Summary

Background: Inappropriate use of antibiotics is one of the main causes for the increase of antibiotic resistance strains. In Denmark general practice accounts for 90% of all prescribed antibiotics and one of the most common reasons for prescribing antibiotics is the suspicion of a urinary tract infection (UTI). The use of point-of-care test is meant to decrease the uncertainty about the bacterial origin of the symptoms; however, there is a paucity of knowledge about the validity of the different diagnostic approaches, thus impacting on the proper use of antibiotics.

Objective: To assess the diagnostic validity of different diagnostic approaches in patients with a suspected urinary tract infection and assess the impact on appropriate use of antibiotics.

Methods: 70 practices at the capital region will consecutively include 15-20 patients. The inclusion criteria of the patients comprise: a) Suspected Urinary tract infection, b) \> 18 years of age, c) patient consulting during office hours. Data at patient and GP level will be gathered.

16 diagnostic approaches will be compared and proper use of antibiotics will be assessed as a two-step process. The first step is the decision made during the consultation and the second step is the decision made after the consultation. Sensitivity, specificity and predictive values will be measure for each diagnostic approach using urine culture as a gold standard. The impact on proper use of antibiotics will be assessed in a hierarchical multivariable logistic model.
