APACHEⅡ评分变化率与ICU危重病患者预后相关性研究

A correlation analysis of the change rate of APACHE Ⅱ scores and the prognosis in severe ill ICU patients

目的 研究APACHEⅡ评分变化率与ICU危重病患者预后的相关性.方法 将2012-01～05收住本院ICU的危重病例145例,按APACHEⅡ评分变化率分成两组,比较APACHEⅡ评分1、APACHEⅡ评分2、APACHEⅡ评分变化率、死亡率的差异,对APACHEⅡ评分变化率和APACHEⅡ评分1进行相关性分析.结果 两组患者性别、年龄、APACHEⅡ评分1 和APACHEⅡ评分2比较差异无统计学意义（P〉0.05）.两组APACHEⅡ评分变化率差异有统计学意义（P〈0.05）.两组死亡率差异有统计学意义（P〈0.01）.APACHEⅡ评分变化率与APACHEⅡ评分1无明显相关性（P〉0.05）.结论 APACHEⅡ评分变化率能更早期、更准确地预测预后.

Objective To investigate the correlation of the change rate of APACHE Ⅱ scores and the prognosis in severe ill patients of ICU. Methods From January to May 2012, 145 severe ill patients in our ICU were divided into two groups according to the change rate of APACHE Ⅱ scores. APACHE Ⅱ scores on day 1 and day 2 of admission, the change rate of APACHE II scores, and the death rate were compared. The correlation between the change rate of APACHE Ⅱ scores and APACHE Ⅱ scores on day 1 of admission was analyzed. Results Patients age and gender showed no significant differences （ P 〉 0.05 ）, so did the APACHE Ⅱ scores on day 1, day 2 of admission （ P 〉 0.05 ）. There were significant differences on the change rate of APACHE Ⅱ scores between the two groups （P 〈 0.05）. There were very significant differences on mortality between the two groups （P 〈 0.01 ）. There were no significant correlation between the change rate of APACHE Ⅱ scores and APACHE Ⅱ scores on day 1 of admission （ r = - 0.114, P 〉 0.05 ）. Conclusion The change rate of APACHE Ⅱ scores can predict the prognosis more accurate and earlier.
