Effectiveness of interventions involving pharmacists on antibiotic prescribing by general practitioners: a systematic review and meta-analysis

Effectiveness of pharmacist-led antimicrobial stewardship programs in perioperative settings: A systematic review and meta-analysis

OBJECTIVE

We sought to characterize and evaluate the effectiveness of pharmacist-led AMS interventions in improving antimicrobial use and subsequent surgical site infections (SSI) in perioperative settings.

METHODS

A systematic review and meta-analysis was conducted by searching PubMed, Embase and CINAHL. Two independent reviewers extracted the data using the Descriptive Elements of Pharmacist Intervention Characterization Tool and undertook quality assessment using the Crowe Critical Appraisal. A meta-analysis was conducted using a random-effect model.

RESULTS

Eleven studies were included in this review. Pharmacists were found to have various roles in AMS, including educational sessions, ward rounds, audits and feedback, and guidelines development. The discussion of interventions lacked details on the development. A meta-analysis revealed that pharmacist-led AMS programs in perioperative settings was associated with a significant improvement in antibiotic selection (OR 4.29; 95 % CI 2.52-7.30), administration time (OR 4.93; 95 % CI 2.05-11.84), duration (OR 5.27; 95 % CI 1.58-17.55), and SSI (OR 0.51; 95 % CI 0.34-0.77).

CONCLUSION

Pharmacist-led AMS programs were effective in improving antimicrobial prescribing while reducing SSI; however most studies were of moderate quality. Studies lacked the utilization of theory to develop interventions, therefore, it is not clear whether theory-derived interventions are more effective than those without a theoretical element. High-quality, multicomponent, theory-derived, interventional studies using appropriate methodology and standardized data collection, are needed.

The impact of a multi-faceted intervention on non-prescription dispensing of antibiotics by urban community pharmacies in Indonesia: a mixed methods evaluation

INTRODUCTION

Non-prescription antibiotic dispensing is prevalent among community pharmacies in several low- and middle-income countries. We evaluated the impact of a multi-faceted intervention to address this challenge in urban community pharmacies in Indonesia.

METHODS

A pre-post quasi-experimental study was carried out in Semarang city from January to August 2022 to evaluate a 7-month long intervention comprising: (1) online educational sessions for pharmacists; (2) awareness campaign targeting customers; (3) peer visits; and (4) pharmacy branding and pharmacist certification. All community pharmacies were invited to take part with consenting pharmacies assigned to the participating group and all remaining pharmacies to the non-participating group. The primary outcome (rate of non-prescription antibiotic dispensing) was measured by standardised patients displaying symptoms of upper respiratory tract infection, urinary tract infection (UTI) and seeking care for diarrhoea in a child. χ2 tests and multivariate random-effects logistic regression models were conducted. Thirty in-depth interviews were conducted with pharmacists, staff and owners as well as other relevant stakeholders to understand any persistent barriers to prescription-based dispensing of antibiotics.

FINDINGS

Eighty pharmacies participated in the study. Postintervention, non-prescription antibiotics were dispensed in 133/240 (55.4%) consultations in the participating group compared with 469/570 (82.3%) in the non-participating group (p value <0.001). The pre-post difference in the non-prescription antibiotic dispensing rate in the participating group was 20.9% (76.3%-55.4%) compared with 2.3% (84.6%-82.3%) in the non-participating group (p value <0.001).Non-prescription antibiotics were less likely to be dispensed in the participating group (OR=0.19 (95% CI 0.09 to 0.43)) and more likely to be dispensed for the UTI scenario (OR=3.29 (95% CI 1.56 to 6.94)). Barriers to prescription-based antibiotic dispensing included fear of losing customers, customer demand, and no supervising pharmacist present.

INTERPRETATION

Multifaceted interventions targeting community pharmacies can substantially reduce non-prescription antibiotic dispensing. Future studies to evaluate the implementation and sustainability of this intervention on a larger scale are needed.

Development of an innovative clinical pharmacy service in a urology surgical unit: a new initiative from Qatar

Purpose

To provide an insight into the role of a clinical pharmacy initiative in a surgical urology unit through evaluating the nature, significance, associated medications, and acceptance rate of pharmacist interventions.

Methods

A cross-sectional study was carried out at the Ambulatory Care Center (ACC), Doha, Qatar. Data related to clinical pharmacist interventions and associated rationale were classified according to the nature of the intervention using an adapted classification system. The assessment of the severity followed the National Patient Safety Agency (NPSA) Risk Matrix. Linear regression, Kruskal-Wallis, and post-hoc analyses were performed to determine the association between patient-related and medication-related characteristics on pharmacist interventions.

Results

A total of 3284 interventions (on 1486 patients) were analysed. Most patients (n = 1105; 74.4%) had 1-2 interventions. Age and gender showed a positive linear correlation with the number of interventions per patient (p < 0.01). Majority of interventions were related to pharmacological strategy (n = 1858; 56.6%) and quantity of drug (n = 821; 25%). Additional drug therapy (n = 748; 22.78%) was the most common subcategory followed by optimum dose/frequency (n = 691; 21.04%) and discontinuation of medications (n = 352, 10.72%). Anti-infectives were the most identified drug category (n = 798, 55.1%). Most interventions (59.4%) were of moderate significance; patients with moderate interventions were found to be older compared to patients with minor interventions (p = 0.032). Prescribers' acceptance rate was high (>90%), with a notable increase of 6.6% from 2021 to 2023.

Conclusion

This study showed that the clinical pharmacy service in the urology surgical field was a fruitful initiative. The clinical pharmacist's role has expanded to include not only therapeutic optimisation while ensuring medication safety across the continuum of perioperative care but also the identification and management of untreated health problems. The dynamic and complexity of the urology patient population challenge clinical pharmacists; however, the practice concepts remain the same as in any other clinical setting.

A comparison between antibiotic utilisation in public and private community healthcare in Malaysia

BACKGROUND

There are two parallel systems in Malaysian primary healthcare services: government funded public primary care and privately-owned practices. While there have been several studies evaluating antibiotic utilisation in Malaysian public healthcare, there is a lack of literature on the use of antibiotics in the private sector. There is a dire need to evaluate the more recent performance of public vs. private community healthcare in Malaysia. As such, this study aimed at measuring and comparing the utilisation of antibiotics in the public and private community healthcare sectors of Malaysia in 2018-2021.

METHODS

This study was a retrospective analysis of antibiotic utilisation in Malaysian primary care for the period of 1 January 2018 until 31 December 2021 using the nationwide pharmaceutical procurement and sales data from public and private health sectors. Rates of antibiotic utilisation were reported as Defined Daily Doses per 1000 inhabitants per day (DID) and stratified by antibiotic classes. The secondary analysis included proportions of AWaRe antibiotic category use for each sector and proportion of antibiotic utilisation for both sectors.

RESULTS

The overall national antibiotic utilisation for 2018 was 6.14 DID, increasing slightly to 6.56 DID in 2019, before decreasing to 4.54 DID in 2020 and 4.17 DID in 2021. Private primary care antibiotic utilisation was almost ten times higher than in public primary care in 2021. The public sector had fewer (four) antibiotic molecules constituting 90% of the total antibiotic utilisation as compared to the private sector (eight). Use of Access antibiotics in the public sector was consistently above 90%, while use of Access category antibiotics by the private sector ranged from 64.2 to 68.3%. Although use of Watch antibiotics in the private sector decreased over the years, the use of Reserve and 'Not Recommended' antibiotics increased slightly over the years.

CONCLUSION

Antibiotic consumption in the private community healthcare sector in Malaysia is much higher than in the public sector. These findings highlight the need for more rigorous interventions targeting both private prescribers and the public with improvement strategies focusing on reducing inappropriate and unnecessary prescribing.

Academic Detailing is a Preferred Knowledge Update Tool Among Norwegian Pharmacists to Improve Antibiotic Counseling: Results From a Quantitative Study Employing the Provider Satisfaction With Academic Detailing (PSAD) and the Detailer Assessment of Visit Effectiveness (DAVE) Tools

Excessive and incorrect use of antibiotics contributes to the rise of antimicrobial resistance (AMR). Given that pharmacists act as final checkpoint before antibiotics is handled over to patients, they play a crucial role in promoting proper antibiotic use and ensuring treatment adherence. However, there is often a gap between the patients' needs and perceptions, and what the pharmacists provide. Improving pharmacists' training is essential for enhancing patient-centered care. The aim of this research was to evaluate the suitability of academic detailing (AD) for improving Norwegian pharmacists' knowledge and practice on adherence promoting counseling of antibiotic patients. Key insights from prior qualitative research regarding community pharmacists' position in promoting optimized antibiotic use were incorporated in a tailored AD program. The AD's suitability was evaluated using the validated "Provider Satisfaction with Academic Detailing" (PSAD) and "Detailer Assessment of Visit Effectiveness" (DAVE) instruments. Additionally, participants preferred knowledge updates method were assessed. Eighty-one of 86 visits completed PSAD (94% response rate). Satisfaction summary score for PSAD was 40.03 (of maximum 45) and scale summary score for DAVE 12.45 (of maximum 15). One-sample t-test (P < .001) indicated preference for AD over other knowledge update methods. This study confirmed that AD is a successful knowledge updating tool for improving adherence promoting counseling among Norwegian pharmacists. Future research should align practice change intentions with actions post-AD and evaluate patient impact.

