Factors associated with the use of rapid antigen diagnostic tests in children presenting with acute pharyngitis among French general practitioners

Knowledge-Based Attitudes of Medical Students in Antibiotic Therapy and Antibiotic Resistance. A Cross-Sectional Study

We aimed to evaluate the knowledge-based attitudes of antibiotics and antibiotic resistance among medical students of Medical University of Warsaw using the questionnaire prepared by the study's authors. In May-June 2018, we carried out a cross-sectional study among the students of all years, embracing 291 respondents. The students were divided into two groups: A (students in their first to third years) and B (students in their fourth to sixth years). Our study has shown that students are aware of the dangers of antibiotic resistance, seeing the leading cause as antibiotic misuse. We have shown that they are also aware of their insufficient knowledge and believe that more antibiotic therapy classes should be included in the curriculum of Medical University of Warsaw. Our questionnaire also focused on attitudes towards antibiotics based on knowledge. One in four respondents (23.7%), based on their knowledge, negated antibiotic therapy ordered by a doctor in the event of their illness, and four in ten (40.9%) in the occurrence of disease of a family member or friend. The vast majority of students (92.4%) would like to broaden their knowledge on antibiotic therapy. However, only one-fifth of students have heard about the European Antibiotic Awareness Day campaign. We recommend increasing the number of hours on antibiotic therapy and resistance education combined with topics on hand hygiene.

Low Uptake of Rapid Diagnostic Tests for Respiratory Tract Infections in an Urban Safety Net Hospital

Background

Rapid diagnostic tests (RDTs) have been developed with the aim of providing accurate results in a timely manner. Despite this, studies report that provider uptake remains low.

Methods

We conducted a retrospective analysis of ambulatory, urgent care, and emergency department (ED) encounters at an urban safety net hospital with a primary diagnosis of an upper or lower respiratory tract infection (eg, bronchitis, pharyngitis, acute sinusitis) from January 1, 2016, to December 31, 2018. We collected RDT type and results, antibiotics prescribed, demographic and clinical patient information, and provider demographics.

Results

RDT use was low; a test was performed at 29.5% of the 33494 visits. The RDT most often ordered was the rapid Group A Streptococcus (GAS) test (n = 7352), predominantly for visits with a discharge diagnosis of pharyngitis (n = 5818). Though antibiotic prescription was more likely if the test was positive (relative risk [RR], 1.68; 95% confidence interval [CI], 1.58–1.8), 92.46% of streptococcal pharyngitis cases with a negative test were prescribed an antibiotic. The Comprehensive Respiratory Panel (CRP) was ordered in 2498 visits; influenza was the most commonly detected pathogen. Physicians in the ED were most likely to order a CRP. Antibiotic prescription was lower if the CRP was not ordered compared with a negative CRP result (RR, 0.77; 95% CI, 0.7–0.84). There was no difference in prescribing by CRP result (negative vs positive).

Conclusions

RDTs are used infrequently in the outpatient setting, and impact on prescribing was inconsistent. Further work is needed to determine barriers to RDT use and to address potential solutions.

Association between rapid antigen detection tests and antibiotics for acute pharyngitis in Japan: A retrospective observational study

The application and clinical impact of rapid antigen detection test (RADT) in the treatment of acute pharyngitis is unknown in Japan. We aimed to examine the proportions of RADT usage to identify Group A β-hemolytic Streptococcus (GAS) in outpatients with acute pharyngitis and evaluate the association between RADT and antibiotic treatment. We analyzed health insurance claims data from 2013 to 2015. Logistic regression models were used to analyze associated factors with RADT, overall antibiotic prescription, or penicillin use. We analyzed 1.27 million outpatient visits with acute pharyngitis, in which antibiotics were prescribed in 59.3% of visits. Of the total visits, 5.6% of patients received RADT, and 10.8% of the antibiotics were penicillin. Penicillin selection rates were higher in cases with RADT (25.4%) than those without RADT (9.7%). Compared to large-scale facilities, antibiotic prescription rates were higher in physicians' offices. For factor analysis, age (3-15 years), diagnosis code (streptococcal pharyngitis), size of the medical facility (large-scale hospitals), and physician's specialty (pediatrics) were associated with RADT use. Penicillin selection rate increased with RADT implementation (25.4% vs. 9.7%: adjusted odds ratio 1.55; 95% CI, 1.50-1.60). At 63% of the facilities, the RADT implementation rate was <5% of acute pharyngitis visits prescribed antibiotics. In conclusion, the proportion of RADT usage for outpatients with acute pharyngitis was low in Japan. With appropriate indication and evaluation, we expect that more utilization of RADT can help promote antimicrobial stewardship for outpatients with acute pharyngitis by prompting penicillin therapy. Further investigation with detailed clinical data are warranted.

