Since the vaccine roll out, research has focused on vaccine safety and efficacy, with large clinical trials confirming that vaccines are generally effective against symptomatic COVID-19 infection. However, breakthrough infections can still occur, and the effectiveness of vaccines against transmission from infected vaccinated people to susceptible contacts is unclear.

Health Technology Wales (HTW) collaborated with the Wales COVID-19 Evidence Centre to identify and examine evidence on the transmission risk of SARS-CoV-2 from vaccinated people to unvaccinated or vaccinated people.

We conducted a systematic literature search for evidence on vaccinated people exposed to SARS-CoV-2 in any setting. Outcome measures included transmission rate, cycle threshold (Ct) values and viral load. We identified a rapid review by the University of Calgary that was the main source of our outcome data. Nine studies published following the rapid review were also identified and included.

In total, 35 studies were included in this review: one randomized controlled trial (RCT), one post-hoc analysis of an RCT, 13 prospective cohort studies, 16 retrospective cohort studies and four case control studies.

All studies reported a reduction in transmission of the B.1.1.7 (Alpha) variant from partial and fully vaccinated individuals. More recent evidence is uncertain on the effects of vaccination on transmission of the B.1.617.2 (Delta) variant. Overall, vaccine effectiveness in reducing transmission appears to increase with full vaccination, compared with partial vaccination. Most of the direct evidence is limited to transmission in household settings therefore, there is a gap in the evidence on risk of transmission in other settings. One UK study found protection against onward transmission waned within 3 months post second vaccination.

Early findings that focused on the alpha variant, showed a reduction in transmission from vaccinated people. There is limited evidence on the effectiveness of vaccination on transmission of the Delta variant, therefore alternative preventative measures to reduce transmission may still be required.

At various stages of the COVID-19 pandemic, face coverings have been recommended and encouraged as one of the interventions to reduce transmission of the SARS-CoV-2 virus. However, in the earlier stages of the pandemic, decisions on face coverings relied primarily on evidence based on other viral respiratory infections. More direct evidence on the use of face coverings with COVID-19 developed in tandem with the pandemic.

Health Technology Wales undertook an ultra-rapid review to inform national guidelines, the work assessed the evidence on the effectiveness of face coverings to reduce SARS-CoV-2 transmission. We also reviewed evidence on the efficacy of different types of face coverings.

We conducted a systematic literature search for evidence to address (i) the effectiveness of face coverings to reduce the spread of COVID-19 in the community, and (ii) the efficacy of different types of face coverings designed for use in community settings. We identified a rapid review in 2021 by Public Health England that closely aligned with our review questions. This provided the main source for identifying relevant studies, supplemented by a search for publications following their search date.

We identified two evidence reviews (including the Public Health England review) that examined the effectiveness of face coverings on reducing transmission of SARS-CoV-2; reporting on 31 and 39 studies, respectively. Two further primary studies were published after the two evidence review searches were included. Overall, the evidence suggested that face coverings may provide benefits in preventing SARS-CoV-2 transmission, although the higher-quality studies suggested that these benefits may be modest. Medical masks appeared to have higher efficacy than fabric masks, although the evidence was mixed.

At the time of this review, evidence on the effectiveness of face coverings remains limited and conclusions rely on low-quality sources of evidence with high risk of bias, although higher-quality evidence points to some benefit. Face coverings may play a role in preventing transmission of SARS-CoV-2, particularly as part of a bundle of other preventative measures.

The COVID-19 pandemic has had a dramatic impact on the health and social care landscape, both in terms of service provision and citizen need. Responsive, evidence-based research is essential to develop and implement appropriate policies and practices that manage both the pandemic itself, and the impact COVID-19 has on other health and social care issues.

To address this, the Wales COVID-19 Evidence Centre (WCEC) was launched in 2021 with the aim of providing the best available, up-to-date, and relevant evidence to inform health and care decision making across Wales.

