生理参数差计分法的意义和临床应用

The significance and clinical application of the physiological parameter difference score

目的：通过自行研究的生理参数差计分法对危重患者病情严重程度进行评估，探讨本方法的可行性。方法：根据反映疾病严重程度的准确性、灵敏性、易测程度，筛选出21个计分指标，各指标超过正常的数值再乘以系数即得该项的小计分，诸小计分之和即为疾病严重度的总计分。结果：经5所医院316例病例严重度测试，平均计分125．4分，重症加危重症患者占92．08％，＞90分为界限，＞90分者病死率为81．03％。计分越高，病情越严重，病死率越高。结论：本方法简明，运算方便，指标多，信息覆盖面广，准确性强。经与APACHEⅡ同组验证，同步性强，具有可信性、可比性和可行性。

Objective:To study the feasibility of the physiological parameter difference score in assessment of seventy in critical patients. Methods: According to the accuracy,sensibility and simplification,we elected 21 physiological parameters as score indexes. The difference between each measured parameter and baseline value times its coefficient was a single score. The sum of all the single scores wasdefined as the general seventy score of the disease. Results:Score assessments were made in 316 casesfrom 5 hospitals, in whom 92. 08% were critical patients, and the average score was 125. 4. Taking 90points as a cutoff point,the mortality was 8l. 03 % when the score exceeded such a value. The higher thescore,the more serious was the disease,hence the higher the mortality. Conclusions:Our method is simple,convenient,accurate and easy to popularize,and the results simulates closely to APACHE n in clinical trials.
