Trial of Provider-to-Patient Interactive Voice Response (IVR) Calls to Improve Weight Management in Community Health Centers (CHCs)
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.
|Study Design:||Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Factorial Assignment
Masking: Open Label

|Official Title:||An RCT of Provider-to-Patient IVR Calls to Improve Weight Management in CHCs|
- Weight loss refer by provider [ Time Frame: 6 months ] [ Designated as safety issue: No ]
- attendance at program, weight loss [ Time Frame: 6 months ] [ Designated as safety issue: No ]
|Study Start Date:||June 2009|
|Study Completion Date:||January 2012|
|Primary Completion Date:||December 2010 (Final data collection date for primary outcome measure)|
Experimental: Treatment Group 1
Patients will receive a pre-visit, post-referral and post-contact phone call using providers voice
Behavioral: Provider 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.
Experimental: Treatment Group 2
Patients will receive a previsit, post-referral and post-contact call using a generic voice
Behavioral: Generic 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.
No Intervention: Treatment Group 3
Patients will be provided usual care with no additional phone calls.
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.
