——————————— MOHAMMAD KHAN, M.D., Appellant V. JOHN RAMSEY AND JENN IFER RAMSEY, Appellee s

On Appeal from the 23rd District Court Brazoria County , Texas Trial Court Ca u se No. 638042 MEMORANDUM OPINION In this interlocutory appeal, 1 appellant, Dr. Mohammad Khan, M.D., challenges the trial court ’ s order denying his motion to dismiss the health care liability claim 2 made against him by appellees, John Ramsey and Jennifer Ramsey, in their suit for negligence. In his sole issue, Khan contends that the trial court
erred in not dismissing the Ramseys’ claim. We affirm. Background In their original petition, the Ramseys assert a he alth care liability claim against Dr. Khan, Dr. O

. C

. Oandasan, M.D., and IPH Home Health Care Services,
Inc

. (“IPH”) , alleging that John was hospital ize d on March 30, 2009 for a “suspected stroke

. ” He was ultimately diagnosed with endocarditis, an infecti on of the heart characterized by heart

- valve vegetation growth. On April 9, John underwent “mitral valve surgical debridement” to repair and remove the “vegetation which had grown on his mitral valve.” Khan discharged John on April
14 , with follow

- up tre atment to be administered by his primary care physician, Oandasan. From April 14 to April 24, John received treatment at his home from

. § 51.014(a)(9) (Vernon Supp. 2012).

2 See id. § 74.001(a)(13) (Vernon Supp. 2012).3 IPH, which administered to h im two “potent” antibiotics: vancomycin and
g entamycin. During this time, John “developed signs and symptoms of severe antibiotic overdose,” but IPH “did not take action as required by the standard of care for a home health network.” Although IPH “did attempt to communicate information” to Oandasan about John’s condition , Oandasan “either failed to review” or “ignored” the information. By April 24, the level s of vancomycin and gentamycin in John’s system

were “off the chart,” his renal function was “severely compromised,” and he felt “lethargic with a cough and fever.” I PH staff contacted an on

- call doctor for Dr. Oandasan, Dr. Bui, who warned that John “should go to the emergency room ‘or he would die.’” John , who was ultimately diagnosed with Stevens

- Johnson Syndrome , lapsed into a coma and had to undergo years of trea tment and therapy. As a result of the incident, he is “totally disabled” with “persistent vertigo from vestibular damage, left side weakness, cognitive disorder, memory loss, tinnitus, migraine headache syndrome, depression, and other issues all arising f rom the antibiotic overdose.” The Ramseys allege that Dr. Khan and Dr. Oandasan “deviated from the standard of care for physicians” in their treatment of Ramsey. The Ramseys specifically allege that Khan: 1) failed to communicate abnormal lab results to [Oan dasan] and the patient; [and]4 2) failed to develop, arrange for and assure that a definitive plan was put in place to oversee the administration and monitoring of vancomycin and gentamycin by IV treatment of [John].
T he Ramseys further allege that Khan’s “de viations from the standard of care,” in addition to those of Oandasan and IPH, were “the proximate cause of the severe iatrogenic antibiotic toxicity which resulted in [his] permanent injury and disability.” The Ramseys attached to their petition an expert report 3 authored by Dr. Charles J. Chitwood, M.D., a practicing physician. In the section of his report entitled, “Qualifications,” Chitwood notes that he is board certified in Family
Medicine , wo rks in a “large Community Medical Center’ s Department of F amily Medicine, ” has practiced a “full range of family medicine , ” and ha s treated “many patients over the years with endocarditis (both native and artificial valves).” He explains that he has “always handled the diagnosis, work

- up, treatment and follow

up of serious infectious disease cases with the highest of priority.” Based on these and other q ualifications, Chitwood asserts that he was “qualified to review and prepare an expert opinion re garding this case.”

