Antidepressant discontinuation patterns and characteristics across sociodemographic groups in the United States
Journal of Affective Disorders(2024)
摘要
Background
While antidepressants are frequently used, less is known about contemporary discontinuation patterns, especially across different sociodemographic populations.
Methods
Patients 16–84 years initiating antidepressants between 2016 and 2019 within a large US health insurer were identified. The association between patient characteristics and time until antidepressant discontinuation was evaluated using adjusted Cox proportional hazard regression.
Results
Across 1,365,576 patients, mean time to discontinuation was 168.1 days (SD:223.6). Men were more likely to discontinue than women (HR:0.94, 95%CI:0.94–0.94). Younger patients (16–24 years) were more likely to discontinue than older patients. Patients who were non-White (Asian HR:1.33, 95%CI:1.31–1.34; Black HR:1.27, 95%CI:1.27–1.28; Hispanic HR:1.34, 95 %:CI 1.34–1.35), with substance use disorder (HR:1.31, 95%CI:1.27–1.35), or taking tricyclic antidepressants (HR:1.26, 95%CI:1.25–1.27) were more likely to discontinue.
Limitations
Information on reasons for discontinuation was not included in the study, and wide standard deviations for the primary outcome were reported. The results may not be generalized to non-commercially insured beneficiaries.
Conclusions
Discontinuation is common within the first 6 months of treatment but varies across populations, highlighting patients who may benefit from potential intervention.
