Objectives:
We performed a descriptive analysis of patient and treatment characteristics in premature discharges "against medical advice" (AMA) in a cohort of patients with opioid-related hospitalizations.
Methods:
We abstracted data from 1152 opioid related hospitalizations of 928 adult patients in a large academic health system. Using electronic health record data, hospitalizations were categorized as AMA or conventional discharge (CD). To determine differences between AMA and CD regarding treatment characteristics, Fisher exact test, t tests, ANOVA, and logistic regression were performed.
Results:
74 / 1152 (6%) of opioid-related hospitalizations were discharged AMA. Hospitalizations that resulted in AMA discharge had shorter median length of stay (AMA vs CD 3.5 vs 5.5 days, P < 0.001) and received fewer of any type of opioid agonist treatment (AMA vs CD 73% vs 84%, P = 0.03). Although the number of hospitalizations in which methadone was administered did not differ between the AMA and CD groups, hospitalizations that resulted in AMA had more dose reductions and lesser quantities of methadone overall before discharge. Buprenorphine use was low overall in AMA and CD (0% and 2.1%, respectively).
Conclusion:
In this sample of opioid related hospitalizations, admissions that resulted in AMA discharge had fewer opioid agonist administrations and lower methadone dosing. These findings support efforts to initiate opioid agonist therapy during hospital admissions, and further studies should determine whether this practice mitigates AMA discharges.
