Optimizing Antibiotic Prescribing for Acute Respiratory Tract Infections in German Primary Care: Results of the Regional Intervention Study CHANGE-3 and the Nested cRCT.

Within primary care, acute respiratory tract infections (ARTIs) are the most common reason for prescribing antibiotics. The aim of the CHANGE-3 study was to investigate how antibiotic prescribing for non-complicated ARTIs can be reduced to a reasonable level. The trial was conducted as a prospective study consisting of a regional public awareness intervention in two regions of Germany and a nested cluster randomised controlled trial (cRCT) of a complex implementation strategy. The study involved 114 primary care practices and comprised an intervention period of six winter months for the nested cRCT and two times six winter months for the regional intervention. The primary outcome was the percentage of antibiotic prescribing for ARTIs between baseline and the two following winter seasons. The regression analysis confirmed a general trend toward the restrained use of antibiotics in German primary care. This trend was found in both groups of the cRCT without significant differences between groups. At the same time, antibiotic prescribing was higher in routine care (with the public campaign only) than in both groups of the cRCT. With regard to secondary outcomes, in the nested cRCT, the prescribing of quinolones was reduced, and the proportion of guideline-recommended antibiotics increased.

[Acute respiratory tract infections and antibiotic prescriptions: What are patients' expectations?] / Akute Atemwegsinfekte und Antibiotikaverordnungen: Welche Erwartungen haben Patient*innen?

INTRODUCTION: The use of antibiotics in human medicine is partly responsible for the global increase in antibiotic resistance. Significant reductions in antibiotic prescribing were realised through educational campaigns, communication training and prescribing feedback. Based on data from the cluster-randomised CHANGE-3 trial, the present analysis focuses on the question of patient expectations for an antibiotic in acute respiratory infections. METHODS: 106 of 114 General Practitioner (GP) practices in Baden-Württemberg and Mecklenburg-Western Pomerania took part in the study. 4736 patients who visited the practices with acute respiratory infections from October 2018 to May 2019 filled out a questionnaire after the doctor's consultation. The analysis was descriptive. RESULTS: 16.7 % of patients with acute respiratory infections reported receiving antibiotics from their GP. 13.3 % of patients had hoped for an antibiotic and 5.5 % stated that they had asked their GP for an antibiotic prescription. The lowest prescription rate for antibiotics was reported by patients who had received a diagnosis of influenza from their GP. With specific diagnoses differentiated from uncomplicated respiratory tract infection, an increase in both the number of antibiotics hoped for and the number of antibiotics prescribed was observed. DISCUSSION: Patients still receive antibiotics more often than they actually hope for. On the part of GPs, prescriptions may still be written because of perceived pressure from patients, but this is not reflected in patient expectations. In addition to dealing openly with patients' expectations, strengthening patients' health literacy, mindful doctor-patient communication and offered opportunities for re-presentation in the case of specific diagnoses could further reduce the perceived pressure on GPs.

Converting habits of antibiotic use for respiratory tract infections in German primary care - study protocol of the cluster-randomized controlled CHANGE-3 trial.

BACKGROUND: The overuse of antibiotics is a major cause for the worldwide rise of antibiotic resistance. Although it is well known that acute respiratory tract infections (ARTI) are mainly caused by viruses and are often self limiting, antibiotics are too frequently prescribed in primary care. CHANGE-3 examines whether a complex intervention focusing on improving communication and provision of prescribing feedback reduces antibiotic use in patients suffering from ARTI. METHODS/DESIGN: The CHANGE-3 trial is a cluster-randomized controlled trial nested within a web-based public campaign conducted in two regions in Germany. A total of 114 medical practices will be included. Practices randomized to the intervention will receive a practice-specific antibiotic-prescription feedback and an educational outreach visit. During the visit the whole practice team will receive an introduction to e-learning modules addressing patient-centered communication on antibiotics. Furthermore, the practices will receive tablet PCs with information on antibiotics and the treatment of ARTI to be presented to patients. Practices randomized to the control will provide care as usual. The primary outcome measure is the antibiotic prescribing rate for patients with a history of ARTI. Data collected before the intervention, during the intervention and after the intervention will be compared. The use of narrow- vs. broad-spectrum antibiotics will be analyzed as a secondary outcome. A process evaluation is also part of the trial. DISCUSSION: This study should contribute to the growing body of research on reducing antibiotic prescription.
