Antibiotic misuse: a prospective clinical audit in a French university hospital

Evaluation of a host-protein signature score for differentiating between bacterial and viral infections: real-life evidence from a German tertiary hospital

PURPOSE

A host-protein signature score, consisting of serum-concentrations of C-reactive protein, tumour necrosis factor-related apoptosis-inducing ligand, and interferon gamma-induced protein 10, was validated for distinguishing between bacterial and viral infections as an antimicrobial stewardship measure for routine clinical practice among adult patients in a German tertiary hospital.

METHODS

This single-centre, explorative study prospectively assessed the host-protein signature score, comparing it with serum procalcitonin (PCT) in patients with blood stream infections (BSI) and evaluating its efficacy in patients with viral infections against the standard of care (SOC) to assess the need for antibiotics due to suspected bacterial super/coinfection. Manufacturer-specified threshold scores were used to differentiate viral (< 35) and bacterial (> 65) infections.

RESULTS

Ninety-seven patients (BSI [n = 56]; viral infections [n = 41]) were included. The score (cut-off score > 65) tended to detect BSI with higher sensitivity than did PCT (cut-off > 0.5 ng/mL) (87.5% vs. 76.6%). Three patients (5.4%) with BSI had a score < 35. One patient with BSI did not receive antibiotic treatment following SOC prior to positive blood culture results. Among patients with viral infections, 29 (70.7%) had scores > 65, indicating bacterial superinfections. Additionally, 11 patients (26.8%) had scores < 35, indicating no bacterial superinfections. In total, the antibiotic treatment discrepancy in the viral group between the SOC and a host-protein signature score guided approach was 2/41 patients (4.9%).

CONCLUSION

The score tended towards a higher sensitivity in detecting BSI than that with PCT. However, its impact on reducing antibiotic use in viral infections was minor compared with that of SOC.

Knowledge, Perception, and Self-Confidence of Antibiotic Resistance, Appropriate Antibiotic Therapy, and Antibiotic Stewardship Among Undergraduate Pharmacy Students in Sudan

Background

Adequate training in infectious diseases and antibiotic resistance is crucial for pharmacy students to participate in antibiotic stewardship programs and understand microbiology careers.

Aim

The study was carried out to assess the knowledge and self-reported confidence in antibiotic resistance, antibiotic therapy, and antimicrobial stewardship (AMS) among final-year undergraduate pharmacy students in Sudan.

Methods

A cross-sectional study was conducted in three universities using a 57-item online questionnaire between April and May 2022.

Results

A total of 109 students (response rate 36%) participated and showed average knowledge scores of 5.6±1.7 (out of 10.0) for antibiotic resistance, 4.9±2.0 (out of 5.0) for appropriate antibiotic therapy, and 3.1±1.4 (out of 5.0) for AMS. No significant differences were observed among schools. Some students reported poor knowledge about antibiotic therapy and the consequences of resistance. One-third of students lacked confidence in interpreting microbiological results. Knowledge of antibiotic resistance among students' practice area after graduation was higher (p=0.017) and those interested in ID careers (5.8 vs 4.8) (p=0.037). Male students (5.6 vs 4.5) and those interested in ID careers (4.3 vs 3.4) (p<0.001) had higher scores of appropriate antibiotic therapy. Students attended antibiotic resistance courses (51.5 vs 45.2), and those interested in ID significantly had higher self-confidence (55.3 vs 45.8) (p=0.008).

Conclusion

Pharmacy students in Sudan have substantial knowledge of AMS and antibiotic resistance with poor knowledge of antibiotic therapy. Adequate training about infectious diseases and related topics is recommended to improve pharmacy students' understanding of microbiological findings, other competencies, and skills to incorporate in antimicrobial stewardship.

Diagnostic uncertainty in infectious diseases: Advocacy for a nosological framework

Diagnostic uncertainty (DU) is frequent in infectious diseases (ID), being recorded in 10% to over 50% of patients. Herein, we show that in several fields of clinical practice, high rates of DU are constant over time. DUs are not taken into account in guidelines, as therapeutic propositions are based on an established diagnosis. Moreover, while other guidelines underline the need for rapid broad-spectrum antibiotic therapy for patients with sepsis, many clinical conditions mimic sepsis and lead to unnecessary antibiotic therapy. Considering DU, many studies have been carried out to look for relevant biomarkers of infections, which also attest to non-infectious diseases mimicking infections. Therefore, diagnosis is often primarily a hypothesis, and empirical antibiotic therapy should be reassessed when microbiological data are available. However, other than for urinary tract infections or unexpected primary bacteremia, the high frequency of sterile microbiological samples implies that DU remains central in follow-up, which does not facilitate clinical management or antibiotic optimization. The main way to resolve the therapeutic challenge of DU could be to precisely describe the latter through a consensual definition that would facilitate consideration of DU and its mandatory therapeutic implications. A consensual definition of DU would also clarify responsibility and accountability for physicians in the antimicrobial approval process and l provide an opportunity to instruct their students in this large field of medical practices and to productively conduct relevant research.

Perceptions of community pharmacists regarding their role in antimicrobial stewardship in Pakistan: A way forward

BACKGROUND

Antimicrobial resistance is one of the biggest challenges to healthcare resulting in increased morbidity and mortality, and associated with drug resistant infections. Community pharmacists (CPs) can play a key role in antimicrobial stewardship (AMS) programs to aid the prudent use of antibiotics, and in infection prevention and control.

OBJECTIVE

The aim of this study was to assess perceptions of CPs regarding their role, awareness, collaboration, facilitators and barriers towards effective AMS practices in Pakistan.

METHOD

ology: A descriptive, cross-sectional study design was adopted, where convenience and snowball sampling methods were applied to enroll respondents (pharmacists working at these community pharmacies in different cities of Pakistan) of the study. After sample size determination, n = 386 CPs were enrolled. A pre-validated questionnaire was used regarding CPs roles and perceptions in association with AMS. Statistical analysis was performed using SPSS v. 21.

RESULTS

The results of the study reported that 57.3% (n = 221) of CPs had strong familiarity with term AMS. 52.1% (n = 201) of CPs agreed that they require adequate training to undertake activities in AMS programmes in their setting. The results of the study showed that 92.7% (n = 358) of the pharmacists thought real time feedback would be helpful. Significant association was observed in AMS awareness, approach, collaboration and barriers with regards to the respondents' gender, age groups and levels of experience in a community pharmacy.

CONCLUSIONS

The study concluded that CPs were aware of AMS programmes, their relevance and necessity of AMS in their everyday practice, but had inadequate training and resources to implement it in Pakistan.

