Methodology for the Positive Voices 2022 Survey of People With HIV Accessing Care in England, Wales, and Scotland: Cross-Sectional Questionnaire Study.

Background: Due to advances in treatment, HIV is now a chronic condition with near-normal life expectancy. However, people with HIV continue to have a higher burden of mental and physical health conditions and are impacted by wider socioeconomic issues. Positive Voices is a nationally representative series of surveys of people with HIV in the United Kingdom.

COVID-19 Vaccine Safety in Pregnancy, A Nested Case-Control Study in Births From April 2021 to March 2022, England.

Objective: Assessment of COVID-19 vaccine safety in pregnancy using population-based data.

Design: Matched case-control study nested in a retrospective cohort.

Setting: April 2021-March 2022, England.

Estimated number of lives directly saved by COVID-19 vaccination programmes in the WHO European Region from December, 2020, to March, 2023: a retrospective surveillance study.

Background: By March, 2023, 54 countries, areas, and territories (hereafter CAT) in the WHO European Region had reported more than 2·2 million COVID-19-related deaths to the WHO Regional Office for Europe. Here, we estimated how many lives were directly saved by vaccinating adults in the WHO European Region from December, 2020, to March, 2023.

Methods: In this retrospective surveillance study, we estimated the number of lives directly saved by age group, vaccine dose, and circulating variant-of-concern (VOC) period, regionally and nationally, using weekly data on COVID-19 mortality and infection, COVID-19 vaccination uptake, and SARS-CoV-2 virus characterisations by lineage downloaded from The European Surveillance System on June 11, 2023, as well as vaccine effectiveness data from the literature.

HIV-related Stigma and Discrimination in Health Care and Health-related Quality of Life among People Living with HIV in England and Wales: A Latent Class Analysis.

Though life expectancy of people living with HIV (PLHIV) is now comparable to that of HIV-negative persons, their health-related quality of life (HRQoL) lags behind. Lower HRQoL among PLHIV may vary meaningfully, shaped in part by social factors, including stigma. Using data from Positive Voices, a national cross-sectional probability survey of adults ≥ 18 years living with HIV and accessing HIV care services in England and Wales ( = 4,422), we conducted latent class analysis on responses to a HRQoL measure (problems with mobility, usual activities, self-care, pain/discomfort, anxiety/depression) to identify HRQoL patterns, followed by multinomial logistic regression to examine relationships between HRQoL classes and a 4-item measure of HIV-related stigma and discrimination in health care.

Vaccine effectiveness against hospitalisation estimated using a test-negative case-control study design, and comparative odds of hospital admission and severe outcomes with COVID-19 sub-lineages BQ.1, CH.1.1. and XBB.1.5 in England.

Background: Since the first emergence of Omicron BA.1 in England in November 2021, numerous sub-lineages have evolved. In September 2022, BA.

Temporal changes to adult case fatality risk of COVID-19 after vaccination in England between May 2020 and February 2022: a national surveillance study.

Objectives: Risk of death after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has fallen during the pandemic, largely due to immunity from vaccination. In England, the timing and extent of this reduction varied due to staggered eligibility during the primary vaccination campaign, based on age and clinical risk group. Duration of protection is less well understood.

Genomic assessment of invasion dynamics of SARS-CoV-2 Omicron BA.1.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern (VOCs) now arise in the context of heterogeneous human connectivity and population immunity. Through a large-scale phylodynamic analysis of 115,622 Omicron BA.1 genomes, we identified >6,000 introductions of the antigenically distinct VOC into England and analyzed their local transmission and dispersal history.

Comparative transmission of SARS-CoV-2 Omicron (B.1.1.529) and Delta (B.1.617.2) variants and the impact of vaccination: national cohort study, England.

COVID-19 deaths in children and young people in England, March 2020 to December 2021: An active prospective national surveillance study.

Background: Coronavirus Disease 2019 (COVID-19) deaths are rare in children and young people (CYP). The high rates of asymptomatic and mild infections complicate assessment of cause of death in CYP. We assessed the cause of death in all CYP with a positive Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) test since the start of the pandemic in England.

Parents' and teachers' attitudes to and experiences of the implementation of COVID-19 preventive measures in primary and secondary schools following reopening of schools in autumn 2020: a descriptive cross-sectional survey.

Objective: To assess implementation and ease of implementation of control measures in schools as reported by staff and parents.

Design: A descriptive cross-sectional survey.

