Casumpang, et al. vs. Cortejo

In medical malpractice cases, an attending physician who fails to conduct comprehensive examinations and promptly order confirmatory tests despite evident symptoms of a serious illness breaches the standard of care; meanwhile, a hospital may be held solidarily liable for the negligence of an independent contractor-physician under the doctrine of apparent authority when the hospital's manifestations lead a reasonable patient to believe the physician is an employee or agent of the hospital, and the patient relies on such representation.

On April 22, 1988, Mrs. Jesusa Cortejo brought her 11-year-old son Edmer to the Emergency Room of San Juan de Dios Hospital (SJDH) due to difficulty in breathing, chest pain, stomach pain, and fever. Mrs. Cortejo used her Fortune Care health card and was referred to Dr. Noel Casumpang, a pediatrician accredited with the health maintenance organization. Dr. Casumpang initially diagnosed Edmer with bronchopneumonia based on a chest x-ray and brief examination, dismissing the mother's concerns about blood in her son's sputum and other symptoms inconsistent with that diagnosis. Despite progressive symptoms including vomiting of blood, severe stomach pain, and thrombocytopenia, Dr. Casumpang failed to consider dengue fever until it was too late. Edmer died on April 24, 1988, from Dengue Hemorrhagic Fever Stage IV. His father, Nelson Cortejo, filed a damages suit against Dr. Casumpang, Dr. Ruby Sanga-Miranda (a resident physician who later examined Edmer), and SJDH.

• On April 22, 1988, at approximately 11:30 a.m., Edmer Cortejo was brought to SJDH exhibiting difficulty in breathing, chest pain, stomach pain, and fever.
• Dr. Ramoncito Livelo initially examined Edmer, took vital signs, and diagnosed him with bronchopneumonia based on a chest x-ray.
• At 5:30 p.m. of the same day, Dr. Noel Casumpang, the assigned attending physician, examined Edmer using only a stethoscope and confirmed the diagnosis of bronchopneumonia.
• Mrs. Cortejo expressed doubts about the diagnosis, noting Edmer had high fever but no colds or cough; Dr. Casumpang dismissed her concerns by stating "that's the usual bronchopneumonia, no colds, no phlegm" and stayed only one to two minutes.
• At 9:00 a.m. on April 23, 1988, during his second visit, Dr. Casumpang again examined Edmer for approximately two minutes. Mrs. Cortejo reported traces of blood in Edmer's sputum, throat irritation, chest pain, stomach pain, and rapid breathing. Dr. Casumpang merely nodded, asked if Edmer had asthma, and reiterated the bronchopneumonia diagnosis without examining the throat or ordering confirmatory tests.
• At around 11:30 a.m. on April 23, Edmer vomited phlegm with blood streaks. Dr. Ruby Sanga-Miranda, a second-year resident physician, arrived 45 minutes later. She examined Edmer and initially confirmed the bronchopneumonia diagnosis, though she noted low-grade fever and rashes not typical of dengue.
• At 3:00 p.m., Edmer vomited blood again. Dr. Miranda examined the sputum, suspected dengue, conducted a tourniquet test (which was negative), inserted a nasogastric tube, and ordered blood tests.
• At 4:40 p.m., Dr. Miranda called Dr. Casumpang to report Edmer's condition. Blood test results at approximately 6:00 p.m. confirmed Dengue Hemorrhagic Fever.
• Dr. Casumpang arrived at the hospital at approximately 7:00 p.m. and ordered hematocrit, hemoglobin, blood typing, and tourniquet tests, but these came too late. He ordered platelet concentrate transfusion instead of blood transfusion.
• At midnight, Edmer was transferred to Makati Medical Center, where he was diagnosed with Dengue Fever Stage IV in its irreversible stage. He died at 4:00 a.m. on April 24, 1988, due to hypovolemic shock/hemorrhagic shock secondary to Dengue Hemorrhagic Fever Stage IV.
• The respondent, Nelson Cortejo (Edmer's father), testified that he and his wife did not know any doctors at SJDH and relied on the hospital's referral through their Fortune Care card. They were not informed that Dr. Casumpang was an independent contractor.
• Expert witness Dr. Rodolfo Jaudian, a pathologist with extensive experience in dengue cases, testified that Edmer's symptoms (rapid breathing, chest and stomach pain, fever, blood in saliva) were classic signs of dengue fever, and that the standard of care required immediate oxygen inhalation, analgesics, fluid infusion, and blood transfusion once bleeding occurred.

