Prescribing patterns of opioid analgesics in a dental setting: 2013-2018

Objective. Analgesic prescribing patterns are influenced by internal and external factors. Understanding these factors could help improve prescribing practices. Study Design. We conducted a retrospective analysis of electronic health records with regard to analgesic prescriptions written from 2013 through 2018 at the University of Kentucky College of Dentistry. Deidentified information (age, gender, dental proce-dures, analgesic drug, quantity, and refills) were recorded and studied with respect to national guidelines and recent state legislation using the chi(2) test, analysis of variance, logistic regression, and multiple linear regression. Results. Opioids comprised 74.9% of the 17,099 analgesic prescriptions written. Extractions were most commonly associated with opioid prescriptions. Multivariate analysis showed that (1) older patients were more likely to receive an opioid prescription (P < .01) but with fewer pills (P < .01); (2) surgical extractions were associated with a lower opioid prescription rate (P < .01) but more opioid pills per prescription compared with nonsurgical extractions (P < .01); and (3) the odds of receiving an opioid prescription and the number of opioid pills prescribed decreased over year after release of the national guideline (P < .01) and after enactment of state legislation (P < .01). Conclusions. Regulations and guidelines were associated with reduction in opioid prescriptions.
