How did COVID-19 impact on dental antibiotic prescribing across England?

Antibiotic prescribing pattern of oral health practitioners before and during the COVID-19 pandemic at Wits Oral Health Centre

The purpose of the study was to determine the antibiotic prescribing pattern of oral health practitioners before and during the Coronavirus disease 2019 (COVID-19) pandemic at Wits Oral Health Centre, South Africa. A retrospective, descriptive study was conducted using a systematic random sample of 698 records of patients who were prescribed antibiotics. The records were categorised into two groups: pre-COVID-19 and COVID-19 pandemic periods. For each group, data collected and analysed included variables such as patient demographics, prescriber discipline, medical history, dental condition, dental procedure, type of antibiotic, dose, frequency, and duration. Most patients in both the pre-COVID-19 and COVID-19 groups (70.3% and 73%, respectively) were healthy. The most common indication for prescribing antibiotics was a painful tooth (58.7%). Amoxycillin and metronidazole remain the antibiotics of choice for most dental conditions. More patients were treated with antibiotics only in the COVID-19 group than the pre-COVID-19 group (46.8% vs 33.7%). A significant proportion of the prescribed antibiotics were not indicated in both the pre-COVID-19 and COVID-19 groups (53.1% and 54.3%, respectively). The increased antibiotic usage during the COVID-19 period, in spite of the decrease in the number of patients consulted, underscores the need for more strategies to be implemented to strengthen antimicrobial resistance surveillance and stewardship initiatives.

The Impact of the COVID-19 Pandemic on Pattern of Antibiotic and Opioid Prescriptions by Dentists in Alberta, Canada

OBJECTIVES

After the shutdown of most dental services during the COVID-19 lockdown, the oral health community was concerned about an increase in prescribing opioids and antibiotics by dentists due to patients' limited access to dental offices. Therefore, the objective of this study was to investigate the impact of COVID-19 pandemic on the pattern of antibiotic and opioid prescriptions by dentists in Alberta, Canada.

METHODS

Data obtained from the Tracked Prescription Program were divided into antibiotics and opioids. Time periods were outlined as pre-, during-, and postlockdown (phase 1 and 2). For the number of prescriptions and average supply, each monthly average was compared to the corresponding prelockdown monthly average, using descriptive analysis. Time series analyses were conducted using regression analyses with an autoregressive error model. Data were trained and tested on monthly observations before lockdown and predicted for during- and postlockdown.

RESULTS

A total of 1.1 million antibiotics and 400,000 opioids dispense were tracked. Decreases in the number of prescriptions during lockdown presented for antibiotics (n = 24,933 vs. 18,884) and opioids (n = 8892 vs. 6051). Average supplies (days) for the antibiotics (n = 7.10 vs. 7.55) and opioids (n = 3.92 vs. 4.05) were higher during the lockdown period. In the trend analyses, the monthly number of antibiotic and opioid prescriptions showed the same pattern and decreased during lockdown.

CONCLUSION

The COVID-19 pandemic altered the trends of prescribing antibiotics and opioids by dentists. The full impact of COVID-19 pandemic on the population's oral health in light of changes in prescribing practices by dentists during and after lockdown warrants further investigation.

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.

Community pharmacists' perceptions on managing people with oral health problems-A prioritisation survey

BACKGROUND

Alternative sources of oral health information are likely to be of benefit to the public, particularly where access to dental services is limited. There is evidence that community pharmacists are willing to advocate for oral health, but it is unclear what is needed to develop this role.

OBJECTIVES

The aims of this study were to obtain the views of community pharmacy staff on the frequency and type of oral health conditions they encounter challenges in management and training/research priorities.

METHODS

An anonymous online survey targeted pharmacy staff and elicited quantitative data related to the types and frequencies of oral health conditions experienced. Participants were stratified by age, gender, ethnicity, experience and setting. Free text responses allowed participants to detail challenging aspects of patient management, their priorities for service development and future research. Reflexive thematic analysis of free text responses identified key themes.

RESULTS

Oral/facial pain and swelling were seen weekly by most respondents, and daily by 28.8%. Other commonly presenting conditions were ulcers, dry-mouth, thrush and denture issues. Challenges in managing oral health conditions included: access to NHS dentistry, awareness of referral pathways, examination/diagnosis and understanding 'Red Flags'.

CONCLUSION

Acute and chronic oral health conditions commonly present to community pharmacists who lack necessary knowledge/training, which may result in missing 'red flag' symptoms for oral cancer or acute facial swellings which can be life threatening. There is a need to support pharmacists, who are willing to act as oral health advocates, in recognition, prevention and onward referral for oral diseases.

Impact of COVID-19 on emergency oral health care in New Jersey

BACKGROUND

The COVID-19 pandemic led to reduced services of private dental practices. The public emergency clinic of Rutgers School of Dental Medicine (RSDM) (Newark, NJ) faced changing demands during various periods of the pandemic.

METHODS

Records of patients visiting the emergency clinic at RSDM during 3 distinct periods (prelockdown, lockdown, teledentistry) from January 10, 2020, through June 30, 2020, were retrospectively reviewed. Qualitative and quantitative attributes pertaining to patient encounters were reviewed and analyzed.

RESULTS

A total of 1,799 records were included in this study. Patient visits increased during the early lockdown but were reduced after the implementation of teledentistry. Trends were noted in patient volume, reasons for visits, treatment needs, symptoms, diagnostic methodology, prescription use, and final disposition of patients.

CONCLUSIONS

The lockdown affected emergency dental clinic services at RSDM. Teledentistry visits played a key role in screening patients and in facilitating the delivery of oral health care and timely follow-ups to patients who needed urgent in-person emergency visits.

PRACTICAL IMPLICATIONS

Data gathered will lead to a better understanding of patients seen in the emergency clinic and can help with long-term planning for both institutional and smaller outpatient clinics during public health emergencies.

The impact of COVID-19 national restrictions on dental antibiotic dispensing trends and treatment activity in England: January 2016 to July 2021

Introduction

Reducing inappropriate antibiotic prescribing tempers the growing threat of antimicrobial resistance. We aimed to quantify the associated impact of COVID-19-related national restrictions in England on dental antibiotic dispensing and describe changes in appointments and modes of delivery of care.

Methods

Interrupted time series analyses were completed using NHS Business Service Authority (NHSBSA) ePACT2 data to measure the associated change in antibiotic dispensing in England following COVID-19-related restrictions (which began March 2020). For face-to-face dental consultations, NHS dental treatment plan (FP17) data were used. For remote consultations during the COVID-19 period, NHSBSA Compass system remote management data were used.

Results

Between January 2016 and February 2020, there was a decreasing trend in antibiotic dispensing (-0.02 per 1000 population per month, P < 0.05). In contrast, there was an increase of 0.98 per 1000 population (P < 0.05) in March. The peak in antibiotic use occurred between June 2020 and July 2020, once the restrictions were eased. At the end of the study period (July 2021), the elevated prescribing trend had not returned to pre-pandemic counterfactual levels, although exhibiting a declining trend. A stable trend in dental treatment plans was seen pre-COVID-19, with a sharp decline coinciding with the restrictions. Dental treatment plans had not yet returned to the higher pre-pandemic levels.

