Dentists' prescribing of antibiotics and opioids to Medicare Part D beneficiaries: Medications of high impact to public health

Mapping Worldwide Antibiotic Use in Dental Practices: A Scoping Review

Antibiotic resistance is a critical issue today, necessitating the monitoring of antibiotic usage across various sectors. To determine the defined daily doses (DDDs) of antibiotics prescribed by dentists globally, a comprehensive search was conducted in PubMed, ProQuest, ScienceDirect, Web of Science, Scopus, and EBSCOhost, resulting in the inclusion of 15 documents in this scoping review. The DDD per 1000 inhabitants per day (DID) for oral antibiotics prescribed by dentists for the studied countries was generally below 2.11, with the exception of South Korea, which had a DDD per 1000 patients per day (DPD) of less than 6.97. Most countries, except Croatia and Belgium, demonstrated a decreasing trend in DID before the COVID-19 pandemic, but restrictions during the pandemic led to an increase in these numbers. Penicillin-derived antibiotics were the most commonly prescribed antibiotic among dentists in most countries. This study highlights significant gaps and missing data regarding antibiotics prescribed by dentists worldwide. However, it also indicates that the publication of guidelines, education, and evaluation of antibiotic use can lead to more controlled and appropriate prescriptions among dental professionals.

Alternatives to β-Lactams as Agents for the Management of Dentoalveolar Abscess

Dentoalveolar abscess are localized infections within the tooth or the surrounding alveolar bone, often resulting from untreated dental caries or dental trauma causing alveolar bone resorption or even loss. Serious consequences arising from the spread of a dental abscess can often lead to significant morbidity and mortality. The acute dentoalveolar abscess is a polymicrobial infection comprising strict anaerobes, such as anaerobic cocci i.e., Prevotella fusobacterium species, and facultative anaerobes i.e., Streptococci viridians and Streptococcus anginosus. Moreover, inappropriately managed dental infections can progress to severe submandibular space infections with associated serious complications, such as sepsis and airway obstruction. An audit of the Hull Royal Infirmary between 1999 and 2004 showed an increase in the number of patients presenting to oral and maxillofacial surgery services with dental sepsis. Thus, the scientific community is forced to focus on treatment strategies for the management of dentoalveolar abscess (DAA) and other related dental problems. The current treatment includes antibiotic therapy, including β-lactams and non-β- lactams drugs, but it leads to the development of resistant microorganisms due to improper and wide usage. Furthermore, the currently used β-lactam therapeutics is non-specific and easily hydrolyzed by the β-lactamase enzymes. Thus, the research focused on the non-β-lactams that can be the potential pharmacophore and helpful in the management of DAA, as the appropriate use and choice of antibiotics in dentistry plays an important role in antibiotic stewardship. The newer target for the choice is NLRP inflammasome, which is the major chemical mediator involved in dental problems. This review focused on pathogenesis and current therapeutics for the treatment of dentoalveolar abscesses.

Association between the COVID-19 outbreak and opioid prescribing by U.S. dentists

BACKGROUND

U.S. data on opioid prescribing by dentists are limited to 2019. More recent data are needed to understand the effect of the COVID-19 outbreak on dental opioid prescribing, characterize current practices, and determine if dental opioid stewardship initiatives are still warranted.

OBJECTIVE

To evaluate the association between the COVID-19 outbreak and the rate of opioid prescribing by U.S. dentists.

METHODS

During February-April 2023, the authors conducted a cross-sectional analysis of the IQVIA Longitudinal Prescription Database, which reports 92% of prescriptions dispensed in U.S. retail pharmacies. The authors calculated the monthly dental opioid dispensing rate, defined as the monthly number of dispensed opioid prescriptions from dentists per 100,000 U.S. individuals, during January 2016-February 2020 and June 2020-December 2022. To prevent distortions in trends, data from March-May 2020, when dental opioid dispensing declined sharply, were excluded. Using linear segmented regression models, the authors assessed for level and slope changes in the dental opioid dispensing rate during June 2020.

RESULTS

Analyses included 81,189,605 dental opioid prescriptions. The annual number of prescriptions declined from 16,105,634 in 2016 to 8,910,437 in 2022 (-44.7%). During January 2016-February 2020, the dental opioid dispensing rate declined -3.9 (95% CI: -4.3, -3.6) per month. In June 2020, this rate abruptly increased by 31.4 (95% CI: 19.3, 43.5) and the monthly decline in the dental opioid dispensing rate slowed to -2.1 (95% CI: -2.6, -1.6) per month. As a result, 6.1 million more dental opioid prescriptions were dispensed during June 2020-December 2022 than would be predicted had trends during January 2016-February 2020 continued.

