  • Title: Pulmonary function test quality in the elderly: a comparison with younger adults.
    Author: Haynes JM.
    Journal: Respir Care; 2014 Jan; 59(1):16-21. PubMed ID: 23801784.
    Abstract:
    BACKGROUND: Elderly patients may be at greater risk for misdiagnosis and inappropriate treatment as a consequence of pulmonary function test underutilization and tests being conducted with low quality expectations. This study sought to determine if elderly patients are able to achieve both spirometry and diffusion capacity (DLCO) quality scores comparable to a younger adult population. METHODS: This was a retrospective review of pulmonary function data over a 22 month period. A list of every subject age ≥ 80 years (elderly group) and ages 40-50 years (control group) tested during the time period was compiled. The quality of spirometry and DLCO testing were examined. RESULTS: Overall, 92.6% (139/150) of the elderly group and 91.5% (163/178) of the control group spirometry tests satisfied all American Thoracic Society/European Respiratory Society acceptability and reproducibility criteria (P = .84), and 84.9% (96/113) of the elderly group and 88.5% (108/122) of the control group DLCO tests satisfied all the acceptability and reproducibility criteria (P = .45). CONCLUSIONS: Elderly patients referred to a hospital-based pulmonary function test lab can be expected to achieve spirometry and DLCO quality scores comparable to younger adult patients.
