价格波动度在评价中加两国片剂分剂量节省成本中的应用

Application of Price Ratio to Evaluate Cost Saving of Tablets Splitting in China and Canada

目的:评价中、加两国高剂量规格片剂分剂量是否节省成本。方法:通过统计文献资料中片剂的价格,计算价格波动度的大小及其分布、节省比例。结果:中、加两国临床常用的多种规格的片剂,其价格波动度(SP)均小于1。SP范围分别为0.13～0.83、0.00～0.99,节省比例范围分别为8.6%～43.7%、0.3%～50.0%。加拿大SP分布在0～0.33范围的比例更多,两国比较有显著性差异(P<0.05)。结论:与应用低剂量规格比较,中、加两国高剂量规格片剂分剂量服用时均能节省成本,但加拿大节省的成本更多。

OBJECTIVE： To evaluate whether higher strength tablets have cost-saving potential in China and in Canada. METHODS： Adopting tablets price published in the literature, steepness of pricing （SP）, its distribution and cost-saving percentage was calculated. RESULTS： SP was 0.13～0.83 in China,0.00～0.99 in Canada, cost-saving percentage was 8.6%～43.7% in China、0.3%～50.0% in Canada respectively. There was significant difference in the distribution of SP between 0～0.33 in Canada（P0.05）. CONCLUSION： Compared to the lower strength tablets, the higher strength tablets can reduce cost when split in China and Canada, but the later can achieve more cost savings.
