BACKGROUND
The objective of this study was to ascertain co-occurring chronic conditions and expenditures associated with Parkinson's disease among elderly individuals (age ≥ 65 years).
METHODS
A retrospective, cross-sectional matched case-control design with data from Medical Expenditure Panel Survey (MEPS), a nationally representative survey of households in the United States was used. Elderly with Parkinson's disease (N = 350) were compared to a matched control group (N = 1050) based on propensity scores. Ordinary Least Squares regressions on logged dollars were performed to understand the association between Parkinson's disease and expenditures. All analyses accounted for the complex survey design of the MEPS and were conducted in SAS 9.3.
RESULTS
Among elderly, the average total expenditures were $15,404 for those with Parkinson's disease and $13,333 for those without Parkinson's disease. Results from regressions revealed that elderly with Parkinson's disease had 109% greater total expenditure compared to those without Parkinson's disease, when only demographic and socioeconomic variables were entered in the model. When co-occurring chronic conditions were additionally included in the model, those with Parkinson's disease had 84% greater expenditures compared to those without Parkinson's disease.
CONCLUSIONS
Excess expenditures associated with Parkinson's disease are partially driven by co-occurring conditions among individuals with Parkinson's disease.
背景
本研究旨在确定与老年人群（年龄≥65 岁）帕金森病相关的共病慢性疾病和支出。
方法
本研究采用回顾性、横断面匹配病例对照设计，使用来自美国家庭的全国代表性调查医疗支出面板调查（MEPS）的数据。根据倾向评分，将帕金森病患者（N=350）与匹配对照组（N=1050）进行比较。使用对数美元进行普通最小二乘回归，以了解帕金森病与支出之间的关系。所有分析均考虑了 MEPS 的复杂调查设计，并在 SAS 9.3 中进行。
结果
在老年人中，帕金森病患者的平均总支出为 15404 美元，无帕金森病患者的平均总支出为 13333 美元。回归结果显示，仅纳入人口统计学和社会经济变量时，帕金森病患者的总支出比无帕金森病患者高 109%。当将共病慢性疾病额外纳入模型时，帕金森病患者的支出比无帕金森病患者高 84%。
结论
帕金森病相关的超额支出部分是由帕金森病患者共病引起的。
