Brief Summary

SOS is a four-arm randomized controlled study of ways to increase screening for colorectal cancer. About 40-50% of the people age 50 and older are not up to date on screening. This is a very important problem because screening both prevents colorectal cancer and decreases colon cancer deaths. We are studying 3 different levels of support to help people get screened and follow-up after positive screening tests. These involve comparing to usual care stepwise increasing in intensity approaches; an automated approach of mailing information and home screening tests, this plus phone assistance by a medical assistant, both of these plus phone counseling and care management. We will also compare nurse assisted follow-up after a positive screening test compared to usual care By doing this study we hope to increase colon cancer screening rates, and also follow-up rates for positive screening tests.

Outcome Measures

Primary Outcomes (2)

  • Short-term adherence to CRC screening

    To compare CRC screening adherence by randomization arm: Any screening during years 1 or 2; (b) Screening coverage during both years 1 and 2.

    From randomization to the end of 2 years

  • Long-term adherence to CRC screening

    To compare the proportion of time participants are adherent to CRC screening long-term (initial randomization to the end of year 9).

    From randomization to the end of 9 years

Secondary Outcomes (2)

  • Short and long-term adherence to CRC screening for those eligible for re-randomization in year 3

    From year 3 to the end of 9 years

  • Impact of SOS interventions on outcomes and CRC-related costs

    From randomization to the end of 9 years

Study Arms (4)

1- Usual Care

NO INTERVENTION

Usual Care (UC) includes an annual birthday letter with information on overdue screening tests including CRC screening.

2 - Automated Mailing

EXPERIMENTAL

Usual care plus automated mailing. Mailing 1 is a pamphlet about screening choices and number to call for colonoscopy. Mailing 2 is a FIT kit if not requesting colonoscopy. Mailing 3 is a Reminder letter.

Behavioral: Automated Mailing

3 - Automated Mailing Plus Assisted

EXPERIMENTAL

Usual care, automated mailing plus, if screening is still not completed, phone assistance by a medical assistant (MA) who asks about patients screening intent, and provides brief assistance to complete this (e.g. sends another fecal test, assists with provider order for a colonoscopy).

Behavioral: Automated Mailing Plus Assisted

4 - Auto Plus Assisted Plus Navigation

EXPERIMENTAL

Usual care, automated mailing, phone assistance by a medical assistant, plus navigation by a registered nurse (RN) if still not screened. Navigators are trained to use motivational interviewing techniques. They assess CRC and procedure risk, facilitate screening choice, address barriers, and provide follow-up until screening is completed.

Behavioral: Auto Plus Assisted Plus Navigation

Interventions

Usual Care plus Automated mailing

2 - Automated Mailing

If not screened after automated mailing, MA assists with screening.

3 - Automated Mailing Plus Assisted

If not screened after automated mailing and assistance by MA, RN begins navigation.

4 - Auto Plus Assisted Plus Navigation