Positioning of community pharmacists in interactions with general practitioners and patients regarding prescribing and using antibiotics

Interprofessional collaboration between general practitioners (GPs) and community pharmacists (CPs) is important for ensuring antibiotics are used correctly and combating antibiotic resistance. The study's main objective was to investigate how CPs, GPs and patients, respectively, position CPs in their interactions with patients on antibiotic-related matters in Norwegian pharmacies. Seven focus-group interviews were performed. Data were analyzed using systematic text condensation. Positioning theory was used to identify positions assigned to CPs by themselves, by GPs and by patients. CPs position themselves as helpful, accessible drug specialists responsible for advising on antibiotic use, but also consider themselves dependent on GP-supplied information to do so. GPs position CPs as helpful, responsible businesspeople who, however, lack clinical experience and are overzealous gatekeepers. Patients position CPs as helpful people who supply information in "everyday language" and as the GP's extended arm. Patients utter they are best served when GPs and CPs collaborate. This discrepancy is a barrier to optimal service to patients in general, and to proper antibiotic use in particular.

[Audit of Antibiotic Dispensing in Community Pharmacy (Happy Patient Project)]

Background

Dispensing and prescribing antibiotics is inappropriate in many of the countries in the European Union, including Spain, and a threat to the population's health. To tackle the growth of antimicrobial resistance, the Happy Patient project was set up under the sponsorship of the European Commission.

Aim

O ascertain the characteristics of dispensing antibiotic therapy in Spanish community pharmacies.To compare the variability between different Spanish community pharmacies.

Methods

The Audit Project Odense® methodology was used to find out how antibiotics were dispensed in community pharmacies. Pharmacists taking part were asked to record for five consecutive days between the months of February and April 2022 the actions performed during the dispensing of oral antibiotics for human use and for the treatment of acute infections.

Results

A total population of 573 patients (59.9% female) of all age groups were interviewed. The patients were 83.6% aware of the purpose for which the antibiotic was prescribed and the most requested antibiotic was amoxicillin followed by amoxicillin with clavulanic acid.In 15% of dispensations, a triple safety check was completed: interactions, contraindications and allergies. The pharmacist rarely contacted the prescriber but when she did, the prescriber altered the prescription.In 62.3% of cases, information about the duration of treatment was provided and amoxicillin with and without clavulanic acid was the antibiotic dispensed for which most warnings about side effects were issued. In 24.6% of dispensations there was no advice given at all. In 81.7% the pharmacist agreed with the prescribed treatment.

Conclusions

This audit can be a starting point to improve clinical practice and reduce antibiotic resistance. It highlights the need for safety checks in regard to the use of antimicrobials and suggests verifying dispensing to correct errors that may jeopardize the safety and effectiveness of antimicrobial therapy.

Adherence and utilization of short-term antibiotics: Randomized controlled study

Enhancing adherence to medication has the potential to improve clinical outcomes and decrease healthcare cost. The role of clinical pharmacist-led education on adherence to short-term antibiotic has never been investigated in Jordan. This study aimed to evaluate the impact of an educational intervention on antibiotic short-term adherence and to assess the antibiotic utilization pattern. A prospective, single blinded, randomized controlled study was conducted in a tertiary referral hospital in Jordan. Adult patients diagnosed with acute infection and prescribed a short-term antibiotic course (< 30 day) were included in the study. Recruited patients were randomly allocated into control and intervention groups. Pharmaceutical education about the correct use of antibiotic/s was provided to the intervention group. The results showed that penicillins were the most prescribed antibiotics (38.7%) followed by fluoroquinolones (23.9%) and cephalosporines (20.9%). Patients in the intervention group were more likely to be adherent to the prescribed antibiotics compared to control group (OR = 1.445, 95CI% = 1.029-2.030, p = 0.033). Employed patients, less frequent administration of antibiotic, and searching information related to the prescribed antibiotics were factors associated with better adherence to short-term antibiotic (p<0.05). The most common reasons for non-adherence were feeling better and forgetfulness to take medication. These findings highlighted that pharmacist-led educational intervention significantly enhance adherence to prescribed short-term antibiotics which is a major drive to control antibiotic resistance. Initiatives should be adopted to include patient education as a regular element in the medication dispensing process. Clinical trial registration: The trial is registered at ClinicalTrials.gov (identifier: NCT05293977).

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.

The National Implementation of a Community Pharmacy Antimicrobial Stewardship Intervention (PAMSI) through the English Pharmacy Quality Scheme 2020 to 2022

Since 2020, England's Pharmacy Quality Scheme (PQS) has incentivised increased antimicrobial stewardship (AMS) activities in community pharmacy. In 2020/21, this included the requirement for staff to complete an AMS e-Learning module, pledge to be an Antibiotic Guardian and develop an AMS Action plan. To build and embed these initiatives, in 2021/22, the PQS required the use of the TARGET Antibiotic Checklist (an AMS tool for use when patients present with a prescription for antibiotics to support conducting and recording of a series of safety and appropriateness checks against each prescribed antibiotic). This paper describes the implementation of the national PQS criteria from 2020 to 2022, and details community pharmacies' AMS activities and barriers to implementation of the 2021/22 criteria. A total of 8374 community pharmacies submitted data collected using the TARGET Antibiotic Checklist for 213,105 prescriptions; 44% surpassed the required number for the PQS. Pharmacy teams reported checking the following: duration, dose, and appropriateness of antibiotics; patient allergies and medicine interactions (94-95%); antibiotic prescribing guideline adherence (89%); and the patient's previous use of antibiotics (81%). The prescriber was contacted for 1.3% of TARGET Antibiotic Checklists (2741), and the most common reasons for such contacts were related to dose, duration, and possible patient allergy. A total of 105 pharmacy staff responded to a follow-up questionnaire, which suggested that some AMS principles had been embedded into daily practice; however, the necessary time commitment was a barrier. The PQS was able to incentivise mass AMS activities at pace over consecutive years for England's community pharmacies simultaneously. Future research should monitor the continuation of activities and the wider impacts on primary care.

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.

Is Education Alone Enough to Sustain Improvements of Antimicrobial Stewardship in General Practice in Australia? Results of an Intervention Follow-Up Study

Sustained behaviour change and practice improvements for the optimal use of antimicrobials remains challenging in primary care. In 2018, a simple antimicrobial stewardship education programme involving guideline recommendations for common infections, antimicrobial audit reports, and local antibiograms resulted in significant improvements in guideline compliance and more appropriate antimicrobial prescribing by GPs. This observational follow-up study aims to examine the sustainability of the positive intervention effect after two years of implementation of the intervention. Practice-based data on all oral antimicrobial prescriptions issued by GPs were collected retrospectively to compare with intervention data and to measure the sustainability of the intervention effect. The data were analysed using a two-sample test of proportions. The primary outcomes included changes in the rate of prescription compliance with the Australian “Therapeutic Guidelines: Antibiotic” and the appropriateness of antimicrobial choice and duration of therapy. Overall, there was a significant decline in guideline compliance, from 58.5 to 36.5% (risk ratio (RR) (95% CI): 0.62 (0.52–0.74)), in the appropriateness of antimicrobial choice, from 92.8 to 72.8% (0.78 (0.73, 0.84)), and in the prescribed duration, from 87.7 to 53.3% (0.61 (0.54, 0.68)) in the intervention follow-up period. In respiratory infections and ear, nose, and throat infections, the rates of guideline compliance and appropriate choice and duration of antimicrobial prescription decreased significantly at p < 0.001. Appropriateness in the duration of antimicrobial therapy also significantly decreased for most antimicrobials. The evidence suggests that a simple and single-occasion antimicrobial stewardship education programme is probably not enough to sustain improvements in the optimal use of antimicrobials by GPs. Future research is needed to validate the results in multiple GP clinics and to examine the effect of sustained education programmes involving infection-specific and antimicrobial-targeted audits and feedback.

The role of the clinical pharmacist in antimicrobial stewardship in Asia: A review

Clinical pharmacist-driven antimicrobial stewardship programs (ASPs) have been successfully implemented. Although relevant guidance and several studies suggest that clinical pharmacists be integrated into the current ASP team model, barriers still exist in Asia, primarily due to lack of dedicated personnel and lack of career advancement. We review the effectiveness and the ideal role of clinical pharmacist among ASPs in Asia. Several studies conducted in Asia have shown the effectiveness of pharmacist-led ASP interventions in hospitals and other healthcare settings. However, opportunities to expand the role of clinical pharmacists in ASPs in Asia exist in the implementation of rapid diagnostic test and drug allergies.

