Population-Based Analysis of Incidence Rates of Cancer and Noncancer Chronic Diseases in the US Elderly Using NLTCS/Medicare-Linked Database

Table 4

Age-adjusted incidence rates per 100,000 under alternative approaches to the definition of age at onset. Standard calculation (V0) of age-adjusted incidence rates (per 100,000) was performed according to the aforementioned rules, that is, screener NLTCS population, using the NLTCS weights, the 4 basic Medicare sources, only the primary diagnosis, at least two records (or death) in years, with cut on frequency of HMO coverage , age standardization using standard population of 1994. Other calculations are (V1) no age standardization; that is; age specific rates are averaged using population of respective year; (V2) No NLTCS weights; (V3) alternative censoring strategy; (V4) ; (V5) ; (V6) all Medicare sources; (V7) years; (V8) no requirement for codes to be primary; (V9) no requirement of the second record (Algorithm B); (V10) no requirement from both V8 and V9 (Algorithm C); (V11) McBean’s approach; and (V12) no death as a second event (Algorithm D).