Impact of Infectious Diseases training in the perception of antibiotic resistance and rational use of antibiotics among Spanish medical students - a cross-sectional study

BACKGROUND

Antibiotic resistance is one of the main public health problems worldwide. One key tool to optimize antibiotic prescription is medical training. The aim of this study is to compare the impact of training in infectious diseases on students' knowledge of the antibiotic resistance problem and the rational use of antibiotics.

METHODS

We performed a cross-sectional study in the medical school of the University of Navarra. We conducted an anonymous in situ survey of students in each year of training. Data were analyzed grouping the students as follows: GROUP 1: first three years of education, no training in Clinical Microbiology (CM) or in Infectious Diseases (ID); GROUP 2: fourth-year students, training in CM but not ID; GROUP 3: Fifth and sixth-year students who have completed the training in CM and ID. Chi-square test (or Fisher's exact test when appropriate) was performed to evaluate potential associations. Wilcoxon's test was used to compare the median correct answers between groups. We used Spearman's test for correlation between year of training and performance in questionnaire.

RESULTS

A total of 994 students respond to the survey, 80.4% of the eligible students. Almost all students who had completed infectious diseases training perceive antibiotic resistance as an important problem in comparison with students who had not completed the formation (99.5% in group 3 vs 94.5% in group 1, p = 0.02). Knowledge of antibiotic stewardship underwent a statistically significant change after training in infectious diseases (from 9.2% in group 1 to 52.2% in group 3, p < 0.001). In the training questions block we also found an increase in the average number of correct answers (21.4% in group 1 vs 44.7% in group 3, p < 0.001). When comparing the results of subgroups 3A and 3B we found a significant loss of knowledge as we moved away from training (49% vs 40.9%, p < 0.001).

CONCLUSIONS

The training of medical students is the key to improving both perception and knowledge of infectious diseases. However, we have an opportunity for educational improvement as far as infectious diseases are concerned, regarding both the acquisition of knowledge and its loss as time lapses after training.

A Multicentric Survey of Indian Medical Students about their Knowledge and Perception on Antimicrobial Stewardship

Antimicrobial stewardship (AMS) and appropriate infection prevention practices are essential to decrease the rising trend of antimicrobial resistance (AMR). Good antimicrobial prescribing habits formed early in the medical career can make a paradigm shift in combating the menace of AMR. Scarce data is available about the knowledge and perceptions of Indian undergraduates on AMS. This study was planned to analyse the knowledge, attitude and perceptions (KAP) of Indian medical undergraduates on rational antimicrobial prescribing, so that the lacunae in the training curriculum can be identified and addressed effectively. A cross-sectional questionnaire-based survey was carried out, on the pre-final and final year medical students (6th to 9th semester) from six medical colleges across different states of India. A scoring system was used to rate the knowledge, attitude and perceptions of the respondents as poor, average, or good. A total of 1505 students (83.61%) participated in the survey. Majority of the students (81.7%) from all medical colleges favoured more education on antimicrobials and to incorporate AMS in the undergraduate curriculum through integrated teaching. The results showed that overall, 70.9% students had a “good” score for knowledge on antimicrobial use, whereas only 55% scored “good” for being confident in rational antimicrobial prescribing. Surprisingly, only 56.5% correct responses for knowledge on selection of broad-spectrum antibiotics over narrow-spectrum antibiotics were recorded in our study. Most of the students (79.9%) were conscious that irrational prescribing can result to AMR. On the other hand, 54.9% students believed that the supply of new antimicrobials would take care of AMR eventually. 78.1% of our students believed that they were confident in making the right diagnosis of infection, whereas, 63.7% of respondents believed that they were not confident in identifying the clinical scenarios where antibiotics are not required. Significant association (p<0.05) was seen for both “good” knowledge and perception scores with the higher academic semesters reflecting more clinical exposure in later in course semesters. The study has highlighted the areas of clinical weakness and dilemma regarding prescription of antimicrobials. Efforts to address these issues on basic principles of antimicrobial stewardship, is critical for laying the foundation of successful AMS program and contributing in overcoming the antimicrobial resistance. The study recommends targeted training, articulating fine details of prescribing antimicrobials with real time case scenarios through a multi-disciplinary approach. The Indian undergraduate medical curriculum needs to incorporate early well-structured training on AMS by integrating pharmacology and microbiology teaching with the clinical subjects to ensure appropriate antibiotic prescribing practices by the future prescribers.

Knowledge, attitude, and practice of clinicians about antimicrobial stewardship and resistance among hospitals of Pakistan: a multicenter cross-sectional study

Considering that antimicrobial resistance (AMR) is a global challenge, there is a dire need to assess the knowledge, attitude, and practice (KAP) of clinicians in AMR endemic countries. The current multicenter, cross-sectional study aimed at highlighting gaps in antimicrobial (AM) stewardship and AMR among practicing doctors working in public tertiary care teaching hospitals of Lahore, Pakistan. A KAP survey, based on a self-administered questionnaire containing 45 questions, was distributed among 336 clinicians in 6 randomly selected hospitals. Overall, 92% of the clinicians considered AMR as a worldwide problem but only 66% disagreed that cold and flu symptoms require antibiotics. Moreover, around 68% of the doctors felt confident about their practice in AM but still, 96% felt the need to get more knowledge about AM drugs. The need for refresher courses on rational antibiotic use was expressed by 84% of the participants. The main contributing factors considered for AMR by the doctors included excessive AM usage in the medical profession (87.1%) and multiple antibiotics per prescription (76.4%). Pharmacologically, AM spectrum was accurately chosen by 1.4% for Ampicillin, 0.003% for Erythromycin and 0% for Levofloxacin. Clinically, more than 50% of the clinicians used miscellaneous AM for empirical therapy of respiratory tract infection and cholecystitis. The data was analyzed using Statistical Package for Social Sciences (SPSS) version 25. It is concluded that the knowledge of clinicians is relatively poor for AM spectrum and drugs of choice for certain infections. However, the clinicians are aware of their shortcomings and desire for improvement.

The De-marketing Strategies as a Vital Resolve of Antibiotics Misuse Dilemma

Developing resistance to the currently available antimicrobial agents, particularly anti-Bacterial, is a worrying issue that rises highly worldwide. Communities, health workers, and government officials around the world are joining in, calling for overuse and misuse of antibiotics to stop. The phrase “de-marketing” indicates a strategy that drives to organize the form and the level of the current and future demand; not only that, but rationalizes it by organizations (profit, non-profit organizations as well as governments) specified to discourage and minimize activities of organizations about selling, distribution, using, and advertising… etc. It is to conduct an investigation of the potential impact of de-marketing in both controlling and minimizing the antibiotic misusage in Jordan. The essential purpose of the current analysis research is to manifest the contribution of the general demarketing strategy in influencing the attitude of consumers towards rationalization of taking antibiotics through regular medications, which is under the supervision and recommendations of professional doctors. In this article, we focused on those secondary resources derived from the published literature. Besides, we relied on the output of 450 consumers’ interactions and responses to our 19 questions distributed as a survey with consideration to the general ethics. The model of our study was designed based on the preliminary information collected from exploration study. The insight statistical analysis confirmed a attitude towards rationalization of taking antibiotics without doctor supervision (off prescription) that properly will raise the issue of antibiotics misuse along with its severe and dangerous side effects which will have a possible reduction of the undesirable and toxic effects after misusing the drugs. Moreover, this strategy would have a positive impact in lowering eco-toxicity of antibiotics misuse to words non-target aquatic organisms; plants or sediment and soil-inhabiting organisms. In conclusion, The problem of antibiotic resistance can be minimized only by concerted efforts of all members of society for ensuring the continued efficiency of antibiotics, the demarketing strategy shows a promising approach which could be used by any interested parties working to develop policies, strategies, interventions or campaigns to reduce antibiotic resistance.

