Abstract:

To gain control over the ever increasing costs associated with pharmaceuticals, especially resulting from those individuals with chronic illnesses, Medicaid Agencies often implement Preferred Drug Lists (PDL). In such programs, Medicaid patients can only select their common medications, without special permission, from this PDL. The Alabama State Medicaid Agency's current PDL program has been shown to be effective with respect to the overall pharmaceutical costs. However, the agency wanted to make sure that that the PDL does no have an adverse effect on total medical or non-pharmaceutical costs. For example, would a specified PDL lead to an increase in disease related emergency room visits?
