Neurosurgical Malpractice Litigation: A Systematic Review and Meta-Analysis.

ABSTRACT

BACKGROUND: Neurosurgery has 1 of the highest risks for medical malpractice claims. We reviewed the factors associated with neurosurgical malpractice claims and litigation in the United States and reported the outcomes through a systematic review of the literature. METHODS: We conducted a systematic review of the literature according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines using the Medline, Embase, Cochrane, PubMed, and Google Scholar databases. We sought to identify pertinent studies containing information about medical malpractice claims and outcomes involving neurosurgeons in the United States. RESULTS: We identified 15 retrospective studies spanning from 2002 to 2023 that reviewed over 7890 malpractice claims involving practicing neurosurgeons in the United States. Disparities were evident in neurosurgical litigation, with 474 cases linked to brain-related surgeries and a larger proportion, 1926 cases, tied to spine surgeries. The most commonly filed claims were intraprocedural errors (37.4%), delayed diagnoses (32.1%), and failure to treat (28.8%). Less frequently filed claims included misdiagnosis or choice of incorrect procedure (18.4%), occurrence of death (17.3%), test misinterpretation (14.4%), failure to appropriately refer patients for evaluation/treatment (14.3%), unnecessary surgical procedures (13.3%), and lack of informed consent (8.3%). The defendant was favored in 44.3% of claims, while in 31.3% of lawsuits were dropped, 17.7% of verdicts favored the plaintiff, and 16.6% reached an out of court settlement. Only 3.5% of lawsuits found both parties liable. CONCLUSION: Neurosurgery is a high-risk specialty with 1 of the highest rates of malpractice claims. Spine claims had a significantly higher rate of filed malpractice claims, while cranial malpractice claims were associated with higher litigation compensation. Predictably, spinal cord injuries play a crucial role in predicting litigation. Importantly, nonsurgical treatments are also a common source of liability in neurosurgical practice.
