Facilitators and barriers to implementing antimicrobial stewardship strategies: Results from a qualitative study

Pharmacist insights into antimicrobial stewardship: A social marketing approach

BACKGROUND

Antimicrobial resistance is a worldwide public health problem. Antimicrobial stewardship programs (ASPs) optimize antimicrobial use within hospitals. The social marketing framework has been used in analyzing systems and devising best practices.

OBJECTIVE

(s): To use the social marketing framework to explore pharmacist experiences and perceptions of structural, behavioral and interventional strategies that support ASPs.

METHODS

A qualitative approach utilizing semi-structured individual interviews was utilized. A purposive sample of hospital pharmacists was invited to participate. An interview guide was constructed to describe participant experience and perceptions regarding ASPs in their institutions based on elements of social marketing: Behavioral goals; Customer Insight; Segmentation and Targeting; Competition; Exchange; and Marketing and Interventional mix. Interviews were recorded digitally and transcribed verbatim. Thematic analysis was conducted using deductive methods. A combination of case-based and code-based approaches allowed individual and holistic analyses respectively. Codes were collated into themes and subthemes.

RESULTS

Saturation of themes occurred with 25 interviews from 17 hospitals. ASP metrics included: consumption of antibiotics using days of therapy and defined daily dose, rates of C. difficile and multidrug resistant organisms, resistance patterns, and provider adherence to the ASP. Active stewardship tools such as preauthorization, and prospective feedback/audit were preferred over passive tools such as order sets and automatic stop orders. A physician champion and a clinical pharmacist with infectious disease training were core elements in the multidisciplinary team. Despite certain areas being considered key for stewardship, participants emphasized a hospital-wide approach including outpatient departments; discharge stewardship emerged as a primary theme. Leadership supported ASPs with finances, rapid and novel diagnostics, Clinical Decision Support Systems, mobile technology, and continuous staff training.

CONCLUSIONS

The social marketing framework has been used to explore pharmacist perceptions that inform successful qualities including metrics, restriction methods, personnel, benefits, barriers, training needs/modes, and promotional avenues that support ASPs in hospitals.

Public hospital pharmacists' knowledge, attitudes, and practices for antibiotic stewardship implementation in Limpopo Province, South Africa

BACKGROUND

Hospital pharmacists are important in antibiotic stewardship programs (ASP), a global strategy to combat antibiotic resistance (ABR). South African public hospitals have limited ASP implementation. This study describes Limpopo Provincial Hospital pharmacists' knowledge, attitudes, and practice toward ASP implementation.

METHOD

A questionnaire to explore pharmacists' knowledge, attitudes and practices regarding ASP implementation comprised 43 questions hosted online. A link was sent by invitation e-mail to eligible respondents in November 2021. Five questions on respondents' demographics, 15 questions on ASP knowledge, 10 Likert scale questions on attitude, and 13 on ASP practices were included. Mean (standard deviation (SD)) knowledge and attitude scores and a median (interquartile range (IQR)) practice score was calculated. Associations between categorical variables were assessed using chi-square/Fisher's exact analysis (p < 0.05), with Cramér's V as effect size.

RESULTS

The survey yielded 35 responses (13.1%). Twenty (57.1%) respondents were female. Seventeen (48.6%) respondents were between the ages of 31 and 40 years. The mean knowledge score of respondents was 9.8 (2.6) (N = 34), with knowledge gaps on One Health and socioeconomic determinates of ABR. Ten (29.6%) respondents thought One Health discouraged multi-sector collaboration, and nineteen (55.9%) respondents thought ASP was the only strategic response to ABR. Sixteen (47.1%) respondents did not know that poor access to clean water accelerates ABR and seventeen (50.0%) did not know that poverty could be a determinant for antibiotic use. The mean respondent attitude score was 8.0 (1.7) (N = 28). Twenty-seven (96.4%) respondents agreed that ASP was necessary and agreed to participate in ASP respectively. All 28 (100.0%) respondents agreed to lead an ASP. The median (IQR) respondents' practice score was - 2.0 (IQR: -6.0-5.8) (N = 16). Respondents were inconsistently (never, sometimes, every time) participating in multi-disciplinary forums (6/16, 37.5%) and expressed a desire for training (11/13, 84.6%) on ASP through in-service (7/27, 25.9%). Respondents thought ASP training should include medical officers (12/29, 41.4%) and nurses (9/29, 31.8%). Knowledge score was associated with gender (p = 0.048; V = 0.416) and attitude score (p = 0.013; V = 0.556).

CONCLUSION

Our study found pharmacists had good knowledge and a positive attitude toward ASP implementation but poor ASP practices. A multi-disciplinary in-service training could address identified knowledge and practice gaps.

What Is Left to Tackle in Inpatient Antimicrobial Stewardship Practice and Research

Despite widespread uptake of antimicrobial stewardship in acute care hospitals, there is ongoing need for innovation and optimization of ASPs. This article discusses current antimicrobial stewardship practice challenges and ways to improve current antimicrobial stewardship workflows. Additionally, we propose new workflows that further engage front line clinicians in optimizing their own antibiotic decision making.

A qualitative evaluation of frontline clinician perspectives toward antibiotic stewardship programs

OBJECTIVE

To examine the perspectives of caregivers that are not part of the antibiotic stewardship program (ASP) leadership team (eg, physicians, nurses, and clinical pharmacists), but who interact with ASPs in their role as frontline healthcare workers.

DESIGN

Qualitative semistructured interviews.

SETTING

The study was conducted in 2 large national healthcare systems including 7 hospitals in the Veterans' Health Administration and 4 hospitals in Intermountain Healthcare.

PARTICIPANTS

We interviewed 157 participants. The current analysis includes 123 nonsteward clinicians: 47 physicians, 26 pharmacists, 29 nurses, and 21 hospital leaders.

METHODS

Interviewers utilized a semistructured interview guide based on the Consolidated Framework for Implementation Research (CFIR), which was tailored to the participant's role in the hospital as it related to ASPs. Qualitative analysis was conducted using a codebook based on the CFIR.

RESULTS

We identified 4 primary perspectives regarding ASPs. (1) Non-ASP pharmacists considered antibiotic stewardship activities to be a high priority despite the added burden to work duties: (2) Nurses acknowledged limited understanding of ASP activities or involvement with these programs; (3) Physicians criticized ASPs for their restrictions on clinical autonomy and questioned the ability of antibiotic stewards to make recommendations without the full clinical picture; And (4) hospital leaders expressed support for ASPs and recognized the unique challenges faced by non-ASP clinical staff.

CONCLUSION

Further understanding these differing perspectives of ASP implementation will inform possible ways to improve ASP implementation across clinical roles.

The use of telehealth-supported stewardship activities in acute-care and long-term care settings: An implementation effectiveness trial

BACKGROUND

We assessed the implementation of telehealth-supported stewardship activities in acute-care units and long-term care (LTC) units in Veterans' Administration medical centers (VAMCs).

DESIGN

Before-and-after, quasi-experimental implementation effectiveness study with a baseline period (2019-2020) and an intervention period (2021).

SETTING

The study was conducted in 3 VAMCs without onsite infectious disease (ID) support.

PARTICIPANTS

The study included inpatient providers at participating sites who prescribe antibiotics.

INTERVENTION

During 2021, an ID physician met virtually 3 times per week with the stewardship pharmacist at each participating VAMC to review patients on antibiotics in acute-care units and LTC units. Real-time feedback on prescribing antibiotics was given to providers. Additional implementation strategies included stakeholder engagement, education, and quality monitoring.

METHODS

The reach-effectiveness-adoption-implementation-maintenance (RE-AIM) framework was used for program evaluation. The primary outcome of effectiveness was antibiotic days of therapy (DOT) per 1,000 days present aggregated across all 3 sites. An interrupted time-series analysis was performed to compare this rate during the intervention and baseline periods. Electronic surveys, periodic reflections, and semistructured interviews were used to assess other RE-AIM outcomes.

RESULTS

The telehealth program reviewed 502 unique patients and made 681 recommendations to 24 providers; 77% of recommendations were accepted. After program initiation, antibiotic DOT immediately decreased in the LTC units (-30%; P < .01) without a significant immediate change in the acute-care units (+16%; P = .22); thereafter DOT remained stable in both settings. Providers generally appreciated feedback and collaborative discussions.

CONCLUSIONS

The implementation of our telehealth program was associated with reductions in antibiotic use in the LTC units but not in the smaller acute-care units. Overall, providers perceived the intervention as acceptable. Wider implementation of telehealth-supported stewardship activities may achieve reductions in antibiotic use.

