The impact of a computerised decision support system on antibiotic usage in an English hospital

A systematic review of national interventions and policies to optimize antibiotic use in healthcare settings in England

OBJECTIVES

To identify and assess the effectiveness of national antibiotic optimization interventions in primary and secondary care in England (2013-2022).

METHODS

A systematic scoping review was conducted. Literature databases (Embase and Medline) were used to identify interventions and evaluations. Reports included the UK AMR Strategy (2013-2018), National Action Plan (2019-2024) and English Surveillance Programme for Antimicrobial Utilisation and Resistance (ESPAUR) reports (2014-2022). The design, focus and quality of evaluations and the interventions' effectiveness were extracted.

FINDINGS

Four hundred and seventy-seven peer-reviewed studies and 13 reports were screened. One hundred and three studies were included for review, identifying 109 interventions in eight categories: policy and commissioning (n = 9); classifications (n = 1); guidance and toolkits (n = 22); monitoring and feedback (n = 17); professional engagement and training (n = 19); prescriber tools (n = 12); public awareness (n = 17); workforce and governance (n = 12).Most interventions lack high-quality effectiveness evidence. Evaluations mainly focused on clinical, microbiological or antibiotic use outcomes, or intervention implementation, often assessing how interventions were perceived to affect behaviour. Only 16 interventions had studies that quantified effects on prescribing, of which six reported reductions. The largest reduction was reported with structural-level interventions and attributed to a policy and commissioning intervention (primary care financial incentives). Behavioural interventions (guidance and toolkits) reported the greatest impact in hospitals.

CONCLUSIONS

Many interventions have targeted antibiotic use, each pulling different levers across the health system simultaneously. On the basis of these studies, structural-level interventions may have the greatest impact. Collectively, the combination of interventions may explain England's decline in prescribing but direct evidence of causality is unavailable.

The Impact of Antifungal Stewardship on Clinical and Performance Measures: A Global Systematic Review

BACKGROUND

Antimicrobial stewardship programs (ASP) have been proposed as an opportunity to optimize antifungal use. The antifungal resistance is a significant and emerging threat. The literature on antifungal stewardship (AFS) and its influence on performance and clinical outcome measures is scarce. This study aimed to examine global evidence of the impact of AFS on patients and performance measures.

METHODS

The "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" (PRISMA) was used for the flow of identification, screening, eligibility, and inclusion. PubMed and MEDLINE were searched using the term ''antifungal stewardship'' on 15 February 2023. Search terms included antifungal stewardship, antimicrobial stewardship, candida, candidemia, candiduria, and invasive fungal disease. Of the 1366 records, 1304 were removed since they did not describe an antifungal stewardship intervention. Among the 62 full texts assessed, 21 articles were excluded since they were non-interventional studies and did not include the outcome of interest. Thus, 41 articles were eligible for systematic review. Eligible studies were those that described an AFS program and evaluated clinical or performance measures.

RESULTS

Of the 41 included studies, the primary performance measure collected was antifungal consumption (22 of 41), and mortality (22 of 41), followed by length of stay (11 of 41) and cost (9 of 41). Most studies were single-center, quasi-experimental, with varying interventions across studies. The principal finding from most of the studies in this systematic review is a reduction in mortality expressed in different units and the use of antifungal agents (13 studies out of 22 reporting mortality). Antifungal consumption was significantly blunted or reduced following stewardship initiation (10 of 22). Comparing studies was impossible due to a lack of standard units, making conducting a meta-analysis unfeasible, which would be a limitation of our study.

CONCLUSION

It has been shown that AFS interventions may improve antifungal consumption and other performance measures. According to available published studies, antifungal consumption and mortality appear to be the possible performance measures to evaluate the impact of AFS.

Healthcare Professionals’ Perceptions, Barriers, and Facilitators towards Adopting Computerised Clinical Decision Support Systems in Antimicrobial Stewardship in Jordanian Hospitals

Understanding healthcare professionals’ perceptions towards a computerised decision support system (CDSS) may provide a platform for the determinants of the successful adoption and implementation of CDSS. This cross-sectional study examined healthcare professionals’ perceptions, barriers, and facilitators to adopting a CDSS for antibiotic prescribing in Jordanian hospitals. This study was conducted among healthcare professionals in Jordan’s two tertiary and teaching hospitals over four weeks (June–July 2021). Data were collected in a paper-based format from senior and junior prescribers and non-prescribers (n = 254) who agreed to complete a questionnaire. The majority (n = 184, 72.4%) were aware that electronic prescribing and electronic health record systems could be used specifically to facilitate antibiotic use and prescribing. The essential facilitator made CDSS available in a portable format (n = 224, 88.2%). While insufficient training to use CDSS was the most significant barrier (n = 175, 68.9%). The female providers showed significantly lower awareness (p = 0.006), and the nurses showed significantly higher awareness (p = 0.041) about using electronic prescribing and electronic health record systems. This study examined healthcare professionals’ perceptions of adopting CDSS in antimicrobial stewardship (AMS) and shed light on the perceived barriers and facilitators to adopting CDSS in AMS, reducing antibiotic resistance, and improving patient safety. Furthermore, results would provide a framework for other hospital settings concerned with implementing CDSS in AMS and inform policy decision-makers to react by implementing the CDSS system in Jordan and globally. Future studies should concentrate on establishing policies and guidelines and a framework to examine the adoption of the CDSS for AMS.

Antibiotic Utilization during COVID-19: Are We Over-Prescribing?

