Diabetes care management participation in a primary care setting and subsequent hospitalization risk.

Scant evidence exists that examines the impact of participation in primary care diabetes management programs and their educational components on the risk of subsequent significant patient morbidity. This study examined the association between participation in a diabetes management program in a primary care setting and the risk of subsequent hospitalization. Ten thousand nine hundred eighty patients with diabetes mellitus receiving some type of treatment in a large primary care clinic network in Houston, TX were examined for incidence of hospitalization in the year 2002. Information from the year preceding the hospitalization was obtained on several demographic, clinical, and diabetes care management participation related variables. Multivariate logistic regressions were used to examine the relationship between primary care diabetes management participation as well as individual educational components and the likelihood of subsequent-year hospitalization. Patients participating in some type of primary care diabetes management were 16% less likely to have an incidence of hospitalization (p = 0.05). When individual educational components of the diabetes care management program were examined, diabetes education sessions were more beneficial than certified diabetes educator visits in reducing the incidence of hospitalization. Patients with controlled blood glucose levels and a diabetes education session seemed to have the most significant reduction in hospitalization risk (odds ratio [OR] = 0.62; 95% CI: 0.40, 0.95). There seem to be beneficial effects associated with participation in primary care diabetes management programs in terms of reduced hospitalization risk. Attendance at diabetes educational sessions in primary care settings coupled with maintenance of blood glucose control seem to be associated with greatest risk reduction.
