Evaluation and optimization of take-home naloxone in an academic medical center.

With the United States in the midst of an opioid overdose epidemic, efforts to reduce overdose deaths have increased. Expanding access to the opioid antagonist naloxone can combat the epidemic. A pilot project in a psychiatric hospital resulted in the development of a screening tool in the electronic medical record (EMR) to help pharmacists identify adult inpatients at high risk of opioid overdose. Pharmacists can facilitate these patients being discharged with take-home naloxone. The purpose of this project was to optimize the screening tool for nonpsychiatric adult inpatient areas. Prior to implementation, a team of pharmacists familiar with the screening tool and take-home naloxone met with stakeholders to assess need for modification of the tool, determine barriers to implementation, and provide insight into the new service. In addition to expanding the tool into nonpsychiatric areas, a morphine-equivalents calculator was developed to identify patients receiving at least 100 mg of morphine equivalents per day to capture an additional at-risk population. Four short educational videos were developed to provide training to pharmacists. Initial performance of the screening tool was evaluated in general medicine patients over a 5-day period. Out of 44 admissions, 8 (18.2%) screened positive. The majority of those patients (5/8, 62.5%) screened positive for morphine equivalents greater than 100 mg. Anecdotally, the educational videos have been well received by pharmacy staff. Opioid overdose risk factors can be applied to nonpsychiatric inpatients for screening purposes in the EMR. Educational videos can be used to disseminate information to pharmacists on take-home naloxone and opioid overdose.
