Push or pull? Digital notification platform implementation reduces dysglycaemia.

Pushing selected information to clinicians, as opposed to the traditional method of clinicians pulling information from an electronic medical record, has the potential to improve care. A digital notification platform was designed by clinicians and implemented in a tertiary hospital to flag dysglycaemia. There were 112 patients included in the study, and the post-implementation group demonstrated lower rates of dysglycaemia (2.5% vs 1.1%, P = 0.038). These findings raise considerations for information delivery methods for multiple domains in contemporary healthcare.

Exploring the impact of housing insecurity on the health and wellbeing of children and young people in the United Kingdom: a qualitative systematic review.

BACKGROUND: Housing insecurity can be understood as experiencing or being at risk of multiple house moves that are not through choice and related to poverty. Many aspects of housing have all been shown to impact children/young people's health and wellbeing. However, the pathways linking housing and childhood health and wellbeing are complex and poorly understood. METHODS: We undertook a systematic review synthesising qualitative data on the perspectives of children/young people and those close to them, from the United Kingdom (UK). We searched databases, reference lists, and UK grey literature. We extracted and tabulated key data from the included papers, and appraised study quality. We used best fit framework synthesis combined with thematic synthesis, and generated diagrams to illustrate hypothesised causal pathways. RESULTS: We included 59 studies and identified four populations: those experiencing housing insecurity in general (40 papers); associated with domestic violence (nine papers); associated with migration status (13 papers); and due to demolition-related forced relocation (two papers). Housing insecurity took many forms and resulted from several interrelated situations, including eviction or a forced move, temporary accommodation, exposure to problematic behaviour, overcrowded/poor-condition/unsuitable property, and making multiple moves. Impacts included school-related, psychological, financial and family wellbeing impacts, daily long-distance travel, and poor living conditions, all of which could further exacerbate housing insecurity. People perceived that these experiences led to mental and physical health problems, tiredness and delayed development. The impact of housing insecurity was lessened by friendship and support, staying at the same school, having hope for the future, and parenting practices. The negative impacts of housing insecurity on child/adolescent health and wellbeing may be compounded by specific life circumstances, such as escaping domestic violence, migration status, or demolition-related relocation. CONCLUSION: Housing insecurity has a profound impact on children and young people. Policies should focus on reducing housing insecurity among families, particularly in relation to reducing eviction; improving, and reducing the need for, temporary accommodation; minimum requirements for property condition; and support to reduce multiple and long-distance moves. Those working with children/young people and families experiencing housing insecurity should prioritise giving them optimal choice and control over situations that affect them.

Contexts, behavioural mechanisms and outcomes to optimise therapeutic exercise prescription for persistent low back pain: a realist review.

OBJECTIVE: Therapeutic exercises are a core treatment for low back pain (LBP), but it is uncertain how rehabilitative exercise facilitates change in outcomes. Realist reviews explore how the context (C) of certain settings or populations and underlying mechanisms (M) create intended or unintended outcomes (O). Our objective was to explore and understand the behavioural mechanisms by which therapeutic exercise creates change in outcomes of adherence, engagement and clinical outcomes for patients with LBP. METHODS: This was a realist review reported following the Realist and Meta-narrative Evidence Syntheses: Evolving Standards guidance. We developed initial programme theories, modified with input from a steering group (experts, n=5), stakeholder group (patients and clinicians, n=10) and a scoping search of the published literature (n=37). Subsequently, an information specialist designed and undertook an iterative search strategy, and we refined and tested CMO configurations. RESULTS: Of 522 initial papers identified, 75 papers were included to modify and test CMO configurations. We found that the patient-clinician therapeutic consultation builds a foundation of trust and was associated with improved adherence, engagement and clinical outcomes, and that individualised exercise prescription increases motivation to adhere to exercise and thus also impacts clinical outcomes. Provision of support such as timely follow-up and supervision can further facilitate motivation and confidence to improve adherence to therapeutic exercises for LBP. CONCLUSIONS: Engagement in and adherence to therapeutic exercises for LBP, as well as clinical outcomes, may be optimised using mechanisms of trust, motivation and confidence. These CMO configurations provide a deeper understanding of ways to optimise exercise prescription for patients with LBP.

Topological and Morphological Membrane Dynamics in Giant Lipid Vesicles Driven by Monoolein Cubosomes.

