A Multicultural Demographic Study to Analyze Antibiotic Prescription Practices and the Need for Continuing Education in Dentistry

Antibiotics Prescribing Pattern and Quality of Prescribing in Croatian Dental Practices-5-Year National Study

PURPOSE

Antibiotic resistance is one of the biggest threats to global health today. The aim of this study was to analyze antibiotic prescribing patterns and quality of prescribing in Croatian dental practices over a 5-year period.

METHODS

This is a retrospective observational study based on the analysis of the electronic prescriptions (medicines in ATC groups J01 and P01) from dental practices in Croatia prescribed from 1 January 2015 to 31 December 2019. Prescriptions were retrieved from the Croatian Health Insurance Fund (HZZO). The analyses included the number of prescriptions, type and quantity of prescribed drugs, indication, and the patient's and prescriber's characteristics.

RESULTS

The consumption increased from 1.98 DID in 2015, to 2.10 DID in 2019. The most prescribed antibiotic was Amoxicillin with clavulanic acid followed by Amoxicillin, Clindamycin, Metronidazole and Cefalexin. The analyses showed that 29.79% of antibiotics were not prescribed in accordance with the contemporary guidelines for the proper use of antibiotics. Additionally, 22% of antibiotics were prescribed in inconclusive indications.

CONCLUSION

The research showed an increase in antibiotic consumption over five years along with unnecessary prescribing of antibiotics in cases with no indications for its use. The development of national guidelines for antibiotic use is necessary.

Antibiotic Prescribing in Dental Medicine-Best Practices for Successful Implementation

With rising rates of antimicrobial resistance throughout the world, it is time to revisit antibiotic prescribing policies and practices, and dentistry is an important area for focused intervention, as it accounts for up to 15% of all antimicrobial prescriptions. In this narrative review, we have analyzed the current state of the knowledge, attitudes, and practice regarding antimicrobial use among dental professionals, and we have identified a set of seven recurring themes that drive inappropriate antibiotic prescribing in dental medicine. These include: 1. Prescribing antibiotics to delay or avoid dental treatment. 2. Overlooking the 5Ds-dental treatment (source control), dental condition (indication), drug (antibiotic choice), dose, and duration. 3. Relying on education from the distant past and on previous experience. 4. The heterogeneity of (too many) guideline recommendations leads to confusion and over-prescribing. 5. Decreased access to guideline information in private practice. 6. Psychological factors such as pressure to prescribe, comfort prescribing and the weekend effect, and 7. Feeling removed from antimicrobial resistance and externalizing responsibility. Based on the existing knowledge, we propose a framework based on four key pillars for focused intervention: 1. Education. 2. Internalizing responsibility. 3. Recognizing recurring counter-productive practices, and 4. Addressing recurring counter-productive practices. This framework can be applied in different dental settings to ensure best practices for the successful implementation of rational antimicrobial prescribing.

Systemic Antibiotic Use in Acute Irreversible Pulpitis: Evaluating Clinical Practices and Molecular Insights

This scoping review systematically evaluates the use of systemic antibiotics in treating acute irreversible pulpitis, integrating clinical practice patterns with recent molecular insights. We analyzed clinical evidence on antibiotic prescription trends among dental professionals and examined molecular research advancements in relation to pulpitis. This review is intended to bridge the gap between clinical practice and molecular research, guiding more evidence-based approaches to treating acute irreversible pulpitis. Electronic databases were searched for relevant articles published in English based on the objective of the review. A second search using all identified keywords and index terms was undertaken across all the included databases. In addition, a reference list of identified articles was searched. Studies including original research, systematic reviews, meta-analyses, clinical trials, and observational and retrospective studies, all written in English and published from 2010 onwards, were included, and an analysis of the text words contained in the titles and abstracts of the retrieved papers and of the index terms used to describe the articles was performed. A total of N = 53 articles were selected. Altogether, N = 43 (76.79%) articles were cross-sectional studies, N = 4 (11.11%) were systematic reviews, and N = 3 (5.36%) were guidelines. The most frequent level of evidence was level VI (N = 43 (76.79%). The mean percentage of dentists who prescribed antibiotics to treat acute irreversible pulpitis was 23.89 ± 23.74% (range: 0.05-75.7). Similarly, for specialists, it was 22.41 ± 15.64 (range 2.2-50.4), and the percentage for undergraduates was 17.52 ± 20.59 (range 0-62.6). The significant developments in research models for pulpitis research and the characterisation of biomarkers have led to better management strategies. Concurrently, significant advancements in molecular research provide new understandings of pulpitis, suggesting alternative therapeutic approaches. Although there are guidelines available, increased rates of antibiotic prescription are still prevalent around the globe.

