Summary
This retrospective cohort study from a United States level 1 trauma centre examined 5,343 traumatic brain injury patients between 2012 and 2020, of whom 977 (18%) had pre-existing psychiatric disorders. Using propensity-score matching to control for confounding, the authors found that patients with pre-existing psychiatric illness experienced significantly longer hospitalisation and ICU stays, suggesting psychiatric comorbidity may complicate recovery trajectories following TBI.
UK applicability
The findings are potentially relevant to UK trauma services and mental health integration pathways, though direct application would require validation in UK healthcare settings with potentially different case-mix and psychiatric service availability. UK trauma centres and psychiatric liaison services may benefit from awareness of this comorbidity effect.
Key measures
Hospital length of stay (LOS), ICU LOS, ventilator days, clinical outcomes in TBI patients with and without pre-existing psychiatric illness
Outcomes reported
The study measured hospital length of stay, ICU length of stay, ventilator days, and clinical outcomes in traumatic brain injury patients stratified by pre-existing psychiatric disorder status.
