Trial of Provider-to-Patient Interactive Voice Response (IVR) Calls to Improve Weight Management in Community Health Centers (CHCs)

Study Overview
=================
Brief Summary
-----------------
This study will test the effect of provider to patient interactive voice response (IVR) calls in local Community Health Centers within a weight management program.

Detailed Description
-----------------
We will randomize providers to three groups. Patients whose provider has been randomized to usual care will not receive IVR calls but do have available a guideline-level weight management service in TCL. Groups one and two will receive pre-visit and post-referral calls. The pre-visit call will invite patients who want to discuss weight at their upcoming visit with their provider to remember to do so. The post-referral call will remind patients that they have received a referral and encourage them to schedule a visit with the community based weight intervention program. Patients whose provider has been randomized to group 1 will receive IVR calls using their scheduled and referring provider's voice. Group 2 will receive IVR calls using a standard IVR voice.