Lipid nanoparticles have important applications as biomedical delivery platforms and broader engineering biology applications in artificial cell technologies. These emerging technologies often require changes in the shape and topology of biological or biomimetic membranes. Here we show that topologically-active lyotropic liquid crystal nanoparticles (LCNPs) can trigger such transformations in the membranes of giant unilamellar vesicles (GUVs). Monoolein (MO) LCNPs, cubosomes with an internal nanostructure of space group Im3m incorporate into 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) GUVs creating excess membrane area with stored curvature stress. Using time-resolved fluorescence confocal and lattice light sheet microscopy, we observe and characterise various life-like dynamic events in these GUVs, including growth, division, tubulation, membrane budding and fusion. Our results shed new light on the interactions of LCNPs with bilayer lipid membranes, providing insights relevant to how these nanoparticles might interact with cellular membranes during drug delivery and highlighting their potential as minimal triggers of topological transitions in artificial cells.

Factors that impact on recruitment to vaccine trials in the context of a pandemic or epidemic: a qualitative evidence synthesis.

BACKGROUND: The World Health Organization declared the COVID-19 pandemic on 11 March 2020. Vaccine development and deployment were swiftly prioritised as a method to manage and control disease spread. The development of an effective vaccine relies on people's participation in randomised trials. Recruitment to vaccine trials is particularly challenging as it involves healthy volunteers who may have concerns around the potential risks and benefits associated with rapidly developed vaccines. OBJECTIVES: To explore the factors that influence a person's decision to participate in a vaccine trial in the context of a pandemic or epidemic. SEARCH METHODS: We used standard, extensive Cochrane search methods. The latest search date was June 2021. SELECTION CRITERIA: We included qualitative studies and mixed-methods studies with an identifiable qualitative component. We included studies that explored the perspectives of adults aged 18 years or older who were invited to take part in vaccine trials in the context of a pandemic or epidemic. DATA COLLECTION AND ANALYSIS: We assessed the title, abstracts and full texts identified by the search. We used a sampling frame to identify data-rich studies that represented a range of diseases and geographical spread. We used QSR NVivo to manage extracted data. We assessed methodological limitations using an adapted version of the Critical Skills Appraisal Programme (CASP) tool for qualitative studies. We used the 'best-fit framework approach' to analyse and synthesise the evidence from our included studies. We then used the Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual) assessment to assess our confidence in each finding and develop implications for practice. MAIN RESULTS: We included 34 studies in our review. Most studies related to HIV vaccine trials. The other studies related to Ebola virus, tuberculosis, Zika virus and COVID-19. We developed 20 key findings, under three broad themes (with seven subthemes), that described the factors that people consider when deciding whether to take part in a vaccine trial for a pandemic or epidemic disease. Our GRADE-CERQual confidence was high in nine of the key findings, moderate in 10 key findings and low in one key finding. The main reason for downgrading review findings were concerns regarding the relevance and adequacy of the underlying data. As a result of the over-representation of HIV studies, our GRADE-CERQual assessment of some findings was downgraded in terms of relevance because the views described may not reflect those of people regarding vaccine trials for other pandemic or epidemic diseases. Adequacy relates to the degree of richness and quantity of data supporting a review finding. Moderate concerns about adequacy resulted in a downgrading of some review findings. Some factors were considered to be under the control of the trial team. These included how trial information was communicated and the inclusion of people in the community to help with trial information dissemination. Aspects of trial design were also considered under control of the trial team and included convenience of participation, provision of financial incentives and access to additional support services for those taking part in the trial. Other factors influencing people's decision to take part could be personal, from family, friends or wider society. From a personal perceptive, people had concerns about vaccine side effects, vaccine efficacy and possible impact on their daily lives (carer responsibilities, work, etc.). People were also influenced by their families, and the impact participation may have on relationships. The fear of stigma from society influenced the decision to take part. Also, from a societal perspective, the level of trust in governments' involvement in research and trial may influence a person's decision. Finally, the perceived rewards, both personal and societal, were influencing factors on the decision to participate. Personal rewards included access to a vaccine, improved health and improved disease knowledge, and a return to normality in the context of a pandemic or epidemic. Potential societal rewards included helping the community and contributing to science, often motivated by the memories of family and friends who had died from the disease. AUTHORS' CONCLUSIONS: This review identifies many of the factors that influence a person's decision to take part in a vaccine trial, and these reflect findings from reviews that examine trials more broadly. However, we also recognise some factors that become more important in connection with a vaccine trial in the context of a pandemic or epidemic. These factors include the potential stigma of taking part, the possible adverse effects of a vaccine, the added motivation for helping society, the role of community leaders in trial dissemination, and the level of trust placed in governments and companies developing vaccines. These specific influences need to be considered by trial teams when designing, and communicating about, vaccine trials in the context of a pandemic or epidemic.

Delivery of public health interventions by the ambulance sector: a scoping review.

