Complete Prevalence (ComPrev) Software

Version 1.0 released August 2005

The ComPrev software calculates complete prevalence based on limited-duration prevalence statistics. Complete prevalence represents the proportion of people alive on a certain day who previously had a diagnosis of the disease, regardless of how long ago the cancer was diagnosed. The software contains incidence and survival models estimated using SEER cancer data for a combination of cancer sites, sex and races. These models are used to calculate the completeness index (Capocaccia & De Angelis, 1997; Merrill et al., 2000). The completeness index represents the percent of "completeness" of limited duration prevalence. For example, 90% indicates that limited duration prevalence represents 90% of complete prevalence. Complete prevalence is calculated by dividing limited duration prevalence by the completeness index as a proportion. Limited-duration prevalence statistics can be extracted from SEER*Stat software and imported into ComPrev.
