Injury-related emergency department visits and unplanned readmissions are associated with worse long-term mental and physical health

Abstract

BackgroundThe risk factors for unplanned emergency department (ED) visits and readmission after injury and the impact of these unplanned visits on long-term outcomes are not well understood. We aim to: 1) describe the incidence of and risk factors for injury-related ED visits and unplanned readmissions following injury and, 2) explore the relationship between these unplanned visits and mental and physical health outcomes 6–12 months post-injury. MethodsTrauma patients with moderate-to-severe injury admitted to one of three Level-I trauma centers were asked to complete a phone survey to assess mental and physical health outcomes at 6–12 months. Patient reported data on injury-related ED visits and readmissions was collected. Multivariable regression analyses were performed controlling for sociodemographic and clinical variables to compare subgroups. ResultsOf 7,781 eligible patients, 4675 were contacted and 3,147 completed the survey and were included in the analysis. 194 (6.2%) reported an unplanned injury-related ED visit and 239 (7.6%) reported an injury-related readmission. Risk factors for injury-related ED visits included: younger age, Black race, a lower level of education, Medicaid insurance, baseline psychiatric or substance abuse disorder and penetrating mechanism. Risk factors for unplanned injury-related readmission included younger age, male sex, Medicaid insurance, substance abuse disorder, greater injury severity and penetrating mechanism of injury. Injury-related ED visits and readmissions were associated with significantly higher rates of PTSD, chronic pain and new injury-related functional limitations in addition to lower SF-12 mental and physical composite scores. ConclusionsInjury-related ED visits and unplanned readmissions are common after hospital discharge following treatment of moderate-severe injury and are associated with worse mental and physical health outcomes.
