MEMORANDUM OPINION2

In this interlocutory appeal, 1 appellant s , George T. Kuhn, M.D., George T. Kuhn M.D., P.A., doing business as Women ’ s Healthcare Associates (“Wom e n ’ s Healthcare”), Paul James, M.D., Metropolitan Houston Surgery Associates, PLLC (“Metropolitan Houston”), Adam Morales, M.D., West Houston Radiology Associates, L.L.P. (“West Houston Radiology”) , and Singleton Associates, P.A., doing business as Radiology Partners Gulf Coast (“Radiology Partners”) (collectively, “appellants”) , challenge the trial court ’ s order overruling their objections and denying their motions to dismiss the health care liability claim s 2 brought against them by appellee, Angie Sam , in her suit for negligence. In multiple issues , appellants contend that the trial court erred in overruling their objections and denying their motions to dismiss Sam ’ s claims against them

- oophorectomy, 5 and a supracervical hysterectomy. 6 T he friable adhesions found during surgery required “sharp and cautery dissection to free the uterus and right [fallopian] tube and ovary for removal.” Sam experienced excessive blood loss due to the adhesions which required an “inter

Soon after su rgery, Sam developed pain, fever, nausea, and vomiting. A computed tomography (“CT”) scan of Sam ’ s abdomen was done on the third day after her surgery. The CT scan showed “a collection of fluid and [a] probable blood clot in [Sam ’ s] pelvis.” A drain was placed by the interventional radiology department , which “noted that 50 cc of brown and bloody fluid was obtained from [Sam ’ s] pelvis at th [e] time.” Sam continued to experience pain and fever and

surgery, she suffered peritonitis and sepsis. Sam ’s condition slowly improved , and she was discharged from St. Joseph Hospital on April 29, 2018. Sam brings health care liability claims against appellant s, alleging that Sam was their patient and appellants had a duty to act as reasonabl y prudent health care providers. Drs. Kuhn, James, and Morales b reached the applicable standards of care required for treating and caring for Sam in many ways, including, but not limited to, failing to recognize her bowel perforation, failing to diagnose her bowel perforation until the sixth day after her initial surgery, and failing to consult about immediately explor ing Sam ’s abdomen to repair her bowel perforation upon i ts diagnosis . Sam also alleges that Wom e n ’ s Healthcare, Metropolitan Houston, West Houston Radiology , and Radiology Partners are vicariously liable for the acts and omissions of Drs. Kuhn, James, and Morales. Sam requests damages for past and future phys ical pain and suffering, past and future mental anguish, past and future physical impairment, past and future medical expenses, past and future disfigurement, loss of earnings, future lost earning capacity, exemplary damages, and interest. To support her c laim, Sam timely served appellants with an initial expert report authored by J.M. Paine, M.D., F.A.C.O.G. 10 Appellants objected to the initial

Sam t imely serve d appellants with a supplemental expert report authored by Dr. Paine. Dr. Paine ’ s supplemental expert report state s that it i s “intended sole [ ly ] to supplement[] [and] not to replace[] [his] prior report.” 12 In his expert report s , Dr. Paine states that he is a licensed physician and is board certified in obstetrics and gynecology. He has been practicing in the field of obstetrics and gynecology fo r thirty

- five years. C urrently , he is a member of the teaching faculty as an associate professor in the department of obstetrics and gynecology at the University of Texas Health Science Center in San Antonio, Texas. In his position as an associate profes sor, he trains residents and students in obstetrics and gynecology. He is also actively practicing medicine in the field of obstetrics and gynecology. Dr. Paine states that he has extensive experience in the field of obstetrics and gynecology, and he has performed thousands of hysterectomies during his career

. He has knowledge of the accepted standards of medical and surgical care required for patients needing hysterectomies. This includes knowledge of the standards of

pre - operative, inter

- operative, and post

- operative care required for patients who have hysterectomies. When Dr. Paine treat s patients requiring hyste rec tomies, he provides
pre - operative, inter

- operative , and post

- operative care to his patients. Post

- operative care includes “following [a] p atient after [a] surgery is complete[] to diagnose and treat any complications that may arise from the surgical procedure.” According to Dr. Paine, this case involves the purported failure of Drs. Kuhn, James, and Morales to appropriately care for and treat Sam after a hysterectomy , and Dr. Paine is familiar with the type of post

- operative care a patient, such as Sam, should receive and how post

- operative complications, like those experienced by Sam, should be managed and treated. In his expert report s , Dr. Paine states that on April 12, 2018, Sam was admitted to St. Joseph Hospital with pelvic pain, uterine fibroids, and a right ovarian cyst. She underwent an exploratory laparotomy, lysis of adhesions, right salpingo

- ooph orectomy, and supracervical hysterectomy. The friable adhesions found during surgery required “sharp and cautery dissection to free the uterus and right [fallopian] tube and ovary [for] removal.” Sam experienced excessive blood loss due to the adhesions which required an “inter

- operative blood transfusion”; thus, “a decision to stop with a supra [ cervical ] hysterectomy was made

. ” Extensive cautery and suturing were required “to obtain hemostasis.” “T he frozen section on8

the ovarian cyst was benign and cy stoscopy was normal prior to [the] closing [ of her] abdomen.” (Internal quotations omitted.) Soon after surgery , Sam developed pain, fever, nausea, and vomiting. A CT scan of Sam ’ s abdomen was done on her third day after her surgery. The CT scan showed “a collection of fluid and [a] probable blood clot in [Sam ’ s] pelvis.” A drain was placed by the interventional radiology department , which “noted that 50 cc of brown and bloody fluid was obtained from [Sam ’ s] pelvis at th [e] time.” Sam continued to expe rience pain and fever and leukocytosis. On the sixth day after her surgery, another CT scan was taken, and it showed “air, fluid, and contrast leakage within the peritoneal cavity.” After Sam was diagnose d with a bowel perforation , “with evidence of wide spread [sic] peritoneal cavity involvement,” a decision was made to treat Sam ’ s condition conservatively by draining the area even though there

was “ fluid and bowel gas

. . . throughout the peritoneal cavity.” This course of treatment continued for the n ext four days, and Sam ’ s condition continued to deteriorate. On the tenth day after her initial surgery, Sam was taken back to the operating room for an exploratory laparotomy, a repair of her bowel perforation, and a diverting ileostomy. The ileostomy was required because of a “ marked inflammatory reaction to bowel leakage ” that had occurred for an extended length of time. Had an exploratory laparotomy and repair of the bowel perforation been9

performed at the time Sam was diagnosed with the b owel perforation, “with evidence of wide spread [sic] peritoneal cavity involvement,” a colostomy 13 would have been possible. After Sam’s second surgery, Sam suffered peritonitis and sepsis. Sam slowly improved and was discharged seventeen days after she was first admitted to the hospital

