Improved Diabetes Control Through a Provider-Based Disease Management Program

Objective: The primary aim of this study was to evaluate the effectiveness of a newly implemented hospital-based diabetes mellitus disease management program. A secondary aim was to determine if relationships existed among variables. Design and setting: Effectiveness was evaluated in terms of glycemic control, post-program acute care resource utilization, adherence with American Diabetes Association (ADA) standards of care, and health-related quality of life. Participants in the Diabetes LifeCare program (DLC) received all standards of care which included diabetes self-management education, medical management by a primary care provider (PCP) supported by an evaluation and recommendations by an Advanced Practice Registered Nurse (APRN), nutritional counseling and at minimum, quarterly follow-up appointments for 1 year. Patients: Patients who were aged >=18 years and referred to the DLC program with new a diagnosis or history of type 1 or 2 diabetes mellitus. Main outcome measures and results: Results demonstrated that at 3 months after enrollment in the DLC, participants in the study with available data (n = 142) had a mean decrease in predominant glycosylated hemoglobin (HbA1c) values from 9.31 to 7.21 (p < 0.001). The HbA1c value for participants with data at the 6-month visit (n = 66) decreased from 9.23 to 7.22 at 3 months and to 6.80 at 6 months (p < 0.001). At baseline, 52 of the 142 participants (36.5%) had HbA1c values less than 8.0, compared with 107 patients (75.4%) at 3 months (p < 0.0001). A total of 185 of 227 patients (81.5%) received eye examinations as per ADA guidelines. A total of 225 of 227 patients (99.1%) were in compliance with the ADA guidelines for nutritional counseling as a result of participation in the program. On the Physical Component Summary, their mean scores were 42.75 [standard deviation (SD) = 11.17] at enrollment, compared with 45.12 (SD = 10.52) at 3 months (p < 0.001). The Mental Component Summary score increased from 47.52 (SD = 11.90) to 50.83 (SD = 10.47) [p < 0.001]. Regarding resource utilization, during the follow-up period only 3 of 227 patients had emergency room visits and there were no inpatient visits for acute problems related to diabetes. Conclusions: Our results show that, in the short term, significant improvement in glycemic control can be achieved through a comprehensive program of patient education and management, that includes collaborative efforts with the patient's primary care provider. High rates of eye and foot examination can also be attained by reinforcing patient involvement and admissions for acute metabolic complications can be minimized.
