We used Medicare administrative data to examine trends in primary and revision total hip arthroplasty (THA) use and hospital volume. Between 1991 and 2005, primary and revision THA use increased by 40.9% and 16.8%, respectively. The percentage of primary THA procedures performed in high-volume hospitals (those in the highest quintile of volume) increased slightly from 58.0% of all procedures in 1991 to 58.7% in 2005 (P < .01). The percentage of revisions performed in high-volume hospitals increased from 60.9% to 62.4% (P < .01). The percentage of primary THA procedures performed by low-volume hospitals remained relatively stable (P = .36), whereas the percentage of revision THA performed by low-volume hospitals declined (P < .001). In aggregate, these results suggest minimal evidence that regionalization of THA is occurring.
我们使用医疗保险管理数据来研究初次和翻修全髋关节置换术(THA)使用和医院量的趋势。在 1991 年至 2005 年期间,初次和翻修 THA 的使用分别增加了 40.9%和 16.8%。在高容量医院(即处于量的最高五分位数的医院)进行的初次 THA 手术的百分比从 1991 年所有手术的 58.0%略有增加到 2005 年的 58.7%(P<.01)。在高容量医院进行的翻修手术的百分比从 60.9%增加到 62.4%(P<.01)。低容量医院进行的初次 THA 手术的百分比保持相对稳定(P=.36),而低容量医院进行的翻修 THA 手术的百分比下降(P<.001)。总的来说,这些结果表明,THA 的区域化几乎没有证据。