BACKGROUND: With millions of unscheduled patient contacts every year and increasing call outs clustered around the most deprived communities, it is clear the ambulance sector could have a role to play in improving population health. However, the application and value of a public health approach within the ambulance sector has not been comprehensively explored. A scoping review was undertaken to explore the role of the ambulance sector in the delivery of public health interventions and what impact this has on population health and ambulance sector outcomes. METHODS: A search strategy was developed on MEDLINE and translated to other major medical and health related bibliographic databases (Embase; CINAHL; HMIC; Science and Social Sciences Citation Index; Cochrane Library) to identify literature published since 2000 in OECD countries. Targeted grey literature, reference list, and citation searching was also carried out. Search results were downloaded to Microsoft Excel and screened by three reviewers according to pre-determined inclusion / exclusion criteria. Data from included studies, such as the type of activity noted within the paper, the population involved and the public health approach that was utilised, was extracted from within the paper using a data extraction form and narratively synthesised. RESULTS: Fifty-two references were included in the final review (37 database searching; 9 reference list searching; 6 grey literature). Included articles were categorised according to the relevant public health domains and subdomains as articulated by the UK Faculty of Public Health: 1. Health improvement domain: Public health education and advice (Health promotion sub-domain) (n=13) Emergency Services personnel providing vaccines (Disease prevention sub-domain) (n=1) 2. Health care public health domain Paramedicine (Service delivery sub-domain) (n=30) Screening tools and referral pathways used by the ambulance sector (Service delivery sub-domain) (n=28) Health intelligence using ambulance sector data (population health management sub-domain) (n=26) Of note, some domains (e.g. health protection) returned nil results. DISCUSSION: The scoping review demonstrates the breadth of public health related activities in which the ambulance sector is involved. However, an overemphasis on demand management outcomes precludes definitive conclusions on the impact of ambulance sector-led public health initiatives on public health outcomes. Future evaluations of public health initiatives should incorporate wider health system perspectives beyond the immediately apparent remit of the ambulance sector.

The use of GRADE-CERQual in qualitative evidence synthesis: an evaluation of fidelity and reporting.

BACKGROUND: GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative Research) is a methodological approach to systematically and transparently assess how much confidence decision makers can place in individual review findings from qualitative evidence syntheses. The number of reviews applying GRADE-CERQual is rapidly expanding in guideline and other decision-making contexts. The objectives of this evaluation were, firstly, to describe the uptake of GRADE-CERQual in qualitative evidence synthesis by review authors and, secondly, to assess both reporting of and fidelity to the approach. METHODS: The evaluation had two parts. Part 1 was a citation analysis and descriptive overview of the literature citing GRADE-CERQual. Authors worked together to code and chart the citations, first by title and abstract and second by full text. Part 2 was an assessment and analysis of fidelity to, and reporting of, the GRADE-CERQual approach in included reviews. We developed fidelity and reporting questions and answers based on the most recent guidance for GRADE-CERQual and then used NVivo12 to document assessments in a spreadsheet and code full-text PDF articles for any concerns that had been identified. Our assessments were exported to Excel and we applied count formulae to explore patterns in the data. We employed a qualitative content analysis approach in NVivo12 to sub-coding all the data illustrating concerns for each reporting and fidelity criteria. RESULTS: 233 studies have applied the GRADE-CERQual approach, with most (n = 225, 96.5%) in the field of health research. Many studies (n = 97/233, 41.6%) were excluded from full fidelity and reporting assessment because they demonstrated a serious misapplication of GRADE-CERQual, for example interpreting it as a quality appraisal tool for primary studies or reviews. For the remaining studies that applied GRADE-CERQual to assess confidence in review findings, the main areas of reporting concern involved terminology, labelling and completeness. Fidelity concerns were identified in more than half of all studies assessed. CONCLUSIONS: GRADE-CERQual is being used widely within qualitative evidence syntheses and there are common reporting and fidelity issues. Most of these are avoidable and we highlight these as gaps in knowledge and guidance for applying the GRADE-CERQual approach.

The analgesic effect of electroencephalographic neurofeedback for people with chronic pain: A systematic review and meta-analysis.