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.

Bacterial resistance to antiseptics used in dentistry: A systematic scoping review of randomized clinical trials

OBJECTIVES

To evaluate the prevalence and proportions of bacteria resistant to antiseptics used in dentistry.

METHODS

A review of randomized clinical trials (RCTs) was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for scoping reviews involving different databases. MeSH terms and keywords were provided to examine only RCTs with antiseptic-resistant results.

RESULTS

Five RCTs were included. These investigations analysed 442 patients. Concerning the prevalence and proportion of species resistant to antiseptics, it was found that the chlorhexidine group showed a statistically significant increase in Streptococcus mutans and Lactobacillus acidophilus counts indicating bacterial resistance (p < 0.001). Moreover, Veillonella species showed resistance to triclosan at the commencement and during the RCTs, and a slight increase in the proportion of resistant strains was observed. Porphyromonas gingivalis, Staphylococcus aureus, and Pseudomonas aeruginosa did not show resistance to cetylpyridinium chloride. Similarly, it was no observed resistance to medicinal herbal plant formulations.

CONCLUSIONS

Resistance of S. mutans and L. acidophilus to chlorhexidine was observed, this resistance increased during the follow-up period. Similarly, although in a slight proportion, an increase in the resistance of Veillonella spp. to triclosan during the study period was also described. No microorganisms resistance was observed to any of the other antiseptics studied.

Study of the Drivers of Inappropriate Use of Antibiotics in Community Pharmacy: Request for Antibiotics Without a Prescription, Degree of Adherence to Treatment and Correct Recycling of Leftover Treatment

INTRODUCTION

The WHO considered antibiotic resistance as 1 of the 10 greatest threats to global health in 2019. The inappropriate and indiscriminate use of antibiotics, together with the lack of new therapeutic alternatives, may eradicate their effectiveness in the closest future.

OBJECTIVE

The general objective is to analyze the different causes attributable to patients, providers and pharmacists that could be drivers of irrational use of antibiotics, and responsible for the appearance of bacterial resistance, in community pharmacies. To this end, the different processes or indicators were studied: patients' requests of antibiotics at the pharmacy, their degree of adherence, satisfaction with the prescribed treatment and antibiotics' surplus recycling.

METHODS

This study was observational, descriptive, and cross-sectional, carried out in 2 pharmacy offices, including 333 participants. At the time of dispensing, first phase, surveys to collect patients', providers' and pharmacists' data were carried out over the counter. The second phase, with the aim of checking adherence, degree of satisfaction and recycling.

RESULTS

There were 333 requests for antibiotic regardless prescription availability, 17% of the patients requested an antibiotic without having one. 38% of patients did not have full adherence to antibiotics. Exploring non-adherence reasons, 24% forgot to take the treatment, 2% experienced adverse effects; 8% improved infection symptoms and 21% had problems to follow schedule. Regarding the recycling habits, 57% of patients had leftover treatments at home, but only 11% recycled it. 10% of medical prescriptions were forced by the patient, and significant gender differences were observed in adherence and knowledge of treatment.

CONCLUSION

The results of this study suggested that there may be a significant level of antibiotic inappropriate use locally, potentially related to patients' sex, finding significant deficiencies in prescription by doctors, in the dispensing act carried out in community pharmacies, and finally in patient compliance with treatment.

