Objectives: The capability to measure and monitor the quality of antibiotic prescribing is an important component of antibiotic stewardship (ABS) programmes. Several catalogues of consensus-based structure and process-of-care quality indicators (QIs) have been proposed, but only a few studies have tested and validated ABS QIs in practice tests. This multicentre study determined the clinimetric properties and suitability of a set of 33 process QIs for ABS that had earlier been developed and in part recommended in a German-Austrian hospital ABS practice guideline., Methods: Two point prevalence surveys were conducted in a convenience sample of 24 acute care hospitals throughout Germany, and data of all screened adult inpatients with prescription of a systemic antibiotic at a given day (n=4310) were included in the study. For each QI, the following clinimetric properties were assessed: applicability, feasibility, performance, case mix stability and interobserver reliability., Results: Eighteen QIs were considered sufficiently feasible, applicable and reliable, and had adequate room for improvement. The finally selected QIs primarily cover antibiotic therapy of common infections (bloodstream infection, pneumonia and urinary tract infection), while two of the QIs each address surgical prophylaxis and general aspects of antibiotic administration., Conclusions: Practice tests may be important to test the suitability of consensus process-of-care QIs in the field of hospital ABS. The 18 selected QIs considered suitable enough for hospital ABS in this study should be regarded as priority QIs useful for internal quality control and assurance. More research and additional practice tests may be needed to confirm their suitability for external quality assessment schemes., (© The Author(s) 2019.

Purpose: Simple, valid, and evidence-based indicators to measure the quality of antimicrobial prescribing in acute-care hospitals are urgently needed and increasingly requested by policymakers. The aim of this study was to develop new consensus quality indicators (QIs) for hospital antibiotic stewardship (ABS) and infection management which will be further evaluated for internal quality management and external quality assessment in Germany., Methods: Based on an extensive literature review, the Austrian-German hospital ABS Guideline Committee and selected members of the German ABS Expert Network discussed and drafted a list of 99 potential indicators for hospitals that reflect structural prerequisites for ABS (35 items), ABS core activities (18 items), additional ABS measures (5 items), and process of care indicators (both generic and disease-specific-12 and 29 items, respectively). Questionnaires were mailed to German ABS experts and healthcare professionals with further education in ABS. Participants scored (on a nine-point Likert scale) relevance (clinical, ecological/resistance, economical/expenses) and presumed practicability (six categories: clarity of definition, effort to collect data, barrier to implementation, verifiability, suitability for external quality assessment, quality gap), taking into account their local work environment. The scores were processed according to the RAND/UCLA appropriateness method, and QIs were judged relevant if the median (clinical + ecological and/or economical) scores were >6. The indicators thus assessed to be potentially relevant were then filtered according to their practicability. Highly relevant QIs with borderline practicability scores and items with disagreements and overlapping areas were re-discussed in a final multidisciplinary panel consensus workshop convened in November 2012., Results: Of the 340 questionnaires that were mailed, 75 questionnaires were completed and returned. Of 99 initially proposed items, 32 were excluded due to insufficient scores. Of the remaining 67 items, 21 structural and 21 process of care QIs were finally selected, including four QIs with high clinical and ecological but limited economical relevance, and three QIs with high clinical and economical but limited ecological relevance. Among the selected QIs, efforts to collect data and implementation barriers were scored as suboptimal in many cases., Conclusions: A catalog of consensus structural and process of care ABS-QIs was established. These should undergo further pilot and feasibility studies in the German hospital healthcare sector. The panelists were most critical regarding resource use/complexity issues and presumed implementation barriers. How this may limit applicability of QIs remains to be determined.

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.

Background: A previous study from Germany showed high antibiotic use in university hospitals, particularly in intensive care units (ICU) and hematology-oncology services, but there has been no information about recent antibiotic use in non-university hospitals. In the present study, we collected data from 40 non-university regional general hospitals located in the southwestern part of the country, and analyzed use density in the medical and surgical services of these hospitals. Materials and Methods: Hospital pharmacy records for the calendar years 2001 and 2002 were evaluated. The number of defined daily doses (DDD, definition according to the WHO/ATC 2001 index) and prescribed daily doses (PDD) per 100 patient days (DDD/100 or PDD/100, respectively) were calculated to compare antibiotic use densities in medical and surgical services. Data for surgery included various subspecialties and gynecology. Results: Antibiotic use in the participating hospitals increased minimally between 2001 and 2002 both in medicine as well as in surgery. Use density in internal medicine (ICU areas excluded) in the year 2002 ranged between 13.5 and 93.7 DDD/100 with a weighted mean of 49.9 DDD/100 (corresponding to 28.6 PDD/100, respectively). Values for surgery were lower with a weighted mean of 43.4 DDD/100 (corresponding to 26.1 PDD/100, range, 10 to 65.4 DDD/100), respectively. Hospital size was not a strong predictor of use density, while large differences were observed between intensive care areas and normal wards. Mean use densities in intensive care areas in 2002 were 105.6 DDD/100 (or 49.7 PDD/100) in medical intensive care units, 116.9 DDD/100 (or 61.2 PDD/100) in surgical intensive care units, and 112.7 DDD/100 (or 66.7 PDD/100) in mixed, interdisciplinary intensive care units. Betalactams made up > 50% of all PDDs, while fluoroquinolones were the second most frequently prescribed drugs (15% of all PDDs). Fluoroquinolones were usually given orally. Overall glycopeptide and aminoglycoside use was < 1 PDD/100. Conclusion: This recent data from a large regional nonuniversity acute care hospital sample confirms that hospital antibiotic use density largely depends on patient care areas and less on hospital size. Surprisingly low use was observed for glycopeptides and aminoglycosides. The data may be useful as a benchmark for further pharmacoepidemiologic evaluation and focused drug use control interventions.
