BACKGROUND Collaborative care with a care manager in primary care improves care. OBJECTIVE To study whether care manager support leads to improved work ability, decreased job strain and reduced time of sick leave among primary care patients with depression. METHODS A clinical effectiveness study of care managers for depression patients seeking care in primary care was conducted in a RCT 2014 -2016. Patients in the intervention group were assigned a care manager. In the 12-month follow-up, patients with employment (n = 269; intervention n = 142, control n = 127) were studied concerning work ability, job strain and sick leave. RESULTS An association was shown between reduction of depressive symptoms and improved work ability for the entire group. At 12-month follow-up a statistically significant difference of reduction of depressive symptoms was seen between the groups (MADRS-S: intervention 10.8 vs control 13.1, p = 0.05) as well as increased quality of life (EQ-5D: intervention 0.77 vs control 0.70, p = 0.04). In the intervention group, a concordance was found between the patient's prediction of return to work and the actual return to work (91%for intervention and 68 %for control group, p = 0.047). CONCLUSIONS Compared to usual care, the care manager does not seem to further improve perception of work ability, job strain or perception of social support per se among the patients despite a long-term effect on depression symptoms. The lack of a long-term effect regarding these aspects may be due to the fact that care manager support was only provided during the first three months.