Antibiotic prescription after tooth extraction in adults: a retrospective cohort study in Austria

BACKGROUND

Broad spectrum antibiotics are often used for the prophylaxis of infectious endocarditis and treatment of odontogenic infections, but there are limited data related to antibiotic use and adherence to prescription guidelines.  METHODS: Data from patients with tooth extraction between 2014 and 2018 were selected from a database of a regional health insurance fund. We created three data sets, one based on all tooth extractions, one on multiple teeth extractions, and one including only single tooth extraction. After data collection, descriptive analysis was carried out. The differences in prescription pattern of antibiotic medicine were tested by χ² test, Student´s t-test or ANOVA.

RESULTS

From 43,863 patients with tooth extraction, 53% were female, and 3,983 patients (9.1%) filled a prescription for antibiotic medicine. From 43,863 patients, 157 patients (0.4%) had endocarditis risk, but only 8 patients of these (5.1%) filled an antibiotic prescription. In total, 9,234 patients had multiple and 34,437 patients had only one tooth extraction. Patients with more than one tooth extraction received more often antibiotic treatment (10.7%) compared to those with single tooth extractions (χ² = 36; p < 0,001). Patients with more than one tooth extraction were older, however, younger patients received antibiotics more frequently (t = 28,774, p = 0.001). There was no relationship with endocarditis risk status. Clindamycin and amoxicillin/clavulanic acid were the most frequently prescribed antibiotic medicines.

CONCLUSIONS

In this retrospective cohort study, dentists did not discriminate prophylactic antibiotic prescription with regard to endocarditis risk status. A factor influencing prescribing behaviour of antibiotic medicines was the number of extracted teeth.

Microbial resistance to oral antiseptics used in hospitalized patients: A systematic scoping review of randomized clinical trials

AIMS

To evaluate the prevalence and proportions of bacteria resistant to oral antiseptics used in hospitalized patients.

METHODS AND RESULTS

A review of randomized clinical trials (RCTs) was led by implementing the PRISMA extension for scoping reviews including various databases. MeSH terms and keywords were used to assess only RCTs with antiseptic-resistant outcomes. Fourth RCTs met the selection criteria. These trials studied 399 hospitalized patients for respiratory infections or cardiovascular disease. Methicillin-resistant Staphylococcus aureus and Acinetobacter baumannii were predominant pathogens in the chlorhexidine group. It was found that Veillonella parvula and Campylobacter gracilis (57% of the isolates) had resistance to triclosan, while 67% of Pseudomonas, Acinetobacter, and Enterobacter species presented resistance to chlorhexidine. However, an increase in minimal inhibitory concentrations of triclosan or chlorhexidine during the follow-up period was not observed. Moreover, chlorhexidine reduced the amount of S. aureus in dental plaque and the oropharyngeal colonization by aerobic microorganisms; nonetheless, it was unsatisfactory to decrease the occurrence of respiratory infections. No adverse events were reported.

CONCLUSIONS

Resistance of V. parvula and C. gracilis to triclosan, and Pseudomonas, Acinetobacter, and Enterobacter species to chlorhexidine were perceived. However, these resistances did not increase during the follow-up period.

Polish Medical Doctors’ Opinions on Available Resources and Information Campaigns concerning Antibiotics and Antibiotic Resistance, a Cross-Sectional Study

Background: Antibiotic resistance (ABR) is at the top of global health threats. This paper aims to assess Polish physicians’ readiness to impact ABR through prescribing routines. Methods: Surveying Polish physicians participating in specialization courses at the Center for Postgraduate Medical Education in Warsaw, Poland from October 2019 to March 2020. Results: Information was obtained from 504 physicians aged 25–59, mean 32.8 ± 5.9 years, mainly women (65%). Most doctors (78%) prescribed antibiotics at least once a week. Physicians indicated clinical practice guidelines as resources most often consulted in the management of infections (90%). However, clinical experience was also declared a powerful resource. In total, 54% of respondents recalled receiving information about the prudent use of antibiotics within 12 months, which partially translated into changing views (56%) and practice (42%). Physicians disagreed that national campaigns provide good promotion of prudent antibiotics use (75%) or that they are effective (61%). Only 40% of doctors were aware of the national campaign promoting responsible antibiotics use, 24% had heard about the European Antibiotic Awareness Day and 20% knew about the World Antimicrobial Awareness Week. Conclusions: Prescribers most often rely on clinical practice guidelines and their own experience as resources for antibiotics use. Doctors’ awareness of available resources and information campaigns concerning antibiotics and antibiotic resistance should be improved.

