Asthma 004.1 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.

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 004.2 Reporting and verification

See indicator wording for requirement criteria.

A number of the "Smoking Habit" codes have been removed from the relevant code clusters from April 2014 as they cannot be used to identify if the patient is a current smoker, an ex-smoker or has never smoked. Accepted codes are available in the associated Business Rules
