Abstract Background Supported asthma self-management, incorporating an asthma action plan and annual clinical review, has been recommended by UK/global guidelines for over three decades. However, implementation remains poor, as only around a third of individuals receive basic asthma care, according to the UKs leading respiratory charity Asthma and Lung UK. A systematic review of implementation studies recommended that a whole systems approach targeting patients, healthcare professional education, and organisations is needed to improve implementation of supported asthma self-management in primary care. The IMPlementing IMProved Asthma self-management as RouTine (IMP2ART) is a national Hybrid-II implementation cluster randomised controlled trial that aims to evaluate such an approach. This paper describes the development of the implementation strategy for IMP2ART with particular focus on the integration of multiple level theories. Methods The Medical Research Council design and evaluation of complex interventions framework and the Person-Based Approach to intervention development were used as guidance for stages of strategy development. Specifically, we (i) set up a multidisciplinary team (including practicing and academic clinicians, health psychologists, public health and patient colleagues), (ii) reviewed and integrated evidence and theory, (iii) developed guiding principles, (iv) developed prototype materials, and (v) conducted a pre-pilot study before final refinement. Results The implementation strategy included resources for patients, team-based and individual healthcare professional education, practice audit and feedback, and an asthma review template, as well as a facilitator role accessible to primary care practices for 12 months. The synthesis of the integrated Promoting Action on Research Implementation in Health Services (iPARIHS) and Capability, Opportunity, Motivation and Behaviour (COM-B) frameworks led to an evolved framework bringing together important implementation and behaviour change elements which will be used as a basis for the study process evaluation. Conclusions A description of rigorous implementation strategy development for the IMP2ART study is provided along with newly theorised integration of implementation and behaviour change science which may be of benefit to others targeting implementation in primary care.
