目的 通过应用数据包络分析（DEA）方法对医院科室运营效率进行评价，分析DEA方法在医院临床科室相对效率评价中的价值。 方法 采用聚类分析等确定投入产出指标，采用DEA方法中C2R和BC2模型对2004年1月－2008年12月各科室相对效率进行评价和分析。 结果 70个被评价单元中有41个被评价单元的总体有效值为1，属于相对有效单元；29个被评价单元的C2R模型总体有效值＜1，属于相对无效单元。 结论 DEA方法适用临床科室相对效率评价多投入、多产出的特点，能够有效识别被评价单位中的无效单元，并且对于投入产出值能够指明导致无效的方向和需调整的程度，指导相关管理部门对科室的调整和资源投入方向。
This paper compares emergency medical rescue experience of West China Hospital of Sichuan University in the latest three earthquakes occurred in western Sichuan, and mainly introduces the experience in organization and coordination, rescue speed, treatment of the injured, and rescue characteristics in Jiuzhaigou earthquake, which can provide reference for future earthquake emergency medical rescue.
Co-infection with severe influenza and bacterial is well known, but in recent years, more and more studies report that aspergillus have been identified as important pathogens, secondary only to bacteria in severe influenza. Influenza-associated aspergillus (IAA) brings a high death rate and heavy burden to our country. Therefore, early diagnosis and effective treatment are needed. In order to better understand IAA, this review summarizes the available literature on the association of IAA, including epidemiology, diagnosis and treatment.
Objective To discuss the clinical value of whole spine magnetic resonance imaging (WSMRI) in practice of neurosurgical spinal surgery. Method A total of 70 cases examined using WSMRI between January 2015 and December 2016 were collected and analyzed retrospectively. Results All patients got clear images of WSMRI. Eighteen cases got important information, including spinal variation (1 case), multiple lesions (3 cases), combined lesions (6 cases) and large range multi-segmental lesions (8 cases), which were missed by single-segment MRI . Conclusions WSMRI can show all the spine, spinal cord and surrounding tissue in one image at one time. It has high clinical value because of its accurate positioning, comprehensiveness, time saving, and low rate of misdiagnosis and missed diagnosis.
