- hypothesisN/A
- Healt Condition(s) or Problem(s) studiedUrinary tract infections
- Inclusion criteriaHospitals will be randomized.
For baseline- and postintervention measurement data will be extracted from medical charts of patients.
Inclusion criteria for these patients are:
1. In- and outpatients from the departments Urology or Internal Medicine;
2. > 16 years;
3. Diagnosed and treated for a complicated UTI in 2008 (2007).
- Exclusion criteria1. No (treated) UTI;
2. Uncomplicated UTI;
3. Nephro drain;
4. JJ catheter;
5. < 16 years;
6. Diagnosed and treated for a complicated UTI before 2007.

- InterventionsAfter a baseline measurement, hospitals will be randomized between two implementation strategies: a theory-based and effective, but labour-intensive strategy (the 'state-of-the-art' strategy) versus a currently popular strategy of providing public comparative information on quality of antibiotic care (the 'public reporting' strategy). In a post-intervention measurement, quality of antibiotic use will be assessed again for these departments.
- Primary outcomeQuality of antibiotic use (measured by clinically validated indicators).
- Secondary outcome1. Cost-effectiveness;
2. Successful elements of the implementation strategy.
- Timepoints1. Baseline measurement (Jan-August 2009);
2. Post-intervention measurement (Nov 2010-May 2011).

- Brief summaryTo improve appropriate use of antibiotics in UTI, implementation of the national guideline is necessary. In our previous study on the quality of UTI care in four Dutch hospitals, which we can consider as a pilot study for this study, we systematically developed quality indicators extracted from the national guideline. These were subsequently tested in four different Dutch hospitals. The indicators showed poor adherence to the guideline and a large room for improvement.

This study evaluates the cost-effectiveness of two strategies to improve adherence to the UTI guideline. It is a cluster-randomized controlled trial, including patients with complicated UTIs from two departments (Internal Medicine and Urology) in 19 participating hospitals. After a baseline measurement in 50 patients from each department (1900 patients), using clinically validated indicators, hospitals will be randomized between two implementation strategies. A theory-based and effective, but labour-intensive strategy (the 'state-of-the-art' strategy) is compared to a currently popular strategy of providing public comparative information on quality of antibiotic care (the 'public reporting' strategy). In a post-intervention measurement, quality of antibiotic use will be assessed again for these departments (1900 patients). Effectiveness of the two implementation strategies will be evaluated using multilevel linear regression analysis, adjusting for the hierarchical structure (patients within departments and departments within hospitals) in the data. Data will be extracted from medical charts of patients.
