Master of Pharmacy students' knowledge and awareness of antibiotic use, resistance and stewardship

Development and validation of a psychometric scale for assessing pharmacy students' perceptions and attitudes toward antimicrobial resistance and antimicrobial stewardship in Indonesia: the PATARAS study

Appropriate perceptions and attitudes of pharmacists toward antimicrobial resistance (AMR) are essential. However, AMR attitudes and perceptions have not been assessed in Indonesia. This study aimed to develop and validate a questionnaire to evaluate pharmacy students' Perceptions and Attitudes toward Antibiotic Resistance and Antimicrobial Stewardship (PATARAS) and investigate the relationship between students' perceptions and attitudes toward antibiotic resistance and stewardship. Using purposive sampling, 500 undergraduate pharmacy students were included in the study. The 20-item PATARAS questionnaire with 5-point Likert scales was developed. The PATARAS includes perception (rational drug use (RDU) and antimicrobial stewardship (AMS)) and attitude (professional role (PRO) and inappropriate practice (IPP)) domains. The validity (convergent and discriminant) of the PATARAS was investigated using confirmatory factor analysis (CFA). The CFA model fit was assessed using various goodness-of-fit indices. Reliability was assessed using Cronbach's alpha (α) and McDonald's Omega (ω) values. The relationship between subdomains was evaluated using structural equation modeling (SEM). The PATARAS questionnaire achieved acceptable convergent and discriminant validity. The CFA model achieved a good fit. The reliability was good with α and ω values of 0.817 and 0.845, respectively. The SEM showed that RDU and AMS were positively correlated with PRO (β = 0.121 and 0.539, respectively, p < 0.05); RDU and IPP were also positively correlated (β = 0.313, p < 0.05), while AMS and IPP were negatively correlated (β = - 0.275, p < 0.05). The PATARAS is a valid and reliable instrument for assessing undergraduate pharmacy students' perceptions and attitudes toward AMR and AMS.

Healthcare Professionals' Knowledge and Attitudes Toward Antimicrobial Stewardship Programs in Aseer, Saudi Arabia: A Cross-Sectional Study

Background

Antimicrobial stewardship programs (ASPs) are initiatives designed to reduce the spread of antimicrobial resistance (AMR). ASPs enhance antimicrobial use, prevent errors, maintain guidelines, and monitor usage to reduce AMR.

Objective

This study aims to shed light on healthcare professionals' (HCPs) knowledge, experience, and attitudes regarding ASPs.

Methods

This quantitative cross-sectional study, approved by the Research Ethics Committee at King Khalid University (ECM#2022-2023) was conducted in the Aseer region, Saudi Arabia. A validated self-administered online survey was distributed through various social media channels using snowball sampling between September 2022 and June 2024. The data from the online survey was analyzed using IBM SPSS Statistics.

Results

The sample included 388 participants. Just over half (53.1%) were male, and the remainder (46.9%) were female. Although a slight majority (54.9%) reported familiarity with ASPs, a professional practice gap was found; only 143 (36.9%) of the participants had direct experience working with such programs, while 64.7% reported inadequate training opportunities as a barrier to effective ASP implementation followed by lack of resources, lack of internal policies and guidelines, time constraints and lack of manpower (54.1%, 52.1%, 48.2% and 45.9%, respectively). Despite the high level of awareness across both genders and all HCPs, only half of the participants correctly identified that cutting antibiotic costs is not the primary goal of ASPs. There were significant differences among participants' views toward repeated education and online resources (p = 0.042 and p = 0.024, respectively).

Conclusion

While HCPs have a good understanding of AMR, a professional practice gap was found. Thus, the study recommends offering ongoing education and training programs for HCPs. Addressing implementation obstacles, such as resource limitations and unclear guidelines, is also essential.

Insights Into Antimicrobial Resistance From Dental Students in the Asia-Pacific Region

BACKGROUND

Dentists, as prominent prescribers, are key stakeholders in addressing the antimicrobial resistance (AMR) crisis. Dental students' perceptions about the topic have been underexplored in the Asia-Pacific region, a key location for the development and spread of AMR. Thus, the aim of this study was to evaluate the awareness and confidence to prescribe antimicrobials amongst dental students studying in the region.

METHODS

Students from 15 dental schools in 4 countries were invited to participate in a cross-sectional online survey during 2022-2023. A previously validated and standardised 14-item instrument was utilised.

