Post-trauma morbidity, measured as sick leave, is substantial and influenced by factors unrelated to injury: a retrospective matched observational cohort study

Background Mortality as an endpoint has been the focus of trauma research whereas few studies investigate long-term outcomes in terms of morbidity. An adequate analysis of post-injury morbidity includes several dimensions, for this reason sick leavehas been used as a proxy for morbidity in the current study. The aim of this retrospective matched observational cohort studywas to investigate sick leavebefore and after trauma and factors associated with prolonged sick leave.
