Evaluating the Cost-Effectiveness of a Telemedicine-Based Neurosurgical Triage Strategy for Traumatic Brain Injury
This study demonstrates that a telemedicine-based neurosurgical triage protocol for mild traumatic brain injury is a cost-effective, high-value strategy that significantly reduces healthcare costs and unnecessary transfers while maintaining patient safety and improving triage accuracy compared to a universal transfer approach.

Every year, millions of people in the United States suffer mild injuries to the brain, often from falls or bumps that leave them dazed but conscious. When these patients arrive at a local emergency room, doctors face a difficult choice. Standard practice has long been to play it safe: if a scan shows even a tiny amount of bleeding inside the skull, the patient is often sent by ambulance to a major, specialized trauma center. This happens out of an abundance of caution, fearing that a small injury might suddenly get worse. However, this reflexive transfer creates a ripple effect. It ties up expensive ambulances, clogs the emergency rooms of top-tier hospitals, and exposes patients to the stress and risks of a long ride, all for injuries that rarely require surgery. The question facing modern medicine is whether there is a smarter way to sort these patients—one that keeps them safe without wasting resources.
A team of researchers at Beth Israel Deaconess Medical Center in Boston decided to test a different approach using telemedicine. Instead of automatically sending every patient with a mild brain injury to a specialist, they set up a system where a neurosurgeon at the main hospital reviews the patient's scan and medical history via video call while the patient is still at the local hospital. This "Tele-TBI" protocol allows the specialist to give a real-time opinion on whether a transfer is truly necessary. The researchers wanted to know if this method could keep patients safe while saving the healthcare system a significant amount of money. They looked back at 127 patients who were evaluated using this new system over a period of time, comparing the actual outcomes and costs against what would have happened if every single one of those patients had been transferred to the big hospital regardless of their condition.
The results of this review were striking. Of the 127 patients evaluated through the telemedicine system, only six were actually transferred to the tertiary center. This means that for the vast majority of people, the local doctors, guided by the remote expert, determined that the patients could be treated safely where they were. In fact, only one person out of the entire group eventually needed a surgical procedure, and that was discovered later during a follow-up visit, not because of a missed emergency. Crucially, no one died from a delayed brain injury or a missed need for surgery. The system worked exactly as intended: it identified the few patients who truly needed advanced care while allowing the rest to stay close to home.
When the researchers calculated the financial impact, the difference was substantial. Treating these patients through the telemedicine triage system cost the healthcare network an average of $877 per person. In contrast, the researchers estimated that if every single patient had been transferred to the major center as a precaution, the cost would have jumped to $1,816 per person. This represents a saving of nearly $940 for every patient managed locally. Over the course of the study, this approach saved the system more than $119,000. The analysis showed that the telemedicine strategy was not only cheaper but also more accurate at deciding who needed help. It successfully avoided unnecessary transfers, which often result in patients being discharged from the big hospital without ever receiving treatment, while still catching the rare cases that required intervention.
The study also looked at what happened to patients over the following three months. While some patients returned to the emergency room, most did so for reasons unrelated to their brain injury, such as falls or other medical issues. The few who returned for brain-related concerns were handled appropriately, and the two deaths that occurred in the group were due to general frailty and age, not the brain injury or the triage decision. The researchers used computer simulations to test how robust these findings were, changing various assumptions about costs and transfer rates. In more than 99 percent of these simulated scenarios, the telemedicine approach remained the better choice, proving that the savings and safety were not just a lucky fluke but a consistent result.
This work suggests that the old habit of transferring every patient with a minor brain bleed to a major trauma center is no longer the most efficient or necessary path. By using video calls to connect local doctors with specialists, hospitals can make more precise decisions. This keeps patients in their local communities, reduces the burden on overcrowded trauma centers, and saves money without compromising safety. The study provides strong evidence that a high-tech, remote consultation can be a practical, everyday tool for managing trauma, ensuring that the right patients get the right care at the right place.