Antimicrobial Stewardship and Pandemic Preparedness: Harnessing Lessons Learned to Advance Our Mission

Antimicrobial stewardship programs (ASPs) demonstrated poise and resilience in assisting with COVID-19 efforts across the globe, harnessing expertise in diagnostic stewardship, therapeutics, protocol development, and use of technology to rapidly expand their scope through strategic collaborations, dissemination of content expertise, and numerous contributions to the body of knowledge on COVID-19. Lessons learned from pandemic response should be used to advance the mission of ASPs and secure a "seat at the table" as health systems continue to expand and adapt to future public health crises.

Principles and Practice of Antimicrobial Stewardship Program Resource Allocation

Antimicrobial Stewardship Programs (ASP) improve individual patient outcomes and clinical care processes while reducing antimicrobial-associated adverse events, optimizing operational priorities, and providing institutional cost savings. ASP composition, resources required, and priority focuses are influenced by myriad factors. Despite robust evidence and broad national support, individual ASPs still face challenges in obtaining appropriate resources. Though understanding the current landscape of ASP resource allocation, factors influencing staffing needs, and strategies required to obtain desired resources is important, acceptance of recommended staffing levels and appropriate ASP resource allocation are much needed to facilitate ASP sustainability and growth across the complex and diverse health care continuum.

Skills, Not Just Knowledge: Infectious Diseases Fellows' Recommendations Regarding Antimicrobial Stewardship Training

BACKGROUND

Antimicrobial stewardship (AS) is an important topic in infectious diseases (ID) training, yet many ID fellowships lack formal training, and little is known about fellows' learning preferences.

METHODS

We conducted 24 in-depth interviews with ID fellows across the United States during 2018 and 2019 to explore their experiences with and preferences for AS education during fellowship. Interviews were transcribed, deidentified, and analyzed to identify themes.

RESULTS

Fellows had variable exposure to AS before and during fellowship, which impacted their knowledge about and attitude toward stewardship as a career; however, all fellows expressed the importance of learning general stewardship principles during fellowship. Some fellows' training included mandatory stewardship lectures and/or rotations, but most fellows felt their primary stewardship learning occurred through informal experiences in the clinical setting, such as holding the antimicrobial approval pager. Fellows expressed a preference for a standardized, structured curriculum that included in-person practical, interactive discussions with multidisciplinary faculty along with the opportunity to practice and apply their skills; however, they emphasized that time needed to be set aside for those educational activities. Although they wanted to learn the evidence and rationale for stewardship recommendations, they especially wanted training in and feedback on how to communicate stewardship recommendations to other health professionals, particularly in the setting of conflict.

CONCLUSIONS

ID fellows believe that standardized AS curricula should be included in their fellowship training, and they prefer structured, practical, and interactive learning experiences.

Impact of prolonged carbapenem use-focused antimicrobial stewardship on antimicrobial consumption and factors affecting acceptance of recommendations: a quasi-experimental study

This study aimed to assess the impact of a prolonged carbapenem use-focused antimicrobial stewardship program (ASP) on antimicrobial consumption and clinical outcomes and to analyze factors affecting adherence to interventions. Patients prescribed carbapenems for ≥ 2 weeks received intervention. Interrupted time-series analysis was performed to compare antimicrobial consumption before and after intervention. Factors associated with non-adherence to intervention were investigated. Of 273 patients who were eligible for intervention, discontinuation or de-escalation was recommended in 256 (94.1%) and intervention was accepted in 136 (53.1%) patients. Before intervention, carbapenem consumption significantly increased to 1.14 days of therapy (DOT)/1000 patient days (PD)/month (P = 0.018). However, it significantly declined by - 2.01 DOT/1000 PD/month without an increase in other antibiotic consumption (P < 0.001). Factors affecting non-adherence to intervention were younger age (odds ratio [OR] = 0.98; 95% confidence interval [CI] 0.96-1.00), solid organ malignancy (OR = 2.53, 95% CI 1.16-5.50), and pneumonia (OR = 2.59, 95% CI 1.08-6.17). However, ASP intervention was not associated with clinical outcomes such as length of hospital stay or mortality. Prolonged carbapenem prescription-focused ASP significantly reduced carbapenem consumption without adverse outcomes. Non-adherence to interventions was attributed more to prescriber-related factors, such as attitude, than patient-related factors including clinical severity.

Cultures of antibiotic prescribing in medical intensive care

Antimicrobial resistance (AMR) continues to present a challenge to international healthcare systems and structures of public health. The focus on optimizing antibiotic prescribing in human populations has challenged healthcare systems charged with making responsible their physician-prescribers. In the United States, physicians in almost every specialty and role use antibiotics as part of their therapeutic armamentariums. In United States hospitals, most patients are administered antibiotics during their stay. Therefore, antibiotic prescribing and utilization is a commonly accepted part of medical practice. In this paper, we utilize social science work on antibiotic prescribing to examine a critical space of care in United States hospital settings. From March to August 2018, we used ethnographic methods to study hospital-based medical intensive care unit physicians at the offices and hospital floors they frequent in two urban United States teaching hospitals. We focused on eliciting the interactions and discussions surrounding antibiotic decision-making that are uniquely influenced by the context of medical intensive care units. We argue that antibiotic use in the medical intensive care units under study was shaped by urgency, hierarchy, and uncertainty representative of the medical intensive care unit's role within the larger hospital system. We conclude that by studying the culture of antibiotic prescribing in medical intensive care units, we can see more clearly both the vulnerability of the looming antimicrobial resistance crisis and by contrast the perceived insignificance of stewarding antibiotic use when considered alongside the fragility of life amidst acute medical concerns regularly experienced in the unit.

Facilitators and barriers to implementing antimicrobial stewardship programs in public South African hospitals

Objective

The South African National Department of Health released guidelines and recommendations for antimicrobial stewardship (AMS) programs to be established in public healthcare facilities. Their implementation remains challenged, especially in North West Province, where the public health system functions under severe strain. This research explored and interpreted the facilitators that strengthen and barriers that hinder the implementation of the national AMS program in public hospitals in North West Province.

Design

A qualitative design and interpretive descriptive approach enabled insight into the realities of AMS program implementation.

Setting

Public hospitals in North West Province, sampled through criterion sampling (n = 5).

Participants

Purposive criterion sampling of healthcare practitioners (n = 30) actively participating in AMS programs in the 5 sampled public hospitals.

Method

Qualitative, interpretive description with semi-structured individual interviews that were digitally recorded and transcribed. The ATLAS.ti version 8 software facilitated content analysis, followed by second-level analysis.

Results

In total, 4 themes, 13 categories, and 25 subcategories emerged. We detected dissonance between government AMS ideals and the realities of AMS program implementation in public hospitals. A multilevel AMS leadership and governance vacuum exists in a dysfunctional health ecosystem in which AMS must operate. Healthcare practitioners agreed on the importance of AMS despite different understandings of AMS and ineffective multidisciplinary teams. Discipline-specific education and training are essential for all AMS participants.

Conclusions

AMS is essential yet complex, and its contextualization and implementation are underestimated in public hospitals. Recommendations are focused on a supportive organizational culture, contextualized AMS program implementation plans, and changes in management.

Perspectives on Antibiotic Stewardship Programs among Health Care Providers at Two University Hospitals in Egypt

The perspectives of healthcare professionals on antibiotic stewardship programs (ASPs) should be explored. Any antibiotic stewardship strategy must be individualized based on patient needs, prescription habits, and local resources. The current study aimed to explore the perspectives of healthcare providers on antibiotics stewardship and their awareness of these perspectives. Furthermore, potential barriers to the application of ASPs should be identified and addressed. This exploratory cross-sectional study utilized a qualitative method to evaluate critical care physicians, pediatricians, and clinical pharmacists (n = 43). The mean age of the physicians was 32 ± 1.5 years. Among them, approximately two-thirds (66%) were women. A thematic content analysis was performed to examine the responses of the participants and to prioritize the recommendations for and barriers to the implementation of ASPs from the perspective of healthcare providers. According to the interviewees, the primary obstacles include lack of time in implementation and monitoring and lack of awareness of the need for ASPs. All respondents recommended the implementation of supervised and continuous trainings. In conclusion, the abovementioned barriers must be adequately addressed to facilitate the implementation of ASPs.

A questionnaire based survey among pharmacy practitioners to evaluate the level of knowledge and confidence towards antimicrobial stewardship

Objective

Our study aimed to assess the knowledge, understanding and confidence of the practicing pharmacists in UAE as an antimicrobial Stewards. Antimicrobial resistance threatens the achievements of modern medicine globally, and it's highly required for the AMS principles to be implemented in our communities.

