疑难危重率对平均住院日影响分析

Analysis of Influence on Mean In-hospital Day by Ratio of Severity

目的 :分析疑难危重率对平均住院日的影响程度。方法 :收集某三级甲等医院 2 0 0 3年 1月 1日至 2 0 0 3年 12月 31日所有出院病案 330 98份 ,采用 SAS6 .12 ,进行统计分析与评价。结果与结论 :疑难危重率与平均住院日呈直线关系 ,解决了医疗单位之间平均住院日缺乏可比性的问题 ,从而为合理评价平均住院日提供了一种可借鉴的新模式。

Objective: Analyze the degree of impact of mean in-hospital day by ratio of severity. Methods: Collect 33098 case histories from Jan 1st, 2003 to Dec 31st, 2003. Analyze and evaluate data with SAS 6.12. Results and Conclusions: The ratio of severity is liner to mean in-hospital day. It solved problem that each hospital is incomparable by mean in-hospital day, and gave new mode to evaluating mean in-hospital day reasonably.
