Background: Multimorbidity is common health condition especially in the older population and associated with high levels of healthcare utilization and costs. But little is known about its frequent patterns and association with healthcare utilization or cost in Korea. The purpose of this paper is to investigate the prevalent combinations of common chronic conditions and their effect on healthcare cost and to find out target groups for an intervention to relieve disease burden.
Methods: We analyzed the Korea Health Panel Data representing non-institutionalized Korean adult populations aged 20 and over with chronic conditions. Also we identified the most prevalent combinations of common chronic conditions and estimated their mean and total healthcare cost for the elderly and nonelderly patients.
Results: The most common dyad and triad of chronic conditions for the nonelderly patients are hypertension-diabetes(3.6%), hypertension-arthritis-osteoporosis(0.9%) and for the elderly are hypertension-arthritis(8.6%), hypertension-hyperlipidemia-arthritis(3.1%). The most burdensome combinations for the nonelderly are asthma-COPD, hypertension-arthritis-diabetes and for the elderly are hypertension-arthritis, hypertension-hyperlipidemia-arthritis(dyad and triad, respectively)
Conclusion: Our findings suggest that national strategy and intervention for chronic diseases should place the priority to the multimorbid population causing the highest medical cost.