Exploring Antimicrobial Stewardship Influential Interventions on Improving Antibiotic Utilization in Outpatient and Inpatient Settings: A Systematic Review and Meta-Analysis

Antimicrobial stewardship interventions are targeted efforts by healthcare organizations to optimize antimicrobial use in clinical practice. The study aimed to explore effective interventions in improving antimicrobial use in hospitals. Literature was systemically searched for interventional studies through PubMed, CINAHL, and Scopus databases that were published in the period between January 2010 to April 2022. A random-effects model was used to pool and evaluate data from eligible studies that reported antimicrobial stewardship (AMS) interventions in outpatient and inpatient settings. Pooled estimates presented as proportions and standardized mean differences. Forty-eight articles were included in this review: 32 in inpatient and 16 in outpatient settings. Seventeen interventions have been identified, and eight outcomes have been targeted. AMS interventions improved clinical, microbiological, and cost outcomes in most studies. When comparing non-intervention with intervention groups using meta-analysis, there was an insignificant reduction in length of stay (MD: -0.99; 95% CI: -2.38, 0.39) and a significant reduction in antibiotics' days of therapy (MD: -2.73; 95% CI: -3.92, -1.54). There were noticeable reductions in readmissions, mortality rates, and antibiotic prescriptions post antimicrobial stewardship multi-disciplinary team (AMS-MDT) interventions. Studies that involved a pharmacist as part of the AMS-MDT showed more significant improvement in measured outcomes than the studies that did not involve a pharmacist.

A Novel GPPAS Model: Guiding the Implementation of Antimicrobial Stewardship in Primary Care Utilising Collaboration between General Practitioners and Community Pharmacists

Interprofessional collaboration between general practitioners (GPs) and community pharmacists (CPs) is central to implement antimicrobial stewardship (AMS) programmes in primary care. This study aimed to design a GP/pharmacist antimicrobial stewardship (GPPAS) model for primary care in Australia. An exploratory study design was followed that included seven studies conducted from 2017 to 2021 for the development of the GPPAS model. We generated secondary and primary evidence through a systematic review, a scoping review, a rapid review, nationwide surveys of Australian GPs and CPs including qualitative components, and a pilot study of a GPPAS submodel. All study evidence was synthesised, reviewed, merged, and triangulated to design the prototype GPPAS model using a Systems Engineering Initiative for Patient Safety theoretical framework. The secondary evidence provided effective GPPAS interventions, and the primary evidence identified GP/CP interprofessional issues, challenges, and future needs for implementing GPPAS interventions. The framework of the GPPAS model informed five GPPAS implementation submodels to foster implementation of AMS education program, antimicrobial audits, diagnostic stewardship, delayed prescribing, and routine review of antimicrobial prescriptions, through improved GP-CP collaboration. The GPPAS model could be used globally as a guide for GPs and CPs to collaboratively optimise antimicrobial use in primary care. Implementation studies on the GPPAS model and submodels are required to integrate the GPPAS model into GP/pharmacist interprofessional care models in Australia for improving AMS in routine primary care.

Pharmacist beliefs about antimicrobial resistance and impacts on antibiotic supply: a multinational survey

Background

Pharmacists have important antimicrobial stewardship (AMS) roles yet limited literature exists on pharmacists' knowledge and beliefs about antimicrobial resistance (AMR) and antimicrobials and how these beliefs influence antimicrobial supply in different countries.

Methods

A cross-sectional survey was disseminated to pharmacists around the world via the Commonwealth Pharmacists' Association and related networks. Data were collected on demographics, antibiotic supply practices, and knowledge and beliefs about AMR.

Results

A total of 546 pharmacists responded from 59 countries, most commonly from Africa (41%) followed by Asia (26%) and Oceania (22%). Respondents supplied a mean of 46 ± 81 antibiotic prescriptions/week, 73%±35% of which were given in response to a prescription. Overall, 60.2% dispensed antibiotics at least once without a prescription. Respondents had good knowledge (mean 9.6 ± 1.3 (out of 12), and held positive beliefs about AMR [mean 3.9 ± 0.6 (out of 5)]. Knowledge about antibiotics and beliefs about AMR were positively correlated. The odds of supplying antibiotics without a prescription were 7.4 times higher among respondents from lower income countries [adjusted odds ratio (AOR) = 7.42, 95% CI 4.16-13.24]. Conversely, more positive AMR beliefs were associated with a lower odds of supplying antibiotics without a prescription (AOR = 0.91, 95% CI 0.86-0.95).

Conclusions

Most pharmacists had the good knowledge about antibiotics and positive beliefs about AMR. These beliefs were influenced by knowledge, work setting, and country income. A proportion of respondents provided antibiotics without a prescription; the likelihood of this occurring was higher in those who held more negative beliefs about AMR.

A qualitative approach to examining antimicrobial prescribing in the outpatient dental setting

OBJECTIVE

To understand barriers and facilitators to evidence-based prescribing of antibiotics in the outpatient dental setting.

DESIGN

Semistructured interviews.

SETTING

Outpatient dental setting.

PARTICIPANTS

Dentists from 40 Veterans' Health Administration (VA) facilities across the United States.

METHODS

Dentists were identified based on their prescribing patterns and were recruited to participate in a semistructured interview on perceptions toward prescribing. All interviews were recorded, transcribed, and double-coded for analysis, with high reliability between coders. We identified general trends using the theoretical domains framework and mapped overarching themes onto the behavior change wheel to identify prospective interventions that improve evidence-based prescribing.

RESULTS

In total, 90 dentists participated in our study. The following barriers and facilitators to evidence-based prescribing emerged as impacts on a dentist's decision making on prescribing an antibiotic: access to resources, social influence of peers and other care providers, clinical judgment, beliefs about consequences, local features of the clinic setting, and beliefs about capabilities.

CONCLUSIONS

Findings from this work reveal the need to increase awareness of up-to-date antibiotic prescribing behaviors in dentistry and may inform the best antimicrobial stewardship interventions to support dentists' ongoing professional development and improve evidence-based prescribing.

Contributions and challenges of community pharmacists during the COVID-19 pandemic: a qualitative study

Background

Healthcare services across the world have been deeply impacted by the COVID-19 pandemic. In primary care, community pharmacists have had an important role in the frontline healthcare response to the pandemic.

Objectives

This study aimed to explore the experiences, contributions and perceived challenges of community pharmacists regarding the provision of healthcare services during the COVID-19 pandemic.

Methods

Semi-structured qualitative interviews were conducted with community pharmacists in France. Participants were recruited through a professional organization of pharmacists combined with a snowballing technique. Interviews were transcribed and then analyzed using thematic analysis.

Results

A total of 16 community pharmacists participated in the interviews. Study participants described providing a range of novel services in response to the pandemic on top of continuing their usual services. All participants described providing preventative services to reduce and mitigate the spread of SARS-CoV-2, such as education on hygiene and social distancing, delivery of face masks and hand sanitizer and adjusting pharmacy premises. Most respondents also described being involved in SARS-CoV-2 detection through screening and performing antigen testing in pharmacies. Participants reported being actively involved in COVID-19 vaccination by educating the general public about vaccines, facilitating their distribution to general practitioners as well as administering vaccines. Over half the respondents described rapidly changing guidelines and service users’ anxiety as challenges to the provision of healthcare services during the pandemic.

Conclusions

This study suggests that community pharmacists have significantly contributed to the response to the COVID-19 pandemic by ensuring continuity of pharmaceutical services and providing novel screening, testing and vaccination services. Their roles and responsibilities during the COVID-19 health crisis indicate that they can play an important role in the management of emerging infectious diseases.

Effectiveness of preconception care interventions in primary care: a systematic review protocol

BACKGROUND

Pregnancy outcomes can be adversely affected by a range of modifiable risk factors, including alcohol consumption, smoking, obesity, drug use, and poor nutrition, during the preconception period. Preconception care (PCC) involves interventions that identify and seek to change behavioural, biomedical, and social risks present in reproductive-aged women and men. Primary care is well situated to offer PCC interventions but the effectiveness of these interventions is not clear.

AIM

To evaluate the effectiveness of primary care-based PCC delivered to reproductive-aged women and/or men to improve health knowledge, reduce preconception risk factors, and improve pregnancy outcomes.

DESIGN & SETTING

A systematic review of primary care-based PCC.

