Evaluating the Preferences and Tradeoffs of AI-based Electronic Consultations for Older Adults in Primary Care

August 9, 2026 updated by: Gary Weissman, University of Pennsylvania

Evaluating the Safety and Appropriateness of AI-based E-Consults for Older Adults in Primary Care

Electronic consultations, or e-consults, let a primary care doctor request medical advice from a specialist without requiring the patient to attend a separate visit. Artificial intelligence (AI) systems may be able to provide this type of advice, potentially making e-consults faster and less costly. However, whether AI-based e-consults are acceptable may depend on how patients and clinicians weigh factors such as who provides the advice, how quickly it is received, its cost, and its quality.

The purpose of this study is to examine how older adult patients and primary care clinicians weigh these factors when comparing e-consults produced by a human specialist with those produced by an AI system. In the study, participants will complete a one-time survey in which they compare sets of two hypothetical e-consults. Each e-consult will include a different combination of features, such as whether the advice comes from a human or AI, the expected wait time, the cost, and the quality of the advice. This study will estimate how much patients and clinicians value each feature in an e-consult. The findings will inform the potential future AI e-consults, so they better reflect patient and clinician preferences.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Electronic Consultation Systems
Participants will review 2 different e-consult systems, which will differ in terms of quality, cost, wait time, and source of the e-consult. Participants will then indicate a preference for 1 e-consult system in each set.
Participants will review these e-consults systems via a one-time survey lasting about 15 minutes.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Preferences and Tradeoffs of Attributes of Electronic Consults
Time Frame: From enrollment to the end of the survey, approximately 15 minutes
Participants will review 12 sets comparing 2 hypothetical e-consults. Each e-consult is defined by five attributes: the source (i.e., AI vs. human), wait time, cost, and quality of the e-consult, as well as, whether follow-up questions can be asked. For each set, the outcome is the participant's selection of one e-consult over the other. We will analyze the results of the discrete choice experiment using mixed-effects logistic regression adjusted for each attribute value with crossed random effects (intercepts) for participant and task.
From enrollment to the end of the survey, approximately 15 minutes

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Health Numeracy Measured by the Short Numeracy Understanding in Medicine Instrument
Time Frame: From enrollment to the end of the survey, approximately 15 minutes
Health numeracy will be measured using the 8-item Short Numeracy Understanding in Medicine instrument (S-NUMi). Each correct response contributes one point to the total score. Total scores range from 0 to 8, with higher scores indicating greater health numeracy.
From enrollment to the end of the survey, approximately 15 minutes
