Evaluating a Clinical Decision Support Tool for Antiretroviral Therapy Optimization

October 20, 2025 updated by: Hayoun Lee, Keck School of Medicine of USC

This study is testing software designed to help healthcare providers choose the best HIV treatment combinations for their patients. HIV medicines, known as antiretroviral therapy (ART), can be complex to manage because the right regimen depends on many factors-such as drug resistance, other health conditions, and medication schedules. Many people with HIV are cared for by general clinicians who may not have access to HIV specialists, which can make treatment decisions more challenging.

In this study, healthcare providers will use patient cases to compare standard HIV treatment resources with a new clinical decision support tool that gives evidence-based ART recommendations at the point of care.

The investigators hypothesize that using the tool will help providers select treatment plans that better match clinical guidelines, make decisions faster, reduce mental effort, and increase overall satisfaction with the prescribing process.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: smART
smART (Smart Antiretroviral Therapy Assistant): a digital clinical decision support tool that provides personalized, guideline-based HIV treatment recommendations.
smART is a single-page, offline clinical decision support application that generates personalized HIV treatment recommendations by evaluating over 50,000 possible antiretroviral combinations. The user inputs patient-specific data including genotypic resistance profile, comorbid conditions, drug allergies, concomitant medications, and reproductive status (pregnant or planning pregnancy). smART performs all computations locally and does not store any patient information, ensuring complete data privacy.
Active Comparator: Traditional Prescribing resources
standard online resources commonly accessed in HIV care, including the Stanford HIV Database, the IAS-USA Drug Resistance Mutations Chart, and the NIH HIV Clinical Guidelines.
No additional interventions beyond standard clinical practice will be implemented for study participants. Treatment decisions will be guided by established HIV resources, including the Stanford HIV Database, the IAS-USA Drug Resistance Mutations Chart, and the NIH HIV Clinical Guidelines.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Adherence of Prescribed ART Regimens to Evidence-Based Recommendations
Time Frame: Assessed at completion of each patient prescribing session at Day 1
Proportion of antiretroviral therapy (ART) regimens that align with guideline-based recommendations. A regimen is considered adherent if it contains at least three fully active agents (defined as a total drug susceptibility score ≥280) and is not contraindicated based on patient-specific factors identified by the smART tool, including allergies, comorbidities, concomitant medications, pregnancy status, and/or major guideline restrictions.
Assessed at completion of each patient prescribing session at Day 1

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proportion of virally suppressed individuals
Time Frame: Assessed at between 1 month and 6 month after completion of each prescribing session
Viral suppression rates
Assessed at between 1 month and 6 month after completion of each prescribing session
