Substance use disorder in physicians after completion of training in anesthesiology in the United States from 1977 to 2013

Background: Substance use disorder among physicians can expose both physicians and their patients to significant risk. Data regarding the epidemiology and outcomes of physician substance use disorder are scarce but could guide policy formulation and individual treatment decisions. This article describes the incidence and outcomes of substance use disorder that resulted in either a report to a certifying body or death in physicians after the completion of anesthesiology training. Methods: Physicians who completed training in U.S. anesthesiology residency programs from 1977 to 2013 and maintained at least one active medical license were included in this retrospective cohort study (n = 44,736). Substance use disorder cases were ascertained through records of the American Board of Anesthesiology and the National Death Index. Results: Six hundred and one physicians had evidence of substance use disorder after completion of training, with an overall incidence of 0.75 per 1,000 physician-years (95% CI, 0.71 to 0.80; 0.84 [0.78 to 0.90] in men, 0.43 [0.35 to 0.52] in women). The highest incidence rate occurred in 1992 (1.79 per 1,000 physician-years [95% CI, 1.12 to 2.59]). The cumulative percentage expected to develop substance use disorder within 30 yr estimated by Kaplan-Meier analysis equaled 1.6% (95% CI, 1.4 to 1.7%). The most common substances used by 353 individuals for whom information was available were opioids (193 [55%]), alcohol (141 [40%]), and anesthetics/hypnotics (69 [20%]). Based on a median of 11.1 (interquartile range, 4.4 to 19.8) yr of follow-up, the cumulative proportion of survivors estimated to experience at least one relapse within 30 yr was 38% (95% CI, 31 to 43%). Of the 601 physicians with substance use disorder, 114 (19%) were dead from a substance use disorder-related cause at last follow-up. Conclusions: A substantial proportion of anesthesiologists who develop substance use disorder after the completion of training die of this condition, and the risk of relapse is high in those who survive.
