Treatment Patterns and Adherence to Guidelines for Uncomplicated Urinary Tract Infection in Germany: A Retrospective Cohort Study.

ABSTRACT

INTRODUCTION: Understanding antibiotic prescribing for uncomplicated urinary tract infection (uUTI) could help to optimize management. However, data on uUTI treatment patterns in the European Union are scarce. We used real-world data to evaluate adherence to antibiotic prescribing guidelines for femalepatients with uUTI in Germany. METHODS: This retrospective cohort study used anonymized German statutory health insurance claims data from the Wissenschaftliches Institut für Gesundheitsökonomie und Gesundheitssystemforschung from January 2013 to December 2019. Patients were female, aged ≥ 12 years, with an index uUTI diagnosis. Patient characteristics and treating physician specialties were examined overall and in sub-cohorts for recommended/non-recommended treatment (based on initial therapy adherence to German uUTI treatment guidelines) and optimal/sub-optimal outcome (based on a prescription of different antibiotics or a urinary tract infection-related episode). RESULTS: Overall, 144,645 uUTI cases in 124,971 patients were analyzed; 51,230 (35.4%) and 93,415 (64.6%) cases were assigned to the recommended/non-recommended treatment sub-cohorts, respectively. Clinically meaningful differences in age and comorbidities were observed between these sub-cohorts. Most cases had an optimal outcome (n = 122,823; 84.9%); of these, a higher proportion received antibiotics that were recommended but not as first-choice versus first-choice therapies as their initial treatment (58.6% vs. 35.3%). In the sub-optimal outcome cohort, 49.1% received antibiotics that were recommended but not as first-choice and 41.1% received first-choice therapies as their initial treatment. Most uUTIs were treated by general practitioners (GPs; 82.3%), followed by gynecologists (13.3%), and urologists (6.8%). Notably, 64.5% of initial therapy prescriptions filled by gynecologists and 32.1% by GPs were first-choice antibiotics. CONCLUSION: A high proportion of prescribed treatments for the initial uUTI episode were not recommended by German uUTI guidelines as first-choice antibiotics. Prescribing adherence varied by physician specialty; specialists showed greater adherence to treatment guidelines versus GPs. This study provides a novel and multi-dimensional picture of uUTI treatment in Germany.

Uncomplicated urinary tract infections are one of the most common infections in women. Doctors around the world use different types of antibiotics to treat people with uncomplicated urinary tract infections. We performed this study to find out more about how doctors in Germany use antibiotics to treat uncomplicated urinary tract infections. We looked at health records from female patients (aged 12+) in Germany. Overall, we examined 144,645 records. We found that around one in ten women use antibiotics to treat an uncomplicated urinary tract infection every year. We then checked to see if the doctors were giving people the right type of antibiotic, the right dose, and the right length of course. To do this, we checked against guidelines that were written by experts in Germany. We found that only one in three patients (35%) received treatment that met the guidelines. We also looked to see what differences there were between different types of doctors. For example, if general practitioners (family doctors) used different antibiotics to specialist doctors in hospitals. Four out of five patients (82%) were treated by general practitioners. We found that specialists were more likely to stick to the guidelines than general practitioners. Finally, we looked at how many patients recovered well after their first course of antibiotics. More than four out of five patients (80%) recovered well. Interestingly, more than half of the patients who had a good recovery (59%) received antibiotics that were not recommended by the guidelines.