DISCUSSION

U.S. dental opioid prescribing is declining, but the rate of this decline slowed after the COVID-19 outbreak. Findings highlight the continued importance of dental opioid stewardship initiatives.

Comparison of guideline concordant antibiotic prophylaxis in Veterans Affairs and non-Veterans Affairs dental settings among those with cardiac conditions or prosthetic joints

BACKGROUND

No research has been conducted to assess whether antibiotic prophylaxis prescribing differs by dental setting. Therefore, the goal of this study was to compare the prescribing of antibiotic prophylaxis in Veterans Affairs (VA) and non-Veterans Affairs settings.

METHODS

This was a retrospective study of veteran and non-veteran dental patients with cardiac conditions or prosthetic joints between 2015-2017. Multivariable log binomial regression analysis was conducted to compare concordant prescribing by setting with a sub-analysis for errors of dosing based on antibiotic duration (i.e., days prescribed).

RESULTS

A total of 61,124 dental visits that received a prophylactic antibiotic were included. Most were male (61.0%), and 55 years of age or older (76.2%). Nearly a third (32.7%) received guideline concordant prophylaxis. VA dental settings had a lower prevalence of guideline concordant prescribing compared to non-VA settings in unadjusted results (unadjusted prevalence ratio [uPR] = 0.92, 95% CI: 0.90-0.95). After adjustment, prevalence of guideline concordant prescribing was higher in those with prosthetic joints in the VA setting (adjusted prevalence ratio [aPR] = 1.73, 95% CI: 1.59-1.88), with no difference identified in those without a prosthetic joint (aPR = 0.99, 95% CI: 0.96-1.01). Concordance of dosing was higher in VA compared to non-VA settings (aPR = 1.11, 95% CI: 1.07-1.15).

CONCLUSIONS

VA has a higher prevalence of guideline concordant prescribing among those with prosthetic joints and when assessing dosing errors. Though the presence of an integrated electronic health record (EHR) may be contributing to these differences, other system or prescriber-related factors may be responsible. Future studies should focus on to what extent the integrated EHR may be responsible for increased guideline concordant prescribing in the VA setting.

Opioid Prescribing by Dentists in the Veterans Health Administration

INTRODUCTION

Nonopioid analgesics are more effective for most oral pain, but data suggest that dental prescribing of opioids is excessive. This study evaluates the extent to which opioids exceed recommendations and the characteristics associated with opioid overprescribing by Veterans Health Administration dentists.

METHODS

This was a national cross-sectional study of Veterans' dental visits from 2015 to 2018. Overprescribing was defined per national guidelines as >120 morphine milligram equivalents (primary outcome). The association of dental visit and patient demographic and medical characteristics was modeled with overprescribing (defined as >120 morphine milligram equivalents) using Poisson regression with clustering by facility and patient. A secondary analysis assessed opioid prescriptions >3 days' supply. The dates of analysis were January 2020‒May 2021.

RESULTS

Of the 196,595 visits, 28.7% exceeded 120 morphine milligram equivalents. Friday visits and people with chronic oral pain or substance misuse were associated with a higher prevalence of overprescribing. Women, older Veterans, and Black and Latinx Veterans were less likely to be overprescribed than men, younger Veterans, and White Veterans, respectively. Routine dental visits had a higher prevalence of opioid overprescribing than invasive visits. Opioid overprescribing decreased over time. White Veterans were more likely to receive oxycodone and hydrocodone, whereas people of Black race and Latinx ethnicity were more likely to receive codeine and tramadol. In the secondary analysis, 68.5% of opioid prescriptions exceeded a 3-day supply.

CONCLUSIONS

Nearly 1 in 3 opioids prescribed by Veterans Health Administration dentists exceed guidelines. Prescribing higher potency and quantities of opioids, especially on Fridays and to certain demographic groups, should be addressed as part of dental opioid stewardship programs.

Efficacy of oxycodone for postoperative dental pain: A systematic review and meta-analysis

OBJECTIVES

Dental pain is a commonly managed presentation in medicine and dentistry, where oxycodone is often prescribed. The aim of this systematic review and meta-analysis was to determine and quantify the effectiveness of oxycodone for acute dental pain.

DATA

Randomised controlled trials, controlled trials and comparative studies were included involving patients >12 years, where oxycodone was trialled for dental pain.

