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

Can Antibiotic Stewardship Be Achieved by Utilizing the Stewardship Through Educating Patients (S.T.E.P.) Process?

BACKGROUND

Despite research and efforts to mitigate bacterial resistance, antibiotic overprescribing continues to occur, often due to real or perceived expectations of patients.  Objective: The purpose of this study was to determine: (1) if there's an association between the provider's patient education efforts and the patient's satisfaction, and (2) the research participant's subsequent behavior concerning antibiotic prescriptions, by utilizing the Stewardship Through Educating Patients (S.T.E.P.) process for positive prescriptive change. The S.T.E.P. program features straightforward, simple education via face-to-face counseling at patient encounters, along with presenting applicable printed educational pamphlets from the Centers for Disease Control and Prevention (CDC). These two interventions were utilized in this study with research participants from the healthcare provider, with education focused on appropriate antibiotic use in the treatment of adults diagnosed with common illnesses such as an upper respiratory infection (the common cold), acute sinusitis, and acute bronchitis, which oftentimes are viral in origin.

METHOD

This Quality Improvement (QI) interventional study utilized the researcher's direct face-to-face patient education and CDC printed materials as a measure of antibiotic prescribing as a primary outcome, with patient satisfaction as a secondary outcome via convenience sampling of 40 hospital employees who utilized a free hospital-based employee healthcare clinic.

RESULTS

Patient-teaching by this study's researcher, along with supplemental printed patient education material from the CDC that were given to research participants during an initial medical encounter, were effective interventions used in reducing antibiotic prescribing, as evidenced by a positive patient satisfaction in 95% of research participants.

CONCLUSIONS

Antibiotic use in the treatment of adults diagnosed with common illnesses such as an upper respiratory infection (the common cold), acute sinusitis, and acute bronchitis, may be safely reduced by using a combination of patient-education and clinician intervention.

Short and Concise Peer-to-Peer Teaching—Example of a Successful Antibiotic Stewardship Intervention to Increase Iv to Po Conversion

Antibiotic stewardship (ABS) programs aim to combine effective treatment with minimized antibiotic-related harms. Common ABS interventions are simple and effective, but their implementation in daily practice is often difficult. The aim of our study was to investigate if a single, short, peer-to-peer teaching intervention (junior doctor to junior doctor) during clinical routine can successfully improve antibiotic prescriptions. We performed a quasi-experimental before–after study on a regular care cardiology ward at a large academic medical center in Germany. We evaluated antibiotic use metrics retrospectively and calculated defined daily doses (DDD) with the anatomical therapeutic chemical/DDD classification system of the World Health Organization. We hypothesize that the over-representative use of intravenous administration is a potentially modifiable target, which can be proven by antibiotic use metrics analysis. After a single peer-to-peer teaching session with a focus on indications for iv to po conversion, the normalized percentage of intravenous compared to oral administration significantly decreased (from 86.5 ± 50.3% to 41.4 ± 70.3%). Moreover, after the intervention, antibiotics with high oral bioavailability were no longer administered intravenously at all during the following quarter. Our results indicate that even a single peer-to-peer training session is highly effective in improving the iv to po conversion rate in the short term.

A commitment and call to strengthen and expand qualitative research efforts to improve the impact of antimicrobial stewardship

Inadequate recognition of the value of qualitative research in healthcare, notably in antimicrobial stewardship (AMS), in addition to a lack of publishing space in medical journals has prompted JAC-Antimicrobial Resistance to focus on a qualitative series of AMS papers to incite interest in and support for pivotal qualitative approaches that make an indispensable contribution to our understanding of antibiotic use and how to address antimicrobial resistance. In this series, invited authors with diverse backgrounds and considerable expertise address and review intricate and varying qualitative research methods, behaviour change determinants, interventions and qualitative perspectives, with the aim of strengthening commitment and expanding qualitative initiatives to further the impact of AMS globally.

Assessing feasibility of establishing antimicrobial stewardship programmes in two provincial-level hospitals in Vietnam: an implementation research study

OBJECTIVES

To investigate the feasibility of establishing hospital-based antimicrobial stewardship (AMS) programmes comprising action-planning, educational interventions and data feedback in two provincial-level hospitals in Viet Nam.

