Incidence of urinary tract infection among patients with type 2 diabetes in the UK General Practice Research Database...

The objective of this observational study was to quantify the incidence of urinary tract infections (UTI) among diabetes patients and compare this risk to patients without diabetes. Type 2 diabetes patients and a matched sample of patients without diabetes were identified from GPRD. Patients were followed for 1-year from their study index date until the first record of a UTI or a censored event. The incidence of UTI was 46.9 per 1000 person-years (95% confidence interval (CI) 45.8-48.1) among diabetes patients and 29.9 (95% CI 28.9-30.8) for patients without diabetes. Compared to the non-diabetes patients, the risk of UTI was 1.53 (95% CI 1.46-1.59) for all diabetes patients; and 2.08 (95% CI 1.93-2.24) for patients with previously diagnosed diabetes. In general practice, across gender and age, the risk of developing a UTI is higher for patients with type 2 diabetes compared to patients without diabetes.