Comparative Efficacy of Different Oral Doses of Clindamycin in Preventing Post-Operative Sequelae of Lower Third Molar Surgery—A Randomized, Triple-Blind Study

Background and Objectives. Antibiotic regimen optimization is a major concern in post extraction sequelae management following third molar surgery, mostly owing to the absence of universal guidelines. Hence, this study aimed to determine the effect of antibiotic prophylaxis using three different doses of clindamycin on the prevention of infection and other complications following mandibular third molar disimpaction. The secondary outcome was testing whether clindamycin exhibits activity in acute or chronic models of pain using the visual analog scale of pain and the necessity for post-operative rescue analgesia. The tertiary outcome was to assess clindamycin penetration into the saliva by measuring its concentration using liquid chromatography/electrospray ionization tandem mass spectrometry. Materials and Methods. A randomized, two-center, triple-blind, controlled clinical trial was conducted, in which the patients were randomly allocated to three groups: I, receiving 150 mg clindamycin every 8 h; II, receiving 300 mg clindamycin every 8 h; and III, receiving 600 mg clindamycin every 12 h. Each group continued the therapy for five days. Results. An overall decrease in the risk of infection and other post-operative complications, such as trismus, edema, dysphagia, and lymphadenopathy, was achieved, with the best results in group I. Conclusion. As no statistical association was observed between clindamycin concentration in saliva and degree of post-operative inflammation, clindamycin concentration, or pain intensity, smaller doses of clindamycin administered over shorter time periods is recommended.

Introduction of Probiotic-Based Sanitation in the Emergency Ward of a Children’s Hospital During the COVID-19 Pandemic

Background

Antimicrobial resistance (AMR) represents a major threat to public health, especially in the hospital environment, and the massive use of disinfectants to prevent COVID-19 transmission might intensify this risk, possibly leading to future AMR pandemics. However, the control of microbial contamination is crucial in hospitals, since hospital microbiomes can cause healthcare-associated infections (HAIs), which are particularly frequent and severe in pediatric wards due to children having high susceptibility.

Aim

We have previously reported that probiotic-based sanitation (PCHS) could stably decrease pathogens and their AMR in the hospital environment, reduce associated HAIs in adult hospitals, and inactivate enveloped viruses. Here, we aimed to test the effect of PCHS in the emergency room (ER) of a children’s hospital during the COVID-19 pandemic.

Methods

Conventional chemical disinfection was replaced by PCHS for 2 months during routine ER sanitation; the level of environmental bioburden was characterized before and at 2, 4, and 9 weeks after the introduction of PCHS. Microbial contamination was monitored simultaneously by conventional culture-based CFU count and molecular assays, including 16S rRNA NGS for bacteriome characterization and microarrays for the assessment of the resistome of the contaminating population. The presence of SARS-CoV-2 was also monitored by PCR.

Results and conclusions

PCHS usage was associated with a stable 80% decrease in surface pathogens compared to levels detected for chemical disinfection (P < 0.01), accompanied by an up to 2 log decrease in resistance genes (Pc < 0.01). The effects were reversed when reintroducing chemical disinfection, which counteracted the action of the PCHS. SARS-CoV-2 was not detectable in both the pre-PCHS and PCHS periods. As the control of microbial contamination is a major issue, especially during pandemic emergencies, collected data suggest that PCHS may be successfully used to control virus spread without simultaneous worsening of the AMR concern.
