Study summary

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.

Read the 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

Study arms

  • 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)

  • 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)

    Behavioral: Short message service of mobile phone (SMS) · Drug: polyethylene glycol (PEG)

Interventions

  • BehavioralShort message service of mobile phone (SMS)

    In SMS group, patients took 1st dose polyethylene glycol (PEG) 2L at 6-8pm the day before colonoscopy and then start to take 2nd dose PEG 2L after receiving Short message service of mobile phone (SMS) 6hours before afternoon colonoscopy.

  • Drugpolyethylene 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

What researchers measure

Primary outcomes

  1. 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).

    Time frame: at the end of time of the colonoscopic examination (about 30 minutes-1hour)
