PURPOSE: To examine the relationship between different intervention approaches and subsequent real-life outcomes in patients changing treatment from escitalopram 10 mg. METHOD: This was a retrospective cohort study of patients starting antidepressant treatment between 2002 and 2004. Data were extracted from a US health-insurance reimbursement claims database. Eligible patients started escitalopram 10 mg and changed within 3 months to: escitalopram >/=20 g; another antidepressant; or a combination of escitalopram with another antidepressant. Medication persistence and healthcare costs over 3 months were compared between the treatment groups. RESULTS: Overall, 37,791 patients started escitalopram 10 mg. Of the 12,830 patients (34%) who changed treatment, 56% increased escitalopram dose, 26% switched antidepressant and 18% combined escitalopram with another antidepressant. Patients in the switch and combination groups had significantly higher rates of non-persistence (56% and 91%, respectively) vs the dose-increase group (39%; both P<0.001). Combination-group patients incurred significantly greater costs vs the dose-increase group ($2805 vs $1767, respectively; P<0.001). CONCLUSION: Results suggest that increasing escitalopram dose in patients responding inadequately to 10 mg is associated with higher persistence rates vs the other treatment approaches. Receiving an increased dose of escitalopram was associated with significantly lower costs than combining escitalopram 10 mg with another antidepressant
