Am J Public Health. 2017 Oct;107(10):1660-1667. [Pubmed Abstract]

Kangovi S, Mitra N, Grande D, Huo H, Smith RA, Long JA

Objectives
To determine whether a community health worker (CHW) intervention improved outcomes in a low-income population with multiple chronic conditions.

Methods
We conducted a single-blind, randomized clinical trial in Philadelphia, Pennsylvania (2013-2014). Participants (n = 302) were high-poverty neighborhood residents, uninsured or publicly insured, and diagnosed with 2 or more chronic diseases (diabetes, obesity, tobacco dependence, hypertension). All patients set a disease-management goal. Patients randomly assigned to CHWs also received 6 months of support tailored to their goals and preferences.

Results
Support from CHWs (vs goal-setting alone) led to improvements in several chronic diseases (changes in glycosylated hemoglobin: -0.4 vs 0.0; body mass index: -0.3 vs -0.1; cigarettes per day: -5.5 vs -1.3; systolic blood pressure: -1.8 vs…

Cardiovascular risk outcome and program evaluation of a cluster RCT of a community-based, lay peer led program for people with diabetes

Cardiovascular risk outcome and program evaluation of a cluster randomised controlled trial of a community-based, lay peer led program for people with diabetes
Riddell MA, Dunbar JA, Absetz P, Wolfe R, Li H, Brand M, Aziz Z, Oldenburg B; Australasian Peers for Progress Diabetes Project Investigators

Background
The 2013 Global Burden of Disease Study demonstrated the increasing burden of diabetes and the challenge it poses to the health systems of all countries. The chronic and complex nature of diabetes requires active self-management by patients in addition to clinical management in order to achieve optimal glycaemic control and appropriate use of available clinical services. This study is an evaluation of a “real world” peer support program aimed at improving the control and management of type 2 diabetes (T2DM) in Australia.

Methods
The trial used a randomised cluster design with a peer support intervention and…

How to Achieve Better Effect of Peer Support Among Adults w/Type 2 Diabetes: A Meta-Analysis of RCTs

Patient Educ Couns. 2016 Feb;99(2):186-97. [Pubmed Abstract]

How to achieve better effect of peer support among adults with type 2 diabetes: A meta-analysis of randomized clinical trials.
Zhang X, Yang S, Sun K, Fisher EB, Sun X

Objectives
To study the effects of peer support on glycemic control and examine effects of different providers and types of support, intervention duration and effect duration.

Methods
A meta-analysis of randomized control trials (RCTs) of peer support intervention for patients with type 2 diabetes (T2DM) from beginning to November 3rd, 2014.

Results
Twenty RCTs (n = 4494) were included. In general, peer support intervention (I2 = 49.5%) had significantly positive effect on glycemic control of T2DM with pooled effect on HbA1c of −0.16%, 95% CI −0.25 to −0.007% (−1.7 mmol/mol, P < 0.001). Peer-partner-intervention and Community-health-worker-intervention had much better results of glycemic control. Home-visit-intervention and…
