Quality of chronic care in general practices in Salzburg, Austria, and South Tyrol, Italy: a comparative process of care intervention study

Abstract

Background: Quality indicators to assess the quality of primary care have only been applied on a national or regional level in European countries, and there have been no comparisons between regions of different countries. In the interventional pre-post-study "Improvement of Quality by Benchmarking - IQuaB" (level of evidence: 3), we aimed to improve and compare quality of process care in 57 participating general practices in Salzburg, Austria, and South Tyrol, Italy.

Methods: The intervention consisted of self-audit, benchmarking and quality circles. Quality indicators for eight common chronic diseases (e. g., diabetes) were extracted from the electronic health records in 2012, 2013 and 2014. Based on 19 quality indicators, a supra-regional quality score was calculated and compared using Mann-Whitney U tests.

Results: A relatively weak baseline performance was identified in both regions. In all three assessments, the median quality score increased in both regions and was significantly higher in South Tyrol than in Salzburg. During the study period the median supra-regional quality score increased from 20.00 to 38.00 in the Salzburg sample and from 47.00 to 79.50 in the South Tyrolian sample. The differences between the two regions were significant at baseline and after intervention (2012: p=0.015, 2014: p=0.001).

Discussion: Despite data extraction challenges in Austria, we are convinced that our data highlight real differences in (processual) quality of care between the two regions.

Conclusions: The reasons underlying the persisting differences between the two regions may include: (1) different functions in electronic health records, (2) benchmarking as an integral part of the electronic health record, (3) gate-keeping system and use of registration lists, (4) state-supported quality initiatives.
