Dental opioid prescribing and multiple opioid prescriptions among dental patients: Administrative data from the South Carolina prescription drug monitoring program

Trends in dispensed prescriptions for opioids, sedatives, benzodiazepines, gabapentin, and stimulants to children by general dentists, 2012-2019

PURPOSE

Opioids, benzodiazepines and sedatives can manage dental pain, fear and anxiety but have a narrow margin of safety in children. General dentists may inappropriately prescribe gabapentin and stimulants. National evidence on dispensing rates of these high-alert medicines by dentists to children is limited.

METHODS

We utilize join-point regression to identify changes in fills for opioids, sedatives, benzodiazepines, gabapentin, and stimulants to children <18 years from 2012 to 2019 in a national dataset comprising 92% of dispensed outpatient prescriptions by dentists.

RESULTS

From 2012 to 2019, 3.8 million children filled prescriptions for high-alert drugs from general dentists. National quarterly dispensing of high-alert drugs decreased 63.1%, from 10456.0 to 3858.8 days per million. Opioids accounted for 69.4% of high-alert prescriptions. From 2012 to 2019, fills for opioids, sedatives, benzodiazepines, and stimulants decreased by 65.2% (7651.8 to 2662.7), 43.4% (810.9 to 458.7), 43.6% (785.7 to 442.7) and 89.3% (825.6 to 88.6 days per million), respectively. Gabapentin increased 8.1% (121.8 to 131.7 days per million). A significant decrease in high-alert fills occurred in 2016, (-6.0% per quarter vs. -1.6% pre-2016, P-value<0.001), especially for opioids (-7.0% vs. -1.2%, P-value<0.001). Older teenagers (15-17 years) received 42.5% of high-alert prescriptions. Low-income counties in the South were overrepresented among top-prescribing areas in 2019.

CONCLUSIONS

We found promising national decreases in fills for high-alert medicines to children by general dentists from 2012 to 2019. However, older teenagers and children in some counties continued to receive dental opioids at high rates. Future efforts should address non-evidence-based pain management in these groups.

Designing audit and feedback dashboards for dentists to monitor their opioid prescribing

BACKGROUND AND OBJECTIVE

Prescription drug abuse is a major factor leading to drug overdose deaths in the US and dentists are one of the leading prescribers of opioid pain medication. Knowing that Audit & Feedback (A&F) dashboards are an effective tool and are used as quality improvement interventions, we aimed to develop such dashboards personalized for dental providers which could allow them to monitor their own opioid prescribing performance.

METHODS

In this paper we report on the process for designing the A&F dashboards for dentists which were developed by using an iterative human-centered design process. The results obtained from each iteration were used to enrich the information needs analyses, provide function testing, and guide the design decisions of the next iteration.

RESULTS

Engaging dentists in the development and refinement of the dashboards while using the think-aloud protocol for user-testing, provided rapid feedback and identified areas that were confusing and needed either a redesign or additional explanatory content. The final version of dashboards consisted of displaying necessary information through easy to interpret visualizations and interactive features. These included providing access to current national and organizational prescribing guidelines, displaying changes in individual prescribing behavior over time, comparing individual prescribing rate to peer group rate and target rate, displaying procedure specific prescribing, integrating patient reported post-operative dental pain experience and providing navigation and interpretation tips for users. The dashboards were easy to learn and understand for the dentists and were deemed as worth using often in dental practice.

CONCLUSION

Our research was able to demonstrate the creation of useful and usable A&F dashboards using data from electronic dental records and patient surveys, for dentists to effectively monitor their opioid prescribing behavior. Efficacy of the dashboards will be tested in future work.

Reducing Opioid Analgesic Prescribing in Dentistry Through Prescribing Defaults: A Cluster-Randomized Controlled Trial

OBJECTIVE

To determine the effect of a uniform, reduced, default dispense quantity for new opioid analgesic prescriptions on the quantity of opioids prescribed in dentistry practices.

METHODS

We conducted a cluster-randomized controlled trial within a health system in the Bronx, NY, USA. We randomly assigned three dentistry sites to a 10-tablet default, a 5-tablet default, or no change (control). The primary outcome was the quantity of opioid analgesics prescribed in the new prescription. Secondary outcomes were opioid analgesic reorders and health service utilization within 30 days after the new prescription. We analyzed outcomes from 6 months before implementation through 18 months after implementation.

RESULTS

Overall, 6,309 patients received a new prescription. Compared with the control site, patients at the 10-tablet-default site had a significantly larger change in prescriptions for 10 tablets or fewer (38.7 percentage points; confidence interval [CI]: 11.5 to 66.0), lower number of tablets prescribed (-3.3 tablets; CI: -5.9 to -0.7), and lower morphine milligram equivalents (MME) prescribed (-14.1 MME; CI: -27.8 to -0.4), which persisted in the 30 days after the new prescription despite a higher percentage of reorders (3.3 percentage points; CI: 0.2 to 6.4). Compared with the control site, patients at the 5-tablet-default site did not have a significant difference in any outcomes except for a significantly higher percentage of reorders (2.6 percentage points; CI: 0.2 to 4.9).

