Prescribing patterns of analgesics and other medicines by dental practitioners in Australia from 2001 to 2012

Opioid Analgesic Prescribing Practice in a Predoctoral Dental School Over a Decade

BACKGROUND

Dental schools play an influential role in shaping education and training of future dental professionals. This study investigated the prevalence and evolving trend of opioid analgesic prescription across dental surgical and endodontic procedures between 2013-2023 within a predoctoral dental school.

METHODS

Electronic health records (axiUm database) of our predoctoral dental school were retrospectively searched for dental surgical and endodontic procedure codes dated between July 2013-May 2023. Differences in frequency of opioid prescriptions across study period and procedure types were compared using Chi-square tests. Logistic regression was used to determine whether COVID-19 pandemic, tooth involved, patient's age, or multiple-procedure were associated with the prescription of opioid analgesics.

RESULTS

A total of 1,145 opioid prescriptions were dispensed after 54,652 dental surgical and endodontic procedures completed over 41,343 dental visits. The prevalence of opioid-prescribing practice was 3.3% after dental surgical procedures and 0.7% after endodontic procedures, with a statistically significant difference across procedure types (p < 0.00001). 42.4% of all opioid prescriptions were dispensed after surgical removal of erupted teeth. Opioid-analgesic prescribing practice was influenced by multiple procedures conducted during the same dental visit (odds ratio, OR = 9,047,709), tooth number (OR = 1.04), and COVID-19 period (OR = 6,101,435). The 10-year period revealed a -58.3% percentage change in opioid-prescribing practices (from 1.2% in 2013 to 0.5% in 2023), after a peak in 2016 (∼6.1%).

CONCLUSIONS

There was a low combined 2.8% prevalence of opioid-analgesic prescriptions following dental surgical (3.3% prevalence) and endodontic (0.7% prevalence) procedures at a predoctoral dental school, with a steady decline after 2016.

Antibiotic prescribing patterns among dentists in Italy and Albania: A comparative questionnaire analysis

Objective

To investigate the therapeutic and prophylactic use of antibiotics in dentistry in two countries.

Methods

This study used questionnaires to examine the prescribing habits of dentists in Italy (9th country in Europe for systemic antibiotic administration) and Albania an Extra European Union Country. A total of 1300 questionnaires were sent to Italian and Albanian dentists.

Results

In total, 180 Italian and 180 Albanian dentists completed the questionnaire. Penicillin use was higher in Italy (96.6 %) than Albania (82.8 %). Only 26.1 % of Italian dentists and 32 % of Albanian dentists followed the national guidelines for antibiotic administration.

Conclusions

Dentists tend to overprescribe antibiotics for treating existing conditions or as prophylaxis. They also highlighted a lack of adherence to established guidelines for antibiotic use. In addition, factors such as age, nationality, and sex appeared to influence the choice of antibiotics.

Clinical significance

Recently, the growth of antibiotic-resistant bacteria has become a global concern. The authors of this article highlight how dentists often prescribe antibiotics without a real need. Limiting the use of antibiotics in this category may help mitigate antibiotic resistance.

Alternatives to dental opioid prescribing after tooth extraction (ADOPT): protocol for a stepped wedge cluster randomized trial

BACKGROUND

Dentists and oral surgeons are leading prescribers of opioids to adolescents and young adults (AYA), who are at high risk for developing problematic opioid use after an initial exposure. Most opioids are prescribed after tooth extraction, but non-opioid analgesics provide similar analgesia and are recommended by multiple professional organizations.

METHODS

This multi-site stepped wedge cluster-randomized trial will assess whether a multicomponent behavioral intervention can influence opioid prescribing behavior among dentists and oral surgeons compared to usual practice. Across up to 12 clinical practices (clusters), up to 33 dentists/oral surgeons (provider participants) who perform tooth extractions for individuals 12-25 years old will be enrolled. After enrollment, all provider participants will receive the intervention at a time based on the sequence to which their cluster is randomized. The intervention consists of prescriber education via academic detailing plus provision of standardized patient post-extraction instructions and blister packs of acetaminophen and ibuprofen. Provider participants will dispense the blister packs and distribute the patient instructions at their discretion to AYA undergoing tooth extraction, with or without additional analgesics. The primary outcome is a binary, patient-level indicator of electronic post-extraction opioid prescription. Data for the primary outcome will be collected from the provider participant's electronic health records quarterly throughout the study. Provider participants will complete a survey before and approximately 3 months after transitioning into the intervention condition to assess implementation outcomes. AYA patients undergoing tooth extraction will be offered a survey to assess pain control and satisfaction with pain management in the week after their extraction. Primary analyses will use generalized estimating equations to compare the binary patient-level indicator of being prescribed a post-extraction opioid in the intervention condition compared to usual practice. Secondary analyses will assess provider participants' perceptions of feasibility and appropriateness of the intervention, and patient-reported pain control and satisfaction with pain management. Analyses will adjust for patient-level factors (e.g., sex, number of teeth extracted, etc.).

