Clinical Trial Summary

As a potential solution to address high rates of depression and anxiety seen in epilepsy patients and poor mental health care access, this randomized trial aims to study treatment for anxiety and depression in epilepsy taking place directly within the epilepsy clinic vs. psychiatry referral (typical care). Patients that meet eligibility criteria, including significant symptoms of depression and/or anxiety, will be randomized to the either the intervention group or the control group. Patients that do not meet eligibility requirement or decline the study intervention will have the option of participating in the survey arm of the study. The intervention will consist of an initial prescription for an FDA-approved medication to treat depression/anxiety and telephone-based chronic care management plan for repeated symptom measurement and side effect surveillance. The control group will receive usual care, which is a referral order to psychiatry placed by their treating neurologist. Participants in the survey arm of the study will complete a one time survey.

Description:

This trial is an innovative learning healthcare system approach to translate the concept of measurement-based depression care into a specialty clinic setting and extend the concept to treat depression and/or anxiety. The investigators' neurologist/APP-administered medication intervention utilizes FDA-approved drugs with advantageous features for use in epilepsy (escitalopram and venlafaxine) and a telephone-based chronic care management plan for repeated symptom measurement and side effect surveillance. The proposed intervention may overcome barriers to implementing mental health treatment interventions in generalized clinical settings by using healthcare providers commonly present in specialty clinics (physicians and APPs) along with a billable, best practices chronic care management intervention package and EMR-based clinical tools.To test this idea, the investigators seek to pilot a randomized trial of neurologist/APP medication management of depression and anxiety versus usual care with psychiatry referral in the epilepsy clinic, using epilepsy as a paradigm for chronic medical illness with high prevalence of psychiatric comorbidity. The optional survey arm is to help investigators understand the population that do not meet criteria or refuse intervention.

• Epilepsy

Intervention

Drug:
• Escitalopram 10mg
Participants will be given escitalopram 10mg by mouth daily and will be followed up with at 2, 4, 6, 8, and 10 weeks. Medication will be adjusted if side effects occur. If unable to tolerate escitalopram, then venlafaxine XR (Effexor XR) 37.5mg will be substituted.

Other:
• Referral to Psychiatry
Participants randomized to control will have a psychiatry referral order placed by the treating epileptologist under typical care circumstances. This will be an internal or external referral order based on patient preference. If external, the order will be printed along with instructions for the patient to follow to find a provider covered by insurance.
• Survey only
One time survey will be offered to individuals who are found to have anxiety or depression symptoms on screening but who are ineligible for the treatment component of the study, or who decline the treatment study.
