Tardive dyskinesia (TD) is associated with prolonged exposure to dopamine receptor blockers including antipsychotics. This registry describes the prevalence and impact of involuntary movements (possible TD) in a real-world population of patients taking antipsychotics.
RE-KINECT (NCT03062033) aims to enroll 1,000 patients from 70 US psychiatric practices. Adults with ≥3 months lifetime exposure to antipsychotic(s) and ≥1 psychiatric disorder are eligible for two-tier screening: informal observation, and then clinician observation of abnormal involuntary movements in general body regions (head/face, neck/trunk, upper/lower limbs) and confirmation of possible TD. Based on clinician assessment, patients are assigned to Cohort 1 or Cohort 2 (without or with abnormal involuntary movements, respectively). In both cohorts, the following baseline assessments are included: clinician’s assessment of clinical psychiatric severity, patient perceived health‐related quality of life (EuroQOL 5-Dimensions), social burden/disability questionnaire (Sheehan Disability Scale), and 12-month retrospective chart review ofmedical and treatment history. Cohort 2 also participate in 12-month longitudinal evaluation. Interim baseline data are available from four sites.
Baseline data are currently available for 116 patients—mean age, 49.6 years; female, 60.3%; schizophrenia/schizoaffective disorder, 32.8%; at least 1 mood disorder, 84.5%, and 10.4 years mean cumulative lifetime exposure to antipsychotic(s). The most concerning health condition for both cohorts is their mental health (69.0%), followed by physical activity and nutrition (33.6%). 32.8% of subjects had clinician confirmation of possible TD.
This novel registry aims to evaluate the real-world potential impact/burden of TD. Preliminary analyses suggest that TD is common in patients with schizophrenia and mood disorders taking antipsychotics. Further analyses will explore the burden of illness in this population.