Conclusions

Dental antibiotic prescribing significantly increased with the national COVID-19 restrictions when service delivery was altered with the closure of dental practices and introduction of remote consultations. Teledentistry was likely associated with inappropriate antibiotic prescribing. Continued antimicrobial stewardship and prudent use of antibiotics in dentistry is important.

Dental antibiotics and referrals in general medical practice: Wales 1974-2017

OBJECTIVES

This study aimed to explore trends and predictors for antibiotic prescriptions and referrals for patients seeking dental care at General Medical Practitioners (GMPs) over a 44-year period in Wales, UK.

METHODS

This retrospective observational study analysed data from the nationwide Secure Anonymised Information Linkage Databank of visits to GMPs. Read codes associated with dental diagnoses were extracted from 1974-2017. Data were analysed using descriptive statistics, univariate and multivariable logistic regression.

RESULTS

Over the 44-year period, there were a total of 160,952 antibiotic prescriptions and 2,947 referrals associated with a dental attendance. Antibiotic prescriptions were associated with living in the most deprived (OR 0.91, 95% CI 0.89-0.93) or rural (OR 0.83, 95% CI 0.82-0.84) areas, whereas referrals were associated with living in an urban area (OR 2.16, 95% CI 1.99-2.35) or rural and less deprived area (OR 1.71, 95% CI 1.26-2.33). The number of antibiotic prescriptions decreased over time whereas the number of referrals increased.

CONCLUSIONS

These changes coincide with dental attendance rates at GMPs over the same period and indicate that appointment outcome and repeat patient attendance are linked. Rurality and deprivation may also influence care provided.

CLINICAL SIGNIFICANCE

General medical practices are not the most appropriate place for patients seeking dental care to attend, and efforts should be made to change current practice and policy to support patients to seek care from dental practices. When patients do seek dental care from GMPs they should be encouraged to refer the patient to a dentist rather than prescribe antibiotics as an important element of national antimicrobial stewardship efforts, as well as to discourage repeat attendance.

Changes in Medication Prescribing Due to COVID-19 in Dental Practice in Croatia-National Study

The 2019 coronavirus pandemic (COVID-19) has affected clinical practice and, consequently, drug prescribing in dental practice. We investigated how the pandemic affected the prescribing behavior of dentists in Croatia. Data on prescribing practices for this study were provided by the Croatian Health Insurance Institute. The analysis included the number of prescriptions, costs, and the number of packages prescribed. The World Health Organization's defined daily dose per 1000 inhabitants (DID) per day was used as an objective utilization comparison. During the first pandemic year, prescribing practice changed the most. Wide-spectrum antibiotics, analgesics, and antiseptics showed the highest trend in change. A statistically significant change in prescribing practices during the pandemic period was noted for amoxicillin with clavulanic acid, ibuprofen, and ketoprofen which showed an increase in trend, while cephalexin and diclofenac showed a statistically significant decrease. The highest increase in trend was recorded for azithromycin, at +39.3%. The COVID-19 pandemic has been associated with a marked increase in medication utilization, especially in the first year of the pandemic. The increase in wide-spectrum antibiotic classes needs to be addressed and regulated so that patients accept that antibiotics are not a substitute for dental treatment and dentists always start treatment with narrow-spectrum antibiotics regardless of specific times, as is the case with the pandemic.

Assessment of the Prescriptions of Systemic Antibiotics in Primary Dental Care in Germany from 2017 to 2021: A Longitudinal Drug Utilization Study

(1) Background: Due to increasing antibiotic resistance, the frequency of antibiotic use should be questioned in dentistry and attention paid to the choice of the best suited substance according to guidelines. In Germany, overprescribing of clindamycin was noteworthy in the past. Therefore, the aim of our study was to determine the trend of antibiotic prescriptions in primary dental care. (2) Methods: Prescriptions of antibiotics in German primary dental care from 2017 to 2021 were analysed using dispensing data from community pharmacies, claimed to the statutory health insurance (SHI) funds, and compared with all antibiotic prescriptions in primary care. Prescriptions were analysed based on defined daily doses per 1000 SHI-insured persons per day (DID). (3) Results: Amoxicillin was the most frequently prescribed antibiotic (0.505 DID in 2017, 0.627 in 2021, +24.2%) in primary dental care, followed by clindamycin (0.374 DID in 2017, 0.294 in 2021, -21.4%). Dental prescriptions still made up 56% of all clindamycin prescriptions in primary care in 2021. (4) Conclusions: Our study suggests that the problem of overuse of clindamycin in German dentistry has improved, but still persists.

Changes in Antibiotic Prescribing Patterns in Danish General Practice during the COVID-19 Pandemic: A Register-Based Study

The World Health Organization expressed concern that antimicrobial resistance would increase during the COVID-19 pandemic due to the excessive use of antibiotics. This study aimed to explore if antibiotic prescribing patterns in general practices located in the North Denmark Region changed during the COVID-19 pandemic. The study was conducted as a registry-based study. Data was collected for every antibiotic prescription issued in general practices located in the North Denmark Region during the first year of the pandemic (1 February 2020 to 31 January 2021) and the year prior to the pandemic (1 February 2019 to 31 January 2020). Data were compared regarding antibiotic agents and the type of consultation linked to each antibiotic prescription. Results showed that antibiotic prescriptions decreased by 18.5% during the first pandemic year. The use of macrolides and lincosamides, along with combinations of penicillins and beta-lactamase -sensitive penicillins, was reduced the most. Face-to-face consultations related to an antibiotic prescription decreased by 28.5%, while the use of video consultations increased markedly. In Denmark, COVID-19 restrictions have contributed to both a lower consumption of antibiotics and a change in prescription patterns in general practice. Probably some of the COVID-19 -preventing initiatives could be of importance moving forward in the fight against antimicrobial resistance.

Moving the needle on dental antibiotic overuse in Canada post COVID-19

Antimicrobial resistance due to over-prescribing in health care, including in dentistry, has been acknowledged as one of the top ten threats to global health by the World Health Organization. Dentistry is responsible for approximately 10% of antibiotics prescribed worldwide and research has shown up to 80% of antibiotics prescribed by dentists may be unnecessary. During the early months of the coronavirus disease 2019 pandemic, when dental offices handled only dental emergencies, it is probable that antibiotics were prescribed more readily and for longer duration to defer treatment for non-urgent cases. These unprecedented times strengthened the realization that strong dental antimicrobial stewardship practises are required in Canada to keep antimicrobial overuse under control. In countries, such as the United Kingdom and Australia, significant work is ongoing in this regard. Canada has made progress in developing tools for antimicrobial stewardship specifically for physicians in community settings, where the vast majority of antibiotics are prescribed, and it is now time to pay attention to antimicrobial stewardship in the field of dental care. Investments in developing a national level dental prescription database, along with monitoring, education and feedback mechanisms, can strongly support moving the needle on dentist-driven antibiotic overuse in Canada.