CONCLUSIONS

Our findings further support the efficacy of strategies that lower default dispense quantities, although they indicate that caution is warranted in the selection of the default.

A critical review of cannabis in medicine and dentistry: A look back and the path forward

Introduction

In the last two decades, our understanding of the therapeutic utility and medicinal properties of cannabis has greatly changed. This change has been accompanied by widespread cannabis use in various communities and different age groups, especially within the United States. With this increase, we should consider the potential effects of cannabis–hemp on general public health and how they could alter therapeutic outcomes.

Material and Methods

The present investigation examined cannabis use for recreational and therapeutic use and a review of pertinent indexed literature was performed. The focused question evaluates “how cannabis or hemp products impact health parameters and do they provide potential therapeutic value in dentistry, and how do they interact with conventional medicines (drugs).” Indexed databases (PubMed/Medline, EMBASE) were searched without any time restrictions but language was restricted to English.

Results

The review highlights dental concerns of cannabis usage, the need to understand the endocannabinoid system (ECS), cannabinoid receptor system, its endogenous ligands, pharmacology, metabolism, current oral health, and medical dilemma to ascertain the detrimental or beneficial effects of using cannabis–hemp products. The pharmacological effects of pure cannabidiol (CBD) have been studied extensively while cannabis extracts can vary significantly and lack empirical studies. Several metabolic pathways are affected by cannabis use and could pose a potential drug interaction. The chronic use of cannabis is associated with health issues, but the therapeutic potential is multifold since there is a regulatory role of ECS in many pathologies.

Conclusion

Current shortcomings in understanding the benefits of cannabis or hemp products are limited due to pharmacological and clinical effects not being predictable, while marketed products vary greatly in phytocompounds warrant further empirical investigation. Given the healthcare challenges to manage acute and chronic pain, this review highlights both cannabis and CBD‐hemp extracts to help identify the therapeutic application for patient populations suffering from anxiety, inflammation, and dental pain.

The Opioid Analgesic Reduction Study (OARS)-a comparison of opioid vs. non-opioid combination analgesics for management of post-surgical pain: a double-blind randomized clinical trial

BACKGROUND

Everyday people die unnecessarily from opioid overdose-related addiction. Dentists are among the leading prescribers of opioid analgesics. Opioid-seeking behaviors have been linked to receipt of initial opioid prescriptions following the common dental procedure of third molar extraction. With each opioid prescription, a patient's risk for opioid misuse or abuse increases. With an estimated 56 million tablets of 5 mg hydrocodone annually prescribed after third molar extractions in the USA, 3.5 million young adults may be unnecessarily exposed to opioids by dentists who are inadvertently increasing their patient's risk for addiction.

METHODS

A double-blind, stratified randomized, multi-center clinical trial has been designed to evaluate whether a combination of over-the-counter non-opioid-containing analgesics is not inferior to the most prescribed opioid analgesic. The impacted 3rd molar extraction model is being used due to the predictable severity of the post-operative pain and generalizability of results. Within each site/clinic and gender type (male/female), patients are randomized to receive either OPIOID (hydrocodone/acetaminophen 5/300 mg) or NON-OPIOID (ibuprofen/acetaminophen 400/500 mg). Outcome data include pain levels, adverse events, overall patient satisfaction, ability to sleep, and ability to perform daily functions. To develop clinical guidelines and a clinical decision-making tool, pain management, extraction difficulty, and the number of tablets taken are being collected, enabling an experimental decision-making tool to be developed.

DISCUSSION

The proposed methods address the shortcomings of other analgesic studies. Although prior studies have tested short-term effects of single doses of pain medications, patients and their dentists are interested in managing pain for the entire post-operative period, not just the first 12 h. After surgery, patients expect to be able to perform normal daily functions without feeling nauseous or dizzy and they desire a restful sleep at night. Parents of young people are concerned with the risks of opioid use and misuse, related either to treatments received or to subsequent use of leftover pills. Upon successful completion of this clinical trial, dentists, patients, and their families will be better able to make informed decisions regarding post-operative pain management.

Opioid-Prescribing Patterns in Connecticut and New Jersey Following Third Molar Extractions

OBJECTIVE

In recent years, opioid misuse has resulted in much scrutiny on providers' prescribing habits. The purpose of this study was to analyze prescribing habits in the context of third molar extractions as a model for promoting better postsurgical pain management.

METHODS

This was a cross-sectional survey of oral maxillofacial surgeons in Connecticut and New Jersey. A total of 291 practitioners were contacted to complete an online survey using Qualtrics Research Services to determine prescribing habits following third molar extractions.

RESULTS

The most common approach for postoperative analgesia was nonsteroidal anti-inflammatory drugs (NSAIDs) and an opioid/acetaminophen (APAP) combination as 2 separate prescriptions, reported by 36% of participants. The combination of hydrocodone/APAP was the most common opioid formulation, and an average of 10.93 ± 4.51 opioid pills were prescribed with a maximum of 20 pills reported. Most providers (79%) consistently provided patients with opioid information. Only 22% reported always checking opioid-monitoring programs; however, providers were more likely to check if prescribing more than ∼11 opioid pills (P = .0228). Most reported using dexamethasone (82%) and bupivacaine (56%) intraoperatively, while ketorolac was less common (15%). No association was found between the quantity of opioids prescribed and the use of intraoperative ketorolac, steroids, or bupivacaine (P > .05).

