Abstract
Summary Parkinson’s disease (PD) is a common disorder that leads to severe disability, despite pharmacological and surgical interventions. As PD progresses, patients and their families experience substantial health and economic burdens. Little research has been conducted into the economic consequences of PD or the impairment of health dimensions, such as social function and mental health, that may accompany the deterioration in economic resources and physical function. may accompany the deterioration in economic resources and physical function. In the current study, the US National Medical Expenditure Survey (NMES) was examined as a source of population-based information about health-resource use, medical expenditures and health status. 43 patients with PD were identified, and each was matched with 3 individuals without PD to estimate the costs attributable to PD. Data from the NMES demonstrate the serious health and economic burdens of PD. The patients with PD were clearly shown to have decreased health status, increased health expenditures and lost productivity relative to controls. However, these estimates of the magnitude of disease burden must be used with caution. The small sample size appears to have inadequately represented patients in the earliest and the most advanced stages of PD. There was also considerable variability in case-control groups, resulting in wide confidence intervals for the estimates.
