Newest firstNorovirus is one of the most common gastrointestinal pathogens and causes substantial morbidity and mortality worldwide. A serious consequence can be acute kidney injury (AKI), characterised by a rapid deterioration of kidney function, which is associated with prolonged hospital admissions and increased mortality. This study aimed to quantify the contribution of norovirus community transmission to AKI hospitalisat…
Open article record in new tab ↗ObjectivesWe aimed to estimate how rheumatology healthcare use has changed since the COVID-19 pandemic and determine demographic characteristics associated with observed changes in healthcare use. MethodsUsing three primary and secondary care electronic health record datasets in England (with the approval of NHS England), Scotland, and Wales, we identified individuals with a diagnosis of rheumatoid arthritis (RA)…
Open article record in new tab ↗ObjectivesTo examine the impact of the pandemic on deprivation-related inequalities in hospitalisations for CVD conditions in Denmark and England between March 2018 and December 2021. DesignA series of monthly cross-sectional studies separately in England and Denmark. Setting: With the approval of NHS England, we used English primary care electronic health records, linked to secondary care and death registry data…
Open article record in new tab ↗BackgroundAcute Kidney Injury (AKI) is a multifactorial condition which presents a substantial burden to healthcare systems. There is limited evidence on whether it is seasonal. We sought to investigate the seasonality of AKI hospitalisations in England and use unsupervised machine learning to explore clustering of underlying comorbidities, to gain insights for future intervention. MethodsWe used Hospital Episodes…
Open article record in new tab ↗BackgroundThe COVID-19 pandemic disrupted healthcare and may have impacted ethnic inequalities in healthcare. We aimed to describe the impact of pandemic-related disruption on ethnic differences in clinical monitoring and hospital admissions for non-COVID conditions in England. MethodsWe conducted a cohort study using OpenSAFELY (2018-2022). We grouped ethnicity (exposure), into five categories: White, South Asian…
Open article record in new tab ↗BackgroundCardiovascular disease (CVD) is a leading cause of death globally. Angiotensin-converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB), compared in the ONTARGET trial, each prevent CVD. However, trial populations may not be representative of the general population. MethodsUsing trial replication methods within routine-care data, we explored replicability of the ONTARGET trial. For peo…
Open article record in new tab ↗ObjectivesTo compare the effectiveness of the BNT162b2 mRNA (Pfizer-BioNTech) and the ChAdOx1 (Oxford-AstraZeneca) COVID-19 vaccines against infection and COVID-19 disease in health and social care workers. DesignCohort study, emulating a comparative effectiveness trial. SettingLinked primary care, hospital, and COVID-19 surveillance records available within the OpenSAFELY-TPP research platform. Participants317,34…
Open article record in new tab ↗BackgroundThere is concern about medium to long-term adverse outcomes following acute COVID-19, but little relevant evidence exists. We aimed to investigate whether risks of hospital admission and death, overall and by specific cause, are raised following discharge from a COVID-19 hospitalisation. Methods and FindingsWorking on behalf of NHS-England, we used linked primary care and hospital data in OpenSAFELY to c…
Open article record in new tab ↗BackgroundThe impact of long COVID is considerable, but risk factors are poorly characterised. We analysed symptom duration and risk factor from 10 longitudinal study (LS) samples and electronic healthcare records (EHR). MethodsSamples: 6907 adults self-reporting COVID-19 infection from 48,901 participants in the UK LS, and 3,327 adults with COVID-19, were assigned a long COVID code from 1,199,812 individuals in p…
Open article record in new tab ↗BackgroundThe COVID-19 pandemic has disrupted healthcare activity globally. The NHS in England stopped most non-urgent work by March 2020, but later recommended that services should be restored to near-normal levels before winter where possible. The authors are developing the OpenSAFELY NHS Service Restoration Observatory, using data to describe changes in service activity during COVID-19, and reviewing signals fo…
Open article record in new tab ↗ImportanceDeaths among patients with coronavirus disease 2019 (COVID-19) are partially attributed to venous thromboembolism and arterial thromboses. Anticoagulants prevent thrombosis formation, possess anti-inflammatory and anti-viral properties, and may be particularly effective for treating patients with COVID-19. ObjectiveTo evaluate whether initiation of prophylactic anticoagulation within 24 hours of admissio…
