Surveillance Colonoscopy in Older Adults: The SurvOlderAdults Study

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

Colorectal cancer is a leading cause of cancer death. Detection and removal of polyps can reduce risk for developing colorectal cancer. After finding and removing precancerous polyps, repeat colonoscopy is routinely recommended. However, it is unclear whether repeat additional colonoscopy further reduces risk for colorectal cancer. For older adults age 75 and older, the lack of this information is especially important, given that the risks of colonoscopy go up with age. This research will evaluate whether older adults with a prior history of precancerous polyps have higher colorectal cancer risks compared to older adults who had a prior normal colonoscopy, and whether, among those with prior precancerous polyps, repeating a colonoscopy after age 75 is associated with reduced cancer risk. The investigators will synthesize these data and gather perspectives from Veterans and clinical stakeholders to make recommendations on whether older adults with a prior history of polyps should continue or defer colonoscopy after age 75.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:75 Years
Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:No
Standard Ages:OLDER_ADULT
Inclusion CriteriaExclusion Criteria
  1. * The study base will consist of any Veteran alive at age 75 between 2005-2019, with exposure to a qualifying colonoscopy in the 10-year period prior to turning age 75
  2. * The investigators will include those with a qualifying colonoscopy associated with a colonoscopy note that can be processed by the previously established natural language processing (NLP) pipelines for extracting colonoscopy data from free-text reports60, 61 (see prior work below)
  3. * The colonoscopy done closest to, but prior to age 75 will be considered as a candidate qualifying colonoscopy
  4. * Date of cohort entry (start of follow up) will be defined as date at which a participant meeting inclusion criteria turned 75
  5. * Date of qualifying colonoscopy prior to age 75 will be defined as the qualifying colonoscopy reference date
  6. * The study base for Aim 2 consists of Veterans ages 75 and alive between 2003-2019 who had a polypectomy prior to turning age 75
  7. * Identification of the study base for Aim 2 will take a distinct approach from Aim 1
  8. * A candidate qualifying colonoscopy event will be defined by presence of a CPT code for colonoscopy associated with a pathology note-based diagnosis of an adenoma within 30 days of the CPT code for colonoscopy
  9. * The colonoscopy event occurring closest to, but prior to age 75 will be selected
  10. * From the study base, all individuals who developed incident or fatal CRC, and a random sample of the entire study base will undergo manual EHR chart review to confirm study eligibility
  11. * To identify candidate incident CRC cases, the investigators will identify all adults with a CRC diagnosis at ages 75, utilizing the Oncology Domain with the same strategy for incident CRC identification as described for Aim 1
  12. * To identify candidate fatal CRC cases, the investigators will identify all adults with a fatal CRC diagnosis at ages 75, using NDI cause-specific mortality data
  13. * To identify candidate members of the subcohort for chart review, a random sample of the study base will be drawn
  14. * This sample may include Veterans with and without subsequent CRC. Rationale for including Veterans with and without subsequent CRC (incident and/or fatal) in the control subcohort is well established
  15. * Specifically, if the investigators were to conduct a cohort study without sampling, then at the start of follow up, the cohort would include people with subsequent CRC
  16. * In a traditional cohort study, every CRC case contributes to the denominator of individuals at risk. Thus, by including in the subcohort Veterans with and without CRC on follow up, the investigators are able to calculate risk based on exposure to surveillance as if the investigators had conducted a cohort study utilizing the entire cohort
  17. * The investigators will use EHR data to generate a list of VASDHS and VAGLA patients who have:
  18. * a) age 75
  19. * b) history of colonoscopy with polypectomy in the past 10 years
  20. * c) been referred for surveillance colonoscopy
  21. * The investigators will randomly select patients, recruiting until the investigators have 12 who completed surveillance colonoscopy and 12 who have not completed surveillance
  22. * The investigators will monitor the sample to assure sex balance consistent with VA demographics for patients who have had colonoscopy (98.2% male and 1.8% females age 75)
  23. * The investigators will also ensure that at least one- third of sampled patients have moderate or severe frailty based on the claims-based VA-FI36, 64 and make efforts to maintain patient racial/ethnic and geographic (i.e. San Diego/Los Angeles areas) diversity
  24. * The investigators will conduct interviews with 20 providers, specifically 10 primary care providers (including 3-4 geriatricians) and 10 gastroenterologists
  25. * The investigators will select providers from a randomly generated list of practicing VA clinicians (5/8th or greater) at VASDHS or VAGLA
  26. * If the investigators experience challenges reaching the target sample size, the investigators will employ snowball sampling by asking participants to name other potentially eligible clinicians
  27. * The investigators anticipate reaching thematic saturation given \> 17 interviews in each group and have made provisions to accommodate up to 6 additional patient and/or provider interviews if new themes continue to arise by the end of the planned interviews
  28. * The investigators will make efforts to achieve geographic balance to ensure provider representation from VASDHS and VAGLA
  29. * The investigators will convene a group of 15-20 multi-level stakeholders for the in-person expert panel in Quarter 1 of Year 4
  30. * The panel will include VA patients and caregivers (not included in Aim 3a):
  31. * VA providers
  32. * VA leadership and policymakers
  33. * health services and clinical researchers
  34. * individuals with non-VA healthcare systems perspectives
  1. * History of CRC prior to age 75
  2. * History of sessile serrated adenoma/polyp/lesion (SSL), traditional serrated adenoma (TSA), or large serrated polyp (LSP, defined as hyperplastic polyp \>10mm) at qualifying colonoscopy
  3. * History of inflammatory bowel disease (IBD) prior to age 75
  4. * Absence of exposure to normal colonoscopy or colonoscopy with polypectomy between ages 65-75
  5. * All candidate CRC cases and members for the subcohort will be included in the analytic sample unless they meet one of the following
