How effective are psychosocial interventions in helping people with coronary heart disease (CHD) to quit smoking?
The validation of smoking status was not a standard procedure in the trials, with only 7 trials describing any measure of biochemical validation. There were no studies comparing psychosocial interventions with pharmacological therapy (eg, nicotine replacement therapy) or with pharmacological therapy plus psychosocial interventions.
Smoking is a major risk factor for CHD, and stopping smoking lowers that risk. Psychosocial interventions that can assist quitting and promote abstinence include behavioural counselling, telephone support and self-help interventions.
