Cost of hospitalization and length of stay in people with Down syndrome: evidence from a national hospital discharge claims database

Abstract

The present paper aims to describe the hospitalization profiles which include medical expenses and length of stays, and to determine their possible influencing factors of hospital admission on persons with Down syndrome in Taiwan. We employed a population-based, retrospective analyses used national health insurance hospital discharge data of the year 2005 in this study. Subject inclusion criteria included residents of Taiwan, and diagnosed with Down syndrome (ICD code is 758.0; N=375). Inpatient records included personal characteristics, admissions, length of stay, and medical expenses of study subjects. The results found that Down syndrome patients used 2 hospital admissions and their annual length of stay in hospital was 22.26 days, and the mean medical cost of admissions was 143,257 NT$. The admission figures show that Down syndrome individuals used two times of hospital days and nearly three times of medical expenses comparing to the general population in Taiwan. Finally, the multiple regression models revealed that factors of age, hold a serious illness card, low income family member, frequency of hospital admission, high medical expense user were more likely to use longer inpatient days (R2=0.36). Annual inpatient expense of people with Down syndrome was significantly affected by factors of severe illness card holder, low income family member, frequency of hospital admission and longer hospital stays (R2=0.288). Based on these findings, we suggest the further study should focus on the effects of medical problems among persons with Down syndrome admitted for hospital care is needed.
