Background To successfully reduce the negative impacts of stroke, high-quality health and care practices are needed across the entire stroke care pathway. These practices are not always shared across organisations. Quality improvement collaboratives (QICs) offer a unique opportunity for key stakeholders from different organisations to share, learn and ‘take home’ best practice examples, to support local improvement efforts. This systematic review assessed the effectiveness of QICs in improving stroke care and explored the facilitators and barriers to implementing this approach. Methods Five electronic databases (MEDLINE, CINAHL, EMBASE, PsycINFO, and Cochrane Library) were searched up to June 2020, and reference lists of included studies and relevant reviews were screened. Studies conducted in an adult stroke care setting, which involved multi-professional stroke teams participating in a QIC, were included. Data was extracted by one reviewer and checked by a second. For overall effectiveness, a vote-counting method was used. Data regarding facilitators and barriers was extracted and mapped to the Consolidated Framework for Implementation Research (CFIR). Results Twenty papers describing twelve QICs used in stroke care were included. QICs varied in their setting, part of the stroke care pathway, and their improvement focus. QIC participation was associated with improvements in clinical processes, but improvements in patient and other outcomes were limited. Key facilitators were inter- and intra-organisational networking, feedback mechanisms, leadership engagement, and access to best practice examples. Key barriers were structural changes during the QIC’s active period, lack of organisational support or prioritisation of QIC activities, and insufficient time and resources to participate in QIC activities. Patient and carer involvement, and health inequalities, were rarely considered. Conclusions QICs are associated with improving clinical processes in stroke care; however, their short-term nature means uncertainty remains as to whether they benefit patient outcomes. Evidence around using a QIC to achieve system-level change in stroke is equivocal. QIC implementation can be influenced by individual and organisational level factors, and future efforts to improve stroke care using a QIC should be informed by the facilitators and barriers identified. Future research is needed to explore the sustainability of improvements when QIC support is withdrawn. Trial registration Protocol registered on PROSPERO (CRD42020193966).

ObjectiveTo systematically review all published and unpublished evidence on the impact of the COVID-19 pandemic on the health and well-being of UK sexual and gender minority (LGBT+; lesbian, gay, bisexual, transgender, non-binary, intersex and queer) people.MethodsAny relevant studies with or without comparator were included, with outcomes of: COVID-19 incidence, hospitalisation rates, illness severity, death rates, other health and well-being. Six databases (platforms) were searched—CINAHL Plus (Ovid), Cochrane Central (Cochrane Library), Medline (Ovid), Embase (Ovid), Science Citation Index (Web of Science) and Scopus between 2019 and 2020 in December 2020, using synonyms for sexual and gender minorities and COVID-19 search terms. Data extraction and quality assessment (using the relevant Joanna Briggs checklist) were in duplicate with differences resolved through discussion. Results were tabulated and synthesis was through narrative description.ResultsNo published research was found on any outcomes. Eleven grey literature reports found to be of low quality were included, mostly conducted by small LGBT+ charities. Only four had heterosexual/cisgender comparators. Mental health and well-being, health behaviours, safety, social connectedness and access to routine healthcare all showed poorer or worse outcomes than comparators.ConclusionsLack of research gives significant concern, given pre-existing health inequities. Social and structural factors may have contributed to poorer outcomes (mental health, well-being and access to healthcare). Paucity of evidence is driven by lack of routinely collected sexual orientation and gender identity data, possibly resulting from institutional homophobia/transphobia which needs to be addressed. Men are more at risk of serious illness from COVID-19 than women, so using data from trans women and men might have started to answer questions around whether higher rates were due to sex hormone or chromosomal effects. Routine data collection on sexual orientation and gender identity is required to examine the extent to which COVID-19 is widening pre-existing health inequalities.PROSPERO registration numberCRD42020224304.

Stroke remains one of the leading causes of death worldwide. To tackle the negative impacts of stroke, a high standard of clinical practice and a commitment to continuous quality improvement is needed across the stroke care pathway. One approach to quality improvement is the formation and implementation of quality improvement collaboratives. However, there are several barriers to the implementation of a quality improvement collaborative for stroke care which may impact on its success. This article critically appraises a systematic review that assessed the effectiveness of quality improvement collaboratives for driving improvements in stroke care and explored the barriers to implementing a quality improvement collaborative to improve care.
