Risk of hospital inpatient opioid overdose (RHINOO): a review of factors impacting naloxone administration in patients receiving opioids.

purposeOpioid medications remain a common treatment for acute pain in hospitalized patients. This study aims to identify factors contributing to opioid overdose in the inpatient population, addressing the gap in data on which patients are at higher risk for opioid-related adverse events in the hospital setting.

methodsA retrospective chart review of inpatients receiving at least one opioid medication was performed at a large academic medical center from January 1, 2022, through December 31, 2022. Patients who received naloxone were designated as the overdose group, while those who received opioids without naloxone served as the control group. Suspected risk factors were included in a multivariable direct logistic regression model to identify patients at higher risk for opioid-related adverse events.

resultsThe review included 11,050 admitted patients who received an inpatient opioid, of whom 130 received naloxone. Analysis revealed that patients with creatinine clearance (CrCl) < 60 mL/min, co-administered benzodiazepine, body mass index (BMI) > 30 kg/m

conclusionThese validated risk factors should be considered when administering opioid analgesics in the inpatient setting. Consideration should be given to reducing the dose and/or frequency of opioids in addition to the use of alternative analgesic modalities for patients with these risk factors to mitigate the risk of opioid-related adverse events. Incorporating these considerations into clinical practice can enhance patient safety and outcomes.