Did the March 2020 lockdown cause an increase in patients presenting to the emergency department with odontogenic pain and infection? A single centre, retrospective analysis

On the 25 March 2020 the Chief Dental Officer (CDO) published guidance to restrict the provision of routine dental care in England due to the rapid spread of the severe acute respiratory syndrome Coronavirus 2 (COVID-19). We analysed the impact of the pandemic on the number of patients presenting with odontogenic pain and infection to the emergency department (ED) of an urban-based teaching hospital, the Bristol Royal Infirmary (BRI). Furthermore, we investigated the severity of infection at first presentation to the ED. The study period encompassed three phases that represented the stages of pandemic restrictions: phase 1 prior to lockdown measures, with no restrictions to dental practice; phase 2 during the government lockdown, with the severest restrictions on dental practices; and phase 3 following the ease of lockdown measures, with return to limited dental services. Data were collected retrospectively from electronic patient records (EPR) regarding adult patients presenting to the ED with dental pain. The rate of presentations (per week) was calculated for each timepoint and compared. A severity score was assigned to each patient using a grading system based on signs of clinical infection and treatment modality. Patients' presentations were analysed at each phase of the pandemic. There was a 42.8% increase in attendance with oral facial pain and infection to ED from phases 1 to 3. The COVID-19 pandemic resulted in restrictions to routine primary dental care services, which were deemed necessary to reduce the spread of the virus. However, this increased demand on secondary care services, as patients increasingly struggled to access primary dental care to manage dental pain.

Understanding the impact of COVID-19 on dental antibiotic prescribing across England: 'it was a minefield'

Introduction The COVID-19 pandemic impacted significantly on dental service delivery across England.

Objective To explore how and why the pandemic affected antibiotic prescribing by primary care dentists.

Methods Mixed-methods study: secondary analysis of routinely collected NHS dental antibiotic prescribing data from before and during the pandemic; and an online survey of dentists (NHS and private) across England's regions.

Results Dental antibiotic prescribing increased 22% in the pandemic's first year, with regional variation from a 12.1% increase in London to 29.1% in East of England. Of 159 dentists surveyed, 60% had prescribed 'many more' antibiotics. Some urgent dental centres required antibiotics before accepting referrals, irrespective of clinical appropriateness. Diagnosing remotely was hard. Antibiotics were used to delay aerosol generating procedures and fill gaps in services. Widespread frustration existed.

Discussion Maintaining access to urgent dental care during a future pandemic would include availability of high-grade personal protective equipment for dental teams. Everyone must understand the impact of restricted dental access on antibiotic overprescribing and hence antibiotic resistance.

Conclusion Reduced dental access and changes in dental service delivery because of the pandemic increased antibiotic prescribing. Ensuring uninterrupted access for all to effective urgent dental care is an important element of global efforts to tackle antibiotic resistance.

Remote management of patients during the COVID-19 pandemic resulted in increased antibiotic prescribing in each of England's regions. Most dentists were not confident managing patients with acute dental conditions remotely. Ensuring access to face-to-face dentistry is an important part of efforts to tackle antibiotic resistance.

Dentists felt frustrated about being prevented from providing the dental procedures needed to provide safe and effective care to people in pain. Many also expressed concern about the impact of increased antibiotic prescribing on antibiotic resistance and their experience of increased patient expectation that antibiotics are appropriate for toothache.

Preparedness plans for future pandemics should recognise that antibiotics are not a substitute for dental procedures and dentistry was the only part of the NHS to experience an increase in antibiotic prescribing during the COVID-19 pandemic. Planners should aim to ensure sufficient face-to-face urgent dental care provision immediately upon implementation of pandemic restrictions.

The impact of COVID-19 on individual oral health: a scoping review

BACKGROUND

Poor oral health due to dental caries is one of the most prevalent non-communicable diseases worldwide. It has a significant impact on individuals across the lifespan and is a leading cause of preventable hospitalizations. The impacts of COVID-19 on oral health at the practice level are well documented, but gaps in understanding the impact on individual oral health remain. This review addresses this gap.

METHODS

Using a JBI scoping review process we mapped and summarized the evidence to identify the impact of COVID-19 on individual oral health. Key search terms were developed, and searches were undertaken by an experienced research librarian.

RESULTS

The 85 included studies were conducted in 23 countries from 5 regions across the world classified using the United Nations Geoscheme system. The majority (82/85) were quantitative, 2 were reviews and there was one qualitative interview study. Cross-sectional surveys were the most common data collection approach followed by an analysis of clinical data, analysis of internet trends and other online methods. Five key areas were identified including changes to the provision of emergency dental services, provision of routine oral health services, oral hygiene maintenance at home, changes in dietary preferences, alternative models of dental provision and help-seeking and attitudes towards dental care in the future.

CONCLUSIONS

This scoping review has demonstrated that the pandemic has impacted on oral health at the individual level. It is important that we are aware of these impacts and ensure that support systems are in place to overcome future periods where access to dental care might be compromised. The provision of preventive care remains a vital first step in ensuring good overall oral health as is paramount during periods where access to dental treatment might be limited.

Impact of the COVID-19 Pandemic on Antibiotic Prescribing by Dentists in Galicia, Spain: A Quasi-Experimental Approach

Background: Antibiotic resistance is one of the most pressing public health problems. Health authorities, patients, and health professionals, including dentists, are all involved in its development. COVID-19 pandemic restrictions on dental care may have had repercussions on antibiotic prescribing by dentists. The aim of this study was to assess the impact of the COVID-19 pandemic on antibiotic prescribing by dentists, and to review antibiotic consumption according to the WHO Access, Watch, Reserve classification. We conducted a natural, before-and-after, quasi-experimental study, using antibiotic prescription data covering the period from January 2017 to May 2021. A segmented regression analysis with interrupted time series data was used to analyse the differences between the numbers of defined daily doses (DDD) of antibiotics prescribed monthly. The outcomes showed an immediate significant decrease in overall antibiotic prescribing by primary-care dentists during lockdown, followed by a non-significant upward trend for the next year. This same pattern was, likewise, observed for Access and Watch antibiotics. COVID-19 pandemic restrictions on dental care influenced the prescription of antibiotics. During confinement, an initial decrease was observed, this trend changed when in person consultations were recovered. It might be beneficial to analyse the prescription of antibiotics using the WHO AWaRe classification, in order to monitor their appropriate use.

Top 50 covid and oral health articles: A 2021 altmetric analysis

Objectives

There is a world of information at our disposal, and it is increasingly difficult to transform this dull amount of data into knowledge. How to be constantly actualized? This study aims to create an altmetric list of the top 50 articles related to COVID-19 and oral health.

Methods

Research of terms COVID-19 and oral health was done using Dimensions app. Results were ranked in altmetric citations and analyzed through Microsoft Excel. Some tables and graphics were created. Graphical illustration of keywords was created using VOSviewer.

