The regional medical information system calls for regional information resources and hospital-level information resources be interconnected and intercommunicated.To meet this requirement,a HL7 CDA-based solution was proposed based on analysis of the current hospital information resources management.An information resources service portal was built to harmonize the management of both new and old resources,and the hierarchy management based on information granularity.The technical implementation of the system is compliant with the SOA architecture and health information standards.This ensures the interconnection and intercommunication between inner information and outer one,and uses information resources in an efficient,reasonable and safe manner.

The hospital improved its pre-examination quality of laboratory medicine by means of setting up pre-examination quality management committee, full-course supervision of pre-examination process, and clarified responsibility system. Informationization means play multiple roles for the pre-examination quality, including full-course management, early warning and interception of unqualified sample. The coordinated application of multi-departments, multi-links and multi-measures can improve the pre-examination quality of laboratory medicine and ensure the quality of test results and the medical safety of patients.
