This study sought to understand the evolving continuing medical education (CME) needs of physicians managing patients with tardive dyskinesia (TD). A case-based survey was developed, and later updated, to assess current practice, knowledge, and attitudes of neurologists and psychiatrists in the management of patients with TD. The original and updated survey were fielded in May 2018 and March 2020, respectively, to US-practicing psychiatrists and neurologists. Results were obtained from 213 psychiatrists and 187 neurologists in 2018 and from 125 psychiatrists and 128 neurologists in 2020. Less than half of physicians in both 2018 and 2020 were able to correctly identify the prevalence of TD in patients on maintenance antipsychotics, with many underestimating reported prevalence. Respondents reported moderate familiarity with VMAT2 inhibitor therapies for TD, with self-reported familiarity increasing more among neurologists than psychiatrists since the 2018 study. Psychiatrists are more likely than neurologists to take responsibility for medical management of TD symptoms and antipsychotic medication adjustment. Despite recommendations from APA guidelines and AAN reviews, 15% of physicians would use an anticholinergic to manage TD symptoms and only about half would opt for a VMAT2 inhibitor. There was a larger increase in VMAT inhibitor use between 2018 and 2020 among neurologists as compared to psychiatrists. The findings support the need for CME on TD focused toward specific provider groups. While both types of specialists would benefit from CME on the topic of TD epidemiology, there is an increased need for CME that includes treatment updates among psychiatrists.