Results

Some interesting facts can be seen, like growing interest in dental aerosols, perspectives, and virucidal activity of some mouthwashes.

Conclusions

Altmetric analysis is a helpful manner to scientific updates, supplementing bibliometric analysis. A terrific manner to see trends. The scientific community goes to great lengths to solve problems with dental aerosols, particularly to reduce contamination. Some adjustments to dental office and the use of barriers are recommended.

The impact of the COVID-19 pandemic on antimicrobial prescribing at a specialist paediatric hospital: an observational study

BACKGROUND

The COVID-19 pandemic has severely impacted healthcare delivery and there are growing concerns that the pandemic will accelerate antimicrobial resistance.

OBJECTIVES

To evaluate the impact of the COVID-19 pandemic on antibiotic prescribing in a tertiary paediatric hospital in London, UK.

METHODS

Data on patient characteristics and antimicrobial administration for inpatients treated between 29 April 2019 and Sunday 28 March 2021 were extracted from the electronic health record (EHR). Interrupted time series analysis was used to evaluate antibiotic days of therapy (DOT) and the proportion of prescribed antibiotics from the WHO 'Access' class.

RESULTS

A total of 23 292 inpatient admissions were included. Prior to the pandemic there were an average 262 admissions per week compared with 212 during the pandemic period. Patient demographics were similar in the two periods but there was a shift in the specialities that patients had been admitted to. During the pandemic, there was a crude increase in antibiotic DOTs, from 801 weekly DOT before the pandemic to 846. The proportion of Access antibiotics decreased from 44% to 42%. However, after controlling for changes in patient characteristics, there was no evidence for the pandemic having an impact on antibiotic prescribing.

CONCLUSIONS

The patient population in a specialist children's hospital was affected by the COVID-19 pandemic, but after adjusting for these changes there was no evidence that antibiotic prescribing was significantly affected by the pandemic. This highlights both the value of routine, high-quality EHR data and importance of appropriate statistical methods that can adjust for underlying changes to populations when evaluating impacts of the pandemic on healthcare.

Outcomes to evaluate care for adults with acute dental pain and infection: a systematic narrative review

OBJECTIVE

To identify outcomes reported in peer-reviewed literature for evaluating the care of adults with acute dental pain or infection.DesignSystematic narrative review.

SETTING/PARTICIPANTS

Primary research studies published in peer-reviewed literature and reporting care for adults with acute dental pain or infection across healthcare settings. Reports not in English language were excluded.

STUDY SELECTION

Seven databases (CINAHL Plus, Dentistry and Oral Sciences Source, EMBASE, MEDLINE, PsycINFO, Scopus, Web of Science) were searched from inception to December 2020. Risk of bias assessment used the Critical Appraisal Skills Programme checklist for randomised controlled trials and Quality Assessment Tool for Studies of Diverse Design for other study types.

OUTCOMES

Narrative synthesis included all outcomes of care for adults with acute dental pain or infection. Excluded were outcomes about pain management to facilitate treatment, prophylaxis of postsurgical pain/infection or traumatic injuries.

RESULTS

Searches identified 19 438 records, and 27 studies (dating from 1993 to 2020) were selected for inclusion. Across dental, pharmacy, hospital emergency and rural clinic settings, the studies were undertaken in high-income (n=20) and low/middle-income (n=7) countries. Two clinical outcome categories were identified: signs and symptoms of pain/infection and complications following treatment (including adverse drug reactions and reattendance for the same problem). Patient-reported outcomes included satisfaction with the care. Data collection methods included patient diaries, interviews and in-person reviews.

DISCUSSION

A heterogeneous range of study types and qualities were included: one study, published in 1947, was excluded only due to lacking outcome details. Studies from dentistry reported just clinical outcomes; across wider healthcare more outcomes were included.

CONCLUSIONS

A combination of clinical and patient-reported outcomes are recommended to evaluate care for adults with acute dental pain or infection. Further research is recommended to develop core outcomes aligned with the international consensus on oral health outcomes.

Patterns of dental antibiotic prescribing in 2017: Australia, England, United States, and British Columbia (Canada)

OBJECTIVE

Our objective was to compare patterns of dental antibiotic prescribing in Australia, England, and North America (United States and British Columbia, Canada).

DESIGN

Population-level analysis of antibiotic prescription.

SETTING

Outpatient prescribing by dentists in 2017.

PARTICIPANTS

Patients receiving an antibiotic dispensed by an outpatient pharmacy.

METHODS

Prescription-based rates adjusted by population were compared overall and by antibiotic class. Contingency tables assessed differences in the proportion of antibiotic class by country.

RESULTS

In 2017, dentists in the United States had the highest antibiotic prescribing rate per 1,000 population and Australia had the lowest rate. The penicillin class, particularly amoxicillin, was the most frequently prescribed for all countries. The second most common agents prescribed were clindamycin in the United States and British Columbia (Canada) and metronidazole in Australia and England. Broad-spectrum agents, amoxicillin-clavulanic acid, and azithromycin were the highest in Australia and the United States, respectively.

CONCLUSION

Extreme differences exist in antibiotics prescribed by dentists in Australia, England, the United States, and British Columbia. The United States had twice the antibiotic prescription rate of Australia and the most frequently prescribed antibiotic in the US was clindamycin. Significant opportunities exist for the global dental community to update their prescribing behavior relating to second-line agents for penicillin allergic patients and to contribute to international efforts addressing antibiotic resistance. Patient safety improvements will result from optimizing dental antibiotic prescribing, especially for antibiotics associated with resistance (broad-spectrum agents) or C. difficile (clindamycin). Dental antibiotic stewardship programs are urgently needed worldwide.

Triage and urgent dental care for COVID-19 patients in the Hospital District of Helsinki and Uusimaa

OBJECTIVE

This paper describes and reports the patient-specific characteristics of an urgent dental care clinic for COVID-19 infected, suspected, exposed or quarantined patients from March to December 2020 in the Hospital District of Helsinki and Uusimaa, Finland.

MATERIAL AND METHODS

The triage and the treatment protocol were established based on the scientific data. Patient files were evaluated from the hospital district's electronic medical record system. IBM SPSS software was used for statistical analysis.

RESULTS

There were 1114 consultations and 257 visits at the clinic. Most of the patients were generally healthy with mean age of 35, had toothache and were suspected to be SARS-CoV-2 positive. Seventeen of the patients received positive tests for COVID-19 infection. The main treatment was tooth extraction, mostly due to caries. Statistically significant differences between COVID-19 infected and other patients occurred in age (45 vs 34 years-of-age, p = .009) and number of teeth (25 vs 28, p = .031). No SARS-CoV-2 infection transmission chains were traced to the clinic.

CONCLUSION

During the challenging pandemic time, patients were carefully screened by specialists in clinical dentistry and treated safely and effectively. Patient-specific characteristics revealed no differences between COVID-19 infected and other patients in terms of symptoms or treatment needs.

