The Impact of TMS Ultrasound Curriculum on Learning Outcomes of PGY Emergency Physicians: A Retrospective Study

This single-center retrospective study evaluates the effectiveness of the Training Management System (TMS) ultrasound curriculum on the learning outcomes of PGY emergency physicians. By analyzing test scores and course participation data from 2018 to 2025, the study investigates whether blended learning improves PoCUS proficiency and explores its potential role in enhancing ultrasound education for junior physicians.

Detailed Description

Current point-of-care ultrasound education faces multiple challenges. Traditional teaching methods, such as didactic lectures and bedside one-on-one training, are constrained by time, clinical workload, and faculty availability, leading to inconsistent learning outcomes. Additionally, PGY physicians, due to their limited clinical experience, struggle to develop proficiency in ultrasound in a randomized learning environment. The quality of ultrasound image acquisition and diagnostic accuracy is also highly dependent on the operator's experience. In recent years, online learning platforms, such as the Training Management System, have been introduced to enhance learning flexibility. However, the long-term impact of such platforms on trainees' clinical application remains unclear. This study aims to evaluate the impact of the TMS ultrasound curriculum on the learning outcomes of PGY emergency physicians and explore the feasibility of a blended learning approach in improving ultrasound skill application. This single-center retrospective study analyzes test data from PGY trainees who participated in emergency PoCUS training between 2018 and 2025, including post-course test scores, objective structured clinical examination scores, and self-reported TMS course participation. The findings of this study may provide insights into the effectiveness of online and blended learning models in developing ultrasound proficiency among junior physicians and inform future medical education curriculum design.

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

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

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Postgraduate Year (PGY) trainees are newly graduated medical doctors undergoing structured clinical training as part of their early postgraduate education. In Taiwan, the PGY program is designed to enhance foundational clinical competencies through rotations across various medical specialties, including emergency medicine.

Description

Inclusion Criteria:

  1. PGY trainees who participated in the Department of Emergency Medicine ultrasound training program during the study period.
  2. Trainees with complete course participation records and assessment results.

Exclusion Criteria:

  1. Non-PGY participants (e.g., senior residents, attending physicians, medical students).
  2. Incomplete assessment data that prevents a full evaluation of learning outcomes.
  3. Any abnormal data not meeting study criteria (e.g., recording errors or duplicate entries).

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
PGY trained with TMS ultrasound curriculum
PGY physicians trained with the TMS ultrasound curriculum participated in a structured, blended learning program that combined online modules with hands-on clinical training. The Training Management System (TMS) provided flexible, self-paced learning opportunities to reinforce foundational knowledge, while in-person sessions focused on skill application and image acquisition.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean Post-Course Test Score
Time Frame: From enrollment to the end of the test at 8 weeks
Mean score of participants on the post-course knowledge test (range: 0-100 points; higher scores indicate better knowledge acquisition)
From enrollment to the end of the test at 8 weeks
Mean OSCE Rating Score
Time Frame: From enrollment to completion of OSCE at 8 weeks.

Mean score of participants on the Objective Structured Clinical Examination (OSCE) assessing ultrasound performance. The OSCE includes structured evaluation of the following domains:

Image Acquisition Quality: Clarity and completeness of target anatomical structures (e.g., blood vessels, Morrison's pouch, spleno-renal recess, cul-de-sac).

Diagnostic Accuracy: Ability to correctly interpret ultrasound findings and reach an appropriate clinical diagnosis.

Scanning Technique and Efficiency: Smoothness, probe handling, and adherence to scanning protocols.

Each domain is rated on a 10-point Likert scale (1 = Poor, 10 = Excellent), with higher scores indicating better clinical performance. The overall OSCE score is calculated as the mean of these domain scores.
From enrollment to completion of OSCE at 8 weeks.

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
