To observe the longitudinal effects of antidepressant medication in a cohort of patients with advanced cancer
Of the 628 patients with advanced cancer in the study, 25% were receiving antidepressants for a median of 9.5 weeks. Patients were followed for six months or until death. Consecutive patients in the daycare unit were eligible for inclusion. Patients completed study assessments at baseline and at eight, 16, and 24 weeks. A patient self-report was used to identify patients taking antidepressants.
Observational
Patients who stated that they took antidepressants had significantly higher depression scores on both measures. A subgroup analysis was completed for those with the highest PHQ-9 scores, assuming that effects might be seen in those with greater depression levels. However, there were no differences in results between those taking and not taking antidepressants.
The observational findings of this study suggest that antidepressant medication had little impact in reducing depression scores for patients attending Hospice daycare service.
This observational study did not show that antidepressants reduced depression among patients receiving Hospice care. However, there were several study design and measurement limitations. The role and effectiveness of antidepressants may vary among patients at different phases in the trajectory of cancer.
