Systematic review of factors promoting behaviour change towards antibiotic use in hospitals

Duration of antibiotic therapy in the intensive care unit: factors influencing decision-making during multidisciplinary meetings

OBJECTIVES

In the intensive care unit (ICU), antibiotics are often given longer than recommended in guidelines. A better understanding of the factors influencing antibiotic therapy duration is needed to develop improvement strategies to effectively address these drivers of excessive duration. This study aimed to explore the determinants of adherence to recommended antibiotic therapy durations among healthcare professionals involved in antibiotic decision-making within the ICU, focusing on multidisciplinary meetings (MDMs).

METHODS

Semistructured interviews were held with healthcare professionals involved in antibiotic decision-making during MDMs in four Dutch ICUs. Participants included intensivists, clinical microbiologists and ICU residents. Transcripts were analysed using deductive and inductive content analysis methods.

RESULTS

A total of 20 participants were interviewed. The interviews revealed that decision-making regarding antibiotic therapy duration is a complex process, primarily centred around professional interactions during MDMs and involving a broad range of determinants. These determinants were categorised into the following four steps: (1) the introduction of duration as a topic for discussion in the MDM (eg, lack of priority to discuss antibiotic therapy duration); (2) the discussion of antibiotic therapy duration itself (eg, lack of core members during MDM); (3) the establishment of a concrete decision (eg, lack of documentation of the decisions made); (4) the execution of the decision (eg, forgetting to stop antibiotics).

CONCLUSIONS

Our study identified numerous factors that influence decisions about the duration of antibiotic therapy during MDMs in the ICU. By describing these factors throughout the decision-making process, we provided valuable insights into barriers that commonly arise in specific steps, highlighting critical areas for improvement. Daily MDMs were deemed essential for informed decision-making regarding antibiotic therapy duration by the interviewees. Strategies to improve appropriate duration in the ICU should prioritise strengthening interdisciplinary communication between healthcare professionals and adding structure to these meetings.

The imperative of teamwork in antimicrobial stewardship (AMS) interventions: insights from an ethnographic study with practitioners in Spain

Teamwork-the activity of working together in a group towards a similar goal-is a defining feature of the practice of clinical medicine carried out in hospitals and other healthcare facilities. This Viewpoint suggests that teamwork is a defining feature of antimicrobial stewardship (AMS) programmes, and identifies six elements that characterise AMS team dynamics. These insights arise from an original ethnographic study of AMS carried out in Spain, where these programmes are known as Programas para la Optimización de Antimicrobianos. The study used qualitative research methods including ethnographic observations in public hospitals and scientific and educational fora, in-depth interviews and archival research. It calls for a reflection on the part of the global community of AMS practitioners on the role of team dynamics in building sustainable AMS interventions and the inclusion of teamwork skills in training curricula aimed at future practitioners.

The Impact of National Activities on Antibiotic Consumption in Hospitals and Different Departments over a 14-Year Period

The aim of this study was to assess the use of antibiotics in hospitals and different departments over 14 years (2006-2019) and the impact of various national activities related to this, including national audits of the use of antibiotics for systemic use. The consumption of antibiotics for systemic use (J01) from all Slovenian hospitals (n = 29) and five departments (internal medicine, surgery, ICU (medicine, surgery), paediatrics and gynaecology/obstetrics) was collected. Total hospital consumption was expressed as the number of defined daily doses (DDDs) per 1000 inhabitants per day (DID), the number of DDDs/100 bed days and the number of DDDs/100 admissions. Over 14 years, J01 hospital consumption increased by 13.8%, expressed in DDDs/100 bed days (p = 0.002). In 2019, compared to 2006, the consumption of J01, expressed in DDD/100 bed days, increased from 19.9% to 33.1% in all departments, except intensive care units. J01 consumption expressed in DDD/100 admissions increased by 7.0% to 39.4% in all but paediatric wards (where it decreased by 12.7%). In all years, we observed large variations in the consumption of antibiotics in departments of the same type. The effectiveness of audit interventions aimed at optimizing antibiotic consumption exhibited notable variation across hospitals, with specialized facilities generally demonstrating superior outcomes compared to general hospitals.

Evaluation of Hospital Antimicrobial Stewardship Programs: Implementation, Process, Impact, and Outcomes, Review of Systematic Reviews

Antimicrobial Stewardship Programs (ASP) were introduced in healthcare as a public health priority to promote appropriate prescribing of antimicrobials, to reduce adverse events related to antimicrobials, as well as to control the escalating challenges of antimicrobial resistance. To deliver aimed outcome objectives, ASPs involve multiple connected implementation process measures. A systematic review was conducted to evaluate both concepts of ASPs. Guided by PRISMA frames, published systematic reviews (SR) focusing on ASPs restricted to secondary and tertiary healthcare were evaluated over the past 10 years involving all age groups. Out of 265 identified SR studies, 63 met the inclusion criteria. The majority were conducted in Europe and North America, with limited studies from other regions. In the reviewed studies, all age groups were examined, although they were conducted mainly on adults when compared to children and infants. Both process and outcomes measures of ASPs were examined equally and simultaneously through 25 different concepts, dominated by efficacy, antimicrobial resistance, and economic impact, while information technology as well as role of pharmacy and behavioral factors were equally examined. The main broad conclusions from the review were that, across the globe, ASPs demonstrated effectiveness, proved efficacy, and confirmed efficiency, while focused evaluation advocated that developed countries should target medium- and small-sized hospitals while developing countries should continue rolling ASPs across healthcare facilities. Additionally, the future of ASPs should focus on embracing evolving information technology to bridge the gaps in knowledge, skills, and attitude, as well as to enhance appropriate decision making.

