ABSTRACT
BACKGROUND: Antimicrobial stewardship (AMS) programs are effective tools for improving antibiotic prescription quality. Their implementation requires the regular surveillance of antibiotic consumption at the patient and institutional level. Our study captured and analyzed antibiotic consumption density (ACD) for hospitalized pediatric patients. METHOD: We collected antibacterial drug consumption data for 2020 from hospital pharmacies at 113 pediatric departments of acute care hospitals in Germany. ACD was calculated as defined daily dose (DDD, WHO/ATC Index 2019) per 100 patient days (pd). In addition, we analyzed the trends in antibiotic use during 2013-2020. RESULTS: In 2020, median ACD across all participating hospitals was 26.7 DDD/100 pd, (range: 10.1-79.2 DDD/100 pd). It was higher at university vs. non-university hospitals (38.6 vs. 25.2 DDD/100 pd, p < 0.0001). The highest use densities were seen on oncology wards and intensive care units at university hospitals (67.3 vs. 38.4 DDD/100 pd). During 2013-2020, overall ACD declined (- 10%) and cephalosporin prescriptions also decreased (- 36%). In 2020, cephalosporins nevertheless remained the most commonly dispensed class of antibiotics. Interhospital variability in cephalosporin/penicillin ratio was substantial. Antibiotics belonging to WHO AWaRe "Watch" and "Reserve" categories, including broad-spectrum penicillins (+ 31%), linezolid (+ 121%), and glycopeptides (+ 43%), increased over time. CONCLUSION: Significant heterogeneity in ACD and prescription of different antibiotic classes as well as high prescription rates for cephalosporins and an increased use of reserve antibiotics indicate improvable antibiotic prescribing quality. AMS programs should urgently prioritize these issues to reduce antimicrobial resistance.
ABSTRACT
BACKGROUND: There is much discussion about which measure or bundle of measures is most efficient in hospital antibiotic management programs, and it is often unknown which parts of such programs are readily available. The ABS International group conducted a survey to estimate the prevalence and characteristics of country-specific hospital antibiotic management programs and program components. This paper summarizes the results for Germany. METHODS: The survey was conducted in April and May 2007. A questionnaire with various items related to hospital antibiotic management including control of consumption and availability of diagnostic microbiology was sent to hospital pharmacists through the ADKA (Bundesverband Deutscher Krankenhausapotheker). The questionnaires were analyzed by calculating mean scores for the various items and topics. MAIN FINDINGS: Of 400 questionnaires sent, 48 were returned and evaluable. Most respondents represented general hospitals in the southern part of Germany. Items that scored high were related to frequency of evaluation of antibiotic resistance data (4.48), availability of (simple) management tools for antibiotic prescribing (4.05), and control of antibiotic consumption (4.02). Items related to the availability of trained and dedicated antibiotic management officers scored very low. CONCLUSIONS: Shortage of trained and dedicated personnel may limit the organization of effective antibiotic management in many German hospitals.