Methods

A cross-sectional online- questionnaire based survey was used among UAE pharmacy practitioners from different areas of practice who are holding pharmaceutical degrees and/or licensed pharmacists. The questionnaire was sent to the participants via social media platforms. The questionnaire was validated, and reliability assessment was made prior to the conduct.

Results

A total of 117 pharmacists responded to this study, out of which (70.9%, n=83) were females. Pharmacists which are from various practice fields participated in the survey, but the majority were pharmacists in Hospital pharmacies or Clinical pharmacists (47%, n=55), also community pharmacists (35.9%, n=42), while only (16.9%, n=20) ware from other areas of pharmacy including industrial pharmacy and academia. The majority of participants 88.9% (n= 104) were interested in pursuing their career as an Infectious disease pharmacist or getting a certificate in antimicrobial stewardship. The mean scores in the knowledge towards antimicrobial resistance was 3.75 (poor: 1-1.6, moderate: 1.7-3.3.

Good

3.4-5), indicates that the pharmacists have a good level of knowledge towards AMR. A total of 84.3% of participants succeeded in Identifying the correct intervention for antibiotic resistance. The findings also showed that the total mean score of hospital pharmacists (mean=10.6±1.12), and the average of the scores of community pharmacists (mean=9.8±1.38), were non-significant between the different area of practice. 52.3% of the participants had a training on antimicrobial stewardship during their experiential rotation which reflected on their confidence in their performance and knowledge assessment (p value < 0.05).

Conclusion

The study concluded good knowledge and high confidence levels among practicing pharmacists in UAE. However, the findings also identify areas of improvement in the practicing pharmacist, and the significant relationship between the knowledge and confidence scores reflects the ability of the practicing pharmacists to integrate the AMS principles within the UAE, which aligns with the attainability of the improvement.

Community pharmacists as antimicrobial guardians and gatekeepers - A qualitative study of the perspectives of pharmacy sector stakeholders

Background

Community pharmacists, as primary care providers, are an underutilised resource in antimicrobial stewardship (AMS). Primary care plays an important role in tackling antimicrobial resistance (AMR) as the principle of balancing access to antimicrobials while ensuring optimal use is agnostic to health setting. Understanding the sector's perceptions and practices towards AMS involvement is a continuing focus area of research. However, there is an opportunity to understand the sociological factors which influence the profession's contribution to stewardship practice, particularly across a broader spectrum of sector stakeholders at the individual, practice, system, and policy levels.

Objective

To explore stakeholders' perceptions of the Australian community pharmacy sector's AMS involvement.

Methods

Semi-structured interviews were conducted with fifteen key informants from the Australian community pharmacy sector. Participants' insights were invited across three broad areas: (1) understanding of AMR and AMS; and the (2) current and (3) future state of community pharmacy's AMS involvement. Interviews were audio-recorded, transcribed verbatim and analyzed using a combined method of inductive (informed by the Theoretical Domains Framework) and deductive thematic analysis.

Results

Perceptions on promoting community pharmacists' AMS involvement within their existing role in promoting the quality use of medicines were heard. Adopting an antimicrobial guardian or gatekeeper role was perceived as influenced by the timing of their interaction with a patient either prior to, or post-consultation with a general practitioner (GP). Suggestions that the profession's potential and actual role in AMS could be challenged or even delimited due to lack of access to completeness of clinical information, and perceived consequences from a clinical and professional engagement perspective were also heard.

Conclusion

Collaborative partnerships between GPs and community pharmacists, framing stewardship within a quality use of medicines agenda, and highlighting connections between pharmacists' professional services such as minor ailments are key elements enabling community pharmacist's antimicrobial gatekeeper and guardian role.

Current Status of Antibiotic Stewardship and the Role of Biomarkers in Antibiotic Stewardship Programs

The importance of antibiotic stewardship is increasingly emphasized in accordance with the increasing incidences of multidrug-resistant organisms and accompanying increases in disease burden. This review describes the obstacles in operating an antibiotic stewardship program (ASP), and whether the use of biomarkers within currently available resources can help. Surveys conducted around the world have shown that major obstacles to ASPs are shortages of time and personnel, lack of appropriate compensation for ASP operation, and lack of guidelines or appropriate manuals. Sufficient investment, such as the provision of full-time equivalent ASP practitioners, and adoption of computerized clinical decision systems are useful measures to improve ASP within an institution. However, these methods are not easy in terms of both time commitments and cost. Some biomarkers, such as C-reactive protein, procalcitonin, and presepsin are promising tools in ASP due to their utility in diagnosis and forecasting the prognosis of sepsis. Recent studies have demonstrated the usefulness of algorithmic approaches based on procalcitonin level to determine the initiation or discontinuation of antibiotics, which would be helpful in decreasing antibiotics use, resulting in more appropriate antibiotics use.

Development of an international survey tool to measure confidence and current antimicrobial stewardship practices of hospital pharmacists

BACKGROUND

Pharmacists are identified as key members of hospital antimicrobial stewardship (AMS) teams in international guidelines. Developing an international standardized tool to measure hospital pharmacists' confidence and practices of AMS will encourage knowledge sharing and better networking between hospital pharmacists internationally.

OBJECTIVES

To develop a survey tool that can be used internationally to assess pharmacists' knowledge, confidence, perceived barriers and current AMS practices.

METHODS

A project team was formed to refine the survey tool that was initially used in a previous survey study. Following revision by the project team, a revised survey tool was sent to the ESCMID Study Group for Antimicrobial Stewardship (ESGAP). Feedback from the ESGAP members was considered by the project team to finalize the survey tool.

RESULTS

A total of 88 changes were made to the survey tool after revision by the project team. A total of 43/216 (19.9%) of ESGAP members provided feedback on the survey tool, which led to a further 19 revisions. ESGAP members were agreeable to the questions in the survey tool, with >50% agreeing that each question was suitable. The final survey tool consisted of 42 questions, reduced from 72 questions in the original survey.

CONCLUSIONS

An international survey tool to measure hospital pharmacists' confidence and practices of AMS was developed. This tool will help the wider hospital pharmacy community in conducting local studies on current AMS practices and to identify areas where further support is needed. Use of a standardized survey tool will also allow individual regions/countries to compare their data with other countries to identify potential quality improvement programmes.

Clinicians' Intention to Submit Microbiological Pathogenic Test Before Antibiotics Use and Its Influencing Factors: New Evidence from the Perspective of Hospital Management

Purpose

Antimicrobial resistance (AR) is a global public health problem, improving clinicians’ intention to submit microbiological pathogenic test (submission intention) can effectively increase the value for rational use antibiotics to curb AR. However, there are few studies on the factors influencing improvement of the submission intention, especially from the perspective of hospital management. This study will fill the gap and provide evidence that can continuously support improvement of antibiotics prescribing rationally.

Patients and Methods

A cross-sectional survey of clinicians was conducted in all public hospitals in Hubei, China. Dependent variables were submission intention of non-restricted-use, restricted-use and special-use antibiotics which were measured submission, not sure submission, no submission. Independent variables were frequency of training and publicity on submission, and hospital with or without submission performance assessment, guideline, information decision system and laboratory items, including bacterial culture item, fungal culture item and so on. Clinicians’ demographics were applied as control variables. Multinomial logistic regression was performed to model independent variables influencing submission intention.

Results

For non-restricted-use antibiotics, guideline (OR = 0.263; 95% CI = [0.188, 0.369]) (OR = 0.526; 95% CI = [0.375, 0.738]) and bacterial culture item (OR = 0.141; 95% CI = [0.074, 0.268]) (OR = 0.520; 95% CI = [0.292, 0.927]) are key factors that positively affect clinicians’ intention on submission and not sure submission; For restricted-use and special-use antibiotics, training frequency and bacterial culture item (OR = 0.155; 95% CI = [0.076, 0.315]) (OR = 0.092; 95% CI = [0.036, 0.232]) (OR = 0.106; 95% CI = [0.046, 0.248]) (OR = 0.027; 95% CI = [0.006, 0.117]) are key factors that positively affect clinicians’ intention on submission and not sure submission.

Conclusion

This study found that bacterial culture item, guideline, and training frequency are key factors that affect clinicians’ intention on submission and not sure submission, but various factors exist different effects level on different types of antibiotics. Consequently, a focus should be placed on the construction and implementation of management factors, as well as reformation of antimicrobial stewardship in hospitals according to the types of antibiotics.