. As to the standard of care and breach of the standard of care for Dr. Kuhn, Dr. Paine states that bowel injuries , like a bowel perforation, are a well

- known complication of a hysterectomy. On average they occur in one out of every 700 cases. But if a hysterectomy is performed w hen adhesions are present and when an extensive bowel dissection is also required , the rate of bowel injuries increases. A bowel perforation should be diagnosed three days after a hysterectomy. Given the difficulties with Sam ’ s hysterectomy and the extensive bowel dissection that was required during her surgery , Dr. Kuhn , Sam ’ s gynecologist, should have considered and suspected a bowel perforation by the third day after Sam ’ s surgery , when Sam

w as experiencing pain, fever, nausea, and vomiting and a CT scan showed “a collection of fluid and [a] probable blood clot in [her] pelvis.” The standard of care required Dr. Kuhn to suspect , recognize, and diagnose a bowel perforation by the

13 A “colostomy” is “where the bowel is diverted to exit the abdomen. A colostomy bag is then attached that permits the [person] to pass stool into the bag, which must be drained by the [person], instead of the normal waste elimination process.” Cento cor, Inc. v. Hamilton , 310 S.W.3d 476, 481

third day after Sam ’ s initial surgery and it required Dr. Kuhn to take Sam to surgery “to look for and treat the injury

. ” Dr. Kuhn did not do such things, and thus, breached the standard of care. Additionally, on the sixth day after Sam’s surgery, when Sam ’ s bowel perforation was actually diagnosed, the standard of care required Dr. Kuhn to recommend surgery to Sam and to immediately perform surgery to repair the bowel perforat ion . But Dr. Kuhn did not do either of those things. Instead, he decided to “treat [Sam ’ s] condition conservatively,” by draining the fluid that was present

. (Internal quotations omitted.) There is no precedent for “conservative management” of a bowel perforation when there is evidence of bowel contents and gas free in the patient’s periton eal cavity. (Internal quotations omitted.) Dr. Kuhn ’s failure to take any action to repair Sam ’ s bowel perforation , including a failure to consult with someone from general surgery to explore Sam ’s abdomen and repair the bowel perforation , after the bowe l perforation diagnosis on the sixth day following Sam’s initial surgery was a breach of the standard of care . Further, Dr. Kuhn breached the standard of care by wait ing until the tenth day after Sam ’ s initial surgery to return Sam to surgery to repair th e bowel perforation because it should have been repaired immediately upon its diagnosis. As to the standard of care and breach of the standard of care for Dr. James, Dr. Paine states that bowel injuries , like a bowel perforation, are a well

- known11

complication of a hysterectomy. On average they occur in one out of every 700 cases. But if a hysterectomy is performed w hen adhesions are present and when an extensive bowel dissection is also required, the rate of bowel injuries increases. A bowel per foration should be diagnosed three days after a hysterectomy. According to Dr. Paine, Dr. James was the general surgeon

“ following

. . . Sam[] post

- hysterectomy.” Because Dr. James was the general surgeon “following” Sam after her surgery, once Sam ’ s bowe l perforation was diagnosed on the sixth day after her surgery, the standard of care required Dr. James
to immediately act upon the diagnosis by surgically repairing the bowel perforation or at least recommending a surgical repair of the bowel perforation

. But Dr. James did not do so and instead joined in the “conservative” treatment plan with Dr. Kuhn. (Internal quotations omitted.) There is no precedent for “conservative management” of a bowel perforation when there is evidence of bowel contents and ga s free in the peritoneal cavity. (Internal quotations omitted.) By failing to recommend surgical repair of Sam ’ s bowel perforation and by failing to surgically repair the bowel perforation immediately , Dr. James breached the standard of care. Dr. James also breach ed of the standard of care by wait ing until the tenth day after Sam’s initial surgery to return Sam to surgery to repair the bowel perforation because it should have been repaired immediately upon its diagnosis.12

As to the standard of care and br each of the standard of care for Dr. Morales, Dr. Paine states that bowel injuries , like a bowel perforation, are a well

- known complication of a hysterectomy. On average they occur in one out of every 700 cases. But if a hysterectomy is performed when ad hesions are present and when an extensive bowel dissection is also required , the rate of bowel injuries increases. A bowel perforation should be diagnosed three days after a hysterectomy. According to Dr. Paine, Dr. Morales , an interventional radiologist, “drain[ed] the peritoneal cavity” after Sam was diagnose d with a bowel perforation on the sixth day after her surgery . But there is no precedent for “conservative management” of a bowel perforation when there is evidence of bowel contents and gas free in the peritoneal cavity. (Internal quotations omitted.) Based on Sam ’ s diagnosis of a bowel perforation on the sixth day after her surgery , Dr. Morales should have recommended immediate surgical exploration and repair of the bowel perforation

. Dr. Morales did not do this , and thus, breached the standard of care. As to causation, Dr. Paine states that because of the aforementioned breaches by Drs. Kuhn, James, and Morales, Sam ’ s condition worsened and endangered her life. A bowel perforation is a s urgical emergency that requires immediate intervention. Immediate exploration, wash out of the peritoneal cavity, and repair of the bowel perforation is required. Any course of action other than immediate exploration, wash out, and repair, causes worseni ng peritonitis, sepsis, and possibl e13

death. According to Dr. Paine, the physician s ’ failure to timely diagnos e the bowel perforation, decision to pursue “conservative management” of Sam ’ s bowel perforation after it was diagnosed on the sixth day after her initial surgery , failure to recommend surgical exploration and repair of the bowel p erforation upon its diagnosis, failure to immediately repair the bowel perforation upon its diagnosis , and d ecision to delay the repair of Sam’s bowel perforation until th e tenth day after her initial surgery, caused Sam ’ s condition to deteriorate and allowed for the continued leakage of bowel contents into the peritoneal cavity. (Internal quotations omitted.) Without a repair of the b owel perforation, bowel contents continue d to flow into Sam’s peritoneal cavity “with all the bacteria, chemicals[,] and irritants [that] allow[] [ an ] infection to grow and worsen.” Th e bowel leakage caused severe damage to Sam ’ s physiology and permanent residual damage

. And be cause the infection was allowed to grow, this led to a more complicated recovery process for Sam , a longer hospital stay , and long

- term damage . Sam could not recover from the bowel perforation until it was actually repaired. Dr. Paine also explains that d uring the surgery to repair Sam ’ s bowel perforation, a diverting ileostomy had to be performed. According to Dr. Paine, the ileostomy was required because of a marked inflammatory reaction to bowel leakage
f or an extended length of time, i.e., four days a fter the bowel