'It makes life so much easier'-experiences of users of the MicroGuide™ smartphone app for improving antibiotic prescribing behaviour in UK hospitals: an interview study

Objectives

To understand the impact on prescribing behaviour of an antimicrobial therapy guidelines smartphone app, in widespread use in hospitals in the UK.

Methods

Twenty-eight doctors and five nurse prescribers from four purposively selected hospitals in the UK participated in behavioural theory-informed semi-structured interviews about their experiences of using the MicroGuide™ smartphone app. Data were analysed using a thematic content analysis.

Results

Five themes emerged from the interview data: convenience and accessibility; validation of prescribing decisions; trust in app content; promotion of antimicrobial stewardship; and limitations and concerns. Participants appreciated the perceived convenience, accessibility and timesaving attributes of the app, potentially contributing to more prompt treatment of patients with time-critical illness. The interviewees also reported finding it reassuring to use the app to support decision-making and to validate existing knowledge. They trusted the app content authored by local experts and considered it to be evidence-based and up-to-date. This was believed to result in fewer telephone calls to the microbiology department for advice. Participants recognized the value of the app for supporting the goals of antimicrobial stewardship by promoting the responsible and proportionate use of antimicrobials. Finally, a number of limitations of the app were reported, including the risk of de-skilling trainees, cultural problems with using smartphones in clinical environments and software technical problems.

Conclusions

The MicroGuide app was valued as a means of addressing an unmet need for updated, concise, trustworthy specialist information in an accessible format at the bedside to support safe and effective antimicrobial prescribing.

An Educational Game Evening for Medical Residents: A Proof of Concept to Evaluate the Impact on Learning of the Use of Games

Insufficient knowledge of bacteria and antimicrobials leads to the emergence of multidrug-resistant-bacterium infections. Diversification of the teaching forms, such as the use of games, could be a solution. We organized an event around 3 games (Bacteria Game, KROBS, and Dawaa) to collect student feedback on the evening and assess their knowledge before and after the evening using multiple-choice questions. The preliminary results suggest a positive effect of this event, but due to the low number of participants, we see this report more as a proof of concept to assess the impact of games on the learning.

Educational resource for antimicrobial resistance and stewardship for dentistry programmes: a research protocol

INTRODUCTION

Antimicrobial resistance (AMR) is a global public and patient safety issue. With the high AMR risk, ensuring that the next generation of dentists that have optimal knowledge and confidence in the area of AMR is crucial. A systematic approach is vital to design an AMR content that is comprehensive and clinically relevant. The primary objective of this research study will be to implement a consensus-based approach to elucidate AMR content and curriculum priorities for professional dentistry programmes. This research aims to establish consensus along with eliciting opinion on appropriate AMR topics to be covered in the Bachelor of Dental Surgery syllabus.

METHODS AND ANALYSIS

A three-phase approach to validate content for curriculum guidelines on AMR will be adopted. First, literature review and content analysis were conducted to find out the available pertinent literature in dentistry programmes. A total of 23 potential literature have been chosen for inclusion within this study following literature review and analysis in phase 1. The materials found will be used to draft curriculum on antimicrobials for dentistry programmes. The next phase involves the validation of the drafted curriculum content by recruiting local and foreign experts via a survey questionnaire. Finally, Delphi technique will be conducted to obtain consensus on the important or controversial modifications to the revised curriculum.

ETHICS AND DISSEMINATION

An ethics application is currently under review with the Institute of Health Science Research Ethics Committee, Universiti Brunei Darussalam. All participants are required to provide a written consent form. Findings will be used to identify significant knowledge gaps on AMR aspect in a way that results in lasting change in clinical practice. Moreover, AMR content priorities related to dentistry clinical practice will be determined in order to develop need-based educational resource on microbes, hygiene and prudent antimicrobial use for dentistry programmes.

Knowledge, attitudes, and perceptions about antibiotic use and antimicrobial resistance among final year undergraduate medical and pharmacy students at three universities in East Africa

INTRODUCTION

Proper measures to combat antimicrobial resistance development and spread in Sub Saharan Africa are very crucial bearing in mind the projected burden of antimicrobial resistance which is expected to be increase by 2050. Training of medical doctor and pharmacy students in antimicrobial stewardship is vital to combat antimicrobial resistance. This study was designed to evaluate the knowledge, attitude, and perception of final year medical and pharmacy students on antimicrobial use and antimicrobial resistance at three universities in Uganda, Kenya, and Tanzania.

METHODOLOGY

A cross-sectional survey was carried out among final year undergraduate medical and pharmacy students at three universities in East Africa. A Self-administered questionnaire was developed which included dichotomous questions and questions using a 4-point Likert scale. The questions were based on knowledge and attitude about antibiotics, and preparedness to use antibiotics in clinical scenarios. Data were analyzed using STATA version 16 following the objective of the study.

RESULTS

Three hundred and twenty-eight final year students participated in the survey from MUK 75, MKU 75 and CUHAS 178. Slightly majority of participants were male 192(58.5%) and their median age was 25 [23 - 27] years. In general, 36.6% (120/328) of students had good overall total knowledge. More students at MUK had good knowledge compared to MKU, and CUHAS (72% vs, 40% vs. 20.2%; p<0.001). The mean scores for overall good total knowledge, general knowledge about antibiotics, knowledge about antibiotic resistance, and knowledge about antibiotic use in clinical scenarios were 58% (CI: 57%- 60%), 95% (CI: 94%- 97%), 54% (CI: 52% - 56%), and 46% (CI:44% - 48%) respectively. More pharmacy students compared to medical students had a good attitude and perception on antibiotic use (79.6% vs. 68.4%; p = 0.026). The students at CUHAS perceived being more prepared to use antibiotic in district hospitals compared to MKU and MUK (75.3% vs. 62.7% vs. 65.3%; p = 0.079). While two hundred and seventy (82.3%) students perceived knowing when to start antimicrobial therapy, 112 (34.2%) did not know how to select the appropriate antibiotic (p<0.0001), 97 (29.6%) did not know the antibiotic dose to give (p<0.0001), and 111 (33.8%) did not know when to switch form an intravenous antibiotic to oral regimen (p<0.0001).

