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.

In UK males, prostate cancer is the most common cancer, with over 47,500 diagnosed annually. Radiotherapy is a highly effective curative treatment but can be limited by dose to surrounding normal-tissues such as the rectum. Radiation to the rectum can be reduced by increasing the distance between prostate and rectum with a hydrogel spacer. Despite National Institute of Health and Care Excellence guidance, spacers are not widely funded in the UK. Limited funding has necessitated patient prioritization, without any existing consensus on method.

Studies have shown generally homogenous results in reduction of rectal toxicity across assessed subgroups, but the requirement to prioritize remains. One way of addressing the appropriate use of beneficial health technologies is the inclusion of end-user experts in decision-making. The study aim was to identify consensus among radiation oncologists on patient prioritization for rectal hydrogel spacers.

We conducted a Delphi study where six leading clinical oncologists and one urologist from across the UK experienced in using rectal hydrogel spacers participated in two rounds of online questionnaires and two virtual advisory board meetings.

The experts estimated that 83 percent of patients who could potentially benefit from a spacer were denied access. Overall, ten points of consensus were reached. Key ones concerning patient-access were:

• • Spacer use in eligible patients significantly reduces radiation dose to the rectum and toxicity-related adverse events.

• • Increased benefit is expected in patients on anticoagulation, with diabetes and with inflammatory bowel disease.

• • Increased benefit can be expected with ultra-hypofractionated radiotherapy, but radiotherapy modality is not a key consideration for patient selection.

• • Patients should have the opportunity to actively participate in the discussion regarding the use of a spacer.

Currently, not all patients who would benefit can access funding for hydrogel spacers. Consensus in this study indicates that appropriate health policy and funding mechanisms are warranted for patients, to provide equitable access to technologies improving quality of life.

Cognitive dispersion across neuropsychological measures within a single testing session is a promising marker predictive of cognitive decline and development of Alzheimer’s disease (AD). However, little is known regarding brain changes underlying cognitive dispersion, and the association of cognitive dispersion with in vivo AD biomarkers and regional cerebral blood flow (CBF) has received limited study. We therefore examined associations among cognitive dispersion, amyloid-beta (Aβ) positivity, and regional CBF among older adults free of dementia.

One hundred and forty-eight Alzheimer’s Disease Neuroimaging Initiative (ADNI) participants underwent neuropsychological testing and neuroimaging. Pulsed arterial spin labeling (ASL) magnetic resonance imaging (MRI) was acquired to quantify CBF. Florbetapir positron emission tomography (PET) imaging determined Aβ positivity.

Adjusting for age, gender, education, and mean cognitive performance, older adults who were Aβ+ showed higher cognitive dispersion relative to those who were Aβ-. Across the entire sample, higher cognitive dispersion was associated with reduced CBF in inferior parietal and temporal regions. Secondary analyses stratified by Aβ status demonstrated that higher cognitive dispersion was associated with reduced CBF among Aβ+ individuals but not among those who were Aβ-.

Cognitive dispersion may be sensitive to early Aβ accumulation and cerebrovascular changes adjusting for demographics and mean neuropsychological performance. Associations between cognitive dispersion and CBF were observed among Aβ+ individuals, suggesting that cognitive dispersion may be a marker of brain changes among individuals on the AD continuum. Future studies should examine whether cognitive dispersion predicts brain changes in diverse samples and among those with greater vascular risk burden.

Homosexuality was declassified as a mental illness in 1973 however LGBTQ+ (lesbian, gay, bisexual, transgender, queer inclusive) service users still face discrimination within modern mental health services. This project assessed homophobia and LGBTQ+ abuse among service users on an acute male psychiatric ward. Our aims were to quantify the incidence of abuse, to explore staff attitudes toward LGBTQ+ abuse and to identify targets to improve LGBTQ+ service users’ experience. We hypothesised that incidents of abuse are common and not always challenged or escalated using appropriate channels.

Using a mixed methods approach we explored staff perceptions of LGBT+ abuse: quantitative data were generated from a questionnaire survey and qualitative data from a focus group.

Rates of homophobic incidents were assessed by analysing clinical documentation from two inpatient samples (n = 20), covering 2020–21 and 2021–22.

Analysis of clinical documentation found three incidents from the 2020–21 sample and two from 2021–22; only one of these was reported via DATIX.