CONCLUSION

There remains to be a universal standard for using opioids for postoperative pain management in dentistry. Providers should be mindful when prescribing opioids and consider using NSAIDs and APAP for baseline pain plus a separate opioid prescription for breakthrough pain. Additional focus on minimizing the quantity of opioids prescribed and self-reflecting on prescribing and practice habits to further reduce opioid-related complications is warranted.

Plan Type and Opioid Prescriptions for Children in Medicaid

BACKGROUND

Opioids are generally an inappropriate acute pain management strategy in children, particularly because of the risk for diversion and subsequent misuse and abuse.

OBJECTIVES

To examine associations between Medicaid plan type [coordinated care organization (CCO), managed care (MC), fee-for-service (FFS)] and whether a child received an opioid prescription.

RESEARCH DESIGN

Secondary analysis of Oregon Medicaid data (January 1, 2016 to December 31, 2017).

SUBJECTS

Medicaid-enrolled children ages 0-17 (N=200,169).

MEASURES

There were 2 outcomes: whether a child received an opioid prescription from (a) any health provider or (b) from a visit to the dentist. Predictor variables included Medicaid plan type, age, sex, race, and ethnicity.

RESULTS

About 6.7% of children received an opioid from any health provider and 1.2% received an opioid from a dentist visit. Children in a CCO were significantly more likely than children in a MC (P<0.01) or FFS (P=0.02) plan to receive an opioid from any health provider. Children in a CCO were also significantly more likely than children in MC or FFS to receive an opioid from a dentist visit (P<0.01).

CONCLUSIONS

Pediatric opioid prescriptions vary by plan type. Future efforts should identify reasons why Medicaid-enrolled children in a CCO plan are more likely to be prescribed opioids.

Variations in Schedule III prescription patterns in a Medicaid population pre- and post-policy

The present study investigated variations in patient movement patterns between prescribers before and after House Bill 1 (HB1) implementation in Kentucky using network abstractions (PPN: prescriber-prescriber networks) from a one-month cross-sectional Schedule III prescription data in a Medicaid population. Network characteristics such as degree centrality distribution of PPN was positively skewed and revealed Dental Practitioners to be the highly connected specialty with opioid analgesic hydrocodone-acetaminophen to be the most commonly prescribed drug. Taxonomy enrichment of the prescriber specialties in PPN using chi-square test revealed a reduction in the enriched taxonomies Post-HB1 compared to Pre-HB1 with Dental practitioners being constitutively enriched (p < 0.05). PPNs were also found to exhibit rich community structure revealing inherent clustering of prescribers as a result of patient movement, and were markedly different from those generated by random graph models. The magnitude of deviation from random graphs decreased Post-HB1 relative to Pre-HB1. The proposed network approach provides system-level insights into prescribers with potential to complement classical reductionist approaches and aggregate statistical measures used in assessing changes in prescription patterns pre- and post- policy implementation. It can provide preliminary cues into drug seeking behavior, and facilitate targeted surveillance of prescriber communities.

U.S. Military Veteran Versus Nonveteran Use of Licit and Illicit Substances

INTRODUCTION

To provide up-to-date substance use surveillance data among U.S. military veterans versus nonveterans, this study assesses current use of tobacco products, alcohol, marijuana, prescription pain relievers, tranquilizers, sedatives, stimulants, cocaine, heroin, methamphetamines, inhalants, and hallucinogens.

METHODS

Pooled data were from the 2015-2017 National Survey on Drug Use and Health, a nationally representative, self-reported survey of the U.S. adult non-institutionalized population. Military veterans were those who had "ever been in the United States Armed Forces" and were "now separated/retired from reserves/active duty" (n=7,301). Nonveterans were those who had never been in the U.S. Armed forces (n=121,366). Age- and gender-stratified weighted prevalence estimates were calculated and compared with chi-square tests. All analyses were conducted in 2019.

RESULTS

Illicit substance use, including marijuana and cocaine, was generally lower among veterans than nonveterans, whereas use of licit substances such as tobacco and alcohol was higher among veterans than nonveterans. The most commonly used substances among veterans were tobacco and alcohol. Among male participants aged 18-25 years, 59.8% of veterans reported past-12-month cigarette/cigar smoking (vs 46.6% of nonveterans), whereas 17.6% reported heavy drinking (vs 12.2% of nonveterans). For both cigarette/cigar smoking and binge drinking, there was a marked narrowing of the male-female gap in prevalence with increasing age among veterans. Female veterans aged 18-25 years reported significantly higher opioid use than their nonveteran counterparts (54.7% vs 35.0%); they also had the highest prevalence of opioid misuse (15.3%) than any other group.

CONCLUSIONS

Intensified efforts are needed to reduce substance use among veterans and provide cessation and mental health services.

