IntroductionThis study evaluates the effectiveness of a hospital-based return to work (RTW) programme in facilitating injured workers to RTW earlier through personalised case management. Factors associated with programme effectiveness are also examined.MethodThis was a quasi-experimental study comparing 81 participants who underwent conventional treatment before the RTW programme with 108 participants who directly received the RTW intervention. Analyses included time to RTW and the factors associated with dropout. Stratified analysis and multivariate logistic regression were used to mitigate potential selection bias from the additional recruitment process for the intervention group.ResultsParticipants in the intervention group returned to work 59.5 days earlier, with 84% able to RTW 6 months post injury compared with the control (63%; P<0.01). Stratified analysis found the intervention to be associated with better RTW outcomes among males, younger workers, non-residents, blue-collared workers, workers from the construction, marine, manufacturing and metalworking industries, and workers having lower Work Ability score (WAS), while light-duty provision was a possible confounder. The better outcomes in the intervention group were also independent of company size and injury severity. After adjusting for the above factors, the intervention group had 2.2 times higher odds of RTW at 6 months (95% confidence interval 0.84–5.90). Lower WAS and longer delay in initial RTW assessment were associated with delayed RTW within the intervention group. Migrant workers experienced higher dropout rates, thus being identified as a vulnerable group.ConclusionThe RTW coordination model of care is effective in facilitating RTW, with early programme referral being an important facilitator and WAS as a useful screening tool for delayed RTW.
