Background: A number of dementia patients Is increasing rapidly to the aging society. As the age becomes higher, a variety of diseases are accompanied since most of the dementia patients are old, which may worsen their health condition more. This study was conducted to analyze the factors to affect the treatment result and prognosis by CCI of the dementia patients and to provide the government data for public health policies.
Methods: This study selected the dementia patients for five years from 2012 to 2016 as research subjects by using the Korea National Hospital Discharging Injury Survey Data of the Korea Disease Control and Prevention Agency. To understand the co-morbidity index, this study used the Charlson Comorbidity Index(CCI), and also conducted the Chi-squared test analysis and logistic regression analysis.
Results: By gender, dementia occurred women than men higher and was increased to be proportional with age. CCI was distributed from 0 to 13 scores, and the group with 1~2 scores were the most prevalent in both genders. Women were more common in the groups over 3 scores than men, however, men were more common the group with 7~9 scores. By result of treatment, improved cases were the most prevalent in both genders, and 23.8% out of expired cases was the group of CCI over 3 scores. A significant correlation was analyzed among gender, result of treatment, and after discharge. Women had a lower rate of improvement than men. And the higher CCI and age, the lower the rate of improvement.
Conclusions: Gender, age, and co-morbidity were high risk factors to show the differences of severity, and higher CCI showed the impact on the result of treatment and prognosis more negatively.
