Patients are stratified according to age (≤ 65 years of age vs \\> 65 years of age), gender, time elapsed since last colonoscopy, and primary care physician's (PCP) membership in Harvard Vanguard Medical Associates (yes vs no). Patients are randomized to 1 of 2 arms.\n\n* Arm I: PCPs are mailed response forms (regarding the disposition of their eligible patients \\[e.g. patient letter mailed, patient called, scheduled for colonoscopy, colonoscopy completed elsewhere, patient refused procedure, clinical contraindication, patient deceased\\]) and letters reminding them that their patients are due for a follow-up colonoscopy. PCPs who do not return response forms within 4 weeks are sent a second set of reminders and patient letters.\n* Arm II: Six months after the beginning of the study, PCPs are mailed response forms and patient letters once. A second set of reminders and patient letters are not sent.\n\nPROJECTED ACCRUAL: A total of 800 patients will be accrued for this study."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '21 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "DISEASE CHARACTERISTICS:\n\n* Prior diagnosis of adenomatous polyp\n* Underwent prior colonoscopy with polypectomy at Brigham and Women's Hospital\n\n * Due for repeat colonoscopy according to current national guidelines of the American Gastroenterology Association (no colonoscopy within the past 5 years)\n\nPATIENT CHARACTERISTICS:\n\n* Not specified\n\nPRIOR CONCURRENT THERAPY:\n\n* See Disease Characteristics"}, 'identificationModule': {'nctId': 'NCT00397969', 'briefTitle': 'Improving the Frequency of Colonoscopy in Patients With a Previous Colorectal Polyp', 'organization': {'class': 'NIH', 'fullName': 'National Cancer Institute (NCI)'}, 'officialTitle': 'Improving Surveillance for Colorectal Polyps', 'orgStudyIdInfo': {'id': 'CDR0000492752'}, 'secondaryIdInfos': [{'id': 'HMS-M11837-103'}, {'id': 'BWH-2005-P-000371/3'}, {'id': 'HPHC-1705'}]}, 'armsInterventionsModule': {'interventions': [{'name': 'counseling intervention', 'type': 'OTHER'}, {'name': 'screening colonoscopy', 'type': 'PROCEDURE'}]}, 'contactsLocationsModule': {'locations': [{'zip': '02115', 'city': 'Boston', 'state': 'Massachusetts', 'country': 'United States', 'facility': "Dana-Farber/Brigham and Women's Cancer Center", 'geoPoint': {'lat': 42.35843, 'lon': -71.05977}}, {'zip': '02115', 'city': 'Boston', 'state': 'Massachusetts', 'country': 'United States', 'facility': 'Harvard Medical School', 'geoPoint': {'lat': 42.35843, 'lon': -71.05977}}], 'overallOfficials': [{'name': 'John Ayanian, MD, MPP', 'role': 'STUDY_CHAIR', 'affiliation': 'Harvard Medical School (HMS and HSDM)'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Harvard Medical School (HMS and HSDM)', 'class': 'OTHER'}, 'collaborators': [{'name': 'National Cancer Institute (NCI)', 'class': 'NIH'}]}}}
