Efficacy of a Work Disability Prevention Program for People with Rheumatic and Musculoskeletal Conditions: A...

Work disability rates are high among people with rheumatic and musculoskeletal conditions. Effective disability preventive programs are needed. We examined the efficacy of a modified vocational rehabilitation approach delivered by trained occupational therapists and physical therapists on work limitation and work loss over 2 years among people with rheumatic and musculoskeletal conditions.

Eligibility criteria for this single-blind, parallel-arm randomized trial included ages 21-65 years, 15 or more hours/week employment, a self-reported doctor-diagnosed rheumatic or musculoskeletal condition, and concern about staying employed. The intervention consisted of a 1.5-hour meeting, an action plan, written materials on employment supports, and telephone calls at 3 weeks and 3 months. Control group participants received the written materials. The primary outcome was the Work Limitations Questionnaire (WLQ) output job demand subscale. The secondary outcome was work loss. Intent-to-treat analyses were performed.

Between October 2011 and January 2014, 652 individuals were assessed for eligibility. A total of 287 participants were randomized: 143 intervention and 144 control participants. In total, 264 participants (92%) completed 2-year data collection. There was no difference in the mean ± SD WLQ change scores from baseline to 2-year followup (-8.6 ± 1.9 intervention versus -8.3 ± 2.2 control; P = 0.93). Of the 36 participants who experienced permanent work loss at 2 years, 11 (8%) were intervention participants and 25 (18%) control participants (P = 0.03).

The intervention did not have an effect on work limitations but reduced work loss. The intervention can be delivered by trained rehabilitation therapists.
