Are quality promotion initiatives in Austrian and Italian general practices associated with higher patient satisfaction and quality of life? Results from the interventional study 'IQuaB'

Abstract

The objective was to assess the changes in quality of life (QoL) and patient satisfaction of chronically ill patients in general practices in Salzburg (Austria) and South Tyrol (Italy) after implementation of a combined intervention addressing quality of care of general practitioners (GPs). Furthermore, the correlation between QoL/patient satisfaction and quality of care provided by the GPs (measured by a quality score based on quality indicators [QIs]) was investigated. The non-controlled pre-post study involved GPs and patients with chronic conditions. The intervention consisted of self-audit, benchmarking and quality circles. QIs were extracted in the participating practices in 2012 (preintervention) and 2014 (postintervention). Before and after the intervention, a patient survey was conducted including EQ-5D (measuring health-related QoL), a patient participation scale and parts of the European Task Force on Patient Evaluations of General Practice questionnaire (measuring patient satisfaction). Mann-Whitney U-tests, chi-square tests and Spearman's rank correlation were applied for statistical analysis. Fifty-six GPs participated in the study. 1,710 patients returned the questionnaire in 2012, and 1,374 in 2014. Mean EQ-5D index (QoL) was similar in Salzburg and South Tyrol in both years: 2012 Salzburg 0.85 (95% CI 0.84-0.87), South Tyrol 0.85 (95% CI 0.84-0.86); 2014 Salzburg 0.84 (95% CI 0.83-0.86), South Tyrol 0.84 (95% CI 0.83-0.86). Patient satisfaction was higher in Salzburg than in South Tyrol at baseline (EUROPEP: mean percentage of best response 61.5% vs. 49.1%, p < 0.000) and also at follow-up (61.9% vs. 49.2%; p < 0.000). No significant correlation between quality score and QoL/patient satisfaction was detected. Thus, the impact of the intervention was not significant within the intermediate time periods analysed in the study. Improvements in quality of care do not necessarily also improve patient-relevant outcomes, which are probably more associated with other factors than with medical quality (e.g. availability of the GP, waiting times and communication-related issues).
