Primary objective: To investigate if patients with traumatic brain injury, who are discharged to the community before emergence from post-traumatic amnesia (PTA), experience more adverse outcomes than those discharged after emergence from PTA.Research design: A retrospective review of previously collected data and medical records.Methods and procedures: Occurrences of adverse events including hospital readmissions, disengagement from follow-up services, non-compliance with discharge precautions, support system breakdown or undue carer strain at the post-discharge clinic review were recorded. The Glasgow Outcome Scale – Extended (GOS-E) and Supervision Rating Scale (SRS) were completed, retrospectively. Twenty-seven patients discharged to the community, prior to emergence from PTA, were compared to 20 patients discharged within seven days of emergence from PTA.Main outcomes and results: Patients discharged prior to emergence from PTA did not experience an increase in adverse outcomes and showed a higher level of engagement in follow-up services (p= 0.015). There was no difference between groups in the improvements from discharge to clinic review on the GOS-E (p= 0.113) and SRS (p= 0.165).Conclusions: Patients can be discharged prior to emergence from PTA, if all other discharge criteria have been met, without an increase in adverse outcomes.
