- Registration Number
- NCT02553538
- Lead Sponsor
- Massachusetts General Hospital
- Brief Summary
Patient navigation (PN) has been shown to improve rates of cancer screening in vulnerable populations. Most cancer PN programs are located in community health centers and focus on a single cancer. The investigators will evaluate the impact of PN program on breast, cervical, and/or colorectal cancer screening in vulnerable patients receiving care in a large, academic, primary care network using a population-based IT system.
- Detailed Description
It is important to note that the TopCare system is currently the standard of care in the MGPC-PBRN. As such, this proposal does not involve evaluating the TopCare system or the patients and providers using it. Rather, the study evaluates the part of the TopCare system that involves the automated identification and referral to PN of patients at increased risk of screening non-adherence. All eligible patients overdue for cancer screening tests will receive usual care that includes a reminder letter and referral to a scheduling delegate for follow-up. Since the TopCare system represents usual care for patients with the MGH primary care network, no patient contact will occur solely for research purposes. The study will involve randomly assigning participants overdue for screening and identified as high risk for not completing screening to early or delayed PN. The investigators believe this random assignment is ethical because PN is an extremely limited resource, and all patients in the investigators network identified as high risk for not completing screening could not be contacted by the investigators navigators in a short period of time. Thus, the investigators will randomly assign access to PN during the study period, and then allow all participants to be navigated after the study period is over. As a result, all overdue, high risk patients will be referred for PN, but the timing of the referral will be randomly assigned. In this study, the investigators objectives are to improve the algorithm to automatically identify patients who are more likely to benefit from PN (Specific Aim 1), and to evaluate the clinical impact of PN in a randomized controlled trial within the MGPC-PBRN (Specific Aim 2). Investigators will also survey all patients identified by the TopCare algorithm to assess their overall satisfaction with healthcare to determine whether PN impacts satisfaction with healthcare (Specific Aim 3).
Revising and improving the current 'high risk' algorithm to automatically identify patients who may be helped by PN in Specific Aim 1 will help us to most effectively utilize limited PN resources. The current algorithm utilizes information about patient age, number of overdue tests, primary language, and no-show visit history. The investigators will investigate adding patient registration information about insurance and education status to better identify patients at high risk for not completing screening.
In Specific Aim 2, investigators will randomize eligible patients from the MGPC-PBRN primary care practices to either Arm 1 - TopCare with PN: Patients identified as at high risk for not completing screening by the automated algorithm will be assigned to a PN list for contact to help schedule and complete screening (breast, cervical, and colon), or Arm 2 - TopCare without PN: These patients will benefit from the standard features of the TopCare system, including automated identification of overdue patients, patient reminder letters, and referral to a scheduling delegate. All high risk patients in this arm will be eligible for PN after the study period is over.

Group Intervention Description Patient Navigation Intervention Patient Navigation Participants 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 participants, reach out to them in their own language, and provide intense outreach to help them complete cancer screening.
- Primary Outcome Measures
Name Time Method Percentage of Cancer Screening Tests Completed - Intention to Treat 8 months 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.
Percentage of Cancer Screening Tests Completed - As Treated 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.
- Secondary Outcome Measures
Name Time Method Percentage of Patients Completing Any Cancer Screening Test (Intention to Treat) 8 Months The percentage of patients completing any cancer screening during follow-up among those who were eligible and overdue for at least one cancer screening at baseline in intention to treat analyses, as the percentage of patients completing each type of cancer screening among those who were eligible and overdue at baseline in intention to treat analyses.
Percentage of Patients Completing Any Cancer Screening Test (As Treated) 8 Months The percentage of patients completing any cancer screening during follow-up among those who were eligible and overdue for at least one cancer screening at baseline in intention to treat analyses, as the percentage of patients completing each type of cancer screening among those who were eligible and overdue at baseline, removing patients who left our primary care network or who died during follow-up from both intervention and control arms, and also removed patients the navigators were not able to contact from the intervention arm.
