Variations in elderly Medicare beneficiaries' health service use are examined using a 100-percent sample of fee-for-service (FFS) claims data from Alabama, Iowa, and Maryland. Provider specialty, group practice type, practice size, and location are found to be significant factors affecting hospital and ambulatory care utilization and cost, after controlling for patient and regional characteristics. These results provide insights into utilization and cost expectations from different types of primary-care gatekeepers as the Medicare managed care market develops.
利用来自阿拉巴马州、爱荷华州和马里兰州的100%按服务收费(FFS)索赔数据样本,对老年医疗保险受益人的医疗服务使用差异进行了研究。在控制了患者和地区特征后,发现医疗服务提供者的专业、团体执业类型、执业规模和地点是影响住院和门诊医疗利用及成本的重要因素。随着医疗保险管理式医疗市场的发展,这些结果为不同类型的初级保健守门人的利用和成本预期提供了见解。
