Northern Manhattan Diabetes Community Outreach Project

The objective of this project is to examine the effectiveness of a community health worker
(CHW) intervention at addressing glycemic control among Latinos with poorly controlled Type
2 diabetes. Our group has worked with a promising model of intervention that utilizes CHW's
based at one of our major community partners. Pilot data from this program has shown
clinically significant prepost test improvements in HgA1C. Using the Chronic Care Model as
an overarching framework, the study design of NOCHOP is a randomized controlled trial of 360
Latinos, mostly of Caribbean descent, aged 3570 years with HgA1C >=8.0. At a minimum,
subjects in the intervention group will receive four home visits, ten group level visits and
monthly phone calls by CHWs based at Alianza. The control groups will receive three separate
mailings of bilingual diabetes health education materials. The primary outcome is glycemic
control at 12month follow up, as measured by HgA1c. The secondary outcomes are changes in
cholesterol and blood pressure (BP). We will also collect exploratory data on potential
mechanisms through which our intervention resulted in hypothesized improvements including
medication adherence, medication Intensification, diet and exercise. If successful, our
project will make an important contribution to ongoing national and local debates about the
sustainability of CHW programs. In particular, data from this study would be extremely
useful for local Medicaid managed care plans who have expressed strong interests in data
from rigorously designed clinical trials addressing the role of CHWs in delivering
culturally appropriate and effective diabetes care.
