Comparing Interventions to Increase Colorectal Cancer Screening

16 augustus 2021 bijgewerkt door: Susan Rawl, Indiana University

Comparing Interventions to Increase Colorectal Cancer Screening in Low-Income and Minority Patients

The purpose of this study is to test different approaches to help people understand the purpose of colorectal cancer (CRC) screening, two screening test options available, and the barriers to screening so they can make informed decisions about CRC screening. Participants will be randomly assigned to one of three groups: (1) one group will receive a tailored digital video disc (DVD) in the mail; (2) another group will receive the mailed DVD plus telephone calls from a patient navigator; and (3) the third group will receive the care normally provided by the healthcare system's endoscopy department.

The investigators hypothesize the following: (1) participants who receive the tailored DVD plus the patient navigation intervention will have higher rates of CRC screening with the fecal immunochemical test (FIT), colonoscopy, or either screening test compared to those who receive the tailored DVD alone; (2) participants who receive either intervention (DVD only or DVD plus patient navigation) will have higher rates of CRC screening with FIT, colonoscopy, or either screening test than those who receive usual care; and (3) participants who receive either intervention who complete colonoscopy will have better quality of bowel preparation, less anxiety about the procedure, and greater satisfaction with the colonoscopy experience than those who receive usual care.

Gedetailleerde beschrijving

Colorectal cancer (CRC) often can be prevented through regular screening and although multiple screening tests are available, colonoscopy is often the only screening test offered to patients. Unfortunately, up to half of people in some hospitals who receive a recommendation and are scheduled for colonoscopy do not complete the test. Reasons for not completing colonoscopy include lack of awareness of the need for, and benefits of, screening, fear of pain, fear of finding cancer, unpleasantness of the bowel preparation, cost, transportation issues, and the unwillingness to undergo an invasive test in the absence of symptoms. The process of bowel cleansing is one of the most challenging aspects of having a colonoscopy. Interventions that improve patients' knowledge about CRC screening, including test options other than colonoscopy, enhance access, improve skills needed to complete CRC screening, and reduce barriers will lead to greater numbers of people being screened. Patient navigation and computer tailored interventions have been shown to be effective approaches to increase CRC and other cancer screening but there is no evidence of their comparative effectiveness. The purpose of this study is to compare two health system-based interventions, with one another and with usual care, to increase completion rates among a diverse sample of patients. The investigators will enroll an ethnically diverse group of 450 men and women aged 50-75,or aged 45-75 if African American, who are at average risk for CRC and were referred and scheduled for colonoscopy at one endoscopy department but canceled or did not attend their scheduled appointment. Participants will be randomized to receive: (1) a mailed tailored digital video disc (DVD) alone; 2) the mailed tailored DVD plus a telephone-based Patient Navigator; or 3) usual care. Data will be collected at baseline, at 6 months and at 9 months post-baseline. Interviews to assess receipt, viewing, and satisfaction with the tailored DVD will be conducted 2 weeks after mailing. Satisfaction with the patient navigator will be assessed at 6 months. Multivariable logistic regression analyses will be used to test the interventions' effects on CRC screening test completion and, for those who complete colonoscopy, quality of bowel preparation. The investigators will also examine whether these interventions change knowledge about CRC and screening as well as health beliefs (perceived risk, perceived benefits, barriers, and self-efficacy) about screening. From this study, the investigators will learn how effective these two standardized, easy to disseminate health system-based interventions are compared to each other and to usual care. If the interventions are found to be equally effective, or differentially effective for different subgroups of patients, healthcare systems may consider implementing one or both of these interventions in their settings.

Interventie / Behandeling
Actieve vergelijker: Tailored DVD
Tailored digital video disc (DVD)
A 20 minute tailored DVD titled "Approaches to Colon Testing" is viewed by participants. It is designed to encourage CRC screening uptake by colonoscopy or FIT by increasing the participant's CRC knowledge and beliefs about the benefits of screening, reducing barriers to screening, and increasing self-efficacy for screening by demonstrating how these tests are performed.
Actieve vergelijker: Tailored DVD + Patient Navigation
Tailored digital video disc (DVD) plus Patient Navigation by a population health nurse in the healthcare system
A 20 minute tailored DVD titled "Approaches to Colon Testing" is viewed by participants. It is designed to encourage CRC screening uptake by colonoscopy or FIT by increasing the participant's CRC knowledge and beliefs about the benefits of screening, reducing barriers to screening, and increasing self-efficacy for screening by demonstrating how these tests are performed.
Participants talk by telephone with a Patient Navigator who is a trained nurse. The Patient Navigator determines if participants viewed the tailored DVD and answers any questions about the content. The Patient Navigator then provides telephone counseling on CRC and screening tests to: (1) increase knowledge, perceived benefits, and self-efficacy; (2) reduce barriers; (3) enhance access; and (4) provide social support.
Geen tussenkomst: Usual Care
Care normally provided by a nurse in the endoscopy department of the healthcare system