RESULTS

In all, 1413 responses were collected from Australia (n = 165), Sri Lanka (n = 112), Japan (n = 173), and Vietnam (n = 963). Of those, 201 were from final-year students (14.2%). On a scale from 1 to 10, awareness on AMR was placed at a mean (SEM) priority of 8.09 (0.05). With regards to target areas to address for mitigation of the AMR crisis, participants placed general public awareness at the top (mean [SEM] 8.53 [0.05]). Final-year students presented a mean (SEM) level of confidence to prescribe antibiotics of 6.01 (0.14) on a scale from 1 to 10, whilst 59.7% and 56.8% indicated feeling pressured to prescribe by patients or when lacking time, respectively. Final-year students participating in research activities assigned a higher priority to AMR compared to their peers not involved in research (mean [SEM] 8.6 [0.19] vs 7.81 [0.16]; P = .01).

CONCLUSIONS

This study highlights a need for increased awareness and confidence to prescribe amongst dental students in the Asia-Pacific region, an understudied population thus far. To mitigate this issue, the implementation (followed by assessment) of local educational and antibiotic stewardship initiatives is warranted.

Knowledge, Awareness, and Perceptions Towards Antibiotic Use, Resistance, and Antimicrobial Stewardship Among Final-Year Medical and Pharmacy Students in Saudi Arabia

Background/Objectives: Antibiotic resistance (ABR) is a global crisis leading to increased mortality and economic burden. Antimicrobial stewardship (AMS) promotes responsible antibiotic use and prescribing practices to combat ABR. This study assessed the knowledge, awareness, and perceptions of final-year medical and pharmacy students in Saudi Arabia regarding antibiotic use, ABR, and AMS. Methods: A national cross-sectional survey was conducted from January to April 2024 using a 49-item questionnaire. The survey assessed knowledge of antibiotic use, ABR, and AMS using predefined scoring, while perceptions were evaluated with a 5-point Likert scale. Data were analyzed using descriptive statistics and Chi-square tests to explore associations between independent variables and outcomes. A logistic regression analysis identified factors associated with good knowledge, and results were reported as adjusted odds ratios (aOR) with 95% confidence intervals (CI). Results: Among 197 participants from 26 Saudi universities, pharmacy students comprised 73.1% of the sample. Good knowledge was observed in 44.7% for antibiotic use, 47.7% for ABR, and 52.8% for AMS. However, 28.4% lacked awareness of AMS, and 5.6% were unaware of ABR. Pharmacy students demonstrated significantly higher knowledge and confidence in AMS and antibiotic handling compared to medical students (p < 0.001). Higher knowledge was also associated with the university's region and prior education on resistance or AMS during college. Conclusions: This study highlights significant gaps in knowledge and awareness of antibiotic use, ABR, and AMS among final-year medical and pharmacy students in Saudi Arabia. The findings emphasize the need for targeted educational strategies, standardized curricula, and enhanced AMS training to better prepare future healthcare professionals to combat ABR effectively.

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.

Implementation of the national antimicrobial stewardship competencies for UK undergraduate healthcare professional education within undergraduate pharmacy programmes: a survey of UK schools of pharmacy

BACKGROUND

Pharmacists play a key role in antimicrobial stewardship (AMS). Consensus-based national AMS competencies for undergraduate healthcare professionals in the UK reflect the increasing emphasis on competency-based healthcare professional education. However, the extent to which these are included within undergraduate pharmacy education programmes in the UK is unknown.

OBJECTIVES

To explore which of the AMS competencies are delivered, including when and at which level, within UK undergraduate MPharm programmes.

METHODS

A cross-sectional online questionnaire captured the level of study of the MPharm programme in which each competency was taught, the method of delivery and assessment of AMS education, and examples of student feedback.

RESULTS

Ten institutions completed the survey (33% response rate). No institution reported covering all 54 AMS competencies and 5 of these were taught at half or fewer of the institutions. Key gaps were identified around taking samples, communication, outpatient parenteral antimicrobial therapy and surgical prophylaxis. The minimum time dedicated to AMS teaching differed between institutions (range 9-119 h), teaching was generally through didactic methods, and assessment was generally through knowledge recall and objective structured clinical examinations. Feedback from students suggests they find AMS and antimicrobial resistance (AMR) to be complex yet important topics.

CONCLUSIONS

UK schools of pharmacy should utilize the competency framework to identify gaps in their AMS, AMR and infection teaching. To prepare newly qualified pharmacists to be effective at delivering AMS and prescribing antimicrobials, schools of pharmacy should utilize more simulated environments and clinical placements for education and assessment of AMS.

