Abstract
Modan, B. (Dept. Clinical Epidemiology, Chaim Sheba Medical Center,Tel-Hashomer, Israel), Leslau, V., Bott-Kanner,G., Barnoach, N., and Eliahou, H. E. Methodological problems in the estimation of maintenance dialysis needs. Int. J. Epid. 1972, 1 : 139–142. Estimates of needs for maintenance dialysis vary widely mostly due to the lack of universally accepted criteria for endstage kidney disease. Optimally, these estimates should be based on morbidity data in total communities, but even such an approach is liable to several methodological pitfalls. In Israel, a yearly dialysis rate of 82 new cases per million population in the 15–60 age group was estimated on the basis of a national morbidity study. Data obtained in the course of this study are used to point out some of the difficulties encountered in defining potential dialysis candidates. A more expedient method, based on the combination of death certificate screening and hospital record verification, is suggested for future estimates.
