Outcomes of Visceral Arterial Reconstruction: A Systematic Review
Aims: The study aimed to review the use of synthetic grafts (SGs) and autologous vein grafts (AVGs) in visceral arterial reconstruction (VAR) in chronic visceral ischaemia.
Methods: Systematic review methodology was employed.
Results: Six studies were included (218 patients and 281 vessels). Two studies had data about AVG only, 3 had data about SG only and 1 had both AVG and SG data. Three studies reported outcomes for AVG (117 patients and 132 vessels revascularized). One-year primary patency was 87% (95% CI 71%, 97%). Graft thrombosis rate was 6% (95% CI 0%, 16%). Pooled stenosis rate at one-year was 11% (95% CI 1%, 28%). The 30-day (n = 96), one-year (n = 72) and 5-year mortality (n = 30) were 0%, 0% and 12%, respectively. Four studies reported outcomes for SGs (106 patients and 147 vessels). The pooled primary patency at one year was 100% (95% CI 99%, 100%). Pooled primary 5-year patency rate was 88% (95% CI 69%, 100%). There was no graft infection in 2 of the 3 studies. Overall pooled percentage of graft thrombosis and stenosis at one year was 0%. Jimenez et al. (2002) reported one graft thrombosis at 20 months and graft stenosis in 2 patients at 46 and 49 months. Illuminati et al (2017) reported graft thrombosis in 2/24 patients at 22 and 52 months. Thirty days, one-year and 5-year mortality was 1% (95% CI 0%, 6), 7% (95% CI 0%, 20%) and 39% (95% CI 11%), respectively.
Conclusion: Patency was better with SG compared with AVG. Mortality was higher in the SG group. Graft dilatation does occur with vein grafts, but in this review no intervention was found necessary. Poorly designed studies, incomplete reporting and absence of morbidity and mortality indices preclude emphatic conclusions
Research and effectiveness of interreligious dialogue and ecumenism interventions: Systematic evidence gap map and synthesis
Indigenising systematic reviews with a collaborative model of ‘training the trainers’
Background: Developing a workforce with the skills to produce and make judicious use of evidence for policy and practice decisions requires trainers who can tailor evidence and training to policy and practice priorities.
//
Aim: To describe how a collaborative learning model adapted a systematic review course to suit Indian nurse educators and research scholars in the conduct and use of systematic reviews.
//
Discussion: A collaborative learning team of academics and research scholars brought together expertise in nursing education in India, and evidence synthesis in India and the UK. Participants found the course was highly beneficial, enhanced independent and critical thinking, and instilled them with the confidence and skills to deliver such courses to Indian researchers, nurses and other healthcare professionals.
//
Conclusion: Contextualising materials and methods to participants’ experiences made learning more relatable. The use of adult learning approaches enabled participants to apply the same approaches when leading training in their own institutions and underpinned long-term sustainable working relationships between facilitators and learners, leading to new studies and new resources to support evidence-informed decision-making.
//
Implications for practice: An educational intervention on ‘indigenising systematic reviews’ with online collaborative learning can produce improvements in the knowledge and skills of participants. Advantages of this educational approach include its flexibility, active involvement of participants and sustainable partnership building. The principles and methods used could be replicated in any setting to train trainers
Effectiveness of an Evidence-Based Practice Training Program for Nurse Educators: A Cluster-Randomized Controlled Trial
BACKGROUND: Evidence-based practice (EBP) endeavors to integrate the best available evidence with clinical expertise and patient preference to enhance clinical outcomes. For nurses to effectively demonstrate EBP, the concepts of EBP should be systematically incorporated into the nursing curriculum, with nurse educators playing a pivotal role in execution. However, the effect of EBP training programs on nurse educators remains largely unexplored. AIM: To evaluate the effectiveness of an EBP training program on the knowledge, attitude, practice, and competency of nurse educators. METHODS: A pragmatic randomized controlled trial was conducted at a nursing education institution. Fifty-one nurse educators were cluster randomized into intervention and control groups. A 30-hour EBP training intervention was provided for nurse educators in the intervention group. The outcome variables were knowledge, attitude, practice, and competency regarding EBP. These outcomes were evaluated using the EBP knowledge and practice questionnaire, EBP attitude scale, and Fresno test. Data were collected at baseline, the end of 5 months, and the end of 10 months. RESULTS: Fifty-one eligible participants were enrolled in the study. The intervention and control group had three clusters each with 27 and 24 participants, respectively. Participants in both groups were comparable for variables such as age, years of experience, and educational background (p > .05). Between groups, outcome variables were compared using mixed linear multi-level modeling. Nurse educators who received the EBP training program demonstrated significant differences in knowledge (p < .05), attitude (p < .05), practice (p < .05), and competency scores (p < .05), than that of the control group, indicating the intervention effectiveness. LINKING EVIDENCE TO ACTION: EBP training programs are effective in improving the knowledge, attitude, practice, and competency of nurse educators
Digital interventions in alcohol and drug prevention, treatment and recovery: Systematic maps of international research and interventions available in England
Executive Summary
Background
Digital interventions in alcohol and drug prevention, treatment and recovery have the
potential to overcome barriers faced by non-digital interventions. However, we lack a
clear understanding of the types of digital interventions that have been evaluated and
where gaps in the evidence base exist. We also need to understand the effectiveness of
different types of digital alcohol and drug interventions for various population groups.
