For defining the health state of the population and demonstrating that computed general practice can be a preferential observation point for epidemiological study, we analyzed, as general practitioners, database of a dynamic cohort of 1501 subjects (m:724, f:777) living in Pavia and monitored from 1/1/1992 to 12/31/2001. In this paper we present mortality data compared to Italy in 1994. During the period, 209 deaths occurred (m:107, f:102). Differently from Italy, in Pavia cancer was the first cause of death in both sexes. When cardiovascular fatal events were analysed, age of death occurred 8.7 years in advance in males, while age of death for cancer was similar in both sexes. Sudden death represented one quarter of cardiovascular deaths. General practitioners' database can be an important and useful epidemiological source to detect areas with different risks of illness. Furthermore database offers the possibility to determine mortality rate for illness like sudden death not included in national statistical studies.