Rapid antigen test use for the management of group A streptococcal pharyngitis in community pharmacies

Despite group A streptococci being an infrequent cause of pharyngitis in adult outpatients, sore throat remains a common indication for antibiotic prescription. This prospective multicentre non-randomised study describes a community pharmacy-based antimicrobial stewardship intervention consisting in the implementation of rapid antigen testing (RAT) for the management of adults with sore throat. Trained pharmacists triaged patients presenting with symptoms of pharyngitis using the modified Centor score. Those at risk for streptococcal infection were tested with RAT. Patients with a positive RAT were invited to consult a physician, whereas others were offered a symptomatic treatment. All patients received educational leaflets and were asked to fill in a follow-up form 7 days later. Ninety-eight pharmacies in one French region participated, and 559 patients were included over 6 months. RAT was proposed in 367 (65.7%) cases, and it was positive in 28 (8.3%). The follow-up form was returned by 140 (38.5%) participants. Of these, 10/10 patients with positive RAT further consulted a physician and were prescribed an antibiotic treatment, whereas 96.5% (110/114) of patients with negative results and not having any other reason to seek for doctor's advice did not consult. All participants found the intervention useful. Pharmacists spent 6-15 min to perform the intervention, and 98.6% (73/74) of pharmacists giving a feedback declared to be ready to implement this intervention in daily practice, if endorsed and reimbursed. Our results suggest that a pharmacy-based programme for the management of sore throat is feasible and could increase adherence to guidelines.

General practitioners and vaccination of children presenting with a benign infection

PURPOSE

To assess the self-reported vaccination behavior of general practitioners (GPs) when asked whether they would recommend the vaccination of a child presenting with a febrile uncomplicated common cold.

METHODS

We performed a cross-sectional survey in 2014 on a national sample of GPs. GPs were randomly assigned to one of eight clinical vignettes, all describing a child presenting with an uncomplicated febrile common cold, but differing by age (4 or 11 months), temperature (38°C or 39°C), and the mother's emotional state (calm or worried). GPs were asked whether they would recommend immediate vaccination of the child with a hexavalent vaccine (diphtheria, tetanus, pertussis, poliomyelitis, Haemophilus influenzae type b, and hepatitis B), or postpone it. We investigated the relation between the GPs' recommendation to vaccinate, the clinical vignette's variables, and the GPs' perceptions, attitudes, and practices toward vaccination in a multivariate model.

RESULTS

Among the 1582 participating GPs, 6% recommended immediate vaccination. This behavior was more frequent with a temperature of 38°C rather than 39°C (10% vs. 3%, P<0.001). GPs who felt comfortable giving explanations about vaccine safety were more likely to recommend immediate vaccination of the febrile child (P=0.045), but none of the other GPs' characteristics were associated with their vaccination behavior.

CONCLUSIONS

Almost all GPs postponed the hexavalent vaccination of the febrile child presenting with an uncomplicated viral disease; fever being the major factor affecting their decision. More research is needed on vaccination responses in sick children, as well as clearer guidelines.

Polish Physicians’ Attitudes Towards Antibiotic Prescription and Antimicrobial Resistance

Antimicrobial resistance has been one of the biggest global current issues in medicine and public health. Overuse and imprudent use of antimicrobial agents are recognized as one of the leading causes of antibiotic resistance. The aim of this study was to analyze the attitudes of Polish physicians practicing at the community level towards antibiotics and antimicrobial resistance. The majority of physicians taking part in the survey believed that Polish people overuse antibiotics (98%). Most physicians (91%) considered that antimicrobial resistance is a major problem at present. The majority of physicians indicated the reasons for prescribing the antibiotic are related to health factors, such as optimal recovery (best effectiveness, least side effects) (80%), latest therapeutic guidelines (70%) and microbiological/epidemiological factors (63%). Knowledge of the National Recommendations for the management of Community-Acquired Respiratory Tract Infections 2010 (NR-CA-RTI) developed within National Programme for Protection of Antibiotics was declared by 84% of respondents. Among those who are aware of the NR-CA-RTI, the majority follow them in their daily practice (91%). Among physicians, 62% are not familiar with the Centor/McIsaac scores used to differentiate bacterial and viral infections in patients presenting with a sore throat. Among physicians familiar with the scores, 90% use them in their daily practice. Rapid microbiological detection methods for Group A beta-hemolytic streptococcal pharyngitis are used only by 20% of respondents. Almost all of physicians declared readiness to use these tests. Main sources of information on antibiotics prescribing originate from Polish medical journals, scientific conferences organized by medical societies, pharmaceutical companies.