METHOD

Ovid MEDLINE, Cochrane Central Register of Controlled Trials, Embase, Web of Science, Scopus, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases will be searched for English language studies published between July 1999 and May 2021. For inclusion, the PCC intervention must be provided in a primary care setting and intervention recipients must be reproductive-aged women and/or men. All stages of screening and data extraction will involve a dual review. The Cochrane Risk of Bias 2 (RoB 2) for randomised controlled trials (RCTs) will be used to assess the methodological quality of studies. This protocol adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) reporting guidelines.

CONCLUSION

Findings will determine the effectiveness of primary care-based preconception interventions delivered to reproductive-aged women and men on improving health knowledge, reducing risk factors, and improving pregnancy outcomes. Findings will be published in a peer-reviewed journal.

General Practitioners', Pharmacists' and Parents' Views on Antibiotic Use and Resistance in Malta: An Exploratory Qualitative Study

BACKGROUND

Antibiotic resistance (ABR) remains a global health threat that requires urgent action. Antibiotic use is a key driver of ABR and is particularly problematic in the outpatient setting. General practitioners (GPs), the public, and pharmacists therefore play an important role in safeguarding antibiotics. In this study, we aimed to gain a better understanding of the antibiotic prescribing-use-dispensation dynamic in Malta from the perspective of GPs, pharmacists, and parents; Methods: we conducted 8 focus groups with 8 GPs, 24 pharmacists, and 18 parents between 2014 and 2016. Data were analysed using inductive and deductive content analysis; Results: Awareness on antibiotic overuse and ABR was generally high among interviewees although antibiotic use was thought to be improving. Despite this, some believed that antibiotic demand, non-compliance, and over-the-counter dispensing are still a problem. Nevertheless, interviewees believed that the public is more accepting of alternative strategies, such as delayed antibiotic prescription. Both GPs and pharmacists were enthusiastic about their roles as patient educators in raising knowledge and awareness in this context; Conclusions: While antibiotic use and misuse, and knowledge and awareness, were perceived to have improved in Malta, our study suggests that even though stakeholders indicated willingness to drive change, there is still much room for improvement.

Barriers and facilitators of implementing interventions to improve appropriate antibiotic use in low- and middle-income countries: a systematic review based on the Consolidated Framework for Implementation Research

Background

Behavior change interventions that aim to improve rational antibiotic use in prescribers and users have been widely conducted in both high- and LMICs. However, currently, no review has systematically examined challenges unique to LMICs and offered insights into the underlying contextual factors that influence these interventions. We adopted an implementation research perspective to systematically synthesize the implementation barriers and facilitators in LMICs.

Methods

We conducted literature searches in five electronic databases and identified studies that involved the implementation of behavior change interventions to improve appropriate antibiotic use in prescribers and users in LMICs and reported implementation barriers and facilitators. Behavior change interventions were defined using the behavior change wheel, and the coding and synthesis of barriers and facilitators were guided by the Consolidated Framework for Implementation Research (CFIR).

Results

We identified 52 eligible studies, with the majority targeting prescribers practicing at tertiary facilities (N=39, 75%). The most commonly reported factors influencing implementation were found in the inner setting domain of the CFIR framework, particularly related to constraints in resources and the infrastructure of the facilities where interventions were implemented. Barriers related to the external policy environment (e.g., lack of national initiatives and policies on antibiotic use), and individual characteristics of target populations (e.g., reluctance to change prescribing behaviors) were also common, as well as facilitators related to intervention characteristics (e.g., embedding interventions in routine practice) and process (e.g., stakeholder engagement). We also provided insights into the interrelationships between these factors and the underlying causes contributing to the implementation challenges in LMICs.

Conclusion

We presented a comprehensive overview of the barriers and facilitators of implementing behavior change interventions to promote rational antibiotic use in LMICs. Our findings suggest that facilitating the implementation of interventions to improve rational antibiotic use needs comprehensive efforts to address challenges at policy, organizational, and implementation levels. Specific strategies include (1) strengthening political commitment to prompt mobilization of domestic resources and formulation of a sustainable national strategy on AMR, (2) improving the infrastructure of health facilities that allow prescribers to make evidence-based clinical decisions, and (3) engaging local stakeholders to improve their buy-in and facilitate contextualizing interventions.

Impact of an infectious diseases pharmacist-led intervention on antimicrobial stewardship program guideline adherence at a Thai medical center

DISCLAIMER

In an effort to expedite the publication of articles related to the COVID-19 pandemic, AJHP is posting these manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time.

PURPOSE

To evaluate and compare antimicrobial stewardship program (ASP) guideline adherence (primary outcome) as well as length of stay, 30-day all-cause mortality, clinical cure, antimicrobial consumption, and incidence of multidrug-resistant (MDR) pathogens (secondary outcomes) between an infectious diseases (ID) pharmacist-led intervention group and a standard ASP group.

METHODS

A quasi-experimental study was performed at Thammasat University Hospital between August 2019 and April 2020. Data including baseline characteristics and primary and secondary outcomes were collected from the electronic medical record by the ID pharmacist.

RESULTS

The ASP guideline adherence in the ID pharmacist-led intervention group was significantly higher than in the standard ASP group (79% vs 56.6%; P < 0.001), especially with regard to appropriate indication (P < 0.001), dosage regimen (P = 0.005), and duration (P = 0.001). The acceptance rate of ID pharmacist recommendations was 81.8% (44/54). The most common key barriers to following recommendations were physician resistance (11/20; 55%) and high severity of disease in the patient (6/20; 30%). Compared to the standard ASP group, there was a trend toward clinical cure in the ID pharmacist-led intervention group (63.6% vs 56.1%; P = 0.127), while 30-day all-cause mortality (15.9% vs 1.5%; P = 0.344) and median length of stay (20 vs 18 days; P = 0.085) were similar in the 2 groups. Carbapenem (P = 0.042) and fosfomycin (P = 0.014) consumption declined in the ID pharmacist-led intervention group. A marginally significant decrease in the overall incidence of MDR pathogens was also observed in the ID pharmacist-led intervention group (coefficient, -5.93; P = 0.049).

CONCLUSION

Our study demonstrates that an ID pharmacist-led intervention can improve ASP guideline adherence and may reduce carbapenem consumption.

Clinical Decision Support Systems for Antibiotic Prescribing: An Inventory of Current French Language Tools

Clinical decision support systems (CDSSs) are increasingly being used by clinicians to support antibiotic decision making in infection management. However, coexisting CDSSs often target different types of physicians, infectious situations, and patient profiles. The objective of this study was to perform an up-to-date inventory of French language CDSSs currently used in community and hospital settings for antimicrobial prescribing and to describe their main characteristics. A literature search, a search among smartphone application stores, and an open discussion with antimicrobial stewardship (AMS) experts were conducted in order to identify available French language CDSSs. Any clinical decision support tool that provides a personalized recommendation based on a clinical situation and/or a patient was included. Eleven CDSSs were identified through the search strategy. Of the 11 CDSSs, only 2 had been the subject of published studies, while 9 CDSSs were identified through smartphone application stores and expert knowledge. The majority of CDSSs were available free of charge (n = 8/11, 73%). Most CDSSs were accessible via smartphone applications (n = 9/11, 82%) and online websites (n = 8/11, 73%). Recommendations for antibiotic prescribing in urinary tract infections, upper and lower respiratory tract infections, and digestive tract infections were provided by over 90% of the CDSSs. More than 90% of the CDSSs displayed recommendations for antibiotic selection, prioritization, dosage, duration, route of administration, and alternative antibiotics in case of allergy. Information about antibiotic side effects, prescription recommendations for specific patient profiles and adaptation to local epidemiology were often missing or incomplete. There is a significant but heterogeneous offer for antibiotic prescribing decision support in French language. Standardized evaluation of these systems is needed to assess their impact on antimicrobial prescribing and antimicrobial resistance.

A systematic literature review and meta-analysis of community pharmacist-led interventions to optimise the use of antibiotics

Aims

The aim of this systematic review is to assess the effects of community pharmacist‐led interventions to optimise the use of antibiotics and identify which interventions are most effective.

Methods

This review was conducted according to the PRISMA guidelines (PROSPERO: CRD42020188552). PubMed, EMBASE and the Cochrane Central Register of Controlled Trials were searched for (randomised) controlled trials. Included interventions were required to target antibiotic use, be set in the community pharmacy context, and be pharmacist‐led. Primary outcomes were quality of antibiotic supply and adverse effects while secondary outcomes included patient‐reported outcomes. Risk of bias was assessed using the ‘Cochrane suggested risk of bias criteria’ and narrative synthesis of primary outcomes conducted.

Results

Seventeen studies were included covering in total 3822 patients (mean age 45.6 years, 61.9% female). Most studies used educational interventions. Three studies reported on primary outcomes, 12 on secondary outcomes and two on both. Three studies reported improvements in quality of dispensing, interventions led to more intensive symptom assessment (up to 30% more advice given) and a reduction of over‐the‐counter supply up to 53%. Three studies led to higher consumer satisfaction, effects on adherence from nine studies were mixed (risk difference 0.04 [−0.02, 0.10]). All studies had unclear or high risks of bias across at least one domain, with large heterogeneity between studies.