SOURCES

Three databases were searched: Medline Ovid, Embase Ovid and Web of Science. Two authors independently screened title and abstracts for relevance, extracted data and performed bias assessments.

STUDY SELECTION

Of 148 potentially relevant studies, 13 articles met the inclusion criteria for the systematic review and of the 13, nine studies were included in the meta-analysis. All studies were single-dose analgesia for surgical third molar extractions.

CONCLUSIONS

Oxycodone produced more effective analgesia in combination with paracetamol. In the meta-analysis, monotherapy etoricoxib and rofecoxib showed significant pain relief compared to combination oxycodone/paracetamol (SPID6 mean difference=-2.13, CI=-3.29, -0.98; TOTPAR6 mean difference=-2.98, CI=-4.90, -1.06). Non-steroidal anti-inflammatory drugs (NSAIDs) were more effective than oxycodone/paracetamol combinations, however, the evidence would become weak in a future study with a similar patient setting due to substantial statistical heterogeneity (SPID6 and TOTPAR6 prediction interval -4.471, 0.207 and -7.28, 1.32 respectively).

CLINICAL SIGNIFICANCE

Non-steroidal anti-inflammatory drugs were superior than oxycodone/paracetamol combinations, although some patient populations may experience similar effects to the combined oxycodone/paracetamol combination.

Antibiotic prophylaxis prescriptions prior to dental visits in the Veterans' Health Administration (VHA), 2015-2019

OBJECTIVE

To determine prophylaxis appropriateness by Veterans' Affairs (VA) dentists.

DESIGN

A cross-sectional study of dental visits, 2015-2019.

METHODS

Antibiotics within 7 days before a visit in the absence of an oral infection were included. Appropriate antibiotic prophylaxis was defined as visits with gingival manipulation and further delineated into narrow and broad definitions based on comorbidities. The primary analysis applied a narrow definition of appropriate prophylaxis: cardiac conditions at the highest risk of an adverse outcome from endocarditis. The secondary analysis included a broader definition: cardiac or immunocompromising condition or tooth extractions and/or implants. Multivariable log-linear Poisson generalized estimating equation regression was used to assess the association between covariates and unnecessary prophylaxis prescriptions.

RESULTS

In total, 358,078 visits were associated with 369,102 antibiotics. The median prescription duration was 7 days (IQR, 7-10); only 6.5% were prescribed for 1 day. With the narrow definition, 15% of prophylaxis prescriptions were appropriate, which increased to 72% with the broader definition. Prophylaxis inconsistent with guidelines increased over time. For the narrow definition, Black (vs White) race, Latine (vs non-Latine) ethnicity, and visits located in the West census region were associated with unnecessary prophylaxis. Variables associated with a lower risk were older age, prosthetic joints, immunocompromising condition, and rural location.

CONCLUSIONS

Of every 6 antibiotic prophylaxis prescriptions, 5 were inconsistent with guidelines. Improving prophylaxis appropriateness and shortening duration may have substantial implications for stewardship. Guidelines should state whether antibiotic prophylaxis is indicated for extractions, implants, and immunocompromised patients.

Opioid Prescription Trends in a US Dental School Clinic, 2014-2018: A Retrospective Study Using Electronic Health Record Data

OBJECTIVES

Opioid misuse and abuse continues to be a grave public health concern in the United States. The aim of this study was to use electronic health records (EHRs) from a US dental school clinic to retrospectively analyze trends in opioid prescription frequencies.

DESIGN

A database review was conducted using EHR data from 20 patient care clinics in a dental school over a 5-year period during which local, state, and national policies and guidelines to mitigate harm from opioid misuse were introduced.

SETTING

University of Michigan School of Dentistry, state of Michigan.

OUTCOME MEASURE

Descriptive statistics using measures of frequency and distribution of opioid prescriptions written were compared over a 5-year period by dental school clinic specialty, CDT (Code on Dental Procedures and Nomenclature) procedure, drug type, and patient age/gender.

RESULTS

From 2014 to 2018, a total of 12 401 opioid-based prescriptions were written by dental providers in the school's patient care clinics. An ARIMA (autoregressive integrated moving average) model time trend analysis demonstrated a significant decrease in the number of prescribed opioids after 2016.

CONCLUSIONS

While causal relationships cannot be drawn between drug abuse and prescription trends alone, this exploratory study provided a better understanding of prescription frequency patterns that can help monitor distribution of opioids and identify areas where future public health interventions may be needed. Dental education institutions have an obligation to ensure a competent health care workforce as well as unique opportunities to support regional and national public health strategies aimed at reducing misuse of opioids.