Improving the Development and Implementation of Audit and Feedback Systems to Support Health Care Workers in Limiting Antimicrobial Resistance in the Hospital: Scoping Review

Background

For eHealth technologies in general and audit and feedback (AF) systems specifically, integrating interdisciplinary theoretical underpinnings is essential, as it increases the likelihood of achieving desired outcomes by ensuring a fit among eHealth technology, stakeholders, and their context. In addition, reporting on the development and implementation process of AF systems, including substantiations of choices, enables the identification of best practices and accumulation of knowledge across studies but is often not elaborated on in publications.

Objective

This scoping review aims to provide insights into the development and implementation strategies for AF systems for a real-world problem that threatens modern health care—antimicrobial resistance—and provide an interdisciplinary conceptual framework that can serve as a checklist and guidance for making informed choices in the development and implementation of future AF systems.

Methods

A scoping review was conducted by querying PubMed, Scopus, Web of Science, IEEE Xplore Digital Library, and Embase (≥2010) for studies describing either the development or implementation process, or both, of an AF system for antimicrobial resistance or infections in hospitals. Studies reporting only on effectiveness or impact were excluded. A total of 3 independent reviewers performed the study selection, and 2 reviewers constructed the conceptual framework through the axial and selective coding of often-used theories, models, and frameworks (TMFs) from the literature on AF and eHealth development and implementation. Subsequently, the conceptual framework was used for the systematic extraction and interpretation of the studies’ descriptions of AF systems and their development and implementation.

Results

The search resulted in 2125 studies that were screened for eligibility, of which 12 (0.56%); 2012-2020) were included. These studies described the development and implementation processes heterogeneously in terms of study aims, study targets, target groups, methods, and theoretical underpinnings. Few studies have explicitly explained how choices for the development and implementation of AF systems were substantiated by the TMFs. The conceptual framework provided insights into what is reported on the development and implementation process and revealed underreported AF system constructs (eg, AF system design; engagement with the AF system; and comparison, goal setting, and action planning) and development and implementation (eg, champions) constructs.

Conclusions

This scoping review showed the current heterogeneous reporting of AF systems and their development and implementation processes and exemplified how interdisciplinary TMFs can (and should) be balanced in a conceptual framework to capture relevant AF systems and development and implementation constructs. Thereby, it provides a concrete checklist and overall guidance that supports the professionalization and harmonization of AF system development and implementation. For the development and implementation of future AF systems and other eHealth technologies, researchers and health care workers should be supported in selecting and integrating TMFs into their development and implementation process and encouraged to explicitly report on theoretical underpinnings and the substantiation of choices.

What influences the implementation and sustainability of antibiotic stewardship programmes in hospitals? A qualitative study of antibiotic pharmacists' perspectives across South West England

OBJECTIVES

Antibiotic stewardship programmes (ASPs) are needed at every hospital as they can improve antibiotic use and address antibiotic resistance. Pharmacists are key agents and specialists in these programmes. This study explored antibiotic pharmacists' perceptions of factors that influence the implementation and sustainability of hospital-based ASPs.

METHODS

Semistructured interviews were conducted with hospital antibiotic pharmacists face-to-face or by telephone. NVivo V.12 software was used to collate and organise the data grouped within codes. Thematic analysis was undertaken using inductive and deductive approaches to produce overarching themes.

RESULTS

Thirteen pharmacists from 13 hospitals were interviewed. Four main themes were identified: (1) 'organisational culture' which highlighted the importance of strong local clinical leadership to help achieve organisational buy-in and address resistance among physicians or clinical hierarchies; (2) 'national influences' including networks, guidance and incentive schemes which were considered to be a driver to bring about changes across organisation; (3) 'continuous monitoring with feedback ASP data, preferably through direct communication' to demonstrate the impact of the programmes which then facilitated ongoing support from local leadership and improved engagement across organisation; and (4) 'resources' which indicated the need of information technology and dedicated personnel with protected time to support ASP activities.

CONCLUSIONS

Interventions and strategies should operate at different levels-individual, team, organisational and national-to help implement and sustain ASPs in hospital. This is also the first study to identify and highlight the importance of national initiatives in contributing to the implementation and sustainability of hospital-based ASPs.

Pharmacists’ Perspectives of Their Roles in Antimicrobial Stewardship: A Qualitative Study among Hospital Pharmacists in Malaysia

Antimicrobial resistance has negatively impacted patient outcomes and increased healthcare costs. Antimicrobial stewardship (AMS) includes all activities and policies to promote the judicious use of antimicrobials. Pharmacists are key players in AMS models worldwide. However, there is a research gap in the role of pharmacists as antimicrobial stewards in Malaysia. This study aimed to explore hospital pharmacists’ perspectives on their roles in, and barriers and facilitators to the implementation of AMS strategies. Individual, semi-structured interviews were conducted with 16 hospital pharmacists involved in AMS activities from 13 public hospitals in Kuala Lumpur and Selangor. Audio-taped interviews were transcribed verbatim and imported into NVivo software version 10.0 (QSR). A thematic analysis method was used to identify themes from the qualitative data until theme saturation was reached. Respondents perceived pharmacists as having important roles in the implementation of AMS strategies, in view of the multiple tasks they were entrusted with. They described their functions as antimicrobial advisors, antimicrobial guardians and liaison personnel. The lack of resources in terms of training, manpower and facilities, as well as attitudinal challenges, were some barriers identified by the respondents. Administrative support, commitment and perseverance were found to be facilitators to the role of pharmacists in AMS. In conclusion, pharmacists in public hospitals play important roles in AMS teams. This study has provided insights into the support that AMS pharmacists in public hospitals require to overcome the barriers they face and to enhance their roles in the implementation of AMS strategies.

The feasibility of implementing antibiotic restrictions for fluoroquinolones and cephalosporins: a mixed-methods study across 15 Veterans Health Administration hospitals

INTRODUCTION

The optimal method for implementing hospital-level restrictions for antibiotics that carry a high risk of Clostridioides difficile infection has not been identified. We aimed to explore barriers and facilitators to implementing restrictions for fluoroquinolones and third/fourth-generation cephalosporins.

METHODS

This mixed-methods study across a purposeful sample of 15 acute-care, geographically dispersed Veterans Health Administration hospitals included electronic surveys and semi-structured interviews (September 2018 to May 2019). Surveys on stewardship strategies were administered at each hospital and summarized with descriptive statistics. Interviews were performed with 30 antibiotic stewardship programme (ASP) champions across all 15 sites and 19 additional stakeholders at a subset of 5 sites; transcripts were analysed using thematic content analysis.

RESULTS

The most restricted agent was moxifloxacin, which was restricted at 12 (80%) sites. None of the 15 hospitals restricted ceftriaxone. Interviews identified differing opinions on the feasibility of restricting third/fourth-generation cephalosporins and fluoroquinolones. Some participants felt that restrictions could be implemented in a way that was not burdensome to clinicians and did not interfere with timely antibiotic administration. Others expressed concerns about restricting these agents, particularly through prior approval, given their frequent use, the difficulty of enforcing restrictions and potential unintended consequences of steering clinicians towards non-restricted antibiotics. A variety of stewardship strategies were perceived to be effective at reducing the use of these agents.

CONCLUSIONS

Across 15 hospitals, there were differing opinions on the feasibility of implementing antibiotic restrictions for third/fourth-generation cephalosporins and fluoroquinolones. While the perceived barrier to implementing restrictions was frequently high, many hospitals were effectively using restrictions and reported few barriers to their use.

Factors affecting physician implementation of hospital pharmacists' medication appropriateness recommendations in older adults

AIMS

Non-implementation of pharmacist recommendations by physician prescribers may prolong potentially inappropriate prescribing in hospitalised older adults, increasing the risk of adverse clinical outcomes. The aim of this study was to ascertain the key factors affecting physician prescriber implementation of pharmacists' medication appropriateness recommendations in hospitalised older adults.

METHODS

Semi-structured interviews were conducted with hospital pharmacists and physicians who provided care to older adults (≥65 years) in 2 acute university teaching hospitals in Ireland. Content analysis was employed to identify the key themes that influence physician prescriber implementation of pharmacist recommendations.

RESULTS

Fourteen interviews were conducted with 6 hospital pharmacists and 8 hospital physicians between August 2018 and August 2019. Five key factors were found to affect physician implementation of pharmacist recommendations: (i) the clinical relevance and complexity of the recommendation-recommendations of higher priority and those that do not require complex decision-making are implemented more readily; (ii) interprofessional communication-recommendations provided verbally, particularly those communicated face to face with confidence and assertion, are more likely to be implemented than written recommendations; (iii) physician role and identity-the grade, specialty, and personality of the physician significantly affect implementation; (iv) knowing each other and developing trusting relationships-personal acquaintance and the development of interprofessional trust and rapport greatly facilitate recommendation implementation; and (v) the hospital environment-organisational issues such as documentation in the patient notes, having the opportunity to intervene, and the clinical pharmacy model all affect implementation.

