RAND appropriateness panel to determine the applicability of UK guidelines on the management of acute respiratory distress syndrome (ARDS) and other strategies in the context of the COVID-19 pandemic.

BACKGROUND: COVID-19 has become the most common cause of acute respiratory distress syndrome (ARDS) worldwide. Features of the pathophysiology and clinical presentation partially distinguish it from 'classical' ARDS. A Research and Development (RAND) analysis gauged the opinion of an expert panel about the management of ARDS with and without COVID-19 as the precipitating cause, using recent UK guidelines as a template. METHODS: An 11-person panel comprising intensive care practitioners rated the appropriateness of ARDS management options at different times during hospital admission, in the presence or absence of, or varying severity of SARS-CoV-2 infection on a scale of 1-9 (where 1-3 is inappropriate, 4-6 is uncertain and 7-9 is appropriate). A summary of the anonymised results was discussed at an online meeting moderated by an expert in RAND methodology. The modified online survey comprising 76 questions, subdivided into investigations (16), non-invasive respiratory support (18), basic intensive care unit management of ARDS (20), management of refractory hypoxaemia (8), pharmacotherapy (7) and anticoagulation (7), was completed again. RESULTS: Disagreement between experts was significant only when addressing the appropriateness of diagnostic bronchoscopy in patients with confirmed or suspected COVID-19. Adherence to existing published guidelines for the management of ARDS for relevant evidence-based interventions was recommended. Responses of the experts to the final survey suggested that the supportive management of ARDS should be the same, regardless of a COVID-19 diagnosis. For patients with ARDS with COVID-19, the panel recommended routine treatment with corticosteroids and a lower threshold for full anticoagulation based on a high index of suspicion for venous thromboembolic disease. CONCLUSION: The expert panel found no reason to deviate from the evidence-based supportive strategies for managing ARDS outlined in recent guidelines.

SARS-CoV-2 and ECMO: early results and experience.

INTRODUCTION: In this paper, we describe our experience and early outcomes with critically unwell severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) patients who required extracorporeal membrane oxygenation (ECMO). We present our standard practices around ECMO decision-making, retrieval, cannulation, ventilation, anticoagulation, tracheostomy, imaging and steroids. METHODS: A retrospective cohort study using data from the hospital notes on all SARS-CoV-2 patients who required extracorporeal support at St Bartholomew's Hospital between 1 March 2020 and 31 July 2020. In total, this included 18 patients over this time period. RESULTS: In total, 18 patients were managed with extracorporeal support and of these 14 survived (78%) with 4 deaths (22%). The mean duration from hospital admission to intubation was 4.1 ± 3.4 days, mean time from intubation to ECMO 2.3 ± 2 days and mean run on ECMO 17.7 ± 9.4 days. Survivor mean days from intubation to extubation was 20.6 ± 9.9 days and survivor mean days from intubation to tracheostomy decannulation 46.6 ± 15.3 days. Time from hospital admission to discharge in survivors was a mean of 57.2 ± 25.8 days. Of the patients requiring extracorporeal support, the initial mode was veno-venous (VV) in 15 (83%), veno-arterial (VA) in 2 (11%) and veno-venous-arterial (VVA) in 1 (6%). On VV extracorporeal support, 2 (11%) required additional VVA. Renal replacement therapy was required in 10 (56%) of the patients. Anticoagulation target anti-Xa of 0.2-0.4 was set, with 10 (56%) patients having a deep vein thrombosis or pulmonary embolism detected and 2 (11%) patients suffering an intracranial haemorrhage. Tracheostomy was performed in 9 (50%) of the patients and high-dose methylprednisolone was given to 7 (39%) of the patients. CONCLUSION: In our cohort of patients with severe SARS-CoV-2 respiratory failure, a long period of invasive ventilation and extracorporeal support was required but achieving good outcomes despite this. There was a significant burden of thromboembolic disease and renal injury. A significant proportion of patients required tracheostomy and steroids to facilitate weaning.

Self-rated health and mortality in the UK: results from the first comparative analysis of the England and Wales, Scotland, and Northern Ireland Longitudinal Studies.

