Special Issue Information

Dear Colleagues,

Primary care is responsible for the majority of antibiotic prescribing worldwide, and a substantial amount of antibiotics are used irrationally. Irrational use of antibiotics can take many forms, including the use of unnecessary antibiotics (no indication); the use of too many medicines per patient (polypharmacy); the use of non-recommended fixed-dose combinations including an antibiotic; self-medication with antibiotics without a proper clinical diagnosis (often with prescription-only medicines),; non-adherence to clinical guidelines or use in non-bacterial infections; use in inadequate dosages or with inappropriate routes of administration, such as the overuse of injections when oral formulations would be more appropriate; or treatment withdrawal before ending the recommended course (underuse).All these factors expose bacteria to sub-optimal levels of antibiotics, which are not only therapeutically ineffective but also facilitate the formation of bacterial resistance to the drug.

Irrational antibiotic use in primary care is associated with many factors. Public knowledge, attitudes, and beliefs about antibiotics are strong determinants of irrational antibiotic use. Access to antibiotics without a prescription is also a driving factor for misuse due to a potential lack of access to proper diagnosis and diagnostic tools. Moreover, leftover (remaining) antibiotics from earlier prescriptions, where the patient did not adhere to the therapy or the quantity of prescribed antibiotics exceeded the treatment duration, facilitate the practice of self-medication.

Although there is a rising number of scientific publications regarding irrational antibiotic use in primary care, the following concerns still need to be addressed: the establishment of national pharmacoepidemiology to investigate antimicrobial consumption and draw plans for how to minimize it; pharmaceutical industry involvement in the fight against irrational antibiotic use by monitoring and restricting the sale of antibiotics to community pharmacies; research on the misuse of antibiotics in veterinary practices and the environment/ ecosystem under the “one health” approach; the development of policies and regulations to limit irrational antimicrobial use in low- and middle-income countries; and the implementation of easy access and OTC dispensing of antibiotics. This Special Issue addresses these issues in line with antibiotic management in various settings.

Background: The challenge of emerging antimicrobial resistance and variation in antibiotic use across provinces in China call for knowledge on antibiotic utilization at the regional level. This study aims to evaluate the long-term trends and patterns of antibiotic usage in Xinjiang Province, the largest provincial-level division located in the northwest of China, aiming to provide evidence in enhancing provincial antimicrobial stewardship (AMS) and developing policy measures to optimize regional antimicrobial use. Methods: This was an ecological study with temporal trend analysis on inpatient antibiotic utilization, with antibiotic use data from 92 public hospitals covered by Xinjiang’s Center for Antibacterial Surveillance from 2012 to 2022. Antibiotic use was measured by the number of daily defined doses per 100 patient days (DDDs/100 pds). Patterns of antibiotic use were described by Anatomical Therapeutic Chemical (ATC) subgroups and the Access, Watch, Reserve (AWaRe) classification. The Average Annual Percent Change (AAPC) of antibiotic use and the corresponding 95% confidence intervals (CIs) were calculated to describe the trend of antibiotic use over time. Joinpoint regression was performed using the Weighted Bayesian Information Criteria (WBIC) model with a parametric method. A pairwise comparison between secondary and tertiary hospitals was conducted to explore disparities in antibiotic use across hospital levels. The most commonly used antibiotics were also analyzed. Results: The total inpatient antibiotic use in Xinjiang was 27.6 DDDs/100 patient days in 2022, with a significant decreasing trend during 2012–2022 (AAPC, −2.0%; 95% CI, −3.6% to −0.4%). The Watch group antibiotics were the most used AWaRe category, with the Access-to-Watch ratio decreasing significantly from 46.4% to 24.4% (AAPC, −6.8%; 95% CI, −8.4% to −5.1%). No significant difference was found in the trend of total antibiotic use between secondary and tertiary hospitals, but there were disparities across hospital levels in subgroups. Third-generation cephalosporins, second-generation cephalosporins, and fluoroquinolones remained the top three antibiotic class throughout the study period. The number of antibiotics accounting for 90% of the total antibiotic use decreased from 34 antibiotics in 2012 to 18 antibiotics in 2022. Conclusions: The decreasing trend of inpatient antibiotic use in Xinjiang’s public hospitals reflects the effects of continuous AMS implementation. Patterns of antibiotic use underscore the need for further efforts on evidence-based antibiotic selection and for analyses on the appropriateness of antibiotic use. Full article

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.
