A review of medical malpractice cases in congenital cardiac surgery in the Westlaw database in the United States from 1994 to 2019

Background Medical malpractice litigations are common for cardiac surgeons, and congenital cardiac surgeons are uniquely held accountable by patients, who are minors, and their families. Therefore, it is imperative for physicians to be cognizant of clinically effective and legally tenable practices. Methods The Westlaw legal research service was utilized to collect medical malpractice litigations from 1994 to 2019 pertaining to congenital cardiac surgery, inclusive, in the United States. Court documents were manually screened, with 177 litigations satisfying criteria for inclusion. Data collection included patient demographics, verdict and litigation characteristics, and clinical data. Fisher's exact test was used to assess the significance of association. Results Across the 177 litigations, 44% had defendant verdicts, 30% had plaintiff verdicts, and 26% had settlements. The average plaintiff award was $9,363,710, and the average settlement was $4,141,825. Patient mortality occurred in 87 cases (49.2%), and wrongful death claims were argued in 71 cases (40%). The most common reason for litigation were procedural errors (79 cases, 45%). The most frequent clinical event was cardiac arrest (95 cases, 54%). California recorded the most litigations (34 cases, 19.2%). Defendant verdicts were significantly associated with cardiac arrest, procedural errors, and permanent neurological injury (p < .05). Conclusions Defendant's verdicts were more common in cases with patient mortality, which had lower average plaintiff awards and settlements, since future healthcare expenses are inapplicable to this cohort. Future litigations can be minimized with an emphasis on reducing procedural errors, treating and diagnosing patients timely, and monitoring patients sufficiently.
