Reduction in antimicrobial use associated with a multifaceted antimicrobial stewardship programme in a tertiary teaching hospital in Shanghai: a segmented regression analysis

Effects of pay-for-performance based antimicrobial stewardship on antimicrobial consumption and expenditure: An interrupted time series analysis

Objectives

To evaluate the impact of pay-for-performance on antimicrobial consumption and antimicrobial expenditure in a large teaching hospital in Guangzhou, China.

Methods

We collected data from hospital information system from January 2018 through September 2022 in the inpatient wards. Antimicrobial consumption was evaluated using antibiotic use density (AUD) and antibiotic use rate (AUR). The economic impact of intervention was assessed by antimicrobial expenditure percentage. The data was analyzed using interrupted time series (ITS) analysis.

Results

Following the implementation of the intervention, immediate decreases in the level of AUD were observed in Department of Hematology Unit 3 (β = -66.93 DDDs/100PD, P = 0.002), Urology (β = -32.80 DDDs/100PD, P < 0.001), Gastrointestinal Surgery Unit 3 (β = -11.44 DDDs/100PD, P = 0.03), Cardiac Surgery (β = -14.30 DDDs/100PD, P = 0.01), ICU, Unit 2 (β = -81.91 DDDs/100PD, P = 0.02) and Cardiothoracic Surgery ICU (β = -41.52 DDDs/100PD, P = 0.05). Long-term downward trends in AUD were also identified in Organ Transplant Unit (β = -1.64 DDDs/100PD, P = 0.02). However, only Urology (β = -6.56 DDDs/100PD, P = 0.02) and Gastrointestinal Surgery Unit 3 (β = -8.50 %, P = 0.01) showed an immediate decrease in AUR, and long-term downward trends in AUR were observed in Pediatric ICU (β = -1.88 %, P = 0.05) and ICU Unit 1 (β = -0.55 %, P = 0.02).

Conclusion

This study demonstrates that the adoption of pay-for-performance effectively reduces antibiotic consumption in specific departments of a hospital in Guangzhou in the short term. However, it is important to recognize that the long-term impact of such interventions is often limited. Additionally, it should be noted that the overall effectiveness of the intervention across the entire hospital was not significant.

Antimicrobial Stewardship Teams in Veterans Affairs and Nonfederal Hospitals in the United States: A National Survey of Antimicrobial Stewardship Practices

In a cross-sectional survey of US acute care hospitals, antimicrobial stewardship programs were present in most Veterans Affairs and nonfederal hospitals but varied in team composition, scope, and impact. Diagnostic stewardship was common across hospitals. Veterans Affairs hospitals had increased reach in outpatient settings. Telestewardship remains an opportunity in all hospital systems.

Role of Pharmacists in Antimicrobial Stewardship During COVID-19 Outbreak: A Scoping Review

Since the beginning of the coronavirus disease 2019 (COVID-19) pandemic, pharmacists have been on the front lines of health care, offering vital services. Consequently, the need for pharmacists to support an effective antibiotic stewardship (AMS) program during the COVID-19 outbreak has become increasingly evident. This scoping review was performed to examine related articles in 2020-2022 published in the Scopus, SAGE, and Cochrane databases with the keywords "Pharmacist" and "Antibiotic Stewardship" and "COVID-19". The inclusion criteria were full-text articles written in English. A total of 15 articles were included in this review to describe the role of pharmacists in AMS during the COVID-19 outbreak. In general, pharmacists are responsible for identifying and treating patients during pandemics, ensuring the continued supply and accessibility of medications, promoting health policies, and monitoring antibiotic use for COVID-19 cases and co-infections. At the hospital, as the most significant element for pharmacists on the AMS team, the apparent change is demonstrated in educating patients on telehealth services, clarifying misconceptions about treatments and antibiotic consumption, as well as taking a leadership position to establish local guidelines for the COVID-19 treatment protocol. Pharmacists have an important role in the AMS program, and the COVID-19 pandemic was perceived as a highlight their importance. Therefore, their work with the AMS program needs to be improved as they learn to extend their role in telehealth services, educate and clarify the misconceptions about COVID-19 treatments and other antibiotic consumption in the community, inventory control the COVID-19 drug, antibiotics, and vaccine, as well as take the lead in establishing local guidelines on antibiotic consumption during the pandemic outbreak.