BACKGROUND: Electroencephalographic (EEG) neurofeedback has been utilized to regulate abnormal brain activity associated with chronic pain. METHODS: In this systematic review, we synthesized the evidence from randomized controlled trials (RCTs) to evaluate the effect of EEG neurofeedback on chronic pain using random effects meta-analyses. Additionally, we performed a narrative review to explore the results of non-randomized studies. The quality of included studies was assessed using Cochrane risk of bias tools, and the GRADE system was used to rate the certainty of evidence. RESULTS: Ten RCTs and 13 non-randomized studies were included. The primary meta-analysis on nine eligible RCTs indicated that although there is low confidence, EEG neurofeedback may have a clinically meaningful effect on pain intensity in short-term. Removing the studies with high risk of bias from the primary meta-analysis resulted in moderate confidence that there remained a clinically meaningful effect on pain intensity. We could not draw any conclusion from the findings of non-randomized studies, as they were mostly non-comparative trials or explorative case series. However, the extracted data indicated that the neurofeedback protocols in both RCTs and non-randomized studies mainly involved the conventional EEG neurofeedback approach, which targeted reinforcing either alpha or sensorimotor rhythms and suppressing theta and/or beta bands on one brain region at a time. A posthoc analysis of RCTs utilizing the conventional approach resulted in a clinically meaningful effect estimate for pain intensity. CONCLUSION: Although there is promising evidence on the analgesic effect of EEG neurofeedback, further studies with larger sample sizes and higher quality of evidence are required.

Medication management in Minority, Asian and Black ethnic older people in the United Kingdom: A mixed-studies systematic review.

WHAT IS NEW AND OBJECTIVES: Older people from ethnic minorities experience the intersectionality of age and ethnicity in relation to complex medication management and polypharmacy. Minority ethnic groups in the United Kingdom are at risk of poor medication management because factors such as cultural beliefs, language barriers, lack of knowledge of how the healthcare system works may affect their ability to safely manage their medications. The aim of this systematic review was to review the literature focussing on medication management in the older population amongst ethnic minority communities in United Kingdom. METHODS: The review was conducted and reported according to methods in the Cochrane Handbook and in the PRISMA 2020 statement using databases such as EMBASE, ASSIA, MEDLINE, PsychINFO and others. Studies conducted in the United Kingdom on individuals over 60 years of age and from a minority ethnic background were included. A thematic analysis was used to synthesize the results. RESULTS AND DISCUSSION: Nine studies (eight from initial searches, one from a search update in 2021) met the inclusion criteria. Three main themes were identified: misbeliefs around medications, poor health literacy, communication and education as possible intervention to improve medication management. Misbeliefs around long-term illnesses exert a negative impact on medication management. Poor health literacy around medications influences patients' adherence to treatments. Poor communication is perceived as barrier to successful medication management. Despite extensive searching, the team identified a limited number of studies and a lack of intersectional studies focussing on minority ethnic groups and the older population. WHAT IS NEW AND CONCLUSION: Our findings suggest tailored education as a possible intervention to improve medication management amongst these minority groups. Future research should look at recruiting participants from specific ethnic groups and from rural as well as urban areas to explore how medication management operates in different areas of the United Kingdom.

A systematic review case study of urgent and emergency care configuration found citation searching of Web of Science and Google Scholar of similar value.

BACKGROUND: Supplementary search methods, including citation searching, are essential if systematic reviews are to avoid producing biased conclusions. Little evidence exists on how to prioritise databases for citation searching or to establish whether using multiple sources is beneficial. OBJECTIVES: A systematic review examining urgent and emergency care reconfiguration was used to investigate the utility of citation searching on Web of Science (WOS) and/or Google Scholar (GS). METHODS: This case study investigated numbers of studies, additional studies and unique studies retrieved from both sources. In addition, the time to search, the ease of adding references to reference management software and obtaining abstracts of studies for screening are briefly considered. RESULTS: WOS retrieved 62 references after deduplication of the results, 52 being additional references not retrieved during the database searching. GS retrieved 134 unique references with 63 additional references. WOS and GS retrieved the same three additional included studies. WOS was less time intensive to search given the facility to restrict to English language papers and availability of abstracts. CONCLUSIONS: In a single systematic review case study, citation searching was required to identify all included studies. Citation searching on WOS is more efficient, where a subscription is available. Both databases identified the same studies but GS required additional time to remove non-English language studies and locate abstracts.

Putting Fine Particulate Matter and Dementia in the Wider Context of Noncommunicable Disease: Where are We Now and What Should We Do Next: A Systematic Review.

INTRODUCTION: A significant proportion of the global population regularly experience air quality poorer than that recommended by the World Health Organization. Air pollution, especially fine particulate matter (PM2.5), is a risk factor for various noncommunicable diseases (NCDs) and is emerging as a risk factor for dementia. To begin to understand the full impact of PM2.5, we review the longitudinal epidemiological evidence linking PM2.5 to both dementia and to other leading NCDs and highlight the evidence gaps. Our objective was to systematically review the current epidemiological evidence for PM2.5 as a risk factor for cognitive decline and incident dementia and to put this in context with a systematic overview of PM2.5 as a potential risk factor in other leading NCDs. METHODS: We performed 2 systematic reviews. A high-level review of reviews examining the relationship between PM2.5 and leading NCDs and an in-depth review of the longitudinal epidemiological data examining relationships between PM2.5 incident dementia and cognitive decline. RESULTS: There were robust associations between PM2.5 and NCDs although in some cases the evidence was concentrated on short rather than longer term exposure. For those articles reporting on incident dementia, all reported on longer term exposure and 5 of the 7 eligible articles found PM2.5 to be associated with increased risk. CONCLUSION: The evidence base for PM2.5 as a risk factor for dementia is growing. It is not yet as strong as that for other NCDs. However, varied measurement/methodology hampers clarity across the field. We propose next steps.

