Post-surgical physical activity enhancing program for elderly patients after hip fracture: a randomized controlled trial

Abstract

Abstract Background: Hip fracture seriously influences an elderly person’s life and mobility, independent living, and causes earlier mortality. Although surgery is generally successful, many of the elderly suffer from decreased physical ability after surgery for hip fracture. Objectives: To determine the effects of a physical activity enhancing program (PEP) on the level of physical activity of elderly patients after surgical treatment of hip fracture. Methods: A randomized controlled trial of 46 elderly patients was conducted at King Chulalongkorn Memorial Hospital from January 2012 to February 2013 to evaluate the effectiveness of the Resnick self-efficacy model (2009) compared with standard care in improving physical activity. The participants were enrolled on a criteria basis and were block randomized into two groups. The intervention group attended four phases of physical training and efficacy based intervention comprising assessment, preparation, practicing, and evaluation phases with face-to-face contact and five telephone calls during seven weeks post-surgery. Results: Six weeks after discharge, the physical activity of the intervention group increased by significantly more than the control group (F1,43 = 9.63, P < 0.01), with an effect size of 0.18 after controlling for preoperative physical activity. The ratio of the effect on physical activity induced by the PEP was higher than that induced by usual care (65.2% vs. 47.8%). Conclusion: PEP is effective at improving physical activity. Efforts to follow up for longer periods and with studies using larger populations are recommended.