Conclusions

Our review suggests some positive results from pharmacist‐led interventions, but the interventions do not seem sufficiently effective as currently implemented. This review should be interpreted as exploratory research, as more high‐quality research is needed.

A systems thinking approach for antimicrobial stewardship in primary care

INTRODUCTION

The establishment of antimicrobial stewardship (AMS) in primary care is central to substantially reduce the antimicrobial use and the associated risk of resistance. This perspective piece highlights the importance of systems thinking to set up and facilitate AMS programs in primary care.

AREAS COVERED

The challenges that primary care faces to incorporate AMS programmes is multifactorial: an implementation framework, relevant resources, team composition, and system structures remain under-researched, and these issues are often overlooked and/or neglected in most parts of the world. Progress in the field remains slow in developed countries but potentially limited in low- and middle-income countries.

EXPERT OPINION

The key AMS strategies to optimize antimicrobial use in primary care are increasingly known; however, health system components that impact effective implementation of AMS programs remain unclear. We highlight the importance of systems thinking to identify and understand the resource arrangements, system structures, dynamic system behaviors, and intra- and interprofessional connections to optimally design and implement AMS programs in primary care. An AMS systems thinking systemigram (i.e. a visual representation of overall architecture of a system) could be a useful tool to foster AMS implementation in primary care.

Antimicrobial stewardship in Australia: the role of qualitative research in programme development

Antimicrobial stewardship (AMS) in Australia is supported by a number of factors, including enabling national policies, sectoral clinical governance frameworks and surveillance programmes, clinician-led educational initiatives and health services research. A One Health research programme undertaken by the National Centre for Antimicrobial Stewardship (NCAS) in Australia has combined antimicrobial prescribing surveillance with qualitative research focused on developing antimicrobial use-related situational analyses and scoping AMS implementation options across healthcare settings, including metropolitan hospitals, regional and rural hospitals, aged care homes, general practice clinics and companion animal and agricultural veterinary practices. Qualitative research involving clinicians across these diverse settings in Australia has contributed to improved understanding of contextual factors that influence antimicrobial prescribing, and barriers and facilitators of AMS implementation. This body of research has been underpinned by a commitment to supplementing 'big data' on antimicrobial prescribing practices, where available, with knowledge of the sociocultural, technical, environmental and other factors that shape prescribing behaviours. NCAS provided a unique opportunity for exchange and cross-pollination across the human and animal health programme domains. It has facilitated synergistic approaches to AMS research and education, and implementation of resources and stewardship activities. The NCAS programme aimed to synergistically combine quantitative and qualitative approaches to AMS research. In this article, we describe the qualitative findings of the first 5 years.

Antimicrobial stewardship for surgical antibiotic prophylaxis and surgical site infections: a systematic review

Background Surgical site infections account for 14-17% of all healthcare-associated infections. Antimicrobial stewardship (AMS) are complementary strategies developed to optimize the use of antimicrobials. Aim to evaluate the effectiveness of AMS in promoting adherence to surgical antibiotic prophylaxis protocols in hospitalized patients, reducing surgical site infection rate and cost-benefit ratio. Method This systematic review of randomized clinical trials, non-randomized clinical trials and before and after studies was performed using Pubmed, Cochrane, Web of Science, Scopus, Embase, Google Scholar and ClinicalTrials.gov, in addition to reference lists of included studies. The risk of bias of studies was measured by the ROBINS-I checklist and the quality of the evidence synthesis by GRADE. Results Fourteen before and after design studies were included. In 85.7% of the studies, AMS was effective in increasing adherence to surgical antibiotic prophylaxis protocols and in 28.5%, there was reduction in surgical site infection rate. Three studies evaluated cost-benefit ratio and found a favorable impact. Eight (57%) studies were at risk of moderate bias and six had severe bias. The evaluation of the synthesis of evidence showed quality ranging from low to very low. Conclusion AMS, such as audit, feedback, education, implementation of a protocol, and a computer-assisted decision support methodology, appear to be effective in promoting adherence to surgical antibiotic prophylaxis protocols, reducing surgical site infection rate with a positive economic impact. However, more studies, particularly randomized clinical trials, are needed to improve the level of evidence of available information on AMS in order to favor decision-making.

Antimicrobial utilization and stewardship in patients with uncomplicated urinary tract infections managed by pharmacists in the community: A sub-study of the RxOUTMAP trial

BACKGROUND

Urinary tract infections (UTIs) often lead to suboptimal antibacterial use. Pharmacists are accessible primary care professionals who have an important role to play in antimicrobial stewardship. Our objective was to evaluate the appropriateness of pharmacists' antibacterial prescribing for patients with uncomplicated UTI.

METHODS

We conducted a prospective registry trial with 39 community pharmacies in New Brunswick, Canada. Adult patients were enrolled if they presented to the pharmacy with either symptoms of UTI with no current antibacterial treatment (pharmacist-initial arm) or an antibacterial prescription for UTI from a physician (physician-initial arm). Pharmacists assessed patients; patients with complicating factors or red flags for systemic illness or pyelonephritis were excluded. Pharmacists prescribed antibacterial therapy or modified antibacterial therapy, provided education only, or referred to a physician, as appropriate. Antibacterial therapy prescribed was compared between study arms.

RESULTS

Seven hundred fifty patients were enrolled (87% pharmacist-initial arm). The most commonly prescribed agents in the pharmacist-initial arm were nitrofurantoin (88.4%), sulfamethoxazole-trimethoprim (TMP-SMX) (7.8%), and fosfomycin (2.1%); in the physician-initial arm, nitrofurantoin (55.3%), TMP-SMX (25.5%), and fluoroquinolones (10.6%) were prescribed. Therapy was guideline concordant for 95.1% of patients in the pharmacist-initial arm and 35.1% of patients in the physician-initial arm (p < 0.001). For guideline-discordant therapy from physicians, pharmacists prescribed to optimize therapy for 45.9% of patients.

CONCLUSION

Treatment was highly guideline concordant when pharmacist initiated, with physicians prescribing longer treatment durations and more fluoroquinolones. This represents an important opportunity for antimicrobial stewardship interventions by pharmacists in the community.

Effectiveness of interventions aiming to reduce inappropriate drug prescribing: an overview of interventions

Objective

Inappropriate prescribing of drugs is associated with unnecessary harms for patients and healthcare costs. Interventions to reduce these prescriptions are widely studied, yet the effectiveness of different types of interventions remains unclear. Therefore, we provide an overview regarding the effectiveness of intervention types that aim to reduce inappropriate drug prescriptions, unrestricted by target drugs, population or setting.

Methods

For this overview, systematic reviews (SRs) were used as the source for original studies. EMBASE and MEDLINE were searched from inception to August 2018. All SRs aiming to evaluate the effectiveness of interventions to reduce inappropriate prescribing of drugs were eligible for inclusion. The SRs and their original studies were screened for eligibility. Interventions of the original studies were categorized by type of intervention. The percentage of interventions showing a significant reduction of inappropriate prescribing were reported per intervention category.

Key findings

Thirty-two SRs were included, which provided 319 unique interventions. Overall, 61.4% of these interventions showed a significant reduction in inappropriate prescribing of drugs. Strategies that were most frequently effective in reducing inappropriate prescribing were multifaceted interventions (73.2%), followed by interventions containing additional diagnostic tests (antibiotics) (70.4%), computer interventions (69.2%), audit and feedback (66.7%), patient-mediated interventions (62.5%) and multidisciplinary (team) approach (57.1%). The least frequently effective intervention was an education for healthcare professionals (50.0%).

Conclusion

The majority of the interventions were effective in reducing inappropriate prescribing of drugs. Multifaceted interventions most frequently showed a significant reduction of inappropriate prescribing. Education for healthcare professionals is the most frequently included intervention in this overview, yet this category is least frequently effective.

White Paper: Bridging the gap between surveillance data and antimicrobial stewardship in the outpatient sector-practical guidance from the JPIAMR ARCH and COMBACTE-MAGNET EPI-Net networks

Background

The outpatient setting is a key scenario for the implementation of antimicrobial stewardship (AMS) activities, considering that overconsumption of antibiotics occurs mainly outside hospitals. This publication is the result of a joint initiative by the JPIAMR ARCH and COMBACTE-MAGNET EPI-Net networks, which is aimed at formulating a set of target actions for linking surveillance data with AMS activities in the outpatient setting.

