Global risk taking and decision making amongst live paired renal transplant patients

The proposed research project is designed to advance global scientific knowledge of decision making and risk taking amongst candidates for live paired renal transplants. The study will focus upon the transplant team, patient, donor and their social networks in the context of the decision making process, quality and decision readiness to proceed with live paired organs. More specifically, how the transplant team, recipients, donors and patient’s wider social networks communicate knowledge and the manner in which the experience of chronic illness (kidney failure) impacts upon the decision making process. We are particularly interested to study decision making and risk taking amongst minority groups (e.g. Black and Asian populations) who, according to the NHS Organ Donor Register, are three times as likely to need an organ transplant than their caucasian counterparts, but less likely to donate an organ. Also women, who are more likely to be organ donors and less likely to receive a donor organ, than their male counterparts

PROMISE: first-trimester progesterone therapy in women with a history of unexplained recurrent miscarriages - a randomised, double-blind, placebo-controlled, international multicentre trial and economic evaluation

BACKGROUND AND OBJECTIVES: Progesterone is essential to maintain a healthy pregnancy. Guidance from the Royal College of Obstetricians and Gynaecologists and a Cochrane review called for a definitive trial to test whether or not progesterone therapy in the first trimester could reduce the risk of miscarriage in women with a history of unexplained recurrent miscarriage (RM). The PROMISE trial was conducted to answer this question. A concurrent cost-effectiveness analysis was conducted. DESIGN AND SETTING: A randomised, double-blind, placebo-controlled, international multicentre study, with economic evaluation, conducted in hospital settings across the UK (36 sites) and in the Netherlands (nine sites). PARTICIPANTS AND INTERVENTIONS: Women with unexplained RM (three or more first-trimester losses), aged between 18 and 39 years at randomisation, conceiving naturally and giving informed consent, received either micronised progesterone (Utrogestan(®), Besins Healthcare) at a dose of 400 mg (two vaginal capsules of 200 mg) or placebo vaginal capsules twice daily, administered vaginally from soon after a positive urinary pregnancy test (and no later than 6 weeks of gestation) until 12 completed weeks of gestation (or earlier if the pregnancy ended before 12 weeks). MAIN OUTCOME MEASURES: Live birth beyond 24 completed weeks of gestation (primary outcome), clinical pregnancy at 6-8 weeks, ongoing pregnancy at 12 weeks, miscarriage, gestation at delivery, neonatal survival at 28 days of life, congenital abnormalities and resource use. METHODS: Participants were randomised after confirmation of pregnancy. Randomisation was performed online via a secure internet facility. Data were collected on four occasions of outcome assessment after randomisation, up to 28 days after birth. RESULTS: A total of 1568 participants were screened for eligibility. Of the 836 women randomised between 2010 and 2013, 404 received progesterone and 432 received placebo. The baseline data (age, body mass index, maternal ethnicity, smoking status and parity) of the participants were comparable in the two arms of the trial. The follow-up rate to primary outcome was 826 out of 836 (98.8%). The live birth rate in the progesterone group was 65.8% (262/398) and in the placebo group it was 63.3% (271/428), giving a relative risk of 1.04 (95% confidence interval 0.94 to 1.15; p = 0.45). There was no evidence of a significant difference between the groups for any of the secondary outcomes. Economic analysis suggested a favourable incremental cost-effectiveness ratio for decision-making but wide confidence intervals indicated a high level of uncertainty in the health benefits. Additional sensitivity analysis suggested the probability that progesterone would fall within the National Institute for Health and Care Excellence's threshold of £20,000-30,000 per quality-adjusted life-year as between 0.7145 and 0.7341. CONCLUSIONS: There is no evidence that first-trimester progesterone therapy improves outcomes in women with a history of unexplained RM. LIMITATIONS: This study did not explore the effect of treatment with other progesterone preparations or treatment during the luteal phase of the menstrual cycle. FUTURE WORK: Future research could explore the efficacy of progesterone supplementation administered during the luteal phase of the menstrual cycle in women attempting natural conception despite a history of RM.

Clinical Characteristics and Predictors of Outcomes of Hospitalized Patients With Coronavirus Disease 2019 in a Multiethnic London National Health Service Trust: A Retrospective Cohort Study.

