The Gap Between Clinical Guidelines and Routine Practice: Barriers and Facilitators Across Healthcare Professions Guideline–Practice Gap Across Healthcare Professions

Abstract

Background. Clinical practice guidelines are the principal vehicle for translating research into care, yet across health systems only around 60% of care is consistent with evidence- or consensus-based recommendations. The gap between what guidelines recommend and what patients receive results in avoidable harm, low-value care and inequity. Although guidelines are increasingly interprofessional, most implementation research has focused on physicians.
Objective. To synthesize evidence on the magnitude and consequences of the guideline–practice gap; to identify barriers and facilitators at the levels of the guideline, the professional, the team, the organization and the wider system, with attention to differences between professions; to appraise the effectiveness of implementation strategies; and to propose an integrated, theory-informed framework.
Methods. Narrative review informed by the SANRA criteria, drawing on MEDLINE, CINAHL, Embase and the Cochrane Library, and on established implementation frameworks including the Consolidated Framework for Implementation Research (CFIR), the Theoretical Domains Framework (TDF), the COM-B model and i-PARIHS.
Results. Barriers are multilevel and interacting: guideline characteristics (complexity, poor applicability, conflicting recommendations), professional factors (knowledge, skills, beliefs about consequences, professional role and autonomy), team factors (hierarchy and role ambiguity), organizational factors (time, staffing, leadership, information systems) and system factors (incentives, regulation, patient preferences). Physicians more often cite autonomy and applicability to individual patients; nurses and allied professionals more often cite authority to act, workload and organizational support. Single strategies produce small improvements: audit and feedback yields a median absolute improvement of about 3%, and computerized decision support about 6%. Tailored, multifaceted strategies addressing identified barriers, delivered with facilitation and leadership, are more effective.
Conclusions. Closing the guideline–practice gap requires moving from dissemination to implementation: diagnosing barriers profession by profession, selecting matched strategies and embedding guidelines into workflows and systems. The proposed CLOSE framework (Contextualize, Lead and engage, Optimize systems, Support capability, Evaluate and embed) provides a practical pathway, with particular relevance to health systems undergoing transformation, such as Saudi Arabia under Vision 2030.
