This article in the supplement on the Performance, Effectiveness, and Costs of Treatment episodes (PERFECT)-project describes the PERFECT Hip and Knee Replacement Database and its possibilities by evaluating regional and hospital-level differences in length of stay (LOS), costs and complication rates of total hip arthroplasty (THA) and total knee arthroplasty (TKA) in Finland.
All hip and knee arthroplasties are recorded in the Finnish Hospital Discharge Register (FHDR) and Finnish Arthroplasty Register (FAR). LOS, length of uninterrupted institutional care (LUIC), complication rates and other parameters of treatment were determined by region and hospital during 1998-2008 based on these.
LOS and LUIC following THA and TKA diminished during the follow-up period. In 1998 average LOS after THA and TKA was 9.9 and 10 days. In 2008, these had shortened to 5.2 and 5.3 days, respectively. There was a 5.0 and 7.5 percentage point difference in revision rate between regions in THAs and TKAs, respectively, performed during 2005-2007 and followed to the end of 2009.
The Finnish health care registers provide a monitoring system for evaluating hospital- and regional-level differences in THA and TKA. The differences in LOS, LUIC and revision rates between hospitals and regions are considerable.
本文是 PERFECT 项目中关于治疗结果、效果和成本的补充部分，介绍了 PERFECT 髋关节和膝关节置换数据库及其可能性，通过评估芬兰全髋关节置换术（THA）和全膝关节置换术（TKA）的住院时间（LOS）、成本和并发症发生率的地区和医院差异来实现。
所有髋关节和膝关节置换术都记录在芬兰住院患者登记系统（FHDR）和芬兰关节置换登记系统（FAR）中。根据这些数据，确定了 1998-2008 年期间各地区和医院的 LOS、无间断医疗机构护理（LUIC）长度、并发症发生率和其他治疗参数。
THA 和 TKA 后的 LOS 和 LUIC 在随访期间逐渐减少。1998 年，THA 和 TKA 后的平均 LOS 分别为 9.9 和 10 天。2008 年，这一数字分别缩短至 5.2 和 5.3 天。在 2005-2007 年进行并随访至 2009 年底的 THA 和 TKA 中，地区间翻修率分别存在 5.0 和 7.5 个百分点的差异。
芬兰医疗保健登记系统提供了一个监测系统，用于评估 THA 和 TKA 的医院和地区差异。医院和地区之间在 LOS、LUIC 和翻修率方面的差异相当大。