Previous studies have shown that self-reported health indicators are predictive of subsequent mortality, but that this association varies between populations and population sub-groups. For example, self-reported health is less predictive of mortality at older ages, has a stronger association with mortality for men than for women and is more predictive of mortality for those of lower than those of higher socio-economic status, particularly among middle aged working adults. This article explores this association using individual level, rather than ecological, data to see whether there are differences between the constituent countries of the UK in the relationship between self-reported health and subsequent mortality, and to investigate socio-economic inequalities in mortality more generally. Data are used from the three Census based longitudinal studies now available for England and Wales, Scotland and Northern Ireland.List of tables, 13.

Households and families: implications of changing census definitions for analyses using the ONS Longitudinal Study.

Longitudinal perspectives on caregiving, employment history and marital status in midlife in England and Wales.

In this paper, we examine associations between employment history and marital status and unpaid care provision among those aged 40-59 in England and Wales. We used data from a large nationally representative longitudinal study, the Office for National Statistics Longitudinal Study. Initially based on a sample drawn from the 1971 Census, in 2001 this study included data on 110,464 people aged 40-59 of whom 5% provided 20 or more hours per week of unpaid care. We analysed associations between caregiving of this intensity and current employment, employment history, employment characteristics, marital status, and employment after childbearing. Among men, caregiving was associated with a history of lower levels of employment. The small group of men with a history of least employment were 70% more likely to provide care than those with a history of most employment. Among women, caregiving was associated with a history of non-employment, but there were no differences between those with fully engaged and partially engaged labour market histories. Analyses of a subset of data on women who had a child between 1981 and 1991 showed that those who had returned to full-time paid work by 1991 were over 50% less likely to later become caregivers. Some associations between employment characteristics and propensity to provide 20 or more hours per week of care were also identified. Those in public sector jobs and those previously in employment with a caregiving dimension were 20-30% more likely than other working women to provide unpaid care. These results suggest a continuing gender dimension in care provision which interacts with marital status and employment in gender-specific ways. It also suggests that implementation of strategies to enable those in midlife to combine caregiving and work responsibilities, should they wish to do so, should be an urgent priority.

The association of cancer survival with four socioeconomic indicators: a longitudinal study of the older population of England and Wales 1981-2000.

BACKGROUND: Many studies have found socioeconomic differentials in cancer survival. Previous studies have generally demonstrated poorer cancer survival with decreasing socioeconomic status but mostly used only ecological measures of status and analytical methods estimating simple survival. This study investigate socio-economic differentials in cancer survival using four indicators of socioeconomic status; three individual and one ecological. It uses a relative survival method which gives a measure of excess mortality due to cancer. METHODS: This study uses prospective record linkage data from The Office for National Statistics Longitudinal Study for England and Wales. The participants are Longitudinal Study members, recorded at census in 1971 and 1981 and with a primary malignant cancer diagnosed at age 45 or above, between 1981 and 1997, with follow-up until end 2000. The outcome measure is relative survival/excess mortality, compared with age and sex adjusted survival of the general population. Relative survival and Poisson regression analyses are presented, giving models of relative excess mortality, adjusted for covariates. RESULTS: Different socioeconomic indicators detect survival differentials of varying magnitude and definition. For all cancers combined, the four indicators show similar effects. For individual cancers there are differences between indicators. Where there is an association, all indicators show poorer survival with lower socioeconomic status. CONCLUSION: Cancer survival differs markedly by socio-economic status. The commonly used ecological measure, the Carstairs Index, is adequate at demonstrating socioeconomic differentials in survival for combined cancers and some individual cancers. A combination of car access and housing tenure is more sensitive than the ecological Carstairs measure at detecting socioeconomic effects on survival--confirming Carstairs effects where they occur but additionally identifying effects for other cancers. Social class is a relatively weak indicator of survival differentials.

Who cares? Geographic variation in unpaid caregiving in England and Wales: evidence from the 2001 census.

This article investigates the prevalence of unpaid caregiving by local authority district in England and Wales, using data from a new question on caregiving in the 2001 Census. We also examine geographic variation in the characteristics of unpaid care providers including health status, socio-economic status and ethnicity. Results show clear geographic variations in caregiving. The proportion of adults providing more than 20 hours of care per week ranged from less than 2 per cent to nearly 8 per cent. The highest proportions of caregivers were found in areas with higher than average levels of deprivation and long-term illness. Carers in such areas were themselves more likely to be in poor health. There are also clear variations in caregiving propensity by ethnic group.
