    摘要:

    摘要:目的 评估和优化血气分析的审核规则,提高自动审核通过率。方法 回顾分析 8 453 份血气标本的自动审核通过率。 参考 CLSI AUTO15、CLSI EP33,评估和优化血气项目的限值和差值范围。调整规则并通过验证后,重新计算自动审核通过 率。结果 血气分析的自动审核原有规则 15 个项目共 64 条,自动审核通过率是 46.4%。不通过原因差值占 22.5%,限值占 22.3%。调整差值规则 6 条,如氧分压差值百分率从“<-130%或>130%”调整为“<-180.6%或>234.3%”。调整限值规则 8 条,如警戒总氧含量从“<2.5 mmol / L 或>20.4 mmol / L”调整为“<4.1 mmol / L 或>23.4 mmol / L”。928 例验证人工审核和自动 审核的符合率 100%。规则调整后自动审核通过率是 66.2%。结论 合理地调整限值和差值范围可提高自动审核的通过率。

    Abstract:Objective To evaluate and optimize the autoverification rules for blood gas analysis so as to improve the pass rate of auto verification. Methods The passing rates of 8 453 blood gas samples in autoverification (AV)were retrospectively analyzed. The limits and of blood gas items were evaluated and optimized by referring to CLSI AUTO15 and CLSI EP33. After adjusting the rules,the pass ing rates of autoverification were recalculated. Results There were 64 rules in 15 items in the original autoverification rules for blood gas analysis. The passing rate of autoverification was only 46.4%. The delta check accounted for 22.5% and the limit value accounted for 22.3% in the failed reasons. Six delta check rules were adjusted,for example,the percentage of delta check for oxygen partial pres sure was changed from " <-130 or >130%" to " <-180.6% or >234.3%" . Eight limit rules were adjusted,for example,the alert of to tal oxygen concentration was changed from " <2.5 mmol / L or >20.4 mmol / L" to " <4.1 mmol / L or >23.4 mmol / L" . The agreement rate of manual audit with autoverification was 100% in 928 cases. The passing rate of autoverification was 66.2% after the rule adjust ment. Conclusion Reasonably adjusting the limits value and delta check range may improve the passing rate of autoverification.
