The changes in clinical practice following a randomised controlled trial of early discharge for inguinal hernia and varicose veins are reviewed. A significant reduction in mean length of stay was recorded in the study area between 1970 (the year before the start of the study) and 1975 (two complete years after the study). This change was not found in two adjacent health districts.
回顾了一项关于腹股沟疝和静脉曲张早期出院的随机对照试验后临床实践的变化。在研究区域,1970年(研究开始前一年)至1975年(研究结束后的完整两年)期间,平均住院时间显著缩短。在相邻的两个卫生区未发现这种变化。