Perceptions, attitudes, and practices of a Belgian teaching hospital's physicians, pharmacists, and nurses regarding antibiotic use and resistance: survey towards targeted actions for Antimicrobial Stewardship

OBJECTIVES

This study aimed to identify barriers to the proper use of antibiotics by healthcare professionals and to help the hospital Antimicrobial Stewardship develop suitable actions for the staff.

METHODS

In a Belgian teaching hospital, a survey was conducted among physicians, pharmacists, and nurses involved in antibiotherapy. Questions from the 2019 European Center for Disease Prevention and Control (ECDC) survey were analyzed based on components of the COM-B model (capabilities, opportunities, and motivations). First, collected data were reviewed with the Ethnos software to analyze the different COM-B model components. For statistical analyses, responses were grouped into three clear-cut answers in a Fisher's exact test.

RESULTS

Overall, 400 staff members were included. We found that our professions, combined, have a good perception of antibiotic resistance (97.8%). For capabilities, however, only 77.2% state that they have sufficient knowledge, with 91.3%, 71.5%, and 63.0% for physicians, nurses, and pharmacists, respectively. For opportunities (access to resources, information, and training), it is observed that 72.2% report having easy access to the guidelines they need to manage infections. In comparison, for 64.2% of the respondents, this information changed their opinion on the useless or inappropriate prescription, administration, and delivery of antibiotics. For 55.0%, this information has enabled them to change their practices. Finally, for motivations, 92.8% of respondents state that they know about the link between their practices and the emergence and spread of antibiotic resistance. However, only 65.0% of participants say they have a role in managing antibiotic resistance. We found that 5 out of 8 questions are significantly dependent on the profession: 2 inquiries related to capability, 1 to opportunity, and 2 to motivation.

CONCLUSION

We found that responses to the ECDC questionnaire are related to the profession. While some topics are universal/cross-functional, others must be explicitly tailored to each professional category. Information is useless if not accessible. Communication and provision of documents are thus paramount.

Awareness regarding antimicrobial resistance and confidence to prescribe antibiotics in dentistry: a cross-continental student survey

BACKGROUND

The antimicrobial resistance (AMR) crisis is a major global threat and one of its biggest drivers is the overuse of antibiotics in humans. Dentists are responsible for 5-10% antibiotic prescriptions worldwide and recent data suggest that knowledge and prescribing practices need improvement.

METHODS

A cross-sectional web-survey was sent to dental students from six universities in Norway, Canada, and Brazil. Topics addressed covered awareness, confidence to prescribe antibiotics, and education needs. Data were presented descriptively and statistical testing was employed to compare group means when applicable.

RESULTS

In total, 562 responses were collected across the three countries with a response rate of 28.6%. 'Antibiotic resistance' was among the highest priorities (scale 1-10) with an average of 8.86 (SEM ± 0.05), together with 'Gender inequality' (8.68 ± 0.07) and 'Climate change' (8.68 ± 0.07). Only 28.8% thought that Dentistry was engaged in national/international campaigns promoting awareness on the topic and 8.9% stated to have heard about the 'One Health' concept. Final year dental students showed an average confidence to prescribe antibiotics of 7.59 (± 0.14). Most students demonstrated interest in receiving additional education on all topics listed, with the three most pressing being 'antibiotic prescription for treatment of infections' (82.9%), 'drug interactions' (80.9%), and 'spread of antibiotic resistance' (79.6%). A trend was observed between higher awareness regarding the topic and higher confidence to prescribe.

CONCLUSIONS

There is a need to revisit dental education on antibiotic resistance with a global perspective and to create more stewardship initiatives that promote awareness on the topic.

Knowledge, Attitude, and Behavior about Antimicrobial Use and Resistance among Medical, Nursing and Pharmacy Students in Jordan: A Cross Sectional Study

The present study aimed to survey medical, nursing and pharmacy students' knowledge, attitude and practice regarding antimicrobial use and resistance. Additionally, the study assessed the teaching and assessment activities received regarding antibiotic use. A cross sectional online survey was distributed to undergraduate students currently in clinical studies in their degree program. A total of 716 medicine, nursing and pharmacy undergraduate students were included. Respondents scored more than 76% on knowledge on effective use, unnecessary use and associated side effects of antibiotics, and 65.2% regarding knowledge on the spread of antibiotic resistance. Some participants (21.0%) agreed or strongly agreed that there has been good promotion of prudent antimicrobial use. Students were aware (13.1%), unaware (29.1%), or unsure (57.8%) that there is a national action plan relating to antimicrobial resistance. A total of 62.8% of the respondents strongly agreed or agreed that they have a key role in helping control antibiotic resistance. Participants reported that they require more information about resistance to antibiotics (53.9%), medical conditions for which antibiotics are used (51.7%) and how to use antibiotics (51.0%). Discussion of clinical cases and vignettes and small group teaching were reported as very useful or useful teaching strategies (79.9% and 74.2%, respectively). The findings from this study determined the current situation in relation to education on prudent antimicrobial use for undergraduates and highlighted areas for informing better curriculum design.

Antibiotic use: A cross-sectional survey assessing the knowledge, attitudes, and practices amongst students of Punjab, Pakistan

Objective: The aim of the study was to assess the knowledge, attitudes and practices of students regarding the use of antibiotics in Punjab, Pakistan. Participants: 525 medical and non-medical students from Punjab in Pakistan. Methods: The t-test and ANOVA were used to compare the average response of respondents. Chi-square test was used to measure the association of different elements. Results: The mean age was 20.78 ± 2.10%. About 14% of the students agreed about the appropriateness of antibiotics for viral infections, and 15% of students said they stopped taking the drugs when symptoms subsided. 65.7% of students took antibiotics only when prescribed by a doctor and 54% bought antibiotics without prescription. Statistically significant results were found among the students who had heard about the antibiotic resistance (p < 0.05). Conclusion: This study will help assess the adequacy of current educational campaigns, maximize rationalization of antibiotic use, and minimize gaps in knowledge and attitudes.

Pharmacists’ Knowledge, Attitudes, Behaviors and Information Sources on Antibiotic Use and Resistance in Jordan

Antimicrobial resistance (AMR) is a serious healthcare problem that affects public health globally. Appropriate understanding and knowledge of prudent antimicrobial use and resistance, along with providing evidence-based information sources, are needed for informed antibiotic prescribing practices. This study aimed to assess the knowledge, opportunity, motivation, behavior of pharmacists and their information sources regarding antibiotic use and resistance in Jordan. An online cross-sectional questionnaire was developed and administered to pharmacists during the period of July–September 2021. The survey is an adapted version of the validated European Centre for Disease Prevention and Control (ECDC) survey for antibiotic use and resistance. Pharmacists from all sectors (n = 384), of whom 276 (71.9%) were community pharmacists, completed an online questionnaire. While respondents scored highly (>87%) on knowledge on effective use, unnecessary use, and associated side effects of antibiotics, lower scores were recorded for knowledge on the spread of antibiotic resistance (52.9%). Pharmacists support easy access to guidelines on managing infections in 56% of cases, and easy access to materials advising prudent antibiotic use and resistance in 39.8% of cases. One-third of respondents (37.0%) reported no knowledge of any initiatives on antibiotic awareness and resistance. Pharmacists were aware (13.3%), unaware (36.2%), or unsure (50.5%) of the existence of a national antibiotic resistance action plan. Pharmacists indicated an interest in receiving more information on resistance to antibiotics (55.2%), medical conditions for which antibiotics are used (53.1%), how to use antibiotics (45.1%), prescribing of antibiotics (34.4%), and links between the health of humans, animals, and the environment (28.6%). Findings can inform antimicrobial stewardship with required interventions to improve antibiotic use.

A natural history museum visitor survey of perception, attitude and knowledge (PAK) of microbes and antibiotics

A kiosk-based survey at the American Museum of Natural History in New York City in 2016-2018 allowed us to assess public knowledge of antibiotics and public attitudes toward microbes in museum goers. Over 22,000 visitors from 172 countries and territories answered several carefully designed questions about microbes and antibiotics. These visitors also entered age, gender, and country demographic data that allowed for stratification along these demographic and geographic divisions. Because museum goers are likely to be better informed about these and other science-based topics, the results described here can set a potential upper bound for public knowledge on these topics. Surprisingly, the results of our analysis of museum goers' answers about microbes and antibiotics indicate a substantial lack of familiarity with both topics. For example, overall only about 50% of respondents can correctly identify penicillin as an antibiotic and less than 50% of museum visitors view microbes as beneficial. The results described here suggest that we are perhaps off target with our educational efforts in this area and that a major shift in approach toward more basic microbial topics is warranted in our educational efforts.