CONCLUSION

This study provides a deeper understanding of the underlying behavioural determinants affecting physician prescriber implementation of pharmacist recommendations and will aid in the development of theoretically-informed interventions to improve medication appropriateness in hospitalised older adults.

Operationalising outpatient antimicrobial stewardship to reduce system-wide antibiotics for acute bronchitis

BACKGROUND

Antibiotics are not recommended for treatment of acute uncomplicated bronchitis (AUB), but are often prescribed (85% of AUB visits within the Veterans Affairs nationally). This quality improvement project aimed to decrease antibiotic prescribing for AUB in community-based outpatient centres from 65% to <32% by April 2020.

METHODS

From January to December 2018, community-based outpatient clinics' 6 months' average of prescribed antibiotics for AUB and upper respiratory infections was 63% (667 of 1054) and 64.6% (314 of 486) when reviewing the last 6 months. Seven plan-do-study-act (PDSA) cycles were implemented by an interprofessional antimicrobial stewardship team between January 2019 and March 2020. Balancing measures were a return patient phone call or visit within 4 weeks for the same complaint. Χ² tests and statistical process control charts using Western Electric rules were used to analyse intervention data.

RESULTS

The AUB antibiotic prescribing rate decreased from 64.6% (314 of 486) in the 6 months prior to the intervention to 36.8% (154 of 418) in the final 6 months of the intervention. No change was seen in balancing measures. The largest reduction in antibiotic prescribing was seen after implementation of PDSA 6 in which 14 high prescribers were identified and targeted for individualised reviews of encounters of patients with AUB with an antimicrobial steward.

CONCLUSIONS

Operational implementation of successful stewardship interventions is challenging and differs from the traditional implementation study environment. As a nascent outpatient stewardship programme with limited resources and no additional intervention funding, we successfully reduced antibiotic prescribing from 64.6% to 36.8%, a reduction of 43% from baseline. The most success was seen with targeted education of high prescribers.

Short-Duration Electronic Health Record Option Buttons to Reduce Prolonged Length of Antibiotic Therapy in Outpatients

BACKGROUND

Prolonged antibiotic therapy may be associated with increased adverse events and antibiotic resistance. We deployed an intervention in the electronic health record (EHR) to reduce antibiotic duration for pediatric outpatients.

METHODS

A preintervention and postintervention interrupted time series analysis of antibiotic duration for 7 antibiotics was performed for patients discharged from the ED and clinics of a children's hospital network from 2012 to 2018. In February 2015, clickable 5- and 7-day duration option buttons were deployed in the EHR for clindamycin, cephalexin, ciprofloxacin and levofloxacin, trimethoprim-sulfamethoxazole, amoxicillin, and cefdinir, with an additional 10-day option for the latter 2. Prescribers were able to enter a free-text duration. The option buttons were not announced, and were not linked to a specific diagnosis or quality improvement initiative. The primary outcome was proportion of prescriptions per month with duration of 10 days. Balancing secondary outcomes were reorders of the same agent, return to clinic, and inpatient admissions within 30 days.

RESULTS

There were 54 315 prescriptions for the 7 antibiotics associated with 39 894 patients, 18 683 clinic visits, and 35 632 ED visits. Overall, a -5.1% (95% confidence interval [CI], -8.3% to -2.0%) change in the proportion of prescriptions with a 10-day duration was attributable to the intervention, with larger effects noted for clindamycin (-20.8% [95% CI, -26.9% to -14.7%]) and cephalexin (-9.9% [95% CI, -14.3% to -5.4%]). There was no increase in the reorders of the same agent, return clinical encounters, or inpatient admissions within 30 days.

CONCLUSIONS

A simple intervention in the EHR can safely reduce duration of antibiotic therapy.

Antibiotic stewardship implementation at hospitals without on-site infectious disease specialists: A qualitative study

BACKGROUND

Hospitals are required to have antibiotic stewardship programs (ASPs), but there are few models for implementing ASPs without the support of an infectious disease (ID) specialist, defined as an ID physician and/or ID pharmacist.

OBJECTIVE

In this study, we sought to understand ASP implementation at hospitals that lack on-site ID support within the Veterans' Health Administration (VHA).

METHODS

Using a mandatory VHA survey, we identified acute-care hospitals that lacked an on-site ID specialist. We conducted semistructured interviews with personnel involved in ASP activities.

SETTING

The study was conducted across 7 VHA hospitals.

PARTICIPANTS

In total, 42 hospital personnel were enrolled in the study.

RESULTS

The primary responsibility for ASPs fell on the pharmacist champions, who were typically assigned multiple other non-ASP responsibilities. The pharmacist champions were more successful at gaining buy-in when they had established rapport with clinicians, but at some sites, the use of contract physicians and frequent staff turnover were potential barriers. Some sites felt that having access to an off-site ID specialist was important for overcoming institutional barriers and improving the acceptance of their stewardship recommendations. In general, stewardship champions struggled to mobilize institutional resources, which made it difficult to advance their programmatic goals.

CONCLUSION

In this study of 7 hospitals without on-site ID support, we found that ASPs are largely a pharmacy-driven process. Remote ID support, if available, was seen as helpful for implementing stewardship interventions. These findings may inform the future implementation of ASPs in settings lacking local ID expertise.

Perceived roles and barriers to nurses' engagement in antimicrobial stewardship: A Thai qualitative case study

BACKGROUND

Antimicrobial stewardship is the practice of ensuring the optimal use of antibiotics to prevent antimicrobial resistance. A multidisciplinary approach is considered best practice; however, little is known about nurses' contribution.

OBJECTIVES

To explore how organisational multidisciplinary leaders and clinical nurses perceive nurses' roles in AMS in a single organisational site case study based in Thailand, within the current governance, educational and practice context, and the barriers to nurses' engagement in AMS.

METHODS

A qualitative descriptive study using thematic analysis approach was conducted in a 1000-bed university hospital in Bangkok, Thailand. The combined number of organisational leaders and nurses was 33 including 15 individual organisational leader interviews and three focus groups involving 18 nurses.

RESULTS

Nurses currently participate in AMS by supporting system processes, monitoring safety and optimal antibiotic use and patient education. A lack of clear articulation of nurses' role and traditional professional hierarchies limits active participation. Inconsistent engagement was perceived as due to a failure to prioritise AMS activities, a lack of formal policies and a need for further education.

CONCLUSION

Nurses do engage in AMS but there are significant governance, hierarchical and educational impediments. These gaps need to be addressed before clearly defined nurse roles in AMS can be developed and embedded into clinical practice.

Antimicrobial stewardship in the outpatient parenteral antimicrobial therapy (OPAT) setting: the impact of prescription assessment by an infectious diseases specialist

Objective

In recent years, the use of outpatient parenteral antimicrobial therapy (OPAT) has increased, resulting in the need to ensure its rational and adequate utilization. This article describes the implementation of an antimicrobial stewardship program in the OPAT setting by a Health Maintenance Organization (HMO) and its results.

Method

An infectious disease (ID) physician made routine assessments of all home care parenteral antimicrobial requests from February to December 2019. Information on diagnosis, renal function, weight, previous antimicrobials, and microbiology were gathered during remote evaluations. Prescription changes recommended by the ID specialist were not mandatory, but implemented by the primary provider as accepted. Antibiotic consumption data was analyzed from January 2018 to December 2019. An active screening was conducted for treatment failures: two or more treatment course requirements, or death within 15 days of the evaluation were reexamined.

Results

A total of 506 antimicrobial requests were assessed. The most frequent diagnoses were urinary tract infection, pneumonia, and orthopedic surgical site infection. Six percent of evaluations were not completed due to insufficient information and 12% were requests by the primary physician for initial antimicrobial guidance. Of the 416 completed prescriptions evaluations, 58% had suggested changes, including different antimicrobials (40%), treatment duration (25%), and route of administration (23%). There was an increase in use of teicoplanin and meropenem, and a decrease in ceftriaxone, ertapenem, cefepime, amikacin and daptomycin use. The HMO’s overall parenteral antimicrobial outpatient consumption, which had shown an upward trend over the previous year, decreased after program initiation. No major adverse results were detected in patients’ clinical outcomes; two treatment failures were detected and promptly corrected; no deaths attributed to antibiotic changes were detected.

