Comparison Of Different Interventions In Patients With Previous Poor Bowel Preparation

Objective: To compare the telephone re-education and oral administration of the compound polyethylene glycol electrolyte solution in patients with poor bowel preparation.Methods: Information was collected from 234 patients who underwent colonoscopy at the Third Affiliated Hospital of Anhui Medical University from September 2017 to June 2018 and were unsatisfied with previous bowel preparations.The 234 patients were randomly assigned into 3 groups and 229 patients finally completed the examination.All patients received bowel preparation with 3L compound polyethylene glycol electrolyte solution.Intervention group 1(76 cases)received telephone re-education in the morning on the day of bowel preparation,intervention group 2(78 cases)were given split-dose oral drug regimen on the same day,and control group(75 cases)was given continuous oral drug regimen.The bowel preparation score was counted during the colonoscopy using the Boston Rating Scale.The self-designed questionnaire was used to collect adverse reactions during the patient's medication and to determine which bowel preparations were preferred.Results The mean values of Boston scores in the right colon of intervention group 1,intervention group 2 and control group were 2.11±0.56,2.26±0.61,and 2.03±0.59,respectively,and the differences was statistically significant among the three groups(P<0.05),with the score in intervention group 2 the highest(P<0.05).The incidence of adverse reactions during medication of intervention group 1,intervention group 2,and the control group was 35.5%.17.9%,and 32.0%,and the differences were statistically significant(P<0.05),with the incidence the lowest in intervention group 2(P<0.05).The detection rate of adenomas in intervention group 1,intervention group 2,and the control group was 14.5%,20.5%,and 9.3%,respectively,and the differences were not statistically significant among the three groups(P>0.05).The proportions of patients wanted to change bowel preparation regimen in intervention group 1,intervention group 2,control group were 36.8%,33.3%,and 40.0%,respectively,and the differences were not statistically significant among the three groups(P>0.05).Conclusion Patients with poor bowel preparations may be treated with split-dose compound polyethylene glycol electrolyte solution to improve intestinal cleanliness and reduce adverse reactions.It is not recommended to strengthen education.However,there is still a need to further explore a more personalized,simple,and time-saving bowel preparation program to improve the cleanliness of the entire intestine.
