Antibiotic prescribing by general dentists in the United States, 2013.

ABSTRACT: BACKGROUND:Dentists prescribe approximately 10% of outpatient antibiotics, but little is known about dentists' antibiotic prescribing patterns. The authors conducted a study to characterize prescribing by dentists according to antibiotic agent and category, patient demographic characteristics, and geographic region in the United States. METHODS:The authors identified oral antibiotic prescriptions dispensed during 2013 in the Xponent (QuintilesIMS) database. The authors used the total number of prescriptions and county-level census population denominators to calculate prescribing rates. In addition, the authors analyzed prescribing according to individual agent, drug category, and patient demographic characteristics and the total number of prescriptions calculated for general dentists overall. RESULTS:Dentists prescribed 24.5 million courses of antibiotics in 2013, a prescribing rate of 77.5 prescriptions per 1,000 people. Penicillins were the most commonly prescribed antibiotic category. Dentists prescribed most antibiotics for adults older than 19 years. The Northeast census region had the highest prescribing rate per 1,000 people. The District of Columbia had the highest prescribing rate of 99.5 per 1,000 people, and Delaware had the lowest prescribing rate of 50.7 per 1,000 people. CONCLUSIONS:Dentists prescribe large quantities of antibiotics in outpatient settings, and there is considerable geographic variability. Additional study is needed to better understand the reasons for this variability and identify areas of possible intervention and improvement. PRACTICAL IMPLICATIONS:Continued efforts to combat antibiotic resistance will require all prescribers, including dentists, to examine prescribing behaviors for appropriateness and the effectiveness of guidelines to identify opportunities to optimize antibiotic use.

Project description:BACKGROUND:The purpose of this study was to assess dental antibiotic prescribing trends over time, to quantify the number and types of antibiotics dentists prescribe inappropriately, and to estimate the excess health care costs of inappropriate antibiotic prescribing with the use of a large cohort of general dentists in the United States. METHODS:We used a quasi-Poisson regression model to analyze antibiotic prescriptions trends by general dentists between January 1, 2013, and December 31, 2015, with the use of data from Express Scripts Holding Company, a large pharmacy benefits manager. We evaluated antibiotic duration and appropriateness for general dentists. Appropriateness was evaluated by reviewing the antibiotic prescribed and the duration of the prescription. RESULTS:Overall, the number and rate of antibiotic prescriptions prescribed by general dentists remained stable in our cohort. During the 3-year study period, approximately 14% of antibiotic prescriptions were deemed inappropriate, based on the antibiotic prescribed, antibiotic treatment duration, or both indicators. The quasi-Poisson regression model, which adjusted for number of beneficiaries covered, revealed a small but statistically significant decrease in the monthly rate of inappropriate antibiotic prescriptions by 0.32% (95% confidence interval, 0.14% to 0.50%; P = .001). CONCLUSIONS:Overall antibiotic prescribing practices among general dentists in this cohort remained stable over time. The rate of inappropriate antibiotic prescriptions by general dentists decreased slightly over time. PRACTICAL IMPLICATIONS:From these authors' definition of appropriate antibiotic prescription choice and duration, inappropriate antibiotic prescriptions are common (14% of all antibiotic prescriptions) among general dentists. Further analyses with the use of chart review, administrative data sets, or other approaches are needed to better evaluate antibiotic prescribing practices among dentists.

Project description:Importance:The United States consumes most of the opioids worldwide despite representing a small portion of the world's population. Dentists are one of the most frequent US prescribers of opioids despite data suggesting that nonopioid analgesics are similarly effective for oral pain. While oral health and dentist use are generally similar between the United States and England, it is unclear how opioid prescribing by dentists varies between the 2 countries. Objective:To compare opioid prescribing by dentists in the United States and England. Design, Setting, and Participants:Cross-sectional study of prescriptions for opioids dispensed from outpatient pharmacies and health care settings between January 1 and December 31, 2016, by dentists in the United States and England. Data were analyzed from October 2018 to January 2019. Exposures:Opioids prescribed by dentists. Main Outcomes and Measures:Proportion and prescribing rates of opioid prescriptions. Results:In 2016, the proportion of prescriptions written by US dentists that were for opioids was 37 times greater than the proportion written by English dentists. In all, 22.3% of US dental prescriptions were opioids (11.4 million prescriptions) compared with 0.6% of English dental prescriptions (28?082 prescriptions) (difference, 21.7%; 95% CI, 13.8%-32.1%; P?<?.001). Dentists in the United States also had a higher number of opioid prescriptions per 1000 population (35.4 per 1000 US population [95% CI, 25.2-48.7 per 1000 population] vs 0.5 per 1000 England population [95% CI, 0.03-3.7 per 1000 population]) and number of opioid prescriptions per dentist (58.2 prescriptions per dentist [95% CI, 44.9-75.0 prescriptions per dentist] vs 1.2 prescriptions per dentist [95% CI, 0.2-5.6 prescriptions per dentist]). While the codeine derivative dihydrocodeine was the sole opioid prescribed by English dentists, US dentists prescribed a range of opioids containing hydrocodone (62.3%), codeine (23.2%), oxycodone (9.1%), and tramadol (4.8%). Dentists in the United States also prescribed long-acting opioids (0.06% of opioids prescribed by US dentists [6425 prescriptions]). Long-acting opioids were not prescribed by English dentists. Conclusions and Relevance:This study found that in 2016, dentists in the United States prescribed opioids with significantly greater frequency than their English counterparts. Opioids with a high potential for abuse, such as oxycodone, were frequently prescribed by US dentists but not prescribed in England. These results illustrate how 1 source of opioids differs substantially in the United States vs England. To reduce dental opioid prescribing in the United States, dentists could adopt measures similar to those used in England, including national guidelines for treating dental pain that emphasize prescribing opioids conservatively.
