编码差异对手术后肺炎评价指标影响

目的：探讨手术后肺炎的正确编码方法及统计方法，提高统计的准确性，使医院质量考核指标符合国家标准。方法应用SQL Server 2000收集2012—2014年住院患者相关信息，利用R语言工具，分别通过诊断名称和编码进行搜索，统计每年手术后肺炎的发生率。结果通过诊断名称和编码搜索结果相差较大，编码搜索的手术后肺炎发生率高。深入比较分析，发现存在某些诊断如炎性结节、炎性假瘤等误编码为肺炎的现象，提出相应的改进措施。结论手术后肺炎的统计中应注意一些特殊诊断的编码问题，以免发生误判而导致指标不准确。

Effect of Different Statistical Methods on Evaluation Index of Postoperative Pneumonia

Objective To explore the correct coding method and statistical method of postoperative pneumo -nia, improve the accuracy of statistics so that the hospital quality assessment indexes could meet national standards . Methods This study used SQL Server 2000 to collect relative information of patients from 2012 to 2014, carried on the search by diagnosing name and code separately to calculate the incidence of postoperative pneumonia every year . Results The search result by diagnostic name and code was quite different .The incidence of postoperative pneumo-nia by diagnostic code was much higher than by diagnostic name .Some diagnosis such as pulmonary inflammatory nodule and pulmonary inflammatory pseudotumor were inaccurately coded as pneumonia .In this paper , we propose corresponding improvement methods .Conclusion When analyzing the statistics of postoperative pneumonia , we should pay attention to the special diagnosis of coding problems to avoid inaccurate indicators from misdiagnosis .
