Spirometry is a pulmonary function test where correct interpretation of the results is crucial for accurate diagnosis of disease. There are online tools to assist in the interpretation of spirometry results; however, as yet none are validated. We evaluated the interpretation accuracy of the Espiro app using pulmonologist interpretations as the gold standard. This is an observational descriptive study in which 118 spirometry results were interpreted by the Espiro app, two pulmonologists, two primary care physicians, and two residents of a primary care training program. We determined the interpretation accuracy of the Espiro app and the concordance of the pattern and severity interpretation between the Espiro app and each of the observers using Cohen's kappa coefficient (). We obtained a sensitivity and specificity for the Espiro app of 97.5% (95% confidence interval (CI): 86.8-99.9%) and 94.9% (95%CI: 87.4-98.6%) with pulmonologist 1 and 100% (95%CI: 91.6-100%) and 98.7% (95%CI: 92.9-99.9%) with pulmonologist 2. The concordance for the pattern interpretation was greater than 0.907, representing almost perfect agreement. The concordance of the severity interpretation was greater than 0.807, representing substantial to almost perfect agreement. We concluded that the Espiro app is a valid tool for spirometry interpretation.
肺活量测定是一项肺功能测试，对测试结果的正确解读对于疾病的准确诊断至关重要。有一些在线工具可协助解读肺活量测定结果；然而，目前尚无经过验证的工具。我们以肺科医生的解读作为金标准，评估了Espiro应用程序的解读准确性。这是一项观察性描述性研究，其中118份肺活量测定结果由Espiro应用程序、两名肺科医生、两名初级保健医生以及一名初级保健培训项目的住院医师进行解读。我们使用科恩kappa系数（）确定了Espiro应用程序的解读准确性以及Espiro应用程序与每位观察者之间在模式和严重程度解读方面的一致性。对于Espiro应用程序，与第一位肺科医生相比，敏感性和特异性分别为97.5%（95%置信区间（CI）：86.8 - 99.9%）和94.9%（95%CI：87.4 - 98.6%）；与第二位肺科医生相比，敏感性和特异性分别为100%（95%CI：91.6 - 100%）和98.7%（95%CI：92.9 - 99.9%）。模式解读的一致性大于0.907，代表几乎完全一致。严重程度解读的一致性大于0.807，代表实质性到几乎完全一致。我们得出结论，Espiro应用程序是用于肺活量测定解读的有效工具。
