Factors predicting recruitment to a UK wide primary care smoking cessation study (the ESCAPE trial)

摘要

Background. Recruiting smokers to smoking cessation trials is challenging and participation rates are often low. Consequently, the interventions evaluated may fail to reach a broad spectrum of the target population, thus compromising the generalizability of the findings. Brief interventions, using proactive recruitment, are likely to attract a broader and more representative proportion of the population.
