Reyes vs. Sisters of Mercy Hospital

A physician is not liable for medical malpractice absent competent expert proof that the diagnosis or treatment fell below the reasonable average standard of care exercised by ordinarily prudent practitioners under similar circumstances; the doctrine of res ipsa loquitur does not operate to dispense with expert testimony when the injury or death involves the merits of a diagnosis or a scientific treatment whose propriety is not obvious to a layperson.

Jorge Reyes had been suffering from recurring fever with chills for five days before his admission. Home medication with analgesic, antipyretic, and antibiotics provided no relief. Typhoid fever was then prevalent in the locality, with the clinic receiving 15 to 20 cases monthly. On January 8, 1987, his wife brought him to the Mercy Community Clinic, where respondent physicians attended to him and ultimately administered intravenous chloromycetin after a Widal test indicated typhoid fever. He died in the early morning of January 9, 1987. His family thereafter instituted a damage suit grounded on alleged negligence in diagnosis and treatment.

• The Parties: Petitioner Leah Alesna Reyes is the widow of Jorge Reyes; the other petitioners are their children. Respondents are the Mercy Community Clinic, its directress Sister Rose Palacio, and attending physicians Dr. Marlyn Rico and Dr. Marvie Blanes.
• Medical History and Admission: Jorge Reyes suffered recurring fever with chills for five days prior to admission and obtained no relief from self-administered analgesic, antipyretic, and antibiotics. On January 8, 1987, he was taken to the Mercy Community Clinic by his wife. At admission, he was conscious, ambulatory, oriented, coherent, but with respiratory distress.
• Initial Diagnosis by Dr. Marlyn Rico: Dr. Rico, the admitting physician, took his medical history and performed a physical examination. Noting that typhoid fever was prevalent (15 to 20 cases per month at the clinic), she ordered a Widal test, blood count, urinalysis, stool examination, and malarial smear. The Widal test results, available after about an hour, showed a ratio of 1:320. Dr. Rico concluded Jorge was positive for typhoid fever. As her shift ended at 5:00 p.m., she indorsed the patient to Dr. Marvie Blanes.
• Treatment by Dr. Marvie Blanes: Dr. Blanes examined Jorge at around 6:00 p.m., took his history, and likewise formed the impression of typhoid fever. She ordered a compatibility test for the antibiotic chloromycetin (chloramphenicol). Nurse Josephine Pagente performed a skin test and observed no adverse reaction. At around 9:00 p.m., Dr. Blanes ordered the intravenous administration of the first 500 mg dose of chloromycetin. A second 500 mg dose was administered approximately three hours later, just before midnight.
• Deterioration and Death: At around 1:00 a.m. of January 9, 1987, the patient’s temperature rose to 41°C, and he experienced chills, respiratory distress, nausea, vomiting, and convulsions. Dr. Blanes placed him under oxygen, used a suction machine, and administered hydrocortisone, which temporarily eased the convulsions. Upon regaining consciousness, the patient denied any prior heart ailment or chest pains. After about 15 minutes, vomiting and convulsions returned; valium was administered, but the patient did not respond and slipped into cyanosis. He died at approximately 2:00 a.m. The recorded cause of death was “Ventricular Arrythemia Secondary to Hyperpyrexia and typhoid fever.”
• Autopsy by Petitioners’ Expert: Dr. Apolinar Vacalares, Chief Pathologist at the Northern Mindanao Training Hospital, performed an autopsy on January 9, 1987, but did not open the skull. He found the gastro-intestinal tract normal, without ulceration or enlargement of nodules. He opined that Jorge did not die of typhoid fever but of “shock undetermined,” possibly due to allergic reaction or chloromycetin overdose. He testified he had never performed an autopsy on a typhoid victim and had treated only about three typhoid cases clinically, way back before his training.
• Respondents’ Expert Testimony: Dr. Peter Gotiong, a diplomate in internal medicine specializing in microbiology and infectious diseases, who had treated over a thousand typhoid cases, testified that with a 1:320 Widal test result and the patient’s history, typhoid fever would be the primary impression. He stated chloromycetin was the drug of choice and that complications such as toxic myocarditis and toxic meningitis could occur despite treatment. He explained that intestinal hyperplasia in typhoid may be microscopic and that a proper autopsy should have included brain examination. Dr. Ibarra Panopio, a member of the American Board of Pathology and an experienced pathologist, stated that while he preferred the culture test, the Widal test was also used; a 1:320 ratio was already the maximum for a conclusive impression, and no further information could be gained from higher dilutions. He corroborated that hyperplasia could be microscopic and that the danger in typhoid lay in its complications.
• Procedural Agreement: At pre-trial, the parties limited the issues to whether Jorge’s death was caused by respondents’ negligence, whether the clinic was negligent in hiring, and the entitlement to damages.

