Objective:To understand the impact of adjusting national drug reimbursement list(NDRL) have on the benefits of patient covered by Basic Health Insurance ( BHI ) , medical insurance fund expenditure and specific drug marketing . Methods: Based on the survey data of medical service utilization situation of national inpatients participated BHI, to summarize and analyze the change of drug usage from 2009 to 2011. Results: In 2011, the drug expense of the national inpatient covered by BHI is approximately 132.7 billion yuan, increased by 37% compared to that of 2009; among which, the expense of entry drug accounts for about 76% out of the total drug use. In 2011, new increased expense on drug use is 13.5 billion, which increased to 98% compared to that of 2009. Conclusion:Adjustment of NDRL had little effect on total drug expenses increasing, but lead changes of the drug expense structure; and expense on some new entry drugs increased obviously. The focus of future adjustment of NRDL could gradually transfer from guaranteeing on basic medicine use to the promotion on clinical rational drug use.