DISCUSSION

This real-world study will address an important need, providing information on the effectiveness of a multicomponent intervention at modifying dental prescribing behavior and reducing opioid prescriptions to AYA.

High prevalence of potential psychotropic drugs interactions among Brazilian dental patients

OBJECTIVE

To determine the prevalence of potential drug-drug interactions involving psychotropics prescribed by dentists, and dispensed by the public healthcare system, as well as to describe the severity and level of evidence of those interactions in the state of Minas Gerais, Brazil.

MATERIALS AND METHODS

We conducted data analysis from pharmaceutical claims in which dental patients received systemic psychotropics in 2017. Data from the Pharmaceutical Management System provided the drug dispensing history of the patients, allowing the identification of those on concomitant medication use. The outcome was the occurrence of potential drug-drug interactions, which were detected according to IBM Micromedex®. Independent variables were the patient's sex, age, and the number of drugs used. Descriptive statistics was performed using SPSS v. 26.

RESULTS

Overall, 1480 individuals were prescribed psychotropic drugs. The prevalence of potential drug-drug interactions was 24.8% (n = 366). The total of 648 interactions was observed and, most of which were of major severity (n = 438, 67.6%). Most interactions occurred in female individuals (n = 235; 64.2%), with 46.0 (±17.3) years-old, concurrently taking 3.7 (±1.9) drugs.

CONCLUSION

A substantial proportion of dental patients presented potential drug-drug interactions, mostly of major severity, which might be life-threatening.

Dentists' attitudes and prescription practices for analgesics and antibiotics in Kirkuk Governorate, Iraq

The inappropriate use of analgesics and antibiotics is a widespread issue among dentists globally, leading to the risk of over-prescription that could negatively affect patient health and quality of life. This study aimed to assess the prescribing patterns of analgesics and antibiotics by dentists in Kirkuk City, Iraq, focusing on their attitudes, knowledge levels, and practices regarding these medications. A cross-sectional survey was conducted among 280 dentists in Kirkuk City. The dentists were contacted via their work email addresses, and they responded to a survey. Descriptive statistics, including frequency analysis, were employed to evaluate the appropriateness of analgesic and antibiotic prescriptions for different dental conditions. The first-choice analgesic for 44.6% of dentists was mefenamic acid, followed by paracetamol (31.1%). Regarding antibiotic use, 56.8% of dentists in Kirkuk City reported using antibiotics for empirical and direct therapy. Other dentists (43.2%) revealed that they did not have enough information regarding antibiotic group preference in empirical therapy. 106 of the participants (37.85%) recommended the use of broad-spectrum antibiotics in the treatment of bacterial infections. However, most (45%) were unfamiliar with the group preferences in empirical therapy. Dentists in Kirkuk City showed variations in knowledge and awareness regarding using analgesics and antibiotics. This requires further education and training on proper analgesics and antibiotic stewardship guidelines.

Dental Pain Medication Prescriptions in Minas Gerais, Brazil (2011-2021): A Time-Series Analysis

To describe trends of dentist-prescribed non-steroidal anti-inflammatory drugs (NSAIDs) and analgesics, from January 2011 to December 2021, as well as to examine the relationship between these trends and characteristics of public oral health services in Minas Gerais, Brazil. In this time-series analysis, all drugs were classified according to the Anatomical Therapeutic Chemical classification system. Drugs categorized as NSAIDs (M01A), and other analgesics and antipyretics (N02B) were included for analysis. The outcome was the number of Defined Daily Doses (DDDs)/1000 inhabitants/year for NSAIDs and analgesics in each town. Covariates referred to characteristics of public oral health services, such as coverage, estimates of dental procedures, and frequency of toothache. Linear time-series regression models were used to determine the influence of covariates on the outcome. Overall, there were 58,482 prescriptions of NSAIDs recorded in thirty-eight towns, while 47,499 prescriptions of analgesics in forty-three towns. For each year, there was a 0.38 (p < 0.001), and 0.28 (p < 0.001) increase in the average log of DDD/1000 inhabitants/year for NSAIDs and analgesics, respectively. A positive association was detected between toothache (p < 0.001) and the prescription of NSAIDs. Over the eleven years, there was a general rising trend in the prescriptions. Toothache was the only characteristic of public oral health services associated with the prescription rates of NSAIDs, implying that as the frequency of toothaches increase, so do the prescriptions of NSAIDs in the studied towns.

