BACKGROUND: The lifetime risk and expected cost of @entity130 care would be valuable for health policy planners, but this information is currently unavailable. The cumulative incidence rates methodology, based on a cross-sectional population analysis, offers an alternative approach to prohibitively costly prospective cohort studies. MATERIAL AND METHODS: Retrospective analysis of the California Office of Statewide Health Planning and Development (OSHPD) database was performed for 2008. @entity130 admissions were identified by ICD-9 primary diagnosis codes 800-959, with certain exclusions. Cumulative incidence rates were calculated as the cumulative summation of incidence risks sequentially across age groups. RESULTS: A total of 2.2 million admissions were identified, with mean age of 63.8 y, 49.6% @entity1 , 82.8% Whites, 5.7% Blacks, 11.3% Hispanics, and 3.1% Asians. The cumulative incidence rate for @entity1 older than age 85 y was 1119 per 10,000 @entity1 , with the majority of risk in the elderly, compared with 24,325 per 10,000 @entity1 for all-cause hospitalizations. The rates were 946 for @entity1 , 1079 for @entity1 , 999 for non-Hispanic Whites, 568 for Blacks, 577 for Hispanics, and 395 for Asians, per 10,000 population. The cumulative expected hospital charge was  6538, compared with  81,257 for all-cause hospitalizations. CONCLUSION: The cumulative lifetime risk of @entity130 requiring hospitalization for a @entity1 living to age 85 y in California is 11.2%, accounting for 4.6% of expected lifetime hospitalizations, but accounting for 8.0% of expected lifetime hospital expenditures. Risk of @entity130 is significant in the elderly. The total expenditure for all @entity130 hospitalizations in California was  7.62 billion in 2008.
