Trial Information

Using Precision Performance Measurement To Conduct Focused Quality Improvement. Sub-Study 1.

We designed an intervention to focus on patients who have received and accepted a referral
for colonoscopy, yet have exhibited some barriers to screening as demonstrated by a lack of
screening completion. We conducted a randomized controlled trial to assess the effects of a
multicomponent intervention (patient reminder, print and multimedia materials) on colorectal
screening completion among this target population.

Inclusion Criteria:

- Patient's physician has ordered a preventive screening test

- Patient has not completed this test in 3 months

- Patient of Northwestern Medical Faculty Foundation General Internal Medicine Clinic.

Exclusion Criteria:

- Patient has been given a more recent order for the same screening test.

- Patient has significant life stress as noted in the Electronic Health Record (EHR)

Type of Study:


Study Design:

Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject), Primary Purpose: Health Services Research

Outcome Measure:

Colorectal Cancer Screening Completion.

Outcome Description:

We reviewed electronic health records of participants 3 months post randomization to ascertain outcome. We looked for one or both of the following (1) note in free text MD note documenting receipt of one form of colorectal cancer (CRC) screening during study period (2)lab results from fecal occult blood test, sigmoidoscopy, or colonoscopy. Participants were categorized as completing CRC screening if there was a lab result or physician note located in chart during study period. If no note or lab result was found in chart, then the participant was categorized as not completing CRC screening.

Outcome Time Frame:

3 months post randomization