Prescription patterns of analgesics for oral conditions in india - Analysis of large medical audit data of outpatients in India's private healthcare sector

Background

Analgesic use needs to be regulated due to its adverse effects. This study aimed to analyse the change in prescription rates and patterns of the analgesics prescribed for various oral conditions and to analyse their trends across different age groups and gender to promote rational prescription of drugs and eventually influence regulatory policies.

Methods

Secondary analysis was conducted on medical audit data collected from the private health sector in India. The prescription rate per 1000 persons per year was calculated from May 2013 to April 2016 using the mean projected population (PP) of India. Cross-tabulations were conducted to analyse the prescription rate and their changes across different age groups, gender and oral conditions.

Findings

The mean analgesic prescription rate was highest among the 20-40 age group, and the highest increase was noted in 'non-steroidal anti-inflammatory drug (NSAID) combinations' (3.56 per 1000 persons per year) from May 2013 to April 2016. The 'NSAID combinations' group was also the most prescribed medication across all the oral conditions, with 'diseases of hard tissues' having the highest prescription rate (41.4 and 45.6 per 1000 persons per year, respectively, for 2013-14 and 2015-16).

Interpretation

The results indicate an overall increase in the analgesic prescription rate, especially 'NSAID combinations' for each dental disease and age group, a finding that is hard to explain. Due to the lack of prescription guidelines in India, it is difficult to assess whether these analgesics were prescribed rationally or not.

Association of sociodemographic factors with the prescription pattern of opioids for dental patients: a systematic review

Aim To evaluate the association of patients' sociodemographic factors (sex, age, ethnicity, income, educational level, living environment and health insurance) with the prescription pattern of opioids provided by oral health practitioners.Methods Observational studies that evaluated the association of patients' sociodemographic factors and the likelihood of receiving an opioid prescription provided by an oral health practitioner were eligible. Electronic searches were conducted in Medline (PubMed), Embase, Scopus, Web of Science, LILACS, SciELO, Google Scholar, and OpenGrey up to March 2021. Two authors independently screened the studies, performed data extraction, and assessed the risk-of-bias using the critical appraisal tools developed by the Joanna Briggs Institute (JBI). Certainty of the evidence was assessed with the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE).Results Eight studies were included in this systematic review. Publication year ranged from 2011 to 2021. Narrative synthesis showed with very low certainty of evidence that younger individuals were more likely to receive a prescription of opioids than older individuals. Regarding the other sociodemographic factors and the prescriptions of opioids in dentistry, the evidence is controversial. Risk of bias was low for most items assessed in the included studies.Conclusion The available evidence suggests that there is an association between patients' sociodemographic factors and the prescription patterns of opioids provided by oral health practitioners.

Factors influencing opioid prescribing after tooth extraction

BACKGROUND

Tooth extractions account for most opioid prescriptions from dentists, but specific characteristics that influence likelihood are less established. Improving understanding can facilitate development of tailored interventions to reduce unnecessary opioid prescribing.

METHODS

The authors performed a retrospective review of patients 12 years and older undergoing tooth extraction at the College of Dentistry at the University of Kentucky from 2013 through 2020. The primary end point was issuance of an opioid prescription related to the encounter.

