Determining factors affecting the acceptability of spirometry: A survey study
in a tertiary chest diseases center
Introduction
Unlike other laboratory tests, spirometry requires the participant’s
full compliance with the maneuvers in the test for an acceptable test
result. In this study, we aimed to determine the suitability of spirometric tests
regarding acceptability and the factors associated with acceptability.
Materials and Methods
Before the test, our 15-scale questionnaire, prepared
by us in the respiratory function laboratory, was applied to the participants
who requested spirometric examination in our hospital. Afterwards, patients
were subjected to spirometric analysis. Spirogram results of the participants
were evaluated by four clinicians who were experts in the field based on the
acceptability criteria in the American Thoracic Society and European
Respiratory Society Spirometry Standardization Guidelines. Participants were
divided into two groups as those who met the acceptability criteria and those
who did not. Both groups were compared regarding demographic data,
comorbidities, education levels, and questions in the questionnaire.
Results
The acceptability spirometry rate was 71.2%. The most common
error among those who could not perform an acceptable test was the inability
to complete the expiratory time to the time that would create a plateau,
with 37.3%. Education level and acceptability of spirometry were not related
(p= 0.228). Asthma was statistically significantly higher in the group that
performed acceptable spirometry (p= 0.049). Acceptable spirometry rate was
statistically significantly higher in the participants who had previously
performed spirometric tests compared to the other group (p< 0.001). The test
success of the participants who did not have success anxiety about the test
was significantly higher than the other group (p= 0.033).
Conclusion
Reduction of participants’ anxiety and repetitive testing increases
test acceptability. For this reason, in our clinical practice, we recommend that
people who want a spirometry test relieve their anxiety about the test and
repeat the test in unacceptable tests.
