Providing physical therapy service on Sundays is a much debated topic among hospital administrators. The purpose of this study was to determine if 7 days per week of physical therapy coverage results in shorter lengths of stay and differing discharge status than 6 days per week. A total of 140 subjects with hip or knee arthroplasty participated; there were 80 in the 6-day groups and 60 in the 7-day groups. Data on postoperative length of stay, discharge destination, and discharge disposition were collected by retrospective medical record review. The Mann-Whitney U test was used to test for differences in length of stay data, and the chi-squared test was used to test for differences in discharge disposition and discharge destination. No significant differences in postoperative length of stay, discharge destination, nor discharge disposition existed between the 6- and 7-day physical therapy coverage hip or knee arthroplasty groups. However, the power of the statistical tests applied was low. This study provides no evidence that 7-day per week physical therapy results in shortened postoperative length of stay, differing discharge destination, nor differing discharge disposition for patients undergoing hip or knee arthroplasty.
在周日提供物理治疗服务是医院管理人员中一个备受争议的话题。本研究的目的是确定每周7天的物理治疗覆盖是否比每周6天导致更短的住院时间和不同的出院状态。共有140名接受髋关节或膝关节置换术的受试者参与；6天组有80人，7天组有60人。通过回顾性病历审查收集术后住院时间、出院目的地和出院处置的数据。使用曼-惠特尼U检验来检验住院时间数据的差异，使用卡方检验来检验出院处置和出院目的地的差异。在6天和7天物理治疗覆盖的髋关节或膝关节置换术组之间，术后住院时间、出院目的地和出院处置均无显著差异。然而，所应用统计检验的效能较低。本研究没有提供证据表明每周7天的物理治疗会使接受髋关节或膝关节置换术的患者术后住院时间缩短、出院目的地不同或出院处置不同。
