Naloxone-Prescribing Practices in a Freestanding Rehabilitation Hospital.

Abstract

The study aims to determine whether Physical Medicine & Rehabilitation physicians offer naloxone per the Centers for Disease Control and Prevention Guidelines to patients at the highest risk of complications from opioid treatment and whether there is a difference between inpatient and outpatient naloxone prescribing. A retrospective chart review on 389 adults (outpatient n = 166; inpatient n = 223) from May 4 to May 31, 2022, at an academic rehabilitation hospital. Prescribed medications and comorbidities were evaluated to determine whether Centers for Disease Control and Prevention criteria for offering naloxone were met and whether naloxone was offered. One hundred twenty-nine opioid prescriptions were written for 102 outpatients; 61 qualified for naloxone (morphine milliequivalent range = 10-1080, mean = 158.08). On inpatient, 68 patients received 86 opioid prescriptions; 35 qualified for naloxone (morphine milliequivalent range = 3.75-246, mean = 62.36). Overall, there was a significantly lower rate of opioid prescriptions for inpatients (30.49%) than outpatients (61.45%) ( P < 0.0001), a nonsignificant lower rate of inpatient (51.47%) than outpatient (59.80%) "at-risk" prescriptions ( P = 0.351), and a weakly significant lower rate of naloxone prescribing for inpatient (2.86%) than outpatient visits (8.20%) ( P < 0.0519). At this rehabilitation hospital, there was a low rate of naloxone prescribing by inpatient and outpatient providers, with a higher rate occurring in the outpatient than inpatient setting. More research is needed to understand this prescribing trend to determine potential interventions.