Potentially Inappropriate Medication Combination with Opioids among Older Dental Patients: A Retrospective Review of Insurance Claims Data

BACKGROUND

Opioid prescribing by dentists for older patients receiving medications with potential contraindications and the subsequent impact on acute care outcomes is not well described.

OBJECTIVES

Our objective of this paper was to evaluate the use of potentially inappropriate medication combinations (PIMCs) involving opioids prescribed by dentists according to the Beers Criteria and risks of 30-day emergency department (ED) visits and all-cause hospitalization among commercially insured dental patients ages 65 years and older.

METHODS

We conducted a retrospective cohort study of 40,800 older dental patient visits in which opioids were prescribed between 2011 and 2015 using the IBM MarketScan databases. Data collection from dental, medical, and pharmacy claims included information on the concurrent use of PIMCs and outcomes of all-cause acute care utilization over the 30-day period after dental encounters.

RESULTS

For the overall cohort, the median age was 69 years, and 45% were women. The prevalence of PIMCs per Beers Criteria was 10.4%. A total of 947 all-cause acute care events were observed in the 30 days post-dental visit. Patients with PIMCs involving opioids prescribed by dentists according to the Beers Criteria had higher rates of acute care use (3.3% vs 2.2%, p<0.001), which were associated with an increased risk of all-cause acute care utilization (adjusted risk ratio [RR] 1.23, 95% confidence interval [CI] 1.02-1.48). A dose-response relationship was seen with increasing oral morphine equivalents prescribed and increased acute care utilization (p<0.001).

CONCLUSION

A significant proportion of older patients receiving opioids at dental visits use psychotropic medications that in combination should be avoided according to the American Geriatric Society Beers Criteria.

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 procedures, analgesic drug, quantity, and refills) were recorded and studied with respect to national guidelines and recent state legislation using the χ² 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.

A randomized pilot program to reduce opioid use following dental surgery and increase safe medication return

Research indicates that increased cumulative exposure (duration of administration and strength of dose) is associated with long-term opioid use. Because dentists represent some of the highest opioid prescribing medical professionals in the US, dental practices offer a critical site for intervention. The current study used a randomized clinical trial design to examine the efficacy of an opioid misuse prevention program (OMPP), presented as a brief intervention immediately prior to dental extraction surgery. The OMPP provided educational counseling about risks and appropriate use of opioid medication, as well as 28 tablets of ibuprofen (200 mg) and 28 tablets of acetaminophen (500 mg) for weaning off opioid medication. This was compared with a Treatment as Usual (TAU) control condition. Participants were individuals presenting for surgery who were eligible for opioid medication (N = 76). Follow up assessment was conducted at 1 week following surgery, with 4 individuals refusing follow up or not prescribed opioid. Intent to treat analysis indicated a non-significant treatment group effect (N = 72, Beta = 0.16, p = .0835), such that the OMPP group self-reported less opioid use (in morphine milligram equivalents, MMEs) than the TAU group (37.94 vs. 47.79, effect size d = 0.42). Sensitivity analysis, excluding individuals with complications following surgery (n = 6) indicated a significant treatment group effect (N = 66, Beta = 0.24, p = .0259), such that the OMPP group self-reported significantly less MMEs than the TAU group (29.74 vs. 43.59, effect size d = 0.56). Results indicate that a 10-minute intervention and provision of non-narcotic pain medications may reduce the amount of self-administered opioid medication following dental surgery.

Provider beliefs on the Barriers and Facilitators to Prescription Monitoring Programs and Mandated Use

Background: Underutilization of Prescription monitoring programs (PMP), especially in states where participation is voluntary could limit their impact against opioid epidemic. Objectives: To (1) examine PMP use among Iowa healthcare providers (HCPs); (2) identify factors prompting and impeding PMP use, and (3) assess beliefs toward mandating PMP use. Methods: A cross-sectional survey of Iowa HCPs was conducted using a 12-item questionnaire. Survey domains include demographics, current PMP utilization, conditions and barriers associated with PMP use, and perspectives on use mandates. Analyses were based on descriptive statistics, proportional odds and poisson regression models. Results: There were 704 usable responses. Almost all respondents were registered with the PMP with dentists having the lowest rate (p < .001). Nurse practitioners consulted the PMP for the largest proportion of prescriptions, while pharmacists and dentists used significantly less (p < .001). Lack of time was the most common reported barrier impeding PMP use. Red flag behaviors and unfamiliarity with patient were the most common conditions prompting PMP review. HCPs estimated their use of the PMP would significantly increase if integrated into their electronic health records (p < .001). Almost half of HCPs held the opinion that PMP use should never be mandated, although inter-provider variation was present with nurse practitioners most amenable to mandates. Discussion: HCPs displayed variation in PMP use. EMR integration appears to be a strategy for increasing PMP use. There was resistance to mandating PMP use for all controlled substances prescribed and dispensed, with some interest in mandates for new patients only or new controlled substance prescriptions only.

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.

