The Chief of the GI Department wanted to know what the average age is for patients coming in for a first time colonoscopy. The report showed that the average age was 55. Since the recommended age for first colonoscopy is 50, he decides to initiate a campaign where each month, patients who are turning 50 will receive a message letting them know that it is recommended that they schedule a colonoscopy, including the reasons for and benefits of this test. After six months, he will request another report on the average age of first time colonoscopy to see if his reminder system has improved the age of patients scheduling.
