Organisational contextual drivers of evidence-based practice across acute and primary care.

backgroundEvidence based practice (EBP) is widely recognised as fundamental to high quality nursing care, yet implementation remains uneven across healthcare settings in England. Attention has shifted from individual barriers to organisational context. Leadership, team dynamics, access to resources, and social capital shape how nurses engage with EBP. Despite national policies promoting research active environments, how these ambitions are realised at the frontline is unclear. This study examined how organisational factors influence nurses’ implementation of evidence across acute and primary care.

methodsA cross-sectional design was used with registered nurses working in acute and primary care settings. Two validated instruments, the Evidence Based Practice Implementation Scale and the Alberta Context Tool, were administered. A nonprobability sampling strategy targeted the acute and general practice nursing workforce. Response distributions were monitored across pre specified strata and fieldwork closed once coverage and precision criteria were met. Descriptive statistics summarised participant and organisational characteristics. Inferential analyses compared settings, mediation modelling tested the role of social capital in the leadership to EBP pathway, and cluster analysis identified implementation profiles.

resultsEngagement with EBP was moderate overall (M = 3.16, SD = 0.88) with no significant difference between sectors (p = 0.38). Acute care nurses reported higher leadership support (M = 4.01 versus 3.78, p = 0.008) and better access to structural resources (M = 3.35 vs. 3.10, p = 0.004). Within acute care, leadership differed across specialties, with higher scores in ICU or CCU and general medicine, F (4, 636) = 4.12, p = 0.003. Social capital significantly mediated the association between leadership and EBP implementation (β = 0.15, 95% CI 0.10–0.21). Three engagement clusters were identified, high 32%, moderate 45%, and low 23%, each with distinct organisational profiles.

conclusionOrganisational context, particularly leadership and social capital, is central to nurses’ capacity to implement evidence. Variation across specialties and sectors indicates that a one size fits all approach is unlikely to succeed. Policy relevant levers include formalising protected time, resourcing embedded facilitation, investing in knowledge infrastructure, and expanding clinical academic pathways, to create environments where evidence use is routine and supported.