- perforation diagnosis14

and ten days after Sam ’ s initial surgery . Had the bowel perforation been repaired at the time it was diagnosed, a colostomy would have been possible. Additionally, Dr. Paine s t ates that peritonitis and sepsis , which ar e life

- threatening conditions, can arise from a bowel perforation , and in such cases , they will not be resolved until the bowel perforation is repaired. Here, because of appellants ’ aforementioned breaches, Sam ’ s peritonitis and sepsis grew worse

— which is what happens when an infection is not properly treated and the source of the infection is not appropriately and timely addressed. Dr. Kuhn objected to Dr. Paine ’ s expert report s and requested that Sam ’ s health care liability claim against him be dismissed. 14 Dr. Kuhn asserted that Dr. Paine’s expert reports do not provide a fair summary of the applicable standard of care and do not explain how Dr. Kuhn breached the standard of care. The reports also do not explain how any alleged breach by Dr. K uhn caused or contributed to cause Sam ’ s injury. Dr. James objected to Dr. Paine ’ s expert report s and requested that Sam ’ s health care liability claim against him be dismissed. 15 Dr. James asserted that Dr. Paine’s expert reports do not provide a fair sum mary of the applicable standard of

care and do not inform Dr. James of what he did to breach the standard of care. Dr. Paine ’ s opinion on causation is speculative and conclusory , and the reports do not
state how Dr. James ’ s breach of the standard of care caused Sam harm. Dr. James also asserts that Dr. Paine is not qualified to offer an opinion on the standard of care and causation related to Dr. James. Dr. Morales objected to Dr. Paine ’ s expert report s and requested that Sam ’ s health care liability claim against him be dismissed. 16 Dr. Morales asserted that Dr. Paine is not qualified to offer an opinion o n causation related to Dr. Morales. After Sam responded to appellants ’ objections and motions to dismiss , the trial court overruled appellants ’ objections to Dr. Paine ’ s expert report s and denied appellants ’ motions to dismiss the health care liability claims against them. 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.

Bennett , 256 S.W.3d 806, 811 (Tex. App.

— Houston [14th Dist.] 2008, 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 tria l 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 appellate court would in a similar circumstance. Harris Cty. Hosp. Dist. v. Garrett , 232 S.W.3d 170, 176 (Tex. App.

— Houston [1st Dist.] 2007, no pet.). But a trial court has no discretion in determining what the law is or in applying the law to t he facts. See Walker v. Packer , 827 S.W.2d 833, 840 (Tex. 1992). In conducting our review, we always consider that the Legislature ’ s goal in requiring expert reports i s to deter baseless claims, not block earnest ones. Jackson v. Kindred Hosps. Ltd.

— El Paso 2016, no pet.); see also Scoresby v. Santillan , 346 S.W.3d 546, 554 (Tex. 2011). Under the Texas Medical Liability Act (“TMLA”) , a plaintiff asserting a health care liability claim must timely serve each defendant physician and health17

The expert report must provide a “fair summary” of the expert ’ s opinions on (1) the applicable standard of c are, (2) the manner in which the care rendered by the defendant physician or health care provider failed to meet the standard of care , and (3) the causal relationship between that failure and the injury, harm, or damages claimed.

A “fair summary ” of the expert ’ s opinions means th at, at the least, the report must state more than the expert ’ s mere conclusions as to the standard of care, breach, and causation; it must instead explain the basis of the expert ’ s opinion so as to link the conclusions to the facts of the case. See Jeline k , 328 S.W.3d at 539 ; Wright , 79 S.W.3d at 52. If a plaintiff fails to timely serve an expert report, then, on the motion of a defendant physician or health care provider, the trial court must dismiss the pertinent health care liability claim with prejudic e and award attorney ’ s fees.

But if a plaintiff timely serves an expert report and a defendant physician or health care provider files a motion challenging th e adequacy of that report, then the trial court may only grant the motion “if it appears to the court, after [a] hearing, that the report does not represent an objective good faith effort to comply with the [TMLA ’ s] definition of an expert report.” T EX

An expert report qualifies as an “objective good faith effort” to avoid dismissal if it discusses each element with sufficient specificity so that it (1) informs the defendant physician or health care provider of the specifi c conduct that the plaintiff questions or about which the plaintiff complains and (2) provides a basis for the trial court to conclude that the plaintiff ’ s health care liability claim has merit.

And when the issue of adequacy hinges on an expert ’ s qualifications, the trial court may also consider the “four corners” of the expert ’ s CV. Id. ; Mangin , 480 S.W.3d at 706 . C ourts must v iew the report in its entirety, rather than isolating specific portions or sections, to determine whether it is sufficient

. See Baty , 543 S.W.3d at 694; see, e.g. , Van Ness v. ETMC First Physicians , 461 S.W.3d 140, 144 (Tex. 2015); see also Austin Heart, P.A. v. Webb , 228 S.W.3d 276, 282 (Tex. App.

In reviewing the adequacy of an expert report, a trial court may not consider an expert ’ s credibility, the data relied on by the expert, or the documents that the expert failed to consider at this pre

A. Standard of Care Related to Dr. Kuhn In a portion of his sole issue, Dr. Kuhn argues that Dr. Paine ’ s expert report s do not adequately address the standard of care as it relates to him because the expert reports do not “provide Dr. Kuhn with specific infor mation about what he should have done differently.” Identifying the standard of care in a health care liability claim is critical. Palacios , 46 S.W.3d at 880. To adequately identify the standard of care, an expert report must set forth “specific informa tion about what the defendant [physician] should have done differently.” Abshire v. Christus Health Se. Tex. , 563 S.W.3d 219, 226 (Tex. 2018) (internal quotations omitted). Thus, related to standard of care and22

breach, the expert report must explain what the defendant physician should have done under the circumstances and what the physician did instead. Palacios , 46 S.W.3d at 880; see also Kline v. Leonard , No. 01

(“[A]n expert report must provide a fair summary of the expert ’ s opinion regarding the applicable standard of care and the manner in which the care rendered by the health care provider failed to meet the standard.” (internal quotations o mitted)). It is not sufficient for the expert to simply state that he knows the standard of care and concludes that it was or was not met. Palacios , 46 S.W.3d at 880. As to the applicable standard of care related to Dr. Kuhn, Dr. Paine , in his expert rep ort s , states that bowel injuries, like a bowel perforation, are a well