Sustained Improvements in Antimicrobial Therapy and Clinical Outcomes following a Pharmacist-Led Antimicrobial Stewardship Intervention: Uncontrolled Before–After Study

Our antimicrobial pharmacist-led intervention included: (a) a structured review of antibiotic prescriptions; (b) educating prescribers on antimicrobial therapy; (c) monthly reporting of department-level rates of blood sampling for culture. Daily review began in May 2018 and was discontinued after 10 months; however, the other interventions were conducted throughout the study period. This study aimed to evaluate the sustained impact of pharmacist’s interventions on antimicrobial therapy and clinical outcomes between the baseline (May–December 2017), intervention (May–December 2018), and post-intervention (May–December 2019) periods. The rate of blood culture collections before starting antipseudomonal agent therapy was significantly increased from the baseline to post-intervention periods (71% vs. 85%, p < 0.001). Antipseudomonal agent therapy was more frequently de-escalated in the post-intervention period than in the baseline period (73% vs. 54%, p = 0.038). Total use of antipseudomonal agents was reduced from the baseline to intervention periods and persisted during the post-intervention period (50.5 vs. 41.8 and 42.6 DDD per 1000 patient-days, p = 0.016 and p = 0.022, respectively). During the study period, there were significant reductions in the incidence of hospital-acquired Clostridioides difficile infection (1.12, 0.54, and 0.51 per 10,000 patient-days, respectively, p = 0.031) and 30-day mortality with bacteremia (19%, 18%, and 12%, respectively, p = 0.005). Our pharmacist-led interventions sustainably achieved appropriate antimicrobial therapy and improved clinical outcomes.

Pros and Cons of CAD/CAM Technology for Infection Prevention in Dental Settings during COVID-19 Outbreak

The purpose of this commentary is to update the evidence reported in our previous review on the advantages and limitations of computer-aided design/computer-aided manufacturing technology in the promotion of dental business, as well as to guarantee patient and occupational safety. The COVID-19 pandemic led to an unprecedented focus on infection prevention; however, waves of COVID-19 follow one another, asymptomatic cases are nearly impossible to identify by triage in a dental setting, and the effectiveness of long-lasting immune protection through vaccination remains largely unknown. Different national laws and international guidelines (mainly USA-CDC, ECDC) have often brought about dissimilar awareness and operational choices, and in general, there has been very limited attention to this technology. Here, we discuss its advantages and limitations in light of: (a) presence of SARS-CoV-2 in the oral cavity, saliva, and dental biofilm and activation of dormant microbial infections; (b) the prevention of SARS-CoV-2 transmission by aerosol and fomite contamination; (c) the detection of various oral manifestations of COVID-19; (d) specific information for the reprocessing of the scanner tip and the ward from the manufacturers.

'You had to do something': prescribing antibiotics in Scotland during the COVID-19 pandemic restrictions and remobilisation

Introduction The COVID-19 pandemic brought about seismic change for dentistry including the direction to provide remote advice and prescribe analgesia and antimicrobials. The possibilities for care have widened, but the impact of both restrictions and remobilisation on antibiotic prescribing is not known.Aims To report the impact of COVID-19 restrictions and remobilisation on dental antibiotic prescriptions and explore dentists' intentions and attitudes towards antibiotic prescribing.Design and setting Public Health Scotland national prescribing and claims data are reported alongside an online survey of Scottish general and public health service dentists including closed and open-ended questions.Results Antibiotic prescribing rose by 49% following the suspension of routine dental care, to a peak of 34,993 antibiotics (July 2020). The data also show that since the remobilisation of NHS dental care, antibiotic prescribing remains raised at levels around 28% higher than pre-pandemic. The survey highlights dentists' frustrations and concerns about this increased use of antibiotics. Most dentists intend to reduce their prescribing; however, significant challenges to this being realised were raised.Conclusions The previous success within dentistry to protect against the development of antimicrobial resistance has suffered a knock-back during the pandemic. A renewed focus on reducing unnecessary antibiotics within dentistry is required but, crucially, needs to be approached sensitively alongside the current backdrop of challenges within the service.

The Impact of COVID-19 on Outpatient Antibiotic Prescriptions in Ontario, Canada; An Interrupted Time Series Analysis

Background

The coronavirus disease 2019 (COVID-19) pandemic has potentially impacted outpatient antibiotic prescribing. Investigating this impact may identify stewardship opportunities in the ongoing COVID-19 period and beyond.

Methods

We conducted an interrupted time series analysis on outpatient antibiotic prescriptions and antibiotic prescriptions/patient visits in Ontario, Canada, between January 2017 and December 2020 to evaluate the impact of the COVID-19 pandemic on population-level antibiotic prescribing by prescriber specialty, patient demographics, and conditions.

Results

In the evaluated COVID-19 period (March–December 2020), there was a 31.2% (95% CI, 27.0% to 35.1%) relative reduction in total antibiotic prescriptions. Total outpatient antibiotic prescriptions decreased during the COVID-19 period by 37.1% (95% CI, 32.5% to 41.3%) among family physicians, 30.7% (95% CI, 25.8% to 35.2%) among subspecialist physicians, 12.1% (95% CI, 4.4% to 19.2%) among dentists, and 25.7% (95% CI, 21.4% to 29.8%) among other prescribers. Antibiotics indicated for respiratory infections decreased by 43.7% (95% CI, 38.4% to 48.6%). Total patient visits and visits for respiratory infections decreased by 10.7% (95% CI, 5.4% to 15.6%) and 49.9% (95% CI, 43.1% to 55.9%). Total antibiotic prescriptions/1000 visits decreased by 27.5% (95% CI, 21.5% to 33.0%), while antibiotics indicated for respiratory infections/1000 visits with respiratory infections only decreased by 6.8% (95% CI, 2.7% to 10.8%).

Conclusions

The reduction in outpatient antibiotic prescribing during the COVID-19 pandemic was driven by less antibiotic prescribing for respiratory indications and largely explained by decreased visits for respiratory infections.

Effect of Antimicrobial Stewardship on Oral Quinolone Use and Resistance Patterns over 8 Years (2013-2020)

Since 2014, several global and national guidelines have been introduced to address the problem of antimicrobial resistance. We conducted a campaign in a tertiary hospital to promote appropriate quinolone use through educational lectures in 2018. The aim of this retrospective study was to evaluate the changes in the following: prescription characteristics, trend of oral quinolone use, and antibiotic susceptibility of bacteria from 2013 to 2020. Antimicrobial use was assessed as days of therapy per 1000 patient-days. We found a significant reduction in unnecessary antibiotic prescriptions between December 2013 and December 2020. Significant negative trends were detected in the use of quinolones over 8 years (outpatients, coefficient = −0.15655, p < 0.001; inpatients, coefficient = −0.004825, p = 0.0016). In particular, the monthly mean use of quinolones among outpatients significantly decreased by 11% from 2013 to 2014 (p < 0.05) and reduced further by 31% from 2017 to 2020 (p < 0.001). A significant positive trend was observed in the susceptibility of Pseudomonas aeruginosa to levofloxacin (p < 0.001). These results demonstrate that the use of oral quinolones was further reduced following educational intervention and the bacterial susceptibility improved with optimal quinolone usage compared to that in 2013.

