
    potential cause of Curnel’s elevated liver enzymes and nevertheless ordered a
    biopsy. The reports do not state how Esantsi “had either the right or the means to
    persuade” Ugbarugba and Brodie to cancel the biopsy. 
    Zamarripa, 526 S.W.3d at 461
    . Nor do they otherwise explain whether Esantsi “had any say in the matter.”
    22
    
    Id. We hold
    that Sheer’s reports on Esantsi do not provide an adequate opinion on
    cause-in-fact.
    We further hold that Sheer’s reports do not provide an adequate opinion on
    foreseeability, either. In his reports, Sheer explains that, because the liver is “very
    vascular” and “it is not possible to visualize all of the blood vessels during the
    biopsy,” “in the process of removing pieces of liver tissues, there is [a] risk of
    cutting one or more blood vessels.” Sheer does not state, however, whether this
    risk was known to Esantsi—who is not a gastroenterologist and does not perform
    liver biopsies—or should have been recognized before the biopsy. Nor can we
    draw this inference from Sheer’s reports. 
    Cornejo, 446 S.W.3d at 123
    . Sheer does
    not address whether the risk was generally known or recognized by hospitalists
    like Esantsi before the surgery. Nor does Sheer provide information demonstrating
    that the risk is part of the informed consent disclosures or that a hospitalist of
    ordinary intelligence would have anticipated the danger of a patient’s blood vessel
    being cut during this type of procedure. See 
    Price, 224 S.W.3d at 336
    .
    We hold that Sheer’s reports on Esantsi fail to adequately address both
    components of proximate cause.
    C.    Adequacy of expert reports on Methodist
    The Curnels supported their claim against Methodist with expert reports
    from Fomenko and Sheer. Fomenko’s expert reports address standard of care and
    23
    breach,9 while Sheer’s address causation. The trial court found that the combined
    expert reports were deficient on all three elements.
    1.     Fomenko’s opinions on elements of standard of care and breach
    We begin our analysis by considering whether Fomenko’s reports provide
    adequate opinions on the first two elements: standard of care and breach. See TEX.
    CIV. PRAC. & REM. CODE § 74.351(r)(6).
    With respect to the Curnels’ claim against Methodist for its allegedly
    inadequate policies, Fomenko opines that the standard of care required the hospital
    to have in place and enforce policies and procedures requiring all physicians,
    nurses, and pharmacists providing care to a patient to evaluate the patient’s
    medications for hepatotoxicity and other negative effects and contraindications
    through in-house computer formulary programs and pharmaceutical publications.
    She further opines that the policies and procedures should require such an
    evaluation to occur when the patient is admitted to the hospital and, once admitted,
    when the patient is prescribed a given medication. According to Fomenko,
    Methodist breached this standard because such policies and procedures were either
    not in place or not enforced, as evidenced by the fact that Curnel’s medications
    9
    Because Fomenko is a registered nurse and not a physician, she is not qualified to
    offer an opinion on causation. See TEX. CIV. PRAC. & REM.
    CODE § 74.351(r)(5)(C).
    24
    were not evaluated for hepatotoxicity when she was admitted to the hospital or
    before the nurses administered nitrofurantoin to her for three consecutive days.
    With respect to the Curnels’ vicarious liability claim based on negligence by
    the Methodist nursing staff, Fomenko opines that the standard of care required the
    nurses to evaluate Curnel’s medications; recognize that nitrofurantoin was
    hepatotoxic      and   thus    contraindicated   given    Curnel’s   elevated      liver
    enzymes; refrain from administering nitrofurantoin to Curnel; notify the ordering
    practitioner, Esantsi, of the reason for their decision; and seek clarification of his
    order.
    According to Fomenko, the nurses breached the standard of care by failing
    to take any of these steps. The nurses failed to evaluate the hepatotoxic potential of
    Curnel’s medications when Curnel presented to the ER or when she was admitted
    to the hospital, and they failed to document the need to perform such an evaluation
    in Curnel’s plan of care. They noted Curnel had been taking nitrofurantoin, but
    they failed to recognize that nitrofurantoin is hepatotoxic and thus failed to clarify
    the contraindicated nitrofurantoin order with Esantsi or any other practitioner. And
    instead of holding the medication, they administered it to Curnel for three
    consecutive days.
    In her reports, Fomenko explains in detail what she believes the standard of
    care required Methodist and its nursing staff to have done under the circumstances
    25
    and what they did instead. 
    Palacios, 46 S.W.3d at 880
    ; see Gardner v. U.S.