3 See id. § 74.351 (Vernon 2011) (requiring expert report to be served in health care liability claims).5 In his report, Dr. Chitwood notes that John was first admitted into
emergency care on March 19, 2009, exhibiting symptoms that “painted a worrisome picture for endocarditis.” However, he was released on oral antibiotics, including vanc omycin, with no diagnosis of endocarditis

. The physician ordered the pharmacy “‘to manage Vancomycin,’ indicating an understanding of the meticulous care required when overseeing this drug with multiple pot ential serious side effects.” Subsequently, o n Ma rch 30, after a follow

- up examination, John was referred to Dr. Khan , who performed tests on John that rev ealed “mitral valve vegetations. ” Khan began a “bro ad

- spectrum antibiotic regiment, ” and, o n April 9,
John underwent mitral valve surgical debridemen t to remove the heart valve vegetation. He was discharged on April 14 “with a plan for long

- term v ancomycin and gentamycin” as recommended by the hospital’s Infectious Disease Consultant, Dr. Farooq.
Dr. Chitwood notes that Dr. Khan provided an “addendum to the discharge summary . . . months after [John’s] release,” which he read as an “attempt to underscore all of the risks and concerns that should have been addressed in April. ” Chitwood explains that on April 10, Dr. Far ooq stopped treating John with

v a ncomycin due to “metabolic/allergic concerns

. ” Nevertheless, Khan prescribed

v ancomycin for John four days later , upon his discharge . Chitwood could see no “rationale” for the change in John’s medication

. From April 14 to April 24, John6 was under the care of IPH , which administered v ancomycin and gentamycin intravenously pursuant to the hospital discharge plan. During this time, John developed symptoms of antibiotic overdose. When Joh n began exhibiting symptoms of v ancomycin and gentamycin overdose, IPH could not contact Dr. Khan because it had “the wrong contact points.” A resident nurse , in a n “addendum progress note , ” wrote that “multiple attempts to notify [ Dr. Oandasan] of treatment and lab results were unsuccessful. [Oandasan] stated to notif y Dr. Khan or Dr. McFadden. Dr. Khan when contacted stated to notify [Oandasan].” Ultimately, an on

- call doctor advised IPH personnel to transport John to an emergency room. On April 24, John was readmitted to the hospital with symptoms of an allergic reaction to the prescribed antibiotics and antibiotic overdose. His lab results demonstrated “severe antibiotic toxicity , ” and his levels for vancomycin and gentamycin were “astronomically ‘off the chart’ in fatal toxicity regions.” John was then determi ned to be in critical condition and diagnosed with Stevens

- Johnson Syndrome. In regard to the standard of care applicable to Dr. Khan, Dr. Chitwood explains that “the discharge is a period of transition from hospital to home that involves a transfer in res ponsibility from the hospitalist to the patient and primary care physician.” He explains that Khan “should have gone out of his way in APRIL to make sure continuity and prudent care was arranged.” Chitwood notes7 that the standard of care required Khan “t o develop a definitive plan for transition from hospital to home healthcare , ” which would “include discharge instructions for the patient of the myriad risks and potential complications of long term potential damage from intravenous gentamycin and vancomyc in use.” However, Khan’s discharge summary “ did not mention ” the se facts “until an addendum was written
MONTHS after the damage had been done and appears as an attempt to shift blame to the patient after the fact.” Chitwood opine s that Khan breached the standard of care by failing to properly transition care to Dr. Oanda san, the primary care physician; “assure that arrangements were made for follow

- up, monitoring and feedback, given the dangers inherit” in using gentamycin and vancomycin; and

“ communicate the abnormal lab results ” from April 10 “ to both the patient and Dr. Oandasan.”
In his first amended answer, Dr. Khan generally denied the Ramseys’ allegations and asserted that “the incident in issue was caused, in whole or in part, by perso ns, entities, or factors” beyond his control and John’s injuries resulted
from “pre

- existing conditions and disabilities, and/or the result of intervening new and independent causes.” Khan objected to Dr . Chitwood’s expert report and moved to dismiss 4 the Ramseys’ claims against him, arguing that the report

4 See id. § 74.351(a).8 constituted “no report” because Chitwood failed to show that he is qualified to render an opinion as to Khan’s standard of care, identify the standard of care, or state how Khan breached the standard of care. In their response , the Ramseys asserted that Chitwood’s report is adequate . They attached to their response an amended report, along with a request for a 30