Setting: Staff and parents/guardians of the 132 primary schools and 19 secondary schools participating in COVID-19 surveillance in school kids (sKIDs and sKIDsPLUS Studies).

Nowcasting COVID-19 deaths in England by age and region.

Understanding the trajectory of the daily number of COVID-19 deaths is essential to decisions on how to respond to the pandemic, but estimating this trajectory is complicated by the delay between deaths occurring and being reported. In England the delay is typically several days, but it can be weeks. This causes considerable uncertainty about how many deaths occurred in recent days.

Assessment of mortality and hospital admissions associated with confirmed infection with SARS-CoV-2 Alpha variant: a matched cohort and time-to-event analysis, England, October to December 2020.

BackgroundThe emergence of the SARS-CoV-2 Alpha variant in England coincided with a rapid increase in the number of PCR-confirmed COVID-19 cases in areas where the variant was concentrated.AimOur aim was to assess whether infection with Alpha was associated with more severe clinical outcomes than the wild type.MethodsLaboratory-confirmed infections with genomically sequenced SARS-CoV-2 Alpha and wild type between October and December 2020 were linked to routine healthcare and surveillance datasets.

Comparative analysis of the risks of hospitalisation and death associated with SARS-CoV-2 omicron (B.1.1.529) and delta (B.1.617.2) variants in England: a cohort study.

Long-Term Health-Related Quality of Life in Non-Hospitalized Coronavirus Disease 2019 (COVID-19) Cases With Confirmed Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Infection in England: Longitudinal Analysis and Cross-Sectional Comparison With Controls.

Background: We aimed to quantify the unknown losses in health-related quality of life of coronavirus disease 2019 (COVID-19) cases using quality-adjusted lifedays (QALDs) and the recommended EQ-5D instrument in England.

Methods: Prospective cohort study of nonhospitalized, polymerase chain reaction (PCR)-confirmed severe acute respiratory syndrome coronavirus 2-positive (SARS-CoV-2-positive) cases aged 12-85 years and followed up for 6 months from 1 December 2020, with cross-sectional comparison to SARS-CoV-2-negative controls. Main outcomes were QALD losses; physical symptoms; and COVID-19-related private expenditures.

Secondary attack rates in primary and secondary school bubbles following a confirmed case: Active, prospective national surveillance, November to December 2020, England.

Background: Following the full re-opening of schools in England and emergence of the SARS-CoV-2 Alpha variant, we investigated the risk of SARS-CoV-2 infection in students and staff who were contacts of a confirmed case in a school bubble (school groupings with limited interactions), along with their household members.

Methods: Primary and secondary school bubbles were recruited into sKIDsBUBBLE after being sent home to self-isolate following a confirmed case of COVID-19 in the bubble. Bubble participants and their household members were sent home-testing kits comprising nasal swabs for RT-PCR testing and whole genome sequencing, and oral fluid swabs for SARS-CoV-2 antibodies.

Patient satisfaction with HIV care service in Spain: results from a cross-sectional patient survey.

Understanding patient satisfaction with healthcare services can help identify patients' unmet needs and increase treatment adherence. This study aimed to evaluate the satisfaction of people living with HIV with overall HIV care service in Navarra, Spain, using a cross-sectional survey. The survey included a patient-reported experience measure (PREMs) consisting of five statements, and participants were also asked to rate the overall care they receive from the HIV service.

Brief report: HIV-related healthcare stigma/discrimination and unmet needs among persons living with HIV in England and Wales.

We characterized the prevalence of, and estimated associations between, (1) HIV-related healthcare stigma/discrimination and (2) unmet social, mental, and chronic condition healthcare needs among persons living with HIV (PLHIV) in England and Wales. We used data from Positive Voices 2017, a national, cross-sectional probability survey of PLHIV in England and Wales, in which  = 3,475 PLHIV provided complete data on demographic characteristics (control variables; age, ethnicity, gender, sexual identity), HIV-related healthcare stigma/discrimination (exposures; treated differently from other patients, care was refused/delayed, worried about being treated differently, avoided seeking needed care, all due to HIV status), and unmet needs (outcomes; unmet peer support, psychological care, management of chronic health conditions, and isolation help needs). Modified Poisson regression models with log links and robust variance estimators were used to produce prevalence ratios and 95% confidence intervals for unadjusted and adjusted associations between demographic characteristics, HIV-related healthcare stigma/discrimination (individual items and total scale score), and unmet needs variables.
