Objective To explore how to achieve isolation of clinical trial fees and general medical expenses of hospitalized subjects through information technology.Methods This article analyzed various methods for separating clinical trials fees from medical insurance and suggested that all methods need to protect subjects'medical insurance reimbursement rights and ensure that they do not occupy medical insurance funds.Based on this principle,A clinical trial cost segregation information module was developed based on inpatient's workstation.Results Through this information module,subjects could choose their medical status according to the actual medical situation.Doctors could issue medical orders in hospital information system(HIS)according to normal medical or trail needs,change the nature of the orders by adding or deleting clinical trial tags.The system automatically intercepts the clinical trial orders for reimbursement of medical insurance,while other expenses are reimbursed according to rules of medical insurance.Conclusion The application of this information module has improved the subjects'enthusiasm and compliance to participate in clinical trials,reduced their economic burden,and ensured their rights to enjoy reimbursement of medical insurance,which can be used as a reference example for newly registered clinical trial institution.
