目的 评价某三甲医院2018年各月及各科的校正后床位效率指数，分析其高效率或低效率运行的原因，并分析校正后床位效率指数的影响因素，为医院合理配置床位提供参考依据。方法 采用“归一法”计算某三甲医院2018年各月及各科的床位效率指数，用CD率进行校正；采用多元线性回归法分析校正后床位效率指数的影响因素。结果 2018年各月校正后床位效率指数中，7月最高（1.13），2月最低（0.58），除2月外其余月份效率指数均在0.9以上；各科校正后床位效率指数中，部分科室床位高效率运行的同时也有科室存在床位闲置的现象，重症医学科效率指数最高（4.06）；线性回归分析发现，期初人数、入院人数、2或3类切口手术人数越多，急诊入院率越高，校正后床位效率指数越大，床位效率越高；三四级手术例数越多，床位效率指数越低。结论 利用具体床位效率指数的影响因素，通过行政管理介入和医疗服务模式改善，可以有效实现医院床位的合理配置。

Objective To evaluate the bed efficiency index after correction of each month and each department of a tertiary hospital in 2018, to analyze the reasons for its high efficiency or low efficiency operation, and analyze the influencing factors of the adjusted bed efficiency index, so as to provide reference for the rational allocation of beds in the hospital. Methods The "normalization method" was adopted to calculate the bed efficiency index of each month and each department of a tertiary hospital in 2018, and the CD rate was used for correction.Multiple linear regression method was used to analyze the influencing factors of bed efficiency index after correction. Results For the beds efficiency index in every month, the highest was in July and the lowest was in February.Indexes in every month except that in February were all higher than 0.9.In the adjusted bed efficiency index of all departments, while some department beds were running with high efficiency, there were also some departments with vacant beds. The efficiency index of ICU was the highest (4.06). The linear regression analysis found that the higher the initial number of patients, the number of patients admitted, and the number of patients undergoing two or three types of incision surgery, the higher the emergency admission rate, the higher the bed efficiency index after correction, and the higher the bed efficiency. The more cases of grade 3 and 4 operations, the lower the bed efficiency index. Conclusion Reasonable allocation of hospital beds could be carried out efficiently through administrative intervention and the improvement of medical service mode, and through making use of affecting factors of bed efficiency index.
