Objective: As of October, 2012, 42 states had an established Prescription Monitoring Program (PMP). Although laws vary by state, most prescribers can access PMP data, including Medical Psychologists (i.e., prescribers) in Louisiana. This poster will demonstrate how the PMP can be a useful background information gathering tool, particularly in neuropsychological evaluations. Method: This case presentation will highlight how the PMP was used to verify background information in a recent neuropsychological evaluation. The patient was a 24 year old Caucasian male who was referred by a state rehabilitation agency for neuropsychological evaluation to determine vocational placement options. Relevant patient history included a severe traumatic brain injury, secondary to a motorcycle accident, and reported past substance abuse. Results: In this case, ongoing substance abuse significantly impacted a) the diagnoses rendered in the report and b) appropriate vocational recommendations. As the patient was not forthcoming regarding his current substance use, the PMP was a useful tool in establishing the veracity of the patient's report. Conclusion(s): Neuropsychologists could benefit from the use of this unique resource, as most states now have active PMP websites. For psychologists with prescription authority, access to the PMP should not be an issue; however, even psychologists who do not prescribe could consult and collaborate with the patient's attending physician to obtain PMP data. Such data can potentially aid in the rendering of accurate diagnoses and appropriate treatment recommendations.
