个人数字助理在标本采集及运送中的应用

Effect of PDA on specimens＇ collection and transportation

目的评定个人数字助理（PDA）在标本采集及运送中的效果。方法采用盲指法将需行标本采集的住院患者，双日设为对照组，单日为试验组。对照组检验标本采集及运送使用传统方法，试验组在此基础上对检验标本采集及运送等关键环节使用PDA提示和执行。结果两组标本采集对象错误、标本送错、标本容器错误比较，对照组分别为2，5，12件，试验组分别为0，1，7件，差异无统计学意义（x2值分别为0．646，1．863，1．992，respectively；P〉0．05）；试验组标本送检不及时8件，标本丢失2件，标本采集量错误12件，均低于对照组（分别为39，10，30件），差异有统计学意义（x2值分别为25．071，4．993，10．266；P〈0．05）。结论PDA的使用对检验标本采集和运送的关键环节起到控制和记录作用，可促进并提高标本检验分析前的质量。

Objective To investigate the effect of PDA on specimens＇ collection and transportation. Methods Used the method of blind fingering line, hospitalized patients that needed be collected specimen were divided into control group and observation group by the odds day or double date. Traditional method was used on specimens＇ collection and transportation in control group, and observation group adopted PDA in the key links of specimens＇ collection and transportation. Results No significant difference was found in the number of errors of collection （0 vs 2）, loss of specimens （1 vs 5 ） and wrong containers （7 vs 12 ） between observation group and control group （ X2 = 0. 646,1. 863,1. 992 ; P 〉 0. 05 ）. The numbers of delivering for check not timely （ 8 vs 39）, loss of specimens（2 vs 10） and wrong volume of specimens（ 12 vs 30） in observation group were significantly lower than that in control group （ X2 = 25.071,4. 993,10.266, respectively; P 〈 0. 05 ）. Conclusions The use of PDA in the key links of specimens＇ collection and transportation play the role of control and recording, which can effectively control the pre-analysis quality of specimens.
