Introduction to Edge Computing in Healthcare
Edge computing in healthcare represents a significant shift in how medical data is processed and utilized. It involves processing data at or near the location where it's generated – in clinics, hospitals, or even directly on patient devices outside of clinical settings. This approach contrasts with traditional cloud computing, where data is sent to remote servers for processing. By enabling data processing closer to the source, edge computing enhances the speed and efficiency of healthcare services.
Edge Computing in healthcare plays a crucial role in supporting clinical decision-making. Modern health systems are integrating this technology to improve patient care. This integration has led to the introduction of various medical devices, ranging from wearables to AI-powered imaging systems. These devices provide real-time data, like heart rate or blood pressure, which are essential for timely intervention in patient care.
One of the key advantages of edge computing in healthcare is its ability to bring data processing and analytics closer to where data is generated. This proximity is crucial in scenarios like remote patient monitoring or emergency care where quick decision-making based on real-time data is vital. For instance, AI-enabled imaging models at the edge can expedite the review process for radiologists by prioritizing critical images. Similarly, wearables and health monitors can send crucial patient data to relevant medical devices, aiding in more efficient patient care management.
In addition to improving patient care, edge computing offers significant financial and operational benefits. By processing data locally, healthcare providers can manage the unprecedented volumes of data generated by various medical devices more efficiently. This local processing reduces bandwidth costs and helps in maintaining privacy and compliance with regulations like HIPAA, which is vital for handling sensitive health information.
Moreover, edge computing in healthcare is not just about processing data but also about enhancing the capabilities of cloud computing. It enables healthcare providers to strategically use cloud or edge computing based on needs, costs, and benefits. This flexible approach allows for optimized data management, which is increasingly important as healthcare systems deal with growing amounts of data.

The integration of 5G technology in ambulances provides low-latency, high-bandwidth capabilities essential for real-time communication and data transfer. For example, smart ambulance systems developed by companies like Excelerate and Visionable enable seamless data transfer between ambulances and hospitals. This technology allows medical professionals in the ambulance to connect with hospital staff via video link, enabling consultations and diagnoses to begin before the patient reaches the hospital. This is particularly effective in stroke patients, where every minute counts. The technology has been found to reduce the time to treatment, significantly improving patient outcomes.
Smart Equipment and IoT Integration
Ambulances are equipped with advanced medical devices, such as remote ECG machines, that can communicate directly with hospital systems, transmitting results in real-time. This allows for more accurate diagnoses and treatment plans to be made en route. With the support of technologies like AR and VR, paramedics can also receive guidance from remote clinicians to perform emergency procedures.
Network Slicing for Reliable Connectivity
The use of network slicing in 5G technology, as demonstrated by Chunghwa Telecom in collaboration with Ericsson, ensures isolated network slices for ambulances. This feature allows for the seamless transmission of real-time patient data and high-resolution 4K videos, facilitating remote diagnosis and decision-making. Network slicing ensures that patient information is available to clinicians through a high-speed and stable network, leading to more efficient care.
Advanced Navigation and RFID Technology
Smart ambulances utilize GPS for real-time traffic monitoring to optimize routes, ensuring the fastest possible response time. Additionally, RFID technology is employed to track medical equipment, monitor expiration dates, and ensure timely restocking. This reduces the time needed for inventory management, allowing EMS teams to focus more on patient care.
Remote patient monitoring (RPM) with edge computing
Remote patient monitoring (RPM) with edge computing in healthcare is increasingly being recognized as a transformative approach. Edge computing allows for real-time data processing and analysis close to the source of data generation, such as medical devices like glucose monitors and blood pressure cuffs. This technology is particularly crucial for applications requiring rapid data analysis and decision-making, like medical imaging and emergency situations. For instance, the transmission of large medical images, which can be between 3GB to 6GB each, to centralized servers is often too slow and costly for cloud computing. Instead, edge computing processes these images quickly and efficiently, directly at the point of care, enhancing the speed and quality of medical interventions.
