目的研究住院平均费用两种算法的实际含义,对其差异进行分析。方法采用对比分析及相关分析,阐述两种算法的实际含义,探讨其差异的原因。结果对于月度等短期数据,两种算法所得结果有较大差异,而年度数据的差异较小。结论应选择以出院病人总费用计算住院平均费用的算法。 Objective To study the meanings of the two methods of hospitalization average cost and analyze the differences. Methods The comparative analysis and correlation analysis are used to explain the actual meaning of the two algorithms and to explore the reasons for the differences. Results For the monthly and other short-term data, the results obtained by the two algorithms are quite different, but the difference of the annual data is small. Conclusion The algorithm to calculate the average cost of hospitalization should be selected based on the total cost of discharged patients.
