“…The second RCT compared patients undergoing abdominal hysterectomy who received either usual care protocol or an efficacyenhancing teaching protocol preoperatively. 6 Participants in the intervention group ambulated longer than participants in the usual care group (330 vs 156 seconds, P ¼ .043). However, there were no significant differences between the groups in preoperative self-efficacy scale score, State Anxiety Inventory score, pain scores on the visual analog scale, vital capacity, preventable complications (atelectasis, pneumonia, paralytic ileus, and deep vein thrombosis), length of stay, and health status questionnaire scores at 6 months postoperatively.…”
