OBJECTIVES/GOALS: COPD is a progressive airways disease that results in death or disability. There is poor uptake of clinical guidelines (CPG) to manage COPD and studies to bridge this implementation gap have shown inconsistent results. Using implementation science principles we aim to understand COPD-CPG implementation determinants from providers’perspective. METHODS/STUDY POPULATION: The study is being conducted in ten VA Primary Care Clinics. Guided by the Consolidated Framework for Implementation Research (CFIR), a conceptual framework developed to guide systematic assessment of multilevel implementation contexts, we are using semi-structured guides to conduct key informant qualitative interviews (physicians, physician extenders and nurses), to support a formative evaluation. CFIR domains relevant to the study were determined by a multidisciplinary team. Informants are identified through online outreach and voluntary participation. Sampling adequacy will be assessed by achievement of code saturation. A qualitative template analysis will be used to summarize the barriers and facilitators of each component of COPD-CPG organized by CFIR-domain. RESULTS/ANTICIPATED RESULTS: We anticipate a list of modifiable and non-modifiable contextual, recipient (provider and patient), and COPD CPG content (innovation) barriers to implementation. Many settings do not have critical elements of these CPG, such as a standardized inhaler education/assessment pathway, patient education material, or pulmonary rehabilitation referral pathway. Existing literature indicate reasons behind the insufficient uptake of COPD CPG include low familiarity with guidelines, perception of minimal value of guidelines by physicians, and time constraints; we will present contextual, recipient and innovation determinants specific to our setting. DISCUSSION/SIGNIFICANCE: This comprehensive assessment of barriers and facilitators to COPD-CPG will inform tool development and implementation strategies identification to improve COPD CPG uptake. COPD is the most common veteran lung disease. Improvement in COPD care has enormous potential for benefit for local veterans, as well as potential for wider dissemination.