The influence of phosphatidylserine localisation and lipid phase on membrane remodelling by the ESCRT-II/ESCRT-III complex.

The endosomal sorting complex required for transport (ESCRT) organises in supramolecular structures on the surface of lipid bilayers to drive membrane invagination and scission of intraluminal vesicles (ILVs), a process also controlled by membrane mechanics. However, ESCRT association with the membrane is also mediated by electrostatic interactions with anionic phospholipids. Phospholipid distribution within natural biomembranes is inhomogeneous due to, for example, the formation of lipid rafts and curvature-driven lipid sorting. Here, we have used phase-separated giant unilamellar vesicles (GUVs) to investigate the link between phosphatidylserine (PS)-rich lipid domains and ESCRT activity. We employ GUVs composed of phase separating lipid mixtures, where unsaturated DOPS and saturated DPPS lipids are incorporated individually or simultaneously to enhance PS localisation in liquid disordered (Ld) and/or liquid ordered (Lo) domains, respectively. PS partitioning between the coexisting phases is confirmed by a fluorescent Annexin V probe. Ultimately, we find that ILV generation promoted by ESCRTs is significantly enhanced when PS lipids localise within Ld domains. However, the ILVs that form are rich in Lo lipids. We interpret this surprising observation as preferential recruitment of the Lo phase beneath the ESCRT complex due to its increased rigidity, where the Ld phase is favoured in the neck of the resultant buds to facilitate the high membrane curvature in these regions of the membrane during the ILV formation process. Ld domains offer lower resistance to membrane bending, demonstrating a mechanism by which the composition and mechanics of membranes can be coupled to regulate the location and efficiency of ESCRT activity.

Recognition of risk and prevention in safeguarding of children and young people: a mapping review and component analysis of service development interventions aimed at health and social care professionals.

BACKGROUND: The term 'safeguarding' covers the protection of health, wellbeing and human rights. Effective safeguarding enables people (particularly children, young adults and other vulnerable people) to live free from fear of abuse, harm or neglect. The UK Children Act 2004 required key agencies, including health and social care providers, to consider the need to safeguard children and promote their welfare. Within a larger evidence synthesis project, we sought to identify and map service development interventions (excluding provision of training) aimed at improving awareness of safeguarding and identifying at-risk children and young people in health and social care settings. METHODS: We searched fourteen health and social care databases from 2004 (date of Children Act) to October 2019 and updated the review via a citation search in March 2021. Studies of any design were eligible if they described or evaluated an intervention (other than training) aimed at health or social care professionals in the United Kingdom and designed to improve recognition of risk in the context of safeguarding children and young people. Studies with no intervention (e.g. qualitative studies) were included to explain why interventions work or fail to work. Included studies were summarised using narrative synthesis. Risk of bias of included studies and overall strength of evidence were assessed using standard methods. We used a 5-item checklist ("TIDieR-Lite") to map intervention components. RESULTS: Thirty-nine publications were included, of which 31 dealt with service developments, six with use of data and two with other initiatives. Promising service development initiatives include liaison nurses, assessment clinics, secondment, joint protocols and a 'hub and spoke' model. Initiatives involving use of routine data appeared promising and unlikely to generate significant additional costs. However, the quality of the evidence was generally low, with a shortage of controlled and long-term studies. CONCLUSIONS: Health and social care services wishing to improve awareness of child safeguarding issues may benefit from looking beyond high-quality training provision. Future research should focus on service-relevant outcomes and ensure the active involvement of young people and their families/carers.

Knowledge mobilization in bridging patient-practitioner-researcher boundaries: A systematic integrative review.

