“…Different questionnaires have been developed for COPD case finding in primary care based on variables associated with increased or decreased risk of COPD . Recently, Stanley et al ., using the COPD Diagnostic Questionnaire, found that it did not perform well in identifying people with COPD when compared with spirometry.…”

“…However, extrapolation of the results to 1 year suggests that opportunistic approaches may be more efficient. Several studies have looked at developing screening tools to select persons at risk for further spirometric investigation . The simpler and more accurate the screening tool, the more useful for identifying patients for spirometry diagnosis.…”

Background and objective: Opportunistic chronic obstructive pulmonary disease (COPD) case finding approaches for high-risk individuals with or without symptoms is a feasible option for disease identification. PUMA is an opportunistic case finding study conducted in primary care setting of Argentina, Colombia, Venezuela and Uruguay. The objectives were to measure COPD prevalence in an at-risk population visiting primary care for any reason, to assess the yield of this opportunistic approach and the accuracy of a score developed to detect COPD. Methods: Subjects attending routine primary care visits, ≥40 years of age, current or former smokers or exposed to biomass smoke, completed a questionnaire and performed spirometry. COPD was defined as post-bronchodilator (post-BD) forced expiratory volume in 1 s (FEV 1 )/forced vital capacity (FVC) < 0.70 and the lower limit of normal of FEV 1 /FVC. Results: A total of 1743 subjects completed the interview; 1540 performed acceptable spirometry. COPD prevalence was 20.1% (n = 309; ranging from 11.0% in Venezuela to 29.6% in Argentina) when defined using post-BD FEV 1 /FVC < 0.70, and 14.7% (n = 226; ranging from 8.3% in Venezuela to 21.8% in Colombia) using the lower limit of normal. Logistic regression analysis for both definitions showed that the risk of COPD was significantly higher for persons >50 years, heavy smokers (>30 pack-years), with dyspnoea, and having prior spirometry. A simple score and a weighted score constructed using the following predictive factors: gender, age, pack-years smoking, dyspnoea, sputum, cough and spirometry, had a mean accuracy for detecting COPD (post-BD FEV 1 /FVC < 0.70) of 76% and 79% for the simple and weighted scores, respectively. Conclusion: This simple seven-item score is an accurate screening tool to select subjects for spirometry in primary care.

“…Formal questionnaires designed to improve the efficiency and accuracy of a COPD diagnosis have been shown to perform well when used to select patients for diagnostic spirometry. 17 The COPD Diagnostic Questionnaire, 18 the Lung Function Questionnaire, 19 and the COPD Assessment Test 20 are 3 examples in which specific cut points (based on questionnaire score) identified patients whose subsequent spirometry confirmed a diagnosis of COPD. Some patients have symptoms that result in questionnaire scores consistent with COPD, although their spi-rometry values are above the usual thresholds for airway obstruction.…”

Office Spirometry in Primary Care for the Diagnosis and Management of COPD: National Lung Health Education Program Update

et al. 2018

View full text Add to dashboard Cite

The use of office spirometry was recommended by the National Lung Health Education Program (NLHEP) consensus conference in 1999 for detection and management of COPD. Since that time, spirometry utilization has increased, but its role in the diagnosis of COPD is still evolving. This update reviews the role of spirometry for screening and case finding in COPD as well as for asthma. Spirometry has been used for disease management in patients with airway obstruction, with varying results. The diagnostic criteria for COPD using spirometry have also evolved in the past 17 years, with differences arising between the Global Initiative for Chronic Obstructive Lung Disease and NLHEP recommendations. More sophisticated spirometers as well as new reference equations are widely available. Standardization guidelines from the American Thoracic Society/European Respiratory Society published in 2005 provide a robust framework for performing and interpreting spirometry, but clinicians still need hands-on training and meaningful feedback to perform high-quality spirometry in the office setting.

“…Entre estos dispositivos cabe destacar a aquellos con capacidad para la medición del cociente FEV 1 /FEV 6 , por ser éste el parámetro clave para el diagnóstico de EPOC. Estos dispositivos simplifican el procedimiento para la obtención del cociente FEV 1 /FEV 6 respecto a la espirometría forzada convencional y pueden contribuir a la reducción de la variabilidad entre centros de salud respecto a la disponibilidad de pruebas para el diagnóstico de EPOC 138 .…”

“…Esta recuperación fue menor en los pacientes que no dejaron de fumar hasta que la enfermedad había progresado hasta un nivel de mayor de gravedad. Estos datos sugieren que los pacientes con EPOC pueden modificar la progresión de la enfermedad dejando de fumar, y los máximos efectos se observan cuando la intervención se produce en una fase precoz136 .Por lo expuesto anteriormente, una de las consecuencias del infradiagnóstico es el retraso en la intervención sobre los factores de riesgo, principalmente el consumo de tabaco138 . Para realizar la intervención sobre los factores de riesgo existen distintos niveles.…”
