NCT06950333

Brief Summary

The goal of this prospective observational study is to develop and assess the core ultrasound applications for emergency medical technicians (EMTs) in Taiwan. The study focuses on advanced emergency medical technicians (EMT-Ps) and their ability to perform point-of-care ultrasound (POCUS) in prehospital settings. The main questions it aims to answer are: Can a standardized POCUS training program improve EMT-Ps' competency in ultrasound applications? What is the reliability and validity of the newly established POCUS assessment modules for EMT-Ps? Researchers will compare trained EMT-Ps' ultrasound proficiency and clinical decision-making before and after training to see if structured POCUS education enhances diagnostic accuracy and patient care in prehospital settings. Participants will: Attend a structured POCUS training program, including lectures and hands-on practice with standardized patients and simulation models. Undergo competency assessments, including written exams, objective structured clinical examinations (OSCEs), and image interpretation tests. Perform ultrasound scans on actual patients in prehospital settings, focusing on trauma, respiratory distress, stroke, and cardiac arrest cases. Receive feedback and participate in follow-up assessments to evaluate knowledge retention and clinical application.

Outcome Measures

Primary Outcomes (1)

  • Ultrasound Image Quality Score for Target Structure Visualization

    The score of ultrasound images assessing the visualization quality of target anatomical structures (e.g., blood vessels, Morrison's pouch, spleno-renal recess, cul-de-sac), evaluated using a standardized 10-point image quality rating scale (1 = Poor, 10 = Excellent). Each ultrasound image receives an overall score reflecting the adequacy of target structure visualization, as rated by trained reviewers.

Study Arms (1)

EMT who receive POCUS curriculum

EXPERIMENTAL

This arm includes certified advanced emergency medical technicians (EMT-P) who are enrolled in a structured point-of-care ultrasound (POCUS) education program developed specifically for prehospital providers in Taiwan. Participants receive a four-hour training module composed of didactic instruction and hands-on practice focused on trauma (FAST), dyspnea (lung ultrasound), suspected stroke (carotid Doppler), and cardiac arrest (focused cardiac ultrasound). Post-training assessments include written exams and objective structured clinical examinations (OSCEs). Participants will also complete follow-up assessments at six months and participate in supervised prehospital ultrasound scanning during real-world EMS missions.

Other: POCUS education curriculum

Interventions

The training includes a 4-hour curriculum consisting of a 1-hour didactic session covering ultrasound principles and key applications, followed by 3 hours of hands-on practice using standardized models or phantoms under instructor supervision. Core scanning topics include Focused Assessment with Sonography for Trauma (FAST), lung ultrasound for dyspnea, carotid Doppler for suspected stroke, and focused cardiac ultrasound for cardiac arrest. Post-training assessments include a written test and an Objective Structured Clinical Examination (OSCE).

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients presenting with one of the following conditions in the prehospital setting:
  • Trauma Dyspnea (shortness of breath) Suspected stroke Out-of-hospital cardiac arrest (OHCA)

You may not qualify if:

  • Patients with hemodynamic instability or critical conditions requiring immediate resuscitation, making them unsuitable for focused prehospital ultrasound performed by EMT-Ps.
  • Patients under the age of 18.