Outpatient Prescribing of Antibiotics and Opioids by Veterans Health Administration Providers, 2015-2017

INTRODUCTION

Antibiotics and opioids are targeted by public health and stewardship communities for reductions in prescribing across the country. This study evaluates trends and factors associated with outpatient prescribing by dental and medical providers in a large integrated health system.

METHODS

This was a cross-sectional study of national dental and medical outpatient visits from Department of Veterans Affairs facilities in 2015-2017; analyzed in 2019-2020. Antibiotic and opioid prescribing rates were assessed by provider and facility characteristics. Multivariable Poisson regression adjusted for repeated measures by the provider was used to assess the independent association between facility and provider characteristics and rate of prescribing.

RESULTS

Over the study period, 4,625,840 antibiotic and 10,380,809 opioid prescriptions were identified for 115,625,890 visits. Physicians prescribed most antibiotics (67%). Dentists prescribed 6% of the antibiotics but had the highest per-visit antibiotic prescribing rate compared to medical providers (6.75 vs 3.90 prescriptions per 100 visits, p<0.0001), which was largely driven by dental specialists. By contrast, dentists had lower opioid prescribing than medical providers (3.02 vs 9.20 prescriptions per 100 visits, p<0.0001). Overall, antibiotic and opioid prescribing decreased over time, with opioids having the greatest decreases (-28.0%). In multivariable analyses, U.S. geographic region, rurality, and complexity were associated with prescribing for both drug classes. Opioid and antibiotic prescribing were positively correlated.

CONCLUSIONS

Although antibiotic and opioid prescribing has decreased, there are still important target areas for improvement. Interventions need to be tailored to community characteristics such as rurality and provider type.

Non-Visit-Based and Non-Infection-Related Antibiotic Use in the US: A Cohort Study of Privately Insured Patients During 2016-2018

BACKGROUND

Ambulatory antibiotic prescriptions without a clinic visit or without documentation of infection could represent overuse and contribute to adverse outcomes. We aim to describe US ambulatory antibiotic prescribing, including those without an associated visit or infection diagnosis.

METHODS

We conducted an observational cohort study using data of all patients receiving antibacterial, antibiotic prescriptions from 04/01/2016 to 06/30/2018 in a large US private health insurance plan. We identified outpatient antibiotic prescriptions as (1) associated with a clinician visit and an infection-related diagnosis; (2) associated with a clinician visit but no infection-related diagnosis; or (3) not associated with an in-person clinician visit in the 7 days before the prescription (non-visit-based). We then assessed whether non-visit-based antibiotic prescriptions (NVBAPs) differed from visit-based antibiotics by patient, clinician, or antibiotic characteristics using multivariable models.

RESULTS

The cohort included 8.6M enrollees who filled 22.3M antibiotic prescriptions. NVBAP accounted for 31% (6.9M) of fills, and non-infection-related prescribing accounted for 22% (4.9M). NVBAP rates were lower for children than for adults (0-17 years old, 16%; 18-64 years old, 33%; >65 years old, 34%). Among most commonly prescribed antibiotic classes, NVBAP was highest for penicillins (36%) and lowest for cephalosporins (25%) and macrolides (25%). Specialist physicians had the highest rate of NVBAP (38%), followed by internists (28%), family medicine (20%), and pediatricians (10%). In multivariable models, NVBAP was associated with increasing age, and NVBAP was less likely for patients in the South, those with more baseline clinical visits, or those with chronic lung disease.

CONCLUSIONS

Over half of ambulatory antibiotic use was either non-visit-based or non-infection-related. Particularly given health care changes due to the coronavirus disease 2019 pandemic, efforts to improve antibiotic prescribing must account for non-visit-based and non-infection-related prescribing.

Post-operative pain management in dental implant surgery: a systematic review and meta-analysis of randomized clinical trials

PURPOSE

To evaluate the clinical efficacy of various analgesic medications in mitigating orofacial pain following dental implant surgery.

MATERIALS AND METHODS

A systematic search was conducted to identify randomized controlled clinical trials (RCTs). The primary outcomes examined were post-operative pain (POP) and consumption of rescue analgesics following implant placement; secondary outcomes included adverse effects, post-operative inflammation, infection, swelling, bleeding, patient satisfaction, and quality of life. Random effects meta-analysis was conducted for risk ratios of dichotomous data.