RESULTS

In 44,387 eligible records analyzed, 10,628 (23.9%) patients received an opioid prescription. Results of multivariable logistic regression found that the factors associated with an opioid prescription included receipt of a nonopioid analgesic prescription (adjusted odds ratio [aOR], 11.36; 95% CI, 10.37 to 12.44), receipt of an antibiotic prescription (aOR, 8.29; 95% CI, 7.57 to 9.08), procedural sedation (aOR, 2.11; 95% CI, 1.93 to 2.31), surgical extraction (aOR, 1.96; 95% CI, 1.84 to 2.10), and third molar extractions (1 tooth: aOR, 1.14; 95% CI 1.04 to 1.25; 2 teeth: aOR, 2.09; 95% CI, 2.87 to 2.34; 3 teeth: aOR, 2.73; 95% CI, 2.36 to 3.15; 4 teeth: aOR, 3.45; 95% CI, 3.10 to 3.83). Factors that decreased risk included having an appointment in 2018 or later (aOR, 0.31; 95% CI, 0.29 to 0.33), in a student (aOR, 0.57; 95% CI, 0.51 to 0.65) or resident (aOR, 0.33; 95% CI, 0.31 to 0.36) clinic, and on any day other than Friday (Monday: aOR, 0.83; 95% CI, 0.76 to 0.91; Tuesday: aOR, 0.90; 95% CI, 0.83 to 0.99; Wednesday: aOR, 0.89; 95% CI, 0.81 to 0.97; Thursday: aOR, 0.88; 95% CI 0.81 to 0.97).

CONCLUSIONS

Opioid prescriptions after tooth extraction were common in patients undergoing more extensive procedures. Provider perceptions, habits, and several clinical factors appeared to influence prescribing patterns.

PRACTICAL IMPLICATIONS

The decision to prescribe an opioid appears to be associated with habits and factors perceived to modulate postoperative pain, which may serve as targets for opioid reduction strategies.

Medication Prescribing Practices in Croatian Dental Offices and Their Contribution to National Consumption

Objectives

The objective of this study was to analyse the pattern of medication prescribing among dental practitioners in the Republic of Croatia and to compare it with general medical practice patterns at the national level.

Methods

Data on drug prescriptions were obtained from the Croatian Health Insurance Fund. The number of dentist prescriptions, the cost of medicine denominated in the national currency (Croatian Kuna [HRK]), and the number of packages and days prescribed have been included in the analysis.

Results

Results indicate that there was an increase in medication prescribing(+5.7%) by dentists, with antimicrobials comprising the majority, whereas national medical antimicrobial prescribing had slightly decreased. Antibiotics accounted for 80% of all dentists’ prescriptions, with penicillins being the most commonly prescribed. In particular, amoxicillin with clavulanic acid accounted for 56.4% of all antibiotics prescribed. Such broad-spectrum antibiotics were prescribed more frequently than those of narrow-spectrum. Antibiotics were followed by nonsteroidal anti-inflammatory drugs, with prescribing frequency for ibuprofen increasing by 75%.

Conclusion

Current trends show an increase in the overall prescription rate for all medications prescribed by dentists. The largest increase was observed for the broad-spectrum amoxicillin with clavulanic acid, and ibuprofen. As the apparent widespread use of broad-spectrum antibiotics by dentists in Croatia is in contrast to national and international recommendations for antibiotic stewardship, there is a need for further prospective investigation and possible provider education and guidelines.

Analgesic and Antibiotic Prescription Pattern among Dentists in Guangzhou: A Cross-Sectional Study

Aim

To assess the rational use of drugs and the pattern of prescribing of analgesics and antibiotics for dental management and the information given by dentists in Guangzhou to their patients about the use of these drugs.

Methods

A questionnaire was distributed to 225 dentists working in Guangzhou. The questionnaires consisted of open-ended questions and were given to dentists about analgesic and antibiotic use in dentistry. The questionnaires were analyzed, and absolute frequencies were expressed in the answers to each question. The cases, the analgesics, and the antibiotics recommended by the dentists for each case were determined by the frequency analysis method of descriptive statistics.

Results

Responses to the questionnaire were received from 164 (72.9%) dentists. Paracetamol and diclofenac were the most widely prescribed analgesics. It is also estimated that selective COX-2 inhibitors or opioid analgesics have not been administered by dentists. The antibiotics primarily used for treatment were amoxicillin and metronidazole, and amoxicillin was used for prophylaxis. While more than 80% of dentists indicated that they provided their patients with information on the use of antibiotics, the quality of the information was limited. Patients were primarily instructed by dentists to observe the dosage and dose intervals of the prescription drugs.

Conclusions

The results of the present study demonstrated that dentists most commonly prescribe paracetamol and diclofenac as analgesics, amoxicillin, and metronidazole for the therapy of periodontal, endodontic, and surgical procedures. The results also showed that dentists informed their patients inadequately about analgesic and antibiotic use.

