A closed claims analysis of vocal cord injuries related to endotracheal intubation between 2004 and 2015.

Abstract

To provide a contemporary medicolegal analysis of claims brought against anesthesiologists for injuries related to endotracheal intubation. A retrospective study of closed claims data from the Controlled Risk Insurance Company (CRICO) Comparative Benchmarking System (CBS) database between 2004 and 2015. Closed claims that occurred in any surgical specialty in which the patient was undergoing general anesthesia and anesthesiology was named as the primary responsible service. Twenty claims were identified for analysis in 7 surgical specialties. Patient ages ranged from 45 to 76. Data regarding patient comorbidities and case history were obtained when available. None. Data collected includes patient demographics such as age, outcome severity, alleged complication, plaintiff allegations, contributing factors to the injury, the surgical specialty in which the injury occurred, and the ultimate result of the claim (dismissed/denied/settled). Out of 20 claims, settlement payments were made in 10% of claims with a mean payment amount of $7669. Mean patient age was 55.6years. Within severity of injuries, 65% of claims were classified as "Permanent Minor." The most common contributing factor in claims was "Technical Knowledge/Performance" and the most common plaintiff allegation was "Trauma from endotracheal tube placement." Bilateral vocal cord paralysis, unilateral (left-sided) vocal cord paralysis, and laryngeal nerve injury were the top alleged complications. The surgical specialty in which claims most often resulted was orthopedic surgery. Injuries related to endotracheal intubation remain an ongoing challenge to anesthesiologists. Their etiology is often multifactorial and was found in this study to stem most commonly from technical errors and patient co-morbidities. A detailed discussion of risks with patients during the consent process, careful documentation of such discussion, and prompt referral to specialists when needed are critical. Understanding the patterns related to injuries during intubation is essential in order to develop strategies for improved patient safety and outcomes.
