Prof. PhD N.F. de Keizer (Evaluation of health care and health care information)

Within my research group 3 research lines can be distinguished:

1) Evaluation of quality of health care

2) Evaluation of health care information systems

3) Terminological systems

Ad 1) Most of my research is related to the Nationale Intensive Care Evaluation (NICE) registry. This registry contains case mix and outcome data of more than 80 Dutch ICUs. The goal of NICE is to assess and improve the quality of Dutch ICUs and to perform epidemiological research. Institutional comparison based on case-mix adjusted outcome plays an important role. All aspect that are important to continuously monitor quality of care by a national registry are part of this research line. Case-mix correction, prognostic models, benchmarking, quality indicators, feedback, quality of data are subjects of investigation.

Ad 2) This research line has an local, national and an international part. Within the AMC several evaluation projects of new information technologies have been running, e.g. evaluation of  the (cost) effectiveness of teledermatology, evaluation of decision support systems in the intensive care for tidal volume, glucose regulation and medication prescription. On a national level a decision support system for cardiac rehabilitation has been evaluated on adherence to a national guideline. As a follow up a multifaceted intervention including feedback and educational outreach visits next to the decision support is evaluated. As the (former) chair of the International Medical Informatics Association working group on health technology assessment I was involved in the development of guidelines for planning, developing and reporting evaluation studies in health informatics. Furthermore, I supervise evaluation projects of EMRs implemented in Kenya and Uganda.

Ad 3) More and more health institutions are implementing electronic patient records. Ultimately data recorded in the electronic patient record can be reused for quality assurance (see point 1), research, management information, decision support, financial reimbursement. This is only possible when data is recorded in a detailled but also structured and standardized way. To enable standardized data entry terminological systems are essential. This research line is lead by Ronald Cornet and corporates with national and internation standardisation organisations such as the Dutch ICT Institute in health care (NICTIZ); SNOMED international NFU program  "Eenmalige registratie bij de bron" and GoFAIR foundation.
