| Objective To investigate the application value of sports bracelet in bowel preparation for elderly patients undergoing colonoscopy. Methods A series of 120 elderly outpatient (≥ 60 years) who underwent colonoscopy were prospectively randomized into the experimental group and the control group according to the random digital table method, with 60 cases in each group. The two groups were given the same diet instruction and a 3-L split-dose polyethylene glycol (PEG) for bowel preparation. The patients took 1.5 L PEG (250 mL per 10~15 min) at night before colonoscopy, and then took the rest 1.5 L for the same way at 4~6 h before colonoscopy. Proper walking was encouraged during the period of taking PEG. The experimental group was required to walk more than 200 steps after every drinking of 250 mL. If conditions permitted, they would be encouraged to walk again. The control group, according to the opinions of the current bowel preparation guidelines, did not make specific steps, but encouraged proper walking. The two groups wore sports bracelet to monitor the number of walking steps during the period of taking PEG. The tolerance for PEG taking was observed during the bowel preparation. The bowel cleaning quality was assessed using the Boston bowel preparation scale (BBPS) during colonoscopy. Results In experimental group, the number of walking steps, BBPS score and the excellent rate of bowel preparation (91.7% vs. 76.7%) were higher than those in control group (P<0.05). The adverse reaction of nausea, vomiting, abdominal distension, and abdominal pain were significantly lower than those of control group (P<0.05). Pearson correlation analysis showed that there was a significant positive correlation between BBPS score and walking steps during the period of taking PEG (r=0.547, P<0.05). Conclusion Monitoring and quantifying the walking steps during taking bowel cleansing agents using sports bracelet before colonoscopy for the elderly, can quantify walking exercise and improve the quality of bowel preparation. |