Methods

A scoping review of the literature was carried out in three research areas: AMS leadership and accountability; antimicrobial usage and AMS; antimicrobial resistance and AMS. Consensus on the actions was reached through a RAND-modified Delphi process involving over 40 experts in infectious diseases, clinical microbiology, AMS, veterinary medicine or public health, from 18 low-, middle- and high-income countries.

Results

Evidence was retrieved from 38 documents, and an initial 25 target actions were proposed, differentiating between essential or desirable targets according to clinical relevance, feasibility and applicability to settings and resources. In the first consultation round, preliminary agreement was reached for all targets. Further to a second review, 6 statements were re-considered and 3 were deleted, leading to a final list of 22 target actions in the form of a practical checklist.

Conclusions

This White Paper is a pragmatic and flexible tool to guide the development of calibrated surveillance-based AMS interventions specific to the outpatient setting, which is characterized by substantial inter- and intra-country variability in the organization of healthcare structures, maintaining a global perspective and taking into account the feasibility of the target actions in low-resource settings.

Pharmacist-led education-based antimicrobial stewardship interventions and their effect on antimicrobial use in hospital inpatients: a systematic review and narrative synthesis

BACKGROUND

Antimicrobial stewardship (AMS) programmes optimize antimicrobial use and address antimicrobial resistance. Pharmacists are often key agents of these programmes. The effectiveness of hospital-based AMS interventions when they are led by pharmacists, however, has not previously been reported.

AIM

To evaluate the effectiveness of pharmacist-led AMS interventions in improving antimicrobial use for hospital inpatients.

METHODS

Standard systematic review methods were used. The search strategies and databases used in a previous Cochrane review were applied. Studies that reported pharmacist-led AMS interventions were included. Narrative synthesis was used to report the findings. PRISMA guidelines were followed.

FINDINGS

From 6971 records retrieved and screened, 52 full-text articles were included. Most studies were undertaken in teaching hospitals (N = 45) and many were conducted in North America (N = 27). Most interventions targeted junior or ward physicians and lasted between one and six months. All studies evaluated educational interventions often in combination with other interventions and reported improvements 'in compliance with target AMS practice'. Greater compliance was achieved with multiple interventions. Pharmacist-led interventions reduced the duration of antimicrobial therapy without increasing mortality. No consistency of evidence was achieved in relation to interventions and reduced duration of hospital stay, nor infections due to antimicrobial resistance or occurrence of Clostridium difficile.

CONCLUSION

This is the first systematic review to evaluate the effectiveness of pharmacist-led AMS interventions in hospital inpatients. Education-based interventions were effective in increasing guideline compliance and reducing duration of antimicrobial therapy. Future hospital-based AMS programmes should consider the involvement of pharmacists to deliver and promote AMS interventions and programmes.

Clinical impact of accepting or rejecting a recommendation from a clinical decision support system-assisted antibiotic stewardship program

BACKGROUND

Outcomes associated with physician responses to recommendations from an antimicrobial stewardship program (ASP) at an individual patient level have not yet been assessed. We aimed to compare clinical characteristics and mortality risk among patients for whom recommendations from an ASP were accepted or refused.

METHODS

A prospective cohort study was performed with hospitalized adults who received intravenous or oral antimicrobials at a 677-bed academic centre in Canada in 2014-2017. We included patients with an alert produced by a clinical decision support system (CDSS) for whom a recommendation was made by the pharmacist to the attending physician. The outcome was 90-day in-hospital all-cause mortality.

RESULTS

We identified 3,197 recommendations throughout the study period, of which 2,885 (90.2%) were accepted. The median length of antimicrobial treatment was significantly shorter when a recommendation was accepted (0.26 versus 1.78 d; p < 0.001). Refusal of a recommendation was not associated with mortality (odds ratio 1.32; 95% confidence interval, 0.93 to 1.89; p = 0.12). The independent risk factors associated with in-hospital mortality were age, Charlson Comorbidity Index score, admission to a critical care unit, duration between admission and recommendation, and issuance of a recommendation on a carbapenem.

CONCLUSIONS

The duration of antimicrobial treatment was significantly shorter when a recommendation originating from a CDSS-assisted ASP program was accepted. Future prospective studies including potential residual confounding variables, such as the source of infection or physiological derangement, might help in understanding whether CDSS-assisted ASP will have a direct impact on patient mortality.

Clinical impact of pharmacist-led antibiotic stewardship programs in outpatient settings in the United States: A scoping review

Disclaimer

In an effort to expedite the publication of articles related to the COVID-19 pandemic, AJHP is posting these manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time.

Purpose

To provide an overview of the impact of pharmacist interventions on antibiotic prescribing and the resultant clinical outcomes in an outpatient antibiotic stewardship program (ASP) in the United States.

Methods

Reports on studies of pharmacist-led ASP interventions implemented in US outpatient settings published from January 2000 to November 2020 and indexed in PubMed or Google Scholar were included. Additionally, studies documented at the ClinicalTrials.gov website were evaluated. Study selection was based on predetermined inclusion criteria; only randomized controlled trials, observational studies, nonrandomized controlled trials, and case-control studies conducted in outpatient settings in the United States were included. The primary outcome was the observed differences in antibiotic prescribing or clinical benefits between pharmacist-led ASP interventions and usual care.

Results

Of the 196 studies retrieved for full-text review, a cumulative total of 15 studies were included for final evaluation. Upon analysis, we observed that there was no consistent methodology in the implementation of ASPs and, in most cases, the outcome of interest varied. Nonetheless, there was a trend toward improvement in antibiotic prescribing with pharmacist interventions in ASPs compared with that under usual care (P < 0.05). However, the results of these studies are not easily generalizable.

Conclusion

Our findings suggest a need for a consistent approach for the practical application of outpatient pharmacist-led ASPs. Managed care organizations could play a significant role in ensuring the successful implementation of pharmacist-led ASPs in outpatient settings.

Community pharmacist prescribing of antimicrobials: A systematic review from an antimicrobial stewardship perspective

Background:

Pharmacist prescribing authority is expanding, while antimicrobial resistance is an increasing global concern. We sought to synthesize the evidence for antimicrobial prescribing by community pharmacists to identify opportunities to advance antimicrobial stewardship in this setting.

Methods:

We conducted a systematic review to characterize the existing literature on community pharmacist prescribing of systemic antimicrobials. We searched MEDLINE, EMBASE and International Pharmaceutical Abstracts for English-language articles published between 1999 and June 20, 2019, as well as hand-searched reference lists of included articles and incorporated expert suggestions.

Results:

Of 3793 articles identified, 14 met inclusion criteria. Pharmacists are most often prescribing for uncomplicated urinary tract infection (UTI), acute pharyngitis and cold sores using independent and supplementary prescribing models. This was associated with high rates of clinical improvement (4 studies), low rates of retreatment and adverse effects (3 studies) and decreased health care utilization (7 studies). Patients were highly satisfied (8 studies) and accessed care sooner or more easily (7 studies). Seven studies incorporated antimicrobial stewardship into study design, and there was overlap between study outcomes and those relevant to outpatient antimicrobial stewardship. Pharmacist intervention reduced unnecessary prescribing for acute pharyngitis (2 studies) and increased the appropriateness of prescribing for UTI (3 studies).

Conclusion:

There is growing evidence to support the role of community pharmacists in antimicrobial prescribing. Future research should explore additional opportunities for pharmacist antimicrobial prescribing and ways to further integrate advanced antimicrobial stewardship strategies in the community setting.

Development of an antimicrobial stewardship implementation model involving collaboration between general practitioners and pharmacists: GPPAS study in Australian primary care

Background:

Rising antimicrobial resistance (AMR) in primary care is a growing concern and a threat to community health. The rise of AMR can be slowed down if general practitioners (GPs) and community pharmacists (CPs) could work as a team to implement antimicrobial stewardship (AMS) programs for optimal use of antimicrobial(s). However, the evidence supporting a GP pharmacist collaborative AMS implementation model (GPPAS) in primary care remains limited.

Aim:

With an aim to design a GPPAS model in Australia, this paper outlines how this model will be developed.

Methods:

This exploratory study undertakes a systematic review, a scoping review, nationwide surveys, and qualitative interviews to design the model. Medical Research Council (MRC) framework and Normalization Process Theory are utilized as guides. Reviews will identify the list of effective GPPAS interventions. Two AMS surveys and paired interviews of GPs and CPs across Australia will explore their convergent and divergent views about the GPPAS interventions, attitudes towards collaboration in AMS and the perceived challenges of implementing GPPAS interventions. Systems Engineering Initiative for Patient Safety (SEIPS 2.0) model and factor analyses will guide the structure of GPPAS model through identifying the determinants of GPPAS uptake. The implementable GPPAS strategies will be selected based on empirical feasibility assessment by AMS stakeholders using the APEASE (Affordability, Practicability, Effectiveness and cost-effectiveness, Acceptability, Side-effects and safety, Equity) criteria.