Further, we do not know which digital alcohol and drug interventions are being used
in England, and whether the interventions in use align with those that have been
evaluated.
Research questions
To address the above concerns, we sought to address the following questions:
• RQ1: What is the possible range of digital alcohol and drug interventions?
• RQ2: Which types of digital alcohol and drug interventions are currently
available for use in England?
• RQ3: What systematic reviews provide findings for digital alcohol and drug
intervention strategies within a prevention/treatment/recovery pathway?
• RQ4: Which types of digital alcohol and drug interventions have been evaluated
in primary research?
• RQ5: To what extent does the evaluation evidence overlap with digital alcohol
and drug interventions that are currently available for use in England?
• RQ6: What evidence is there that certain types of digital alcohol and drug
interventions are (cost-) effective or ineffective for specific population groups
or in particular contexts?
This report covers our findings in relation to questions RQ1 - RQ5. Based on these
findings we also provide suggestions as to what could be the focus of further work to
answer RQ6.
Methods
To address RQ1 an initial typology was drafted, adapting and building on existing
typologies of digital interventions. Through this process it became clear to OHID/PHE
that a pathway, presenting a route through services, with different types of
interventions recommended for use at different times would be more helpful than a
typology of intervention characteristics. This pathway was then developed by OHID/PHE and trialled by the research team, with refinements made over time with
discussions between the study team and PHE.
To address RQ2 we contacted people in England in 2019, who were involved in
developing, commissioning, prescribing, recommending or evaluating digital
alcohol/drug interventions. Using an online survey, we asked them to describe the
interventions they were involved with.
To address RQ3, RQ4 and RQ5 we conducted systematic searching and screening to
identify and describe existing systematic reviews (RQ3) and primary studies (RQ4).
Included systematic reviews were appraised for quality and detailed information was
extracted from full reports. For primary studies we extracted basic details using the
information contained within the title and abstract.
The pathway developed for RQ1 was employed to code and describe the nature of
available interventions (RQ2), systematic reviews (RQ3) and primary studies (RQ4).
EPPI-Mapper software was used to produce online interactive maps to visually display
the findings
Interventions to support contraceptive choice and use: a global systematic map of systematic reviews
BACKGROUND: To review the highest level of available evidence, a systematic map identified systematic reviews that evaluated the effectiveness of interventions to improve contraception choice and increase contraception use. METHODS: Systematic reviews published since 2000 were identified from searches of nine databases. Data were extracted using a coding tool developed for this systematic map. Methodological quality of included reviews was assessed using AMSTAR 2 criteria. FINDINGS AND CONCLUSION: Fifty systematic reviews reported evaluations of interventions for contraception choice and use addressing three domains (individual, couples, community); Meta-analyses in 11 of the reviews mostly addressed interventions for individuals. We identified 26 reviews covering High Income Countries, 12 reviews covering Low Middle-Income Countries and the rest a mix of both. Most reviews (15) focussed on psychosocial interventions, followed by incentives (6) and m-health interventions (6). The strongest evidence from meta-analyses is for the effectiveness of motivational interviewing, contraceptive counselling, psychosocial interventions, school-based education, and interventions promoting contraceptive access, demand-generation interventions (community and facility based, financial mechanisms and mass media), and mobile phone message interventions. Even in resource constrained settings, community-based interventions can increase contraceptive use. There are gaps in the evidence on interventions for contraception choice and use, and limitations in study designs and lack of representativeness. Most approaches focus on individual women rather than couples or wider socio-cultural influences on contraception and fertility. This review identifies interventions which work to increase contraception choice and use, and these could be implemented in school, healthcare or community settings
The utilisation of systematic review evidence in formulating India's National Health Programme guidelines between 2007 to 2021
Evidence informed policymaking integrates the best available evidence on programme outcomes to guide decisions at all stages of the policy process and its importance becomes more pronounced in resource constrained settings. In this paper, we have reviewed the use of systematic review evidence in framing National Health Programme (NHP) guidelines in India. We searched official websites of the different NHPs, linked to the main website of the Ministry of Health and Family Welfare (MoHFW), in December 2020 and January 2021. NHP guideline documents with systematic review evidence were identified and information on the use of this evidence was extracted. We classified the identified systematic review evidence according to its use in the guideline documents and analysed the data to provide information on the different factors and patterns linked to the use of systematic review evidence in these documents. Systematic reviews were mostly visible in guideline documents addressing maternal and newborn health, communicable diseases and immunization. These systematic reviews were cited in the guidelines to justify the need for action, to justify recommendations for action and opportunities for local adaptation; and to highlight implementation challenges and justify implementation strategies. Guideline documents addressing implementation cited systematic reviews about the problems and policy options more often than citing systematic reviews about implementation. Systematic reviews were linked directly to support statements in few guideline documents, and sometimes the reviews were not appropriately cited. Most of the systematic reviews providing information on the nature and scale of the policy problem included Indian data. It was seen that since 2014, India has been increasingly using systematic review evidence for public health policymaking particularly for some of its high priority NHPs. This complements the increasing investment in research synthesis centres and procedures to support evidence informed decision making, demonstrating the continued evolution of India's evidence policy system
How do you develop a career at the policy-research interface?
