Spirometry practice and the impact of a phase 1 training workshop among health workers in southern Nigeria: a cross-sectional study.

The present study has shown that a one-day spirometry workshop significantly improved the knowledge of spirometry practice. There is need to set up more frequent locally-organized spirometry workshops since a one-day seven-hour effective knowledge and practical training would most likely have significant impact on participants' spirometry practice with its expected positive outcome on respiratory health in Nigeria.
