ABSTRACT
This study investigated inpatient surgical outcomes for people experiencing homelessness (PEH) in Australia. Retrospective administrative health data of emergency surgical admissions from a single center over five years, 2015 to 2020, was included. Independent associations between factors and outcomes were analyzed with binary logistic and log-linear regression. Of 11 229 admissions, 2% were experiencing homelessness. People experiencing homelessness were on average younger (49 vs 56 years), more likely to be males than females (77% vs 61%), suffer mental illness (10% vs 2%), and substance use disorders (54% vs 10%). People experiencing homelessness were not more likely to suffer surgical complications. However, male sex, older age, mental illness, and substance use were risk factors for poor surgical outcomes. Homelessness predicted greater odds of discharge against medical advice (4.3 times) and longer length of stay (1.25 times). These results highlighted the need for health interventions simultaneously addressing physical, mental health, and substance use issues in the care of PEH.