- day extension 5 to file the amended report, “[s]hould any aspect of [the] initial report be found inadequate.” After a hearing, the trial court granted the Ramsey’s request for a 30

- day extension to file the amended report. Dr. Khan filed a second motion to dismiss, raising the same objections to the amended report as in his previous motion to
dismiss and asserting that the second report “singularly and/or in combination with the earlier filed report . . . still fail [ed] to meet the requirements of Chapter 74 of the Texas Civil Practice and Remedies Code with respect to h ospi talist, Mohammad Khan, M.D. ” The trial court denied Khan’s motion

. 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. Pal acios , 46 S.W.3d 873, 875 (Tex. 2001); Gray v. CHCA Bayshore L.P. ,

5 See id. § 74.351(c). In their brief, the Ramseys’ assert that Dr. Khan did not oppose their request for a 30

- day extension.9 189 S.W.3d 855, 858 (Tex. App.

— Houston [1st Dist.] 2006, no pet.). A trial court abuses its discretion if it acts in an arbitrary or unreasonable manner without reference to guiding rules or principles. Jelinek v. Casas , 328 S.W.3d 526, 539 (Tex. 2010) . When reviewing matters committed to the trial court’s discretion, we may not substitute our own judgment for that of the trial court. Bowie Mem’l Hosp. v. Wright , 79 S.W.3d 48, 52 (Tex. 2002) . A trial court does not abuse its discret ion merely because it decides a discretionary matter differently than an appellate court would in a similar circumstance. Harris County Hosp. Dist. v.

— Houston [1st Dist.] 2007, no pet.)

. Sufficiency of Expert Report
In his sole issue, Dr. Khan argues that the trial court erred in denying his motion to dismiss the Ramseys’ health care liability claim because Dr. Chitwood “lacks the expertise to provide opinions on the standard of care, breach and causation with respect to” Khan. He also asserts that Chitwood’s expert report is “conclusory” as to the applicable standard of care and the alleged breach of the standard of care and “wholly fail[s] to address causation.” A health care liability claim ant must timely provide each defendant health

care provider with an expert report

. § 74.351 (Vernon 2011 ); Gray , 189 S.W.3d at 858

The expert report must provide a fair summary of the expert ’ s opinions as of the date of the report regarding the10 applicable standards of care, the manner in which the care rendered by the health care provider failed to meet the standards, and the causal relationship between th at failure and the injury, harm, or damages claimed.

. If a defendant files a motion to dismiss challenging the adequacy of the

. First, the report must inform the defendant of the sp ecific conduct the claimant has called into question. Id. Second, the report must provide a basis for the trial court to conclude that the claim has merit. Id. A repor t that merely states the expert’ s conclusions does not fulfill these two purposes. Id. The expert must explain the basis of his statements to link his conclusions to the facts. Bowie ,11 79 S.W.3d at 52. However, a claimant need not present evidence in the report as if he were actually litigating the merits. Palacios , 46 S.W.3d at 879. Furthermore, the report may be informal in that the information in the report need not meet the same requirements as th e evidence offered in a summary

- judgment proceeding or trial. Id. Qualifications Dr. Khan first asserts that Dr. Chitwood “does not possess special knowledge regarding the specific matter on which he is offering an opinion” and is “not qualified to provide an opinion . . . on the basis of training or experience.” In regard to an “ expert report ” in a health care liability claim, an “expert,” “giving opinion testimony about the causal relationship between [an] injury, harm, or damages claimed and [an] alleged departure from the applicable standard of care,” must be “a physician who is otherwise qualified to render opinions on such causal relationship under the Texas Rules of Evidence.” T EX

On the issue of whether a physician departed from accepted standards of medical care, a person may qualify as an expert witness only if the person is a physician who: (1) is practicing medicine at the time such testimony is given or was practicing medicine at the time the claim arose; (2) has knowledge of accepted standards of medical care for the diagnosis, care, or treatment of the illness, injury, or condition involved in the claim; and (3) is qualified on the basis of training or experience to offer an expert opinion regarding those accepted standards of medical care.

