Trial Outcomes & Findings for Improving Comprehensive Cancer Screening Among Vulnerable Patients Using Patient Navigation (NCT NCT02553538)

NCT ID: NCT02553538

Last Updated: 2018-03-26

Results Overview

The primary outcome was the overall cancer screening test completion rate over the follow-up period for each eligible patient, with all eligible cancers combined in intention to treat analyses. For example, a patient who was eligible for a total of 3 screening tests at a given time could have a completion rate of 0% (none of the 3 tests completed) 33%, 67%, or 100% (all 3 tests completed). By assessing each patient's completion rate over the 8-month follow-up period, the average completion rate over time was estimated from the area under the curve. We also calculated the completion rate for each individual cancer as the percentage of time screening was up to date among eligible patients during follow-up.

Measure
Patient Navigation Intervention
Patients randomized to the intervention arm were transferred to a navigator roster within the TopCare application for the 8-month study period. Navigators utilized TopCare to track these patients, reach out to them in their own language, and provide intense outreach to help them complete cancer screening.
Standard of Care - No Intervention
Patients randomized to the control arm received usual care within TopCare, which meant that clinicians and staff could elect to send the patient a reminder letter about their overdue cancer screening exams, reach out to schedule overdue exams, or document appropriate reasons for deferral or exclusion.

PRIMARY outcome

Timeframe: 8 Months

The primary outcome was the average cancer screening test completion rate over the follow-up period for each eligible patient, with all eligible cancers combined in as treated analyses - excluding patients who either left the network or died during follow-up. The cancer screening test completion rate for each subject was calculated daily, then averaged across the 8-month study period. On any given day, the screening test completion rate was calculated as the number of tests completed divided by the number of eligible tests.