DESIGN AND SETTING

This was an implementation research using participatory action process and existing resources from the Duke Antimicrobial Stewardship Outreach Network with local adjustments. A national stakeholder meeting and Strengths-Weaknesses-Opportunities-Threats (SWOT) analysis were conducted to identify gaps and potential interventions.

PARTICIPANTS

Hospital AMS staff implemented activities throughout the study phases. Routinely collected patient data were analysed to support planning, implementation and evaluation.

INTERVENTIONS

Hospitals were considered as a complex adaptive system and leveraged their unique characteristics and interconnections to develop 1-year plans containing core interventions (data use, educational training, prospective audit with feedback (PAF) and evaluations).

OUTCOME MEASURES

We assessed feasibility using outputs from stakeholder meeting, SWOT analysis, baseline data, planning process and implementation.

RESULTS

The stakeholder meeting identified three gaps for AMS at national level: supportive policies, AMS training and core competencies and collaboration. At the hospitals, AMS programmes took 1 year for planning due to lack of hospital-specific procedures and relevant staff competencies. Baseline data (January-December 2019) showed variations in antibiotic consumption: 951 days of therapy (DOT) per 1000 days present in the control and 496 in the intervention wards in hospital 1, and 737 and 714 in hospital 2, respectively. During 1-year implementation, clinical pharmacists audited 1890 antibiotic prescriptions in hospital 1 (June 2020-May 2021) and 1628 in hospital 2 (July 2020-July 2021), and will continue PAF in their daily work.

CONCLUSION

Our data confirmed the need to contextualise AMS programmes in low-income and middle-income countries (LMICs) and demonstrated the usefulness of implementation research design in assessing programme feasibility. Developing staff competencies, using local data to stimulate actions and integrating programme activities in routine hospital work are key to success in LMICs.

Are We Making the Most of Community Pharmacies? Implementation of Antimicrobial Stewardship Measures in Community Pharmacies: A Narrative Review

Community pharmacists recognize the need to implement antimicrobial stewardship activities in community pharmacies. They are in a unique position to provide triage for common primary care indications and to lower the burden of patients at general practitioners’ offices. However, research shows that, in some areas, dispensing of antimicrobials without valid prescription is still highly prevalent. Regardless of training, every community pharmacist can give his contribution to antimicrobial stewardship. One of the basic elements should be antimicrobial dispensing according to regulations, either prescription only, or according to guidelines where pharmacists have prescribing authority. Patient consultation supported with educational materials, such as leaflets, may reduce patients’ expectations to receive antibiotics for self-limiting infections and reduce pressure on general practitioners to prescribe antibiotics on patients’ demand. Treatment optimization may be achieved in collaboration with the prescribing general practitioners or by providing feedback. At last, pharmacists provided with additional training may be encouraged to provide consultation services to long-term care facilities, to introduce point-of-care testing for infectious diseases in their pharmacies or prescribe antimicrobials for uncomplicated infections. These services are welcomed by patients and communities. Expanding pharmacy services and pharmacists’ prescribing autonomy have shown a positive impact by reducing antibiotics consumption, thus ensuring better compliance with treatment guidelines.

Antimicrobial Stewardship: Fighting Antimicrobial Resistance and Protecting Global Public Health

Antimicrobial resistance (AMR) is a serious threat to global public health. It increases morbidity and mortality, and is associated with high economic costs due to its health care burden. Infections with multidrug-resistant (MDR) bacteria also have substantial implications on clinical and economic outcomes. Moreover, increased indiscriminate use of antibiotics during the COVID-19 pandemic will heighten bacterial resistance and ultimately lead to more deaths. This review highlights AMR's scale and consequences, the importance, and implications of an antimicrobial stewardship program (ASP) to fight resistance and protect global health. Antimicrobial stewardship (AMS), an organizational or system-wide health-care strategy, is designed to promote, improve, monitor, and evaluate the rational use of antimicrobials to preserve their future effectiveness, along with the promotion and protection of public health. ASP has been very successful in promoting antimicrobials' appropriate use by implementing evidence-based interventions. The "One Health" approach, a holistic and multisectoral approach, is also needed to address AMR's rising threat. AMS practices, principles, and interventions are critical steps towards containing and mitigating AMR. Evidence-based policies must guide the "One Health" approach, vaccination protocols, health professionals' education, and the public's awareness about AMR.