Pattern of Opioid Analgesic Prescription for Adults by Dentists in Nova Scotia, Canada

Global consumption of prescription opioid analgesics has increased dramatically in the past 2 decades, outpacing that of illicit drugs in some countries. The increase has been partly ascribed to the widespread availability of prescription opioid analgesics and their subsequent nonmedical use, which may have contributed to the epidemic of opioid abuse, addiction, and overdose-related deaths. International studies report that dentists may be among the leading prescribers of opioid analgesics, thus adding to the societal impact of this epidemic. Between 2009 and 2011, dentists in the United States prescribed 8% to 12% of opioid analgesics dispensed. There is little information on the pattern of opioid analgesic prescription by dentists in Canada. The aim of this study was to examine the pattern of opioid analgesics prescription by dentists in Nova Scotia (NS), Canada. This retrospective observational study used the provincial prescription monitoring program's record of oral opioid analgesics and combinations dispensed to persons 16 y and older at community pharmacies that were prescribed by dentists from January 2011 to December 2015. During the study period, more than 70% of licensed dentists in NS wrote a prescription for dispensed opioid analgesics, comprising about 17% of all opioid analgesic prescribers. However, dentists were responsible for less than 4% of all prescriptions for dispensed opioid analgesics, prescribing less than 0.5% of the total morphine milligram equivalent (MMEq) of opioid analgesics dispensed over the 5 y. There was a significant downward trend in total MMEq of dispensed opioid analgesics prescribed by dentists from about 2.23 million MMEq in 2011 to 1.93 million MMEq in 2015 (r = -0.97; P = 0.006). Opioid prescription is common among dentists, but their contribution to the overall availability of opioid analgesics is low. Furthermore, there has been a downward trend in total dispensed MMEq of opioid analgesics prescribed by dentists. Knowledge Transfer Statement: This study will serve to inform dentists and policy makers on the types and dosage of opioid analgesics being prescribed by dentists. The study may prompt dentists to reflect on and adjust their practice of opioid analgesic prescription in view of the current opioid analgesic epidemic.

Effect of FDA Warning on Codeine and Alternate Opioid Prescribing After Pediatric Dental Procedures in Ohio

Purpose: Evaluate changes in codeine and alternate opioid prescription filling after pediatric dental procedures associated with the FDA's codeine black box warning for tonsillectomy/adenoidectomy. Methods: Patients aged 0-17 years who underwent any tooth extraction or restorative procedure during August 2011-August 2016 were identified in Ohio Medicaid claims. Interrupted time series analyses were used to evaluate the impact of the FDA's warning on the rates of codeine or alternative opioid prescription fills within 14 days postprocedure. Results: In August 2011, codeine and alternative opioid prescription fills rates after a dental procedure were 2.3 percent and 3.3 percent, respectively. These rates decreased monthly by 0.02 and 0.01 percent, respectively during the study period (P<0.0001). The FDA warning was associated with an immediate drop in codeine prescription filling of 0.4 percent (P<0.001), but there was no such association with alternative opioid prescription filling. The codeine decrease was only significant among extractions with/without concurrent restorative procedures involving males, 12- to 17-year-olds, Caucasians, and small metropolitan area residents. Conclusions: Opioid prescription filling after pediatric dental procedures decreased between 2011 and 2016 among Medicaid beneficiaries. In addition, there was a significant immediate reduction in codeine prescription filling after the FDA's codeine black box warning for tonsillectomy/adenoidectomy.

Prescribing Associated with High-Risk Opioid Exposures Among Non-cancer Chronic Users of Opioid Analgesics: a Social Network Analysis

BACKGROUND

The continued rise in fatalities from opioid analgesics despite a steady decline in the number of individual prescriptions directing ≥ 90 morphine milligram equivalents (MME)/day may be explained by patient exposures to redundant prescriptions from multiple prescribers.

OBJECTIVES

We evaluated prescribers' specialty and social network characteristics associated with high-risk opioid exposures resulting from single-prescriber high-daily dose prescriptions or multi-prescriber discoordination.

DESIGN

Retrospective cohort study.

PARTICIPANTS

A cohort of prescribers with opioid analgesic prescription claims for non-cancer chronic opioid users in an Illinois Medicaid managed care program in 2015-2016.

MAIN MEASURES

Per prescriber rates of single-prescriber high-daily-dose prescriptions or multi-prescriber discoordination.

KEY RESULTS

For 2280 beneficiaries, 36,798 opioid prescription claims were submitted by 3532 prescribers. Compared to 3% of prescriptions (involving 6% of prescribers and 7% of beneficiaries) that directed ≥ 90 MME/day, discoordination accounted for a greater share of high-risk exposures-13% of prescriptions (involving 23% of prescribers and 24% of beneficiaries). The following specialties were at highest risk of discoordinated prescribing compared to internal medicine: dental (incident rate ratio (95% confidence interval) 5.9 (4.6, 7.5)), emergency medicine (4.7 (3.8, 5.8)), and surgical subspecialties (4.2 (3.0, 5.8)). Social network analysis identified 2 small interconnected prescriber communities of high-volume pain management specialists, and 3 sparsely connected groups of predominantly low-volume primary care or emergency medicine clinicians. Using multivariate models, we found that the sparsely connected sociometric positions were a risk factor for high-risk exposures.

