NCT05816473

Brief Summary

The purpose of this research study is to measure the effect on of a large language model interface on the usability, attitudes, and provider trust when using a machine learning algorithm-based clinical decision support system in the setting of bleeding from the upper gastrointestinal tract (upper GIB). Specifically, the investigators are looking to assess the optimal implementation of such machine learning algorithms in simulation scenarios to best engender trust and improve usability. Participants will be randomized to either machine learning algorithm alone or algorithm with a large language model interface and exposed to simulation cases of upper GIB.

Outcome Measures

Primary Outcomes (1)

  • Median Change in Attitudes Towards Machine Learning Algorithms in Clinical Care Using UTAUT

    The study will use a common set of dependent variables to assess baseline and post-intervention attitudes towards machine learning algorithms in clinical care using an adapted Unified Theory of Acceptance and Use of Technology (UTAUT) survey assessing perceived usefulness of the system, perceived ease of use, attitudes towards using it, behavioral intentions, and trust, measured with a 5-point Likert scale. Percent change in UTAUT survey response between Large Language Model-based Interaction and Machine Learning Dashboard at recruitment prior to administration of scenarios and immediately after completion of scenarios. The difference in time between the two will be approximately 60 minutes. Higher change indicates greater acceptance/intention to use the GutGPT+Dashboard.

    Approximately 60 minutes

Secondary Outcomes (1)

  • Clinician Decision Making of Triage of GI Bleeding

    Approximately 60 minutes

Study Arms (2)

Large Language Model-based Interaction

EXPERIMENTAL

LLM-powered chatbot with the machine learning dashboard to provide the risk assessment and provide rationale based on interpretability metrics provided by the dashboard in which study participants can directly interact with using natural language. Participants will be provided the Generative Pre-trained Transformer (GPT) chatbot powered machine learning model dashboard.

Other: LLM

Machine Learning Dashboard

NO INTERVENTION

Machine learning algorithm output with an interactive dashboard that can be used to explain, or interpret the input factors that contribute most towards the generated risk score. Participants will have access to the machine learning dashboard only.

Interventions

LLMOTHER

Use of a Large Language Model (LLM) chatbot interface to Interact with the Machine Learning Algorithm and interpretability dashboard.