AIM: To review when, how, and in what context knowledge mobilization (KMb) has crossed patient-practitioner-researcher boundaries. BACKGROUND: KMb is essential in contemporary health care, yet little is known about how patients are engaged. DESIGN: Integrative review. DATA SOURCES: Ten academic databases and grey literature. REVIEW METHODS: We followed integrative review methodology to identify publications from 2006-2019 which contributed to understanding of cross-boundary KMb. We extracted data using a bespoke spreadsheet and the Template for Intervention Description and Replication (TIDieR) framework. We used meta-summary to organize key findings. RESULTS: Thirty-three papers collectively provide new insights into 'when' and 'how' KMb has crossed patient-researcher-practitioner boundaries and the impact this has achieved. Knowledge is mobilized to improve care, promote health, or prevent ill health. Most studies focus on creating or re-shaping knowledge to make it more useful. Knowledge is mobilized in small community groups, in larger networks, and intervention studies. Finding the right people to engage in activities is crucial, as activities can be demanding and time-consuming. Devolving power to communities and using local people to move knowledge can be effective. Few studies report definitive outcomes of KMb. CONCLUSION: Cross-boundary KMb can and does produce new and shared knowledge for health care. Positive outcomes can be achieved using diverse public engagement strategies. KMb process and theory is an emerging discipline, further research is needed on effective cross-boundary working and on measuring the impact of KMb. IMPACT: This review provides new and nuanced understandings of how KMb theory has been used to bridge patient-researcher-practitioner boundaries. We have assessed 'how', 'when', and in what context patients, practitioners and researchers have attempted to mobilize knowledge and identified impact. We have developed a knowledge base about good practice and what can and potentially should be avoided in cross-boundary KMb.

Sustainability of an IPCP program within a federally qualified health center including interprofessional student team placements.

In an effort to improve teamwork and collaborative care at a Federally Qualified Health Center (FQHC), the Midwest Interprofessional Practice, Education, and Research Center (MIPERC) collaborated on the implementation of an interprofessional collaborative practice (IPCP) program that included placement of multidisciplinary student teams. The MIPERC IPCP program supported staff, preceptor and student teams through interprofessional education and structured interprofessional activities for students, including daily huddles, interprofessional student team visits, and nurse triage phone calls. Results from the project's first year were previously reported (Nagelkerk et al., 2017b). Ongoing effects of IPCP on staff morale, IPE knowledge and practice efficiency were measured. Study tools included demographic forms, pre/post module knowledge tests, focus groups and program evaluations. The mean number of clinic patient visits per hour per medical provider was calculated to evaluate practice efficiency. Students (n = 26) and staff (n = 30) demonstrated improvement (p ≤.05) in knowledge test scores for Patient Safety, Team Dynamics and Tips for Behavioral Changes. Providers increased the number of patients seen per hour. Program evaluations and focus group data from providers, staff, and students indicated IPCP programs can be sustainable with ongoing intentional team care strategies.

Effects of service changes affecting distance/time to access urgent and emergency care facilities on patient outcomes: a systematic review.

BACKGROUND: Reconfiguration of urgent and emergency care services often increases travel time/distance for patients to reach an appropriate facility. Evidence of the effects of reconfiguration is important for local communities and commissioners and providers of health services. METHODS: We performed a systematic review of the evidence regarding effects of service reconfigurations that increase the time/distance for some patients to reach an urgent and emergency care (UEC) facility. We searched seven bibliographic databases from 2000 to February 2019 and used citation tracking and reference lists to identify additional studies. We included studies of any design that compared outcomes for people with conditions requiring emergency treatment before and after service reconfiguration with an associated change in travel time/distance to access UEC. Studies had to be conducted in the UK or other developed countries. Data extraction and quality assessment (using the Joanna Briggs Institute checklist for quasi-experimental studies) were undertaken by a single reviewer with a sample checked for accuracy and consistency. We performed a narrative synthesis of the included studies. Overall strength of evidence was assessed using a previously published method that considers volume, quality and consistency. RESULTS: We included 12 studies, of which six were conducted in the USA, two in the UK and four in other European countries. The studies used a variety of observational designs, with before-after and cohort designs being most common. Only two studies included an independent control site/sites where no reconfiguration had taken place. The reconfigurations evaluated in these studies reported relatively small effects on average travel times/distance. DISCUSSION: For studies of general UEC populations, there was no convincing evidence as to whether reconfiguration affected mortality risk. However, evidence of increased risk was identified from studies of patients with acute myocardial infarction, particularly 1 to 4 years after reconfiguration. Evidence for other conditions was inconsistent or very limited. CONCLUSIONS: We found insufficient evidence to determine whether increased distance to UEC increases mortality risk for the general population of people requiring UEC, although this conclusion may not extend to people with specific conditions.

Trajectory of blood pressure, body mass index, cholesterol and incident dementia: systematic review.

