Does a quality management system improve quality in primary care practices in Switzerland? A longitudinal study.

Abstract

To examine the effectiveness of the quality management programme--European Practice Assessment--in primary care in Switzerland. Longitudinal study with three points of measurement. Primary care practices in Switzerland. In total, 45 of 91 primary care practices completed European Practice Assessment three times. The interval between each assessment was around 36 months. A variance analyses for repeated measurements were performed for all 129 quality indicators from the domains: 'infrastructure', 'information', 'finance', and 'quality and safety' to examine changes over time. Significant improvements were found in three of four domains: 'quality and safety' (F=22.81, p<0.01), 'information' (F=27.901, p<0.01) and 'finance' (F=4.073, p<0.02). The 129 quality indicators showed a significant improvement within the three points of measurement (F=33.864, p<0.01). The European Practice Assessment for primary care practices thus provides a functioning quality management programme, focusing on the sustainable improvement of structural and organisational aspects to promote high quality of primary care. The implementation of a quality management system which also includes a continuous improvement process would give added value to provide good care.