CONCLUSION

Final year students have low scores in knowledge about antimicrobial resistance and antibiotic use in clinical scenarios. This has exposed gaps in practical training of students, while they may feel confident, are not fully prepared to prescribe antibiotics in a hospital setting. A multidisciplinary and practical approach involving medical schools across the East African region should be undertaken to train final year undergraduate students in antimicrobial resistance and antimicrobial stewardship programs. Antimicrobial resistance and antimicrobial stewardship courses should be introduced into the curriculum of final year medicine and pharmacy programs.

Point prevalence survey of antimicrobial use in three hospitals in North-Eastern Tanzania

Background

Antimicrobial resistance (AMR) is one of the most urgent global health threats with low-resource countries being disproportionately affected. Targeted interventions require insight in antibiotic prescription practices. A point prevalence survey (PPS) is a well-known tool to get insight in antibiotic dispensing practices in hospitals and identify areas for improvement. Here, we describe the results of a PPS performed in a tertiary, regional and district hospital in Kilimanjaro region in Tanzania.

Methods

A PPS was performed in the Kilimanjaro Christian Medical Centre (KCMC; tertiary hospital), Mawenzi (regional) and St. Joseph (district) hospital in November and December 2016. Antibiotic use in all patients admitted more than 24 h and those undergoing surgery was recorded. All clinical wards were included except the pediatrics. Data from a single ward were collected on the same day.

Results

A total of 399 patients were included in the PPS: 232 patients from KCMC, 94 from Mawenzi hospital and 73 patients from St. Joseph hospital. Overall prevalence of antibiotic use was 44.0%: 38% in KCMC, 59% in Mawenzi and 63% in St. Joseph. Ceftriaxone (n = 94, 29.8%), metronidazole (n = 79, 23.9%) and other antibiotics belonging to the penicillin class (n = 89, 28.3%) were most commonly prescribed. Antibiotics prescribed for surgical prophylaxis were continued for more than 3 days in 57% of cases.

Conclusion

Our study shows a rate of broad-spectrum antibiotic use in Tanzanian hospitals and prolonged surgical antibiotic prophylaxis being a common practice. PPS is an important tool to improve future antibiotic use in Tanzania hospitals.

Educational antimicrobial stewardship programs in medical schools: a scoping review protocol

OBJECTIVE

The objective of this scoping review is to identify the available evidence on antimicrobial stewardship programs for teaching medical students about rational antimicrobial use, including the content taught and the method of instruction used.

INTRODUCTION

Antibiotics are life-saving drugs and their discovery is one of the most important advances of the 20th century. They have transformed modern medicine by playing a critical role in the management of infectious diseases. However, the rapid development of resistance of pathogens to antibiotics is gradually affecting this initial success. Antimicrobial stewardship programs have been shown to reduce the burden of antimicrobial resistance in hospitals.

INCLUSION CRITERIA

This scoping review will consider papers conducted in medical school curricula to improve the prescribing of antimicrobial medication. Studies that include other health profession students, such as nursing, pharmacy, or dentistry students, will be excluded. Studies published in English from 1996 onwards will be included.

METHODS

Databases to be searched are PubMed, Wiley Online library, CINAHL Complete, Web of Knowledge, Scopus and Education Resources Information Center. Unpublished studies and gray literature will be included. Searching will follow a three-step process and will be conducted by two reviewers. Data will be extracted by two independent reviewers. Any disagreements that arise between the reviewers during the study selection process or data extraction will be resolved through discussion, or with a third reviewer. Results will be presented in tabular or diagrammatic form, together with a narrative summary.

E-learning on antibiotic prescribing-the role of autonomous motivation in participation: a prospective cohort study

Objectives

E-learning is increasingly used in education on antimicrobial stewardship, but participation rates are often low. Insight into factors that affect participation is therefore needed. Autonomous motivation is associated with higher achievements in medical education and could also play a role in e-learning participation. We therefore aimed to investigate the role of residents’ autonomous motivation in their participation in e-learning on antibiotic prescribing.

Methods

We performed a multicentre cohort study in two academic and two teaching hospitals. Residents who filled out questionnaires on antibiotic knowledge, the perceived importance of antibiotics and motivation [Self-Regulation Questionnaire – Academic (SRQ-a)] received e-learning access. We used the SRQ-a to calculate relative autonomous motivation (RAM), an index that estimates the amount of autonomous motivation compared with the amount of controlled motivation. We then analysed associations between RAM and participation in e-learning with logistic regression.

Results

Eighty-six residents participated (74% female, mean age 30 years). Overall e-learning participation was 58% (n = 50). Participation was 41% in residents with negative RAM (i.e. more controlled motivation) and 62% in residents with positive RAM (i.e. more autonomous motivation). RAM was positively associated with participation, adjusted for residency in an academic hospital (adjusted OR 2.6, 95% CI 1.5–4.6).

Conclusions

Participation in non-obligatory e-learning on antibiotic prescribing is higher in residents with more autonomous motivation. Interventions to increase autonomous motivation could improve participation. Preceding e-learning on antibiotic prescribing with face-to-face education, to explain the importance of the subject, could enhance autonomous motivation and thus optimize e-learning efficiency.

Antibiotic stewardship based on education: minor impact on knowledge, perception and attitude

Purpose: The purpose of this study was to implement an education-based antibiotic stewardship programme at two regional hospitals in Denmark, and thereby reduce consumption of antibiotics in general and cephalosporins and fluoroquinolones in particular. We aimed to improve physicians' knowledge, prescribing practices and perceptions and attitudes towards antibiotics, and to achieve changes in behaviour. Methods: The antibiotic stewardship programme comprised education, guidelines, audits and feedback and ward rounds by a clinical microbiologist. The ward rounds were implemented only at one hospital. The effects of the programme were evaluated using a questionnaire, audits of prescriptions (initial choice of antibiotics, indication for antibiotic treatment, re-assessment of treatment) and data on antibiotic consumption. Results: The survey revealed an improvement in junior doctors' knowledge, perception and attitude and self-reported prescribing practice. In the audit results, a larger proportion of prescribed antibiotics was in accordance with guidelines, particularly when we evaluated re-assessment of antibiotic treatment at the hospital where ward rounds had been implemented. The increase was equivalent to risk ratio (RR) 1.13 (95% confidence interval (CI): 0.95-1.35) during the intervention and RR 1.22 (95% CI 1.01-1.48) post-intervention, compared to the pre-intervention period. Penicillins as well as total antibiotic consumption increased during the study period. Conclusion: An education-based antibiotic stewardship programme can change the attitude of junior doctors and improve prescribing practices. We observed an improvement in the re-assessments of the antibiotic treatments at the hospital where a clinical microbiologist was present at ward rounds, but our persuasive methods were insufficient to reduce antibiotic consumption.