RESULTS

Nine RCTs fulfilled the eligibility criteria. Individual studies and meta-analysis of two studies indicated that nonsteroidal anti-inflammatory drugs (NSAIDs) significantly reduced POP and consumption of rescue analgesics after dental implant placement compared to placebo. Transdermal administration of NSAIDs may be superior to the oral route as it was similarly effective for POP control and resulted in fewer side effects. Glucocorticoids administered as primary analgesics or NSAID adjuvants resulted in comparable pain sensation compared to NSAIDs alone. Caffeine-containing analgesics were reported as acceptable and effective for the treatment of POP and swelling when compared to codeine adjuvants. With regard to analgesic dosing schedules, pain modulation may be most critical during the first 72 h following dental implant placement. Risk of bias assessment indicated an overall low risk of bias across the included trials.

CONCLUSION

Within the limitations of this review, POP following implant surgery may be effectively treated with the short-term use of analgesic medications. However, given the heterogeneity in the available RCTs, there is insufficient evidence to recommend an analgesic regimen following dental implant surgery.

CLINICAL RELEVANCE

Short-term use of analgesic medications may be sufficient for post-operative pain management in dental implant surgery. Ultimately, the clinician's analgesic prescription should be directed by a patient's medical history, in order to increase the success of pain management in a short period of time and decrease potential adverse effects.

Antibiotic Therapy in Dentistry

Dental caries, pulpal necrosis, trauma, and periodontal diseases can result in dental infections which could have severe consequences that affect both soft and hard tissues of the oral cavity. Dental infections commonly present with symptoms of pain, fever, and swelling. Surgical and endodontic treatments are the early management of infected teeth, followed by antibiotic therapy. Some alternative methods also exist for treating infection such as low-level laser therapy and photodynamic therapy. Antibiotics are generally used in dental procedures to treat odontogenic infections, nonodontogenic infections, local infection, focal infection, and prophylaxis. Antibiotic prophylaxis is prescribed for patients with immunosuppressed conditions, infective endocarditis, metabolic disorders, and patients with prosthetic joints. To reduce the complications of unnecessary antibiotic prescriptions especially bacterial resistance, comprehensive guidelines should be established. It has been noted that only about 12% of dentists adequately and correctly prescribe antibiotics, which shows the importance of comprehensive guidelines. Antibiotics prescription may result in some adverse effects such as hypersensitivity reactions and dermatological and allergic disorders. Furthermore, unnecessary prescription of antibiotics could result in several serious sequelae, for example, bacterial resistance, gastric and hematological problems, and diversion of bacterial microbiota. The present review attempts to summarize the indications of antibiotic therapy in dentistry and discuss the common types of antibiotics that are routinely used in dental practice based on pharmacologic classes. Moreover, types of antibiotics that are considered safe during pregnancy and childhood are also reviewed.

Prophylactic antibiotic prescribing in dental practice: Findings from a National Dental Practice-Based Research Network questionnaire

BACKGROUND

Little is known about antibiotic prescribing practices of dentists. The objective of this study was to gain a better understanding of dentists' beliefs and behaviors regarding the use of antibiotic prophylaxis (AP) before invasive dental procedures.

METHODS

A multidisciplinary team developed and disseminated a questionnaire to 3,584 dentist members of the National Dental Practice-Based Research Network.

RESULTS

Overall, 2,169 network dentists (61%) responded. Respondents saw patients at risk of developing infective endocarditis (IE) and prosthetic joint infection (PJI) at least once per week (35% and 65%, respectively). Although 78% of dentists agreed that the 2007 American Heart Association guidelines for the prevention of IE are well-defined and clear, only 49% agreed concerning PJI guidelines. Differences for the IE and PJI patient populations also existed for questions regarding dentists' understanding of the specific patient groups at risk, the recommended antibiotic regimens, and the need to consult with a patient's cardiologist or orthopedic surgeon.

CONCLUSIONS

The survey results indicate that decision making regarding the use of AP occurs frequently among dentists. Moreover, dentists reported uncertainty about the appropriate use of AP as defined by both IE and PJI guidelines, which may have resulted in a lack of concordance between dentists' beliefs and their practice behaviors.

PRACTICAL IMPLICATIONS

The results reported by the authors highlight the need to develop better educational programs that address antimicrobial stewardship in AP for patients at risk of developing IE and PJI and target the dental profession.

