An Analysis of the Effects of Organizational Strategies and Human Resource Management on the Quality of Life for Chinese Dementia Patients

Abstract

This study's objective was to evaluate if Parkinson's disease (PD) and depression are independent risk factors for dementia or whether they contribute to an overall elevated risk for dementia by working together. Methods. Patients who had just been diagnosed with Parkinson's disease, in addition to volunteers serving as controls, were selected at random from the database of the Taiwan National Health Insurance Research Center between the years of January 2001 and December 2008. This cohort was divided into three groups: controls, persons with Parkinson's disease alone, and people with Parkinson's disease plus depression. The controls may either have or not have depression. Using Cox's regression analysis, we were able to calculate the incidence rate of dementia for each group, in addition to the hazard ratio (HR).