Knowledge, Attitudes, and Practices of Spanish Midwives and Midwifery Students toward Oral Healthcare during Pregnancy

Pregnancy can affect the mother's oral health, increasing their susceptibility to oral diseases that have been associated with harmful effects on the newborn. Despite the severity of oral diseases during pregnancy, the demand for dental care during the gestational period is low, which may improve with the participation of midwives in promoting oral health activities. The objectives of this study were: (i) to determine the knowledge, attitudes, and practices of Spanish midwives and midwifery students regarding oral health in pregnant women; and (ii) to identify the barriers faced by these healthcare professionals in addressing oral health promotion during pregnancy. An observational cross-sectional descriptive study was conducted. A total of 128 midwives and/or midwifery students ≥ 18 years old and of both sexes were invited to self-complete a questionnaire between January and April 2020. A total of 85 people participated in the study. Participants had a regular level of knowledge about oral health during pregnancy (overall knowledge score: 6.53), and although they were interested in activities that promote oral healthcare, their oral healthcare practices during pregnancy were limited. As midwives play an important role in promoting health, their training in oral healthcare could help to improve pregnant women's oral health.

Exploring the practice, confidence and educational needs of hospital pharmacists in reviewing antimicrobial prescribing: a cross-sectional, nationwide survey

BACKGROUND

Antimicrobial stewardship (AMS) programs are usually limited in resources and scope. Therefore, wider engagement of hospital pharmacists in reviewing antimicrobial orders is necessary to ensure appropriate prescribing. We assessed hospital pharmacists' self-reported practice and confidence in reviewing antimicrobial prescribing, and their knowledge in making AMS interventions.

METHODS

We conducted an Australia-wide, cross-sectional survey in October 2017. A link to the online survey was emailed to hospital pharmacists via the Society of Hospital Pharmacists of Australia. Factors associated with higher knowledge scores were explored using linear regression models.

RESULTS

There were 439 respondents, of whom 272 (61.7%) were from metropolitan public hospitals. Pharmacists were more likely to assess the appropriateness of intravenous, broad-spectrum or restricted antibiotics than narrow-spectrum, oral antibiotics within 24-72 h of prescription; p < 0.001. Fifty percent or fewer respondents were confident in identifying AMS interventions related to dose optimization based on infection-specific factors, bug-drug mismatch, and inappropriate lack of spectra of antimicrobial activity. The median knowledge score (correct answers to knowledge questions) was 6 out of 9 (interquartile range, 5-7); key gaps were noted in antimicrobials' anaerobic spectrum, beta-lactam allergy assessment and dosing in immunocompromised patients. Clinical practice in inpatient areas, registration for 3-5 years and receipt of recent AMS education were associated with higher knowledge scores. More interactive modes of education delivery were preferred over didactic modes; p ≤ 0.01.

CONCLUSION

Gaps in practice, confidence and knowledge among hospital pharmacists were identified that could inform the design of educational strategies to help improve antimicrobial prescribing in Australian hospitals.

Understanding of Pharmacy Students towards Antibiotic Use, Antibiotic Resistance and Antibiotic Stewardship Programs: A Cross-Sectional Study from Punjab, Pakistan

Antibiotic resistance (ABR) is a significant issue for public health globally. An adequate understanding of ABR and the approaches used to tackle ABR, including antibiotic stewardship programs, are vital. This study aimed to get an insight into antibiotic use, ABR, and antibiotic stewardship programs among pharmacy students of Punjab, Pakistan. This multicenter study was undertaken among final (fifth) year undergraduate pharmacy students of 7 universities of Punjab, Pakistan. A paper-based self-administered questionnaire comprising 48-items was utilized for data collection. Descriptive and inferential statistics were employed for data analysis. This study included a total of 296 respondents with a response rate of 85.8%. Most of the students had an average understanding of antibiotic use (59.8%), ABR (42.6%), ABR mechanisms (48.0%), and factors of ABR (51.7%). Only 21.6% of students have heard about antibiotic stewardship programs. More than half of the students believed that educating and training healthcare professionals (53.4%) and medical students (57.8%) about the prescribing and judicial usage of antibiotics could reduce the ABR burden. The awareness of most of the pharmacy students about certain aspects of antibiotic use, ABR, and stewardship programs was suboptimal.

Knowledge, Attitudes, and Intentions towards HIV Pre-Exposure Prophylaxis among Nursing Students in Spain

Human immunodeficiency virus (HIV) infection is one of the main causes of morbidity and mortality worldwide. Among the preventive approaches proposed to control this disease is pre-exposure prophylaxis (PrEP), whose effectiveness depends on the medication adherence. The aim of the present study was to determine the knowledge and attitudes about PrEP among a sample of Spanish nursing students as well as their intentions of receiving it in case it was indicated. An observational cross-sectional descriptive study was carried out. A total of 570 nursing students from the University of Santiago de Compostela (Spain), ≥18 years old and of both sexes were invited to self-complete a questionnaire between February and March 2020. A total of 352 students decided to participate in the study. Participants had low knowledge [overall knowledge score 1(0-2)] and a neutral attitude towards PrEP. The intention of receiving PrEP improved significantly after the completion of the questionnaire and the administration of information about PrEP (p = 0.039; before: 23.58% and after: 93.77%). Nursing staff play an important role in the prevention of sexually transmitted diseases, so their training in preventive strategies, such as PrEP, could help to reduce the incidence of new cases of HIV infection.