• Dr. Casumpang contended that he provided medical treatment to the best of his abilities within the proper standard of care, arguing that his initial diagnosis of bronchopneumonia was supported by the chest x-ray result and that dengue fever typically manifests only after several days of confinement.
• Dr. Casumpang raised doubts about Dr. Jaudian's credibility, claiming he lacked necessary training, skills, and experience as a specialist in dengue fever cases.
• Dr. Miranda argued that the function of making the diagnosis and undertaking medical treatment devolved upon Dr. Casumpang as the attending physician, and that she merely confirmed his diagnosis. She claimed her intervention actually led to the correct diagnosis of Dengue Hemorrhagic Fever.
• Dr. Miranda asserted there was no causal relation between the erroneous diagnosis for bronchopneumonia and Edmer's death, and questioned Dr. Jaudian's qualifications as he lacked formal residency training in pediatrics.
• SJDH maintained that Dr. Casumpang and Dr. Miranda were independent contractors and consultants, not employees, arguing that the hospital did not exercise control over their medical practice, did not pay them wages, and did not hire or fire them.
• SJDH claimed that accreditation of consultants does not constitute the "control" required under Article 2180 of the Civil Code, and that the hospital exercised due diligence in selecting and supervising the physicians.
• SJDH argued that the petitioning doctors arrived at an intelligently deduced diagnosis based on Edmer's initial symptoms, and that there was no reasonable indication of dengue fever at the time of admission.

• The respondent submitted that the issues raised were mainly factual, which are not reviewable under Rule 45, but argued that the petitioning doctors were negligent in failing to timely diagnose Edmer's correct illness due to non-observance of proper medical examination standards.
• The respondent contended that the medical examinations were not comprehensive, the doctors were always in a rush, and they employed a "guessing game" in diagnosing bronchopneumonia.
• The respondent alleged a causal connection between the doctors' negligence and Edmer's untimely death, asserting that with correct and timely diagnosis and proper management, dengue fever is not life-threatening.
• The respondent argued that SJDH was also negligent for lacking proper paging systems, bronchoscope equipment, adequate number of doctors, and an available ambulance driver when Edmer needed transfer.

• Procedural Issues:
  • Whether the Supreme Court, in a petition for review on certiorari under Rule 45 limited to questions of law, may resolve mixed questions of fact and law to determine the legal issues raised in a medical malpractice case.
• Substantive Issues:
  • Whether Dr. Casumpang committed medical negligence in diagnosing and treating Edmer Cortejo.
  • Whether Dr. Miranda committed medical negligence in her examination and treatment of Edmer Cortejo.
  • Whether there is a causal connection between the petitioners' negligent acts/omissions and the patient's resulting death.
  • Whether Dr. Rodolfo Jaudian was qualified to testify as an expert witness on the standard of care for dengue fever cases.
  • Whether SJDH is solidarily liable for the negligence of the petitioning doctors, and if so, under what legal basis (Article 2180 of the Civil Code or doctrine of apparent authority).

• Procedural:
  • The Court held that while its jurisdiction under Rule 45 is limited to questions of law, it may resolve factual questions when necessary to determine the legal issues raised, particularly in medical malpractice cases where the determination of negligence involves mixed questions of fact and law.
• Substantive:
  • The Court found Dr. Casumpang liable for medical negligence. He breached the standard of care by selectively appreciating only some symptoms while ignoring others (blood in sputum, throat irritation, rapid breathing), failing to conduct comprehensive examinations, and delaying confirmatory tests until it was too late. His failure to timely diagnose dengue fever and promptly administer proper treatment (blood transfusion, monitoring every 30 minutes, hemostatic) constituted negligence that was the proximate cause of Edmer's death.
  • The Court absolved Dr. Miranda of liability. As a resident physician functioning under the supervision of an attending physician, and given that two doctors had previously diagnosed bronchopneumonia, her failure to immediately discern the import of Edmer's second bleeding episode was an honest mistake of judgment influenced by her status in the hospital hierarchy and the prior diagnosis. She was not independently negligent as she promptly notified Dr. Casumpang when she suspected dengue and ordered necessary tests.
  • The Court found Dr. Jaudian qualified as an expert witness despite being a pathologist rather than a pediatrician, ruling that familiarity with the standard of care, acquired through study and practical experience (16 years of practice, attendance at pediatric seminars, handling of 50+ dengue cases), determines qualification, not merely the artificial classification by title or specialty.
  • The Court ruled that no employer-employee relationship existed between SJDH and the petitioning doctors under Article 2180 of the Civil Code because the hospital did not exercise control over the means and methods of their medical practice.
  • However, the Court held SJDH solidarily liable with Dr. Casumpang under the doctrine of apparent authority or agency by estoppel. By holding itself out as a provider of complete medical care and referring Dr. Casumpang to the patient without disclosing his independent contractor status, SJDH clothed him with apparent authority. The patient relied on the hospital to provide care rather than upon a specific physician, satisfying the requirements for apparent authority.