BACKGROUND: The global ageing population and the long prodromal period for the development of cognitive decline and dementia brings a need to understand the antecedents of both successful and impaired cognitive ageing. It is increasingly apparent that the trajectory of risk-factor change, as well as the level of the risk factor, may be associated with an increased or decreased risk of cognitive decline or dementia. AIMS: Our aim was to summarise the published evidence and to generate hypotheses related to risk-factor trajectories and risk of incident cognitive decline or dementia. METHOD: We collated data from longitudinal observational studies relating to trajectory of blood pressure, obesity and cholesterol and later cognitive decline or dementia using standard systematic review methodology. The databases MEDLINE, Embase and PsycINFO were searched from inception to 26 April 2018. RESULTS: Thirteen articles were retained for inclusion. Analytical methods varied. Our summary of the current evidence base suggests that first body mass index and then blood pressure rises and then falls more steeply in those who go on to develop dementia. The evidence for cholesterol was less consistent. CONCLUSION: Based on our review we present the hypothesis that weight falls around 10 years and blood pressure around 5 years before diagnosis. Confirmatory work is required. However, characterisation of risk according to combinations and patterns of risk factors may ultimately be integrated into the assessments used to identify those at risk of receiving a diagnosis of cognitive decline or dementia in late life.

Barriers and facilitators to healthcare workers' adherence with infection prevention and control (IPC) guidelines for respiratory infectious diseases: a rapid qualitative evidence synthesis.

BACKGROUND: This review is one of a series of rapid reviews that Cochrane contributors have prepared to inform the 2020 COVID-19 pandemic. When new respiratory infectious diseases become widespread, such as during the COVID-19 pandemic, healthcare workers' adherence to infection prevention and control (IPC) guidelines becomes even more important. Strategies in these guidelines include the use of personal protective equipment (PPE) such as masks, face shields, gloves and gowns; the separation of patients with respiratory infections from others; and stricter cleaning routines. These strategies can be difficult and time-consuming to adhere to in practice. Authorities and healthcare facilities therefore need to consider how best to support healthcare workers to implement them. OBJECTIVES: To identify barriers and facilitators to healthcare workers' adherence to IPC guidelines for respiratory infectious diseases. SEARCH METHODS: We searched OVID MEDLINE on 26 March 2020. As we searched only one database due to time constraints, we also undertook a rigorous and comprehensive scoping exercise and search of the reference lists of key papers. We did not apply any date limit or language limits. SELECTION CRITERIA: We included qualitative and mixed-methods studies (with a distinct qualitative component) that focused on the experiences and perceptions of healthcare workers towards factors that impact on their ability to adhere to IPC guidelines for respiratory infectious diseases. We included studies of any type of healthcare worker with responsibility for patient care. We included studies that focused on IPC guidelines (local, national or international) for respiratory infectious diseases in any healthcare setting. These selection criteria were framed by an understanding of the needs of health workers during the COVID-19 pandemic. DATA COLLECTION AND ANALYSIS: Four review authors independently assessed the titles, abstracts and full texts identified by our search. We used a prespecified sampling frame to sample from the eligible studies, aiming to capture a range of respiratory infectious disease types, geographical spread and data-rich studies. We extracted data using a data extraction form designed for this synthesis. We assessed methodological limitations using an adapted version of the Critical Skills Appraisal Programme (CASP) tool. We used a 'best fit framework approach' to analyse and synthesise the evidence. This provided upfront analytical categories, with scope for further thematic analysis. We used the GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative research) approach to assess our confidence in each finding. We examined each review finding to identify factors that may influence intervention implementation and developed implications for practice. MAIN RESULTS: We found 36 relevant studies and sampled 20 of these studies for our analysis. Ten of these studies were from Asia, four from Africa, four from Central and North America and two from Australia. The studies explored the views and experiences of nurses, doctors and other healthcare workers when dealing with severe acute respiratory syndrome (SARS), H1N1, MERS (Middle East respiratory syndrome), tuberculosis (TB), or seasonal influenza. Most of these healthcare workers worked in hospitals; others worked in primary and community care settings. Our review points to several barriers and facilitators that influenced healthcare workers' ability to adhere to IPC guidelines. The following factors are based on findings assessed as of moderate to high confidence. Healthcare workers felt unsure as to how to adhere to local guidelines when they were long and ambiguous or did not reflect national or international guidelines. They could feel overwhelmed because local guidelines were constantly changing. They also described how IPC strategies led to increased workloads and fatigue, for instance because they had to use PPE and take on additional cleaning. Healthcare workers described how their responses to IPC guidelines were influenced by the level of support they felt that they received from their management team. Clear communication about IPC guidelines was seen as vital. But healthcare workers pointed to a lack of training about the infection itself and about how to use PPE. They also thought it was a problem when training was not mandatory. Sufficient space to isolate patients was also seen as vital. A lack of isolation rooms, anterooms and shower facilities was a problem. Other important practical measures described by healthcare workers included minimising overcrowding, fast-tracking infected patients, restricting visitors, and providing easy access to handwashing facilities. A lack of PPE, and equipment that was of poor quality, was a serious concern for healthcare workers and managers. They also pointed to the need to adjust the volume of supplies as infection outbreaks continued. Healthcare workers believed that they followed IPC guidance more closely when they saw the value of it. Some healthcare workers felt motivated to follow the guidance because of fear of infecting themselves or their families, or because they felt responsible for their patients. Some healthcare workers found it difficult to use masks and other equipment when it made patients feel isolated, frightened or stigmatised. Healthcare workers also found masks and other equipment uncomfortable to use. The workplace culture could also influence whether healthcare workers followed IPC guidelines or not. Across many of the findings, healthcare workers pointed to the importance of including all staff, including cleaning staff, porters, kitchen staff and other support staff when implementing IPC guidelines. AUTHORS' CONCLUSIONS: Healthcare workers point to several factors that influence their ability and willingness to follow IPC guidelines when managing respiratory infectious diseases. These include factors tied to the guideline itself and how it is communicated, support from managers, workplace culture, training, physical space, access to and trust in personal protective equipment, and a desire to deliver good patient care. The review also highlights the importance of including all facility staff, including support staff, when implementing IPC guidelines.

