This study was conducted on the families and the patients registered to the FPMC in SNUH for Primary Care from September 1981 to June 1984.
The objectives of the study are to estimate the population at risk in FPMC(SNUH) and to compare it's demographic characteristics with Seoul population for the validity and then to evaluate the stability of the population at risk by continuity care.
Definition of terms was based on "International Classification of Health Problems in Primary Care - 2-Defined" Appendix II-International Glossary for Primary Care. The Age-Sex Registration by intent method was taken for the estimation of population at risk.
The results obtained were as follows:
