Is work organisation associated with work status 3 months after injury? Results from a case-control study of New Zealand workers.

BACKGROUND: Little empirical examination of the relationship between work organisational factors and return to work following injury has been undertaken despite the growing recognition of examining broader multi-dimensional contexts for recovery following injury. OBJECTIVE: To explore relationships between pre-injury work organisational factors and work status (working/work absent) 3-month after injury among people employed prior to injury. METHODS: Cases (work absent) and controls (working), selected from a larger study of injury outcomes according to reported work status 3-month after injury, completed a postal questionnaire. Work organisational factors were compared between cases and controls using univariate and multivariable analyses. RESULTS: One hundred and twelve participants completed the questionnaire (44 cases; 68 controls). Of 11 work organisation factors examined, organisational size was the only explanatory variable significantly associated with work status in the multivariable model. Higher odds of work absence were found in small (< 50 employees) (OR 5.6) and large (> 500 employees) (OR 7.2) workplaces, compared with medium-sized (50-500 employees) organisations. CONCLUSIONS: Variations in post-injury work patterns among those working pre-injury may be partly explained by organisation size. Future research examining work status following injury should examine the influence of work organisational factors in larger studies. [ABSTRACT FROM AUTHOR]