CONCLUSION

Low-volume prescribers in the social network's periphery were at greater risk of intended or discoordinated prescribing than interconnected high-volume prescribers. Interventions addressing discoordination among low-volume opioid prescribers in non-integrated practices should be a priority. Demands for enhanced functionality and integration of Prescription Drug Monitoring Programs or referrals to specialized multidisciplinary pain management centers are potential policy implications.

Prescription Drug Abuse Among Patients in Rural Dental Practices Reported by Members of the National Dental PBRN

PURPOSE

This study compared rural to nonrural dentists with respect to opioid prescribing practices, perceptions about prescription drug abuse among patients, and training relevant to pain management and addictions.

METHODS

A web-based, cross-sectional questionnaire was administered to practicing dentist members of the National Dental Practice-Based Research Network (PBRN; N = 822) and linked with network enrollment questionnaire data regarding practitioner demographics and practice characteristics. Pain management prescribing practices and perceptions regarding relevance and scope of addiction and drug diversion among patients were assessed. Rural practice was defined as a practice whose ZIP Code has more than 50% of its population in either a nonmetropolitan county and/or a rural Census tract.

FINDINGS

Rural dentists were significantly more likely than their nonrural counterparts to recommend nonsteroidal anti-inflammatory agents/acetaminophen in combination with prescribing an opioid [F (1,820) = 4.59, P = .03]. Compared to nonrural dentists, rural dentists were more likely to report that opioid abuse/diversion was a problem in their practices [χ² [1, n = 807] = 6.85, P < .001], were more likely to have suspected a patient of abuse or diversion [χ² [1, n = 807] = 10.12, P = .001], and were more likely to have refrained from prescribing due to suspicions of abuse or diversion [χ² [1, n = 807] = 12.49, P < .001].

CONCLUSION

Rural dentists may be disproportionately impacted by patients' opioid abuse and represent a viable target for educational outreach that encourages screening, identification, and referral of patients in need of drug abuse treatment.

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

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.

Training experiences regarding pain management, addiction, and drug diversion of dentists enrolled in the National Dental Practice-Based Research Network

Background: The purpose of this study was to describe dentists' training experiences relevant to pain management, addiction, and prescription opioid drug diversion and examine associations between these training experiences and dentists' opioid prescribing practices. Methods: A Web-based, cross-sectional survey was conducted among practicing dentist members of the National Dental Practice-Based Research Network (PBRN; N = 822). The survey assessed pain management prescribing practices and training experiences related to pain management and assessment for addiction and drug diversion. Survey data were linked with National Dental PBRN Enrollment Questionnaire data regarding practitioner demographics and practice characteristics. Results: The majority of dentists (67%) reported prior training in pain management; however, a minority of dentists reported prior training regarding identification and assessment of drug abuse or addiction (48%) or identification of prescription drug diversion (25%). The majority of training experiences across all topics occurred through continuing dental education participation. Dental school training relevant to pain management, addiction, and identification of drug diversion was more prevalent among more recent dental school graduates. Training experiences were associated with prescribing practices. Conclusions: Results suggest that across multiple levels of training, many dentists are not receiving training specific to addiction assessment and identification of drug diversion. Such training is associated with greater consistency of risk mitigation implementation in practice.

Clinical indications associated with opioid initiation for pain management in Ontario, Canada: a population-based cohort study

Concerns over prescription opioids contributing to high levels of opioid use disorder and overdose have led policymakers and clinicians to seek means to reduce inappropriate and high-dose initial prescriptions. To inform such efforts, we sought to describe the clinical indications associated with opioid initiation and the characteristics of the initial prescriptions and patients through a retrospective population-based cohort study. Our cohort included Ontarians initiating prescription opioids for pain management between April 1, 2015, and March 31, 2016. We identified the apparent clinical indication for opioid initiation by linking prescription drug claims to procedural and diagnostic information on health service records on the day of, and 5 days preceding prescription. Outcomes included initial opioid type, prescription duration, and daily dose (in milligram morphine equivalents), stratified either by indication or indication cluster. Among 653,993 individuals, we successfully classified 575,512 (88.0%) people initiating opioids into 23 clinical indications in 6 clusters: dental (23.2%); postsurgical (17.4%); musculoskeletal (12.0%); trauma (11.2%); cancer/palliative care (6.5%); and other less frequent indications (17.7%). Individuals with postsurgical pain received the highest daily doses (40.5% with greater than 50 milligram morphine equivalent), and those with musculoskeletal pain received more initial prescriptions with a duration exceeding 7 days (34.2%). Opioids are initiated for a wide range of indications with varying doses and durations; yet, those who initiated opioids for postsurgical and musculoskeletal pain received the greatest doses and durations of therapy, respectively. These findings may help tailor and prioritize efforts to promote more appropriate opioid prescribing.

Do Oral and Maxillofacial Surgeons Over-Prescribe Opioids After Extraction of Asymptomatic Third Molars?

