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.

Interventions

BEHAVIORALProvider Voice

A phone call with the pre-recorded doctor's voice will be made to their patients who have been pre-screened for obesity before the patient's appointments prompting the patients to ask about physical activity, nutrition, and weight loss.

BEHAVIORALGeneric Voice

A phone call with a pre-recorded neutral voice will be made to the doctor's patients who have been prescreened for obesity before their patient's appointments. The call will prompt them to ask ask their doctor about physical activity, nutrition, and weight loss.