Representing antibiotic relationships using measurements of efficacy against clinical isolates

Introduction. Antimicrobial resistance (AMR) is a worrying and confusing problem for both patients and medical professionals. It is often difficult for non-specialists to understand how different antibiotics are related to one another. Here, I use experimental data from hundreds of thousands of clinical isolates to infer relationships between antibiotics and represent them with simple diagrams. Methods. The minimum inhibitory concentration (MIC) of a bacterial isolate for a given antibiotic is defined as the lowest concentration that prevents visible growth. Measuring MICs for multiple antibiotics using the same isolate implicitly records the relationships of the antibiotics for a given species. The basic principle is that antibiotics with similar mechanisms of action should give rise to similar mechanisms of resistance, so should have correlated MICs across large numbers of isolates. This information can then be used to calculate distances between antibiotics based on pairwise correlations of their rank-ordered MICs. I apply this approach to a large historical AMR surveillance dataset (the Pfizer ATLAS surveillance dataset, 2004-2017). Results. I demonstrate that clustering antibiotics in this way allows a simple visual comparison of how similar antibiotics are to each other based on their efficacy within a species. The resulting visualizations broadly recapitulate antibiotic classes. They also clearly show the dramatic effects of combining beta-lactam antibiotics with beta-lactamase inhibitors, as well as highlighting antibiotics which have unexpected correlations in MICs that are not predicted from their chemical similarities alone. Conclusion. Large AMR surveillance datasets can be used in a hypothesis-free manner to show relationships between antibiotics based on their real-world efficacy.

Knowledge and self-confidence of antibiotic resistance, appropriate antibiotic therapy, and antibiotic stewardship among pharmacy undergraduate students in three Asian countries

BACKGROUND AND PURPOSE

Training pharmacy students in infectious diseases (ID) is important to enable them to participate in antibiotic stewardship programs. This study evaluated knowledge and self-confidence regarding antibiotic resistance, appropriate antibiotic therapy, and antibiotic stewardship among final year pharmacy undergraduate students.

METHODS

A cross-sectional electronic survey was conducted at universities in Indonesia, Malaysia, and Pakistan. A 59-item survey was administered between October 2017 and December 2017.

FINDINGS

The survey was completed by 211 students (response rate 77.8%). The mean knowledge score for antibiotic resistance, appropriate antibiotic therapy, and antibiotic stewardship was 5.6 ± 1.5, 4.7 ± 1.8 (maximum scores 10.0) and 3.1 ± 1.4 (maximum score 5.0), respectively. Significant variations were noted among the schools. There was poor awareness about the consequences of antibiotic resistance and cases with no need for an antibiotic. The knowledge of antibiotic resistance was higher among male respondents (6.1 vs. 5.4) and those who had attended antibiotic resistance (5.7 vs. 5.2) and antibiotic therapy (5.8 vs. 4.9) courses (p < 0.05). Students with ID clerkship experience (5.2 vs. 4.5) had significantly higher score for appropriate antibiotic therapy.

CONCLUSIONS

Final year pharmacy undergraduate students in Indonesia, Malaysia, and Pakistan had moderate knowledge of antibiotic resistance and antibiotic stewardship. However, the knowledge of appropriate antibiotic therapy was poor.

Knowledge, Attitude and Practice of Community Pharmacists Regarding Antibiotic Use and Infectious Diseases: A Cross-Sectional Survey in Hungary (KAPPhA-HU)

One of the key drivers for the emergence and spread of antimicrobial resistance (AMR) is non-prudent antibiotic (AB) use, which results in selection pressure towards relevant bacteria. Community pharmacists have pivotal roles in facilitating the prudent use of ABs that have been demonstrated by several studies worldwide. The aim of our present study was to evaluate the knowledge, attitude and practice of community pharmacists related to AB use and infectious diseases in Hungary. A descriptive cross-sectional survey was performed among community pharmacists in Hungary with the use of an anonymous, structured and pilot-tested questionnaire. Data collection ran between January 2016 and January 2018; n = 339 community pharmacists nationwide were approached with our questionnaire, out of which 192 filled out our survey. Hungarian pharmacists have appropriate knowledge regarding ABs and antimicrobial therapy, and they realize the public health impact of the growing AMR. Twenty-five percent of participants admitted to giving out non-prescription ABs at least once in the last year. The age and presence of board-certified specializations were shown to be significant factors of self-perceived knowledge and professional attitudes. Educational strategies and interventions specifically aimed at focusing on identified shortcomings and changing certain attitudes could substantially improve AB dispensing and AB use, in addition to minimizing resistance.