Prescriptions of analgesics and anti-inflammatory drugs in municipalities from a Brazilian Southeast state

The objective of this study was to describe dental prescriptions of non-steroidal anti-inflammatory drugs (NSAID), opioids, and analgesics dispensed by the Brazilian National Health System (BNHS, SUS in Portuguese) of a Southeastern state from January to December 2017, and to analyze their association with socioeconomic and oral health care services' characteristics at municipal level. Data were collected from the Brazilian Integrated Pharmaceutical Care Management System. Medicines were grouped according to the Anatomical Therapeutic Chemical Classification System. The total number of Defined Daily Doses (DDD) and DDD per 1,000 inhabitants (inhab.) per year were presented and compared between groups of municipalities. Data analysis used the Classification and Regression Tree model performed with IBM SPSS 25.0. The total number of NSAID, opioids, and analgesics prescriptions was 70,747 and accounted for 354,221.13 DDD. The most frequently prescribed medicine was ibuprofen (n = 24,676; 34.88%). The number of dental practitioners in the BNHS per 1,000 inhab. (p < 0.001), first dental appointment coverage (p = 0.010), oral health teams per 1,000 inhab. (p=0.022), and the proportion of rural population (p = 0.014) were variables positively associated with the number of DDD of NSAID per 1,000 inhab. per year. Bolsa Família program coverage per 1,000 inhab. (p = 0.022) was negatively associated with NSAID prescription. Regarding analgesics, first dental appointment coverage (p=0.002) and Bolsa Família program coverage per 1,000 inhab. (p = 0.012) were positively associated with DDD per 1,000 inhab. per year. In conclusion, dental prescriptions of analgesics and NSAID in the BNHS were associated with socioeconomic and oral health care services' characteristics.

Financial contributions made by patients towards dispensed medicines prescribed by Australian dentists from 2006 to 2018: a cost-analysis study

Objective This cost-analysis study explored Pharmaceutical Benefits Scheme (PBS) data to determine the financial patient contribution (PC) towards dispensed medications prescribed by dentists and temporal trends in cost contributions. Methods For this study we used the PBS online dataset and only included concessional data in the analysis. Data on dental medications dispensed under the PBS from 2006 to 2018 were accessed. For all medicines aggregated to different pharmacological categories (antibiotics, analgesics and opiates, anti-inflammatories, antifungals, benzodiazepines, anticonvulsants and anti-emetics, and emergency medications), a temporal trend was generated using annual PC data. Cumulative patient and mean annual PC data were also generated in a similar manner. Results Cumulative PC over the study period for dental PBS prescriptions was A$28783361 (A$5.55 per dispensing). The mean annual PC for dental PBS was A$2214105 (for the entire concessional population from 2006 to 2018), with a statistically significant and strong correlation between year and PC (Dental PBS, A$59756 per year; r=0.98: P<0.0001). Antibiotics represented the highest proportion of PC (87.8%), whereas the lowest proportion of PC was for emergency medications (e.g. adrenaline, atropine, glucagon, naloxone), which amounted to 0.003%. Conclusions This study highlights the increasing contributions made by patients towards antibiotic prescriptions. What is known about the topic? Australian dentists can independently prescribe subsidised medications as per a set scope for general and specialist dentists, regulated under the PBS with requisite adherence to specific legal requirements. What does this paper add? This is the first study highlighting the increased level of patient financial contributions towards dental medicines, according to different pharmacological categories, dispensed by pharmacists in Australia. What are the implications for practitioners? This study creates a base for future research assessing the appropriateness of the PBS subsidy and the PBS Safety Net threshold, possibly reassessing the out-of-pocket pricing on brand substitution and appropriately reassessing the current dental PBS schedule.

Dispensing patterns of medicines prescribed by Australian dentists from 2006 to 2018 - a pharmacoepidemiological study

OBJECTIVES

Dentists are independent prescribers that can prescribe subsidised medicines under the Australian Pharmaceutical Benefits Scheme (PBS). It is hypothesised that increased dental prescribing can partly be accounted for by the growth in both the Australian population and the number of practising dentists. This pharmacoepidemiological study aims to determine the dispensing patterns of medications amongst dentists and to identify trends over time.

MATERIALS AND METHODS

Data on dental medications under PBS from 2006 to 2018 were accessed. All the dentist-prescribed concessional medicines dispensed at pharmacies in 2018 were included for time trend analysis. Cumulative dispensing counts and defined daily dose (DDD) per 1,000 concessional population days (DPD) were analysed for time trend analysis.

