Abstract

Objective: To analyze the price changes of orphan drugs before and after the reform. To explore the impact of the abolition of drug price control and market liberalization on the price of orphan drugs. And to provide reference for the formulation of policies related to orphan drugs. Method: We used drug price data monitored by Beijing Municipal Bureau of Health from February 2014 to June 2017. 32 kinds of 12222 orphan drug data were extracted. Based on the interrupt time-series model and the accumulation of drug price differences frequency, this research analyzes and compares the price level of orphan drug before and after the deregulation. And the impact of reform on the price of orphan drugs were put forward. Results: After the deregulation, the orphan drug price level increased significantly (slope change amount β3=3.45×10-1, P <0.05). In 2014, 1.77% of the orphan drugs were at high price differences, and 1.22% in 2015, compared with 2.57% in 2016 and 4.25% in 2017. Conclusion: After the deregulation, the Laspeyres index level of orphan drugs increased significantly, and the situation of high price differences drug became more serious. It is difficult to improve the accessibility of orphan drugs by market-oriented control measures alone. A better pricing mechanism needs to be introduced to protect the rights and interests of patients with rare diseases.