- known complication of a hysterectomy. On average they occur in one out of every 700 cases. But if a hysterectomy is performed when adhesions are present and when a n extensive bowel di ssection is also required , the rate of bowel injuries increases. A bowel perforation should be diagnosed three days after a hysterectomy. Given the difficulties with Sam ’ s hysterectomy and the extensive dissection that was required during her initial sur gery, Dr. Kuhn, Sam ’ s gynecologist, should have considered and suspected a bowel perforation by the third day after Sam ’ s surgery, when Sam was experiencing pain, fever, nausea, and vomiting and a CT scan showed “a collection of fluid and [a] probable bloo d clot in [her] pelvis.” The standard of care23

required Dr. Kuhn to suspect, recognize, and diagnose a bowel perforation by the third day after Sam ’ s surgery and also required him to take Sam to surgery “to look for and treat the injury.” Additionally, on the sixth day after surgery, when Sam ’ s bowel perforation was actually diagnosed, the standard of care required Dr. Kuhn to recommend surgery to Sam and to immediately perform surgery to repair her bowel perforation. See Baty , 543 S.W.3d at 694 (courts m ust view report in its entirety, rather than isolating specific portions or sections, to determine whether it is sufficient); Webb , 228 S.W.3d at 282 (“The form of the report and the location of the information in the report are not dispositive.”). Dr. Pai ne ’ s statements about the applicable standard of care for Dr. Kuhn are not vague or conclusory. Rather, the expert report s identif y the specific actions that should have been taken by Dr. Kuhn but were not. See Abshire , 563 S.W.3d at 226

We overrule this porti on of Dr. Kuhn ’ s sole issue. B. Causation Related to Dr. Kuhn In the remaining portion of his sole issue, Dr. Kuhn argues that Dr. Paine ’ s expert report s do not adequately addres s causation as it relates to him because the expert reports do not establish a ca usal link between Dr. Kuhn ’ s conduct and Sam ’ s injuries, the reports contain analytical gaps between Dr. Kuhn ’ s alleged breach of the standard of care and Sam ’ s alleged injury, and Dr. Paine ’ s causation opinion is conclusory.

– 60 (Tex. 2017). An expert report need not marshal all the plaintiff ’ s proof necessary to establish causation at trial, and it need not anticipate or rebut all possible defensive26

theories that may ultimately be presented to the trial co urt. Wright , 79 S.W.3d at 52; Cornejo v. Hilgers , 446 S.W.3d 113, 123 (Tex. App.

. But an expert cannot simply opine that the breach caused the injury. Jelinek , 328 S.W.3d at 539. Causation consists of two components: (1) cause - in

- fact and (2) foreseeability. Gunn v. McCoy , 554 S.W.3d 645, 658 (Tex. 2018). A defendant physician ’ 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 the harm would not have occurred. Id. Even if the harm would not have occurred absent the defendant physician ’ s breach, “the connection between the defendant and the plaintiff ’ s 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) (internal quotations omitted). A brea ch is not a substantial factor if it “does no more than furnish the condition that makes the plaintiff ’ s injury possible.” Id. A defendant physician ’ s breach is a foreseeable cause of the plaintiff ’ s injury if physician of ordinary intelligence would hav e anticipated the danger caused by the negligent act or omission. Puppala , 564 S.W.3d at 197. As to standard of care and breach of the standard of care, Dr. Paine , in his expert report s , state s that bowel injuries, like a bowel perforation, are a well

- known complication of a hysterectomy. On average they occur in one out of every 70027

cases. But if a hysterectomy is performed when adhesions are present and when an extensive bowel dissection is also required , the rate of b owel injuries increases. A bowel perforation should be diagnosed three days after a hysterectomy. Given the difficulties with Sam ’ s hysterectomy and the extensive dissection that was required during her initial surgery, Dr. Kuhn, Sam ’ s gynecologist, shou ld have considered and suspected a bowel perforation by the third day after Sam ’ s surgery, when Sam was experiencing pain, fever, nausea, and vomiting and a CT scan showed “a collection of fluid and [a] probable blood clot in [her] pelvis.” The standard o f care required Dr. Kuhn to suspect, recognize, and diagnose a bowel perforation by the third day after Sam ’ s surgery and take Sam to surgery “to look for and treat the injury.” Dr. Kuhn , by not doing either of those things, breached the standard of care. Additionally, on the sixth day after her initial surgery, when Sam ’ s bowel perforation was actually diagnosed, the standard of care required Dr. Kuhn to recommend surgery to Sam and to immediately perform surgery to repair the bowel perforation. But Dr. Kuhn did not do either of those things. Instead, he decided to “treat [Sam ’ s] condition conservatively,” by draining the fluid that was present. There is no precedent for “conservative management” of a bowel perforation when there is evidence of bowel co ntents and gas free in the peritoneal cavity. (Internal quotations omitted.) Dr. Kuhn ’s failure to take any action to repair Sam ’ s bowel perforation, including his failure to consult with someone from general surgery to28

explore Sam ’s abdomen and repair the bowel perforation , after the bowel perforation diagnosis on the sixth day following Sam’s initial surgery was a breach of the standard of care. Further, Dr. Kuhn breached the standard of care by waiting until the tenth day after Sam ’ s init ial surgery to return Sam to surgery to repair the bowel perforation because it should have been repaired immediately upon its diagnosis. As to causation, Dr. Paine, in his expert report s , states that because of the aforementioned breaches by Dr. Kuhn, Sam ’ s condition worsened and endangered her life. Dr. Paine explained that a bowel perforation is a surgical emergency that requires immediate intervention. Immediate exploration, wash out of the peritoneal cavity, and repair of the bowel perforati on is required. Any course of action other than immediate exploration, wash out, and repair, causes worsening peritonitis, sepsis, and possibl e death. According to Dr. Paine, Dr. Kuhn ’ s failure to timely diagnos e the bowel perforation, decision to pursue “conservative management” of
Sam ’ s bowel perforation after it was diagnosed on the sixth day after her initial surgery, failure to recommend surgical exploration and repair of the bowel perforation upon diagnosis, failure to not immediately repair the bow el perforation upon diagnosis, and decision to delay the repair of Sam’s bowel perforation until the tenth day after her initial surgery , caused Sam ’ s condition to deteriorate and allowed for the continued leakage of bowel contents into the peritoneal cavi ty. (Internal quotations omitted.) Without a repair of Sam’s bowel perforation, bowel contents29

continued to flow into Sam ’ s peritoneal cavity “with all the bacteria, chemicals[,] and irritants [that] allow[] [ an ] infection to grow and worsen.” The bowel leakage caused severe damage to Sam ’ s physiology and permanent residual damage. And because the infection was allowed to grow, this led to a more complicated recovery
process for Sam, a longer hospital stay, and long

- term damage. Sam could not recover f rom the bowel perforation until it was actually repaired. Further, during the surgery to repair Sam ’ s bowel perforation, a diverting ileostomy had to be performed. According to Dr. Paine, the ileostomy was required because of a marked inflammatory reaction to bowel leakage for an extended length of time, i.e., four days after the bowel

- perforation diagn osis and ten days after Sam ’ s initial surgery. Had the bowel perforation been repaired at the time it was diagnosed, a colostomy would have been possible. Dr. Paine also explain s that peritonitis and sepsis, which are life

