Survey on the handling of chronic obstructive pulmonary disease by annual health check in Japan.
OBJECTIVE
Since mild COPD can be detected in the annual health check by lung function tests, we conducted a questionnaire survey on how such examinations are used to assess chronic obstructive pulmonary disease (COPD).


METHODS
We mailed questionnaires to 633 facilities performing comprehensive medical check-up from June to July 2005 and obtained responses from 254 (40.1%).


RESULTS
At participating facilities, the proportion of full or part-time physicians specializing in respiratory diseases was low [40 of 366 full timers (10.9%) and 114 of 2,044 part-timers (5.6%)], with very few physicians certified by the Japanese Respiratory Society (6.8%). Non respiratory physicians were involved in evaluating the results of thoracic diagnostic imaging at 32 facilities. Lung function tests were carried out at 98.2% of facilities though relatively few facilities evaluated test results with COPD in mind. All stages (mild, moderate, severe) of COPD were diagnosed in patients at 85 facilities (39.2%), while only severe COPD was targeted by chest imaging at 97 facilities (44.7%), disregarding mild and moderate cases. Counseling for smoking cessation was provided at 113 facilities (20.6%), while 30 facilities (14.4%) provided no form of smoking cessation.


CONCLUSIONS
At most facilities performing a comprehensive medical check-up, there was not a sufficient number of respirologists to ensure early diagnosis of COPD and this may have compromised COPD diagnosis. The newly proposed Japan Society of Comprehensive Medical Check-up (Ningen-dock) Standards based on the Japanese Respiratory Society may be useful to reveal early stages of COPD.
