Medical Malpractice and Trigeminal Neuralgia: An Analysis of 49 Cases

Abstract

Background

Our study aims to fill the vacancy of litigation studies related to trigeminal neuralgia management, and to give healthcare providers the necessary information needed to better understand the potential litigious outcomes that often follow certain treatment methods.

Methods

We queried the Westlaw Edge legal database to identify litigation cases related to the management of trigeminal neuralgia for the years 1985-2019 using the following search criteria: (trigeminal & neuralgia), (tic & douloureux) and (microvascular & decompression). Key variables extracted included the following: plaintiff medical complaints, trial outcome, payout, and demographic characteristics. Continuous variables were compared between cases in favor of defendant and cases in favor of plaintiff using t-test or Wilcoxon rank sum test. Categorical variables were compared using chi-square or Fischer’s exact test.

Results

49 cases met the inclusion criteria – for those cases surgical complication (42.9%) and failure to diagnose (32.7%) were cited as the most common alleged reasons for filing a malpractice claim. Cranial nerve deficits (34.7%) and loss of consortium (12.2%) were the most frequent post-operative complaints. Verdicts ruled in favor of the defendant in 61.2% of cases, and for the plaintiff in 26.5% of cases with a mean payout of $1,982,428.46. Dental specialists were included in the most cases, 63.3%, and the average payout was $415,908, while Neurosurgical specialists were involved in 20.4% of cases with an average payout of $618,775. Cases where the verdict was in favor of the plaintiff were more likely to be older than cases with a verdict in favor of the defendant (p=0.03).

Conclusions

Over one-half of the cases resulted in a defendant’s verdict with surgical complications cited as the most common reason for litigation. Dentistry and neurosurgery were listed as the most common individual physician specialties for defendants, also contributing to the largest average payouts based on specialty (for specialties > 1 occurrence). Cranial nerve deficits and loss of consortium were the most common plaintiff post-operative complaints. A key implication of this study is the need for more extensive discussions between physician and patient regarding informed consent, especially when neurosurgical interventions are required.