- threatening conditions, can aris e from a bowel perforation, and in such cases, they will not be resolved until the bowel perforation is repaired. Here, because of Dr. Kuhn ’ s aforementioned breaches, Sam ’ s peritonitis and sepsis grew worse

— which is what happens when an infection is not p roperly treated and the source of the infection is
not appropriately and timely addressed. Sam ’ s condition worsened and endangered her life

In determining whether an expert ’ s causation opinion is conclusory, we must remain mindful that expert

- report chal lenges are made at an early, pre

- discovery stage in the litigation, not when the merits of the health care liability claim are being presented to the fact finder to determine liability. Puppala , 564 S.W.3d at 198. To provide more than a conclusory statem ent on causation, an expert report must include an “explanation tying the conclusion to the facts” and showing “how and why the breach caused the injury based on the facts presented.” Jelinek , 328 S.W.3d at 539

– 40; see also Puppala , 564 S.W.3d at 197. Th e expert report need only provide some basis that the defendant physician ’ s act or omission proximately caused injury. Owens v. Handyside , 478 S.W.3d 172, 187

. . . [T]he information in the report does not have to meet the same requirements as the evidence offered in a summary

- judgment proceeding or at trial ”). Here, Dr. Paine ’ s causation opinion is in line with those found sufficient in other health

- care - liability cases at th is stage of the litigation where experts have opined that had the defendant physician not breached the standard of care, a proper diagnosis and medical intervention would have been achieved and the plaintiff ’ s injury, harm, or damages would have been avoided.

Thus, we hold that the trial court did not err in overruling Dr. Kuhn ’ s objections and denying Dr. Kuhn’s motion to dismiss Sam ’ s health care liability claim against him on the ground that Dr. Paine ’ s expert reports do not adequately address causation as to Dr. Kuhn

. § 74.401. Dr. Paine has extensive experience in the field of obstetrics and gynecology, and he has performed thousands of hysterectomies during his career. He has knowledge of the accepted standards of medical and surgical care required for patients needing hysterectomies. This includes knowledge of the standards of
pre - operative, inter

- operative, and post

- oper ative care required for patients who have hysterectomies. When Dr. Paine treats patients requiring hysterectomies, he provides
pre - operative , inter

- operative, and post

- operative care to his patients. Post

- operative care includes “following [a] patient aft er [a] surgery is complete[] to diagnose and treat any complications that may arise from the surgical procedure.” T his case involves the purported failure of appellants, including Dr. James, to appropriately care for and treat Sam after a hysterectomy, an d Dr. Paine is familiar with the type of post

- operative care a patient, such as Sam, should receive and how post

- operative41

complications, like those experienced by Sam, should be managed and treated. See Broders , 924 S.W.2d at 15 2

. . . is to give an opinion”); Baylor Univ. Med. Ctr. v. Biggs , 237 S.W.3d 909, 916 (Tex. App.

— Dallas 2007, pet. denied) ( “[T]he focus is on the fit between the subject matter at issue and the exp ert ’ s familiarity with it, not on a comparison of the expert ’ s title or specialty with that of the defendant

. . . . ” (internal quotations omitted) ) ; see also Owens , 478 S.W.3d at 186

– 87 (specific issue in case was whether defendant physicians failed to ti mely and appropriately diagnose and treat plaintiff ’ s condition and expert report showed that expert had experience treating patients with condition suffered by plaintiff and he was familiar with the standard of care applicable to physician s who care for p atients with same condition with which plaintiff presented). We note that a s to the standard of care and breach of the of the standard of care for Dr. James, Dr. Paine, in his expert reports, states that bowel injuries, like a bowel perforation, are a well

- known complication of a hysterectomy. On average they occur in one out of every 700 cases. But if a hysterectomy is performed when

a dhesions are present and when an extensive bowel dissection is also required , the rate of bowel in

juries increases. A bowel perforation should be diagnosed three days after a hysterectomy.42

According to Dr. Paine, Dr. James was the general surgeon “following

. . . Sam[] post

- hysterectomy.” Because Dr. James was the general surgeon “following” Sam afte r her surgery, once Sam ’ s bowel perforation was diagnosed on the sixth day after her surgery, the standard of care required Dr. James to act upon the diagnosis by surgically repairing the bowel perforation immediately

or at least recommending surgical repa ir of the bowel perforation. But Dr. James did not do so, and instead joined in the “conservative” treatment plan with Dr. Kuhn. (Internal quotations omitted.) There is no precedent for “conservative management” of a bowel perforation when there is evid ence of bowel contents and gas free in the peritoneal cavity. (Internal quotations omitted.) By failing to recommend surgical repair of Sam ’ s bowel perforation and by failing to surgically repair the bowel perforation immediately, Dr. James breached the standard of care. Further, Dr. James breached t he standard of care by waiting until the tenth day after Sam’s initial surgery to return Sam to surgery to repair the bowel perforation because it should have been repaired immediately upon its diagnosis.
Her e, w e conclude that Sam has met her burden of establishing that Dr. Paine is qualified to offer an opinion on the standard of care related to Dr. James. See T EX

The Texas Supreme Court has cautioned reviewing courts from drawing expert qualifications too narrowly, as Dr. James has requested us to do in this case, and we re emphasize t hat a proffered expert need not practice in the same specialty as the defendant physician to qualify as an expert in the case. See Larson v. Downing , 197 S.W.3d 303, 305 (Tex. 2006); Roberts v. Williamson , 111 S.W.3d 113, 122 (Tex. 2003) ; see also Owens , 478 S.W.2d at 186 ; Blan , 7 S.W.3d at 745 (g eneral surgeon qualified to testify about standard of care for post

- operative procedures performed by gynecologist because post

- operative procedures are common to both fields ). We hold that the trial court did not err in overruling Dr. James ’ s objection s and denying Dr. James’s motion to dismiss Sam ’ s health care liability claim against him on the ground that Dr. Paine is not qualified to offer an opinion on the standard of care related to Dr. James. We overrule th is portion of Dr. James ’ s sole issue.44

B. Dr. Paine ’ s Qualification s Related to Causation In a nother portion of his sole issue, Dr. James argues that Dr. Paine is not qualified to offer an opinion on causation related to Dr. James because Dr. Paine ’ s expert report s and CV do not show that Dr. Paine has “ experience in handling patients with peritonitis and sepsis secondary to a bowel perforation” or that he has the qualifications “to opine on the cause of [Sam ’ s] alleged damages” and the ramifications of the “ alleged four[

- ]day delay in [the] surgical repair of [Sam ’ s] bowel per foration.” To be qualified to opine on the causal relationship between a defendant physician ’ s alleged failure to meet an applicable standard of care and the plaintiff ’ s claimed injury, harm, or damages, the author of an expert report must be a physician

w ho is qualified to render opinions on such causal relationships under the Texas Rules of Evidence. See T EX