• Application of Res Ipsa Loquitur: Petitioners argued that all requisites for res ipsa loquitur were present: an accident that does not ordinarily occur absent negligence; the instrumentality causing injury was under respondents’ exclusive control; and the injury was not due to the patient’s voluntary act. They contended that Jorge, merely suffering from fever and chills, was conscious and ambulant at admission yet died only ten hours later, making negligence self-evident without need for expert testimony.
• Misdiagnosis and Negligent Prescription: Petitioners maintained that Dr. Rico hastily relied on the Widal test, erroneously diagnosed typhoid fever, and immediately prescribed chloromycetin without sufficient compatibility testing. They asserted that the true cause of death was anaphylactic shock or chloromycetin overdose, not typhoid fever.
• Negligent Administration of Second Dose: Petitioners claimed that Dr. Blanes was negligent in ordering the second 500 mg dose of chloromycetin barely three hours after the first, when the standard interval should have been five to six hours, as allegedly directed by Dr. Rico.
• Standard of Care — Extraordinary Diligence: Petitioners contended that the medical profession, analogous to common carriers, is imbued with public interest and that physicians should be held to the same standard of extraordinary diligence imposed by Article 1733 of the Civil Code on common carriers.
• Alleged Lower Standard of Medical Practice: Petitioners argued that the Court of Appeals committed reversible error by assuming that the level of medical practice is lower in Iligan City, thereby applying a reduced standard of care and diligence to the respondent physicians.

• Proper Diagnosis and Standard Procedure: Respondents countered that Dr. Rico’s diagnosis of typhoid fever was based on standard medical procedure: the patient’s history, prevalent local incidence of the disease, and a Widal test result of 1:320, which expert witnesses confirmed as sufficient to indicate typhoid. The Widal test, though not conclusive, was recognized as a normal diagnostic tool.
• Appropriateness of Chloromycetin and Dosage: Respondents argued that chloromycetin was the drug of choice for typhoid fever, the intravenous route was correct, and the total dosage of 1 gram within a few hours was still within medically acceptable limits, as the recommended dose was 1 gram every six hours. They pointed out that skin testing for haptenic drugs is generally not reliable in ruling out anaphylactic sensitivity, so a negative skin test did not guarantee absence of reaction.
• Lack of Competent Contrary Expert Evidence: Respondents maintained that petitioners’ expert, Dr. Vacalares, was not qualified to testify on typhoid diagnosis and treatment because he was neither a specialist in infectious diseases nor experienced in typhoid cases. Their own experts, Dr. Gotiong and Dr. Panopio, were eminently qualified and established that the standard of care was met.
• Rejection of Res Ipsa Loquitur: Respondents asserted that the doctrine did not apply because the patient’s death involved matters of medical diagnosis and scientific treatment not within the common knowledge of laypersons. The pre-existing serious condition of the patient precluded an inference of negligence from the mere fact of death.

• Res Ipsa Loquitur: Whether the doctrine of res ipsa loquitur was applicable to dispense with expert testimony and permit an inference of negligence from the circumstances of Jorge Reyes’ death.
• Negligence in Diagnosis and Treatment: Whether respondent physicians breached the standard of care by diagnosing typhoid fever based on the Widal test and by administering two doses of 500 mg chloromycetin within a three-hour interval.
• Standard of Care Required of Physicians: Whether physicians are bound by the extraordinary diligence standard imposed on common carriers under Article 1733 of the Civil Code.
• Alleged Assumption of Lower Medical Standard: Whether the Court of Appeals erred by assuming a lower level of medical practice in Iligan City and thereby applying a diminished standard of care.

• Res Ipsa Loquitur: The doctrine of res ipsa loquitur was correctly rejected. Although the patient died only hours after admission, his death was not an occurrence that, as a matter of common knowledge, implies negligence. He had been suffering recurring fevers and chills for five days unrelieved by home medication, indicating a serious illness for which professional help came late. The alleged failure to observe due care involved the merits of a diagnosis and scientific treatment, matters not immediately apparent to a layman. As held in Ramos v. Court of Appeals, res ipsa loquitur has no application to suits challenging the correctness of a diagnosis or the result of a scientific treatment; it is restricted to situations where a layman can say that the consequences ordinarily would not have followed if due care had been exercised.
• Negligence in Diagnosis and Treatment: The allegation of specific negligent acts was not proven. Petitioners’ purported expert, Dr. Vacalares, was not qualified to testify on the diagnosis of typhoid fever; he was not a specialist in infectious diseases, had never performed an autopsy on a typhoid victim, and had treated only three typhoid cases long before his training. His opinion was therefore inadmissible. In contrast, respondents’ experts, Dr. Gotiong and Dr. Panopio, were specialists whose testimony established that the Widal test was a standard diagnostic tool for typhoid, that a 1:320 result plus the patient’s history and local disease prevalence sufficiently supported the diagnosis, and that chloromycetin was the drug of choice. The two 500 mg intravenous doses administered within three hours remained within medically acceptable limits because the recommended dosing was 1 gram every six hours. Further, even if the patient suffered anaphylactic shock, skin testing for haptenic drugs is not reliably predictive, and the law requires only that physicians perform standard tests and procedures, not predict all possible reactions. The burden of proving that Jorge suffered from another illness or that respondents deviated from the standard of care rested with petitioners, and they failed to present competent expert evidence to meet it.
• Standard of Care Required of Physicians: Physicians are not held to the extraordinary diligence standard imposed on common carriers by Article 1733 of the Civil Code. The practice of medicine is a profession subject to rigorous state regulation, licensure, and ethical standards under the Hippocratic Oath. The standard applicable to physicians is reasonable diligence — the reasonable average merit among ordinarily good physicians practicing under similar circumstances and in the same or similar locality. There is no need to superimpose an extraordinary diligence requirement.
• Alleged Assumption of Lower Medical Standard: The Court of Appeals made no unfounded assumption that medical practice is inferior in Iligan City. Its reference to the standard of care being that of a physician in the “same or similar locality” merely articulated the established locality-based standard in medical negligence cases. The ruling applied the correct legal standard of reasonable skill and competence expected of practitioners in comparable communities, not a diminished one.

