Abstract
Objective: To compare patient and burn characteristics between patients who had a pre-existing psychiatric diagnosis and patients who did not in a Bum Unit at an academic hospital.
Background: Psychosocial issues are common in patients recovering from a burn; however, little is known regarding hospital course and discharge outcomes in patients with a preexisting psychiatric diagnosis presenting with a burn. Baseline medical comorbidities of burn patients have been shown to be a significant risk for in-hospital mortality.
Methods: A retrospective chart review of 479 consecutive patients admitted to the Bum Unit of an academic hospital in Halifax, Nova Scotia between March 2nd 1995 and June 1st 2013 was performed. Extensive data regarding patient and bum characteristics and outcomes was collected. Patients with and without pre-existing psychiatric diagnoses at the time of hospital admission were compared.
Results: Sixty-three (13%) patients had a psychiatric diagnosis, with the most common being depression (52%). Forty-percent (n=25/63) of these patients had multiple pre-existing psychiatric diagnoses. Patients with a psychiatric diagnosis had a greater total-body-surface area (TBSA)% covered by a third-degree bum (p=0.001), and were more likely to have an inhalation injury (p <0.001). These patients were also significantly more likely to experience 6 of the 10 most prevalent in-hospital complications and had a higher mortality rate (p=0.02). They were less likely to be discharged home (p=0.001), and more likely to go to a home hospital (p =0.04) or rehabilitation facility (p = 0.03). Psychiatric diagnosis was associated with significantly more placement issues (e.g. rehab bed unavailability, homeless) upon discharge from the Burn Unit (p=0.01). The risk of death in burn patients with pre-existing psychiatric disorders was about three times the risk of death in patients with no psychiatric disorders when adjusting for other potential confounders (95% CI, 1.13-9.10; p-value 0.03).
Conclusion: Presence of a pre-existing psychiatric disorder in the burn patient was associated with worse outcomes and was a significant predictor of death. Psychiatric diagnoses should be identified early in burn treatment and efforts should be made to ensure a comprehensive approach to inpatient support and patient discharge to reduce unfavorable bum outcomes and placement issues.
