This pilot study serves to assess the diagnostic adequacy of Artificial Intelligence (AI)-guided point-of-care. Focused echocardiography examinations will be obtained by Anesthesiology trainees and assessed by an expert Cardiologist Echocardiographer. AI-guided echocardiography examinations will be compared to each other. AI-guided and non-AI-guided echocardiography examinations will also be compared.
This pilot study will involve Post-Graduate Year 2 Anesthesiology trainees on rotation in the Loma Linda University Medical Center operating rooms. Prior to participation, the trainees will give written informed consent to participate in the study and complete a baseline questionnaire to collect information regarding prior education in point-of-care echocardiography and the number of those examinations personally performed prior to study participation. All subjects will watch a brief training video about the AI guidance platform and participate in a hands on training session to familiarize themselves with AI guidance. When adult patients having anesthesia for procedures present with a clinical indication for peri-anesthesia point-of-care echocardiography examination, the assigned trainee will use the AI-guided system to obtain a standardized point-of-care focused cardiac examination. Subjects will be completing 11 total examinations, 10 using AI guidance, 1 without. Images of the examination will be assessed by an expert Cardiologist Echocardiographer that is blinded to the resident involved to measure diagnostic adequacy. A final non-AI-guided echocardiogram examination will be completed by the resident to measure and compare the time and adequacy of the images to the AI-guided examination images.
Study Type
OBSERVATIONAL
Enrollment
16
A wireless, AI-guided handheld ultrasound probe will be used on adult male patients who present with a clinical indication for peri-anesthesia point-of-care echocardiography examination. Residents will document personal interpretation of the completed point-of-care ultrasound (POCUS) examination, important clinical findings, and assessment of whether obtaining a formal echocardiogram is warranted on an exam assessment form. The residents will complete 11 examinations with 10 specific scans each. The first 10 examinations will be AI-guided, and the final 11th examination will be done via a standard (non-AI guided) ultrasound system to gauge the resident's growth in point-of-care echocardiography skill.

Echocardiogram Evaluation
Cardiologist will review AI-assisted echocardiogram images obtained by residents for diagnostic image quality. A rating of "Yes" will represent a diagnostically accurate result and a rating of "No" will represent an image that is not adequate for diagnostic purposes.
Time frame: Within 24 hours of AI-guided examination completion
Change in length of time of AI-assisted echocardiogram procedure
Assessment of time to complete the standardized point-of-care focused echocardiography examination will be determined by comparing time stamps on the first and last image sequence recorded. Change in this interval will be assessed between the tenth and first studies performed.
Time frame: Change in time of individual examination completion between the first AI-guided echocardiography examination performed and the tenth AI-guided echocardiography examination performed, typically one month post-enrollment
Change in echocardiogram examination image quality through comparison of AI-guided and non-AI-guided echocardiogram examination
After the 10th AI-guided point-of-care focused echocardiography examination is completed, the trainee will complete a standardized point-of-care focused echocardiography examination using a standard (not AI-guided) system. Assessment of echocardiogram adequacy, time to complete the examination, and Concordance between the trainee and Cardiologist assessments will be analyzed as described above.
Time frame: Change in time between the tenth AI-guided echocardiography examination performed and the non-AI guided cardiography examination performed, typically two months post-enrollment