Improvement of dental prescribing practices using education and a prescribing tool: A pilot intervention study

AIMS

Antibiotic resistance is a global public health problem. Around 55% of dental antibiotic prescribing is deemed inappropriate. The aim of this multimodal interventional pilot study was to assess the effect on prescribing of education and a dentally designed prescribing website.

METHODS

Twenty-six dentists were recruited for the 12-week study using a pre-post design. Dentists self-recorded their prescribing of antibiotics, analgesics and anxiolytics for 6 weeks. After dentists were provided education and website access, they recorded their prescribing for a further 6 weeks. Four outcomes were measured comparing the prescribing before and after the intervention: (i) the number of inappropriate indications for which antibiotics were prescribed; (ii) the number of prescriptions; (iii) accuracy of the prescriptions according to the Australian therapeutic guidelines; and (iv) the confidence of practitioners towards the prescribing website. Participants were interviewed for feedback.

RESULTS

There was a substantial reduction of 44.6% in the number of inappropriate indications for which antibiotics were prescribed after the intervention and a decrease of 40.5% in the total number of antibiotics. Paracetamol with codeine substantially reduced by 56.8%. For the 3 most commonly prescribed antibiotics (amoxicillin, phenoxymethylpenicillin and metronidazole), there was the improvement in the accuracy of the prescriptions ranging from 0-64.7 to 74.2-100%.

CONCLUSION

This pilot study showed the intervention of targeted education and the prescribing tool was effective in improving dental prescribing, knowledge and confidence of practitioners, as well as providing an effective antibiotic stewardship tool. This context-specific intervention shows substantial promise for implementation into dental practice.

Prescribing patterns in a US dental school from 2010 to 2017

OBJECTIVE

Dental education has an essential role in helping combat the opioid and antibiotic resistance crises. This study evaluates the prescribing practices of clinical instructors, advanced graduate residents, and predoctoral students in an academic dental setting.

METHODS

A retrospective chart review was conducted of electronic dental records from the years 2010 to 2017. The proportions of prescriptions for each drug group was calculated by prescribers' training level and specialty. Descriptive statistics were calculated for the daily opioid Morphine Milligram Equivalent (MME) dose prescribed across years and provider characteristics.

RESULTS

Over the 8 years, 65,160 prescriptions were written for 10,374 patients by 625 prescribers. The most commonly prescribed drugs were for fluoride-based medications (30%) and antibiotics (24%). Periodontists had the greatest absolute number of opioid analgesics prescriptions (n = 2712); oral maxillofacial surgeons (OMFS) prescribed more opioids than other classes of drug (49%) as a proportion of within-specialty prescriptions. Antibiotics were the most common drugs prescribed by endodontists (46%) and second most common drugs prescribed by periodontists (25%), OMFS (28%), and prosthodontists (21%). From 2010 to 2017, the proportion of prescriptions for antibiotics remained unchanged, while that of fluoride-based drugs increased from 2010 to 2014 and plateaued thereafter. The proportion of prescriptions for opioid analgesics decreased from 18% to 7%. The median daily MME dose across year and provider characteristics stayed constant (<50 MME).

CONCLUSION

These results demonstrate encouraging prescription trends for opioid and fluoride-based drugs. Due to the high prevalence of antibiotic prescriptions in academic dental settings, stewardship approaches should be emphasized.

Opioid prescribing patterns after dental visits among beneficiaries of Medicaid in Washington state in 2014 and 2015

BACKGROUND

Dentists contribute to the prevailing opioid epidemic in the United States. Concerning the population enrolled in Medicaid, little is known about dentists' opioid prescribing.

METHODS

The authors performed a retrospective cohort study of beneficiaries of Medicaid in Washington state with dental claims in 2014 and 2015. The primary outcome was the proportion of dental visits associated with an opioid prescription. The authors categorized visits as invasive or noninvasive by using procedure codes and each beneficiary as being at low or high risk by using his or her prescription history from the prescription drug monitoring program.

RESULTS

A total of 126,660 (10.3%) of all dental visits, most of which were invasive (66.9%), among the population enrolled in Medicaid in Washington state was associated with opioid prescriptions. However, noninvasive dental visits and visits for beneficiaries who had prior high-risk prescription use were associated with significantly higher mean days' supply and mean quantity of opioids prescribed. Results from the multivariate logistic regression showed that the probability of having an opioid-associated visit increased by 35.6 percentage points when the procedures were invasive and by 11.1 percentage points when the beneficiary had prior high-risk prescription use.

