RESUMO
Purpose: This study aims to predict the expected cost savings associated with implementing a multidisciplinary team (MDT) approach to reduce macrovascular and microvascular complications among patients with type 2 diabetes mellitus (T2DM). Methods: This economic evaluation study was conducted in Riyadh First Health Cluster, Saudi Arabia as a predictive model conceptualized by the authors based on models used in previous studies, particularly the CORE Diabetes Model. Our model was designed based on 1) the level of glycemic control among 24,755 T2DM patients served by MDTs; 2) the expected incidence of diabetes-related complications without intervention; 3) the predicted risk reduction of developing diabetes-related complications with MDTs. Costs of complications and cost savings were then calculated and expressed as mean incremental annual cost savings adjusted for a 1% reduction in HbA1c, and a 10 mmHg reduction in systolic blood pressure (SBP). Results: Along with the expected reduction in all diabetes-related complications, the average incremental cost savings per diabetic patient is predicted to be ($38,878) with approximately ($11,108) in the year of complication onset and ($27,770) over the subsequent post-index 10-years. On adjustment of cost savings, the average incremental cost savings are predicted to be ($22,869) for each 1% reduction in HbA1c per diabetic patient and ($27,770) for every 10 mmHg reduction in SBP per diabetic patient. Conclusion: MDT as a model of care is effective in glycemic control among T2DM patients with a predicted significant reduction of all diabetes-related complications and in turn, a predicted significant cost savings.
RESUMO
OBJECTIVES: Our study aims to assess the effectiveness of implementing a case manager-led Multidisciplinary Team approach in the primary healthcare setting on improving glycemic control and reducing cardiovascular risks for T2DM patients over a 6-month period. METHODS: This retrospective record-based follow-up study was carried out on 3060 uncontrolled T2DM patients in primary healthcare centers in Riyadh First Health Cluster over a period of 6 months. The patient records are investigated and analyzed, including demographic characteristics and measurements of Hemoglobin A1c (HbA1c), Low-Density Lipoprotein Cholesterol (LDL-C), total cholesterol, and BP levels at enrollment and after 6 months of Multi-Disciplinary Team follow-up. The changes in the study variables and their correlations to each other are tested using Statistical Package for the Social Sciences software. RESULTS: At enrollment, our patients were characterized by poor glycemic control (HbAIC > 8%). Most of them have high body weight with a mean BMI of (31.2 ± 1.7), and nearly two-thirds are either hypertensive or have dyslipidemia (43.4% and 47.3% respectively). After 6 months of MDT follow-up, there is a significant improvement in glycemic control among 1971 patients (64.4%), with a reduction in the mean level of different outcomes relative to baseline HbA1c (-15%, P < .001), total cholesterol (-9.0%, P < .001), LDL-C (-11.0%, P < .001), systolic BP (-7.7%, P < .001), and diastolic BP (-10.5%, P < .001). The improved glycemic control showed a significant positive correlation with the number of MDT visits but negatively correlated with BMI and the number of comorbidities. In addition, the improvements in secondary outcomes were positively and significantly correlated with such improvements in glycemic control. CONCLUSION: Case-manager-led MDT approach significantly improves glycemic control and significantly improves control over dyslipidemia and hypertension, reducing cardiovascular risks, and unfavorable events among such diabetic patients. We highly recommend developing more MDTs, training case managers, and rigorously evaluating the MDT approach.
