Applicability of Outpatient Quality Indicators for Appropriate Antibiotic Use in a Primary Health Care Area: a Point Prevalence Survey
Abstract
The ability to measure the quality of antibiotic prescriptions is a critical element in all antimicrobial stewardship programs. The aims of the present study were to evaluate the clinimetric properties of 32 recently developed outpatient quality indicators (OQIs) and to identify potential room for improvement in antibiotic use in a primary health care (PHC) area. The study was performed in a PHC area in Barcelona, Spain with 260,657 inhabitants, nine PHC centers, and a 400-bed acute-care teaching hospital. We selected 9 of the 32 OQIs that were applicable to our PHC area and evaluated them for measurability, adherence, and room for improvement. Nonmeasurable OQIs, OQIs without room for improvement, and OQIs beyond the scope of the PHC antimicrobial stewardship program were excluded. Data from 260,561 registered patients were assessed. Measurability was high for all OQIs except those that required manual recording of the clinical diagnosis (OQIs on group A streptococcal diagnostic testing). Adherence to guidelines was poor for most OQIs, but particularly for the indicator on the avoidance of antibiotics for viral or self-limiting bacterial infections, where we observed more than 60% room for improvement for both acute tonsillitis and sinusitis. The QIs evaluated were applicable to clinical practice and proved useful for identifying areas with room for improvement in our setting and for guiding the design of future interventions with specific objectives.
