Prof. MD PhD K.J. Jager (Evaluation of Health Care and Epidemiology of Kidney Disease)

Evaluation of Health Care

Within this research theme there is a strong focus on clinical performance indicators and on their use for (inter)national benchmarking and improvement of quality of care. Research subjects include the selection and standardization of clinical performance indicators within nephrology (NephroQUEST project - Public Health Programme EC)


Here there is a primary focus on the domain of nephrology. Different studies concentrate on factors determining the trends and international differences in the prevalence of chronic kidney disease (CKD) and the incidence of end-stage renal failure (ESRD) and related patient outcomes. This aetiologically oriented research aims to identify the determinants of these trends and differences, for example co-morbidity, residual renal function, treatment, general population mortality, timing of transplantation but also the effects of non-medical (e.g. economic) factors. Other subjects include the comparison of conservative and novel statistical methods.
