Intensification of Implementation Strategies: Developing a Model of Foundational and Enhanced Implementation Approaches to Support National Adoption and Scale-up.

Implementation strategies are activities to support integration of evidence-based programs (EBPs) into routine care. Comprised of 170+ facilities, the Veterans Affairs Healthcare System is conducive to evaluating feasibility and scalability of implementation strategies on a national level. In previous work evaluating implementation of three EBPs for older Veterans (hospital-based walking, caregiver skills training, group physical therapy), we found facilities varied in their need for implementation support, with some needing minimal guidance and others requiring intensive support. Committed to national scalability, our team developed an implementation intensification model consisting of foundational (low-touch) and enhanced (high-touch) implementation support. This Forum article describes our multilevel and multistep process to develop and evaluate implementation intensification. Steps included (a) review completed trial data; (b) conduct listening sessions; (c) review literature; (d) draft foundational and enhanced implementation support packages; (e) iteratively refine packages; and (7) devise an evaluation plan. Our model of implementation intensification may be relevant to other health care systems seeking strategies that can adapt to diverse delivery settings, optimize resources, help build capacity, and ultimately enhance implementation outcomes. As more health care systems focus on spread of EBPs into routine care, identifying scalable and effective implementation strategies will be critical.

Insomnia in United States military veterans: An integrated theoretical model.

Marked by difficulty falling or staying asleep and/or poor sleep leading to daytime dysfunction, insomnia contributes to functional impairment, poor health, and increased healthcare utilization when left untreated. As many as two-thirds of Iraq and Afghanistan military veterans complain of insomnia. Older veterans of prior conflicts report insomnia occurring since initial service, suggesting a chronic nature to insomnia in this population. Despite insomnia's high prevalence and severe consequences, there is no theoretical model to explain either the onset or chronicity of insomnia in this growing patient population. Existing theories view insomnia as an acute, unidirectional phenomenon and do little to elucidate long-term consequences of such problems. Existing theories also fail to address mechanisms by which acute insomnia becomes chronic. This paper presents an original, integrated theoretical model that draws upon constructs from several prominent behavioral medicine theories to reconceptualize insomnia as a chronic, cyclical problem that is both a consequence and predictor of stress. Additional research examining the relationships between stress, sleep, resilience, and outcomes of interest could inform clinical and research practices. Addressing sleep problems early could potentially enhance adaptive capacity, thereby reducing the risk for subsequent negative outcomes.