Perceptions, attitudes, and practices of French junior physicians regarding antibiotic use and resistance

OBJECTIVES

To assess the perceptions, attitudes, and practices of French junior physicians regarding antibiotic use and resistance, and then to identify the characteristics of junior physicians associated with appropriate practices of antibiotic use.

METHOD

European junior physicians received an email invitation to complete a 49 item web questionnaire between September 2015 and January 2016. We present the French data. Multivariate regression models were used to identify the characteristics of junior physicians associated with appropriate prescription practices and with consideration of the antibiotic prescription consequences.

RESULTS

The questionnaire was completed by 641 junior physicians: family medicine (37%), other medical specialties (e.g., pediatrics, internal medicine, neurology: 45%), surgical specialties (11%), and anesthesiology-intensive care specialty (7%). Most respondents (93%) declared being aware of the risk of bacterial resistance and 41% acknowledged prescribing antibiotics more often than necessary. Two factors were independently associated with appropriate prescription practices: a high perceived level of education on antibiotic use (OR=1.51; 95% CI [1.01-2.30]) and a medical specialty (OR=1.69; 95% CI [1.16-2.46]). Factors independently associated with taking into account adverse events of antibiotics were a good perceived knowledge of antibiotics (OR=3.71; 95% CI [2.09-6.61]), and a high perceived education level on antibiotics (OR=1.70; 95% CI [1.11-2.58]).

CONCLUSION

Our data can help better define interventions targeting junior physicians in antibiotic stewardship programs.

Observational multi-centre, prospective study to characterize novel pathogen-and host-related factors in hospitalized patients with lower respiratory tract infections and/or sepsis - the "TAILORED-Treatment" study

Background

The emergence and spread of antibiotic resistant micro-organisms is a global concern, which is largely attributable to inaccurate prescribing of antibiotics to patients presenting with non-bacterial infections. The use of ‘omics’ technologies for discovery of novel infection related biomarkers combined with novel treatment algorithms offers possibilities for rapidly distinguishing between bacterial and viral infections. This distinction can be particularly important for patients suffering from lower respiratory tract infections (LRTI) and/or sepsis as they represent a significant burden to healthcare systems. Here we present the study details of the TAILORED-Treatment study, an observational, prospective, multi-centre study aiming to generate a multi-parametric model, combining host and pathogen data, for distinguishing between bacterial and viral aetiologies in children and adults with LRTI and/or sepsis.

Methods

A total number of 1200 paediatric and adult patients aged 1 month and older with LRTI and/or sepsis or a non-infectious disease are recruited from Emergency Departments and hospital wards of seven Dutch and Israeli medical centres. A panel of three experienced physicians adjudicate a reference standard diagnosis for all patients (i.e., bacterial or viral infection) using all available clinical and laboratory information, including a 28-day follow-up assessment. Nasal swabs and blood samples are collected for multi-omics investigations including host RNA and protein biomarkers, nasal microbiota profiling, host genomic profiling and bacterial proteomics. Simplified data is entered into a custom-built database in order to develop a multi-parametric model and diagnostic tools for differentiating between bacterial and viral infections. The predictions from the model will be compared with the consensus diagnosis in order to determine its accuracy.

Discussion

The TAILORED-Treatment study will provide new insights into the interplay between the host and micro-organisms. New host- or pathogen-related biomarkers will be used to generate a multi-parametric model for distinguishing between bacterial and viral infections. This model will be helpful to better guide antimicrobial therapy for patients with LRTI and sepsis. This study has the potential to improve patient care, reduce unnecessary antibiotic prescribing and will contribute positively to institutional, national and international healthcare economics.

Emergency surgeons' perceptions and attitudes towards antibiotic prescribing and resistance: a worldwide cross-sectional survey

BACKGROUND

Antibiotic resistance (AMR) is a growing public health problem worldwide, in part related to inadequate antibiotic use. A better knowledge of physicians' motivations, attitudes and practice about AMR and prescribing should enable the design and implementation of effective antibiotic stewardship programs (ASPs). The objective of the study was to assess attitudes and perceptions concerning AMR and use of antibiotics among surgeons who regularly perform emergency or trauma surgery.

METHODS

A cross-sectional web-based survey was conducted contacting 4904 individuals belonging to a mailing list provided by the World Society of Emergency Surgery. Participation was voluntary and anonymous. The survey was open for 5 weeks (from May 3, 2017, to June 6, 2017), within which two reminders were sent. The self-administered questionnaire was developed by a multidisciplinary team; reliability and validity were assessed.

RESULTS

The overall response rate was 12.5%. Almost all participants considered AMR an important worldwide problem, but 45.6% of them underrated the problem in their own hospitals. Surgeons provided with periodic reports on local AMR demonstrated a lower underrating in their hospital. Only 66.3% of the surgeons stated to receive periodic reports on local AMR data, and among them, 56.2% had consulted them to select an antibiotic in the previous month. Availability of systematic reports about AMR, availability of guidelines for therapy of infections, and advice from an infectious diseases specialist were considered very helpful measures to improve antibiotic prescribing by 68.0, 65.7, and 64.9%, respectively. Persuasive and restrictive ASPs were both considered helpful measures by 64.5%. Moreover, 86.3% considered locally developed guidelines more useful than national ones. Only 21.9% received formal training in antibiotic prescribing in the previous year; among them, 86.6% declared to be interested in receiving more training.

CONCLUSIONS

Availability of periodic reports on local AMR data was considered an important tool to guide surgeons in choosing the correct antibiotic and to increase awareness of the problem of AMR. Local guidelines for therapy of infections should be implemented in every emergency surgery setting, and developed by a multidisciplinary team directly involving surgeons, infectious diseases specialists, and microbiologists, and formally established in an ASP.

ESGAP inventory of target indicators assessing antibiotic prescriptions: a cross-sectional survey

Background

A variety of indicators is commonly used to monitor antibiotic prescriptions as part of national antimicrobial stewardship (AMS) programmes.

Objectives

To make an inventory of indicators that assess antibiotic prescriptions and are linked to specific targets and incentives, at a national level.

Methods

A cross-sectional survey (three-item questionnaire) was conducted in 2017 among all ESGAP (ESCMID Study Group for Antimicrobial stewardshiP) members, coming from 23 European countries and 16 non-European countries.