Peritonsillar abscess (PTA): clinical characteristics, microbiology, drug exposures and outcomes of a large multicenter cohort survey of 412 patients hospitalized in 13 French university hospitals

The aim of this study was to describe the epidemiology of hospitalized patients with peritonsillar abscess (PTA). We conducted a multicenter survey in 13 French university hospitals in 2009-2012 describing 412 patients. Median age was 29 year (range, 2-84) and current smoking habit was reported by 177 (43 %) patients. Most of the patients (92 %) had consulted a physician for sore throat within 10 days before admission for PTA diagnosis. Additional symptoms such as visible tonsil abnormalities (83 %), tender cervical adenopathy (57 %) and fever ≥ 38.5 °C (53 %) were also reported. A total of 65 % patients (269/412) reported recent systemic anti-inflammatory agents (AIAs) exposure by medical prescription (70 %), self-medication (22 %), or both (8 %); 61 % and 27 % reported recent exposure to antibiotic and topical treatments for sore throat, respectively. Non-steroidal AIAs were used most often (45 %), particularly arylpropionic derivatives. A rapid diagnosis antigen test (RDT) for Streptococcus pyogenes was performed in 70 (17 %) patients and was positive in 17 (24 %), of whom 9 (53 %) were exposed to AIAs and 14 (82 %) to antibiotics. To treat PTA, antibiotic therapy was given to 392 (95 %) patients. Of 333 antibiotic prescriptions, amoxicillin-clavulanic acid and metronidazole were the most prescribed antibiotics (42 and 17 %, respectively). Surgical drainage of the abscess was performed in 119 (29 %) cases and tonsillectomy in 75 (18 %) cases. The clinical outcome was favorable during the hospital stay in 404 (98 %) patients. In conclusion, patients with sore throat are often exposed to AIAs before PTA diagnosis, and antibiotic prescription was not often based on the RDT positivity.

How can we improve antibiotic prescribing in primary care?

Antibiotic stewardship is a necessity given the worldwide antimicrobial resistance crisis. Outpatient antibiotic use represents around 90% of total antibiotic use, with more than half of these prescriptions being either unnecessary or inappropriate. Efforts to improve antibiotic prescribing need to incorporate two complementary strategies: changing healthcare professionals' behaviour, and modifying the healthcare system. In this review, we present a broad perspective on antibiotic stewardship in primary care in high and high-middle income country settings, focussing on studies published in the last five years. We present the limitations of available literature, discuss perspectives, and provide suggestions for where future work should be concentrated.

Design of a national and regional survey among French general practitioners and method of the first wave of survey dedicated to vaccination

OBJECTIVES

France is currently facing a vaccine-hesitancy crisis. We conducted a questionnaire-based telephone interview with a large sample of general practitioners (GPs) as they play a crucial role in the vaccination process. Our main objectives were to study the GPs' vaccination behaviors when it comes to their own vaccination and that of their relatives, and the vaccine recommendations made to their patients. We also aimed to understand their opinion related to the severity of vaccine-preventable diseases and to assess their trust in various sources of information. Finally, we enquired about their opinion in terms of vaccination-related tools that could help them in their daily practice. The article aimed to present the design of this panel and survey.

PATIENTS AND METHODS

Four samples of GPs (one national and three regional) were selected among all the French GPs (metropolitan France) using random sampling. Five cross-sectional surveys should be conducted with that panel. The mean targeted sample size is 2350 GPs for each survey. The survey dedicated to vaccination was conducted by telephone or on the Internet.

RESULTS

GPs were included in the survey between December 2013 and February 2014. The national sample included 1582 GPs (response rate: 46%) and the three regional samples included 1297 GPs (response rate: 44%). The survey dedicated to vaccination was conducted between April and July 2014; the national sample response rate was 92% (1582/1712).

CONCLUSION

The results of the first wave of surveys, conducted on a large sample of French GPs, provide important information to guide the French vaccination policy.

[Prospective cross-sectional study of antibiotic prescriptions in a sample of French general practitioners]

OBJECTIVES

The aim of our study was to assess the quality of antibiotic prescriptions in a sample of general practitioners (GPs) receiving junior doctors in training, whatever the motive of the prescription.

METHODS

We performed a prospective observational study of all antibiotics prescribed in October 2012 by 21 GPs working in southeastern France. Two specialists (general medicine and infectious diseases) independently assessed the compliance with recommendations of antibiotic prescriptions using a validated algorithm.

RESULTS

Two hundred and thirty-two antibiotic courses were prescribed, mainly for low respiratory tract infections (30%), ENT (26%), urinary tract (22%) or skin (13%) infections. Forty prescriptions were considered as appropriate (17%), 77 as inappropriate (33%; mainly due to a non-recommended molecule choice [77%] or a too long treatment duration [44%]) and 115 prescriptions were unnecessary (50%), due to diagnostic issues. There were wide variations between GPs. An essential laboratory or imaging investigation was missing for 36% of prescriptions: chest X-ray for pneumonia (80% were missing), rapid antigen diagnostic test for acute pharyngitis (23% missing) and urine dipstick for urinary tract infections (80% missing). Fluoroquinolones and macrolides/synergistins accounted for 31% of the prescriptions, and were associated with a lower prevalence of appropriate prescriptions (7% and 2% respectively, P<0.001). There was a co-prescription of anti-inflammatory drugs in 15% of the cases.

CONCLUSION

The misuse of antibiotics was frequent in this study. Improving the diagnostic workout is of paramount importance. Urgent actions are needed to improve antibiotic use in general practice.
