Background Health and social care standards have been widely adopted as a quality improvement intervention. Standards are typically made up of evidence-based statements that describe safe, high-quality, person-centred care as an outcome or process of care delivery. They involve stakeholders at multiple levels and multiple activities across diverse services. As such, challenges exist with their implementation. Existing literature relating to standards has focused on accreditation and regulation programmes and there is limited evidence to inform implementation strategies specifically tailored to support the implementation of standards. This systematic review aimed to identify and describe the most frequently reported enablers and barriers to implementing (inter)nationally endorsed standards, in order to inform the selection of strategies that can optimise their implementation.

Methods Database searches were conducted in Medline, CINAHL (Cumulative Index to Nursing and Allied Health Literature), SocINDEX, Google Scholar, OpenGrey and GreyNet International, complemented by manual searches of standard-setting bodies’ websites and hand searching references of included studies. Primary qualitative, quantitative descriptive and mixed methods studies that reported enablers and barriers to implementing nationally or internationally endorsed standards were included. Two researchers independently screened search outcomes and conducted data extraction, methodological appraisal and CERQual (Confidence in Evidence from Reviews of Qualitative research) assessments. An inductive analysis was conducted using Sandelowski’s meta-summary and measured frequency effect sizes (FES) for enablers and barriers.

Results 4072 papers were retrieved initially with 35 studies ultimately included. Twenty-two thematic statements describing enablers were created from 322 descriptive findings and grouped under six themes. Twenty-four thematic statements describing barriers were created from 376 descriptive findings and grouped under six themes. The most prevalent enablers with CERQual assessments graded as high included: available support tools at local level (FES 55%); training courses to increase awareness and knowledge of the standards (FES 52%) and knowledge sharing and interprofessional collaborations (FES 45%). The most prevalent barriers with CERQual assessments graded as high included: a lack of knowledge of what standards are (FES 63%), staffing constraints (FES 46%), insufficient funds (FES 43%).

Conclusions The most frequently reported enablers related to available support tools, education and shared learning. The most frequently reported barriers related to a lack of knowledge of standards, staffing issues and insufficient funds. Incorporating these findings into the selection of implementation strategies will enhance the likelihood of effective implementation of standards and subsequently, improve safe, quality care for people using health and social care services.
