Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The project aims to evaluate four different versions and modalities of interventions encouraging mammogram screening among all eligible women due or overdue for screening. The evaluation will compare among the following forms of outreach to help determine whether (a) live calls are more effective at increasing mammogram screening than other forms of outreach and (b) each form of outreach is more effective than no outreach: (1) a postcard, (2) a letter, (3) an auto-dialer phone message, and (4) a live call from a care gaps team. The interventions will be rolled out over many months, allowing for comparisons of effectiveness against those who have not yet been contacted.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Each intervention will be rolled out to only a subset of the total population each month, such that all patients will receive one of the interventions over the course of 7 months. Active arms will be compared contemporaneously against a passive control group consisting of active arm participants for whom the intervention has not yet begun, as well as a random subset of participants who are excluded before the future intervention begins.

Primary Study Purpose

SCREENING

NONE
