Incidence, course and risk factors of head injury: a retrospective cohort study.

ABSTRACT: OBJECTIVES:To assess the incidence of head injury and predictors of complication across the care continuum. DESIGN:Retrospective cohort study using data from a research network. We calculated the incidence of overall head injury in a longitudinal cohort covering 1-year interval (31 369 patient-years), and the incidence of complicated head injury in a longitudinal cohort covering 10 years interval (220 352 patient-ears). Incidence rates were calculated per 1000 patient-years with 95% CI using the Mid-P exact test. We calculated ORs to assess potential risk factors for a complicated head injury. SETTING:A practice-based research network covering a population of >30 000 patients. PARTICIPANTS:All patients listed in practices within the research network during the years 2005-2014.