PURPOSE

Opioid abuse is a public health concern. Oral opioids are prescribed after removal of third molars, but the amount needed for adequate postoperative analgesia is unknown. The purpose of this study was to quantify opioid need after third molar extractions.

MATERIALS AND METHODS

This is a prospective cohort study of consecutive patients who had asymptomatic third molars extracted with intravenous sedation at the Boston Children's Hospital (Boston, MA) from June through October 2018 by 3 attending surgeons. To be included, patients had to have had 4 third molars removed. Patients were excluded if they had a concomitant procedure, preoperative infection, postoperative inflammatory complication, chronic pain condition, or did not complete the study. Postoperative prescriptions and instructions included 1) oxycodone 5-mg tablets with 1 tablet taken every 6 hours as needed (dispensed, 6); 2) ibuprofen 600-mg tablets with 1 tablet taken every 6 hours as needed (dispensed, 20); and 3) acetaminophen 325-mg tablets with 2 tablets taken every 6 hours as needed (dispensed, 40). Participants reported medication use by electronic questionnaire each day for 7 postoperative days (PODs). Descriptive statistics were calculated.

RESULTS

Eighty-one patients (56% female; mean age, 19.4 ± 7.7 yr) were included. The average number of oxycodone tablets used was 0.04 ± 0.24, and the highest daily use of oxycodone was on POD 2 (1.0 ± 0.0 tablet). Oxycodone was taken by 3 patients (4%) on POD 1, 4 (5%) on POD 2, 2 (3%) on PODs 3 and 4, and 0 on PODs 5 to 7. Seventy-five patients (93%) used no postoperative oxycodone; 466 prescribed oxycodone tablets remained unfilled or unused. Ibuprofen 600 mg was used for 4.6 ± 2.2 PODs and acetaminophen 650 mg was used for 3.4 ± 1.9 PODs.

CONCLUSIONS

Oral opioid use after third molar extractions is minimal. Caution is necessary to avoid over-prescribing.

Prescription Drug Monitoring Program Use: National Dental PBRN Results

INTRODUCTION

The American Dental Association recommends that dentists use a prescription drug monitoring program (PDMP) prior to prescribing an opioid for acute pain management.

OBJECTIVE

The objective of this study was to examine dentists' experiences using their state PDMP, as well as the impact that state-mandated registration policies, mandated use policies, and practice characteristics had on the frequency with which dentists used their PDMP.

METHODS

We conducted a web-based cross-sectional survey among practicing dentist members of the National Dental Practice-Based Research Network ( n = 805). The survey assessed prescribing practices for pain management and implementation of risk mitigation strategies, including PDMP use. Survey data were linked with network Enrollment Questionnaire data to include practitioner demographics and practice characteristics.

RESULTS

Nearly half of respondents ( n = 375, 46.6%) reported having never accessed a PDMP, with the most common reasons for nonaccess being lack of awareness ( n = 214, 57.1%) and lack of knowledge regarding registration and use ( n = 94, 25.1%). The majority of PDMP users reported the program to be very helpful (58.1%) or somewhat helpful (31.6%). Dentists reported that PDMP use most often did not change their intended prescribing behavior (40.2%), led them not to prescribe an opioid (33.5%), or led them to prescribe fewer opioid doses (25.5%). Presence of a mandated use policy was significantly associated with increased frequency of PDMP use across a variety of situations, including prior to 1) prescribing any opioid for pain management, 2) issuing refills, 3) prescribing to new patients, and 4) prescribing to patients deemed high risk.

CONCLUSION

Findings suggest that the majority of dentists find PDMPs helpful in informing their opioid-prescribing practices. Whereas the existence of a state-mandated use policy is a consistent predictor of dentists' PDMP use, outreach and education efforts may overcome key barriers to use identified in this study.

KNOWLEDGE TRANSFER STATEMENT

Findings from this national survey suggest that the majority of practicing dentists find PDMPs helpful in informing their opioid-prescribing practices; however, consistent PDMP use was not common. Whereas the existence of a state-mandated use policy is a consistent predictor of dentists' PDMP use, outreach and education efforts may overcome key barriers to use identified in this study.

Opioid abuse/dependence among those hospitalized due to periapical abscess

AIM

Opioid abuse/dependence (OAD) is an emerging public health crisis in the USA. The aim of the present study was to estimate the nationwide prevalence of OAD in those hospitalized due to periapical abscess in the USA.

METHODS

The Nationwide Inpatient Sample for 2012-2014 was used. All patients who were hospitalized due to periapical abscess were selected for analysis. In this cohort, OAD was identified and used as the outcome variable. A mix of patient and geographic factors were used as independent variables. The simultaneous association between outcome and independent variables was examined by a multivariable logistic regression model. Clustering of outcomes within hospitals was adjusted. Odds of OAD were computed for all independent variables.

