Impact of Collaborative Care on Absenteeism for Depressed Employees Seen in Primary Care Practices: A Retrospective Cohort Study.

Objective: The impact of "real world" collaborative care on depression and absenteeism for depressed employees seen in primary care practices using objective employer absence data.
Methods: A retrospective cohort study comparing depressed employees seen in primary care practices who enrolled for a "real world" collaborative care program to practice as usual (PAU) on objective absence days and depression response and remission at 6, and 12-month time periods.
Results: Absence days were more in the collaborative care group compared with the PAU group at 3 and 6 months but at 12 months the difference was no longer statistically significant. Collaborative care led to better response and remission depression scores compared with PAU at 12 months.
Conclusions: Collaborative care led to faster improvement in depression symptoms but did not translate to less time away from work.
