Urine cultures and antibiotics for urinary tract infections in Dutch general practice.

Urine cultures were ordered in 17% (n=221) of patients, more frequently in high-risk patients (32%) than in low-risk patients (7%), for UTI complications (OR=6.4; 95% CI 4.6-9.0). In low-risk patients, 91% received antibiotics that were recommended in the guideline. For high-risk patients this percentage ranged widely, and was particularly low in the risk groups with signs of tissue invasion (29-50%). Diagnostic and therapeutic adequacy can still be improved by increasing the adherence to the guideline in UTI patients at high risk for complications. This may contribute to containing antibiotic resistance in UTI by ordering urine cultures and use the results to adjust prescriptions to antibiotic susceptibility of the uropathogen.
