Trial Outcomes & Findings for Evidence-Based Colorectal Cancer Screening for the Uninsured (NCT NCT01946282)
NCT ID: NCT01946282
Last Updated: 2020-03-19
Results Overview
Primary outcome was analyzed using an intent-to-screen approach where a 2-sided P-value \<0.05 was considered statistically significant. Patients were randomly assigned to one of 3 groups: outreach only, outreach + $5 incentive upon FIT return, and outreach + $10 incentive upon FIT return. For analysis, incentive groups were combined and compared to outreach alone.

Participant Flow
18,700 age-eligible patients with qualifying outpatient clinic visits were identified for invitation. 10,135 patients were excluded from participation due to the following: primary language not English or Spanish, missing contact information, incarceration, screen up-to-date, and prior history of colorectal cancer or inflammatory bowel disease.

PRIMARY outcome
Timeframe: Each year for three yearsPopulation: If FIT is positive, patients are routed to appropriate treatment. If FIT is negative, patients mailed invitations in the following year.
Primary outcome was analyzed using an intent-to-screen approach where a 2-sided P-value \<0.05 was considered statistically significant. Patients were randomly assigned to one of 3 groups: outreach only, outreach + $5 incentive upon FIT return, and outreach + $10 incentive upon FIT return. For analysis, incentive groups were combined and compared to outreach alone.
Outcome measures
| Measure |
Standard Invite
n=6565 Participants
Fecal Immunochemical Test (FIT) kits and an invitation letter to complete colorectal cancer screening are mailed to the homes of study eligible patients. A postage paid return mailer is included. Automated and "live" phone call reminders are made at the time of invitation and within one week of invitation. Up to two "live" phone call reminders are attempted 2 to 3 weeks post invitation.

Incentive Invite
n=2000 Participants
The denominator population for evaluating baseline and end of Year 3 screening rates will consist of patients meeting the following criteria: 1) Age 50-64, 2) Uninsured, but participants in JPS's medical assistance program for the uninsured, 3) One or more visits to a JPS primary care clinic within a year, 4) Address and phone number on file, 5) No history of CRC or colon resection, 6) Not incarcerated
|
Outreach Alone
The outreach included: (i) a mailed invitation to complete and return the FIT in English and Spanish; (ii) a 1-sample Polymedco OC Sensor FIT test; (iii) 2 automated telephone reminders in English and Spanish at the time invitations were mailed and 1 week later, encouraging test completion; and (iv) up to 2 live telephone reminders within 3 weeks of the invitation mailing, if the FIT was not returned or if the patient had not been reached during earlier attempts.

SECONDARY outcome
Timeframe: Each year for three yearsPopulation: Patients were re-invited after participation in previous year and had a negative FIT result.
Patients were randomly assigned to one of 3 groups: outreach only, outreach + $5 incentive upon FIT return, and outreach + $10 incentive upon FIT return. In year 4, use of financial incentives were discontinued and all patients with a normal result in year 3 were invited to complete a FIT using outreach only, regardless of their original intervention group.
