Quality improvement in chronic care by self-audit, benchmarking and networking in general practices in South Tyrol, Italy: results from an interventional study

Abstract

Background: Systematic strategies promoting quality of care in general practice are yet under-represented in several European countries.

Objective: This interventional study assessed whether a combined intervention (self-audit, benchmarking, quality circles) improved quality of care in Salzburg, Austria and South Tyrol, Italy. The present publication reports the Italian results.

Methods: We developed quality indicators for general practice in a consensus process based on pre-existing quality programmes. The indicators addressed diagnosis and treatment regarding eight common chronic conditions. A quality score comprising 91 indicators was calculated (0-5 points per indicator depending on fulfilment, maximum 455 points). We collected anonymous data from the electronic health records of the participating physicians in 2012, 2013 and 2014. Wilcoxon signed-rank tests were used for pre-post analysis.

Results: Thirty-six GPs participated in the study. The median quality score increased significantly from 177.0 points at baseline to 272.0 points at the second follow-up (P = 0.000). Improvements concerned process and intermediate outcome indicators particularly between baseline and the first follow-up.

Conclusion: Performance was relatively low at baseline and improved considerably, mainly in the first study period. The intervention investigated in this study can serve as a model for future quality programmes. A customized electronic health record for the implementation of this intervention as well as standardized and consistent documentation by GPs is a prerequisite. Use of a limited set of quality indicators (QIs) and regular QI modification is probably advisable to increase the benefits. Long-term prospective studies should investigate the impact of QI-based interventions on end-result outcomes.
