Asthma 3.1 Rationale
Many young people start to smoke at an early age. It is therefore justifiable
to ask about smoking on an annual basis in this age group.
The number of studies of smoking related to asthma are surprisingly few in
number. Starting smoking as a teenager increases the risk of persisting asthma.
There are very few studies that have considered the question of whether smoking
affects asthma severity. One controlled cohort study suggested that exposure
to passive smoke at home delayed recovery from an acute attack. There is also
epidemiological evidence that smoking is associated with poor asthma control.
See Price
et al. Clin Exp Allergy 2005; 35: 282-287.
It is recommended that smoking cessation be encouraged as it is good for general
health and may decrease asthma severity (Thomson
et al. Eur Respir J 2004; 24: 822 – 833).
Asthma 3.2 Reporting and verification
Practices should report the percentage of patients on the asthma register between
the ages of 14 and 19 where smoking status has been recorded in the previous
15 months.