Results

Almost all (20/23, 87%) European countries belonging to the ESGAP network participated, as well as one non-European country. Computerized systems routinely linking antibiotic prescriptions to clinical diagnoses were reported for only two countries (Turkey and Croatia). Only 6/21 (29%) countries had national indicators with both clear targets and incentives (Bulgaria, Croatia, France, the Netherlands, Norway and Portugal). We identified a total of 21 different indicators used in these countries, 16 concerning inpatients (9 quality indicators and 7 quantity metrics) and 8 concerning outpatients (all quantity metrics); some indicators were used in both settings. Three types of incentives were used: financing mechanism, hospitals' accreditation and public reporting. Some respondents reported that such indicators with both clear targets and incentives were used at a regional level in their country (e.g. Andalusia in Spain and England in the UK).

Conclusions

National indicators, with clear targets and incentives, are not commonly used in Europe and we observed wide variations between countries regarding the selected indicators, the units of measure and the chosen targets.

Prevalence and predictors of spontaneous bacterial peritonitis due to ceftriaxone-resistant organisms at a large tertiary centre in the USA

OBJECTIVES

The epidemiology of spontaneous bacterial peritonitis (SBP) due to ceftriaxone-resistant organisms has not been well studied in the USA. The primary objective of this study was to assess the prevalence and predictors of ceftriaxone-resistant SBP at a large US tertiary-care centre.

METHODS

This 1:1:4 case-case-control study included 141 adults with liver cirrhosis admitted from November 2011 to March 2016. Case group 1 were patients with SBP with a ceftriaxone-resistant organism (n=21). Case group 2 were patients with SBP with a ceftriaxone-susceptible organism (n=26). The control group were patients without SBP (n=94). Multiple logistic regression analysis was used to identify predictors of ceftriaxone-resistant SBP.

RESULTS

Fifty isolates were identified from 47 patients with culture-positive SBP (case groups 1 and 2). Of these 50 isolates, 32 (64%) were Gram-negatives [mostly Enterobacteriaceae (91%)], 15 (30%) were Gram-positives and 3 (6%) were Candida spp. The prevalence of ceftriaxone resistance in patients with culture-positive SBP was 45% (21/47). The most common ceftriaxone-resistant organisms were ESBL-producing Enterobacteriaceae (45%). Independent predictors of ceftriaxone-resistant SBP included duration of β-lactam therapy in the past 90days (aOR=1.07, 95% CI 1.01-1.13) and recent invasive gastrointestinal procedure (aOR=12.47, 95% CI 2.74-56.67).

CONCLUSIONS

The prevalence of ceftriaxone-resistant SBP was significant at a US tertiary centre. Local epidemiological data and identification of risk factors associated with ceftriaxone-resistant SBP, e.g. increased usage of previous β-lactam therapy and invasive gastrointestinal procedure, may help clinicians identify patients requiring alternative empirical antibiotics.

A systematic review of clinical decision support systems for antimicrobial management: are we failing to investigate these interventions appropriately?

OBJECTIVES

Clinical decision support systems (CDSS) for antimicrobial management can support clinicians to optimize antimicrobial therapy. We reviewed all original literature (qualitative and quantitative) to understand the current scope of CDSS for antimicrobial management and analyse existing methods used to evaluate and report such systems.

METHOD

PRISMA guidelines were followed. Medline, EMBASE, HMIC Health and Management and Global Health databases were searched from 1 January 1980 to 31 October 2015. All primary research studies describing CDSS for antimicrobial management in adults in primary or secondary care were included. For qualitative studies, thematic synthesis was performed. Quality was assessed using Integrated quality Criteria for the Review Of Multiple Study designs (ICROMS) criteria. CDSS reporting was assessed against a reporting framework for behaviour change intervention implementation.

RESULTS

Fifty-eight original articles were included describing 38 independent CDSS. The majority of systems target antimicrobial prescribing (29/38;76%), are platforms integrated with electronic medical records (28/38;74%), and have a rules-based infrastructure providing decision support (29/38;76%). On evaluation against the intervention reporting framework, CDSS studies fail to report consideration of the non-expert, end-user workflow. They have narrow focus, such as antimicrobial selection, and use proxy outcome measures. Engagement with CDSS by clinicians was poor.

CONCLUSION

Greater consideration of the factors that drive non-expert decision making must be considered when designing CDSS interventions. Future work must aim to expand CDSS beyond simply selecting appropriate antimicrobials with clear and systematic reporting frameworks for CDSS interventions developed to address current gaps identified in the reporting of evidence.

Exploring the coverage of antimicrobial stewardship across UK clinical postgraduate training curricula

OBJECTIVES

Antimicrobial resistance (AMR) is a global political and patient safety issue. With ongoing strategic interventions to improve the shape of UK postgraduate clinical training, ensuring that all clinicians have appropriate knowledge and practical skills in the area of AMR is essential. To assess this, a cross-sectional analysis was undertaken of the coverage and quality of antimicrobial stewardship (AMS)/AMR within UK postgraduate clinical training curricula.

METHODS

UK clinical specialty training curricula were identified. Topics and individual learning points relating to AMS or AMR were extracted for each specialty. Learning points were quality assessed against the expected level of clinical competence. Inter-specialty analysis was performed.

RESULTS

Overall 37 specialties were assessed, equating to 2318 topics and 42 527 learning points. Of these, 8/2318 (0.3%) topics and 184/42 527 (0.4%) learning points were related to AMS/AMR. Infectious diseases represented all eight topics and 43/184 (23%) of the learning points. In contrast, primary care, which is responsible for the highest proportion of antimicrobial usage, had no topics and only 2/1368 (0.15%) of the AMS/AMR learning points. This paucity of representation was reflected across most of the remaining specialties. On quality assessment, the majority of learning points (111/184; 60%) required knowledge only, with no demonstration of behaviour in clinical practice required.

CONCLUSIONS

Coverage of AMS/AMR is poor across the majority of UK postgraduate clinical training curricula, with little depth of learning required. Given the threat of AMR, and evolving changes in clinical training pathways, we call for cross-specialty action to address this current lack of engagement.

Amoxicillin-clavulanic acid prescriptions at the Greater Paris University Hospitals (AP-HP)

OBJECTIVE

We aimed to document amoxicillin-clavulanic acid prescription to improve the proper use of antibiotics in hospital settings. We used three criteria: quality of medical charts, adequacy of indications, and adequacy of treatment duration.

METHOD

This study was designed as a one-day point prevalence survey carried out by antibiotic lead specialists.

RESULTS

We included 387 prescriptions from 32 hospitals. Immunodeficiency was recorded as a risk factor in 30% of patients. Computerized prescriptions were observed in 79% of cases. The indication was mentioned in 73% of cases and a 48/78-hour re-assessment of the antibiotic therapy was performed in 54% of cases. The antibiotic indication was primarily for pneumonia and was deemed appropriate in 75% of patients. Adult mean treatment duration was 11.1 days. Use of dual combination therapy and/or treatment duration exceeding two weeks accounted for the main reasons for an inappropriate use of antibiotics. Prescriptions recorded as having been made by senior physicians were of the shortest treatment duration (P=0.0163).

