概括
医疗补助扩张增加了医疗补助资助的关节整形手术 (TJA) 的数量,包括关节整形手术 (THA) 和膝关节整形手术 (TKA). 然而,TJA的整体利用率没有显著变化,这表明资金来源发生了转变,而不是程序增加.
科学领域:
- 卫生经济学 卫生经济学
- 医疗保健服务研究 医疗服务研究
- 整形外科手术 整形外科手术
背景情况:
- 关于医疗补助扩张对整体关节整形术 (TJA) 使用的影响,存在相互矛盾的文献.
- 一些研究表明外科医生接受医疗补助的比例没有增加,而另一些研究则通过有限的分析表明医疗补助资助的TJA的增长.
研究的目的:
- 确定医疗补助扩张是否影响了医疗补助资助和所有资金来源的关节整形术 (THA) 和膝关节整形术 (TKA) 的利用.
- 进行一项全国性的多保险,计量经济学研究,研究TJA利用率在医疗补助后的扩张.
主要方法:
- 从2010年到2017年,利用了999,015个THA和2,099,975个TKA案件的国家付款人数据库.
- 采用差异分析和事件分析来评估医疗补助扩张对TJA利用的影响,并确认并行趋势.
主要成果:
- 医疗补助资助的THA利用率增加了40.4% (P = .001),而医疗补助资助的TKA使用率增加了35.8% (P < .001).
- 所有资金来源的THA (4.6%,P = .128) 或TKA (3.4%,P = .321) 的利用没有显著增加.
- 事件分析证实了前扩张时期的平行趋势.
结论:

Ankle Joint
1.6K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
