Population-based analysis of the impact of trauma on longer-term functional outcomes

Abstract

Background: Functional outcome measures are important as most patients survive trauma. The aim of this study was to describe the long-term impact of trauma within a healthcare region from a social perspective. Methods: People active in work or education and admitted to hospitals in Central Norway in the interval 1 June 2007 to 31 May 2010 after sustaining trauma were included in the study. Clinical data were linked to Norwegian national registers of cause of death, sickness and disability benefits, employment and education. Primary outcome measures were receipt of medical benefits and time to return to preinjury work level. Secondary outcome measures were mortality within 30 days or during follow-up. Results: Some 1191 patients were included in the study, of whom 193 (16·2 per cent) were severely injured (Injury Severity Score greater than 15). Five years after injury, the prevalence of medical benefits was 15·6 per cent among workers with minor injuries, 22·3 per cent in those with moderate injuries and 40·5 per cent among workers with severe injuries. The median time after injury until return to work was 1, 4 and 11 months for patients with minor, moderate and severe injuries respectively. Twelve patients died within 30 days and an additional 17 (1·4 per cent) during follow-up. Conclusion: Patients experiencing minor or major trauma received high levels of medical benefits; however, most recovered within the first year and resumed preinjury work activity. Patients with severe trauma were more likely to receive medical benefits and have a delayed return to work. Registration number: NCT02602405 (http://www.clinicaltrials.gov).
