Patterns of opioid prescribing by dentists in a pediatric population: a retrospective observational study

Abstract

BACKGROUND: Dentists are regular prescribers of opioid analgesic medications; however, there are few published data on their prescribing practices for children. The aim of this study was to assess opioid prescribing practices of dentists for pediatric patients. METHODS: We conducted a retrospective study (2011/12 to 2017/18) using administrative health data of opioid prescribing practices of dentists in Nova Scotia for children and adolescents (age < 18 yr). The main variables of interest were opioid "type" and "load" dentists prescribed (number of dispensed prescriptions/yr, days supplied/prescription and dosage/d per prescription in milligrams of morphine equivalents [MME]). RESULTS: Dentists accounted for a mean of 18.3% (standard deviation 1.5%) of all opioid prescribers for the pediatric population annually but were responsible for 59.9% of all opioid prescriptions and 48.6% of total MME dispensed during the 7-year study period. Oral and maxillofacial surgeons were responsible for 80.7% of all dental-related opioids dispensed. Codeine was most frequently prescribed (78.6% of total MME), followed by oxycodone (11.1%). There were significant downward trends over the study period in the total amount of opioid analgesics dispensed (r = -0.903, p < 0.01), primarily due to a reduction in the total amount of codeine dispensed and number of days supplied per prescription (r = -0.837, p < 0.05). Few opioids were dispensed to children less than 12 years. INTERPRETATION: Dentists in Nova Scotia reduced prescriptions of opioids in the pediatric population between 2011/12 and 2017/18, which may indicate that current opioid prescribing principles are influencing dentists' prescribing habits. Nonetheless, patients and parents should receive appropriate counselling as to the proper use, risks, storage and potential for misuse of opioids when prescribed.