Provision of dental care by public health dental clinics during the COVID-19 pandemic in Alberta, Canada

OBJECTIVES

This study aims to describe dental services provided to a low income population in dental public health settings during the first wave of COVID-19 pandemic in Alberta, Canada.

METHODS

Routinely collected clinical data were recorded by dentists in electronic medical record files at Alberta's two Public Health Dental Clinics (PHDCs). Patient contact was via teledentistry or in person, respecting phased provincial pandemic restrictions. A descriptive analysis of data relating to all patients contacting PHDC with dental problems between 17 March - 31 October 2020 was undertaken and compared to equivalent pre-COVID 2019 data.

RESULTS

In the period examined, 851 teledentistry consultations and 1031 in person visits were performed. Compared to the same period in 2019, 46% fewer patients were treated, representing a decrease in dental procedures: tooth extractions (17%), silver diamine fluoride applications (17%), endodontic treatments (82%) and fillings (84%). By contrast, prescriptions increased by 66% overall; representing 76%, 121% and 44% in antibiotics, non-opioid analgesics, and opioid analgesics respectively. In both years, antibiotics were the most prescribed drugs (66% in 2019 versus 62% in 2020) followed by non-opioid analgesics (28% in 2019 versus 33% in 2020); opioids accounted for the remainder (6.5% in 2019 and 5% in 2020). The largest drug prescription increases occurred during April-May 2020, when access to care was most restricted: antibiotics and non-opioid analgesics were 300% and 738% higher than the same time in 2019.

CONCLUSIONS

Teledentistry and pharmacotherapy were used to triage and organise dental patients accessing care during the early stages of the pandemic. However, teledentistry did not replace definitive in person dental treatment, particularly for low income populations with high incidence of toothache and odontogenic infection. Reduced provision of dental procedures was accompanied by an increase in drug prescribing. Expedient access to care must be provided to address the dental needs of this population avoiding risks of further complications associated with infection and overprescribing antibiotics and opiates.

Co-Developing an Antibiotic Stewardship Tool for Dentistry: Shared Decision-Making for Adults with Toothache or Infection

Dentistry is responsible for around 10% of antibiotic prescribing across global healthcare, with up to 80% representing inappropriate use. Facilitating shared decision-making has been shown to optimise antibiotic prescribing (antibiotic stewardship) in primary medical care. Our aim was to co-develop a shared decision-making antibiotic stewardship tool for dentistry. Dentists, patients and other stakeholders prioritised factors to include in the new tool, based on previous research (a systematic review and ethnographic study) about dentists’ decision-making during urgent appointments. Candidate behaviour-change techniques were identified using the Behaviour Change Wheel and selected based on suitability for a shared decision-making approach. A ‘think aloud’ study helped fine-tune the tool design and Crystal Marking ensured clarity of messaging. The resulting paper-based worksheet for use at point-of-care incorporated various behaviour change techniques, such as: ’information about (and salience of) health consequences’, ‘prompts and cues’, ‘restructuring the physical (and social) environment’ and ‘credible sources’. The think aloud study confirmed the tool’s acceptability to dentists and patients, and resulted in the title: ‘Step-by-step guide to fixing your toothache.’ Further testing will be necessary to evaluate its efficacy at safely reducing dental antibiotic prescribing during urgent dental appointments in England and, with translation, to other dental contexts globally.

Dentists deployed: an insider's perspective of life on the NHS front line

The COVID-19 pandemic has stretched and overburdened healthcare services within the UK. This national crisis has led to the widespread redeployment of healthcare workers and reorganization of services throughout the NHS in the UK. The flexible and altruistic nature of healthcare workers has been inspiring, and central in the UK's response to the COVID-19 pandemic. This article describes the 'first-hand' experience of a secondary care dentist, highlighting the redeployment journey to the emergency department (ED) of a major trauma hospital in the North-West of England during the first wave of the COVID-19 pandemic.

Frontline experiences and perceptions of Urgent Dental Care centre staff in England during the COVID-19 pandemic: a qualitative study

Introduction Following the World Health Organisation declaration of COVID-19 as a global pandemic, routine dental care in the UK ceased, and Urgent Dental Care centres (UDCs) were established to offer remote and face-to-face urgent dental treatment for those in need.Aim To explore perceptions and psychosocial experiences of frontline staff providing care at UDCs in England during COVID-19.Method A qualitative research study using a phenomenological approach. Semi-structured interviews were conducted remotely. Using line-by-line coding, data were analysed using a hybrid approach that incorporated both a deductive, theoretical process and an inductive, data-driven process.Results Participants included 29 dentists and nine dental nurses from UDCs across England. Twelve themes were identified and grouped into positive and negative experiences. Positive experiences were: role fulfilment and having a sense of purpose; team unity and collective coping strategies; and strategic teamwork and preparedness for effective organisation of care. Negative experiences included: feeling undervalued and frustrated due to fragmented guidance and communication; sense of unfairness generated by relational challenges; patient demand outstripping UDC capacity; complex decision-making; uncertainty over safety; suffocating PPE hindering effective communication; ineffective communication channels across healthcare sectors; lack of commitment to remote video consultations; and variable referral quality.Conclusions Participants reported experiencing a number of emotional challenges that appeared to be exacerbated by an unsupportive environment, often due to lack of leadership. However, positive experiences and coping strategies were also identified. Collective and sustained efforts at system level to improve the resilience and mental wellbeing of the current and future dental workforce and integration of dentistry into wider healthcare infrastructures are needed.

COVID-19 Pandemic: The Urgent Dental Hub experience from a primary care perspective

In response to the nationwide lockdown on 23 March 2020 in the UK, urgent dental hubs (UDHs) were established in the community to provide emergency dental care.Consecutive referrals to a primary care UDH were prospectively analysed over a one-month period, from 18 May 2020 to 18 June 2020.Of 400 referrals received, the most common were in relation to pain (87%). In 63% neither a radiograph nor photograph was provided with the referral. Seventy percent of patients were telephone triaged within 24 hours of receipt of referral. Fifty-three percent of referrals were accepted for face-to-face treatment, of which 69% were treated by extraction. Of rejected referrals (n=179; 45%), 79% were due to symptoms having settled or being manageable by the time of triage. A small number of referrals were redirected for specialist care. Referrals that were accepted were more likely to have been prescribed antibiotics and less likely to have been referred by the general dental practitioner (GDP) they regularly saw (p <0.01).Patients that were older and those that identified themselves as not having a regular GDP were less likely to have been referred to an UDH. The quality of referrals was poor and there may be a role for virtual consultations moving forwards. We found pre-referral antimicrobial prescriptions were high and a confused public health message may have been sent.

