Effect of a diabetes management program on processes of care performed and cost
The aim of the study presented here is to determine if the rate of performing the recommended processes of care differed between members enrolled in the BlueCross BlueShield of Rhode Island (BCBSRI) Diabetes Incentive Program and a comparison group of BCBSRI members having diabetes that were not enrolled in this program. We will also determine whether the care management program affected the average per member cost for medical claims, prescription drug claims, and total claims. Research was performed using a retrospective cohort study design of members with diabetes enrolled in a health care plan. Bivariate analysis measured the degree of association of intervention status with the outcome of all processes of care performed. A multivariable logistic model evaluated intervention impact through a manual backward stepwise process. Also, a univariate model with adjustment through propensity scores was used to evaluate group status impact. A Wilcoxon rank-sum test was used to evaluate differences between the median intervention and non-intervention cost values. Odds ratios for rates of performing the recommended care processes among the intervention group as compared with the non-intervention group were 1.052 (95% CI 0.894 – 1.238) for the bivariate model; 1.060 (95% CI 0.898 – 1.251) for the fitted multiple logistic model; and 1.094 (95% CI 1.033 – 1.158) for the model adjusted using propensity scores. The intervention group did have lower medical care cost and total cost than the non-intervention group but the differences between the groups in regards to medical and total cost were not statistically significant.