Conclusion

Outpatient antimicrobial stewardship, through remote assessment by an ID specialist, was effective and safe in the OPAT setting.

The state of antibiotic stewardship programs in 2021: The perspective of an experienced steward

Recognition of antibiotic stewardship programs (ASPs) as essential components of quality health care has dramatically increased in the past decade. The value of ASPs has been further reinforced during the coronavirus disease 2019 (COVID-19) pandemic because these programs were instrumental in monitoring antibiotic use, assessing emerging COVID-19 therapies, and coordinating implementation of monoclonal antibody infusions and vaccinations. ASPs are now required across hospital settings as a condition of participation for the Centers for Medicare and Medicaid Services and for accreditation by The Joint Commission. In the 2019 National Healthcare Safety Network annual survey, almost 89% of hospitals met the Seven Core Elements for ASPs defined by the Centers for Disease Control and Prevention. More than 61% of programs were co-led by physicians and pharmacists, evidence of the leadership role of both groups. ASPs employ many strategies to improve prescribing. Core interventions of preauthorization for targeted antibiotics, prospective audit and feedback, and development of local treatment guidelines have been supplemented with numerous emerging strategies. Diagnostic stewardship, optimizing duration of therapy, promoting appropriate conversion from intravenous to oral therapy, monitoring at transitions of care and hospital discharge, implementing stewardship initiatives in the outpatient setting, and increasing use of telemedicine are approaches being adopted across hospital settings. As a core function for medical facilities, ASP leaders must ensure that antibiotic use and ASP interventions promote optimal and equitable care. The urgency of success becomes progressively greater as complex patterns of antibiotic resistance continue to emerge, exacerbated by unpredictable factors such as a worldwide pandemic.

Survey of physician and pharmacist steward perceptions of their antibiotic stewardship programs

Objective:

To examine how individual steward characteristics (eg, steward role, sex, and specialized training) are associated with their views of antimicrobial stewardship program (ASP) implementation at their institution.

Design:

Descriptive survey from a mixed-methods study.

Setting:

Two large national healthcare systems; the Veterans’ Health Administration (VA) (n = 134 hospitals) and Intermountain Healthcare (IHC; n = 20 hospitals).

Participants:

We sent the survey to 329 antibiotic stewards serving in 154 hospitals; 152 were physicians and 177 were pharmacists. In total, 118 pharmacists and 64 physicians from 126 hospitals responded.

Methods:

The survey was grounded in constructs of the Consolidated Framework for Implementation Research, and it assessed stewards’ views on the development and implementation of antibiotic stewardship programs (ASPs) at their institutions We then examined differences in stewards’ views by demographic factors.

Results:

Regardless of individual factors, stewards agreed that the ASP added value to their institution and was advantageous to patient care. Stewards also reported high levels of collegiality and self-efficacy. Stewards who had specialized training or those volunteered for the role were less likely to think that the ASP was implemented due to a mandate. Similarly volunteers and those with specialized training felt that they had authority in the antibiotic decisions made in their facility.

Conclusions:

Given the importance of ASPs, it may be beneficial for healthcare institutions to recruit and train individuals with a true interest in stewardship.

Evidence for action: a One Health learning platform on interventions to tackle antimicrobial resistance

Improving evidence for action is crucial to tackle antimicrobial resistance. The number of interventions for antimicrobial resistance is increasing but current research has major limitations in terms of efforts, methods, scope, quality, and reporting. Moving the agenda forwards requires an improved understanding of the diversity of interventions, their feasibility and cost-benefit, the implementation factors that shape and underpin their effectiveness, and the ways in which individual interventions might interact synergistically or antagonistically to influence actions against antimicrobial resistance in different contexts. Within the efforts to strengthen the global governance of antimicrobial resistance, we advocate for the creation of an international One Health platform for online learning. The platform will synthesise the evidence for actions on antimicrobial resistance into a fully accessible database; generate new scientific insights into the design, implementation, evaluation, and reporting of the broad range of interventions relevant to addressing antimicrobial resistance; and ultimately contribute to the goal of building societal resilience to this central challenge of the 21st century.

"There is no one to pick up the pieces": Sustainability of antibiotic stewardship programs in nursing homes

OBJECTIVE

To describe nursing home staff experiences and perceptions of the factors that impact the sustainability of an antibiotic stewardship program (ASP).

METHODS

Using a qualitative descriptive design, semistructured interviews with staff at 9 not-for-profit nursing homes with an established ASP were conducted and audio recorded. De-identified transcriptions of the interviews were coded using a sustainability framework and were analyzed to identify themes.

RESULTS

Interviews were conducted with 48 clinical and administrative staff to elicit their perceptions of the ASPs, and 7 themes were identified. ASPs were perceived to be resource intensive and "data driven," requiring access to and interpretation of data that are not readily available at many nursing homes. Though motivated and committed, ASP champions felt that they could not single-handedly sustain the program. Attending to daily clinical needs (ie, "fires") made it hard to progress beyond implementation and to reach step 2 of sustainability. Longstanding treatment habits by external prescribers and regulations were believed to impede ASP efforts. Partnerships with an external consultant with antibiotic stewardship expertise were considered important, as was the need for internal leadership support and collaboration across disciplinary boundaries. Participants felt that consistent and ongoing education on antibiotic stewardship at all staff levels was important.

CONCLUSIONS

Although many interconnected factors impact the sustainability of an ASP, nursing homes may be able to sustain an ASP by focusing on 3 critical areas: (1) explicit support by nursing home leadership, (2) external partnerships with professionals with antibiotic stewardship expertise and internal interprofessional collaborations, and (3) consistent education and training for all staff.

Intervention planning for Antibiotic Review Kit (ARK): a digital and behavioural intervention to safely review and reduce antibiotic prescriptions in acute and general medicine

Background

Hospital antimicrobial stewardship strategies, such as ‘Start Smart, Then Focus’ in the UK, balance the need for prompt, effective antibiotic treatment with the need to limit antibiotic overuse using ‘review and revise’. However, only a minority of review decisions are to stop antibiotics. Research suggests that this is due to both behavioural and organizational factors.

Objectives

To develop and optimize the Antibiotic Review Kit (ARK) intervention. ARK is a complex digital, organizational and behavioural intervention that supports implementation of ‘review and revise’ to help healthcare professionals safely stop unnecessary antibiotics.

Methods

A theory-, evidence- and person-based approach was used to develop and optimize ARK and its implementation. This was done through iterative stakeholder consultation and in-depth qualitative research with doctors, nurses and pharmacists in UK hospitals. Barriers to and facilitators of the intervention and its implementation, and ways to address them, were identified and then used to inform the intervention’s development.

Results

A key barrier to stopping antibiotics was reportedly a lack of information about the original prescriber’s rationale for and their degree of certainty about the need for antibiotics. An integral component of ARK was the development and optimization of a Decision Aid and its implementation to increase transparency around initial prescribing decisions.

Conclusions

The key output of this research is a digital and behavioural intervention targeting important barriers to stopping antibiotics at review (see http://bsac-vle.com/ark-the-antibiotic-review-kit/ and http://antibioticreviewkit.org.uk/). ARK will be evaluated in a feasibility study and, if successful, a stepped-wedge cluster-randomized controlled trial at acute hospitals across the NHS.

Evaluation of a successful fluoroquinolone restriction intervention among high-risk patients: A mixed-methods study

Objective

We conducted a quality improvement initiative to restrict fluoroquinolone prescribing on two inpatient units housing high-risk patients and applied a human factors approach to understanding the barriers and facilitators to success of this intervention by front-line providers.

Methods

This was a mixed-methods, quasi-experimental study. This study was conducted on two inpatient units at a tertiary care academic medical center: the medical-surgical intensive care and abdominal solid organ transplant units. Unit-level data were collected retrospectively for 24 months pre- and post- fluoroquinolone restriction intervention, implemented in July 2016, for all admissions to the study units. Our restriction intervention required antimicrobial stewardship pre-approval for fluoroquinolone prescribing. We explored barriers and facilitators to optimal fluoroquinolone prescribing using semi-structured interviews attending, fellow and resident physicians, advanced practice providers and pharmacists on these units.

Results

Hospital-onset C. difficile infection did not decrease significantly, but fluoroquinolone use declined significantly from 111.6 to 19.8 days of therapy per 1000 patient-days without negatively impacting length of stay, readmissions or mortality. Third generation cephalosporin and aminoglycoside use increased post-restriction. Providers identified our institution’s strong antimicrobial stewardship program and pharmacy involvement in antimicrobial decision making as key facilitators of fluoroquinolone optimization and patient complexity, lack of provider education and organizational culture as barriers to optimal prescribing.

