Background Although African American adults bear a disproportionate burden from diabetes mellitus (DM), few randomized controlled trials have tested culturally appropriate interventions to improve DM care. Methods We randomly assigned 542 African Americans with type 2 DM enrolled in an urban managed care organization to either an intensive or minimal intervention group. The intensive intervention group consisted of all components of the minimal intervention plus individualized, culturally tailored care provided by a nurse case manager (NCM) and a community health worker (CHW), using evidence-based clinical algorithms with feedback to primary care providers (eg, physicians, nurse practitioners, or physician assistants). The minimal intervention consisted of mailings and telephone calls every 6 months to remind participants about preventive screenings. Data on diabetic control were collected at baseline and at 24 months by blind observers; data emergency department (ER) visits and hospitalizations were assessed using administrative data. Results At baseline, participants had a mean age of 58 years, 73% were women, and 50% were living in poverty. At 24 months, compared with the minimal intervention group, those in the intensive intervention group were 23% less likely to have ER visits (rate difference [RD], −14.5; adjusted rate ratio [RR], 0.77; 95% confidence interval [CI], 0.59-1.00). In on-treatment analyses, the rate reduction was strongest for patients who received the most NCM and CHW visits (RD, −31.0; adjusted RR, 0.66; 95% CI, 0.43–1.00; rate reduction ↓ 34%). Conclusion These data suggest that a culturally tailored intervention conducted by an NCM/CHW team reduced ER visits in urban African Americans with type 2 DM.

BACKGROUND: Excellent diabetes care and self-management depends heavily on the flow of timely, accurate information to patients and providers. Recent developments in information technology (IT) may, therefore, hold great promise.

There is growing evidence that emerging IT may improve diabetes care. Future research should characterize benefits in the long term (>1 year), establish methods to evaluate clinical outcomes, and determine the cost-effectiveness of using IT.

The Social Problem-Solving Inventory--Revised, Short Form, was administered to 65 urban African Americans with type 2 diabetes to examine association of generic problem-solving styles and orientation with hemoglobin A1C (A1C). Eighty-five percent of participants had total social problem-solving scores in the Average range or higher. In linear regression models adjusted for education, each interquartile increase in impulsive/careless score was associated with a 0.82 increase in A1C (%) (p = 0.01), and each interquartile increase in avoidant score was associated with a 1.62 increase in A1C (%) (p = 0.004). After adjusting for depressive symptoms, the association of impulsive/careless style with A1C was attenuated, while the association of avoidant problem solving with A1C remained significant (p = 0.01). Associations of rational problem-solving style, positive orientation, and negative orientation with A1C and health behaviors were not statistically significant. Ineffective problem-solving styles may prove to be important targets for intervention to improve glycemic control.