Factors influencing dietary behaviours in urban food environments in Africa: a systematic mapping review.

OBJECTIVE: To identify factors influencing dietary behaviours in urban food environments in Africa and identify areas for future research. DESIGN: We systematically reviewed published/grey literature (protocol CRD4201706893). Findings were compiled into a map using a socio-ecological model on four environmental levels: individual, social, physical and macro. SETTING: Urban food environments in Africa. PARTICIPANTS: Studies involving adolescents and adults (11-70 years, male/female). RESULTS: Thirty-nine studies were included (six adolescent, fifteen adolescent/adult combined and eighteen adult). Quantitative methods were most common (twenty-eight quantitative, nine qualitative and two mixed methods). Studies were from fifteen African countries. Seventy-seven factors influencing dietary behaviours were identified, with two-thirds at the individual level (45/77). Factors in the social (11/77), physical (12/77) and macro (9/77) environments were investigated less. Individual-level factors that specifically emerged for adolescents included self-esteem, body satisfaction, dieting, spoken language, school attendance, gender, body composition, pubertal development, BMI and fat mass. Studies involving adolescents investigated social environment-level factors more, for example, sharing food with friends. The physical food environment was more commonly explored in adults, for example, convenience/availability of food. Macro-level factors associated with dietary behaviours were food/drink advertising, religion and food prices. Factors associated with dietary behaviour were broadly similar for men and women. CONCLUSIONS: The dominance of studies exploring individual-level factors suggests a need for research to explore how social, physical and macro-level environments drive dietary behaviours of adolescents and adults in urban Africa. More studies are needed for adolescents and men, and studies widening the geographical scope to encompass all African countries.

Dietary behaviours in the context of nutrition transition: a systematic review and meta-analyses in two African countries.

OBJECTIVE: To synthesise evidence of urban dietary behaviours (macronutrients, types of foods, dietary diversity and dietary practices) in two African countries in relation to postulated changes in the context of nutrition transition. DESIGN: Systematic review and meta-analyses, including six online databases and grey literature, 1971-2018 (Protocol CRD42017067718). SETTING: Urban Ghana and Kenya. PARTICIPANTS: Population-based studies of healthy adolescents and adults. RESULTS: The forty-seven included studies encompassed 20 726 individuals plus 6526 households. Macronutrients were within WHO-recommended ranges: mean energy intake was 1867 kcal/d (95 % CI 1764, 1969) and the proportions of macronutrients were carbohydrate 61·2 % (58·4, 64·0), fat 25·3 % (22·8, 28·0) and protein 13·7 % (12·3, 15·1). The proportion of population consuming fruit and vegetables was 51·6 %; unhealthy foods, 29·4 %; and sugar-sweetened beverages (SSBs), 39·9 %. Two-thirds (68·8 %) consumed animal-source proteins. Dietary diversity scores were within the mid-range. Meal patterns were structured (typically three meals per day), with evidence lacking on snacking or eating out. CONCLUSIONS: Population-level diets fell within WHO macronutrient recommendations, were relatively diverse with structured meal patterns, but some indications of nutrition transition were apparent. The proportion of population consuming fruit and vegetables was low compared to healthy-eating recommendations, and consumption of SSBs was widespread. A paucity of evidence from 1971 to 2010 precluded a longitudinal analysis of nutrition transition. Evidence from these two countries indicates which aspects of dietary behaviours may be contributing to increasing overweight/obesity, namely a low proportion of population consuming fruit and vegetables and widespread consumption of SSBs. These are potential targets for promoting healthier diets.
