Development and Implementation of a Point-of-Care Ultrasound Curriculum at the Undergraduate Medical Education Level
This study demonstrates that a simulation-based Point-of-Care Ultrasound curriculum incorporating standardized patient encounters significantly improved fourth-year medical students' knowledge, confidence, and competency in basic ultrasound techniques during their internal medicine rotations.

In modern hospitals, doctors often rely on large, stationary machines to peer inside the human body, but these devices are not always available when a patient needs them most. Imagine a physician working a night shift when a patient suddenly struggles to breathe. Waiting hours for a specialized technician to arrive with a heavy machine can delay critical care. To bridge this gap, many clinicians now carry portable ultrasound devices—small, handheld tools that use sound waves to create real-time images of the heart, lungs, and blood vessels right at the bedside. This practice, known as point-of-care ultrasound, allows a doctor to see what is happening inside a patient immediately, improving diagnostic accuracy and speeding up treatment decisions. While the technology has become common in emergency rooms and intensive care units, the question remains: are future doctors being taught how to use these tools effectively before they graduate?
A team of educators at the University of Alabama at Birmingham set out to answer this question by designing a new training program for fourth-year medical students. They recognized that while students spend years learning anatomy and physical exams, they often receive little formal instruction on how to operate ultrasound machines during their clinical rotations. To fix this, the researchers created a four-week course that combined classroom lectures with hands-on practice. The goal was not to turn students into experts in a single day, but to give them a solid foundation in scanning the heart, lungs, and major blood vessels. The curriculum was built around a specific challenge: how to teach these skills in a way that feels real and prepares students for the unpredictable nature of hospital work.
The program ran over the course of a year, involving thirty-six students who were rotating through their internal medicine internship. Before the course began, the students took a test to measure their baseline knowledge. On average, they answered less than half of the questions correctly, and many admitted they felt unsure about using the equipment. The training itself was structured into short, focused blocks. Students first learned the basics of the machine, such as how to adjust the settings and hold the probe correctly. They then moved to practical sessions where they practiced scanning models and each other to understand how to find specific views of the heart and lungs. The instructors focused on common clinical scenarios, such as checking if the heart is pumping effectively or looking for fluid around the lungs.
A unique and central part of this training was the use of simulated patients. These were actors trained to portray a specific medical case: a sixty-five-year-old man with a history of heart and lung disease who was having trouble breathing. In the final week of the course, each student had to perform a full examination on one of these actors. The students were given a brief note describing the patient's symptoms and had twenty minutes to complete the exam. During this time, they had to use the ultrasound machine to gather information, explain what they were doing to the "patient," and decide how the findings fit into the overall care plan. Faculty members and the actors themselves watched closely, using checklists to rate how well the students handled the machine, how clearly they communicated, and how they integrated the ultrasound images into their medical reasoning.
The results of the program were clear and measurable. After completing the four weeks, the students' knowledge scores jumped significantly, rising from an average of forty-five percent to seventy-six percent. More importantly, their confidence levels soared. Before the course, many students felt unprepared, but afterward, the vast majority reported feeling moderately to very confident in their ability to scan the heart, lungs, and major veins. The evaluations from the faculty and the simulated patients confirmed that the students were not just memorizing facts; they were actually performing the tasks. Most students demonstrated the ability to get clear images and use them to make clinical decisions, while also maintaining a professional and compassionate approach with the patient.
The researchers noted that this approach offered a practical and cost-effective way to teach a complex skill. By using actors and portable machines that were already available at the school, they created a realistic learning environment without needing expensive new infrastructure. The study suggests that a short, focused course can successfully equip future doctors with the ability to use bedside ultrasound, a skill that could improve patient care during busy shifts or when advanced imaging is unavailable. While the study did not track whether these skills lasted for years or directly changed patient outcomes in the long term, it proved that medical students can rapidly acquire both the technical ability and the confidence to use these tools when they need them most. The model used here, which blends classroom learning with realistic practice, offers a blueprint that other medical schools could adopt to ensure their graduates are ready to use modern diagnostic tools from day one.
