Summary Identification of high‐risk patients admitted to intensive care with COVID‐19 may inform management strategies. The objective of this meta‐analysis was to determine factors associated with mortality among adults with COVID‐19 admitted to intensive care by searching databases for studies published between 1 January 2020 and 6 December 2020. Observational studies of COVID‐19 adults admitted to critical care were included. Studies of mixed cohorts and intensive care cohorts restricted to a specific patient sub‐group were excluded. Dichotomous variables were reported with pooled OR and 95%CI, and continuous variables with pooled standardised mean difference (SMD) and 95%CI. Fifty‐eight studies (44,305 patients) were included in the review. Increasing age (SMD 0.65, 95%CI 0.53–0.77); smoking (OR 1.40, 95%CI 1.03–1.90); hypertension (OR 1.54, 95%CI 1.29–1.85); diabetes (OR 1.41, 95%CI 1.22–1.63); cardiovascular disease (OR 1.91, 95%CI 1.52–2.38); respiratory disease (OR 1.75, 95%CI 1.33–2.31); renal disease (OR 2.39, 95%CI 1.68–3.40); and malignancy (OR 1.81, 95%CI 1.30–2.52) were associated with mortality. A higher sequential organ failure assessment score (SMD 0.86, 95%CI 0.63–1.10) and acute physiology and chronic health evaluation‐2 score (SMD 0.89, 95%CI 0.65–1.13); a lower PaO2:FIO2 (SMD −0.44, 95%CI −0.62 to −0.26) and the need for mechanical ventilation at admission (OR 2.53, 95%CI 1.90–3.37) were associated with mortality. Higher white cell counts (SMD 0.37, 95%CI 0.22–0.51); neutrophils (SMD 0.42, 95%CI 0.19–0.64); D‐dimers (SMD 0.56, 95%CI 0.43–0.69); ferritin (SMD 0.32, 95%CI 0.19–0.45); lower platelet (SMD −0.22, 95%CI −0.35 to −0.10); and lymphocyte counts (SMD −0.37, 95%CI −0.54 to −0.19) were all associated with mortality. In conclusion, increasing age, pre‐existing comorbidities, severity of illness based on validated scoring systems, and the host response to the disease were associated with mortality; while male sex and increasing BMI were not. These factors have prognostic relevance for patients admitted to intensive care with COVID‐19.

All pregnant women in the United Kingdom are offered and encouraged to take up screening for human immunodeficiency virus (HIV), hepatitis B and syphilis, with excellent uptake rates and engagement in care resulting in very few infants being infected with HIV in the United Kingdom. However, in that small number of women who decline testing, there remains an opportunity to offer further support to test and engage them and their baby in care, even if this happens in labour or immediately after birth. In addition, these women may be at increased risk of HIV. Our hospital is in an extremely high prevalence area for HIV, and most untested individuals are of childbearing age. We embarked on a quality improvement project to engage all women delivering at our unit in HIV testing or to test their babies via cord blood at birth. We sought to do this in a constructive and inclusive way, led by the HIV specialist midwife with the support of the HIV antenatal and the hospital senior management teams. Following an initial evaluation, the approach was modified and an innovative approach together with a trusted advocate was used to engage a particularly hard-to-reach group. We have achieved 100% uptake of HIV testing and made two HIV diagnoses that would not otherwise have been made; both in women who reported themselves not to be at risk and both engaged in care and delivered HIV-negative infants.

transmission paths of microbes and an understanding of human interaction with surfaces. This additional research will provide valuable insight into ideal surface characteristics, optimum timing for hand hygiene, and support the development of evidence based effective cleaning and disinfection protocols and processes to interrupt the spread of pathogens.
