Abstract
Emergency department overcrowding has become a problem over countries in recent years. The main purpose of this research is to increase the administrative efficiency with the help of information communication technology. In this study, we proposed a mobile-based indoor positioning and caregiver-patient communication system, which aims to establish a seamless emergency service for ubiquitous healthcare by using the mobile application (APP) and web technology integrated with the hospital information system (HIS). The overall process flow of the emergency service will be more digitized, transparent and simplified. Both patients and medical practitioners could obtain the benefits from our system. For the healthcare providers, they can utilize the indoor positioning function of the system to manage patients’ locations via the mobile or web application. They can also communicate to each other in an efficient way through this system. For the patients, they are able to receive sufficient information to understand their medical status in order to reduce their anxieties of waiting with the help of mobile APP. We use the Bluetooth Low Energy (BLE) technology and Received Signal Strength (RSS) based localization method with the mobile devices to estimate the patients’ locations. Several experiments were conducted in the test-bed environment and emergency department. Our positioning algorithm achieves 97.22% and 92.95% (95% Confidence Interval = 95.90% ─ 98.55% and 88.88% ─ 97.02%) accuracy of classification in test-bed environment and emergency department. As the result, our mechanism is reliable enough to satisfy the need for medical staff to track the locations of their patients.  In conclusion, the system allows emergency services to be more transparent and increases the interaction among doctors, nurses and patients as well as their relatives. With this system, the procedures of emergency services will be better understood. Healthcare providers could have more complete information to take care of patients and to realize the patient-centered care.
