Trajectories of opioid prescribing by dentists and OMFS analyzed to identify high prescribers
A study aiming to identify high prescribers by defining trajectories of opioid prescribing among dentists and oral and maxillofacial surgeons (OMFS) was presented at the 52nd Annual Meeting & Exhibition of the AADOCR, held in conjunction with the 47th Annual Meeting of the CADR. The AADOCR/CADR Annual Meeting & Exhibition took place at the Oregon Convention Center in Portland on March 15-18, 2023.
The study, conducted by Tumader Khouja of the University of Pittsburgh, used the IQVIA Longitudinal Prescription dataset to identify actively prescribing dentists and OMFS (≥20 prescriptions of any medication) from 2015-2019. Group-based trajectory models (GBTM) identified opioid prescribing trajectories based on annual prescribing rates (number of opioids/total number of prescriptions*100). Chi-square or Mann–Whitney U tests identified significant differences in characteristics by trajectory group.
The study found that from 2015-2019, 2,741,030 opioids were prescribed by 199,145 dentists/OMFS. GBTM identified 8 groups of prescribers. In group 1 (14.3% of prescribers), opioids composed <1% of all prescriptions. Groups 2, 3 and 4 (15.2%, 17.7% and 13.0% of prescribers, respectively) prescribed at low rates (2015=5.5%, 12.5% and 16.9%; 2019=1.5%, 4.4% and 11.9%, respectively). Group 5 (7.9% of prescribers) decreased prescribing by 82.7% (2015=29.4%; 2019=5.1%). Groups 6 and 7 (16.3% and 12.1% of prescribers) prescribed opioids at moderate rates (2015=28.7% and 39.2%; 2019=18.1% and 28.8%, respectively). Group 8 (3.5% of prescribers) consistently prescribed at high rates (2015=54.6%; 2019=44.7%). Within this high group, 4 trajectories were identified; 3 groups did not change their prescribing while 1 group (7.5% of high prescribers) rapidly declined prescribing. Compared with a combination of the 3 groups, the decliner group had more dentists (85.4% vs. 80.8%) and fewer OMFS (13.0% vs. 18.4%). At baseline, decliners had more Medicaid patients (2.5% vs. 1%) and a higher opioid prescribing rate (95.5 vs. 91.6 prescriptions/provider/100 patients, p<0.001 for all).
