AbstractIntroductionTardive Dyskinesia (TD) refers to abnormal, involuntary, choreoathetoid movements of the tongue, lips, face, trunk, and extremities and is associated with long-term exposure to dopamine-blocking agents, such as antipsychotic medications. Once established, these movements usually persist. The movements are disfiguring and can bring unwanted attention to affected individuals. When severe, especially if the respiratory muscles are affected, the movements can be disabling, limit activity, and reduce quality of life. The prevalence is 7.2% in individuals on newer antipsychotics who have never been exposed to older neuroleptics. Until recently, there were no effective treatments for TD. In recent years, many new treatments have been investigated for the treatment of TD, including valbenazine, deutetrabenazine, and branched chain amino acids. Valbenazine first, followed by deutetrabenazine are FDA approved to treat TD. A virtual broadcast was developed to assess the ability of continuing medical education (CME) to improve awareness of the recognition and treatment of TD among psychiatrists.MethodsThe virtual broadcast (May 9, 2020) consisted of a two-hour, live-streamed discussion between two expert faculty. Impact of the educational activity was assessed by comparing psychiatrists’ responses to four identical questions presented before and directly after activity participation. A follow-up survey was sent to all participants six-weeks post-activity to measure performance in practice changes. A chi-square test was used to identify significant differences between pre- and post-assessment responses. Cohen’s d was used to calculate the effect size of the virtual broadcast.ResultsActivity participation resulted in a noticeable educational effect among psychiatrists (n=621; d=6.12, P<.001). The following areas showed significant (P<0.05) pre- vs post-educational improvements: recognition of movements in patients with TD, rate of TD in SGA exposed patients, treatment options for TD (on and off-label), and treatment of TD using VMAT inhibitors. Additionally, 54% of psychiatrists reported a change in practice performance as a result of the education received in the activity, including utilization of a standard scale to evaluate movement disorders and educate patients and family members about potential for TD, how to recognize symptoms, and when to treat.ConclusionsThe results indicated that a CME-certified two-hour virtual broadcast was effective at improving knowledge among psychiatrists for the recognition and treatment of TD. This knowledge also resulted in positive changes in practice performance post-activity. Future education should continue to address best practices in the diagnosis, treatment and management of patients with TD, as there remains an increased need for tailored CME among psychiatrists.FundingNeurocrine Biosciences, Inc.