Funded by the Welsh Government, the WCEC comprises of a core team and several collaborating partner organizations, including Health Technology Wales, Wales Centre for Evidence-Based Care, Specialist Unit for Review Evidence Centre, SAIL Databank, Public Health Wales, Bangor Institute for Health & Medical Research in conjunction with Health and Care Economics Cymru, and the Public Health Wales Observatory. Over the last year, WCEC has developed its rapid review processes and methodology informed by best international practice and aims to provide around 50 reviews each year. WCEC works alongside various stakeholder groups from health and social care across Wales, and they form an integral part of the review process, from scoping to knowledge mobilization.

To date, the WCEC has produced reviews on a diverse range of COVID-19 topics, including transmission, vaccination uptake (barriers, facilitators and interventions), mental health and wellbeing, as well as face coverings and other preventative interventions. The topics have also covered a wide range of populations, from general public, to healthcare workers, to children. These reviews have been used to inform policy and decision-making, including the Welsh Government’s Chief Medical Officer 21-day COVID-19 reviews.

The WCEC has brought together multiple specialist centers with a diverse range of skills to produce timely reviews of the most up-to-date research to support decision makers across health and social care. These reviews have informed policy and decision-making across Wales.

Health Technology Wales (HTW) review guidance 3 years after publication to establish if reassessment is warranted because, for example, new evidence has become available. Since the publication of guidance on flash glucose monitoring (FGM) in 2018, HTW introduced a patient and public involvement (PPI) process with novel approaches to flexible engagement. This enabled HTW to include three streams of patient evidence into the review of FGM devices.

HTW’s Patient and Public Involvement Standing Group (PPISG) considered appropriate methods of engagement using the HTW Patient and Public Involvement Mechanism Tool. This tool considers the nature of the health technology, the presence of appropriate patient organizations and questions that can be put to patients, as well as other approaches for obtaining patient evidence.

HTW contacted Diabetes Cymru and met with them to discuss contributing to the appraisal of FGM devices. Diabetes Cymru produced a patient submission summarizing the experiences of their patient network, with particular focus on the expansion of the technology to closed-loop insulin systems. Diabetes Cymru later attended HTW’s Appraisal Panel committee and gave a presentation. Additionally, HTW conducted a patient evidence literature review. This review summarized published qualitative studies on a range of perspectives, including carer perspectives, family perspectives, children and adolescences perspectives as well as considerations from specific environments, such as schools, workplaces, homes, care homes and communities. In addition to new clinical and cost effectiveness evidence, this PPI input was used to formulate new guidance recommending more widespread adoption of FGM.

The introduction of flexible approaches to PPI enabled HTW to gain patient evidence from multiple sources. This ensured greater patient representation and a more detailed understanding of the role of FGM devices across different patient communities. This added considerable richness to the patient evidence, which is vital to understand the everyday impacts of FGM and its use amongst patients. Combining flexible PPI with the new clinical and cost effectiveness evidence resulted in a change in the original guidance recommendation.

Spiritual care is a component of quality palliative care, but healthcare providers have reported lack of training as a barrier to its provision. This paper describes the evaluation of the Interprofessional Spiritual Care Educational Curriculum (ISPEC)© which is a six-module evidence-based curriculum developed for teaching interprofessional spiritual care based on a generalist-specialist model of spiritual care.

The course was run online in 2020 and attended by 20 healthcare workers who were invited to join the evaluation. Questionnaires were completed by participants before the training program (baseline), immediately after the training (post), and 3 months following the end of the program (follow-up). After the follow-up questionnaires, participants were invited to join a Focus Group to expand on their responses. Descriptive and exploratory statistical analysis was performed on quantitative data, and qualitative data was subjected to Thematic Analysis.

Exploratory data analysis showed that self-reported competence, confidence, and comfort in providing spiritual care significantly improved following training (p = 0.002) and were maintained over time (p = 0.034). In qualitative analysis, the main themes were: (1) overwhelmed by content; (2) the importance of practical training; (3) spiritual care is for everyone; (4) spiritual care should come from the heart; (5) training needs to be inclusive; and (6) spirituality is culturally specific.

This article describes an evaluation of the ISPEC© spiritual care training course administered to an Australian healthcare cohort using an online format. These preliminary findings suggest that the ISPEC© program is effective in improving the ability of healthcare professionals to provide spiritual care. More work is needed to improve the cultural relevance of the program in Australia.