. § 74.403(a); see id. § 74.351(r)(5)(C) (“ [e] xpert” means “with respect to a person giving opinion testimony about the c ausal relationship between the injury, harm, or damages claimed and the alleged departure from the applicable standard of care in any health care liability claim, a physician who is otherwise qualified to render opinions on such causal relationship under t he Texas Rules of Evidence” (internal quotations omitted)); Cornejo , 446 S.W.3d at 120.45

An expert witness may be qualified on the basis of knowledge, skill, experience, training, or education to testify on scientific, technical, or other specialized subjec ts if the testimony would “assist the trier of fact” in understanding the evidence or determining a fact issue. Cornejo , 446 S.W.3d at 121 (internal quotations omitted); see T EX

. Thus, a plaintiff must show that h er expert has “knowledge, s kill, experience, training, or education” about the specific issue before the court that would qualify the expert to give an opinion on that particular subject. Broders , 924 S.W.2d at 153

– 54 (internal quotations omitted); see also Cornejo , 446 S.W.3d at 121. Not every licensed physician is qualified to testify on every medical question. See Broders , 942 S.W.2d at 152

– 53; Cornejo , 446 S.W.3d at 121. Yet, a physician need not practice in the particular field about which he is testifying so long as he can demonstrate that he has knowledge, skill, experience, training, or education about the specific issue before the court that would qualify him to give an opinion on that subject. Cornejo , 446 S.W.3d at 121. Simply put , what is required is that t he physician demonstrate that he is qualified to opine on the specific issue before the
court. Puppala , 564 S.W.3d at 202. Here it is a sserted that Dr. James was the general surgeon “following

. . . Sam[] post

- hysterectomy.” Because Dr. James was the gen eral surgeon “following” Sam after her surgery, once Sam ’ s bowel perforation was46

diagnosed on the sixth day after her surgery, Dr. James should have acted upon the diagnosis by surgically repairing the bowel perforation immediately or at least recommending surgical repair of the bowel perforation. Instead, Dr. James joined in the “conservative” treatment plan with Dr. Kuhn, although there is no precedent for “conservative management” of a bowel perforation when there is evidence of bowel contents and gas f

ree in the peritoneal cavity. (Internal quotations omitted.) By failing to recommend surgical repair of Sam ’ s bowel perforation and by failing to surgically repair the bowel perforation immediately, Dr. James breached the standard of care. Dr. James als o breached the standard of care by waiting until the tenth day after Sam’s initial surgery to return Sam to surgery to repair the bowel perforation because it should have been repaired immediately upon its diagnosis. It is also a sserted that Dr. James ’ s br each es of the standard of care caused Sam ’ s condition to worsen and endangered her life. A bowel perforation is a surgical emergency that requires immediate intervention. Immediate exploration, wash out of the peritoneal cavity, and repair of the bowel p erforation is required. Any course of action other than immediate exploration, wash out, and repair, causes worsening peritonitis, sepsis, and possible death. Dr. James ’ s failure to recommend surgical exploration and repair of Sam ’ s bowel perforation upo n its diagnosis, to not immediately repair the bowel perforation upon its diagnosis , and to not repair Sam ’ s bowel perforation until the tenth day after her initial surgery caused Sam ’ s condition47

to deteriorate and allowed for the continued leakage of bowel contents into the peritoneal cavity. Without a repair of Sam’s bowel perforation, bowel contents continued to flow into Sam’s peritoneal cavity “with all the bacteria, chemicals[,] and irritant s [that] allow[] [ an ] infection to grow and worsen.” The bowel leakage caused severe damage to Sam ’ s physiology and permanent residual damage, and it allowed for Sam ’ s peritonitis and sepsis to grow worse. And because Sam ’ s infection was allowed to grow, this led to a more complicated recovery process for Sam, a longer hospital stay, and long

- term damage. Sam could not recover from the bowel perforation until it was actually repaired. Further, during the surgery to repair Sam ’ s bowel perforation, a diver ting ileostomy had to be performed. The ileostomy was required because of a marked inflammatory reaction to bowel leakage for an extended length of time, i.e., four days after the bowel

- perforation diagnosis and ten days after Sam ’ s initial surgery. Had the bowel perforation been repaired at the time it was diagnosed, a colostomy would have been possible. Sam ha s the burden of establishing that Dr. Paine ha s “knowledge, skill, experience, training, or education” about whether Dr. James ’ s breach es of the

s tandard of care

by failing to recommend surgical exploration and repair of Sam ’ s bowel perforation upon its diagnosis, not immediately repair ing the bowel perforation upon its diagnosis, and not repair ing Sam ’ s bowel perforation until the48

– 60. An expert report need not marshal all the plaintiff ’ s proof n ecessary 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; Cornejo , 446 S.W.3d at 123. But an expert cannot simply opine that the breach caused the injury. Jelinek , 328 S.W.3d at 539. Causation consists of two components: (1) cause - in

- fact and (2) foreseeability. McCoy , 554 S.W.3d at 658. A defendant physician ’ s breach was

a cause - in

- fact of the plaintiff ’ s injury if the brea ch was a substantial factor in bringing about the harm, and absent the breach the harm would not have occurred. Id. Even if the harm would not have occurred absent the defendant physician ’ s breach, “the connection between the defendant and the plaintiff ’ s injuries simply may be too attenuated” for the breach to qualify as a substantial factor. Allways Auto Grp. , 530 S.W.3d at 149 (internal quotations omitted). 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 defendant physician ’ s breach is a foreseeable cause of the plaintiff ’ s injury if a physician of ordinary intelligence would have anticipated the dan ger caused by the negligent act or omission. Puppala , 564 S.W.3d at 197.53

As to standard of care and breach of the standard of care related to Dr. James , Dr. Paine , in his expert report s , state s that bowel injuries, like a bowel perforation, are a well

- kno wn complication of a hysterectomy. On average they occur in one out of every 700 cases. But if a hysterectomy is performed w hen adhesions are present and when an extensive bowel dissection is also required , the rate of bowel injuries increases.
Because Dr. James was the general surgeon “following

. . . Sam[] post

- hysterectomy,” once Sam ’ s bowel perforation was diagnosed on the sixth day after surgery, the standard of care required Dr. James to act upon the diagnosis by surgically repairing the bowel per foration immediately or at least recommend ing surgical repair of the bowel perforation. But James did not do so. Instead, he joined in the “conservative” treatment plan with Dr. Kuhn. (Internal quotations omitted.) There is no precedent for “conservative management” of a bowel perforation when there is evidence of bowel contents and gas free in the peritoneal cavity. (Internal quotations omitted.) By failing to recommend surgical repair of Sam ’ s bowel perforation and failing to surgically repair the bowel perforation immediately after its diagnosis , Dr. James breached the standard of care. Dr. James also breached the standard of care by waiting until the tenth day after Sam’s initial surgery to return Sam to surge ry to repair the bowel perforation because it should have been repaired immediately upon its diagnosis.54