Factors, Perceptions and Beliefs Associated with Inappropriate Antibiotic Prescribing in German Primary Dental Care: A Qualitative Study

Dentists account for up to 10% of all prescribed antibiotics in primary care, with up to 80% being inappropriate. Targeted approaches to change prescription behavior are scarce. This study aimed at identifying specific barriers and facilitators for prudent antibiotic use in German dentistry by using qualitative methods. Nine in-depth interviews and two focus group discussions with another nine dentists were conducted and analyzed thematically. Dentists described being conflicted by the discordance of available treatment time and the necessity of thorough therapy. Lacking the opportunity of follow-up led to uncertainty. Dentists felt a lack of medical competency concerning prophylaxis for infectious endocarditis. A lack of empowerment to make therapeutic decisions interfered with guideline-conformity. The communication with fellow physicians is conflictual and improvement was wished for. In consequence, dentists felt pressure by potential medico-legal liability. Patients demanding quick and easy pain relief put extra strain on the interviewed dentists. Our hypotheses concord with preliminary data, mainly from the UK, but highlighted specifically medico-legal concerns and interprofessional communication as even greater barriers as described before. Tailored interventional concepts based on our findings may have the potential to lower antibiotic prescriptions in German primary dental care.

Dentist Related Factors Associated with Implementation of COVID-19 Protective Measures: A National Survey

Little is known about the extent to which dentists have implemented COVID-19 infection control guidelines and the factors influencing this process in daily practice. This national online survey assessed the implementation of enhanced infection control guidelines in daily practice, and explored dentist related factors influencing their application, more specifically dentist infection status and their perceived risk of cross-infection in the dental setting. The survey was validated, pretested and carried out in 2020. A total of 1436 dentists participated, of whom 9.1% presumably had COVID-19 infection experience. At least 75% of dentists complied with the core part of the recommended protective measures protocol. For each patient treated during the pandemic, an additional cost of 10–30 EUR (86.7%) and an extra time of 10–30 min (70.7%) was estimated. A stepwise binary logistic regression analysis revealed that dentists assumed to have experienced COVID-19 reported a higher self-perceived risk of virus acquisition (β = 2.090; p = 0.011), lower concern of getting infected (β = 0.576; p = 0.027), and lower confidence in being able to prevent disease transmission in the dental setting (β = 0.535; p = 0.022). Some parts of the protective measures were more difficult to apply than others; however, there was no indication of increased disease acquisition in the dental setting.

Analysis of primary care prescription trends in England during the COVID-19 pandemic compared against a predictive model

Objectives

The COVID-19 pandemic has had an unprecedented impact across primary care. Primary care services have seen an upheaval, and more and more patients are engaging in telephone consultations in order to maintain social distancing. In the present study, we seek to quantify the effect of the pandemic on primary care prescribing.

Design

We conducted a retrospective analysis of the English Prescribing Dataset from January 2014 to November 2020, totalling 7 542 293 921 prescriptions. Data were separated into prepandemic and pandemic sets. A Holt-Winters predictive model was used to forecast individual drug prescribing based on historic trends. Observed data were compared with the forecast quantitatively and qualitatively.

Setting

All prescriptions signed in England and dispensed during the years 2014–2020.

Participants

All residents of England who received a prescription from primary care facilities during 2014–2020.

Results

Prescribing of numerous health-critical medications was above predicted in March 2020, including salbutamol (53.0% (99% CI (41.2% to 66.9%))), insulin aspart (26.9% (99% CI (18.5% to 36.6%))) and tacrolimus (18.6% (99% CI (8.3% to 31.1%))). Medications for end-of-life symptom control increased in April, including levomepromazine hydrochloride (94.7% (99% CI (54.6% to 163.0%))). Medications requiring face-to-face visits decreased, including the local anaesthetic bupivacaine hydrochloride (86.6% (99% CI (89.3% to 82.0%))). There was no observed change in medications relating to type 2 diabetes, hypertension or mental health conditions.

Conclusions

Significantly increased prescribing of several medications was observed, especially among those critical for health. A dramatic spike in end-of-life prescribing highlights the adversity faced by community practitioners during 2020. Medications involving face-to-face consultations declined, as did contraceptives, travel-related vaccines and drugs used in dementia and Parkinson’s disease. Drugs relating to type 2 diabetes, hypertension and mental health were unchanged.

The potential impact of the COVID-19 pandemic on antimicrobial resistance and antibiotic stewardship

The rapid emergence and spread of antimicrobial resistance continue to kill an estimated 700,000 people annually, and this number is projected to increase ten-fold by 2050. With the lack of data, it is uncertain how the COVID-19 pandemic will affect antimicrobial resistance. Severe disruption of research, innovation, global health programs, and compromised antimicrobial stewardship, infection prevention and control programs, especially in low-and middle-income countries, could affect antimicrobial resistance. However, factors such as strict lockdown, social distancing, vaccination, and the extensive implementation of hand hygiene and face masks, with limited international travel and migration, may also contribute to decreasing AMR. Although the impact of COVID-19 on AMR is global, the adverse effect is likely to be worse in LMICs. In this article, we explore the possible impact of the current pandemic on antibiotic resistance.

Antibiotics and toothache: a social media review

OBJECTIVES

Antibiotics are inappropriate for the treatment of toothache, yet many seek them. Social media allows users to express their opinions, share experiences and offer support. This study used social media to investigate the public's experiences of, and attitudes towards, antibiotics for toothache.

METHODS

A systematic search of posts on Facebook and Twitter was undertaken. Eligibility criteria were applied to select relevant social media posts for thematic analysis of word content. An inductive descriptive coding system was developed from the data and exemplary quotes were identified to illustrate the themes and subthemes identified. Key findings Searches identified 174 posts, of which 144 were selected for analysis. Five themes were identified: experience and expectations, self-care and professional treatment, access to dental care, quality of life and coping strategies. The belief that antibiotics are an appropriate treatment for a toothache was widespread. Antibiotic-seeking behaviour was related to access to professional dental care, including avoiding dental appointments due to dental anxiety and the perceived affordability of dentistry. A range of strategies to cope with the severe impact toothache was having on people's quality of life were identified, from prayer to antibiotics.

CONCLUSIONS

Social media is used extensively to seek antibiotics, avoid dental treatment and provide support to people with toothache. A general belief that antibiotics are an appropriate and necessary treatment for toothache exists. This improved understanding about the factors driving antibiotic-seeking behaviour provides new targets for the development of approaches to tackling antibiotic resistance, by reducing unnecessary antibiotic use in dental clinics and beyond.

Community Antibiotic Use at the Population Level During the SARS-CoV-2 Pandemic in British Columbia, Canada

Background

The objective of this study was to examine the aggregate rates of antibiotic use at the population level and compare these rates over time against historical averages to identify the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the resulting control measures on community prescribing.

Methods

We collected antibiotic prescriptions and physician office visits from January 1, 2016, to July 21, 2020. We calculated monthly prescription rates stratified by sex, age group, profession, diagnosis type, and antibiotic class. We looked at monthly prescription rate as a moving average over time. Using the interrupted time series analysis method, we estimated the changes in prescription rates after March 2020.