CONCLUSION

Medical charts should be better filled in. Reinforcing the role of senior physicians in supervising antibiotic prescriptions is likely to result in a better control of treatment duration and ultimately in a reduced antibiotic consumption. By reinforcing the collaboration between pharmacists and antibiotic lead specialists, the improvement of computerized prescriptions at hospital level should help better detect the "at risk" prescriptions, namely those exceeding seven days or those combining antibiotics.

Misuse of antibiotics reserved for hospital settings in outpatients: a prospective clinical audit in a university hospital in Southern France

Some antibiotics are reserved essentially for hospital settings owing to cost effectiveness and in order to fight the emerging antibiotic resistance crisis. In some cases, antibiotics reserved exclusively for use in hospitals may be prescribed in outpatients for serious infections or in the absence of a therapeutic alternative. A 30-day prospective audit of outpatient prescriptions of antibiotics reserved exclusively for use in hospitals was performed. The objective of this study was to evaluate the relevance of outpatient antibiotic prescriptions by measuring appropriateness according to guidelines. During the study period, 53 prescriptions were included, only 40% of which were appropriate. Among the 32 inappropriate prescriptions, 4 cases lacked microbial arguments, 1 case was not adequate for the infection type, 1 case involved an incorrect antibiotic dosage, 1 case involved an incorrect interval of dose administration, 3 cases had a therapeutic alternative and 22 cases were not recommended. Of the 53 prescriptions, 66% were started in hospital and 34% in outpatients. Only 25% of cases were prescribed with infectious diseases specialist (IDS) advice, 64% were based on microbiological documentation and 13% had a negative bacterial culture. Inappropriate prescriptions were usually observed in antibiotic lock therapy, skin infections, Clostridium difficile colitis, intra-abdominal infections and intravascular catheter-related infections. Outpatient prescriptions of antimicrobial drugs reserved exclusively for use in hospitals are frequently inappropriate. We recommend a real-time analysis algorithm with the involvement of an IDS for monitoring prescriptions to improve the quality of these prescriptions and possibly to prevent antibiotic resistance.

Intern doctors' views on the current and future antibiotic resistance situation of Chattagram Maa O Shishu Hospital Medical College, Bangladesh

BACKGROUND

Bacterial resistance due to antibiotic misuse is reported every day. Such threat calls for a consensus to develop new strategies to prevent the development of antibiotic resistance of bacteria. Medical doctors must play a pivotal role to control and prevent the misuse of antibiotics. There were complaints that prescribers are lacking behind in updates and advancement in the field. To address such knowledge gap, a study was conducted to know the views of interns on the current antibiotic resistance situation in a teaching hospital in Bangladesh.

METHODS

This study was a cross-sectional, randomized, and questionnaire-based survey. Interns of the medicine, gynecology, and surgery departments of Chattagram Maa O Shishu Hospital Medical College were the study population.

RESULTS

Out of 50 respondents, 98% would like more education on antibiotic selection. All respondents believed that prescribing inappropriate or unnecessary antibiotics was professionally unethical. Ninety percent of the participants were confident in making an accurate diagnosis of infection. Eighty-four percent of them were confident about dosage schedule. In all, 98% participants thought that antibiotic resistance is a national problem and 64% of the respondents thought that same problem also existed in their hospital. Study participants were of the view that 41%-60% of antibiotic usages are irrational in Bangladesh. Fifty-eight percent of the study population thought that antimicrobial resistance (AR) would be a greater problem in the future.

CONCLUSION

The interns believe that there is a knowledge gap on AR. More emphasis should be given to AR and its implications in the undergraduate curriculum. Latest national and international guidelines for antimicrobial therapy and resistance should be made available to the interns.

The association of patient complexities with antibiotic ordering

BACKGROUND

Antibiotic treatment decisions for medically complex patients are complicated, as the risk of undertreatment may be severe, whereas overtreatment may be associated with adverse effects and the emergence of antibiotic resistant pathogens.

OBJECTIVE

To determine the influence of patient complexities on providers' decisions to prescribe antibiotics in 3 common hospital-based clinical vignettes.

DESIGN

A physician survey.

SETTING

Three urban medical centers in Los Angeles County, California.

PARTICIPANTS

Hospital-based physicians.

MEASUREMENTS

Physicians were presented 3 clinical vignettes, with variations by patient age, comorbidity burden, functional status, and follow-up, and asked to choose the best antibiotic regimen. We described the association of additional patient complexity on the proportion of guideline-adherent antibiotic choices.

RESULTS

In the survey, 28% to 49% of physicians recommended antibiotics that were inconsistent with national guidelines. This percentage increased to 48% to 63% for medically complex patients, defined as those with either older age, high medical comorbidity burden, poor functional status, or limited follow-up after hospital discharge (P < 0.01).

CONCLUSIONS

In 3 vignettes depicting common clinical scenarios among hospitalized adults, inappropriate antibiotic use was prevalent and occurred more often for patients with medical complexities. Treatment guidelines should consider addressing medically complex patients in the context of infection management.

[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.

Rapid and fully automated bacterial pathogen detection on a centrifugal-microfluidic LabDisk using highly sensitive nested PCR with integrated sample preparation

Diagnosis of infectious diseases suffers from long turnaround times for gold standard culture-based identification of bacterial pathogens, therefore impeding timely specific antimicrobial treatment based on laboratory evidence. Rapid molecular diagnostics-based technologies enable detection of microorganisms within hours however cumbersome workflows and complex equipment still prevent their widespread use in the routine clinical microbiology setting. We developed a centrifugal-microfluidic "LabDisk" system for rapid and highly-sensitive pathogen detection on a point-of-care analyser. The unit-use LabDisk with pre-stored reagents features fully automated and integrated DNA extraction, consensus multiplex PCR pre-amplification and geometrically-multiplexed species-specific real-time PCR. Processing merely requires loading of the sample and DNA extraction reagents with minimal hands-on time of approximately 5 min. We demonstrate detection of as few as 3 colony-forming-units (cfu) of Staphylococcus warneri, 200 cfu of Streptococcus agalactiae, 5 cfu of Escherichia coli and 2 cfu of Haemophilus influenzae in a 200 μL serum sample. The turnaround time of the complete analysis from "sample-to-result" was 3 h and 45 min. The LabDisk consequently provides an easy-to-use molecular diagnostic platform for rapid and highly-sensitive detection of bacterial pathogens without requiring major hands-on time and complex laboratory instrumentation.

A national network of infectious diseases experts

OBJECTIVES

The aim of this study was to consider the implementation of a network of infectious diseases (ID) experts to optimize the antibiotic prescriptions of community and hospital practitioners.