As to causation, Dr. Paine, in his expert report s , states that because of the aforementioned breaches of the standard of care by Dr. James , Sam ’ s condit ion worsened and endangered her life. Dr. Paine explained that a bowel perforation is a surgical emergency that requires immediate intervention. Immediate exploration, wash out of the peritoneal cavity, and repair of the bowel perforation is required.
A ny course of action other than immediate exploration, wash out, and repair, causes worsening peritonitis, sepsis, and possibl e death. According to Dr. Paine, Dr.
James ’ s failure to recommend surgical exploration and repair of Sam ’ s bowel perforation upon its diagnosis, to not surgically repair the bowel perforation immediately upon its diagnosis, and to not repair Sam ’ s bowel perforation until the tenth day after her initial surgery caused Sam ’ s condition to deteriorate and allowed for the continued leakag e of bowel contents into the peritoneal cavity. Without a repair of Sam’s bowel perforation, bowel contents continued to flow into Sam ’ s peritoneal cavity “with all the bacteria, chemicals[,] and irritants [that] allow[] [ an ] infection to grow and worsen.” The bowel leakage caused severe damage to Sam ’ s physiology and permanent residual damage. And because the infection was allowed to grow, this led to a more complicated recovery process for Sam, a longer hospital stay, and long

- term damage. Sam could not recover from the bowel perforation until it was actually repaired.55

Further, during the surgery to repair Sam ’ s bowel perforation, a diverting ileostomy had to be performed. According to Dr. Paine, the ileostomy was require d because of a marked inflammatory reaction to bowel leakage for an extended length of time, i.e., four days after the bowel

- perforation diagnosis and ten days after Sam ’ s initial surgery. Had the bowel perforation been repaired at the time it was diagnos ed, a colostomy would have been possible. Dr. Paine also explains that peritonitis and sepsis, which are life

- threatening conditions, can arise from a bowel perforation, and in such cases, they will not be resolved until the bowel perforation is repaired. Here, because of Dr. James ’ s breaches of the standard of care, Sam ’ s peritonitis and sepsis grew worse

— which is what happens when an infection is not properly treated and the source of the infection is not appropriately and timely addressed. Sam ’ s condit ion worsened and endangered her life

. In determining whether an expert ’ s causation opinion is conclusory, we must remain mindful that expert

- report challenges are made at an early, pre

- discovery stage in the litigation, not when the merits of the health care liability claim are being presented to the fact finder to determine liability. Puppala , 564 S.W.3d at 198. To provide more than a conclusory statement on causation, an expert report must simply include an “explanation tying the conclusion to the facts” and showing “how and why the breach caused the injury based on the facts presented.” Jelinek , 328 S.W.3d56

at 539

– 40; see also Puppala , 564 S.W.3d at 197. The expert report need only provide some basis that the defendant physician ’ s act or omission proximately caused injury. Owens , 478 S.W.3d at 187

– 88; see also Palacios , 46 S.W.3d at 879 (explaining “a plaintiff need not present evidence in the report as if it were actually litigating the merits.

. . . [T]he information in the re port does not have to meet the same requirements as the evidence offered in a summary

- judgment proceeding or at trial”). Here, Dr. Paine ’ s causation opinion is in line with those found sufficient in other health

- care - liability cases at this stage of the li tigation where experts have opined that had the defendant physician not breach ed the standard of care, a proper diagnosis and medical intervention would have been achieved and the plaintiff ’ s injury, harm, or damages would have been avoided. See, e.g. , Wh itmire , 2020 WL 4983321, at *15

– 16; Puppala , 564 S.W.3d at 198

– 202 ; Owens , 478 S.W.3d at 187

– 91. An expert may show causation by explaining a chain of events that begins with the defendant physician ’ s negligence and ends in injury to the plaintiff. See Whitmire , 2020 WL 4983321, at *16; Owens , 478 S.W.3d at 189; McKellar , 367 S.W.3d at 485

Dr. Paine ’ s expert report s explain57

the connection between Dr. James ’ s alleged negligent cond uct and the claimed injury, harm, or damages. See Tiscareno , 495 S.W.3d at 614 (“[T]he expert must at a minimum explain the connection between [the physician’s ] conduct and the injury to the patient.”); see also Whitmire , 2020 WL 4983321, at *16; Owens , 4 78 S.W.3d at 189 (expert may show causation by explaining chain of events that begins with defendant physician ’ s negligence and ends in injury to plaintiff); McKellar , 367 S.W.3d at 485

– 86. Finally, we note that Dr. James asserts that Dr. Paine ’ s expert re ports do not establish that without Dr. James ’ s purported negligence “Sam ’ s outcome would have been any different.” B ut an expert report need not address all hypothetical scenarios.
See Whitmire , 2020 WL 4983321, at *16; Garcia , 2009 WL 3223178, at *6. And although the law requires an expert report to link the expert ’ s conclusion on causation with the alleged breach of the standard of care, nothing requires the expert report to address or rule out all other possible scenarios. See Whitmire , 2020 WL 4983321, at *16; Garcia , 2009 WL 3223178, at *6; see also Owens , 478 S.W.3d at 187 (report “need not anticipate or rebut all possible defensive theories that may ultimately be presented” in case)

We conclude that the trial court could have reasonably determined that Dr. Paine ’ s expert reports represent a n “objective good faith effo rt” to inform Dr. James of the causal relationship between Dr. James ’ s purported failure to provide care in accord with the appliable standard of care and the claimed injury, harm, or damages.

to Dr. James and Dr. Paine’s expert reports do not adequately address causation as it relates to Dr. James. In her petition, Sam alleges that Metropolitan Houston is vicariously liable for the conduct of Dr. James. Generally, when a plainti ff brings health care liability claims against more than one defendant physician or health care provider , the expert report must set forth the standard of care and breach of the standard of care as to each defendant and explain the causal relationship betw een each defendant ’ s individual acts or omissions and the claimed injury.

Yet, when a plaintiff brings a health care liability claim based on a vicarious liability theory against a defendant health care provider, an expert report that adequately implicates the actions of that party’s agent or employee is sufficient as to the defendant health care provider.

To preserve a co mplaint for appellate review, the record must show that the complaint was made to the trial court by a timely request, objection, or motion and the trial court either ruled on the party ’ s request, objection, or motion, or refused to rule, and the party obj ected to that refusal.

