HIV and Alcohol Research Center Focused on Polypharmacy (HARP)

Study Overview
=================
Brief Summary
-----------------
This pilot intervention will consist of a brief intervention for patients with HIV who take 5 or more medications and currently (within the past month) consume alcohol. The focus of this pilot will be on bothersome symptoms and the impact of alcohol use and medications on these symptoms. The rationale is that any alcohol use may interact with medications in serious ways leading to adverse outcomes, including bothersome symptoms.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: HIV Medications and Alcohol Use<br>Participants with HIV who take 5 or more medications and currently (within the past month) consume alcohol | Behavioral: IMB-motivational interviewing (MI) techniques (IMB-MI)<br>* The clinical pharmacist will employ MI in informational, participant-centered discussions in which the clinical pharmacist and participant collaboratively discuss the harms of drinking and polypharmacy (specifically alcohol interactive medications), symptoms associated with alcohol and specific medications, and how to mitigate these harms. Motivational elements include messages highlighting the participant's personal risk of bothersome symptoms from their use of alcohol and level of polypharmacy, attitude change elements to improve attitudes toward the intended behavior change, social normative support for the intended behavior change including identification of people who can support the participant in this process, and a menu of options for referrals for skill building (e.g. Social Work, meeting with the clinical pharmacist at their clinic, follow-up with the HIV clinician, alcohol-reduction programs, based on what is locally available as part of VA-based care).<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Bothersome Symptoms from baseline using the HIV Symptoms Index | The HIV Symptoms Index is a 20-item, self-reported measure that assesses presence and perceived distress linked to symptoms associated with HIV or HIV treatment. There are 5 possible responses: 0 = I don't have this symptom; 1 = It doesn't bother me; 2 = It bothers me a little; 3 = It bothers me; and 4 = It bothers me a lot, for each HIV symptom. Total score is derived by counting the number of bothersome symptoms. | baseline, immediately post-intervention, 30 days post intervention | 
| Change in Phosphatidylethanol (PEth) Levels | Change in alcohol levels assessed measuring PEth levels in the blood. PEth testing uses blood to measure alcohol use by detecting direct alcohol biomarkers in the bloodstream. A positive test indicates alcohol use. | baseline and 30 days post intervention | 
| Number of Medications Prescribed Post Intervention | The number of prescriptions prescribed post intervention will be assessed by phone contact, paper survey and electronic health record pharmacy data. | baseline and 30 days post intervention |
