基于 PDCA 循环改进肿瘤专科医院术后统计方法

摘要

Objective To discuss the effect of PDCA circulation method on improving the statistical man -agement of postoperative pneumonia and the accuracy of statistics so that this index would accurately and effectively reflect postoperative complications.Methods Relative information of patients from January 2012 to June 2016 was collected using SQL Server 2000.The annual incidence of pneumonia after surgery was calculated using R Lan -guage.The statistical method of analyzing pneumonia after surgery was improved by PDCA circulation to determine the differences before and after the intervention .Results This study found and analyzed the following problems in the statistical analysis of postoperative pneumonia : some non -operative types of pneumonia were mistaken as post -operative pneumonia due to the diagnosis and coding problems , which led to statistical errors.The measures taken in the study reduced the error rate from 35.80% to 0.The difference of pre -intervention and post -intervention was statistically significant.Conclusion Statistical management of PDCA circulation in postoperative pneumonia significantly improves the result and the accuracy of statistical indicators .%目的：探讨 PDCA 循环法用于改进手术后肺炎统计管理的效果，以提高统计的准确性，使这项指标真实有效反映手术后并发症的发生情况。方法应用 SQL Server 2000收集2012年1月—2016年6月期间住院患者相关信息，利用 R语言工具统计每年手术后肺炎的发生率，采用 PDCA 循环改进手术后肺炎的统计方法，比较干预前后的差异。结果通过运用 PDCA 循环，查找分析手术后肺炎统计过程中的问题，发现某些非手术后肺炎的病例由于诊断填写及编码的问题，被误判为手术后肺炎，导致统计误差，通过采取改进措施，使误差率由35．80％下降为0，干预前后差异有统计学意义。结论PDCA 循环应用于手术后肺炎的统计管理，改进效果明显，提高手术后肺炎统计的准确性。
