Discharge prescribing of enteral opioids in opioid naïve patients following non-surgical intensive care: A retrospective cohort study.

Abstract Purpose To estimate the incidence of new prescription of enteral opioids on hospital discharge in opioid naive, non-surgical, critically ill patients and evaluate the risk factors associated with such occurrence. Methods Using hospital-wide and ICU databases, we retrospectively identified all patients (≥ 18 years old) who were admitted to the 20-bed adult ICU of Memorial Sloan Kettering Cancer Center (MSKCC) between July 1, 2015 and April 20, 2020. Patients' electronic medical records (EMR) were retrieved and patient demographics, peri-ICU admission data were captured and analyzed. Results During the study period, a total of 3755 opioid naive patients were admitted to the ICU and 848 patients met the inclusion criteria. Among these, 346 (40.8%) patients were discharged with a new opioid prescription. Age at ICU admission, preadmission use of benzodiazepine, and antidepressants, a diagnosis of sepsis, and use of mechanical ventilation, antidepressants or, opioid infusion for greater than 4 h during the ICU stay, hospital length of stay (LOS), and days between ICU discharge and hospital discharge were independently associated with increased odds of a new opioid prescription. Conclusions A significant proportion of opioid naive non-surgical ICU survivors receive a new opioid prescription on hospital discharge.