Discussion:

The GPPAS model might have potential implications to inform how to better involve GPs and CPs in AMS, and, to improve collaborative services to optimize antimicrobial use and reduce AMR in primary care.

Divergent and Convergent Attitudes and Views of General Practitioners and Community Pharmacists to Collaboratively Implement Antimicrobial Stewardship Programs in Australia: A Nationwide Study

Setting up an interprofessional team for antimicrobial stewardship (AMS) to improve the quality and safety of antimicrobial use in primary care is essential but challenging. This study aimed to investigate the convergent and divergent attitudes and views of general practitioners (GPs) and community pharmacists (CPs) about AMS implementation and their perceived challenges of collaboration to design a GP–pharmacist collaborative AMS (GPPAS) model. Nationwide surveys of GPs and CPs across Australia were conducted January-October 2019. Chi square statistics and a theoretical framework were used for comparative analyses of quantitative and qualitative data, respectively. In total, 999 participants responded to the surveys with 15.4% (n = 386) response rates for GPs and 30.7% (n = 613) for CPs. GPs and CPs were aware about AMS however their interprofessional perceptions varied to the benefits of AMS programs. CPs indicated that they would need AMS training; significantly higher than GPs (GP vs. CP; 46.4% vs. 76.5%; p < 0.0001). GPs’ use of the Therapeutic Guideline Antibiotic was much higher than CPs (83.2% vs. 45.5%; p < 0.0001). No interprofessional difference was found in the very-limited use of patient information leaflets (p < 0.1162) and point-of-care tests (p < 0.7848). While CPs were more willing (p < 0.0001) to collaborate with GPs, both groups were convergent in views that policies that support GP–CP collaboration are needed to implement GPPAS strategies. GP–pharmacist collaborative group meetings (54.9% vs. 82.5%) and antimicrobial audit (46.1% vs. 86.5%) models were inter-professionally supported to optimise antimicrobial therapy, but an attitudinal divergence was significant (p < 0.001). The challenges towards GP–CP collaboration in AMS were identified by both at personal, logistical and organisational environment level. There are opportunities for GP–CP collaboration to improve AMS in Australian primary care. However, strengthening GP–pharmacy collaborative system structure and practice agreements is a priority to improve interprofessional trust, competencies, and communications for AMS and to establish a GPPAS model in future.

Feasibility and Validity of a Framework for Antimicrobial Stewardship in General Practice: Key Stakeholder Interviews

There is little guidance about developing systems for antimicrobial stewardship (AMS) for general practice. A literature review identified six key components: governance, monitoring of antibiotic prescribing and resistance with feedback to prescribers, consultation support, education of the public and general practitioners, pharmacist and nurse involvement, and research, which were incorporated into a potential framework for the general practice context. Objectives: to determine the feasibility and validity of the proposed AMS framework. A secondary objective was to identify likely bodies responsible for implementation in Australia. We undertook interviews with 12 key stakeholders from government, research, and professional groups. Data were analysed with a thematic approach. The framework was considered valid and feasible. No clear organisation was identified to lead AMS implementation in general practice. The current volume-based antibiotic prescription monitoring system was considered insufficient. AMS education for the public, further development of GP education, and improved consultation support were strongly recommended. The role of community-based pharmacists and nurses is largely unexplored, but their involvement was recommended. A clear leader to drive AMS in general practice is essential for an action framework to gain traction. Monitoring and feedback of antibiotic prescribing require urgent development to include monitoring of prescribing appropriateness and patient outcomes.

Management of non-urgent paediatric emergency department attendances by GPs: a retrospective observational study

Background

Non-urgent emergency department (ED) attendances are common among children. Primary care management may not only be more clinically appropriate, but may also improve patient experience and be more cost-effective.

Aim

To determine the impact on admissions, waiting times, antibiotic prescribing, and treatment costs of integrating a GP into a paediatric ED.

Design and setting

Retrospective cohort study explored non-urgent ED presentations in a paediatric ED in north-west England.

Method

From 1 October 2015 to 30 September 2017, a GP was situated in the ED from 2.00 pm until 10.00 pm, 7 days a week. All children triaged as ‘green’ using the Manchester Triage System (non-urgent) were considered to be ‘GP appropriate’. In cases of GP non-availability, children considered non-urgent were managed by ED staff. Clinical and operational outcomes, as well as the healthcare costs of children managed by GPs and ED staff across the same timeframe over a 2-year period were compared.

Results

Of 115 000 children attending the ED over the study period, a complete set of data were available for 13 099 categorised as ‘GP appropriate’; of these, 8404 (64.2%) were managed by GPs and 4695 (35.8%) by ED staff. Median duration of ED stay was 39 min (interquartile range [IQR] 16–108 min) in the GP group and 165 min (IQR 104–222 min) in the ED group (P<0.001). Children in the GP group were less likely to be admitted as inpatients (odds ratio [OR] 0.16; 95% confidence interval [CI] = 0.13 to 0.20) and less likely to wait >4 hours before being admitted or discharged (OR 0.11; 95% CI = 0.08 to 0.13), but were more likely to receive antibiotics (OR 1.42; 95% CI = 1.27 to 1.58). Treatment costs were 18.4% lower in the group managed by the GP (P<0.0001).

Conclusion

Given the rising demand for children’s emergency services, GP in ED care models may improve the management of non-urgent ED presentations. However, further research that incorporates causative study designs is required.

Recommendations for Improving Antimicrobial Stewardship in Long-Term Care Settings Through Collaboration

Antimicrobial stewardship is a collaborative venture and antimicrobial stewardship in long-term care (LTC) settings is no exception. There are many barriers to implementing effective antimicrobial stewardship programs in LTC settings, including constrained financial resources, limited access to physicians and pharmacists with antimicrobial stewardship training, minimal on-site infectious syndrome diagnostics and laboratory expertise, and high rates of staff turnover. This article suggests that collaboration at the level of health care facilities and systems, with public health departments, with laboratory partners, and among personnel, including nursing staff, prescribers, and pharmacists, can lead to effective antimicrobial stewardship programs in LTC settings.

Antimicrobial stewardship by Australian community pharmacists: Uptake, collaboration, challenges, and needs

OBJECTIVE

To assess community pharmacists' (CPs') awareness and uptake of evidence-based antimicrobial stewardship (AMS) strategies, attitudes toward collaboration with general practitioners (GPs), and needs to improve AMS practices.

METHODS

A nationwide survey of randomly sampled community pharmacies across Australia was conducted in April-October 2019.

RESULTS

The response rate of CPs was 30.7% (613 of 2000) and 592 participating CPs (96.5%) described the key barriers to and facilitators of improving AMS. CPs (447 of 613, 72.9%) were familiar with AMS but felt that they would require training (468 of 612, 76.5%) and access to AMS practice guidelines (566 of 605, 93.6%). Respondents perceived that AMS programs could reduce the inappropriate use of antimicrobials (409 of 612, 66.8%) and the costs of treating infection (508 of 612, 83.0%). CPs often counseled patients (591 of 609, 97.0%) and reviewed drug interactions or allergies (569 of 607, 93.8%) before dispensing antimicrobials. Respondents less often used the national Therapeutic Guidelines: Antibiotic (274 of 602, 45.5%) or assessed guideline-compliance of prescribed antimicrobials (231 of 609, 37.9%). CPs were less likely to communicate with GPs (254 of 609, 41.8%) when an antimicrobial prescription was believed to be suboptimal and perceived that GPs are not receptive to their intervention regarding the antimicrobial choice (500 of 606, 82.6%) and dosage (416 of 606, 68.6%). Point-of-care tests (114 of 596, 19.1%) and patient information leaflets (149 of 608, 24.5%) were used uncommonly. Most respondents supported policies that could foster GP-pharmacist collaboration (560 of 606, 92.4%), limit accessibility of selected antimicrobials (420 of 604, 74.4%), and reduce repeat-dispensing of antimicrobial prescriptions (448 of 604, 74.2%). CPs faced interpersonal, interactional, structural, and resource-level barriers to collaborate with GPs for practicing AMS.

CONCLUSIONS

CPs are aware of the importance of sensible use of antimicrobials but have had limited training and resources to conduct AMS activities. Improving GPs' receptiveness and system structures for increased GP-CP collaboration seem to be a priority to accelerate CP-led AMS implementation. Further study is required to understand the views of stakeholders about the feasibility of implementing evidence-based GP-CP collaborative AMS approaches.

