Objective To assess the quality of budget impact analysis in China and Canada. Methods We searched databases including PubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP from inception to 1st November, 2016, to collect studies about budget impact analysis. Two reviewers independently screened literatures, extracted data and assessed the quality of included studies. Results 27 literatures were included. The mean grades of Chinese and Canadian literatures were 3.8 and 5.5, respectively. Some Chinese studies did not explicitly clarify the research perspective. Few studies in China were conducted according to budget holders’ perspective and with a short time horizon, or examined the results using sensitivity analyses responsive to the uncertainty surrounding future market developments, or compared between current and comparator scenarios. These deficiencies were not conducive to scientific and rational decision-making. Conclusion The quality of budget impact analysis is relatively low in China. It is needed to establish uniform budget impact analysis guideline to improve quality to guide decision making.
As an important auxiliary means of pharmacoeconomics evaluation, budget impact analysis can effectively measure the affordability of medical insurance fund, and plays a significant role in the process of medical insurance access negotiation, adjustment of medical insurance reimbursement directory and establishment of payment price. The quality of budget impact analysis data has a great impact on the analysis results and the scientific decision-making. When the existing data cannot meet the requirements of the paper, relevant software is needed to carry out Delphi method to ensure the data accuracy. Infopoll is a powerful, easy-to-use application that designs consultation questionnaires by providing multiple question choices and multiple forms of answer settings, as well as detailed statistical charts for results analysis. This paper introduces how to obtain the data of budget impact analysis based on Delphi method using Infopoll software, and analyzes the main results in detail.
