Chronic pain is one of the most common chronic conditions affecting more than 50 % of older adults. While pain management can be quite complex, prescription drugs are the most commonly used treatment modality. In this study, I examine whether increased access to prescription drugs due to the introduction of the Medicare Part D program in 2006 led to better management of pain among the elderly. While prior work has identified increases in the utilization of analgesics due to the introduction of Medicare Part D, the extent to which this increase in drug use actually improved the well-being of older adults is not known. Using data from the Health and Retirement Study, I employ a difference-in-differences strategy that compares pre versus post 2006 changes in pain related outcomes between Medicare eligible persons and a younger ineligible group. I find that Medicare Part D significantly reduced pain related activity limitations among a sample of older adults who report being troubled by pain.
慢性疼痛是影响超过50%老年人的最常见慢性病之一。虽然疼痛管理可能相当复杂,但处方药是最常用的治疗方式。在本研究中,我考察了2006年引入医疗保险D部分计划后,处方药获取的增加是否导致老年人的疼痛得到更好管理。虽然先前的研究已经确定,由于医疗保险D部分的引入,镇痛药的使用有所增加,但这种药物使用的增加实际上在多大程度上改善了老年人的健康状况尚不清楚。利用健康与退休研究的数据,我采用了一种差异中的差异策略,比较了医疗保险合格人群和较年轻的不合格人群在2006年前后疼痛相关结果的变化。我发现,医疗保险D部分显著减少了在报告受疼痛困扰的老年人群样本中与疼痛相关的活动限制。
