Observation on the effect of pre-operation micro-video education on improving the speed and quality control of pulmonary ventilation function examination for dust workers
操作前微视频宣教对提升粉尘作业人员肺通气功能检查速度及质量控制的效果观察

摘要

目的 探讨检查前微视频宣教对提升粉尘作业人员肺通气功能检查速度及质量控制的效果。方法 选取2024年01月—2024 年12月首次进行肺通气功能检测的1000名从事接触粉尘作业的工作人员为研究对象，并按照随机数字表法进行分组：对照组和试验组各500名。对照组实施肺通气功能检查的常规指导方法，试验组检查前先进行5分钟双语（普通话、粤语）微课视频进行讲解和指导，检查时再进行常规指导。所有检查结果，经不知分组的呼吸内科医生进行结果的判定，再由数据分析员按照分组情况进行统计分析，比较两组受检者肺通气功能检查完成的时间与完成的质量。结果 试验组在3分钟内完成检查的比率为 96.80%，显著高于对照组80.60%，差异有统计学意义（χ2=65.46 P < 0.01）。试验组A/B级质控达标率97.80%（A级87.20%），显著高于对照组85.00%（A级65.60%），差异有统计学意义（χ2=52.11 P < 0.01）。试验组肺通气功能完成质量等级（A-E级）与对照组对比，差异有统计学意义（Z=-8.39 P < 0.01）结论 检查前运用微视频教育，讲解肺通气功能检查过程中的注意事项和配合的方法，可缩短检查时间和提高检查效率，保障检查质量，值得推广。

Abstract

Objective To investigate the effectiveness of pre-examination micro-video education on improving the speed and quality of pulmonary function tests for workers exposed to dust.
Methods A total of 1,000 workers in dust-exposed occupations undergoing their first pulmonary function test between January 2024 and December 2024 were enrolled and randomly divided into two groups: a control group (500 participants) and an experimental group (500 participants). The control group received conventional pulmonary function test instruction, while the experimental group received a 5-minute bilingual (Mandarin and Cantonese) micro-video instruction before the test, followed by conventional instruction during the test. All test results were assessed by respiratory physicians who were unaware of the group assignments. Data analysts then performed statistical analysis based on group assignments. The time and quality of pulmonary function test completion were compared between the two groups.
Results The rate of completion within 3 minutes in the experimental group was 96.80%, significantly higher than the 80.60% in the control group (χ2 = 65.46, P < 0.01). The A/B quality control compliance rate in the experimental group was 97.80% (87.20% for Grade A), significantly higher than the control group's 85.00% (65.60% for Grade A), with a statistically significant difference (χ² = 52.11, P < 0.01). The difference in pulmonary ventilation function completion quality (grades A-E) between the experimental group and the control group was statistically significant (Z = -8.39, P < 0.01).
Conclusion   Using micro-videos to educate on precautions and cooperation during pulmonary ventilation function tests before the examination can shorten examination time, improve efficiency, and ensure quality, and is worthy of promotion.
