This is the protocol for a review and there is no abstract. The objectives are as follows:
The primary objective of the review is to assess the effects of interventions on adherence to medications shown to be effective for smoking cessation, such as NRT, bupropion, nortriptyline and varenicline (and combination regimens). This will be considered in comparison to levels of adherence in a control group, typically expected to represent standard care, to determine whether there are strategies that can be used to increase adherence. Secondary objectives are to i) assess which intervention approaches are most effective; ii) determine the impact of interventions on potential precursors of adherence, such as understanding of the treatment and efficacy perceptions; and iii) evaluat e key outcomes influenced by prior adherence, principally smoking cessation.