Dr. Paine ’ s Qualification s to Opine on Causation In the remaining portio n of his sole issue, Dr. Morales argues that Dr. Paine is not qualified to offer an opinion on causation related to Dr. Morales because Dr. Paine “does not address his experience in caring for patients with peritonitis and sepsis secondary to a bowel perfo ration” and Dr. Paine ’ s expert report s and CV “do not reflect qualifications allowing him to opine o n the ca u se of [Sam ’ s] alleged damages” or the ramifications of the “ alleged four [

- ] day delay in [the] surgical repair of [Sam’s] bowel perforation.” To be qualified to opine on the causal relationship between a defendant physician’s alleged failure to meet an applicable standard of care and the plaintiff ’ s claimed injury, harm, or damages, the author of an expert report must be a physician who is qualified to render opinions on such causal relationships under the Texas Rules of Evidence.

. § 74.403(a); see id. § 74.351(r)(5)(C) (“ [e] xpert” means “with respect to a person giving opinion testimony about the causal relationship between the injury, harm, or damages claimed and the alleged departure from the applicable standard of care in any health care liability claim, a physician who is otherwise qualified to render opinions on65

An expert witness may be qualified on the basis of knowledge, skill, experience, training, or education to testify on scientific, technical, or other special ized subjects if the testimony would “assist the trier of fact” in understanding the evidence or determining a fact issue.

Here , it is a sserted that Dr. Morale s “drain[ed] the peritoneal cavity” after Sam was diagnosed with a bowel perforation on the sixth day after her initial surgery. Yet, there is no precedent for “conservative management” of a bowel perforation when there is evidence of bowel contents and g as free in the peritoneal cavity. (Internal quotations omitted.) Based on Sam ’ s diagnosis of a bowel perforation on the sixth day after her surgery, Dr. Morales should have recommended immediate surgical exploration and repair of the bowel perforation. Dr. Morales did not do this , and thus, breached the standard of care. It is also a sserted that Dr. Morales ’ s breach of the standard of care caused Sam ’ s condition to worsen and endangered her life. A bowel perforation is a surgical emergency that requires immediate intervention. Immediate exploration, wash out of the peritoneal cavity, and repair of the bowel perforation is required. Any course of action other than immediate exploration, wash out, and repair, causes worsening peritonitis, sepsis, and pos sible death. Dr. Morales ’ s failure to recommend surgical exploration and repair of Sam ’ s bowel perforation upon its diagnosis caused Sam ’ s condition to deteriorate and allowed for the continued leakage of bowel contents into the peritoneal cavity. Withou t a repair of Sam’s bowel perforation, bowel contents continued to flow into Sam’s peritoneal cavity “with all the bacteria, chemicals[,] and irritants [that] allow[] [ an ] infection to grow and worsen.” The bowel leakage caused severe damage to Sam ’ s phys iology and permanent residual damage , and it67

allowed for Sam ’ s peritonitis and sepsis to grow worse. And because Sam ’ s infection was allowed to grow, this led to a more complicated recovery process for Sam, a longer hospital stay, and long

- term damage. Sam could not recover from the bowel perforation until it was actually repaired. Further, during the surgery to repair Sam ’ s bowel perforation, a diverting ileostomy had to be performed. The ileostomy was required because of the marked inflammato ry reaction to bowel leakage for an extended length of time, i.e., four days after the bowel

- perforation diagnosis and ten days after Sam ’ s initial surgery. Had the bowel perforation been repaired at the time it was diagnosed, a colostomy would have been possible. Sam ha s the burden of establishing that Dr. Paine ha s “knowledge, skill, experience, training, or education” about whether Dr. Morales ’ s breach of the standard of care

—

by failing to recommend immediate surgical exploration and repair of the bowel perforation upon its diagnosis on the sixth day after Sam’s
surgery

— caused Sam ’ s claimed injury, harm, or damages. See Brooks , 2017 WL 127867, at *6 (internal quotations omitted) ; Vora , 473 S.W.3d at 869

– 70; see also Cornejo , 446 S.W.3d at 121 (plaintiff s required to establish expert qualified on basis of knowledge, skill, experience, training, or education to offer opinion concerning causal link between alleged breaches of standard of care and injuries suffered) ;68

. In his expert report s , Dr. Paine states that he is a licensed physician and is board certified in obstetrics and gynecology. He has been practic ing in the field of obstetrics and gynecology fo r thirty

- five years. Currently, he is a member of the teaching faculty as an associate professor in the department of obstetrics and gynecology at the University of Texas Health Science Center in San Antonio. In his position as an associate professor, he trains residents and students in obstetrics and gynecology, Dr. Paine is actively practicing medicine in the field of obstetrics and gynecology , and he was practicing medicine at the time Sam ’ s claims arose. Dr. Paine has extensive experience in the fiel d of obstetrics and gynecology, and he , as part of his medical practice, has performed thousands of hysterectomies during his career. He has knowledge of the accepted standards of medical and surgical care required for patients needing hysterectomies. Th is includes knowledge of the standards of pre

- operative, inter

- operative, and post

- operative care required for patients who have hysterectomies. When Dr. Paine treats patients requiring hysterectomies, he provides
pre - operative, inter

- operative, and post

- operative care to his patients. Post

- operative care includes “following [a] patient after [a] surgery is complete[] to diagnose and69

treat any complications that may arise from the surgical procedure.” This case involves the purported failure of appellant s, including Dr. Morales, to appropriately care for and treat Sam after a hysterectomy, and Dr. Paine is familiar with the type of post

- operative care a patient, such as Sam, should receive and how post

- operative complications, like those experienced by Sa m, should be managed and treated. We conclude that Dr. Paine ’ s expert report s and CV demonstrate that he is qualified to offer an opinion on the causal link between Dr. Morales ’s alleged breach while providing post

- operative care after Sam ’ s hysterectomy a nd Sam ’ s injuries, harm, and damages. See Jassin , 2012 WL 5974020, at * 5 (“ We cannot say that the trial court abused its discretion in

. . . finding that Dr. Branch is qualified to provide an expert report on causation for the complications that allegedly arose from Dr. Jassin ’ s post

- operative care following a sinus surgery that Dr. Branch says he has performed approximately 200 times, along with providing the follow

- up care for those surgeries .”); Chavez , 2007 WL 59513 4, at *3

. Further, because Dr. Morales did70

not dispute in the trial court that Dr. Paine i s qualified to offer an opinion on the standard of care as to Dr. Morales, it would have be en reasonable for the trial court
to have c onclude d that Dr. Paine is qualified to offer an opinion on Dr. Morales’s

We hold that the trial court did not err in overruling Dr. Morales ’ s objections and denying Dr. Morales’s motion to dismiss Sam ’ s health care liability claim against him on the ground that Dr. Paine is not qualified to offer an opinion on causation related to Dr .