    Imaging, Inc., 
    274 S.W.3d 669
    , 671–72 (Tex. 2008) (per curiam) (when health care
    liability claim involves vicarious liability theory, expert report that adequately
    implicates actions of party’s agents or employees is sufficient to implicate party
    itself). We hold that Fomenko’s expert reports provide adequate opinions on the
    standard of care applicable to Methodist and the manner in which the care
    Methodist rendered breached that standard. See TEX. CIV. PRAC. & REM.
    CODE § 74.351(r)(6).
    2.    Sheer’s opinion on element of causation
    We next consider whether Sheer’s reports provide an adequate opinion on
    the third element: causation. In his reports, Sheer opines that, by failing to
    promptly   evaluate    Curnel’s   mediations    and   instead   administering   the
    contraindicated antibiotic for three consecutive days, Methodist and its nursing
    staff deprived Curnel’s physicians of “necessary data and information for making
    the correct diagnosis and considering discharge from the hospital.”
    According to Sheer, had the Methodist nurses complied with the standard of
    care identified by Fomenko, the physicians would have had the benefit of data
    showing a declining trend in Curnel’s liver enzymes, which, in turn, would have
    led them to diagnose her with DILI and discharge her for further monitoring on an
    26
    outpatient basis, thereby avoiding the liver biopsy and the injuries that Curnel
    received from it.
    [A]dministration of the nitrofurantoin to [Curnel] during her
    hospitalization (due to failure to evaluate the hepatotoxic potential of
    the medication) perpetuated the elevated liver enzymes. In reasonable
    medical probability, if the nurses had not administered nitrofurantoin,
    [Curnel]’s liver enzymes would have immediately improved. Thus,
    the nurses’ administration of the drug deprived the physicians of data
    relevant to a diagnosis of probable drug induced liver injury and
    discharge for outpatient monitoring.
    Sheer’s reports about the nurses, like his reports on Esantsi, attempt to show
    proximate cause by explaining a chain of events that begins with the Methodist
    nurses’ failure to evaluate Curnel’s medications and to refrain from administering
    the contraindicated nitrofurantoin and ends with Curnel’s artery being nicked and
    the resulting injuries. And like the alleged negligence of Esantsi, the alleged
    negligence of Methodist and its nursing staff is too attenuated from Curnel’s
    injuries to be considered a substantial factor in bringing those injuries about.
    Curnel’s physicians identified DILI as a potential cause of her elevated liver
    enzymes two days before the biopsy. Ugbarugba and Naygandhi both considered
    DILI a potential cause of Curnel’s elevated liver enzymes, both ordered that Curnel
    stop taking all hepatotoxic medications, and Naygandhi specifically ordered that
    Curnel stop taking nitrofurantoin. Once Curnel stopped taking nitrofurantoin, her
    enzymes began to improve. And, as Sheer states in his reports, by October 12, the
    liver tests showed even “further improvement.” None of Curnel’s physicians
    27
    ordered that the biopsy not take place. The physicians had the information to
    diagnose Curnel with DILI and discharge her from the hospital before the biopsy.
    Instead, armed with the very information that Curnel claims they needed, they
    elected to go forward with the biopsy on its scheduled date. Sheer’s reports do not
    explain how and why additional information from the nurses would have led the
    physicians to cancel the biopsy if the information the physicians already had did
    not or how the nurses “had either the right or the means to persuade” the
    physicians to cancel the biopsy. 
    Zamarripa, 526 S.W.3d at 461
    . Nor do Sheer’s
    reports state that Methodist’s nurses were part of the decision to perform the
    biopsy or its timing. We hold that Sheer’s reports do not adequately address cause-
    in-fact for the claims against Methodist.
    We further hold that Sheer’s reports do not adequately address
    foreseeability, either. They do not explain how and why Methodist’s nurses should
    have anticipated Curnel’s artery being nicked because of either Methodist’s failure
    to implement and enforce policies and procedures requiring the evaluation of
    hepatotoxic medication or the nurses’ failure to evaluate Curnel’s medications for
    hepatotoxicity and to refuse to administer the drug. Thus, we hold that Sheer’s
    reports on Methodist fail to adequately address both components of proximate
    cause.
    28
    D.    Conclusion on adequacy of expert reports
    In sum, we hold that Sheer’s reports on Esantsi provide adequate opinions
    on the standard of care and breach but do not provide an adequate opinion on either
    component of proximate cause. We further hold that Fomenko’s reports on
    Methodist provide adequate opinions on the standard of care and breach but that
    Sheer’s reports on Methodist do not provide an adequate opinion on either
    component of proximate cause. Therefore, the trial court did not abuse its
    discretion in finding the reports inadequate as to both Esantsi and Methodist.