RESULTS

Out of the 56 medications within the dental PBS schedule, the top 20 medicines had a total cumulative dispensing count of 5,058,556, which accounts for 97.4% of the total dispensing count. Eleven out of 20 medicines were antibiotics. Overall, increases were observed for seven out of 20 medicines (amoxicillin + clavulanic acid, clindamycin, ibuprofen, diazepam, oxycodone, tramadol, naproxen) in both dispensing count and trend, as expressed per DPD.

CONCLUSION

This study highlights the increasing dispensing pattern and trends of dentist-prescribed antibiotics, opioids and benzodiazepines. Further investigation may be required to determine whether the medicine use is appropriate. In the future, this could provide new educational opportunities on the appropriate use of medicines for dentists.

Duration of opioid use and association with socioeconomic status, daily dose and formulation: a two-decade population study in Queensland, Australia

Background There is an association between the duration of prescription opioids use and an increased risk of serious harm, often unintentional. Objective (1) Describe the trends in duration of prescription opioids dispensing and, (2) determine the risk of long-term use (≥4 months) based on patients' socioeconomic status, daily dose in oral daily morphine milligram equivalent, and opioid formulation. Setting Residents of Queensland (2,827,727), Australia from the age 18 years and who were dispensed pharmaceutical opioids from 1 January 1997 to 31 December 2018. Method Retrospective, longitudinal population-based analysis using data obtained from the Monitoring of Drugs of Dependence system of the Monitored Medicines Unit of Queensland Health. Main outcome measure Contribution of socioeconomic status, and daily dose and opioid formulation (modified-release or immediate-release) to the risk of long-term opioid use. Results There was little difference between the number of patients dispensed opioids for ≥4 months and ≤3 months between 1997 and 2011. Thereafter, the number for those using opioids long-term increased. The highest risk of having opioids dispensed for ≥4 months were for patients in the lowest level of socioeconomic status (adjusted odds ratio 1.36; 95% CI, 1.34, 1.38), compared to people in the highest socioeconomic status areas, followed by the low-socioeconomic status areas, mid-socioeconomic status areas, and high-socioeconomic status areas respectively. The risk of being dispensed prescription opioids for ≥4 months significantly increased as the dose increased: adjusted odds ratio 1.73; 95% CI, 1.71, 1.75, adjusted odds ratio 1.89; 95% CI, 1.87, 1.92, and adjusted odds ratio 3.63; 95% CI, 3.58, 3.69 for the ≥20 to <50 oral daily morphine milligram equivalent, ≥50 to <100 oral daily morphine milligram equivalent and ≥100 oral daily morphine milligram equivalent dose categories, respectively. Conclusion Higher doses and living in a low socioeconomic status areas were associated with increased risk of long-term dispensing of opioid prescriptions.

Rapid Progress toward Elimination of Strongyloidiasis in North Queensland, Tropical Australia, 2000-2018

Infection with Strongyloides stercoralis can cause life-threatening disease in immunocompromised patients. Strongyloidiasis is thought to be hyper-endemic in tropical Australia, but there are limited contemporary seroprevalence data to inform local elimination strategies. To define the temporospatial epidemiology of strongyloidiasis in Far North Queensland, tropical Australia, the serology results of 2,429 individuals tested for the infection between 2000 and 2018 were examined. The proportion of positive tests fell from 36/69 (52.2%) in 2000 to 18/222 (8.1%) in 2018 (P < 0.001). Indigenous patients were more likely to have a positive result (Odds Ratio [OR]: 3.9, 95% CI: 3.0-5.0); however, by the end of the study period, residence in a rural or remote location (OR 3.9 (95% CI: 1.2-13.0), P = 0.03) was a more important risk factor for seropositivity than Indigenous status (OR 1.1 (95% CI: 0.4-3.1) P = 0.91). Ivermectin prescription data were available for the period 2004-2018, with annual prescriptions increasing from 100 to 185 boxes (P = 0.01). The volume of ivermectin dispensed correlated negatively with seropositivity (Spearman's rho = -0.62, P = 0.02). An expanded environmental health program was implemented during the study period and likely contributed to the declining seroprevalence; however, the relative contributions of the individual components of this program are difficult to quantify. The seroprevalence of strongyloidiasis has declined markedly in this region of tropical Australia despite there being no targeted campaign to address the disease. Expanded prescription of ivermectin and public health interventions targeting the few remaining high-prevalence communities would be expected to expedite disease elimination.