Effect of the COVID-19 pandemic on antibiotic consumption: A systematic review comparing 2019 and 2020 data

Background

The coronavirus disease 2019 (COVID-19) pandemic has influenced antibiotic consumption over a long period, with variability in trends among studies. We conducted this systematic review to explore and compare the effect of the pandemic on overall and individual antibiotic consumption in 2020 with that in 2019.

Methods

This systematic literature review was conducted using PubMed, EMBASE, and Web of Science databases. Data on antibiotic consumption in Japan was sourced from the Japan Surveillance of Antimicrobial Consumption.

Results

A total of 1,442 articles and reports were screened, and 16 eligible articles were reviewed. The included studies were conducted in Jordan, Australia, Canada, UK, Japan, Brazil, India, China, and the EU. There was no study from African and Southeast Asian Countries. Overall, antibiotic consumption in the community consistently reduced in 2020. Studies from Australia, Canada, Portugal, Spain, the UK, Japan, and the European Union reported both decreases in overall and selected individual antibiotics consumption. In contrast, hospital-based studies reported both increases and decreases. Hospital-based studies in Lebanon, Spain, Italy, India, and the UK reported an increase in antibiotic consumption in 2020. Studies reporting an interruption of antibiotic stewardship programs during the pandemic also reported increases in antibiotic consumption for hospitalized patients in 2020 compared with that in 2019.

Conclusion

Our results showed a different trend between communities and hospitals in antibiotic consumption during 2020 compared to 2019. The continuity of the antibiotic stewardship program might have influenced the antibiotic consumption trend variability among hospitals in 2020. Alongside this, the lack of information on antibiotic consumption from low-income countries and limited reports from middle-income countries revealed gaps that need to be urgently filled.

Antimicrobial Stewardship in Surgery: A Literature Bibliometric Analysis

Background

Antimicrobial resistance and the dwindling antibiotic development pipeline have resulted in a looming post-antibiotic era. Research related to antimicrobial stewardship (AMS) has grown rapidly in the past decade, especially in the field of surgery. We conducted a bibliometric analysis of these publications. In addition, we aimed to identify research hotspots and infer future research trends.

Methods

We screened global publications on AMS in the surgical field over ten years (between 2011 and 2020) from the Web of Science core collection database. The keywords “antimicrobial or antibiotic”, “stewardship”, “management”, “management strategies”, “programme”, “surgery” and “surgical” were used to search for related papers. VOS viewer, R software, and other machine learning and visualization tools were used to conduct the bibliometric analysis of the publications.

Results

We identified 674 publications on AMS in surgical fields; “antimicrobial stewardship” (with total link strength of 1,096) was the most frequent keyword, and had strong links to “antimicrobial resistance” and “guidelines”. The top 100 most cited papers had a mean citation count of 47.21 (range: 17–1155) citations, which were cited by survey research studies, clinical trials, and observational studies. The highest-ranking and most cited journal was Clinical Infectious Diseases with eight publications. Jason G. Newland from Washington University wrote seven papers and was cited 1,282 times. The University of Washington published 17 papers and was cited 1,258 times, with the largest number of publications by author and organization. The USA published 198 papers and cooperated with 21 countries, mainly partnering with Italy, the UK, and Canada. Published articles mainly focused on the current clinical situation regarding surgical AMS management, antibiotic prescription, and antibiotic resistance.

Conclusions

Publications on surgical AMS management have increased in recent decades, with the USA being the most prolific. Epidemiological investigations of surgical-related infections, antibiotic prescriptions, and antibiotic resistance are fast-developing research trends. However, further improvements are still needed according to the recommendations gained from the bibliometric analysis.
