Abstract
This proposal presents an optimized, efficient and secure system designed to improve healthcare staff management in emergency situations through a complete tool to classify victims in a emergency situation according the severity of their condition, providing at the same time their location and the best route to reach them. The developed tool consists on a mobile application (assigned to medical and healthcare staff), a web service and Near Field Communication tags (assigned to victims). The mobile application supports secure communication among health staff and implements triage algorithms which result is stored in NFC tags. Apart from this, it helps to indicate which should be the next victim to be treated. The developed web service provides a global view of the emergency status and the current position of victims and staff. Data security is a key objective, overall in health applications; for this reason, tokens are used to protect the triage results before being stored in NFC tags, and the use of IDentity-Based Signcryption provides confidentiality and authentication to communications. Two different signcryption methods are used depending on the communication mode (peer-to-peer or broadcast mode).
Highlights
Nowadays, most smartphones are used to support different daily tasks, due to their small size and high performance
In order to store the triage result in Near Field Communication (NFC) stickers, an adaptation of JSON Web Token (JWT) is defined; The JSON header contains the algorithm used (HS256), and the payload is composed by the data related to the triage result, the identifier (ID) of each member of the healthcare workforce who has changed the content of the NFC sticker and a previous shared emergency code generated for each emergency situation, see Fig. 2
When health staff arrives to a victim’s location, the NFC sticker should be read with a mobile device, the person is assigned to an Advanced Medical Position (AMP), the point is marked as completed, and the status of victim is checked
Summary
Most smartphones are used to support different daily tasks, due to their small size and high performance. This work presents a system, including mHealth solutions, that improves healthcare staff management in emergency situations impacting on a better and more efficient attention to victims. The system provides a communication channel through a chat supported by Wi-Fi Direct on firs responders’ mobile phones jointly with a map that helps them to locate the victim to be treated and where the nearest point of medical attention is.
