Purpose: The purpose of this study was to examine the organizational context that may support learning and change readiness climates that previous research has found to be conducive to implementing evidence-based interventions. Design/methodology/approach: An exploratory, mixed method evaluation that included 15 rheumatology clinics throughout the United States was performed. Quantitative data were collected using a web-based survey completed by 135 clinic members. Qualitative data were collected via semi-structured interviews with 88 clinic members. Findings: In general, clinics reported strong, positive learning and change readiness climates. More complex organizations (e.g. multispecialty, academic medical centers) with rational/hierarchical cultures and members with longer tenure were associated with less supportive learning and change readiness climates. The authors’ findings highlight opportunities for organizational leaders and evidence-based intervention sponsors to focus their attention and allocate resources to settings that may be most susceptible to implementation challenges. Originality/value: First, the authors address a deficit in previous research by describing both the level and strength of the learning and change readiness climates for implementing an evidence-based shared decision-making aid (SDMA) and examine how these vary as a function of the organizational context. Second, the study examines a broader set of factors to assess the organizational context (e.g. organizational culture, organizational structure, ownership) than previous research, which may be especially salient for shaping the climate in smaller specialty clinics like those we study. Third, the authors utilize a mixed methods analysis to provide greater insights into questions of how and why organizational factors such as size and structure may influence the learning and change readiness climate.
