    UTI-IPD – Strategies to reduce antibiotic use in women with uncomplicated urinary tract infection – an individual-patient-data meta-analysis (IPD-MA)

    Uncomplicated urinary tract infection in women is one of the most common reasons for presenting in ambulatory care and causes high rates of antibiotic prescription. Treatment approaches to reduce antibiotic use were tested in several randomised controlled trials.

    In the meta-analysis of individual patient data, we will estimate the effect of the therapeutic strategies to reduce antibiotic consumption compared to immediate antibiotic treatment. Furthermore, we aim to identify prognostic factors and moderators of different courses of disease to develop a clinical prediction model for general practice.

    Studies included in this project compare and contrast different treatment strategies (analgesics, phytotherapeutics, delayed antibiotic prescriptions and placebo) with immediate antibiotic treatment. Individual patient data allow the differentiated analysis of effects of non-antibiotic strategies compared to antibiotic treatment. Furthermore, differences between particular treatment strategies can be compared. In total, IPD of nine trials meeting the inclusion criteria could have been extracted and are currently analysed.