CONCLUSIONS

This baseline of opioid prescribing patterns after dental visits among the population enrolled in Medicaid in Washington state in 2014 and 2015 can inform future studies in which the investigators examine the effect of policies on opioid prescribing patterns and reasons for the variability in the dosage and duration of opioid prescriptions associated with noninvasive visits.

PRACTICAL IMPLICATIONS

Dentists must exercise caution when prescribing opioids during invasive visits and to patients with prior high-risk prescription use.

Is it time US dentistry ended its opioid dependence?

BACKGROUND

In 2017, 11.4 million US citizens misused prescription opioids, resulting in 46 overdose deaths daily and a $78.5 billion burden on the economy. Dentists are one of the most frequent prescribers of opioids, and there is concern that dental prescribing is contributing to the opioid crisis.

METHODS

A 2019 study showed 22.3% of US dental prescriptions were for opioids compared with 0.6% of dental prescriptions in England where nonsteroidal anti-inflammatory drugs (NSAIDs) and acetaminophen accounted for most analgesic prescriptions. This observation prompted a review of international analgesic prescribing habits and of the advantages and disadvantages of opioids and NSAIDs for treating dental pain.

RESULTS

US opioid prescribing far exceeded that in other countries where NSAIDs accounted for most dental analgesic prescribing. Furthermore, results from reviews published respectively in 2018 and 2016 help confirm that NSAIDs and NSAID-acetaminophen combinations are as effective as or more effective than opioids for controlling dental pain and cause significantly fewer adverse effects.

CONCLUSIONS

In light of the potential for misuse and evidence that NSAIDs are as effective as opioids and have fewer adverse effects, there is clear patient benefit in avoiding opioids for the prevention or management of dental pain.

PRACTICAL IMPLICATIONS

A growing preponderance of evidence shows that opioids are not needed for routine oral health care. This article provides an overview of the evidence and outlines possible pain management models to minimize opioid use in dentistry. The purpose is to stimulate debate about this important topic and encourage the development of definitive guidance by professional bodies, health care providers, and state and federal agencies.

A survey of prescribing practices by general dentists in Australia

BACKGROUND

Numerous studies of dental antibiotic prescribing show that overprescribing is a worldwide occurrence. The aim of this study was to assess prescribing practices of general dentists in Australia for antibiotics, analgesics and anxiolytics and to determine the extent to which prescribing is in accordance with current guidelines.

METHODS

A structured questionnaire was sent to 1468 dentists in Victoria and Queensland in July-August 2018. The questionnaire covered demographics, clinical conditions where dentists prescribe antibiotics, non-clinical factors which influence prescribing, and medicines for anxiolysis and pain relief. Responses were scored using a system based on the current Australian therapeutic guidelines. Logistic regression was used to determine the relative importance of independent variables on inappropriate prescribing.

RESULTS

Three hundred eighty-two responses were received. Overall, 55% of overprescribing of antibiotics was detected, with a range of 13-88% on a routine or occasional basis depending on the scenario. Between 16 and 27% of respondents inappropriately preferenced analgesics over anti-inflammatories for dental pain; 46% of those who prescribed anxiolytic medicines did so inappropriately, with varying regimens and choices outside the guidelines. Years of practice was the main demographic factor influencing prescribing, with recent graduates (0-5 years) generally scoring better than their colleagues for antibiotic prescribing (p < 0.05).

CONCLUSIONS

Future interventions could be directed towards the appropriate role and use of antibiotics, shortfalls in knowledge and appropriate choices of medicines for pain relief and anxiolysis. Given that the most overprescribing occurred for localised swellings (88%), this area could be focused on in continuing education as well as ensuring it is addressed in undergraduate teaching. Continuing education on the appropriate use of medicines can be targeted at more experienced dentists as well as patients, especially those who expect antibiotics instead of treatment.

Annual review of selected scientific literature: A report of the Committee on Scientific Investigation of the American Academy of Restorative Dentistry

This comprehensive review of the 2018 dental literature is provided to inform busy dentists about progress in the profession. Developed by the Committee on Scientific Investigation of the American Academy of Restorative Dentistry, each author brings discipline-specific expertise to one of the 8 sections of the report including (1) prosthodontics; (2) periodontics, alveolar bone, and peri-implant tissues; (3) implant dentistry; (4) dental materials and therapeutics; (5) occlusion and temporomandibular disorders; (6) sleep-related breathing disorders; (7) oral medicine and oral and maxillofacial surgery; and (8) dental caries and cariology. The report targets important information that will likely influence day-to-day treatment decisions. Each review is not intended to stand alone but to update interested readers so that they may visit source materials if greater detail is desired. As the profession continues its march toward evidence-based clinical decision-making, an already voluminous library of potentially valuable dental literature continues to grow. It is the intention of this review and its authors to provide assistance in navigating the extensive dental literature published in 2018. It is our hope that readers find this work useful in the clinical management of patients moving forward.

