Characteristics and outcomes of patients who discharge against medical advice from Australian and New Zealand burns services

Burns patients with recorded discharges against medical advice (DAMA) face potential medical and financial consequences associated with future readmissions. This study aimed to investigate the characteristics and outcomes of patients with recorded DAMA from burns services in Australia and New Zealand. In an observational study using data from individuals aged ≥ 16 years captured by the Burns Registry of Australia and New Zealand with a burn-related admission between July 2009 and June 2022, 325 patients (1.4 %) had recorded DAMA. A greater proportion of patients with recorded DAMA were aged 30-44 years, of Australian Aboriginal and Torres Strait Islander origin, from outer regional Australia, had pre-existing mental health conditions, with substance use, and sustained their injury through suspected assault or abuse. Injuries in patients with recorded DAMA were more severe. Compared to patients without DAMA, a greater proportion of patients with DAMA were readmitted within 28 days of discharge (13.8 % versus 4.9 %), with failed discharge processes (45.5 %) and infection (18.2 %) being the most frequently recorded reasons. They required readmission to the intensive care unit (20 % versus 8.6 %) with longer lengths of stay. Outcome findings remained similar in a matched cohort analysis between those with and without recorded DAMA. These findings highlight the consequences of DAMA, necessitating primary measures to address modifiable, cultural, and social factors preemptively to prevent DAMA among disadvantaged individuals, and secondary measures to minimize the impact of DAMA (e.g., adequate pain and wound discharge management, follow-up care, community-based treatments, etc.).
