Effectiveness of Fixed PC Interval Using SMS for Afternoon Colonoscopy

Effectiveness of Fixed Preparation-to-Colonoscopy Interval Using Short Message Service (SMS) for Afternoon Colonoscopy: a Randomized Control Study

The purpose of this study is to evaluate the effectiveness of SMS (short message service of mobile phone) reminder to fix PC interval for bowel preparation in afternoon colonoscopy.

Study Overview

• Status: Completed
• Conditions: Effectiveness of SMS to Fix PC Interval
• Intervention / Treatment: Drug: polyethylene glycol (PEG); Behavioral: Short message service of mobile phone (SMS)

Detailed Description

Bowel preparation quality for colonoscopy is influenced by several factors and preparation-to-colonoscopy (PC) interval is one of the important factors. The bowel preparation with split-dose PEG (polyethylene glycol) is an obviously uncomfortable process, it is usually difficult to ingest PEG in time. Therefore, the investigators conducted a prospective randomized control study to evaluate the effectiveness of fixed PC interval for satisfactory bowel preparation in the afternoon colonoscopy using mobile phone short message service (SMS), which reported that it could increase patient's compliance in other practical era

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: No-SMS group; In No-SMS group took 1st 2L of PEG solution at 6-8 PM on the day before colonoscopy and started drinking the 2nd 2L PEG at about 6hours before the day of the colonoscopy without SMS.	Drug: polyethylene glycol (PEG); No-SMS group took 1st 2L of PEG solution at 6-8 PM on the day before colonoscopy and started drinking the 2nd 2L PEG at about 6hours before the day of the colonoscopy. SMS group took 1st 2L PEG as same manner of No-SMS group and then started drinking the 2nd 2L PEG at about 6hours before the day of the colonoscopy after receiving scheduled SMS; Other Names: Colyte
Experimental: SMS group; Patients in SMS group took 1st 2L PEG as same manner of No-SMS group and then started drinking the 2nd 2L PEG at about 6hours before the day of the colonoscopy after receiving scheduled short message service(SMS)	Drug: polyethylene glycol (PEG); No-SMS group took 1st 2L of PEG solution at 6-8 PM on the day before colonoscopy and started drinking the 2nd 2L PEG at about 6hours before the day of the colonoscopy.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
the Ottawa bowel preparation scale	This scale assesses cleanliness and fluid volume respectively and presents the total score as sum of these two values. Cleanliness was assessed for the right colon (cecum, ascending colon), midcolon (transverse, descending colon), and the rectosigmoid colon; each colon section was individually rated from 0 to 4 (0 = no liquid, 1 = minimal liquid, no suction required, 2 = suction required to see mucosa, 3 = wash and suction required, 4 = solid stool, not washable). Fluid quantity was rated from 0 to 2 for the entire colon (0 = minimal, 1 = moderate, 2 = large). The Ottawa Scale scores range from 0 (perfect) to 14 (solid stool in each colon segment and large amount of fluid).	at the end of time of the colonoscopic examination (about 30 minutes-1hour)