Conclusions

Fluoroquinolones can be safely restricted even among high-risk patients without negatively impacting length of stay, readmissions or mortality. Our study provides a framework for successful antimicrobial stewardship interventions informed by perceptions of front line providers.

Prescribers' experience and opinions on antimicrobial stewardship programmes in hospitals: a French nationwide survey

OBJECTIVES

To assess prescribers' experiences and opinions regarding antimicrobial stewardship programme (ASP) activities.

METHODS

A cross-sectional paper-based survey was conducted among prescribers in 27 out of 35 randomly selected large hospitals in France.

RESULTS

All 27 investigated hospitals (20 non-university public, 4 university-affiliated and 3 private hospitals) had an ASP and an appointed antibiotic advisor (AA), with a median of 0.9 full-time equivalents per 1000 acute-care beds (IQR 0-1.4). Of the 1963 distributed questionnaires, 920 were completed (46.9%). Respondents were mainly attending physicians (658/918, 71.7%) and medical specialists (532/868, 61.3%). Prescribers identified two main ASP objectives: to limit the spread of resistance (710/913, 77.8%) and to improve patient care and prognosis (695/913, 76.1%). The presence of an AA constituted a core element of ASP (96.2% agreement between answers of ASP leader and respondents). Respondents acknowledged an AA's usefulness especially on therapeutic issues, i.e. choosing appropriate antibiotic (agreement 84.7%) or adapting treatment (89.6%), but less so on diagnostic issues (31.4%). Very few respondents reported unsolicited counselling and post-prescription controls. Three-quarters of prescribers identified local guidelines (692/918, 75.4%). Prescribers did not approve of measures counteracting their autonomy, i.e. automatic stop orders (agreement 23.4%) or pre-approval by AAs (28.8%). They agreed more with educational interventions (73.0%) and clinical staff meetings (70.0%).

CONCLUSIONS

Prescribers perceived ASP mainly through its 'on-demand' counselling activities. They preferred measures that did not challenge their clinical autonomy. High levels of antibiotic consumption in French hospitals bring into question the effectiveness of such an approach. However, limited ASP staffing and resources may preclude extended activities.

Perspectives of Physician and Pharmacist Stewards on Successful Antibiotic Stewardship Program Implementation: A Qualitative Study

Background

Antibiotic stewardship programs (ASPs) are required at every hospital regardless of size. We conducted a qualitative study across different hospital settings to examine perspectives of physician and pharmacist stewards about the dynamics within their team and contextual factors that facilitate the success of their programs.

Methods

Semistructured interviews were conducted in March-November 2018 with 46 ASP stewards, 30 pharmacists, and 16 physicians, from 39 hospitals within 2 large hospital systems.

Results

We identified 5 major themes: antibiotic stewards were enthusiastic about their role, committed to the goals of stewardship for their patients and as a public-health imperative, and energized by successful interventions; responsibilities of pharmacist and physician stewards are markedly different, and pharmacy stewards performed the majority of the day-to-day stewardship work; collaborative teamwork is important to improving care, the pharmacists and physicians supported each other, and pharmacists believed that having a strong physician leader was essential; provider engagement strategies are a critical component of stewardship, and recommendations must be communicated in a collegial manner that did not judge the provider competence, preferably through face-to-face interactions; and hospital leadership support for ASP goals and for protected time for ASP activities is critical for success.

Conclusions

The physician-pharmacist team is essential for ASPs; most have pharmacists leading and performing day-to-day activities with physician support. Collaborative, persuasive approaches for ASP interventions were the norm. Stewards were careful not to criticize or judge inappropriate antibiotic prescribing. Further research should examine whether this persuasive approach undercuts provider appreciation of stewardship as a public health mandate.

Antibiotic decision making in surgical intensive care: a qualitative analysis

BACKGROUND

Antibiotic use in hospitals is high, particularly in surgical specialty and intensive care units. Antimicrobial stewardship programmes (ASPs) are increasingly intervening in antibiotic use by surgeons and intensivists. However, there is limited information on the features which characterize antibiotic decision making in the surgical intensive care unit (SICU), an area in hospital practice where critically ill surgery patients can be kept under close observation.

AIM

To explore the features which characterize antibiotic decision making in the SICU.

METHODS

A total of 160 h of ethnographic observation and 10 semi-structured interviews were conducted at two teaching hospitals in the USA. Data were analysed using thematic coding.

FINDINGS

Three key characteristics of SICU practice with regard to antibiotic use were identified: (1) physical proximity makes SICU clinicians acutely aware of changes in patient status; (2) communication of patient status relies on active involvement by SICU clinicians; (3) SICU clinicians have contested and variable autonomy over antibiotic decisions.

CONCLUSIONS

Antibiotic decision making in the SICU is a complex process involving multiple clinician teams with varying levels of physical proximity to and autonomy over patient cases. This study found that the SICU clinician team has increased physical proximity to patient cases but little autonomy over antibiotic decisions. If these characteristics are not considered, antimicrobial stewardship (AMS) interventions may have diminished success in addressing high levels of the antibiotic use in the SICU.

The learning hospital: From theory to practice in a hospital infection prevention program

The learning hospital is distinguished by ceaseless evolution of erudition, enhancement, and implementation of clinical best practices. We describe a model for the learning hospital within the framework of a hospital infection prevention program and argue that a critical assessment of safety practices is possible without significant grant funding. We reviewed 121 peer-reviewed manuscripts published by the VCU Hospital Infection Prevention Program over 16 years. Publications included quasi-experimental studies, observational studies, surveys, interrupted time series analyses, and editorials. We summarized the articles based on their infection prevention focus, and we provide a brief summary of the findings. We also summarized the involvement of nonfaculty learners in these manuscripts as well as the contributions of grant funding. Despite the absence of significant grant funding, infection prevention programs can critically assess safety strategies under the learning hospital framework by leveraging a diverse collaboration of motivated nonfaculty learners. This model is a valuable adjunct to traditional grant-funded efforts in infection prevention science and is part of a successful horizontal infection control program.

Finding "What's Wrong With Us": Antibiotic Prescribing Practice Among Physicians in the United States

Antibiotic stewardship-or the responsible use of antibiotics-has been touted as a solution to the problem of antibiotic resistance. Antibiotic stewardship in medical institutions attempts to change the antibiotic prescribing "behaviors" and "habits" of physicians. Interventions abound targeting "problem prescribers," or those physicians whose practice is out of line with physician peers. Thus, the locus of decision-making in antibiotic prescribing is thought to be the found with the individual physician. Based on 18 months of participant observation and in-depth interviewing of antibiotic-prescribing physicians at two medical institutions in the United States, this paper will question notions of antibiotic stewardship that center on individual "behaviors" and "habits." Many physicians have taken to heart a reductionist approach in studies of antibiotic prescribing, including several physicians I encountered during research who enthusiastically located the benefit of my research in the ability to identify "what's wrong with us." In this paper, I use two representative ethnographic case studies to argue that antibiotic stewardship interventions aimed at identifying and correcting "bad" physician practice limit the possibilities of understanding the social dynamics of the institution. Through an analysis of everyday encounters in the hospital setting, I show how decision-making in antibiotic prescribing can more productively be located between and among institutions, physicians, patient charts, and other hospital-based staff members (e.g., pharmacists, nurses). By demonstrating that antibiotic prescribing is a collective practice occurring through engagement with social and material surroundings, I argue that we can better account for the weighted ways in which social action and relations unfold over time.

Antimicrobial stewardship programs; a two-part narrative review of step-wise design and issues of controversy Part I: step-wise design of an antimicrobial stewardship program

Regardless of one's opinion of antimicrobial stewardship programs (ASPs), it is hardly possible to work in hospital care and not be exposed to the term or its practical effects. Despite the term being relatively new, the number of publications in the field is vast, including several excellent reviews of general and specific aspects. Work in antimicrobial stewardship is complex, and includes not only aspects of infectious disease and microbiology, but also of epidemiology, genetics, behavioural psychology, systems science, economics and ethics, to name a few. This review aims to take several of these aspects and the scientific evidence of antimicrobial stewardship studies and merge them into two questions: How should we design ASPs based on what we know today? And which are the most essential unanswered questions regarding antimicrobial stewardship on a broader scale? This narrative review is written in two separate parts aiming to provide answers to the two questions. This first part is written as a step-wise approach to designing a stewardship intervention based on the pillars of unmet need, feasibility, scientific evidence and necessary core elements. It is written mainly as a guide to someone new to the field. It is sorted into five distinct steps: (a) focusing on designing aims; (b) assessing performance and local barriers to rational antimicrobial use; (c) deciding on intervention technique; (d) practical, tailored design including core element inclusion; and (e) evaluation and sustainability. The second part, published separately, formulates ten critical questions on controversies in the field of antimicrobial stewardship. It is aimed at clinicians and researchers with stewardship experience and strives to promote discussion, not to provide answers.

