“…Primary analyses from the CAPTURE and COPD-Q questionnaires have been reported previously. 23 The present analysis reports the prevalence of spirometry-based airflow limitation and PRISm among all study participants (primary endpoint). The characteristics of participants with airflow limitation, with PRISm, and without airflow limitation or PRISm, and the characteristics of never smokers, past smokers, and current smokers are reported as secondary endpoints.…”

“…Full details of sample size calculations have been reported previously. 23 The following were conducted as post-hoc analyses: the association between history of childhood asthma and PRISm was evaluated using the Chi-square test. Statistical differences between patients with airflow limitation, with PRISm, and without airflow limitation or PRISm for BMI values were evaluated by ANOVA Tukey’s test.…”

Purpose Many individuals with obstructive airway disease (OAD), including chronic obstructive pulmonary disease (COPD) and asthma, remain undiagnosed, despite the potential for reducing disease burden through early detection and treatment. OCEAN aimed to determine the prevalence of, and characteristics associated with, impaired lung function in a Japanese population, with the goal of improving strategies for early OAD detection. Methods OCEAN was an observational, cross-sectional study in sequentially recruited Japanese individuals ≥40 years of age undergoing routine health examinations. Participants completed screening questionnaires and spirometry testing. Airflow limitation was defined as forced expiratory volume in 1 second/forced vital capacity (FEV 1 /FVC) <0.7 by pre-bronchodilator spirometry. Preserved ratio impaired spirometry (PRISm) was defined as FEV 1 /FVC ≥0.7 and FEV 1 <80% predicted. The primary endpoint was prevalence of spirometry-based airflow limitation and PRISm. The characteristics of study participants were reported as secondary endpoints. Results Overall, 2518 individuals were included; 79% were <60 years of age (mean 52.0 years). Airflow limitation and PRISm were observed in 52 (2.1%) and 420 (16.7%) participants, respectively. FEV 1 in the PRISm group was between that in the no airflow limitation/PRISm and airflow limitation groups, FVC was similar in the PRISm and airflow limitation groups. The PRISm group had higher mean body mass index and a higher proportion of comorbid metabolic disease compared with the airflow limitation group. The prevalence of airflow limitation and PRISm was highest among current smokers (3.9% and 21.3%, respectively) versus former or never smokers. Conclusion A significant proportion of Japanese individuals <60 years of age attending their annual health examination had impaired lung function (airflow limitation and PRISm); prevalence was highest among current smokers. These findings support screening of current or former smokers ≥40 years of age using patient-reported questionnaires to inform the need for spirometry to confirm an OAD diagnosis.

“…We read with interest the article by Tamaki et al who in the OCEAN study compared the performance characteristics of the CAPTURE COPD screening tool with the COPD-Q screening tool. 1 While there is currently an important focus on better understanding the broader scope of symptomatic chronic lung disease, it is useful to remember that the CAPTURE was designed specifically to be used as a screening tool (meaning to be used among those without a COPD diagnosis) for the identification of individuals with clinically significant COPD.…”
