In order to solve the problem of insufficient ability of primary cardiac electrical diagnostic experts and improve the treatment level of critical cardiovascular patients, Jiangsu Provincial People's Hospital explored and built a regional ECG diagnosis service system based on network platform support. It has realized the integrated service system of heart-level unit ECG data collection and high-end hospital ECG expert analysis and diagnosis, which effectively solves the problem that patients with critical cardiovascular diseases cannot get timely diagnosis and treatment. Jiangsu Provincial People's Hospital developed and established a regional medical ECG diagnosis platform based on the characteristics of the ECG diagnosis and diagnosis business. Using the in-hospital ECG examination and diagnosis network, the ECG examination data collected by the grassroots hospitals and community health service organizations in the provinces will be collected. After standardization and digitization, it is sent to the ECG network system server of the hospital to realize distributed data collection, diagnosis expert resource sharing, innovative development of regional ECG inspection and remote diagnosis medical service mode, effectively improve the utilization level of ECG diagnostic service resources and medical treatment. service quality.
1 Construction of regional ECG diagnostic platform
1.1 The concept of regional ECG diagnostic platform in Jiangsu Province
The regional ECG diagnosis platform in Jiangsu Province is located in the Jiangsu Province, centered on the People's Hospital of Jiangsu Province, and is connected to various community health service centers through a municipal platform to build an electrophysiological device connecting the ECG network to the hospital, and to check and diagnose the electrocardiogram. Work digitally, networked, and unified storage to the ECG platform server. Jiangsu Provincial People's Hospital or Cooperative Hospital, primary medical institutions, etc. through the network platform, using logical group management, can realize real-time access and printing of ECG data and reports, and ECG data interaction between different hospitals in the region, so that patients The ECG examinations in different medical institutions can be shared, the patients can be examined in the primary hospitals, and the tertiary hospitals can remotely assist the cooperative hospitals and primary medical institutions to diagnose through remote consultation.
1.2 Technical solutions
The core technologies of the regional ECG diagnostic platform in Jiangsu Province mainly include the following aspects.
1.2.1 Compatible with parsing data collected by different brands of ECG devices. Digitize the collection results of different ECG brand inspection equipments, obtain the original ECG inspection data, and convert the ECG data format to HL7-aECG format according to the storage and transmission of ECG data using the unified HL7-aECG standard.
1.2.2 ECG network software architecture and data exchange interface. Design ECG network software architecture and data exchange interface according to the recommended process and interaction method of IHE integration specification. The software adopts SOA service-oriented architecture to realize loose coupling between systems, facilitate system flow reorganization and optimization, and between different systems. Docking, enabling two-way delivery between ECG applications and reporting and other systems.
1.2.3 Unified storage management of ECG medical records in regional patients. The established regional ECG diagnosis platform server in Jiangsu Province stores the ECG data uploaded in different regions, uses the ECG data automatic analysis and recognition algorithm, analyzes the corresponding ECG data, and simultaneously counts the ECG data information, which can be based on the name, hospital number, and diagnosis. Doctors and other search information are used to query and review ECG reports.
1.2.4 Implementation of remote consultation of regional patients. The regional ECG diagnostic platform in Jiangsu Province maps two ports to the ECG diagnostic platform server by means of the gatekeeper of the external network server, constructs the ECG gateway model according to the HL7-aECG specification, and creates a network environment that satisfies the heterogeneous ECG device and realizes the region. The internal ECG server of each hospital is interconnected with the regional ECG diagnosis platform server of Jiangsu Province.
1.2.5 Wireless mobile intelligent terminal. Using 3G, 4G, WiFi technology and embedded system technology, the wireless portable mobile ECG inspection terminal is developed. Within the coverage of the hospital wireless intranet, the collected ECG data can be automatically uploaded to the ECG server after the acquisition is completed, outside the hospital. It can diagnose and query ECG reports in real time, and timely detect, identify, display, alarm and diagnose cardiovascular diseases.
