摘要
Background: Vocational Rehabilitation (VR) is an essential element of interventions aimed at re-integrating people with work disability into work. In this context, vocational retraining is of special importance. However, the success of vocational retraining, represented by subsequent returning to work (RTW), is only to a limited extent attributable to intervention quality. Apart from methodical influences participant-related as well as context-related attributes are discussed as influencing factors. To know these RTW predictors is a necessary condition for a valid comparative evaluation of intervention quality.
Methods: A structured literature search was conducted. All studies meeting the following criteria were included: publication between 2006 and 2011; context: German rehabilitation system and vocational retraining; multivariate analysis of RTW predictors. The evidence for or against the influence of a predictor was rated as strong if more than 75% of the models, and moderate if more than 50% of the models reported or excluded a significant relationship between predictor and RTW. All predictors included in more than 2 studies were considered in this review.
Results: 15 publications from 6 studies were included in the analysis. Due to differentiation of the models between different types of retraining the evidence was based on 9 prediction models. Strong evidence of an effect on RTW can be assumed for income before admission, subjective health rating and regular completion of retraining. There is moderate evidence for an effect of age and target job. Strong evidence against an effect on RTW is found for employment and occupational status before admission. There is moderate evidence against an RTW effect of sex, education and locus of control. Ambiguous evidence is obtained for the local job market, the type of retraining, social support and mobility.
Conclusions: For the first time the review provides findings on the relevant influence factors of RTW following vocational retraining. These findings on the one hand could lead to an advance of intervention quality due to consideration of special personal and/or environmental factors. On the other hand there still remains an undeniable lack of information in this field. There is a special need for studies capable of confirming previous findings or of clarifying known uncertainties in the available evidence.
