Approximately one in every ten cases of adult-onset asthma is attributable to
occupational exposure. Unless occupation is considered, a diagnosis of occupational
asthma will be missed so it is likely to be underdiagnosed. An average practice with
around 6,000 patients will typically have approximately 600 adult patients with asthma,
of whom 60 may have occupational asthma if we assume 10% of cases are related to
occupational exposure. Can you think of 60 patients with occupational asthma in your practice?
