UNASSIGNED: Data was obtained from the Centers for Medicare and Medicaid Services (CMS) publicly available open payment datasets (2016-2019). Geographic locations were identified using regions as defined by the US Census Bureau. A linear regression was calculated to predict the open payment made based on the created variable region, the most used implant type (reverse vs anatomic, n > 30 to be included), and their hypothesized interaction.
UNASSIGNED: A significant regression equation was found for the hypothesized interaction between implant and region, F(13,11 186) = 3.446, P < .0001, with an R2 of 0.005. Within the regression, the implant type alone was not significantly related to the open payment (P = .070) but only became significant when paired with the region in the South (US$5807; P < .0001) and West (US$5638; P = .0012) compared to the Northeast.
UNASSIGNED: Our multivariate linear regression model revealed that reverse total shoulder implants were associated with higher open payments, but only within the South and West regions. This indicates that the contributions made by industry arthroplasty companies are a function of both implant and region.
■数据来自医疗保险和医疗补助服务中心(CMS)公开开放支付数据集(2016-2019)。使用美国人口普查局定义的区域确定地理位置。计算了线性回归,以预测基于创建的可变区域进行的公开支付,最常用的植入物类型(反向与解剖学,包括n>30),以及他们假设的互动。
■对于植入物和区域之间的假设相互作用,发现了一个重要的回归方程,F(13,11186)=3.446,P<.0001,R2为0.005。在回归中,仅植入物类型与公开付款没有显着相关(P=.070),但仅在与南部地区(5807美元;P<.0001)和西部地区(5638美元;P=.0012)配对时,与东北部地区相比才变得显着。
■我们的多元线性回归模型显示,反向全肩部植入物与较高的开放支付相关,但仅限于南部和西部地区。这表明工业关节成形术公司的贡献是植入物和区域的函数。
