DEA模型应用于胸外科监护病房护理效率评价的研究

目的应用数据包络分析法（DEA）综合评价上海市12所三级甲等医院胸外ICU护理人力资源的效率，探讨效率低下的原因，为提高护理效率提供依据。方法采用整群抽样法选取上海市12所三级甲等医院，应用问卷调查法和工时测定法，采集胸外ICU护理单元的4项投入指标（护士人数、继续教育时间、培训时间、护理工时）和3项产出指标（平均住院日、年收治病人数、床位使用率），运用DEA进行分析研究。结果12个胸外ICU护理单元中，5个护理单元相对无效，无效的护理单元可以通过理想值的测算有目的地改善各指标值，使之达到相对有效。结论各三级甲等医院间胸外科ICU护理效率水平差异显著，而通过护理人力资源的合理配置可以实现效率最大化；建议采用DEA对护理效率进行评价分析。

Study of applying DEA Model to improving nursing efficiency of cardiothoracic surgical ICU

Objective To apply the method of Data envolop analysis(DEA) to evaluating the relative efficiency of cardiothoracic surgical ICU of 12 Grade Ⅲ-A hospital in Shanghai. Methods The input and output data of 12 cardiovascular surgical ICU were collected and analyzed by the way of questionnaires, work-hour measurement and data envelopment analysis(DEA). Results 5 of the 12 nursing units were inefficient. The inefficient nursing units could become relatively efficient by the improvement of all indexes. Conclusions The variation in nursing efficiency has been observed among 12 units. The optimization can be achieved through proper allocation of nursing resources. DEA should be applied to the analysis of nursing efficiency.
