The Effect of a Telephone-based Health Coaching Disease Management Program on Medicaid Members With Chronic Conditions

Objectives: To examine the effect of a telephone-based health coaching disease management program on healthcare utilization and expenditures in Medicaid members with chronic conditions. Research Design: Using a difference-in-differences analysis, we examined changes in hospitalizations, emergency department (ED) visits, ambulatory care visits, and Medicaid expenditures among program members for 1 year before and 2 years after their enrollment compared with a matched comparison group. Subjects: Medicaid members aged 18 to 64 with a diagnosis of qualifying chronic conditions and 2 acute health service events of hospitalizations and/or ED visits within a 12-month period. Results: Changes in acute hospitalizations, ambulatory care visits, and Medicaid expenditures before and after program enrollment were similar between the 2 study groups. However, during the second year after enrollment, program members had a significantly smaller decrease in ED visits than the comparisons (8% in program members and 23% in comparisons, P value = 0.03). Conclusions: Compared with a matched comparison group, the telephone-based health coaching disease management program did not demonstrate significant effects on healthcare utilization and expenditures in Medicaid members with chronic conditions.
