The electronic medical record system (EMR) developed by Huahaixin provides internal use for medical institutions, using electronic computers to store, manage, transmit, and reproduce digital medical records of patients. Based on this, it fully considers the confidentiality of patient information and improves service functions such as medical quality and treatment efficiency. There are several functional modules in the system, including outpatient doctor workstation, inpatient doctor workstation, inpatient nursing electronic medical record system, and medical record quality control system.