The survey captured the views of the ward team including nurses, healthcare assistants (HCAs), doctors and psychologists (response n = 13). Staff attitudes towards LGBTQ+ were rated as “positive” by 77% of responders and “neutral” by 23%; 100% stated it was their professional duty to respect and protect LGBTQ+ clients. Almost two-thirds (62%) had witnessed homophobia on the ward however a similar proportion (61%) had never directly challenged homophobia. Whilst all staff felt able to care for LGBTQ+ clients, and all were familiar with key LGBTQ+ terminology, only 50% felt they had received adequate training to fully support LGBTQ+ clients.

The focus group identified a nursing “lead” for LGBTQ+ issues and agreed to incorporate a “diversity statement” into ward admission rules. LGBTQ+ visibility measures were promoted including LGBTQ+ posters across the ward and staff uptake of the Rainbow Badge Initiative.

Our findings suggest homophobia is prevalent in the male inpatient psychiatric setting and management is suboptimal. Enhanced LGBTQ+ training is required to support staff to challenge every homophobic incident and escalate appropriately.

Simple steps to increase LGBTQ+ visibility are feasible and popular among staff. Future work should assess the impact of such interventions, however measuring change may be hampered by underreporting.

Further evaluations are needed to assess female wards and patient perspectives to build a full picture of inpatient LGBTQ+ abuse.

To examine differences in surgical practices between salaried and fee-for-service (FFS) surgeons for two common degenerative spine conditions. Surgeons may offer different treatments for similar conditions on the basis of their compensation mechanism.

The study assessed the practices of 63 spine surgeons across eight Canadian provinces (39 FFS surgeons and 24 salaried) who performed surgery for two lumbar conditions: stable spinal stenosis and degenerative spondylolisthesis. The study included a multicenter, ambispective review of consecutive spine surgery patients enrolled in the Canadian Spine Outcomes and Research Network registry between October 2012 and July 2018. The primary outcome was the difference in type of procedures performed between the two groups. Secondary study variables included surgical characteristics, baseline patient factors, and patient-reported outcome.

For stable spinal stenosis (n = 2234), salaried surgeons performed statistically fewer uninstrumented fusion (p < 0.05) than FFS surgeons. For degenerative spondylolisthesis (n = 1292), salaried surgeons performed significantly more instrumentation plus interbody fusions (p < 0.05). There were no statistical differences in patient-reported outcomes between the two groups.

Surgeon compensation was associated with different approaches to stable lumbar spinal stenosis and degenerative lumbar spondylolisthesis. Salaried surgeons chose a more conservative approach to spinal stenosis and a more aggressive approach to degenerative spondylolisthesis, which highlights that remuneration is likely a minor determinant in the differences in practice of spinal surgery in Canada. Further research is needed to further elucidate which variables, other than patient demographics and financial incentives, influence surgical decision-making.

Multiple sclerosis (MS) is a debilitating neurological disease associated with a variety of psychological, cognitive, and motoric symptoms. Walking is among the most important functions compromised by MS. Dual-task walking (DTW), an everyday activity in which people walk and engage in a concurrent, discrete task, has been assessed in MS, but little is known about how it relates to other MS symptoms. Self-awareness theory suggests that DTW may be a function of the interactions among psychological, cognitive, and motor processes.

Cognitive testing, self-report assessments for depression and falls self-efficacy (FSE), and walk evaluations [DTW and single-task walk (STW)] were assessed in seventy-three people with MS in a clinical care setting. Specifically, we assessed whether psychological factors (depression and FSE) that alter subjective evaluations regarding one’s abilities would moderate the relationships between physical and cognitive abilities and DTW performance.

DTW speed is related to diverse physical and cognitive predictors. In support of self-awareness theory, FSE moderated the relationship between STW and DTW speeds such that lower FSE attenuated the strength of the relationship between them. DTW costs – the change in speed normalized by STW speed – did not relate to cognitive and motor predictors. DTW costs did relate to depressive symptoms, and depressive symptoms moderated the effect of information processing on DTW costs.

Findings indicate that an interplay of physical ability and psychological factors – like depression and FSE – may enhance understanding of walking performance under complex, real-world, DTW contexts.

As clinical trials were rapidly initiated in response to the COVID-19 pandemic, Data and Safety Monitoring Boards (DSMBs) faced unique challenges overseeing trials of therapies never tested in a disease not yet characterized. Traditionally, individual DSMBs do not interact or have the benefit of seeing data from other accruing trials for an aggregated analysis to meaningfully interpret safety signals of similar therapeutics. In response, we developed a compliant DSMB Coordination (DSMBc) framework to allow the DSMB from one study investigating the use of SARS-CoV-2 convalescent plasma to treat COVID-19 to review data from similar ongoing studies for the purpose of safety monitoring.