Antimicrobial stewardship staffing: How much is enough?

Antimicrobial stewardship improves patient care and reduces antimicrobial resistance, inappropriate use, and adverse outcomes. Despite high-profile mandates for antimicrobial stewardship programs across the healthcare continuum, descriptive data, and recommendations for dedicated resources, including appropriate physician, pharmacist, data analytics, and administrative staffing support, are not robust. This review summarizes the current literature on antimicrobial stewardship staffing and calls for the development of minimum staffing recommendations.

Antimicrobial prescribing and determinants of antimicrobial resistance: a qualitative study among physicians in Pakistan

Background Understanding physicians' perception about antimicrobial use and resistance is essential to ensure that the objectives of the Pakistan national action plan on antimicrobial resistance are met. Little is currently known about physicians' perceptions in Pakistan. Objective Assess physicians' perception surrounding antibiotic use and resistance, factors influencing antibiotic prescribing and potential interventions to improve future antibiotic prescribing. Settings The study was conducted in Lahore, the capital of the province of Punjab, which is the second largest and most populous city of Pakistan. Method Qualitative study was conducted with a semi-structured interview guide involving in-depth face-to-face interviews with purposively selected physicians. Audiorecorded interviews were transcribed verbatim and transcripts analyzed by thematic content analysis. Main outcome measures Themes surrounding the perspectives of physicians on issues of antimicrobial use and resistance. Results Five major themes emerged: (1) knowledge and perception of physicians about antimicrobials, (2) antimicrobial prescribing behaviors of physicians, (3) factors influencing prescribing, (4) determinants of antimicrobial resistance, (5) and potential interventions to reduce antimicrobial resistance. The main challenges and issues associated with antibiotic prescribing were the improvement of knowledge, implementation of hygienic measures, access to and clarity of treatment recommendations and minimizing external factors influencing prescribing including pharmaceutical company activities. Suggestions for the future included stricter regulations for prescribing, improved diagnosis, availability of local guidelines and monitoring of prescribing and resistance patterns. Conclusion Identification of concerns regarding inappropriate antimicrobial prescribing will enable specific initiatives and approaches to improve future antimicrobial use and reduce antimicrobial resistance in Pakistan.

Health Care Providers' Perceptions of Antimicrobial Use and Stewardship at Acute Care Hospitals in Nova Scotia

BACKGROUND

Antimicrobial use is the major factor in the development of antimicrobial resistance. Antimicrobial stewardship has been recommended as a strategy to improve antimicrobial use.

OBJECTIVE

To learn about health care providers' perceptions of current antimicrobial use and stewardship, including barriers and facilitators to improving antimicrobial use at acute care hospitals in Nova Scotia.

METHODS

This qualitative research study was conducted at acute care hospitals in Nova Scotia using focus groups and semistructured interviews. Health care providers (nurses, nurse practitioners, pharmacists, pharmacy students, and physicians) were invited to participate. Focus groups and interviews were conducted at each participant's place of employment. Interviews and focus groups were facilitated with an interview guide, audio-recorded, and transcribed verbatim. Transcripts were independently coded by 2 investigators and analyzed using thematic analysis.

RESULTS

A total of 9 focus groups and 3 individual interviews were conducted between June and August 2017. Fifty-four health care professionals and trainees (24 pharmacists and pharmacy students, 14 physicians, and 16 nurses and nurse practitioners) from 5 hospitals participated. The following themes were identified: current practices, prescribing influences, access to information, collaboration and communication, resources, and antimicrobial stewardship. Within each theme, barriers and facilitators to improving antimicrobial use were identified as subthemes.

CONCLUSION

Participants identified current barriers to appropriate use of antimicrobials and suggested facilitators that might improve the use of these drugs. The results of this study could be used by antimicrobial stewardship teams and decision-makers to improve antimicrobial use and stewardship initiatives throughout Nova Scotia, and may be applicable to hospitals outside the province.

Education and management of antimicrobials amongst nurses in Africa-a situation analysis: an Infection Control Africa Network (ICAN)/BSAC online survey

Objectives

To assess the current involvement of nurses in the use and management of antimicrobials and their training in antimicrobial stewardship (AMS) across Africa.

Methods

After a pilot study, an online questionnaire (SurveyMonkey) in both French and English was circulated via the Infection Control Africa Network (ICAN) mailing list to both members and non-members in Africa. The study was conducted from 26 May to 19 August 2016. Data were summarized in proportions and bar charts; proportions were compared using the χ2 test. A multivariate logistic regression model was built to identify independent factors associated with the practice of AMS.

Results

While 96% of the 173 respondents were aware of the term 'AMS', 88.5% (146/165) undertook AMS tasks as part of their job; 91.9% (158/172) wanted to be more involved in AMS but 44.9% (71/158) reported there were barriers in doing so. AMS training was delivered to 36.7% (62/169) and 53.6% (90/168), respectively, during their undergraduate and postgraduate education. AMS training for healthcare workers in their institutions was reported by 50.3% (86/171), including training aimed at doctors (56.9%), pharmacists (76.7%), microbiologists (31.4%) and nurses (95.3%). However, 95.4% (164/172) of respondents asked for further education on AMS and the majority preferred AMS training to be part of the infection prevention curriculum (IPC) education. Three-quarters of institutions had an AMS initiative, but only ∼41% reported having seen a national AMS guideline.

Conclusions

For Africa, we recommend AMS education at undergraduate level, AMS policies at institution and national levels and incorporating AMS training into the IPC for nurses.

Perspective of Pakistani Physicians towards Hospital Antimicrobial Stewardship Programs: A Multisite Exploratory Qualitative Study

Background: Antimicrobial resistance (AMR) is a global threat and the antimicrobial stewardship program (ASP) is a globally used tool to combat AMR. There is little information on the views among Pakistani physicians regarding AMR and the benefits of hospital antimicrobial stewardship implementation. This study was designed to explore the physicians’ views about ASP. Methods: Qualitative face-to-face and telephonic interviews were conducted by using purposive sampling method with 22 physicians working in seven tertiary care public hospitals of Punjab, Pakistan. All interviews were audio recorded and transcribed verbatim. Qualitative software was used, and a thematic analysis was conducted. Results: Three broad themes were identified: (1) the growing concern of antimicrobial resistance in Pakistan, (2) the role(s) of healthcare professionals in antibiotic prescribing, and (3) managing antibiotic resistance in hospitals. Inadequate resources, poor healthcare facilities, and insufficiently trained medical staff were the major hurdles in ASP implementation in Pakistan. Conclusions: Our study found a poor familiarity of hospital ASP among physicians working in public sector tertiary care teaching hospitals, and a number of distinct themes emerged during this study that could be helpful in establishing the concept of hospital ASP in Pakistan. Overall, physicians showed a positive attitude towards the enforcement of ASP in all healthcare settings, including teaching hospitals.

Pharmacist participation in antimicrobial stewardship in Australian and French hospitals: a cross-sectional nationwide survey

Background

Hospital pharmacists are an integral part of antimicrobial stewardship (AMS) programmes globally. Currently, little is known as to how hospital pharmacists see their role and involvement within the AMS framework.

Objectives

To assess the current level of involvement of Australian and French hospital pharmacists in AMS programmes and identify barriers limiting their involvement in AMS.

Methods

Hospital pharmacists throughout Australia and France were invited to participate in a nationwide online survey throughout March-May 2016. The survey was promoted through the national hospital pharmacists' association in Australia, while a stratified sampling method was used in France to invite pharmacists working in a variety of hospital settings.

Results

Invitations to participate in this survey were sent to 334 Australian pharmacists and 482 French pharmacists. Responses from 133 Australian and 126 French pharmacists were included for analysis. A total of 78.4% (203/259) of pharmacists reported the presence of an AMS programme. Pharmacists were most likely to be involved in AMS through assessing total antibiotic consumption and participating in AMS committee meetings. Barriers to participating in AMS included a lack of time and substantial non-clinical activities limiting involvement in AMS. Differences in responses were found between the two countries.

Conclusions

While the majority of pharmacists reported the presence of an AMS programme, multiple barriers to participation were identified by pharmacists in both countries. Further research should consider how to overcome the identified barriers to optimize the involvement of pharmacists in AMS.
