This paper describes the development of regional hospital input price indexes that is consistent with the general methodology used for the National Hospital Input Price Index. The feasibility of developing regional indexes was investigated because individuals inquired whether different regions experienced different rates of increase in hospital input prices. The regional indexes incorporate variations in cost-share weights (the amount an expense category contributes to total spending) associated with hospital type and location, and variations in the rate of input price increases for various regions. We found that between 1972 and 1979 none of the regional price indexes increased at average annual rates significantly different from the national rate. For the more recent period 1977 through 1979, the increase in one Census Region was significantly below the national rate. Further analyses indicated that variations in cost-share weights for various types of hospitals produced no substantial variations in the regional price indexes relative to the national index. We consider these findings preliminary because of limitations in the availability of current, relevant, and reliable data, especially for local area wage rate increases.
本文描述了与用于编制国家医院投入价格指数的一般方法相一致的地区医院投入价格指数的编制情况。研究编制地区指数的可行性是因为有人询问不同地区医院投入价格的上涨率是否不同。地区指数纳入了与医院类型和位置相关的成本分担权重（某一费用类别在总支出中所占的份额）的差异，以及不同地区投入价格上涨率的差异。我们发现，在1972年至1979年期间，没有一个地区价格指数的年均增长率与全国增长率有显著差异。在1977年至1979年这一较近时期，一个普查地区的增长率明显低于全国增长率。进一步分析表明，各类医院成本分担权重的差异相对于全国指数而言，并未在地区价格指数中产生实质性差异。由于当前、相关和可靠数据的可得性存在局限性，尤其是关于当地工资率增长的数据，我们认为这些发现是初步的。