• Medical Malpractice (Elements) — Defined as a specialized area of tort law requiring proof of four elements: (1) duty arising from a physician-patient relationship; (2) breach of the standard of care; (3) injury; and (4) proximate causation. The Court applied this framework to determine liability, emphasizing that the physician-patient relationship may be implied from the physician's affirmative action to diagnose and treat.
• Standard of Care for Physicians — Physicians must use at least the same standard of care that a reasonably competent doctor would use under similar circumstances. A wrong diagnosis is not by itself malpractice unless it results from negligent conduct such as neglect of medical history or failure to order appropriate tests.
• Standard of Care for Resident Physicians — Resident physicians are subject to the same standard of care as attending physicians but their liability depends on factors including their authority to make independent diagnoses, the degree of supervision by the attending physician, and shared responsibility. Residents are not immune from liability for their own negligent acts but are not liable for honest mistakes of judgment influenced by hospital hierarchy.
• Expert Witness Qualification — The qualification of an expert witness depends on special knowledge, experience, and practical training that qualify him to explain technical matters to the court, not merely on matching specialties. A physician may testify as an expert on standards applicable to another specialty if he demonstrates sufficient familiarity through education, experience, or observation.
• Doctrine of Apparent Authority (Agency by Estoppel) — A hospital may be held vicariously liable for the negligence of an independent contractor-physician if: (1) the hospital acts in a manner that would lead a reasonable person to conclude the physician is an employee or agent; and (2) the patient acts in reliance upon the hospital's conduct consistent with ordinary care and prudence. The hospital need not make express representations; implied representations through the provision of emergency care and failure to disclose independent contractor status suffice.
• Employer-Employee Relationship (Control Test) — Under Article 2180 of the Civil Code, liability requires proof of selection, engagement, payment of wages, power to hire and fire, and most crucially, the power to control not only the end result but the means and methods used to achieve it. Mere accreditation and screening of consultants do not constitute the control required for employer-employee liability.

• "When a patient exhibits symptoms typical of a particular disease, these symptoms should, at the very least, alert the physician of the possibility that the patient may be afflicted with the suspected disease."
• "We do not decide the correctness of a doctor's diagnosis, or the accuracy of the medical findings and treatment. Our duty in medical malpractice cases is to decide—based on the evidence adduced and expert opinion presented—whether a breach of duty took place."
• "A wrong diagnosis is not by itself medical malpractice. Physicians are generally not liable for damages resulting from a bona fide error of judgment. Nonetheless, when the physician's erroneous diagnosis was the result of negligent conduct (e.g., neglect of medical history, failure to order the appropriate tests, failure to recognize symptoms), it becomes an evidence of medical malpractice."
• "Medicine is not an exact science; and doctors, or even specialists, are not expected to give a 100% accurate diagnosis in treating patients who come to their clinic for consultations."
• "It is the specialist's knowledge of the requisite subject matter, rather than his/her specialty that determines his/her qualification to testify."
• "By referring Dr. Casumpang to care and treat for Edmer, SJDH impliedly held out Dr. Casumpang, not only as an accredited member of Fortune Care, but also as a member of its medical staff."

• Jarcia, Jr. v. People of the Philippines — Cited for the principle that a physician-patient relationship is established when doctors examine a patient and assure the mother that everything is fine, thereby creating legal duty. Also cited for the standard that failure to perform extensive medical examination constitutes negligence.
• Spouses Flores v. Spouses Pineda — Cited for the ruling that failure to immediately order tests to confirm a patient's illness, despite suspicion of a particular disease, constitutes negligence when symptoms should alert the physician of the possibility.
• Nogales v. Capitol Medical Center — Cited as the leading Philippine case applying the doctrine of apparent authority, establishing the two-factor test: hospital's manifestations and patient's reliance.
• Gilbert v. Sycamore Municipal Hospital — US case cited for the proposition that under the doctrine of apparent authority, a hospital can be held vicariously liable for the negligent acts of a physician providing care at the hospital, regardless of independent contractor status, unless the patient knows or should have known of the independent contractor relationship.
• Pamperin v. Trinity Memorial Hospital — US case cited for the rule that hospitals create apparent authority by providing emergency room care and failing to advise patients that they are being treated by independent contractors.
• Ramos v. Court of Appeals — Cited for the test in determining existence of employer-employee relationship under Article 2180.
• Cereno v. Court of Appeals — Cited for the principle that an expert witness's specialty must match the area of practice involved or demonstrate sufficient familiarity with the standard of care.
• Jenkins v. Clark and Centman v. Cobb — US cases cited for the rule that residents and interns must exercise the same standard of care applicable to physicians with unlimited licenses, and that the standard is not individualized but that of physicians in general in the community.
• Brown v. Sims, Frost v. Mayo Clinic, Evans v. Ohanesian, and Brown v. Mladineo — US cases cited for the liberal approach in qualifying expert witnesses, holding that familiarity with the standard of care, rather than the witness's specialty title, determines admissibility.

• Article 2176 of the Civil Code — The foundation for quasi-delicts and medical malpractice actions, imposing liability for damages caused by fault or negligence.
• Article 2180 of the Civil Code — The provision on employers' vicarious liability for damages caused by their employees. The Court held this inapplicable because no employer-employee relationship existed between SJDH and the doctors, as the hospital did not exercise control over the means and methods of medical practice.
• Rule 45 of the Rules of Court — Governs petitions for review on certiorari, limiting review to questions of law, though the Court noted exceptions for mixed questions of fact and law in medical malpractice cases.

• N/A (Associate Justices Carpio, Villarama, Jr., Mendoza, and Leonen concurred in the decision without filing separate concurring opinions.)
