Public Health Triangulation to inform decision-making in Belgium.

We assessed the impact of a nation-wide ambulatory care complex intervention (the "care trajectory program") on quality of care in Belgium. We used the three-step public health triangulation method described in this paper and data from four different data sources: a national reimbursement database, an electronic patient record-based general practitioner network, the Belgian general practitioner sentinel network, and a new national registry for care trajectory patients. By applying our method and using the available evidence, we identified key findings that have been accepted by experts and stakeholders.

EPR-based, quality-related process parameters: a nationwide assessment.

The aim of the study was to determine whether or not primary care EPR-based data can be used to measure specific process parameters that can then, in turn, be used to assess the quality of care provided to chronic patients. We analysed data from a large research network that collects data from all Belgian GP practices through both manual and automatic extraction procedures. We built a number of quality-related process parameters and observed the concordance of our results with two external databases: a nationwide reimbursement database and a regional EPR-based network.

Belgian primary care EPR: assessment of nationwide routine data extraction.

Starting in 2009, the first ever Belgian nationwide data collection network using routine data extracted from primary care EPR (upload method) has been built from scratch. The network also uses a manual web-based data collection method. This paper compares these two methods by analysing missing and most recent values for certain parameters.

Nation-wide primary healthcare research network: a privacy protection assessment.

Efficiency and privacy protection are essential when setting up nationwide research networks. This paper investigates the extent to which basic services developed to support the provision of care can be re-used, whilst preserving an acceptable privacy protection level, within a large Belgian primary care research network. The generic sustainable confidentiality management model used to assess the privacy protection level of the selected network architecture is described.
