理由和目标。本研究的目的是统计学上确定一些明确的领带，明确）胸部X线摄影报告的情况下，急性细菌性肺炎的特点。材料和方法。七位医生分别阅读了292份胸部X线检查报告，以确定它们是否包含肺炎的放射学证据。非肺炎报告被定义为医生一致分类为支持或不支持肺炎诊断的报告。模棱两可的报告根据他们在医生中引起的分歧程度被分配了模糊程度。文献中描述的明确报告的特征被手动量化并分配给每个报告。为了识别统计上区分明确报告和模糊报告的特征，作者进行了有序逻辑回归分析，其中因变量是报告收到的反对票的数量，自变量是报告的量化特征。六个独立变量与明确的报告在统计学上显着相关（P < .05）。其中三个是正相关的：在具有肺炎相关观察结果、短句和肺炎相关观察结果冗余的报告中，对结果是否支持肺炎诊断的解释。三个是负相关的：对肺炎相关观察结果使用不确定性修饰语的比例较高，仅使用描述性术语描述肺炎相关观察结果，以及肺炎相关信息量不足。明确的胸部X线片报告最有影响力的特征是，当结果可能具有指示性时，对X线片是否支持肺炎诊断的解释。
Rationale and Objectives. The purpose of this study was to statistically identify some characteristics of unambiguous tie, clear) chest radiography reports in the context of acute bacterial pneumonia.Materials and Methods. Seven physicians individually read 292 chest radiography reports to determine if they contained radiologic evidence of pneumonia. Unambiguous reports were defined as those that physicians unanimously classified as supporting or not supporting the diagnosis of pneumonia. Ambiguous reports were assigned degrees of ambiguity on the basis of how much disagreement they caused among the physicians. Characteristics of unambiguous reports as described in the literature were manually quantified and assigned to every report, To identify characteristics that statistically distinguished unambiguous from ambiguous reports, the authors performed an ordinal logistic regression analysis for which the dependent variable was the number of dissenting votes the report received and the independent variables were the quantified characteristics of the report.Results. Six independent variables were statistically significantly associated with unambiguous reports (P < .05). Three were positively associated: an interpretation of whether findings supported the diagnosis of pneumonia in reports with pneumonia-related observations, short sentences, and redundancy of pneumonia-related observations. Three were negatively associated: high use of uncertainty modifiers for pneumonia-related observations, use of only descriptive terms to describe pneumonia-related observations, and insufficient amount of pneumonia-related information.Conclusion. The most influential characteristic of an unambiguous chest radiography report was an interpretation of whether the radiograph supported the diagnosis of pneumonia when findings could be indicative.