The DSMBc process included engagement of DSMB chairs and board members, execution of contractual agreements, secure data acquisition, generation of harmonized reports utilizing statistical graphics, and secure report sharing with DSMB members. Detailed process maps, a secure portal for managing DSMB reports, and templates for data sharing and confidentiality agreements were developed.

Four trials participated. Data from one trial were successfully harmonized with that of an ongoing trial. Harmonized reports allowing for visualization and drill down into the data were presented to the ongoing trial’s DSMB. While DSMB deliberations are confidential, the Chair confirmed successful review of the harmonized report.

It is feasible to coordinate DSMB reviews of multiple independent studies of a similar therapeutic in similar patient cohorts. The materials presented mitigate challenges to DSMBc and will help expand these initiatives so DSMBs may make more informed decisions with all available information.

Optimizing needleless connector hub disinfection practice is a key strategy in central-line–associated bloodstream infection (CLABSI) prevention. In this mixed-methods evaluation, 3 products with varying scrub times were tested for experimental disinfection followed by a qualitative nursing assessment of each.

Needleless connectors were inoculated with varying concentrations of Staphylococcus epidermidis, Pseudomonas aeruginosa, and Staphylococcus aureus followed by disinfection with a 70% isopropyl alcohol (IPA) wipe (a 15-second scrub time and a 15-second dry time), a 70% IPA cap (a 10-second scrub time and a 5-second dry time), or a 3.15% chlorhexidine gluconate with 70% IPA (CHG/IPA) wipe (a 5-second scrub time and a 5-second dry time). Cultures of needleless connectors were obtained after disinfection to quantify bacterial reduction. This was followed by surveying a convenience sample of nursing staff with intensive care unit assignments at an academic tertiary hospital on use of each product.

All products reduced overall bacterial burden when compared to sterile water controls, however the IPA and CHG/IPA wipes were superior to the IPA caps when product efficacy was compared. Nursing staff noted improved compliance with CHG/IPA wipes compared with the IPA wipes and the IPA caps, with many preferring the lesser scrub and dry times required for disinfection.

Achieving adequate bacterial disinfection of needleless connectors while maximizing healthcare staff compliance with scrub and dry times may be best achieved with a combination CHG/IPA wipe.

Although recent reports suggest that service users in West African psychiatric facilities are exposed to poor quality of care and human rights violations, evidence is lacking on the extent and profile of specific deficits in the services provided to persons with mental health conditions.

To evaluate the quality of care and respect of human rights in psychiatric facilities in four West African countries, The Gambia, Ghana, Liberia and Sierra Leone, using the World Health Organization QualityRights Toolkit.

Trained research workers collected information through observation, review of records and interviews with service users, caregivers and staff. Independent panels of assessors used the information to assign scores to the criteria, standards and themes of the QualityRights Toolkit.

The study revealed significant gaps in these facilities. The rights to an adequate standard of living and to enjoyment of the highest attainable standard of health were poorly promoted. Adherence to the right to exercise legal capacity and the right to personal liberty and security was almost absent. Severe shortcomings in the promotion of the right to live independently and be included in the community were reported.

Inadequate appreciation of service users’ rights, lack of basic approaches to protect them and the non-promotion of rights-based services in these facilities are major problems that need to be addressed. Although it recognises the resource constraints and need for more human and financial resources, the study also identifies critical areas and challenges that require significant changes at the facility level.

This report examines between- and within-person associations between youth irritability and concurrent and prospective internalizing and externalizing symptoms from early childhood through adolescence. Distinguishing between- and within-person longitudinal associations may yield distinct, clinically relevant information about pathways to multifinality from childhood irritability.

Children’s irritability and co-occurring symptoms were assessed across five waves between ages 3 and 15 years using the mother-reported Child Behavior Checklist (N = 605, 46% female). Parental history of depressive disorders was assessed with a clinical interview.

Results demonstrated that between- and within-person irritability were uniquely associated with concurrent depressive, anxiety, and defiance symptoms, but not ADHD. Prior wave within-person irritability also predicted next wave depressive, anxiety, and defiance symptoms, controlling for prior symptoms; these prospective associations were bidirectional. Child sex and parental depressive disorders moderated associations.

Findings identify pathways from within- and between-person irritability to later internalizing and externalizing psychopathology. Results demonstrate the importance of parsing within- and between-person effects to understand nuanced relations among symptoms over childhood.