    Accordingly, we overrule the Curnels’ first issue.
    Motions for Extension to Cure
    In their second and third issues, the Curnels contend that the trial court
    abused its discretion by denying their motion for a 30-day extension to cure the
    deficient expert reports and by denying their motion for reconsideration.
    Under the Act, if the plaintiff timely serves an expert report, and the trial
    court concludes that the report is an objective good faith effort to comply with the
    statute but nevertheless deficient in some way, the trial court has the discretion to
    grant the plaintiff one 30-day extension to cure the deficiencies. TEX. CIV. PRAC. &
    REM. CODE § 74.351(c); 
    Mangin, 480 S.W.3d at 705
    –06. The trial court should err
    on the side of granting the extension. Samlowski v. Wooten, 
    332 S.W.3d 404
    , 416
    (Tex. 2011) (Guzman, J., concurring) (“In order to preserve the highest number of
    29
    meritorious claims, trial courts should err on the side of granting claimants’
    extensions . . . .”); see 
    Samlowski, 332 S.W.3d at 411
    (plurality op.) (agreeing with
    concurrence that trial court should err on side of granting extension). And the trial
    court must grant the extension if the deficiencies are curable. 
    Zamarripa, 526 S.W.3d at 461
    .
    The Texas Supreme Court established a “minimal” standard for determining
    whether a deficient report is curable: “a 30–day extension to cure deficiencies in an
    expert report may be granted if the report is served by the statutory deadline, if it
    contains the opinion of an individual with expertise that the claim has merit, and if
    the defendant’s conduct is implicated.” 
    Scoresby, 346 S.W.3d at 557
    .
    We review a trial court’s ruling on motion for an extension to cure a
    deficient expert report for an abuse of discretion. Quintero v. Hous. Methodist
    Hosp., No. 01-14-00448-CV, 
    2015 WL 831955
    , at *2 (Tex. App.—Houston [1st
    Dist.] Feb. 26, 2015, pet. denied) (mem. op.); Henry v. Kelly, 
    375 S.W.3d 531
    , 535
    (Tex. App.—Houston [14th Dist.] 2012, pet. denied).
    The Curnels served Methodist and Esantsi with expert reports before the
    statutory deadline, Methodist and Esantsi filed objections to the reports, and the
    Curnels served Methodist and Esantsi with additional reports in response to the
    objections. As discussed above, despite their deficiencies, these reports contain the
    opinions of qualified experts that the Curnels’ claims had merit and implicated the
    30
    conduct of Methodist and Esantsi; they qualify as objective good faith efforts to
    comply with the statute. See 
    Scoresby, 364 S.W.3d at 557
    .
    The trial court dismissed their claims without affording them an opportunity
    to cure their deficient reports. Part of the purpose of the extension is to afford a
    plaintiff who made a good faith effort the chance to cure a defective report after the
    deficiencies have been identified by the trial court. Given the Supreme Court’s
    minimal standard and the Curnels’ objective good faith efforts, we cannot say that
    the Curnels’ reports were incurable. See 
    Zamarripa, 526 S.W.3d at 461
    .
    Moreover, when the trial court dismissed the Curnels’ claims, it was unclear
    whether the statute required expert reports to address foreseeability, and at least
    two courts of appeals had held that it did not. See Rio Grande Reg’l Hosp. v.
    Ayala, No. 13-11-00686-CV, 
    2012 WL 3637368
    , at *19 (Tex. App.—Corpus
    Christi Aug. 24, 2012, pet. denied) (mem. op.), abrogated by Columbia Valley
    Healthcare Sys., L.P. v. Zamarripa, 
    526 S.W.3d 453
    (Tex. 2017); Adeyemi v.
    Guerrero, 
    329 S.W.3d 241
    , 246 (Tex. App.—Dallas 2010, no pet.). The Texas
    Supreme Court resolved the issue while this appeal was pending when it issued
    Zamarripa and held that an expert report must address both cause-in-fact and
    
    foreseeability. 526 S.W.3d at 460
    . Given this development, the Curnels’ should be
    afforded the opportunity to amend their reports to address foreseeability and to
    cure the other deficiencies identified in this opinion.
    31
    Therefore, we hold that the trial court abused its discretion in denying their
    motion for an extension to cure and motion for reconsideration. Accordingly, we
    sustain the Curnels’ second and third issues.
    Conclusion
    We reverse the trial court’s order and remand for further proceedings.
