- Abstract
Objectives In case of long-term sick leave, gradually increasing workload appears to be an effective component of work-directed interventions to reduce sick leave due to common mental disorders (CMD). CMD are defined as stress-related, adjustment, anxiety, or depressive disorders. We developed an exposure-based return-to-work (RTW-E) intervention and evaluated the effect on time-to-full return to work (RTW) among workers who were on sick leave due to CMD in comparison to those treated with care-as-usual (CAU). CAU is guideline-directed and consists of problem-solving strategies and graded activities. Methods Using a two-armed cluster-randomized trial, we randomized 56 occupational physicians (OP). Of these, 35 OP treated 160 workers at the start of their sick leave: 75 workers received RTW-E and 85 workers received CAU. These workers were followed over a 12-month follow-up period. The primary outcome measure was time-to-full RTW lasting ≥28 days without recurrence. To evaluate differences between groups, we used intention-to-treat and multilevel Cox's regression analysis. Results The median time-to-full RTW differed significantly between groups [hazard ratio (HR) 0.55; 95% con-fidence interval (95% CI) 0.33-0.89], The workers receiving RTW-E (209 days; 95% CI 62-256) had a prolonged time-to-full RTW compared to workers receiving CAU (153 days; 95% CI 128-178). Conclusions Workers on sick leave due to CMD treated with RTW-E showed a prolonged time-to-full RTW compared to those treated with CAU. We recommend that OP do not apply RTW-E but continue counseling workers on sick leave due to CMD according to CAU.