Assessment of the Appropriateness of Antibiotic Prescriptions for Infection Prophylaxis Before Dental Procedures, 2011 to 2015

Importance

Antibiotics are recommended before certain dental procedures in patients with select comorbidities to prevent serious distant site infections.

Objective

To assess the appropriateness of antibiotic prophylaxis before dental procedures using Truven, a national integrated health claims database.

Design, Setting, and Participants

Retrospective cohort study. Dental visits from 2011 to 2015 were linked to medical and prescription claims from 2009 to 2015. The dates of analysis were August 2018 to January 2019. Participants were US patients with commercial dental insurance without a hospitalization or extraoral infection 14 days before antibiotic prophylaxis (defined as a prescription with ≤2 days' supply dispensed within 7 days before a dental visit).

Exposures

Presence or absence of cardiac diagnoses and dental procedures that manipulated the gingiva or tooth periapex.

Main Outcomes and Measures

Appropriate antibiotic prophylaxis was defined as a prescription dispensed before a dental visit with a procedure that manipulated the gingiva or tooth periapex in patients with an appropriate cardiac diagnosis. To assess associations between patient or dental visit characteristics and appropriate antibiotic prophylaxis, multivariable logistic regression was used. A priori hypothesis tests were performed with an α level of .05.

Results

From 2011 to 2015, antibiotic prophylaxis was prescribed for 168 420 dental visits for 91 438 patients (median age, 63 years; interquartile range, 55-72 years; 57.2% female). Overall, these 168 420 dental visits were associated with 287 029 dental procedure codes (range, 1-14 per visit). Most dental visits were classified as diagnostic (70.2%) and/or preventive (58.8%). In 90.7% of dental visits, a procedure was performed that would necessitate antibiotic prophylaxis in high-risk cardiac patients. Prevalent comorbidities include prosthetic joint devices (42.5%) and cardiac conditions at the highest risk of adverse outcome from infective endocarditis (20.9%). Per guidelines, 80.9% of antibiotic prophylaxis prescriptions before dental visits were unnecessary. Clindamycin was more likely to be unnecessary relative to amoxicillin (odds ratio [OR], 1.10; 95% CI, 1.05-1.15). Prosthetic joint devices (OR, 2.31; 95% CI, 2.22-2.41), tooth implant procedures (OR, 1.66; 95% CI, 1.45-1.89), female sex (OR, 1.21; 95% CI, 1.17-1.25), and visits occurring in the western United States (OR, 1.15; 95% CI, 1.06-1.25) were associated with unnecessary antibiotic prophylaxis.

Conclusion and Relevance

More than 80% of antibiotics prescribed for infection prophylaxis before dental visits were unnecessary. Implementation of antimicrobial stewardship in dental practices is an opportunity to improve antibiotic prescribing for infection prophylaxis.

Successful Implementation of an Antibiotic Stewardship Program in an Academic Dental Practice

BACKGROUND

Most antibiotic use in the United States occurs in the outpatient setting, and 10% of these prescriptions are generated by dentists. The development of comprehensive antibiotic stewardship programs (ASPs) in the dental setting is nascent, and therefore we describe the implementation of a dental ASP.

METHODS

A collaborative team of dentist, pharmacist, and physician leaders conducted a baseline needs assessment and literature evaluation to identify opportunities to improve antibiotic prescribing by dentists within Illinois' largest oral health care provider for Medicaid recipients. A multimodal intervention was implemented that included patient and provider education, clinical guideline development, and an assessment of the antibiotic prescribing rate per urgent care visit before and after the educational interventions.

RESULTS

We identified multiple needs, including standardization of antibiotic prescribing practices for patients with acute oral infections in the urgent care clinics. A 72.9% decrease in antibiotic prescribing was observed in urgent care visits after implementation of our multimodal intervention (preintervention urgent care prescribing rate, 8.5% [24/283]; postintervention, 2.3% [8/352]; P < .001).

CONCLUSIONS

We report the successful implementation of a dental ASP that is concordant with the Centers for Disease Control and Prevention Core Elements of Antibiotic Stewardship in the Outpatient Setting. Our approach may be adapted to other dental practices to improve antibiotic prescribing.