Dr. Khan argues that Dr. Chitwood “does not possess special knowledge regarding the specific matter on which he is offering an opinion” because Khan “is an internal medicine specialist who was practicing as a hospitalist” and Chitwood is a family practice physician. Khan further argues that because Chitwood “has never practiced as a hospitalist , ” he “is not qualified to state what the sta ndard of care required of Dr. Khan, a hospitalist, regarding the discharge arrangements.” Courts of appeals have recognized that an expert witness need not be a specialist in the particular branch of the medical profession for which the testimony is offere d

. Id. ; Blan v. Ali , 7 S.W.3d 741, 745

– 46 (Tex. App.

— Houston [14th Dist.] 1999, no pet.). Here, in his expert report, Dr. Chitwood a sserts that Dr. Khan breached the pertinent standard of care by failing “to develop a definitive plan for transition from hospital to home healthcare,” such as including “discharge instructions for the patient” concerning the risks associated with the antibiotics he was taking. Chitwood also assert s that Khan breached the pertinent standard of care by failing14 to “ assure that arrangements were made for follow

- up, monitoring and feedback” and “communicate the abnormal lab results to both the patient and Dr. Oandasan.” He further explains that, I have personally supervised the medical management of multiple patients with infectious endocarditis, to include developing the treatment plan, ordering, administering and monitoring intravenous antibiotics and writing the detailed home health discharge and fol low

up schedules. I have always handled the diagnosis, work

- up, treatment and follow

- up of serious infectious diseases with the highest of priority.
Because Dr. Chitwood has over eighteen years of medical experience, including ambulatory, urgent, and eme rgent care , he possesses specialized knowledge on “subject matter [that] is common to and equally recognized and developed in all fields of practice,” such as hospital discharge , recognizing the importance of patient history, and the infection process , all of which are addressed
in his report. See Keo , 76 S.W.3d at 732 ; Hersh v. Hendley , 626 S.W.2d 151, 155 (Tex. Civ. App.

— Fort Worth 1981, no writ ) ( labeling “ taking a medical history ” and “ discharge before complete recovery ” as “acts related to practices which are commonly and equally recognized in all fields of practice” ) ; Garza v. Keillor , 623 S.W.2d 669, 671 (Tex. Civ. App.

— Houston [14th Dist.] 1981, writ ref ’ d n.r.e.) ( “[T]he standard of care in the infection process . . . is common to and equal in all fields of medical practice” ).15 Additionally, Dr. Chitwood possesses specialized knowledge particular to John ’s treatment. In his report, Chitwood indicates that he has “supervised the medical management of many patients with infectious endocarditis, ” for which John was originally hospitalized

. Chitwood’s medical management included developing treatment plans ; ordering, administering, and monitoring intravenous
antibiotics ; and writing detailed home health discharge plan s with follow

- up schedules. The R amseys’ claim involves each of these areas of experience. Chitwood’s experience also includes consulting with home health companies for patient needs, including the administration of long

- term intravenous antibiotics. This claim also involves the coordination between a doctor and a home health services company regarding the dispensation of antibiotics intravenously. Thus , the trial court could have reasonably conclude d that Chitwood “ has knowledge of accepted standards of medical care for the diagnosis, care, or treatment of the illness, injury, or condition involved in [this] claim .” See T EX
. C IV
. P RAC
. & R EM
. C ODE A NN . § 74.401(a)

. In regard to Dr. Chitwood’s “training or experience,” we consider “ whether, at the tim e the claim arose or at the time the testimony is given, the witness .

. . (1) is certified by a licensing agency . .

. in the area of health care relevant to the claim; and (2) is actively practicing medicine in rendering medical care services relevant to the claim.” See id. § 74.401(c)

. Here, i t is undisputed that Chitwood is16 currently licensed by the Texas State Board of Medical Examiners in Family Medicine and currently pr actices “in a large Community Department of Family
Medicine

. ” And, as stated above, Chitwood possesses specialized experience relevant to this claim

. Chitwood indicates that , “ as a Board Certified, independent staff physician ” with “over 18 years of ambu latory, urgent and emergent care experience,” he has experie nce with treating endocarditis, including “developing the treatment plan, ordering, administering and monitoring intravenous antibiotics and writing the detailed home health discharge planning and follow

