Abstract: Objective To explore the case management model of return to work injured workers. Methods A retrospective cohort wasformed with 523 injured workers in rehabilitation centre. The social demographic information, medical data and intervention process wereextracted from the medical records. A Cox Regression Model was used to examine the effect of case management on work processes and otherrelevant factors affecting RTW. Results 275 cases (82.1%) out of the 335 subjects successfully returned to work after median absence durationof 36.0 days. Computer training prompted RTW outcomes (P<0.01), while disability adjustment activity showed an opposite effect(P<0.05). It showed that education level, family attitude to RTW and level of injury were significantly associated with outcomes of RTW.Conclusion Specific skills reconstruction and training would is one of the most important components of the case management interventionprogram on RTW. Although disability adjustment did not specifically benefit RTW, it might help in improving workers' general health status,and it should not be ignored in any case.