Evaluation of prescription review and feedback policy on rational antibiotic use in primary healthcare settings in Beijing, China: a qualitative study using the Theoretical Domains Framework and the behaviour change wheel

Objectives

To decelerate antibiotic resistance driven by inappropriate antibiotic prescribing, a prescription review and feedback (PRF) policy is implemented in primary healthcare institutions (PHIs) in Beijing, China. However, evaluation of PRF implementation in PHIs is scarce. This study aims to systematically identify the barriers and facilitators of PRF policy implementation to provide evidence for antimicrobial stewardship.

Methods

We conducted key informant interviews with 40 stakeholders engaged in the implementation of PRF in Beijing, including physicians, pharmacists and administrators. Interviews were audio recorded and transcribed verbatim. We coded the interview transcripts and mapped informant views to domains of the Theoretical Domains Framework. We then used a behaviour change wheel to suggest possible behavioural interventions.

Results

Procedural knowledge (Knowledge) and skills (Skill) of PRF were possessed by stakeholders. They felt responsible to promote the appropriate use of antibiotics (Social/professional role and identity) and believed that PRF could help to change inappropriate provider behaviours (Behavioural regulation) in prescribing antibiotics (Beliefs about consequences) under increased intention on antibiotic use (Stages of change). Moreover, informants called for a more unified review standard to enhance PRF implementation (Goals). Frequently identified barriers to PRF included inadequate capacity (Skill), using punishment mechanism (Behaviour regulation), reaching consistently lower antibiotic prescription rates (Goals), lack of resources (Environmental context and resources) and perceived pressure coming from patients (Social influences).

Conclusions

Stakeholders believed that PRF implementation promoted the rational use of antibiotics at PHIs in Beijing. Still, PRF was hampered by inconsistencies in review process and resources needed for PRF implementation.

Choosing Wisely internationally - helpful recommendations for antimicrobial stewardship!

PURPOSE

Antimicrobial resistance poses a major threat to human health globally and antibiotic overuse is a main driver of resistance. Antimicrobial stewardship (AMS) was developed to improve the rationale use of antibiotics. The Choosing Wisely campaign was initiated to ameliorate medical practice through avoidance of unnecessary diagnostic and therapeutic procedures. Our objective was to give an overview on the Choosing Wisely recommendations related to AMS practices from a selection of different countries in order to define future needs.

METHODS

We evaluated the seven countries already analyzed for Choosing Wisely recommendations related to topics of infectious medicine before. Finally, we included five of the former countries (Australia/New Zealand, Canada, Italy, Switzerland, and USA) and Germany with easily accessible recommendations and selected those related to six categories of AMS as following: diagnostics, indication, choice of antiinfective drugs, dosing, application and duration of therapy.

RESULTS

In total, 213 recommendations could be extracted related to AMS for the six countries and were matched to the chosen categories. Interestingly, no recommendations were found for the category "dosing." Topics related to indication and diagnostics were most frequently found with 85 and 78 recommendations, respectively. Perioperative prophylaxis was a frequently addressed issue - both related to application, indication and duration. Avoiding antibiotic treatment of asymptomatic bacteriuria and upper respiratory tract infections were central topics of all countries.

CONCLUSION

AMS is an important strategy to fight increasing resistance and is frequently addressed by Choosing Wisely recommendations of different countries. Similar issues are considered important in the selected countries.

Implementation of an antimicrobial stewardship programme in three regional hospitals in the south-east of Liberia: lessons learned

Background

Antimicrobial stewardship (AMS) programmes can improve the use of antimicrobial agents. However, there is limited experience in the implementation of such programmes in low- and middle-income countries (LMICs).

Objectives

To assess the effect of AMS measures in south-east Liberia on the quality of antimicrobial use in three regional hospitals.

Methods

A bundle of three measures (local treatment guideline, training and regular AMS ward rounds) was implemented and quality indicators of antimicrobial use (i.e. correct compounds, dosage and duration) were assessed in a case series before and after AMS ward rounds. Primary endpoints were (i) adherence to the local treatment guideline; (ii) completeness of the microbiological diagnostics (according to the treatment guideline); and (iii) clinical outcome. The secondary endpoint was reduction in ceftriaxone use.

Results

The majority of patients had skin and soft tissue infections (n = 108) followed by surgical site infections (n = 72), pneumonia (n = 64), urinary tract infection (n = 48) and meningitis (n = 18). After the AMS ward rounds, adherence to the local guideline improved for the selection of antimicrobial agents (from 34.5% to 61.0%, P < 0.0005), dosage (from 15.2% to 36.5%, P < 0.0005) and duration (from 13.2% to 31.0%, P < 0.0005). In total, 79.7% of patients (247/310) had samples sent for microbiological analysis. Overall, 92.3% of patients improved on Day 3 (286/310). The proportion of patients receiving ceftriaxone was significantly reduced after the AMS ward rounds from 51.3% to 14.2% (P < 0.0005).

Conclusions

AMS measures can improve the quality of antimicrobial use in LMICs. However, long-term engagement is necessary to make AMS programmes in LMICs sustainable.