RESULTS

During the study period, 30 040 patients were hospitalized due to periapical abscess; 1.5% of these had OAD. Those aged 18-29 years (odds ratio [OR] = 3.69, 95% confidence interval [CI] = 1.76-7.72, P < 0.01) and 30-44 years (OR = 3.19, 95% CI = 1.77-5.76, P < 0.01) were associated with higher odds for OAD compared to those aged 45-64 years. Blacks were associated with lower odds for OAD compared to whites (OR = 0.52, 95% CI = 0.28-0.95, P = 0.03). Those covered by Medicare (OR = 4.08, 95% CI = 1.458-11.44, P = 0.01), Medicaid (OR = 5.86, 95% CI = 2.22-15.47, P < 0.01), and those who were uninsured (OR = 3.68, 95% CI = 1.30-10.45, P = 0.01) were associated with higher odds for OAD compared to those covered by private insurance. The odds of OAD increased with comorbid burden (OR = 1.66, 95% CI = 1.50-1.84, P < 0.01).

CONCLUSIONS

High-risk groups that are likely to have OAD were identified among those hospitalized due to periapical abscess.

Opioid prescribing and risk mitigation implementation in the management of acute pain: Results from The National Dental Practice-Based Research Network

BACKGROUND

Minimal information exists regarding the consistency and correlates of dentists' implementation of risk mitigation strategies when prescribing opioids, including risk screening, prescription drug monitoring program (PDMP) use, and patient education.

METHODS

The authors conducted a Web-based, cross-sectional survey among practicing dentist members of The National Dental Practice-Based Research Network. The authors used the survey to assess pain management prescribing practices and risk mitigation implementation. The authors linked survey data with network enrollment questionnaire data to include practitioner demographic and practice characteristics.

RESULTS

A total of 822 dentists completed the survey. A minority of dentists reported prescribing opioids only (11%) or opioids in combination with a recommendation for nonsteroidal anti-inflammatory drugs or acetaminophen (18%) to one-half or more of their patients needing management of acute pain. Higher levels of opioid prescribing were associated significantly with less consistent implementation of PDMP use (r = -0.20) and patient education (r = -0.11).

CONCLUSIONS

Most dentists reported infrequent PDMP use and counseling patients regarding risks, storage, and disposal of opioids. Higher frequency of opioid prescribing was associated with less consistent risk mitigation implementation.

PRACTICAL IMPLICATIONS

When opioid prescribing is indicated, risk of misuse and diversion may be mitigated by consistent PDMP use and provision of patient education. Dental education in this arena is needed.

The economic burden of opioid prescription by dentists: A 12-month survey of consumer expenditure in Brazil

OBJECTIVES

To describe consumer expenditure on opioids prescribed by dentists in Brazil during a 12-month period.

METHODS

We surveyed individual dispensed prescriptions of opioids in private pharmacies from October 2012 to September 2013. A descriptive analysis of costs included a calculation of the overall and mean maximum price to consumers. Monetary costs were converted from local currency units (Brazilian Real - BRL) to international dollars using purchasing power parity (PPP) exchanging rates.

RESULTS

129,708 prescriptions were retrieved from the database. The overall expenditure on opioids was R$4,316,383.46 BRL or $2,721,315.82 (PPP). The mean cost of an individual prescription was R$33.27 BRL ($20.98 PPP), ranging from 14.19 to 3,255.60 BRL. Codeine was frequently prescribed (87.2 percent).

CONCLUSIONS

The expenditure on opioids is a significant cost to Brazilian patients, especially given that the Brazilian Public Health System should dispense these drugs free of charge. Codeine was the most prescribed opioid.

Preoperative Preparation and Planning of the Oral and Maxillofacial Surgery Patient

Every patient is different and has the potential to respond unfavorably to anesthetic and surgical intervention. Preparation is the key to optimizing patient outcome.

Unused opioid analgesics and drug disposal following outpatient dental surgery: A randomized controlled trial

BACKGROUND

Individuals who abuse prescription opioids often use leftover pills that were prescribed for friends or family members. Dental surgery has been identified as a common source of opioid prescriptions. We measured rates of used and unused opioids after dental surgery for a pilot program to promote safe drug disposal.

METHODS

We conducted a randomized controlled trial of opioid use patterns among patients undergoing surgical tooth extraction at a university-affiliated oral surgery practice. The primary objective was to describe opioid prescribing and consumption patterns, with the number of unused opioid pills remaining on postoperative day 21 serving as the primary outcome. The secondary aim was to measure the effect of a behavioral intervention (informing patients of a pharmacy-based opioid disposal program) on the proportion of patients who disposed or reported intent to dispose of unused opioids. (NCT02814305) Results: We enrolled 79 patients, of whom 72 filled opioid prescriptions. On average, patients received 28 opioid pills and had 15 pills (54%) left over, for a total of 1010 unused pills among the cohort. The behavioral intervention was associated with a 22% absolute increase in the proportion of patients who disposed or reported intent to dispose of unused opioids (Fisher's exact p=0.11).

CONCLUSION

Fifty-four percent of opioids prescribed in this pilot study were not used. The pharmacy-based drug disposal intervention showed a robust effect size but did not achieve statistical significance. Dentists and oral surgeons could potentially reduce opioid diversion by moderately reducing the quantity of opioid analgesics prescribed after surgery.
