Artificial Intelligence to StrategiCally Enhance Pulmonary Embolism Response Team Activation (ASCENT)

January 29, 2024 updated by: Jun Li, University Hospitals Cleveland Medical Center

The Impact of System Wide Pulmonary Embolism Screening Program on PERT Activation, Utilization of Advanced Therapies, and 90-Day Outcomes

Pulmonary embolism (PE) remains a high mortality and morbidity disease state. We have previously shown that use of a Pulmonary Embolism Response Team (PERT) can improve overall readmission, bleeding, and mortality outcomes. Unfortunately, PERT may still be underutilized from a national standpoint and may not be readily available in underserved areas.

The utility of the current study is to investigate the implementation of an artificial intelligence (AI) program to differentiate patients at the highest risk of the PE spectrum to help efficiently identify those most appropriate for aggressive management. Furthermore, we will investigate the utility of an algorithm-driven protocol for activation of invasive interventions versus traditional PERT discussion and evaluate overall patient outcomes.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Patients obtaining a CT at University Hospitals found to have a pulmonary embolism with evidence of right ventricular strain (RV:LV > 0.9) along with an abnormal vital sign (HR > 110 bpm, RR > 30/min, SBP < 100 mmHg, or O2 saturation < 90%)
  • Patients undergoing PERT discussion as deemed appropriate by the provider

Exclusion Criteria:

  • Age <18
  • Pregnant patients. Women of childbearing age will be asked if they are pregnant before enrollment. No formal pregnancy test will be performed as a part of this study. If a patient does require invasive intervention, as part of the routine procedure for cardiac catheterization laboratory, women of childbearing age will either undergo pregnancy testing or opt-out per their own discretion
  • Patients unable to perform 6MWT (e.g., lack of one or both legs) will not be included in the randomization. They will be included in the observation for routine treatment

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Algorithm-driven
Device: Aidoc- Algorithm-driven decision making
Following alert by AI program for PE, patients are randomized either to PERT traditional multidiscplinary team discussion (comparator) or to an algorithm-driven protocol (experimental) to decide on treatment strategy. Treatment strategy may be early invasive-technique or watchful waiting.
Active Comparator: PERT-driven
