The spirometry test is a valuable test to evaluate the performance of the respiratory system. The interpretation of the results is highly dependent on the quality of its performance, while the inappropriate quality results in unwanted consequences for individuals and the healthcare system. This study investigated the quality of spirometry tests performed in occupational health.
In this cross-sectional study, the quality of 776 spirometry tests in different occupational centers by the specialists in Rasht, Iran, in 2020, based on the guidelines of the American Thoracic Society (ATS), was investigated. The quality and success rate of the test and the demographical characteristics of the operators and the participants were collected. All data was analyzed using SPSS software version 20.
Out of 776 spirometry tests, about 69.7% were unacceptable. Among the unacceptable tests, a pause error between inhalation and exhalation was identified in 7.4% of tests. Additionally, 4.6% of the unacceptable tests exhibited a cough error within the first second, while an exhalation error of less than six was observed in 85%. Repeatability errors were found in 60.9% of the tests. Furthermore, among some errors, the communication error between the characteristics of the technicians and the test performance errors were evident.
According to the results, most of the performed tests were unacceptable with no repeatability, which indicated that the validity and quality of spirometry tests and their interpretation were inappropriate in the field of occupational health in Rasht, Iran.
肺量测定是评估呼吸系统功能的一项有价值的测试。结果的解释高度依赖于其性能的质量，而不当的质量会给个人和医疗保健系统带来不必要的后果。本研究调查了在职业健康中进行的肺量测定测试的质量。
在这项横断面研究中，调查了 2020 年伊朗拉什特的专家在不同职业中心进行的 776 次肺量测定测试的质量，这些测试是基于美国胸科学会（ATS）的指南进行的。收集了测试的质量和成功率以及操作人员和参与者的人口统计学特征。所有数据均使用 SPSS 软件版本 20 进行分析。
在 776 次肺量测定测试中，约 69.7%是不可接受的。在不可接受的测试中，7.4%的测试存在吸气和呼气之间的暂停错误。此外，4.6%的不可接受测试在第一秒内出现咳嗽错误，而 85%的测试呼气时间小于 6 秒。在 60.9%的测试中发现了重复性错误。此外，在一些错误中，技术人员特征之间的沟通错误和测试性能错误是明显的。
根据结果，大多数进行的测试都是不可接受的，没有重复性，这表明在伊朗拉什特的职业健康领域，肺量测定测试及其解释的有效性和质量是不适当的。
