Medicare Managed Care Spillovers and Treatment Intensity
研究发现，地区内医疗保险管理式医疗参保比例上升会降低传统按服务付费的急性心肌梗死患者的治疗成本和强度，包括减少手术再灌注和机械通气使用。
Evidence suggests that the share of Medicare managed care enrollees in a region affects the costs of treating traditional fee-for-service (FFS) Medicare beneficiaries; however, little is known about the mechanisms through which these 'spillover effects' operate. This paper examines the relationship between Medicare managed care penetration and treatment intensity for FFS enrollees hospitalized with a primary diagnosis of AMI. I find that increased Medicare managed care penetration is associated with a reduction in both the costs and the treatment intensity of FFS AMI patients. Specifically, as Medicare managed care penetration increases, FFS AMI patients are less likely to receive surgical reperfusion and mechanical ventilation and to experience an overall reduction in the number of inpatient procedures.
