Colonoscopy is a widely used procedure to visualize the mucosa of the entire large intestine and distal terminal ileum in order to diagnose and treat colon disorders. Based on 2010 data, over 3.3 million outpatient colonoscopies were performed annually in the United States, with screening and polyp surveillance accounting for half of indications. Optimal effectiveness of colonoscopy depends on patient acceptance of the procedure, which depends mostly on acceptance of the bowel preparation. Colonoscopy Prep Reminder helps to relieve that problem. The gastroenterologists’ office will be able to send out scheduled text messages the day prior to the patients colonoscopy, walking them through the steps of the colonoscopy preparation. Simply enter the date of the colonoscopy and the patients text-capable phone number into the app and automatically the app will send out 5 messages on the day prior to the colonoscopy to remind the patient of important objectives to improve their compliance with the bowel prep. Disclaimer: Please make sure your patient is agreeable to receive these messages according to HIPPA compliance. This app was designed by Dr. Nihar Shah (MD, FACP)
