The aim of the study was to measure technical and scale efficiency of public health centers in three districts of Jimma zone, Ethiopia. A two-stage data envelopment analysis was used. First, we estimated technical and scale efficiency of the health centers. In the second stage, institutional and environmental factors were against technical efficiency of the health centers to identify factors associated to efficiency of the health centers.
Eight out of the 16 health centers in the study were found to be technically efficient, with an average score of 90% (standard deviation = 17%). This indicates that on average they could have reduce their utilization of all inputs by about 10% without reducing output. On the other hand, 8 out of 16 health centers were found to be scale efficient, with an average scale efficiency score of 94% (standard deviation = 9%). The inefficient health centers had an average scale score of 89%; implying there is potential for increasing total outputs by about 11% using the existing capacity/size. Catchment population and number of clinical staff were found to be directly associated with efficiency, while the number of nonclinical staff was found to be inversely associated with efficiency.
本研究旨在衡量埃塞俄比亚吉马地区三个区公共卫生中心的技术效率和规模效率。采用两阶段数据包络分析。首先，我们估计了卫生中心的技术效率和规模效率。在第二阶段，将机构和环境因素与卫生中心的技术效率进行对比，以确定与卫生中心效率相关的因素。
研究中的16个卫生中心中有8个在技术上是有效的，平均得分为90%（标准差 = 17%）。这表明，平均而言，它们可以在不减少产出的情况下将所有投入的利用率降低约10%。另一方面，16个卫生中心中有8个在规模上是有效的，平均规模效率得分为94%（标准差 = 9%）。效率低下的卫生中心平均规模得分为89%；这意味着利用现有能力/规模，总产出有增加约11%的潜力。发现集水区人口和临床工作人员数量与效率直接相关，而非临床工作人员数量与效率呈负相关。
