BOHRF Original Authors' Main Conclusions

The original authors' main conclusions are taken from Abstract, Results and Discussion. They are decided upon by the authors of the BOHRF occupational asthma guidelines and form part of the guidelines.

The surveillance questionnaire in this study was sensitive but not specific. Spirometry did not result in detection of asthma in any patients who denied respiratory symptoms. Nevertheless it remains possible that workers may have been more honest in admitting symptoms on the questionnaire, knowing that an objective breathing test was also being performed. In companies where workers are more fearful of losing their job, there may be less honest completion of health questionnaires and an objective tests such as spirometry may have been more beneficial in such a setting.
