Abstract
Aims: Antidepressant use increases around long-term care facility (LTCF) entry, and initiation during hospitalizations may contribute to this. This study characterized the care setting (i.e., community-based, hospital or LTCF) where antidepressants were initiated and determined associated resident characteristics.
Methods: A cross-sectional study including non-Indigenous individuals aged 65–105 years who entered LTCFs in two Australian states during 2015–2019, and were dispensed an antidepressant within 2 months, was conducted. Care settings (community-based, hospital or LTCF) were determined from linked LTCF records, and hospitalizations ≤30 days before LTCF entry. Pharmaceutical claims before and after LTCF entry were screened to determine antidepressant initiation. Multivariate multinomial logistic regression estimated adjusted odds ratios (aORs) and 95% confidence intervals (95% CIs) for resident characteristics associated with care settings of antidepressant initiation
Results: This study included 34 525 residents from 1046 LTCFs. Overall, 27 160 (78.7%) commenced antidepressants prior to entry, 2552 (7.4%) in hospital and 4813 (13.9%) in LTCFs. Mirtazapine constituted 44.8% (n = 1143) of antidepressants initiated in hospitals and 39.5% (n = 1902) in LTCFs. Residents who were aged ≥90 years were more likely to start an antidepressant in the LTCF compared to community-based settings (aOR = 1.97, 95% CI 1.74–2.23). Residents recently using a psychotropic were more likely to start an antidepressant in community-based settings before LTCF entry, compared to a hospital or LTCF.
Conclusions: Individuals receiving antidepressants during transition to LTCFs are often already taking antidepressants prior to entry. Future interventions to optimize antidepressant use in LTCFs should consider setting, recency and indication for antidepressant initiation, and ongoing monitoring for safety.
