The national community hospital input price index presented here isolates the effects of prices of goods and services required to produce hospital care and measures the average percent change in prices for a fixed market basket of hospital inputs. Using the methodology described in this article, weights for various expenditure categories were estimated and proxy price variables associated with each were selected. The index is calculated for the historical period 1970 through 1978 and forecast for 1979 through 1981. During the historical period, the input price index increased an average of 8.0 percent a year, compared with an average rate of increase of 6.6 percent for overall consumer prices. For the period 1979 through 1981, the average annual increase is forecast at between 8.5 and 9.0 per cent. Using the index to deflate growth in expenses, the level of real growth in expenditures per inpatient day (net service intensity growth) averaged 4.5 percent per year with considerable annual variation related to government and hospital industry policies.
这里呈现的国家社区医院投入价格指数，分离了生产医院护理所需商品和服务价格的影响，并衡量了固定市场篮子医院投入价格的平均百分比变化。采用本文所述方法，估算了各类支出类别的权重，并为每个类别选择了相关的替代价格变量。该指数是针对1970年至1978年的历史时期计算的，并对1979年至1981年进行了预测。在历史时期内，投入价格指数平均每年增长8.0%，而总体消费者价格的平均增长率为6.6%。对于1979年至1981年期间，预计年平均增长率在8.5%至9.0%之间。使用该指数对费用增长进行平减，每位住院患者每天支出的实际增长水平（净服务强度增长）平均每年为4.5%，且每年存在与政府和医院行业政策相关的显著差异。
