Medical Negligence | Failure To Investigate Known 'Red-Flag' Findings In Diagnostic Reports Constitutes Breach Of Duty Of Care: NCDRC

"The family physician, specialist or super-specialist, when she fails to identify the elementary signs or indications in the diagnostic reports, which signs are medically well-known red-flags, as in the present case, she cannot be held to have exercised due patient care and skill expected of an ordinary medical professional" National Consumer Disputes Redressal Commission (NCDRC), in a significant ruling, has held that medical professionals are under a mandatory duty of care to holistically evaluate diagnostic reports and investigate "red-flag" findings, even if those findings appear unrelated to the primary complaint.

A bench led by President Justice A.P. Sahi and Member Bharatkumar Pandya observed that the failure to investigate clear indications of malignancy, such as lymphadenopathy, in a patient with a known cancer history constitutes a patent lack of requisite patient care.

The complainant alleged gross medical negligence leading to the death of his mother, a known cancer survivor. In March 2013, an MRI of her lumbar spine revealed a large lobulated "space-occupying lesion" (SOL) of 46x35x50 mm, suggestive of common iliac lymphadenopathy. Despite this, the orthopaedic surgeon (OP-2) and neurosurgeon (OP-3) at Apollo Hospitals, Bhubaneswar, proceeded with a laminectomy without conducting a biopsy or oncological referral. The malignancy was only diagnosed months later in an advanced stage, eventually leading to the patient's death.

The primary question before the Commission was whether the failure of the treating doctors to investigate or even acknowledge the "red-flag" findings of lymphadenopathy in the MRI report—given the patient’s history of multiple cancers—amounted to medical negligence. The court was also tasked with determining whether a doctor can escape liability by claiming that the reported finding did not fall within their specific field of expertise (orthopaedics/neurosurgery).

The NCDRC emphasized that the duty of care for a specialist at a multi-speciality hospital is not confined to the specific procedure they are performing. The bench noted that medical practitioners are expected to exercise ordinary and elementary knowledge to identify clear diagnostic warnings.

Duty To Evaluate Diagnostic Reports

The Commission held that a specialist cannot ignore critical findings in an MRI report simply because those findings do not relate to the specific surgery being performed. The failure to record or act upon the "red-flag" of lymphadenopathy in a patient with a prior history of cancer was termed a "patent lack of requisite patient care."

"The expected degree of such concern and patient-care in a specialist orthopaedic surgeon or neurosurgeon at a multi-speciality hospital can validly be much higher," the bench observed. The court further clarified that the defence that a doctor is not an oncologist does not absolve them from the duty to seek further consultations when faced with clear clinical red-flags.

No Liability For Unfortunate Outcomes

While the Commission found the doctors negligent for failing to investigate, it refused to link this negligence directly to the patient’s death. The bench clarified that the death was caused by the progression of the malignancy, and it was speculative to suggest that earlier diagnosis would have altered the outcome.

"Linking of death of the patient... to the negligence or deficient service of the OP-2 and OP-3... is absolutely baseless and lacks any rational or medical foundation," the Commission held. Consequently, the doctors were held liable for the failure of duty in diagnosis, rather than for the eventual demise of the patient.

Expert Evidence Standards

Addressing the admissibility of the complainant's expert witness, the NCDRC clarified that while experts should ideally hold qualifications in the same speciality, a senior medical professional with significant experience (such as an MD in Forensic Medicine) is not a "layman" and their testimony regarding the failure to exercise due diligence remains relevant.

The Commission partly allowed the complaint, awarding a symbolic lump-sum compensation of Rs. 5 lakhs. The orthopaedic surgeon was held primarily liable for Rs. 3 lakhs, and the neurosurgeon for Rs. 2 lakhs, with the hospital held vicariously liable for the entire amount. The order underscores that even when an unfortunate outcome cannot be attributed to a doctor's error, the breach of the duty of care in diagnostic protocols remains actionable in consumer law.
