摘要:
Background Medications for opioid use disorder (MOUD) including buprenorphine is recommended for patients with opioid use disorders. We sought to evaluate the frequencies of respiratory depression, intubation, and naloxone administration, and clinical outcomes among patients reported to the National Poison Database System (NPDS) following single-substance and multiple-substance buprenorphine oral exposures. Methods NPDS was queried for all MOUD-approved buprenorphine product exposures between 1 January 2003 and 31 December 2019. Data abstracted included year, route, gender, age, site of exposure, management site, medical outcome, recorded "related" respiratory depression ("respiratory rate <10 breaths/min and/or a SpO2 (pulse oximetry)<= 90%), reported administration of naloxone and intubation in oral exposure cases followed to known outcome. Concomitant products were also recorded in multiple-substance buprenorphine cases. Results 27,275 (11,010 multiple and 16,265 single) buprenorphine oral exposures were identified and followed to known outcome. A 65-fold increase in reported cases was reported over the study interval. A steady increase in the frequency of more serious outcomes by year was also observed. Respiratory depression occurred at a frequency of 11.8% (pediatric single-substance), 11.2% (pediatric multiple-substance), 11.3% (adult single-substance), and 11.9% (adult multiple-substance). Among oral exposures of buprenorphine and only one other product, benzodiazepines, opioids, ethanol, and amphetamines were most common. Conclusions Oral exposures have increased substantially between 2003 and 2019. More serious outcomes including deaths following oral exposures to buprenorphine have also increased over the same interval for both adult and pediatric patients. Clinically significant rates of respiratory depression in both adult and pediatric patients when taken alone and with additional substances were observed.