Bowel Preparation Quality Rating Using Boston Bowel Preparation Scale
Tijdsspanne: 12 months post-baseline interview
Participants quality of bowel preparation is measured by the endoscopist during their colonoscopy procedure using the Boston Bowel Preparation Scale (BBPS). BBPS scores the total quality on a 10 point scale from 0-9. Higher scores indicate better quality of bowel preparation.
12 months post-baseline interview
Participants With Adequate Quality of Bowel Preparation Per Modified Aronchick Rating Scale
Tijdsspanne: 12 months post-baseline interview
Participants quality of bowel preparation is measured by the endoscopist during their colonoscopy using a modification of the Aronchick rating scale. The Aronchick scale rates quality as 1=excellent, 2=good, 3=fair, or 4=poor. Some endoscopists choose to grade quality more generally as adequate vs. inadequate. To accommodate this variation, bowel preparation ratings have been dichotomized into adequate (excellent, good, fair, or adequate ratings) vs. inadequate (poor or inadequate ratings). Adequate is scored as 1 and indicates better quality of bowel preparation than inadequate which is scored as 0.
12 months post-baseline interview
Colonoscopy-Related Procedural Anxiety for Participants Completing a Colonoscopy
Tijdsspanne: 12 months post-baseline interview
Colonoscopy-related procedural anxiety is measured by self-report using the 6-item short form of the State Anxiety Scale of the State-Trait Anxiety Inventory. Each item is scored from 1 to 4 (1=not at all; 4=very much so) with higher scores indicating greater anxiety.
12 months post-baseline interview
Satisfaction With Colonoscopy Experience
Tijdsspanne: 12 months post-baseline interview
Satisfaction with the colonoscopy experience is measured by self-report using a single item developed by the research team. Satisfaction is rated from 1 to 4 where 1=not at all satisfied, 2=a little satisfied, 3=mostly satisfied, and 4=completely satisfied. Scores range from 1 to 4 with higher scores indicating greater satisfaction.

6-9 months post-baseline interview
Change in Knowledge of CRC and Screening
Tijdsspanne: 6 months post-baseline interview
Change from baseline in knowledge of CRC and screening is measured at 6 months by self-report using a 9-item multidimensional scale. Each item is scored as 1=correct or 0=incorrect and summed to yield a scale score. Scores range from 0 to 9 with higher summated scores indicating greater knowledge of CRC and screening tests. The mean of the 9 items is calculated at baseline and 6 months post-baseline. Change from baseline equals the mean at 6 months minus the mean at baseline. Change can range from -9 to 9 with positive values indicating an increase in knowledge.
6 months post-baseline interview
Change in Perceived Risk for CRC
Tijdsspanne: 6 months post-baseline interview
Change from baseline in perceived risk for CRC is measured by self-report at 6 months using a 3-item scale. We ask participants how likely it is that they will get colon cancer sometime during their lifetime, within the next 10 years, and within the next 5 years. Each item is scored from 1 to 4 (1=very unlikely; 4=very likely). Higher scores indicate a higher perceived risk for getting CRC. The mean of the 3 items is calculated at baseline and 6 months. Change in perceived risk equals the mean at 6 months minus the mean at baseline. Change can range from -3 to 3 with positive values indicating an increase in perceived risk for getting CRC.
6 months post-baseline interview
Change in Colonoscopy-Related Procedural Anxiety Regardless of Whether or Not Participants Had a Colonoscopy
Tijdsspanne: 6 months post-baseline interview
Change from baseline in colonoscopy-related procedural anxiety is measured at 6 months by self-report using the 6-item short form of the State Anxiety Scale of the State-Trait Anxiety Inventory. Each item is scored from 1 to 4 (1=not at all; 4=very much so) with higher scores indicating greater anxiety. The mean of the 6 items is calculated at baseline and 6 months post-baseline. Change from baseline is the mean at 6 months minus the mean at baseline. Change can range from -3 to 3 with positive values indicating an increase in anxiety.

Each item is scored from 1 to 4 (1=strongly disagree; 4=strongly agree) and the mean of the 4 items calculated. Higher mean scores indicate greater perceived benefits of screening by colonoscopy. Change in perceived benefits equals the mean at 6 months minus the mean at baseline. Change can range from -3 to 3 with positive values indicating an increase in perceived benefits of screening by colonoscopy.
6 months post-baseline interview
Change in Perceived Barriers to CRC Screening by Colonoscopy
Tijdsspanne: 6 months post-baseline interview
Change from baseline in perceived barriers to CRC screening by colonoscopy is measured at 6 months by self-report using a 16-item scale. Each item is scored from 1 to 4 (1=strongly disagree; 4=strongly agree) and the mean of the 16 items calculated. Higher mean scores indicate greater perceived barriers to screening by colonoscopy. Change in perceived barriers equals the mean at 6 months minus the mean at baseline. Change can range from -3 to 3 with negative values indicating a decrease in perceived barriers to screening by colonoscopy.
6 months post-baseline interview
Change in Perceived Self-Efficacy for CRC Screening by Colonoscopy
Tijdsspanne: 6 months post-baseline interview
Change from baseline in perceived self-efficacy for colonoscopy is measured at 6 months by self-report using an 11-item scale. Each item is scored from 1 to 4 (1=not at all sure; 4=very sure) and the mean of the 11 items calculated. Higher mean scores indicate greater perceived self-efficacy for screening by colonoscopy. Change in perceived self-efficacy equals the mean at 6 months minus the mean at baseline. Change can range from -3 to 3 with positive values indicating an increase in perceived self-efficacy for screening by colonoscopy.
6 months post-baseline interview
Change in Perceived Benefits of CRC Screening by FIT
Tijdsspanne: 6 months post-baseline interview
Change from baseline in perceived benefits of CRC screening by FIT is measured at 6 months by self-report using a 3-item scale.
