Determinants of Evidence-based Practice Uptake in Rural Intensive Care Units. A Mixed Methods Study.

Rationale: Evidence-based practices promote quality care for intensive care unit patients but chronic evidence-to-practice gaps limit their reach.Objectives: To characterize key determinants of evidence-based practice uptake in the rural intensive care setting.Methods: A parallel convergent mixed methods design was used with six hospitals receiving a quality improvement intervention. Guided by implementation science principles, we identified barriers and facilitators to uptake using clinician surveys (N = 90), key informant interviews (N = 14), and an implementation tracking log. Uptake was defined as completion of eight practice change steps within 12 months. After completing qualitative and quantitative data analyses for each hospital, site, staff, and program delivery factors were summarized within and across hospitals to identify patterns by uptake status.Results: At the site level, although structural characteristics (hospital size, intensivist staffing) did not vary by uptake status, interviews highlighted variability in staffing patterns and culture that differed by uptake status. At the clinician team level, readiness and self-efficacy were consistently high across sites at baseline with time and financial resources endorsed as primary barriers. However, interviews highlighted that as initiatives progressed, differences across sites in attitudes and ownership of change were key uptake influences. At the program delivery level, mixed methods data highlighted program engagement and leadership variability by uptake status. Higher uptake sites had better training attendance; more program activities completed; and a stable, engaged, collaborative nurse and physician champion team.Conclusions: Results provide an understanding of the multiple dynamic influences on different patterns of evidence-based practice uptake and the importance of implementation support strategies to accelerate uptake in the intensive care setting.

Implementation of an Academic-to-Community Hospital Intensive Care Unit Quality Improvement Program. Qualitative Analysis of Multilevel Facilitators and Barriers.

Rationale: Implementation of evidence-based best practices is influenced by a variety of contextual factors. It is vital to characterize such factors to maintain high-quality care. Patients in the intensive care unit (ICU) are critically ill and require complex, interdisciplinary, evidence-based care to enable high-quality outcomes. Objectives: To identify facilitators and barriers to implementation of an academic-to-community hospital ICU interprofessional quality improvement program, "ICU Innovations." Methods: ICU Innovations is a multimodal quality improvement program implemented between 2014 and 2017 in six community ICUs in rural settings serving underserved patients in South Carolina. ICU Innovations includes quarterly on-site seminars and extensive behind the scenes facilitation to catalyze the implementation of evidence-based best practices. We use qualitative analysis to identify contextual factors related to program implementation processes. Guided by an implementation science framework, the Exploration, Adoption/Preparation, Implementation, Sustainment framework, we conducted semistructured key informant interviews with clinician champions at six community ICUs and six parallel interviews with ICU Innovations' leadership. We developed a qualitative coding template based on the framework and identified contextual factors associated with implementation. Standard data on hospital and ICU structure and processes of care were also collected. Results: Outer and inner factors interconnected dynamically to influence implementation of ICU Innovations. Collaborative engagement between the program developers and partner sites (outer context factor) and site program champion leadership and staff readiness for change (inner context factors) were key influences of implementation. Conclusions: This research focused on rural hospital ICUs with limited or nonexistent intensivist leadership. Although enthusiasm for the ICU Innovations program was initially high, implementation was challenging because of multiple contextual factors. Critical steps for implementation of evidence-based practice in rural hospitals include optimizing engagement with external collaborators, maximizing the role of a committed site champion, and conducting thorough site assessments to ensure staff and organizational readiness for change. Identifying barriers and facilitators to program implementation is an on-going process to tailor and improve program initiatives.
