肾小球滤过率测算公式的计算机智能系统应用于临床的价值

Clinical value of the computer intelligent system of the measure formula for glomerular filtration rate

目的探讨肾小球滤过率(GFR)测算公式的计算机智能系统(临床应用价值。方法CIS)依次运用10条公式,分别采取3种方法(手工计算、计算器运算、CIS测算)计算出30例慢性肾脏病患者的CCr/e GFR,比较3种方法的计算耗时、错误率和得票数。结果 CIS耗时显著少于计算器耗时(P<0.01),计算器耗时显著少于手算耗时(P<0.01);CIS错误率显著低于计算器错误率(P<0.01),计算器错误率显著低于手算错误率(P<0.01)。CIS甚至获得12票(全票),显著高于其他两种方法(P<0.01)。结论用CIS测算CCr/GFR使用方便,耗时少且准确率高,值得临床推广。

Objective To investigate the clinical value of the computer intelligent system（CIS）of the measure formula for glomerular filtration rate（GFR）.Methods The CCr/e GFR of 30 patients with chronic kidney diseases（CKD）was calculated with three methods（manual calculation,calculator and CIS measure）and by successively using 10 formulas.The time consumption of the calculation,error rate and the number of votes of the three methods were compared.Results The time consumption of CIS was significantly less than that of calculator（P〈0.01）,and the time consumption of calculator was significantly less than that of manual calculation（P〈0.01）;the error rate of CIS was significantly lower than that of calculator（P〈0.01）,and the error rate of calculator was significantly lower than that of manual calculation（P〈0.01）.CIS even won all the 12 votes,significantly higher than the other two methods（P〈0.01）.Conclusion The CIS can be easily applied in the measure of CCr/GFR,consume less time and has a high accuracy,which is worth clinical promotion.