Nursing Students' Knowledge and Awareness of Antibiotic Use, Resistance and Stewardship: A Descriptive Cross-Sectional Study

Antibiotic resistance is an emerging worldwide concern with serious repercussions in terms of morbi-mortality. Bearing in mind that the inadequate use of antibiotics, by healthcare staff as well as by the general population, is one of its main causes, a multidisciplinary approach is required to try to combat it. The aim of the present study was to determine nursing students’ knowledge and awareness of antibiotic use, resistance and stewardship. A cross-sectional design was used. A total of 578 nursing students from the University of Santiago de Compostela (Spain), ≥18 years old of both sexes were invited to complete the Spanish version of the questionnaire “Knowledge and awareness of the use, resistance and administration of antibiotics” between February and April 2019. Students had a low level of knowledge about antibiotics, 4.1 (CI95% = 3.4–4.8), especially in relation to antibiotic resistance. As the students were aware of this deficiency, the majority affirmed (>90%) that the current curriculum of nursing degree should have more training on antibiotics and infection control. Nursing staff play an important role in the rational use of antibiotics and as teachers of patients, so their training could be key in fighting antibiotic resistance.

Antimicrobial stewardship education in US colleges and schools of pharmacy

Background

Pharmacists are key members of antimicrobial stewardship (AS) teams. It is unknown if and how US colleges and schools of pharmacy incorporate AS into their Doctor of Pharmacy (PharmD) curricula.

Methods

This study was a cross-sectional, multicentre, electronic survey distributed to infectious diseases faculty or department chairs of 137 accredited and candidate-status PharmD programmes.

Results

One hundred and sixteen programmes participated, representing an 84.7% response rate. AS education was integrated into the required didactic, elective didactic and experiential education components of the curricula in 79 (68.1%), 43 (37.1%) and 97 (83.6%) PharmD programmes, respectively. The most common AS topics in required and elective didactic curricula were AS definitions, principles and purpose (98.7% and 86.0%) and the pharmacist's role in AS (93.7% and 83.7%). In the required and elective didactic curricula, lecture (93.7% and 86.0%) and case-based instruction (57.0% and 83.7%) were the most common instructional methods. For experiential education, the pharmacist's role in AS (96.9%), de-escalation of antimicrobials (96.9%) and antimicrobial dose optimization (95.9%) were the most common AS topics. PharmD programmes employing a faculty member who specializes in AS were more likely to offer AS experiential education than programmes without AS faculty (88.1% versus 71.9%, P = 0.049).

Conclusions

Integration of AS education in US PharmD curricula is variable and there are considerable differences in the AS activities and topics delivered. PharmD programmes should attempt to expose students to AS education to prepare future pharmacists for AS practice. Efforts should be made to incorporate interprofessional collaboration into AS education.

Representing antibiotic relationships using measurements of efficacy against clinical isolates

Introduction. Antimicrobial resistance (AMR) is a worrying and confusing problem for both patients and medical professionals. Current antimicrobial nomenclature makes it difficult to understand how different antibiotics are related to one another, and their empirical uses and efficacy. Here, I attempt to address this problem by using experimental data from hundreds of thousands of clinical isolates to infer relationships between antibiotics and represent them with simple diagrams. Methods. The minimum inhibitory concentration (MIC) of a bacterial isolate for a given antibiotic is defined as the lowest concentration that prevents visible growth. Measuring MICs for multiple antibiotics using the same isolate implicitly records the relationships of the antibiotics for a given species. The basic principle is that antibiotics with similar mechanisms of action should give rise to similar mechanisms of resistance, so should have correlated MICs across large numbers of isolates. This information can then be used to calculate distances between antibiotics based on pairwise correlations of their rank-ordered MICs. I apply this approach to a large historical AMR surveillance dataset (the Pfizer ATLAS surveillance dataset, 2004-2017). Results. I demonstrate that clustering antibiotics in this way allows a simple visual comparison of how similar antibiotics are to each other based on their efficacy within a species. The resulting visualizations broadly recapitulate antibiotic classes. They also clearly show the dramatic effects of combining beta-lactam antibiotics with beta-lactamase inhibitors, as well as highlighting antibiotics which have unexpected correlations in MICs that are not predicted from their chemical similarities alone. Conclusion. Large AMR surveillance datasets can be used in a hypothesis-free manner to show relationships between antibiotics based on their real-world efficacy. The resulting 'data-driven' diagrams could be used as simple visual aids to explain the complexity of antibiotic relationships and AMR.