Results

The moving average of overall monthly prescription rates during January–June 2020 was below the minimum of the historical years’ moving averages (2016–2019). We observed a >30% reduction in overall monthly prescription rates in April, May, and July of 2020 compared with the same months of 2019. We observed that overall monthly prescription rates experienced a significant level change of –12.79 (P < .001) during the coronavirus disease 2019 pandemic after March 2020, with the greatest level change being –18.02 among children 1–4 years of age (P < .001). We estimated an average –5.94 (P < .001) change in respiratory tract infection (RTI)–associated monthly prescription rates after March 2020. Overall prescription rates comparing January–July 2019 and their 2020 counterparts showed a decrease in monthly prescribing ranging from –1 to –5 for amoxicillin, amoxicillin and enzyme inhibitors, azithromycin, clarithromycin, and sulfamethoxazole.

Conclusions

In British Columbia, Canada, overall and RTI-specific monthly antibiotic prescription rates declined significantly during April–July 2020 compared with the same months in prepandemic years.

Involvement of Tunisian General Practitioners in the Management of Patients at Risk of Infective Endocarditis: A Cross-Sectional Study

Objectives

This work aimed to estimate the knowledge and practice of general dentists in the governorate of Manouba regarding the management of patients at risk of infective endocarditis.

Materials and Methods

A survey involving private sector general dentists in the governorate of Manouba was performed. It contained 21 questions, and it was addressed to 111 dentists. Only 82 dentists responded. To carry out the descriptive study, we used the SPSS software version 21.0.

Results

Our results proved the lack of knowledge among dentists in the governorate of Manouba with regard to the management of patients at risk of infective endocarditis. An overestimation of the risk and an overprescription of antibiotic were found in order to ensure an over-protection for the patients as well as the dentist. In fact, 85.4% of these dentists prescribed antibiotic prophylaxis for the two groups of patients (high risk and moderate risk). Only 9.8% followed the right modality of antibiotic prophylaxis prescription; 4.9% of the dentists prescribed antibiotic only 1 hour before the act and 4.9% of them prescribed antibiotic 1 hour before the act and continued the treatment in case of the presence of an infectious site.

Conclusion

A discrepancy towards an over-estimation of risk and overprescription of antibiotic was found between the recommendations and real practice. Similar studies in the other governorates of Tunisia are recommended in order to better understand the problem.

Audit and feedback with or without training in-practice targeting antibiotic prescribing (TiPTAP): a study protocol of a cluster randomised trial in dental primary care

BACKGROUND

Antimicrobial resistance is an increasingly serious threat to global public health and patient safety. Overuse of antibiotics has aggravated this issue. Around 7% of all antibiotics in Scotland are prescribed by dentists. Audit and feedback has been shown to decrease these prescriptions, but there is evidence that dentists still prescribe unnecessarily. Our aim is to compare the effectiveness of a theory-informed in-practice training session (TiPTAP) in addition to individualised audit and feedback, with audit and feedback alone for reducing antibiotic prescribing by NHS dentists working in NHS primary care dental practices.

METHODS

We will conduct a 2-arm parallel cluster randomised trial: out of 228 practices, 114 will be randomised to the theory-informed in-practice training session targeting antibiotic prescribing and individualised audit and feedback; 114 practices will be randomised to audit and feedback alone. The theory-informed session will include (a) an introductory session including several behaviour change techniques; (b) problem solving discussion, setting and recording action plans; (c) practice-level prescribing feedback discussion. The primary outcome is the number of antibiotic items per 100 NHS treatment claims over a 1-year period post-randomisation for each dentist. Secondary outcomes are the number of amoxicillin 3 g and broad spectrum antibiotics prescribed per 100 NHS treatment claims over a 1-year period; amoxicillin 3 g and broad spectrum antibiotics defined daily doses of antibiotics per 100 claims. Process measures include fidelity, knowledge, and confidence. Primary and secondary outcomes will be obtained using routine data.

DISCUSSION

This study provides the opportunity to robustly assess the effect of adding an in-practice training co-intervention to audit and feedback. Its behaviour change theory-informed content will allow replication of the different components and can inform future training interventions.

Implications of COVID-19 Pandemic on the Emergence of Antimicrobial Resistance: Adjusting the Response to Future Outbreaks

The net effect of the coronavirus disease 2019 (COVID-19) pandemic and the response to it on the emergence of antimicrobial resistance is yet unknown. Positive impacts on the spread of multiresistant pathogens and infections in general may be observed with the implementation of general preventative measures for the spread of infectious disease such as social distancing, reduced travel and increased personal hygiene. This pandemic has accelerated the development of novel technologies, such as mRNA vaccines, that may be used to fight other diseases. These should be capitalized upon to manage the ongoing antimicrobial resistance pandemic in the background. However, it is likely that the COVID-19 pandemic is fueling the emergence of antimicrobial resistance due to high rates of inappropriate antimicrobial prescribing, the high use of biocides and the interruption of treatment for other conditions. Clinical uncertainty driven by the lack of effective diagnostics and practice of telemedicine may have driven the inappropriate use of antimicrobials. As pathogens know no borders, increased focus is needed for infectious diseases still threatening low- and middle-income countries such as tuberculosis. Stewardship measures for future outbreaks should stress the importance of social distancing and hand washing but discourage the overuse of disinfectants and antimicrobials that are not proven effective.

The effect of SARS-CoV-2 on the prescribing of antimicrobials and analgesics by NHS general dental practitioners in England

Aims To ascertain the effect of SARS-CoV-2 on the utilisation of antibacterial agents and analgesics in primary dental care.Methods Antibacterial agents and analgesics (eg paracetamol, aspirin) prescribed in England by general dental practitioners for the periods April-July 2019 and April-July 2020 were analysed.Results Antibacterial agents prescribed during COVID-19 restrictions in 2020 (799,282) were higher than a similar time period in 2019 (654,332) by 22%. Amoxicillin was used the most (2020 = 65.0%; 2019 = 66.3%) followed by metronidazole (2020 = 30.2%; 2019 = 28.7%). Erythromycin was prescribed at a similar rate, with lincosamides (clindamycin) prescribed more frequently in 2020 (2020 = 0.6%; 2019 = 0.5%). Clarithromycin was prescribed twice more often in 2020 (0.6%) in comparison to 2019 (0.3%). Co-amoxiclav (0.5%) and phenoxymethylpenicillin (0.3%) were prescribed at a similar rate. Analgesics use increased by 84% (2020 = 28,563; 2019 = 15,507). Use of dihydrocodeine tartrate increased (2020 = 40.9%; 2019 = 32.9%), followed by diclofenac sodium (2020 = 24.6%; 2019 = 12.8%). The opposite trend was seen in relation to ibuprofen with use decreasing (2020 = 19.4%; 2019 = 39.8%) while paracetamol use only slightly increasing (2020 = 15.1%; 2019 = 14.6%).Conclusions COVID-19 restrictions on dental care in England resulted in a marked increase in prescribing antibacterial agents and a very marked increase in prescription-only analgesics.
