In this article, the authors estimate a multiple-output cost function for a sample of 2,235 hospitals during the period 1984-88 to disaggregate total costs into inpatient and outpatient components. The results suggest that outpatient cost growth is roughly proportional to that of inpatient cost, despite much higher relative growth in revenues and utilization on the outpatient side. The stability in the outpatient/inpatient cost ratio implies that the increase in the outpatient-to-inpatient utilization ratio was offset by a decline in their relative unit costs.
在本文中,作者估算了1984年至1988年期间2235家医院样本的多产出成本函数,以将总成本分解为住院和门诊部分。结果表明,尽管门诊收入和利用率的相对增长要高得多,但门诊成本增长与住院成本增长大致成比例。门诊/住院成本比率的稳定性意味着门诊与住院利用率比率的上升被其相对单位成本的下降所抵消。