Measuring Antibiotic Stewardship Programmes and Initiatives: An Umbrella Review in Primary Care Medicine and a Systematic Review of Dentistry

Antibiotic stewardship aims to tackle the global problem of drug-resistant infections by promoting the responsible use of antibiotics. Most antibiotics are prescribed in primary care and widespread overprescribing has been reported, including 80% in dentistry. This review aimed to identify outcomes measured in studies evaluating antibiotic stewardship across primary healthcare. An umbrella review was undertaken across medicine and a systematic review in dentistry. Systematic searches of Ovid Medline, Ovid Embase and Web of Science were undertaken. Two authors independently selected and quality assessed the included studies (using Critical Appraisal Skills Programme for the umbrella review and Quality Assessment Tool for Studies with Diverse Designs for the systematic review). Metrics used to evaluate antibiotic stewardship programmes and interventions were extracted and categorized. Comparisons between medical and dental settings were made. Searches identified 2355 medical and 2704 dental studies. After screening and quality assessment, ten and five studies, respectively, were included. Three outcomes were identified across both medical and dental studies: All focused on antibiotic usage. Four more outcomes were found only in medical studies: these measured patient outcomes, such as adverse effects. To evaluate antibiotic stewardship programmes and interventions across primary healthcare settings, measures of antibiotic use and patient outcomes are recommended.

Feasibility Study of the World Health Organization Health Care Facility-Based Antimicrobial Stewardship Toolkit for Low- and Middle-Income Countries

Antimicrobial stewardship (AMS) has emerged as a systematic approach to optimize antimicrobial use and reduce antimicrobial resistance. To support the implementation of AMS programs, the World Health Organization developed a draft toolkit for health care facility AMS programs in low- and middle-income countries. A feasibility study was conducted in Bhutan, the Federated States of Micronesia, Malawi, and Nepal to obtain local input on toolkit content and implementation of AMS programs. This descriptive qualitative study included semi-structured interviews with national- and facility-level stakeholders. Respondents identified AMS as a priority and perceived the draft toolkit as a much-needed document to further AMS program implementation. Facilitators for implementing AMS included strong national and facility leadership and clinical staff engagement. Barriers included lack of human and financial resources, inadequate regulations for prescription antibiotic sales, and insufficient AMS training. Action items for AMS implementation included improved laboratory surveillance, establishment of a stepwise approach for implementation, and mechanisms for reporting and feedback. Recommendations to improve the AMS toolkit's content included additional guidance on defining the responsibilities of the committees and how to prioritize AMS programming based on local context. The AMS toolkit was perceived to be an important asset as countries and health care facilities move forward to implement AMS programs.

Impact of Pharmacist Intervention in Response to Automated Molecular Diagnostic Tests of Blood Culture Results

BACKGROUND

Rapid molecular diagnostic tests can aid in deescalating antimicrobial therapy prior to final culture and susceptibility reports.

OBJECTIVE

The purpose of this study was to determine whether a new workflow that incorporated pharmacist review of these results reduced time to change in antimicrobial therapy.

METHODS

This retrospective study analyzed pre- and post-implementation of pharmacist review of positive blood cultures analyzed by rapid diagnostics with clinical recommendations paged to providers. Patients 18 years of age or older initiated on empiric antibiotics were included. The primary outcome was the time to change to targeted antimicrobials. Other outcomes evaluated were rates of Clostridioides difficile (C difficile) infection, inpatient mortality, and intensive care unit and hospital lengths of stay.

RESULTS

A total of 199 patients were included, with 98 and 101 patients in the pre- and post-implementation groups, respectively. The median time to change to targeted antimicrobials was significantly reduced with pharmacist intervention from 18.35 to 8.43 hours (P = 0.042). The groups had similar rates of C difficile infection (1% vs 0%, P = 0.492) and mortality (7.1% vs 5%, P = 0.564). The post-group also had significant reductions in antibiotic days of therapy (10.5 vs 9 days, P = 0.014) and intensive care unit length of stay (3.04 vs 1.44 days, P = 0.046). Median hospital length of stay was similar between the pre- and post-groups (8.5 vs 8 days, P = 0.106), respectively.

CONCLUSION

Incorporating pharmacist review of rapid molecular results of blood cultures decreased time to change to targeted antimicrobials and reduced inpatient antibiotic days of therapy.

Establishing a pharmacist-prescriber partnership in publicly funded primary healthcare clinics to optimise antibiotic prescribing in the Western Cape: An exploratory study

Background

Promoting evidence-based antibiotic prescribing through successful antimicrobial stewardship (AMS) programmes is critical to preserving the effectiveness of antibiotics for common infections in primary care. This requires a coordinated multidisciplinary effort. Such pharmacist–prescriber partnerships have been effective in high-income countries (HICs). Yet, evidence generated in such countries is not always applicable because of different social determinants of health.

Methods

A multidisciplinary workshop was conducted with pharmacists and clinicians (doctors, nurses) on community-based antibiotic stewardship, the purpose of which was to explore how and where such partnerships might work in publicly funded primary care clinics in the greater Cape Metro region.

Results

Participants perceived that promoting effective AMS was a priority for South African primary healthcare. However, it was clear that there are many hurdles to overcome working in settings that are relatively resource-poor. Prescribing guidelines needed to be harmonised. Participants felt that staff training on the principles of AMS should be mandatory. Research was urgently needed to better understand their community’s understanding of antibiotic use and AMS, and to champion outreach projects in the community.

Conclusion

Important stakeholder perspectives in the community were highlighted to promote a multidisciplinary approach to AMS initiatives in primary care. These will need to be addressed to optimise antibiotic prescribing in the community.

A Nationwide Survey of Australian General Practitioners on Antimicrobial Stewardship: Awareness, Uptake, Collaboration with Pharmacists and Improvement Strategies

Implementing antimicrobial stewardship (AMS) programs is central to optimise antimicrobial use in primary care. This study aims to assess general practitioners’ (GPs’) awareness of AMS, uptake of AMS strategies, attitudes towards GP–pharmacist collaboration in AMS and future AMS improvement strategies. A paper-based survey of nationally representative GPs across Australia was conducted in 2019. Of 386 respondent GPs, 68.9% were familiar with AMS. Respondents most frequently used the Therapeutic Guidelines (TG) (83.2%, 321/385) and delayed antimicrobial prescribing (72.2%, 278/385) strategies, whereas few utilised point-of-care tests (18.4%, 71/382), patient information leaflets (20.2%, 78/384), peer prescribing reports (15.5%, 60/384) and audit and feedback (9.8%, 38/384). GPs were receptive to pharmacists’ recommendations on the choice (50.5%, 192/381) and dose (63%, 241/382) of antimicrobials, and more than 60% (235/381) supported a policy fostering increased GP–pharmacist collaboration. Most GPs agreed to have AMS training (72%, 278/386), integration of electronic TG (eTG) with prescribing software (88.3%, 341/386) and policies limiting the prescribing of selected antimicrobials (74.4%, 287/386) in the future. Conclusively, GPs are aware of the importance of judicious antimicrobial prescribing but inadequately uptake evidence-based AMS strategies. The majority of GPs support GP–pharmacist collaborative AMS approaches to optimise antimicrobial use. Developing a feasible GP–pharmacist collaborative AMS implementation model and facilitating stewardship resources and training could foster AMS activities in primary care.

Antimicrobial stewardship in the outpatient setting: A review and proposed framework

Antimicrobial misuse is still a significant problem, and most inappropriate use occurs in the outpatient setting. In this article, we provide a review of available literature on outpatient antimicrobial stewardship in primary care settings, and we propose a novel implementation framework.

Knowledge, Perceptions and Practices of Community Pharmacists Towards Antimicrobial Stewardship: A Systematic Scoping Review

The scope of antimicrobial stewardship (AMS) surveys on community pharmacists (CPs) is uncertain. This study examines the breadth and quality of AMS survey tools measuring the stewardship knowledge, perceptions and practices (KPP) of CPs and analyse survey outcomes. Following PRISMA-ScR checklist and Arksey and O’Malley’s methodological framework seven medical databases were searched. Two reviewers independently screened the literatures, assessed quality of surveys and KPP outcomes were analysed and described. Ten surveys were identified that assessed CPs’ AMS perceptions (n = 7) and practices (n = 8) but none that assessed AMS knowledge. Three survey tools had been formally validated. Most CPs perceived that AMS improved patient care (median 86.0%, IQR, 83.3–93.5%, n = 6), and reduced inappropriate antibiotic use (84.0%, IQR, 83–85%, n = 2). CPs collaborated with prescribers for infection control (54.7%, IQR 34.8–63.2%, n = 4) and for uncertain antibiotic treatment (77.0%, IQR 55.2–77.8%, n = 5). CPs educated patients (53.0%, IQR, 43.2–67.4%, n = 5) and screened guideline-compliance of antimicrobial prescriptions (47.5%, IQR, 25.2–58.3%, n = 3). Guidelines, training, interactions with prescribers, and reimbursement models were major barriers to CP-led AMS implementation. A limited number of validated survey tools are available to assess AMS perceptions and practices of CPs. AMS survey tools require further development to assess stewardship knowledge, stewardship targets, and implementation by CPs.