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.

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.

A national study on the use of opioid analgesics in dentistry

The aim of this study was to assess the frequency of opioid analgesics prescribed by Brazilian dentists, potential regional differences and their association with socioeconomic and health-related factors. Data for all opioid prescriptions by dentists was obtained from the 2012 database of the National Controlled Substances Management System, regulated by the Brazilian Health Surveillance Agency. The number of defined daily doses (DDD) and DDDs per 1,000 inhabitants per day for each Brazilian state were calculated as the primary outcomes. DDDs were compared by regions and Brazilian states. Spearman's rho correlation coefficient was used to determine the influence of the states' characteristics, such as the Human Development Index; poverty; education; number of dentists per 100,000 inhabitants; visit to the dentist; dental care plan; good or very good oral health; number of pharmaceutical establishments per 100,000/inhabitants; and ability to get all prescribed medications. Data analysis was performed using IBM SPSS Statistics 25.0. A total of 141,161 prescriptions for opioids analgesics by 36,929 dentists were recorded, corresponding to 658,855 doses of opioids dispensed in 2012. The most commonly dispensed opioids were codeine associated with paracetamol (83.2%; n = 117,493). The national DDDs per 1,000 inhabitants per day was 0.0093 (range: 0.0002-0.0216). DDD per 1,000 inhabitants per day was positively associated to visits to dentists (rs = 0.630; P < 0.001) and inversely associated to poverty (rs = -0.624; p = 0.001). There are significant differences in opioid prescriptions in dentistry among the Brazilian states. These differences may be associated with non-clinical factors.

Perceptions, attitudes and factors that influence prescribing by general dentists in Australia: A qualitative study

BACKGROUND

Longitudinal studies of dental prescribing in Australia show that dentists make some inappropriate prescribing choices; literature has shown that dentists tend to overprescribe antibiotics and prescribe for incorrect indications. The unnecessary use of antibiotics is a contributing factor towards the development of antibiotic resistance. The aims of the study were to obtain a greater understanding of the perceptions, attitudes and factors that influence dental prescribing for all major relevant drug classes.

METHOD

Semi-structured interviews of 15 purposively sampled dentists practising in Victoria, Australia were conducted from June-September 2018. Two dentists practised in rural areas and the remainder in urban locations. The range of clinical experience varied from 2.5 to 37 years, with a mean of 13 years. The transcripts were analysed thematically.

RESULTS

Dentists generally preferred amoxicillin as first-line therapy for odontogenic infections, with some confusion about the spectrum and uses of antibiotics. Overprescribing was evident, mostly due to basing judgement for use of antibiotics on symptoms rather than clinical signs. Other factors, such as time pressure, patient expectations, pressure from assistant staff, concern about online criticism and medico-legal considerations, influenced prescribing. Of the dentists who prescribed anxiolytics, most did not have a care protocol for their sedated patients.

CONCLUSION

A variety of prescribing practices were described, and future interventions should target misconceptions around the appropriate use and choice of antibiotics, resources to address the shortfall in knowledge of therapeutics, patient education and staff training, as well as appropriate care and monitoring of sedated patients.

Part 2. Current prescribing trends of dental non-antibacterial medicines in Australia from 2013 to 2016

BACKGROUND

There is limited literature regarding dental prescribing preferences for medicines other than antibiotics. This study aimed to describe the prescribing trends of dispensed prescription medicines by dentists in Australia from 2013 and 2016 and assess adherence to current guidelines.

METHODS

Data were accessed from the Department of Health of all dental prescriptions dispensed under the Pharmaceutical Benefits Scheme (PBS) from 2013 to 2016 and prescribing patterns were analysed. The prescribing rates were standardized to the dose and population.

RESULTS

There was an overall increase in the standardized use of opioid analgesics by almost 30% over the time frame, with the combination paracetamol 500 mg plus codeine 30 mg tablet accounting for the majority of dispensed opioid prescriptions (96.2% in 2016). Dispensed benzodiazepine prescriptions increased by 14.6%.

CONCLUSIONS

The increase in the consumption of opioids is concerning, suggesting that continuing education is required for dentists to better understand their limited role in managing dental pain and potential for abuse. The substantial increase in the dispensed use of benzodiazepines also requires further investigation and there were some drugs prescribed inappropriately and not in accordance with guidelines. Consideration could also be given to reviewing the drugs listed on the PBS for dental prescribing.
