Factors Influencing Early Readmission after Discharge against Medical Advice from the Emergency Department

Discharge against medical advice (DAMA) and readmissions are important issues worldwide and can lead to adverse clinical outcomes, financial burden, and exposure of healthcare workers to unintended medical disputes. This study aimed to identify factors that affect readmissions within 48 h after DAMA. This retrospective study utilized the medical records of patients who visited an emergency medical center in Korea for treatment and were readmitted during a 10-year period. Factors predicting readmission after being DAMA were identified using logistic regression analysis. The total number of patients who were DAMA during the study period was 5445, of which 351 were readmitted to the emergency department within 48 h (6.4%). Factors influencing readmission included medical aid (odds ratio (OR) = 2.02, 95% confidence interval (CI): 1.46-2.83) and foreign worker insurance (OR = 2.07, 95% CI: 1.04-4.09) as their health insurance, as well as presenting for readmission by car (OR = 1.41, 95% CI: 1.08-1.82). Healthcare workers should treat patients who are DAMA and those who are likely to return with a more careful and preventative management strategy so that potential clinical, legal, and economic impacts of DAMA can be mitigated.