- up schedules.” Thus, t he trial court could have reasonably concluded that Chitwood has established his qualifications to render opinions regarding the standard of care, alleged breach of the standard of care, and causation under section 74.351. Accordingly, we hold that the trial court did not err in denying Dr. Khan’s motion to dismiss the Ramseys’ health care liability claim on the ground that Dr. Chitwood is not qualified to render his opinion. Standard of Care and Breach Dr. Khan next asserts that the standard of care articulated in Dr. Chitwood’s expert report is “conclusory ,” “ contradictory to the facts as stated , ” and “fail[s] to identify what actions were required for Dr. Khan to comply with the standard of
care.” He further as serts that the expe rt report is “conclusory” as to the alleged17 breach of the standard of car e and “not based upon what [ Chitwood] claims was the standard of care.” Identifying the standard of care in a health care liability claim is critical: whether a defendant brea ched his or her duty to a patient cannot be determined absent specific information about what the defendant should have done differently. Palacios , 46 S.W.3d at 880. While a “fair summary” is something less than a full statement of the applicable standard of care and how it was breached, even a fair summary must set out what care was expected, but not given. Id

. When a plaintiff

sues more than one defendant, the expert report must set forth the standard of care for each defendant and explain the causal rela tionship between each defendant’ s individual acts and the injury. See Doades v. Syed , 94 S.W.3 d 664, 671

– 72 (Tex. App.

— San Antonio 2002, no pet.); Rittmer v. Garza , 65 S.W.3d 718, 722 (Tex. App.

— Houston [14th Dist.] 2001, no pet.)

. Dr. Khan argues that Dr. Chitwood ’s report is conclusory because he does not thoroughly define “definitive plan,” “fail[s ] to state what the potential complications and myriad risks that were supposed to be stated in the discharge instructions,” and does not state when the discharge instructions “ must be prepared and/or if this information could be verbally communicated to t he patient and still meet the standard of care.” Khan asserts that the report does not specify “what he was required by the standard of care to do.”18 In his report, Dr. Chitwood explains , The standard of care called for Dr. Khan to develop a definitive pl an for transition from hospital to home healthcare. Such a plan would include discharge instructions for the patient of the myriad risks and potential complications of long term potential damages from intravenous gentamycin and vancomycin use. The physicia n discharge summary did not mention these facts until an addendum was written MONTHS after the damage had been done

. . . . In addition Dr. Khan should have arranged for an orderly transition of care to the primary physician by contact with Dr. Oandasan to assure that arrangements were made for follow

- up, monitoring and feedback, given the dangers inherit in using these antibiotics. Dr. Khan breached the standard of [care] in failing to assure that such a transition to Dr. Oandasan was accomplished and in fa iling to communicate the abnormal lab results to both the patient and Dr. Oandasan. The pertinent standard of care identified by Chitwood required that Dr. Khan “develop a definitive plan for transition from hospital to home healthcare.” Chitwood specifies that this plan sh ould have include d communicating , in the hospital discharge instructions , the specific risks associated with John’s prescribed medication. As noted in Chitwood’s report, the specific risks associated with

v ancomycin toxicity are renal side effects, nervous system damage , hematologic complications, and “ red man syndrome , ” among others

. Chitwood further identifie s Khan’s fail ure to comply with the standard of care , noting that Khan ’s addendum to the discharge instructions was not created until “MONTHS a fter the damage had been done.” Chitwood also specifies that Khan’s plan for transition from hospital to home healthcare should have included arranging contact with Dr.19 Oandasan to “ assure ” “ follow

- up, monitoring, and feedback ,” giv en the known danger s of the prescribed drugs

. Thus, the trial court could have reasonably conclude d that Dr. Chitwood’s report represents a “good faith effort” to inform Dr. Khan of the specific conduct called into question, the standards of care that should have been followed, and what he should have done differently

. Accordingly, we hold that the trial court did not err in denying Khan ’s motion to dismiss the Ramseys’ health ca re liability claim on the ground that Chitwood ’ s expert report fail s to identify the pertinent standard s of care and breach of those standards

. Causation Finally, Dr. Khan argues that Dr. Chitwood “ wholly fail[s] to address causation ” because his report “merely state[s] conclusions regarding what proximately caused the injury.” As noted above, an expert report must provide a fair summary of the expert ’ s opinions regarding the causal relationship between the failure of the health care provider to provide care in accord with the pertinent standard of care and the injury, harm, or damages claimed.

