Inadequate follow-up care for depression and its impact on antidepressant treatment duration among veterans with and without diabetes mellitus in the Veterans Health Administration.
OBJECTIVE
Our objective was to describe the adequacy of follow-up care for depression and its association with antidepressant treatment duration among veterans with and without diabetes mellitus (DM).


METHODS
This was a retrospective study (1997-2005) of 2178 veterans (33% with DM) in a Midwestern Veterans Health Administration facility who had a new episode of unipolar depression. Adequate follow-up care was defined by a health care visit within 7 and 14 days, and >/=3 visits following antidepressant treatment initiation. Adequate treatment duration was defined by a medication possession ratio of >/=80%. Multivariate logistic regression was used to calculate odds ratios (ORs) adjusted for demographic, clinical and health care utilization characteristics.


RESULTS
Only 27% received >/=3 follow-up visits within 12 weeks, and <23% received follow-up within 2 weeks of antidepressant initiation. Subjects with DM were 1.36-fold more likely [95% confidence interval (95% CI)=1.05-1.75] to have received >/=3 visits but were similarly likely to have received follow-up within 7 days (OR=1.02; 95% CI=0.74-1.41) or 14 days (OR=1.08; 95% CI=0.83-1.40) of antidepressant initiation. Adequate follow-up care was the most important predictor of adequate treatment duration (OR=2.10; 95% CI=1.54-2.88).


CONCLUSIONS
DM had little influence on the adequacy of follow-up care for depression, with few exceptions. Follow-up care for depression is underutilized and has a significant impact on antidepressant treatment duration. Strategies to more effectively manage depression treatment are required.