• Res Ipsa Loquitur in Medical Malpractice — The doctrine permits an inference of negligence without expert testimony only when the injury is of a kind that does not ordinarily occur absent negligence, the instrumentality causing injury was under the exclusive control of the defendant, and the injury was not due to the plaintiff’s voluntary act. It is applied with caution and is generally restricted to cases where a layperson, from common knowledge and observation, can say that the consequences of professional care were not such as would ordinarily follow if due care had been exercised. The doctrine has no application to suits challenging the merits of a medical diagnosis or a scientific treatment, where the propriety of the physician’s judgment is not apparent to a non-expert.
• Standard of Care for Physicians — A physician is bound to exercise that degree of care and skill which is ordinarily employed by the profession generally, under similar conditions, and in like surrounding circumstances. The standard is not the highest possible level of skill nor the average of all practitioners from best to worst, but the reasonable average merit among ordinarily good physicians. The extraordinary diligence standard prescribed for common carriers does not apply to the medical profession.
• Expert Testimony in Medical Malpractice — To establish breach of the standard of care and proximate causation, expert testimony is generally indispensable because the matters involved are determinable only in light of scientific knowledge. The testimony must come from a witness qualified as an expert in the relevant specialty; a physician lacking specialization or substantial experience in the particular field of diagnosis or treatment involved cannot competently opine on whether the standard of care was breached.
• Elements of Medical Malpractice — A patient alleging medical negligence must prove four elements: (1) the existence of a physician-patient relationship giving rise to a duty; (2) breach of that duty by failing to act as a reasonably prudent physician would or by doing what a reasonably prudent physician would not do; (3) injury to the patient; and (4) proximate causation between the breach and the injury suffered.

• “Res ipsa loquitur is not a rigid or ordinary doctrine to be perfunctorily used but a rule to be cautiously applied, depending upon the circumstances of each case. It is generally restricted to situations in malpractice cases where a layman is able to say, as a matter of common knowledge and observation, that the consequences of professional care were not as such as would ordinarily have followed if due care had been exercised. A distinction must be made between the failure to secure results, and the occurrence of something more unusual and not ordinarily found if the service or treatment rendered followed the usual procedure of those skilled in that particular practice. It must be conceded that the doctrine of res ipsa loquitur can have no application in a suit against a physician or a surgeon which involves the merits of a diagnosis or of a scientific treatment.”
• “The standard contemplated is not what is actually the average merit among all known practitioners from the best to the worst and from the most to the least experienced, but the reasonable average merit among the ordinarily good physicians.”
• “The law cannot require [physicians] to predict every possible reaction to all drugs administered. The onus probandi was on the appellants to establish, before the trial court, that the appellee-physicians ignored standard medical procedure, prescribed and administered medication with recklessness and exhibited an absence of the competence and skills expected of general practitioners similarly situated.”

• Ramos v. Court of Appeals, G.R. No. 124354, December 29, 1999 — The Court relied on this case as the controlling precedent on the application of res ipsa loquitur in medical malpractice suits. It was distinguished: in Ramos, brain damage during a routine cholecystectomy was an occurrence a layperson could recognize as not normally happening absent negligence, whereas here the patient’s death after treatment for a serious illness did not similarly bespeak negligence.
• Garcia-Rueda v. Pascasio, 278 SCRA 769 (1997) — Cited for the definition of medical malpractice and the four essential elements a plaintiff must prove: duty, breach, injury, and proximate causation.

• Article 1733, Civil Code — Imposes upon common carriers the duty to observe extraordinary diligence in the vigilance over goods and for the safety of passengers. The Court distinguished this provision, holding that no equivalent statutory requirement applies to physicians, who are instead governed by the reasonable average diligence standard derived from general tort principles and professional regulation.
