Improving diabetes care and health measures among hispanics using community health workers: results from a randomized controlled trial.

The increasing prevalence of diabetes and obesity, growing health disparities, and shortage of bilingual and culturally trained health care professionals underscore the role of trained community health workers (CHWs) to provide economically sustainable and culturally relevant services. This prospective randomized design evaluated the relative effectiveness of a CHW intervention among Hispanic persons with newly diagnosed type 2 diabetes, as compared with usual clinic practice in three inner-city health centers. In sum, 189 Hispanic patients newly diagnosed with type 2 diabetes were randomly assigned to one of three 6-month diabetes management approaches--CHW, case management, and standard provider care--and assessed for diabetes-related health measures and clinical indicators at baseline and postintervention. Participants in the CHW group achieved greater improvements than did the controls in program measures: health status, emergency department utilization, dietary habits, physical activity, and medication adherence. They also had 2.9 times greater odds of decreasing body mass index.

Effect of a nurse-directed diabetes disease management program on urgent care/emergency room visits and hospitalizations in a minority population.

OBJECTIVE: To evaluate whether nurse-directed diabetes care reduced preventable diabetes-related urgent care/emergency room visits and hospitalizations in a minority population. RESEARCH DESIGN AND METHODS: Diabetic patients who receive care in a county public health clinic were randomly selected for a Diabetes Managed Care Program (DMCP) in which a specially trained nurse followed detailed treatment algorithms to provide diabetes care for 1 year. Preventable diabetes-related urgent care/emergency room visits and hospitalizations for these patients incurred during the intervention year and the year before enrollment were compared. Preventable diabetes-related causes were defined as metabolic (diabetic ketoacidosis, hyperglycemia, or hypoglycemia) or infection (cellulitis, foot ulcer, osteomyelitis, fungal infection, or urinary tract infection). RESULTS: Use of the urgent care/emergency room and hospitalizations during the intervention year and the year prior were available for 331 patients who completed the DMCP intervention. There were 95 [corrected] total urgent care/emergency room visits and hospitalizations in the year before entering the DMCP and 52 [corrected] during the DMCP year, a 45[corrected]% reduction. Preventable diabetes-related episodes were far fewer. During the prior year, 14 patients made 15 urgent care/emergency room visits and 5 patients incurred 6 hospitalizations. During the DMCP year, four different patients made five emergency room/urgent care visits and one other patient was hospitalized. Preventable diabetes-related use was significantly (P < 0.001) lower during the intervention year compared with the prior year. Total charges for urgent care/emergency room visits and hospitalizations only (not other charges related to diabetes care) during the year before entering the DMCP were $129,176 compared with $24,630 during the DMCP year. CONCLUSIONS: When compared with usual care, nurse-directed diabetes care resulted in significantly fewer urgent care/emergency room visits and hospitalizations for preventable diabetes-related causes. Policy makers seeking to improve diabetes care and conserve resources should seriously consider adopting this approach.
