State of the globe: antimicrobial stewardship guides rationale use of antimicrobials to enable faster cure and prevent drug resistance

Trends in the hospital-sector consumption of the WHO AWaRe Reserve group antibiotics in EU/EEA countries and the United Kingdom, 2010 to 2018

BackgroundIn 2019, the World Health Organization published the 21st Model list of Essential Medicines and updated the Access, Watch Reserve (AWaRe) antibiotics classification to improve metrics and indicators for antibiotic stewardship activities. Reserve antibiotics are regarded as last-resort treatment options.AimWe investigated hospital-sector consumption quantities and trends of Reserve group antibiotics in European Union/European Economic Area countries and the United Kingdom (EU/EEA/UK).MethodsHospital-sector antimicrobial consumption data for 2010-2018 were obtained from the European Centre for Disease Prevention and Control. Antibacterials' consumption for systemic use (Anatomical Therapeutic Chemical classification (ATC) group J01) were included in the analysis and expressed as defined daily doses (DDD) per 1,000 inhabitants per day. We defined reserve antibiotics as per AWaRe classification and applied linear regression to analyse trends in consumption of reserve antibiotics throughout the study period.ResultsEU/EEA/UK average hospital-sector reserve-antibiotic consumption increased from 0.017 to 0.050 DDD per 1,000 inhabitants per day over the study period (p = 0.002). This significant increase concerned 15 countries. In 2018, four antibiotics (tigecycline, colistin, linezolid and daptomycin) constituted 91% of the consumption. Both absolute and relative (% of total hospital sector) consumption of reserve antibiotics varied considerably (up to 42-fold) between countries (from 0.004 to 0.155 DDD per 1,000 inhabitants per day and from 0.2% to 9.3%, respectively).ConclusionAn increasing trend in reserve antibiotic consumption was found in Europe. The substantial variation between countries may reflect the burden of infection with multidrug-resistant bacteria. Our results could guide national actions or optimisation of reserve antibiotic use.

Consumption of Antibacterials for Systemic Use in Slovakia: A National Study and the Quality Indicators for Outpatient Antibiotic Use

This paper aims to analyse the consumption of antibiotics in the Slovak health care system from 2011 to 2020. The data source on the consumption of antibiotics is sales data from SUKL and NCZI. The study employed the ATC/DDD Index and focused on the consumption of antibiotics in the primary care sector. Total antibiotic consumption decreased from 19.21 DID in 2011 to 13.16 DID in 2020. Consumption of beta-lactamase-sensitive penicillins, expressed as a percentage of the total consumption of antibiotics, decreased from 8.4% in 2011 to 4.2% in 2020. Consumption of the combination of penicillins, including beta-lactamase inhibitor, expressed as a percentage of the total consumption of antibiotics, increased from 16.2% in 2011 to 17.9% in 2020. Consumption of third- and fourth-generation cephalosporins, expressed as the percentage of the total consumption of antibiotics, increased from 2.0% in 2011 to 4.6% in 2020. Consumption of fluoroquinolones, expressed as the percentage of the total consumption of antibiotics, decreased from 10.7% in 2011 to 8.6% in 2020. Overall, antibiotic consumption significantly changed in Slovakia from 2011 to 2020. The ratio of the consumption of broad-spectrum to the consumption of narrow-spectrum penicillins, cephalosporins and macrolides decreased from 14.98 in 2011 to 13.38 in 2020.

Antibiotic stewardship in a tertiary care hospital of a developing country: establishment of a system and its application in a unit-GASP Initiative

PURPOSE

Despite the proven benefits of antimicrobial stewardship, models for executing the same in the developing countries are sparse. The present study highlights the approaches undertaken by our group in initiating one such program in a public sector tertiary level health care setting of a developing country.

METHODS

The study focussed on development of a system after evaluation of existing issues and case study of implementation of the program in a unit within the hospital. The system building exercise included (1) development of generic data capture form for prospective audit and feedback; (2) development of an electronic system for data capture; (3) identification of key intervention points for strategy decision for stewardship in a particular unit; (4) application of the stewardship method and (5) evaluation of outcomes.

RESULTS

A digital system for prospective audit was constructed after a background study. In the study unit, there was a significant decline in double anaerobic coverage. There was a significant decline in the average number of antimicrobials used per patients and a decrease in Defined Daily Dose of designated antimicrobials was noted. Additionally, there was an increase in the use of optimized doses.

CONCLUSION

A system for undertaking antimicrobial stewardship with a mechanism for prospective audit was put in place. The system may be adopted by other public sector hospitals of the developing country.