BACKGROUND: Emerging evidence suggests ethnic minorities are disproportionately affected by coronavirus disease 2019 (COVID-19). Detailed clinical analyses of multicultural hospitalized patient cohorts remain largely undescribed. METHODS: We performed regression, survival, and cumulative competing risk analyses to evaluate factors associated with mortality in patients admitted for COVID-19 in 3 large London hospitals between 25 February and 5 April, censored as of 1 May 2020. RESULTS: Of 614 patients (median age, 69 [interquartile range, 25] years) and 62% male), 381 (62%) were discharged alive, 178 (29%) died, and 55 (9%) remained hospitalized at censoring. Severe hypoxemia (adjusted odds ratio [aOR], 4.25 [95% confidence interval {CI}, 2.36-7.64]), leukocytosis (aOR, 2.35 [95% CI, 1.35-4.11]), thrombocytopenia (aOR [1.01, 95% CI, 1.00-1.01], increase per 109 decrease), severe renal impairment (aOR, 5.14 [95% CI, 2.65-9.97]), and low albumin (aOR, 1.06 [95% CI, 1.02-1.09], increase per gram decrease) were associated with death. Forty percent (n = 244) were from black, Asian, and other minority ethnic (BAME) groups, 38% (n = 235) were white, and ethnicity was unknown for 22% (n = 135). BAME patients were younger and had fewer comorbidities. Although the unadjusted odds of death did not differ by ethnicity, when adjusting for age, sex, and comorbidities, black patients were at higher odds of death compared to whites (aOR, 1.69 [95% CI, 1.00-2.86]). This association was stronger when further adjusting for admission severity (aOR, 1.85 [95% CI, 1.06-3.24]). CONCLUSIONS: BAME patients were overrepresented in our cohort; when accounting for demographic and clinical profile of admission, black patients were at increased odds of death. Further research is needed into biologic drivers of differences in COVID-19 outcomes by ethnicity

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Nurses perspectives on their developing roles in hyper acute stroke setting and within the multidisciplinary team

Healthcare for London in collaboration with the Cardiac and Stroke Network and local NHS Trusts in London have introduced hyper acute stroke units (HASUs). HASU has been defined by Healthcare for London: • World-class stroke treatment 24-hours a day • Rapid assessment • Arrival on a specialist stroke ward within two hours of arrival to the emergency department (ED) • CT scan within 30 minutes of arrival to the ED • Thrombolysis if appropriate within 30 minutes of arrival to the ED • 24/7 monitoring in a high dependency bed • Multidisciplinary specialist stroke team, including consultants, nurses and therapists. Imperial College Healthcare NHS Trust opened a HASU on 1st February 2010. However, there is a lack of information on the nurses’ perspectives on their developing roles in the hyper acute stroke setting and within the multidisciplinary team. The aim of this study was to explore nurses’ perspectives on their developing roles within the hyper acute stroke setting and their role within the multidisciplinary team

Dataset for "Use of paediatric injectable medicines guidelines and associated medication administration errors: a human reliability analysis"

This dataset contains the raw discrepancy data from the post-hoc human reliability analysis performed for this paper. Video recordings of paediatric nurses preparing intravenous medicines during a resuscitation simulation (from a previous study) were re-analysed using human reliability analysis to identify discrepancies in the steps required to find and extract information from the NHS Injectable Medicines Guide (IMG) website. These data were combined with MAE data from the same original study. The dataset includes some medication error data from the previous study (dose and rate deviations, error severity score, clinically significant and large magnitude errors) and discrepancy data from this study (hierarchical task analysis node number, error mode, deviation contribution to an error, description of discrepancy)

The utility of a local multidisciplinary working group to oversee the establishment of rapidly evolving standards of care and to support trial recruitment during the COVID-19 pandemic

Coronavirus disease 2019 (COVID-19) was first identified in December 2019 in Wuhan, China. The first analyses of cases described high numbers of critically ill patients requiring intensive care admission with significant late inflammatory features. By the time the first cases of SARS-CoV-2 infection were diagnosed in the UK, a wide range of drugs were under consideration and it became clear that the input of clinicians covering all organ systems (in particular, infectious diseases, haematology, rheumatology, renal medicine and intensive care) and of expert specialist pharmacists was necessary at the local level. Thus, an expert multidisciplinary (MDT) group within our organisation was convened to offer a standardised approach and robust clinical governance for the treatment of COVID-19 patients admitted to our hospitals and rapidly develop standards of care as evidence evolved. This commentary explores the methods and mechanisms for creating an MDT COVID-19 treatment working group which are applicable to any hospital likely to admit and care for high numbers of COVID-19 patients and demonstrates how the structure and governance of the group allowed for rapid adoption of both dexamethasone and tocilizumab into standard of care as data became available
