This study aims to explore the medical needs of patients who have different combinations of multiple chronic diseases in order to improve care strategy for chronic patients. This study was based on a national probability proportional to size (PPS) sampling to older adults over 50 years old. We collaborated the files of the 2000-2001 health insurance claims and selected 8 types of common chronic diseases among seniors, for the discussion of multiple combinations of chronic diseases, including hypertension, diabetes, heart disease, stroke, dementia, cancer, arthritis and chronic obstructive pulmonary disease. Among the NHI users, there are 50.6% of the cases suffering from at least one chronic disease, 27.3% suffering from two types of chronic diseases and above. From possible combinations of eight common chronic diseases, it is found hypertension has the highest prevalence rate (7.5%); arthritis ranks the next (6.2%); the combination of hypertension and heart disease ranks the third (3.4%). In the 22 types of major chronic disease clusters, the average total medical expense for people who have five or more chronic diseases ranks the highest, USD 4465; the combination of hypertension, diabetes, heart disease, and arthritis ranks the next, USD 2703; the combination of hypertension, diabetes, and heart disease ranks the third, USD 2550; cancer only ranks the fourth, USD 2487. Our study may provide statistical data concerning co-morbidity among older adults and their medical needs. Through our analysis, the major population that exhausts the medical resources may be discovered.