Context: Careers at the policy-research interface may be ill-defined and require reframing of identity, depending on context and purpose. We wanted to explore this further as part of our involvement with the Partnership for Evidence and Equity in Responsive Social Systems (PEERSS) - a global partnership working to advance the use of evidence for progress in social systems. /
Aim: To share and prompt thinking about the skills, opportunities and barriers of such careers. /
Method: We iteratively develop themes informed by ecological theoretical frameworks, literature on policy-research interface, group discussion, and autoethnographies of people at a range of career stages and backgrounds. We invite participants to contribute their own views via a Padlet platform. /
Results and discussion: We highlight some of the individual attitudes and behaviours, socio-demographic factors, immediate environment, and wider context shaping early career development. /
Conclusions: While it may be challenging to distinguish specific themes from influences that may apply to other career trajectories, the emerging narrative generated provide useful and important insights for those wanting to develop roles in this area
Using automation to produce a ‘living map’ of the COVID-19 research literature
The COVID-19 pandemic has disrupted life worldwide and presented unique challenges in the health evidencesynthesis space. The urgent nature of the pandemic required extreme rapidity for keeping track of research, andthis presented a unique opportunity for long-proposed automation systems to be deployed and evaluated. Wecompared the use of novel automation technologies with conventional manual screening; and Microsoft AcademicGraph (MAG) with the MEDLINE and Embase databases locating the emerging research evidence. We foundthat a new workflow involving machine learning to identify relevant research in MAG achieved a much higherrecall with lower manual effort than using conventional approaches
Cost-effectiveness of Microsoft Academic Graph with machine learning for automated study identification in a living map of coronavirus disease 2019 (COVID-19) research
Background: Identifying new, eligible studies for integration into living systematic reviews and maps usually relies on conventional Boolean updating searches of multiple databases and manual processing of the updated results. Automated searches of one, comprehensive, continuously updated source, with adjunctive machine learning, could enable more efficient searching, selection and prioritisation workflows for updating (living) reviews and maps, though research is needed to establish this. Microsoft Academic Graph (MAG) is a potentially comprehensive single source which also contains metadata that can be used in machine learning to help efficiently identify eligible studies. This study sought to establish whether: (a) MAG was a sufficiently sensitive single source to maintain our living map of COVID-19 research; and (b) eligible records could be identified with an acceptably high level of specificity. Methods: We conducted an eight-arm cost-effectiveness analysis to assess the costs, recall and precision of semi-automated workflows, incorporating MAG with adjunctive machine learning, for continually updating our living map. Resource use data (time use) were collected from information specialists and other researchers involved in map production. Our systematic review software, EPPI-Reviewer, was adapted to incorporate MAG and associated machine learning workflows, and also used to collect data on recall, precision, and manual screening workload. Results: The semi-automated MAG-enabled workflow dominated conventional workflows in both the base case and sensitivity analyses. At one month our MAG-enabled workflow with machine learning, active learning and fixed screening targets identified 469 additional, eligible articles for inclusion in our living map, and cost £3,179 GBP per week less, compared with conventional methods relying on Boolean searches of Medline and Embase. Conclusions: We were able to increase recall and coverage of a large living map, whilst reducing its production costs. This finding is likely to be transferrable to OpenAlex, MAG’s successor database platform
