This study investigated whether the implementation of a multicomponent intervention project could improve compliance with the New South Wales (NSW) Health smoke-free healthcare policy. Environmental interventions were implemented on the hospital grounds for a 12-week period. Compliance was measured by a pre- and postintervention observational count of smokers on the hospital grounds. After implementation, there was a significant 73% reduction in people smoking on the hospital grounds, indicating improved compliance with the NSW smoke-free healthcare policy through the use of a non-punitive multicomponent intervention.