Knowledge, beliefs and practices on antibiotic use and resistance among a group of trainee nurses in Sri Lanka

Objectives

Nurses are the main communication link for healthcare messages to hospitalized patients and also play a crucial role in preventing the emergence and spread antibiotic resistant bacteria through antibiotic stewardship and infection control programmes. This requires them to possess correct knowledge and attitudes towards antibiotic use and resistance. This study was carried out to identify the level of knowledge, attitude and practices on antibiotic use and antibiotic resistance among student nurses.

Results

A descriptive cross-sectional study was conducted using a pre-validated, self-administered questionnaire with closed and open ended questions, among 199 student nurses at a government nurses training school in Sri Lanka. Scores and proportions were analysed with non-parametric methods and thematic analysis was done for the qualitative data. The study cohort had a mean knowledge score of 71.9% (SD 14). However, close to 40% believed that taking antibiotics will help to prevent cold from worsening and make recovery faster. Infection control was identified as the main method that nurses can engage in preventing antibiotic resistance. While the knowledge among our study cohort appeared to be good, some misbeliefs were present. Our findings can be used in developing the nursing curricula on antibiotic use and resistance.

Representing antibiotic relationships using measurements of efficacy against clinical isolates

Introduction. Antimicrobial resistance (AMR) is a worrying and confusing problem for both patients and medical professionals. Current antimicrobial nomenclature makes it difficult to understand how different antibiotics are related to one another, and their empirical uses and efficacy. Here, I attempt to address this problem by using experimental data from hundreds of thousands of clinical isolates to infer relationships between antibiotics and represent them with simple diagrams. Methods. The minimum inhibitory concentration (MIC) of a bacterial isolate for a given antibiotic is defined as the lowest concentration that prevents visible growth. Measuring MICs for multiple antibiotics using the same isolate implicitly records the relationships of the antibiotics for a given species. The basic principle is that antibiotics with similar activities have similar mechanisms of action. Therefore, they should produce similar resistances, so should have correlated MICs. This information can then be used to calculate distances between antibiotics based on pairwise correlations of their rank-ordered MICs. I apply this approach to a large historical AMR surveillance dataset (the Pfizer ATLAS surveillance dataset, 2004-2017). Results. I demonstrate that clustering antibiotics in this way allows a simple visual comparison of how similar antibiotics are to each other based on their efficacy within a species. The resulting visualizations broadly recapitulate antibiotic classes. They also clearly show the dramatic effects of combination therapies, as well as highlighting antibiotics which have unexpected correlations in MICs that are not predicted from their chemical similarities alone (i.e. suggesting co-occurring resistance mechanisms). Conclusion. Large AMR surveillance datasets can be used in a hypothesis-free manner to show relationships between antibiotics based on their real-world efficacy. The resulting 'data-driven' diagrams could be used as simple visual aids to explain the complexity of antibiotic relationships and AMR.

All aboard!: Involvement of medical and pharmacy trainees in antimicrobial stewardship

Antimicrobial stewardship (AS) involves the appropriate selection of antimicrobials. Antimicrobial stewardship programs are mandated in hospitals and are expanding to involve outpatient arenas. Multiple articles have been published describing the need for AS education for medical and pharmacy students, beginning early in the students’ career to develop into competent AS practitioners. Additionally, publications have described the role and impact of medical and pharmacy trainees on AS programs. Here, we review the published evidence describing medical and pharmacy trainees’ involvement in AS and call for future research in this area.

Role of the Clinical Microbiology Laboratory in Antimicrobial Stewardship

For adequate antimicrobial stewardship, microbiology needs to move from the laboratory to become physically and verbally amenable to the caregivers of an institution. Herein, we describe the contributions of our microbiology department to the antimicrobial stewardship program of a large teaching hospital as 10 main points ranging from the selection of patients deemed likely to benefit from a fast track approach, to their clinical samples, or the rapid reporting of results via a microbiology hotline, to rapid searches for pathogens and susceptibility testing. These points should serve as guidelines for similar programs designed to decrease the unnecessary use of antimicrobials.
