Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="den12467-sec-0001" sec-type="section"> <title>Background and Aim</title> <p>Getting ready for a colonoscopy is difficult and involves many steps. Information given to patients is very important for adherence to treatment. We created a novel smart phone application (SPA) aimed to increase bowel preparation quality and patient satisfaction.</p> </sec> <sec id="den12467-sec-0002" sec-type="section"> <title>Methods</title> <p>We carried out a prospective, endoscopist‐blinded, randomized, controlled trial. We enrolled 260 outpatient (58% female, age range 21–75 years) owners of a smartphone. Patients were allocated to two different protocols: instructions provided by SPA (SPA group; <italic>n</italic> = 108) or written instructions with visual aids (control group; <italic>n</italic> = 152). All procedures were carried out in the afternoon and patients received the same purgative regimen (2 L polyethylene glycol (PEG) solution plus ascorbic acid), in a full‐dose same‐day regimen. The study was designed to detect an improvement in quality of bowel preparation using the Harefield Cleansing Scale (HCS) scale. Effect of protocol on patient satisfaction was assessed with a specific questionnaire at the time of colonoscopy.</p> </sec> <sec id="den12467-sec-0003" sec-type="section"> <title>Results</title> <p>Proportion of patients who obtained successful bowel preparation for colonoscopy (HCS A or B) was significantly higher in the SPA group than in the control group (100% <italic>vs</italic> 96.1%, respectively; <italic>P</italic> = 0.037). Mean global HCS scores were similar in both groups. Patient‐reported tolerability and overall experience with the prescribed bowel preparation were significantly higher for the SPA group than for the control group.</p> </sec> <sec id="den12467-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Successful cleansing and patient acceptability with the use of SPA were superior to written instructions in outpatients submitted for colonoscopy using 2 L PEG solution plus ascorbic acid.</p> </sec> </abstract>