. § 74.351(r)(6). In support of his argument, Dr. Khan relies on Bowie Memorial Hosp ital v. Wright , 79 S.W.3d 48 (Tex. 2002). In Bowie , the pla intiff alleged that a physician’ s assistant misread or misplaced an x

- ray and, therefore, did not discover20 that the plaintiff had fractured her foot. Id. at 50. Approximately one month later, the plaintiff’ s orthopedic surgeon discovered the fracture. Id. The plaintiff filed the report of an expert , who stated that had the x

- ray been properly read, she “would have had the possibility of a better outcome.” Id. at 51. The court, after recognizing that a re port need not use any particular phrase , held that the trial court could have reasonably determined that the report did not represent a good

- faith effort to summarize the causal relationship. Id. at 53. The court noted that the report simply opined that the plaintiff had a “possibility of a better outcome,” and did not sufficiently “[link] the expert’ s conclusion (that [the plaintiff] might have
had a b etter outcome) to [the hospital’ s] alleged breach (that it did not correctly read and act upon the x

- ray s).” Id. Here, in contrast, Dr. Chitwood opine s in his expert report that , “[i]n all reasonable medical probability, with proper oversight, early detection and response in this case, even as conducted, [John] would not have suffered any of the severe medi cal maladies resulting from his antibiotic toxicity.” He also states that Dr. Khan ’s breach of the standard of care “[was] the cause in the delayed diagnosis and this delay was the proximate cause of the certainty of permanent disability and need for extensive treatment described herein. ” He continues , “I believe within a reasonable degree of medical certainty that the above described delays, oversight and submaximal care caused [John’s] . . . damages.” See Linan v. Rosales , 15521 S.W.3d 298, 305

– 06 (Tex. App.

— El Paso 2004, pet. denied) (affirming verdict in favor of plaintiff for doctor’ s fai lure to timely diagnose cancer); In re Barker , 110 S.W.3d 486, 491 (Tex. App.

— Amarillo 2003, orig. proceeding ) ( concluding expert report sufficient i n stating that negligent failure to recognize medical condition and delay in treatment increased severity of plaintif f’ s injuries).
In his report , Dr. Chitwood indicate s that Dr. Khan failed to develop a discharge plan to include communication of the specific risks associated with

v ancomycin toxicity, including renal side effects, nervous system damage, hematologic complications, “ red man syndrome, ” and Stevens

- Johnson S yndrome, among others. John actually suffered from renal side effects, nervous syst em damage, hematologic complications, “ red man syndrome, ” and Stevens

- Johnson
S yndrome. In Chitwood’s professional opinion , John suffered these effects “due to a failure of recognition and treatment.” He opines that “[i]n all reasonable medical probabili ty, with proper oversight, early detection and response in this case, even as conducted, [John] would not have suffered any of the severe medical maladies resulting from his antibiotic toxicity.” Chitwood provides a fair summary of his opinion that Khan f ailed to meet the standard of care in managing John’s discharge from his care and transition to home health, exacerbated by failing to make contact with Dr. Oandasa n. He then opin es with “proper oversight,” John would not have suffered the effects of anti biotic toxicity. Thus, Chitwood has provided Khan a fair22 summary of his opinion as to how Khan ’s improper patient management and oversight caused John’s adverse reactions

. The trial court could have reasonably
conclude d that Chitwood , in his report, made a “good faith effort” to provide a fair summary of the causal relationship between Khan ’s failure to meet the pertinent standard s of care and John’s injury

. Accordingly, we hold that the trial court did not err in denying D r. Khan ’s motion to dismiss the Ramseys’ health care liability claim on the ground that their expert report does not address causation

. We overrule Dr. Khan ’s sole issue. Conclusion We affirm the order of the trial court.
