Walters et al.,
2011,
Australia
To evaluate the diagnostic errors of
COPD in primary units
Spirometry
Cross-
sectional
1,200; Not
informed; 65
31
Of the 1,200 patients identified, 341 (58%)
underwent spirometry and 234 (69%) had a
confirmed diagnosis. In 31% of cases, diagnostic
errors were found

Hamers et al.,
2006, Brazil
To assess the competence of GPs in
primary care regarding the diagnosis
of COPD
Spirometry
Cross-
sectional
350; ≥ 15 years;
46.8
34
Of the 142 (44.9%) patients who underwent
spirometry, 94 (66%) had been correctly diagnosed
by the GPs (Kappa = 0:55), nine with confirmed
COPD and 85 without COPD. The remaining 48
(34%) were discordant: 27 had COPD according to
the spirometry and were not diagnosed by the GPs,
and 21 were false positives

Joo et al.,
2011, United
States
To examine the characteristics
associated with the use of
spirometry in primary care with
increased risk for COPD and to
determine the diagnostic accuracy
of spirometry in patients with COPD
Spirometry
Cohort
1,052;≥ 35;57
Not informed
A total of 1,052 patients were identified and 527
(50%) had spirometry. Of the 159 patients
identified as COPD, 93 (58.5%) met the GOLD
criteria.

Of the 362 without a diagnosis of COPD,
93 (25.7%) had COPD according to the same
criteria. It was also found that chronic cough or
dyspnea were more associated with a request for
spirometry than current or previous smoking habits

smoking history

Cross-

1,459; ≥40; 60

Of the 1,459 eligible patients, 1,003 underwent
spirometry and completed a questionnaire. Of
these, 208 (20.7%) had spirometric criteria for
COPD according to GOLD