METHODS

An observational prospective study was conducted among ID experts in the Pays-de-la-Loire Region to evaluate the number of calls and to determine the practitioner's reasons for soliciting ID expertise. For each phone consultation, four criteria were recorded during 5 days: origin of the call (internal/external), kind of question (diagnostic/therapeutic) time spent for the advice provided, type of advice.

RESULTS

A total of 386 phone consultations for 20 infectious disease specialists were recorded during the study period (5 days); 81% were internal to the hospital, 7.7% from another hospital, and 11.3% from private practice, 56.3% of the questions concerned a therapeutic strategy, 21% a diagnostic advice, and 22.6% concerned both diagnosis and therapy. Two third of the questions were answered within 10minutes. In 68.7% of cases, the ID specialist answered immediately, 19.8% of calls required following-up the patient, 6% led to refer the patient to an ID consultation, and 5.5% to hospitalization.

CONCLUSION

The survey results stress the important need for such ID expertise, both in hospitals and in ambulatory medicine. Collaboration of ID specialists in a regional network would allow an easy and permanent access to antibiotic therapy advice for prescribers. This network would improve the quality and safety of care.

[Rational antibiotic prescribing. Challenges and successes]

Rational and prudent antibiotic prescribing strategies are important both for the hospital sector as well as for ambulatory medicine. Prerequisites are the availability of antibiotic use and antibiotic resistance data and of infrastructure and trained personnel needed for implementing and evaluating antibiotic policies. Currently, these requirements are not being met sufficiently in Germany. A major challenge in this country is the lack of adequately trained and experienced personnel. On the other hand there are several projects and initiatives supported in part within the national antibiotic resistance control program which have produced some progress and success. One example is GERMAP, the national antibiotic use and resistance atlas covering both human medicine and the veterinary field. Other examples are the recently improved program for continuous hospital antibiotic use, surveillance and feedback and the Antibiotic Stewardship (ABS) training program with establishment of an ABS expert network. Future perspectives include programs for evaluation of practice guideline adherence and the development and evaluation of quality of care indicators. Intermediate and long-term investment is needed in specialty training and certification of a sufficient number of infectious disease physicians, medical microbiologists and infection control doctors/hospital epidemiologists and hospital pharmacists.

Strategies to minimize antibiotic resistance

Antibiotic resistance can be reduced by using antibiotics prudently based on guidelines of antimicrobial stewardship programs (ASPs) and various data such as pharmacokinetic (PK) and pharmacodynamic (PD) properties of antibiotics, diagnostic testing, antimicrobial susceptibility testing (AST), clinical response, and effects on the microbiota, as well as by new antibiotic developments. The controlled use of antibiotics in food animals is another cornerstone among efforts to reduce antibiotic resistance. All major resistance-control strategies recommend education for patients, children (e.g., through schools and day care), the public, and relevant healthcare professionals (e.g., primary-care physicians, pharmacists, and medical students) regarding unique features of bacterial infections and antibiotics, prudent antibiotic prescribing as a positive construct, and personal hygiene (e.g., handwashing). The problem of antibiotic resistance can be minimized only by concerted efforts of all members of society for ensuring the continued efficiency of antibiotics.

Knowledge, attitudes, and beliefs of French medical students about antibiotic prescribing and resistance

OBJECTIVES

We had for aim to learn about medical students' knowledge and perspectives on antibiotic prescribing and bacterial resistance.

METHODS

Penultimate and final year students at a French medical school were invited to participate in an anonymous online survey in summer 2012.

RESULTS

The response rate was 20% (60/297). Penultimate and final year students gave similar answers. Students felt more confident in diagnosing an infection, and less confident in choosing the correct dose and interval of antibiotic administration. Seventy-nine percent of students wanted more training on antibiotic treatments. Sixty-nine percent of students knew that antibiotic prescriptions were inappropriate or unnecessary in 21-60% of the cases, and 95% believed that these prescriptions were unethical. Only 27% knew that more than 80% of antibiotic prescriptions were made in community practice. Students believed that the most important causes of resistance were that too many prescriptions were made and broad-spectrum antibiotic use; 27% believed poor hand hygiene was "not at all important". Ninety-four percent believed resistance was a national problem, and 69% mentioned it as a problem in their hospital. Sixty-three percent thought that the antibiotics they would prescribe would contribute to resistance, and 96% thought resistance would be a greater problem in the future. Twenty-two percent knew MRSA bacteremia rates had decreased over the past decade in France.

CONCLUSIONS

Medical students are aware that antibiotic resistance is a current and growing problem. They would like more training on antibiotic selection.

Assisted knowledge discovery for the maintenance of clinical guidelines

Background

Improving antibiotic prescribing practices is an important public-health priority given the widespread antimicrobial resistance. Establishing clinical practice guidelines is crucial to this effort, but their development is a complex task and their quality is directly related to the methodology and source of knowledge used.

Objective

We present the design and the evaluation of a tool (KART) that aims to facilitate the creation and maintenance of clinical practice guidelines based on information retrieval techniques.

Methods

KART consists of three main modules 1) a literature-based medical knowledge extraction module, which is built upon a specialized question-answering engine; 2) a module to normalize clinical recommendations based on automatic text categorizers; and 3) a module to manage clinical knowledge, which formalizes and stores clinical recommendations for further use. The evaluation of the usability and utility of KART followed the methodology of the cognitive walkthrough.

Results

KART was designed and implemented as a standalone web application. The quantitative evaluation of the medical knowledge extraction module showed that 53% of the clinical recommendations generated by KART are consistent with existing clinical guidelines. The user-based evaluation confirmed this result by showing that KART was able to find a relevant antibiotic for half of the clinical scenarios tested. The automatic normalization of the recommendation produced mixed results among end-users.

Conclusions

We have developed an innovative approach for the process of clinical guidelines development and maintenance in a context where available knowledge is increasing at a rate that cannot be sustained by humans. In contrast to existing knowledge authoring tools, KART not only provides assistance to normalize, formalize and store clinical recommendations, but also aims to facilitate knowledge building.

How to educate prescribers in antimicrobial stewardship practices

Widespread antimicrobial use has compromised its value, leading to a crisis of antimicrobial resistance. A major cause of misuse is insufficient knowledge of prescribing of antimicrobials in many categories of professionals. An important principle of antimicrobial stewardship is avoiding selection pressure in the patient, both on pathogen and commensal by avoiding unnecessary use, choosing the least broad-spectrum antibiotic, adequate doses, a good timing and the shortest possible duration. Up to now, most educational efforts have been targeted at professionals (mostly medical doctors) after their training and at the adult public. In the past few years, progress has been made in educating children. It is now crucial that academia and ministries of Health and Education jointly focus on an adapted undergraduate medical/professional curriculum that teaches all necessary principles of microbiology, infectious diseases and clinical pharmacology, with emphasis on the principles of prudent prescribing.