The aims of this study were to analyze the utilization of antibiotics before (2018, 2019) and during the COVID-19 pandemic (2020) and the practice of prescribing antibiotics in outpatient settings for COVID-19 patients during the 2020-2022 period. The Anatomical Therapeutic Chemical Classification/Defined Daily Dose methodology was used for the analysis of outpatient antibiotic utilization in the Republic of Srpska. The data was expressed in DDD/1000 inhabitants/day. The rate of antibiotics prescribed to COVID-19 outpatients was analyzed using medical record data from 16,565 patients registered with B34.2, U07.1, and U07.2 World Health Organization International Classification of Diseases 10th revision codes. During 2020, outpatient antibiotic utilization increased by 53.80% compared to 2019. At least one antibiotic was prescribed for 91.04%, 83.05%, and 73.52% of COVID-19 outpatients during 2020, 2021, and the first half of 2022, respectively. On a monthly basis, at least one antibiotic was prescribed for more than 55% of COVID-19 outpatients. The three most commonly prescribed antibiotics were azithromycin, amoxicillin/clavulanic acid, and doxycycline. The trend of repurposing antibiotics for COVID-19 and other diseases treatment might be a double-edged sword. The long-term effect of this practice might be an increase in antimicrobial resistance and a loss of antibiotic effectiveness.

Association Between Antimicrobial Stewardship Programs and Antibiotic Use Globally: A Systematic Review and Meta-Analysis

IMPORTANCE

Antimicrobial resistance continues to spread rapidly at a global scale. Little evidence exists on the association of antimicrobial stewardship programs (ASPs) with the consumption of antibiotics across health care and income settings.

OBJECTIVE

To synthesize current evidence regarding the association between antimicrobial stewardship programs and the consumption of antibiotics globally.

DATA SOURCES

PubMed, Web of Science, and Scopus databases were searched from August 1, 2010, to Aug 1, 2020. Additional studies from the bibliography sections of previous systematic reviews were included.

STUDY SELECTION

Original studies of the association of ASPs with antimicrobial consumption across health care and income settings. Animal and environmental studies were excluded.

DATA EXTRACTION AND SYNTHESIS

Following the Preferred Reporting Items in Systematic Reviews and Meta-Analyses guideline, the pooled association of targeted ASPs with antimicrobial consumption was measured using multilevel random-effects models. The Effective Public Health Practice Project quality assessment tool was used to assess study quality.

MAIN OUTCOMES AND MEASURES

The main outcome measures were proportion of patients receiving an antibiotic prescription and defined daily doses per 100 patient-days.

RESULTS

Overall, 52 studies (with 1 794 889 participants) measured the association between ASPs and antimicrobial consumption and were included, with 40 studies conducted in high-income countries and 12 in low- and middle-income countries (LMICs). ASPs were associated with a 10% (95% CI, 4%-15%) reduction in antibiotic prescriptions and a 28% reduction in antibiotic consumption (rate ratio, 0.72; 95% CI, 0.56-0.92). ASPs were also associated with a 21% (95% CI, 5%-36%) reduction in antibiotic consumption in pediatric hospitals and a 28% reduction in World Health Organization watch groups antibiotics (rate ratio, 0.72; 95% CI, 0.56-0.92).

CONCLUSIONS AND RELEVANCE

In this systematic review and meta-analysis, ASPs appeared to be effective in reducing antibiotic consumption in both hospital and nonhospital settings. Impact assessment of ASPs in resource-limited settings remains scarce; further research is needed on how to best achieve reductions in antibiotic use in LMICs.

Evaluation of Self-Medication with Antibiotics in Primary Care Clinics in Palestine

BACKGROUND

Antibiotics are highly effective medications and essential in curing infectious diseases; however, their inappropriate use, such as self-medication, is a significant factor in developing antimicrobial resistance.

OBJECTIVE

This study aimed to evaluate the level of antibiotic self-medication among patients who visited primary care clinics in Palestine.

METHODS

Data were collected via a self-administered questionnaire, either printed or electronically, using google forms (Google Inc., USA). The sample size needed to provide a 95% confidence level and 5% margin error and assuming a prevalence of 50% of SM with antibiotics was 377 patients. A total of 700 questionnaires were randomly distributed to patients aged 18 years or older. However, 87 were excluded due to duplication, incomplete responses, or participants under 18 years old. Finally, 423 patients were included in this study, with 254 patients completing the electronic Google Forms and 181 completing the written survey. The questionnaire consists of patients' demographics, antibiotics knowledge, and self-medication behavior. In addition, descriptive statistics and knowledge scales were performed using SPSS 22 IBM to measure and assess the scope of the problem and find the association between self-medication demographics, education, and socioeconomic status.

RESULTS

Approximately 50% of participants reported self-medication with antibiotics, with a very high use among participants with medical knowledge. Most people have adequate awareness of antibiotics, whereas out of 423 respondents, (40.2%, n = 170) had GKL, (50.4%, n= 213) had AKL, and only (9.5%, n=40) presented PKL. The primary source for self-treatment with antibiotics was community pharmacies (87.1%, n=223), whereas (14.1%, n=36) got antibiotics from family and friends. Convenience, easy access, and experience with community pharmacists contributed to self-medications. The most commonly used antibiotic for self-medication was amoxicillin/clavulanic acid.

CONCLUSION

Self-medication with antibiotics is a common practice in Palestine, regardless of socioeconomic or educational status. Patients' educations about complications from inappropriate use and the possibility of side effects are essential steps to decrease patients' demands for antibiotics. Furthermore, compliance and adherence of community pharmacists in dispensing antibiotics only with a prescription is necessary.
