ObjectivesIndividuals who receive a negative lateral flow coronavirus test result may misunderstand it as meaning ‘no risk of infectiousness’, giving false reassurance. This experiment tested the impact of adding information to negative test result messages about residual risk and the need to continue protective behaviours.Design.4 (residual risk) × 2 (post-test result behaviours) between-subjects design.Setting.Online.Participants1200 adults from a representative UK sample recruited via Prolific (12–15 March 2021).InterventionsParticipants were randomly allocated to one of eight messages. Residual risk messages were: (1) ‘Your coronavirus test result is negative’ (control); (2) message 1 plus ‘It’s likely you were not infectious when the test was done’ (current NHS Test & Trace (T&T); (3) message 2 plus ‘But there is still a chance you may be infectious’ (elaborated NHS T&T); and (4) message 3 plus infographic depicting residual risk (elaborated NHS T&T+infographic). Each message contained either no additional information or information about the need to continue following guidelines and protective behaviours.Outcome measures(1) Proportion understanding residual risk of infectiousness and (2) likelihood of engaging in protective behaviours (scales 1–7).ResultsThe control message decreased understanding relative to the current NHS T&T message: 54% versus 71% (Adjusted Odds Ratio (AOR)=0.56 95% CI 0.34 to 0.95, p=0.030). Understanding increased with the elaborated NHS T&T (89%; AOR=3.25 95% CI 1.64 to 6.42, p=0.001) and elaborated NHS T&T+infographic (91%; AOR=5.16 95% CI 2.47 to 10.82, p<0.001) compared with current NHS T&T message. Likelihood of engaging in protective behaviours was unaffected by information (AOR=1.11 95% CI 0.69 to 1.80, χ2(1)=0.18, p=0.669), being high (M=6.4, SD=0.9) across the sample.ConclusionsA considerable proportion of participants misunderstood the residual risk following a negative test result. The addition of a single sentence (‘But there is still a chance you may be infectious’) to current NHS T&T wording increased understanding of residual risk.Trial registration numberOSF: https://osf.io/byfz3/

ObjectivesTo assess multiple preventive care measures and to examine their associations with having a usual source of primary care and primary care performance during the COVID-19 pandemic in Japan.DesignNationwide cross-sectional study.SettingJapanese general adult population.Participants1757 adult residents.Primary outcome measuresFourteen preventive care measures aggregated the overall screening, immunisation and counselling composites.ResultsDepression screening, zoster vaccination and tetanus vaccination had low implementation rates even among participants with a usual source of primary care. After adjustment for possible confounders, having a usual source of primary care was positively associated with all preventive care composites. Primary care performance assessed by the Japanese version of Primary Care Assessment Tool Short Form was also dose dependently associated with an increase in all composites. Results of the sensitivity analyses using a different calculation of preventive care composite were similar to those of the primary analyses.ConclusionsReceipt of primary care, particularly high-quality primary care, contributed to increased preventive care utilisation even during the COVID-19 pandemic. However, the rate of mental health screening in primary care was at a very low level. Therefore, addressing mental health issues should be a major challenge for primary care providers during and after the pandemic.

PurposeRetinal signatures of systemic disease (‘oculomics’) are increasingly being revealed through a combination of high-resolution ophthalmic imaging and sophisticated modelling strategies. Progress is currently limited not mainly by technical issues, but by the lack of large labelled datasets, a sine qua non for deep learning. Such data are derived from prospective epidemiological studies, in which retinal imaging is typically unimodal, cross-sectional, of modest number and relates to cohorts, which are not enriched with subpopulations of interest, such as those with systemic disease. We thus linked longitudinal multimodal retinal imaging from routinely collected National Health Service (NHS) data with systemic disease data from hospital admissions using a privacy-by-design third-party linkage approach.ParticipantsBetween 1 January 2008 and 1 April 2018, 353 157 participants aged 40 years or older, who attended Moorfields Eye Hospital NHS Foundation Trust, a tertiary ophthalmic institution incorporating a principal central site, four district hubs and five satellite clinics in and around London, UK serving a catchment population of approximately six million people.Findings to dateAmong the 353 157 individuals, 186 651 had a total of 1 337 711 Hospital Episode Statistics admitted patient care episodes. Systemic diagnoses recorded at these episodes include 12 022 patients with myocardial infarction, 11 735 with all-cause stroke and 13 363 with all-cause dementia. A total of 6 261 931 retinal images of seven different modalities and across three manufacturers were acquired from 1 54 830 patients. The majority of retinal images were retinal photographs (n=1 874 175) followed by optical coherence tomography (n=1 567 358).Future plansAlzEye combines the world’s largest single institution retinal imaging database with nationally collected systemic data to create an exceptional large-scale, enriched cohort that reflects the diversity of the population served. First analyses will address cardiovascular diseases and dementia, with a view to identifying hidden retinal signatures that may lead to earlier detection and risk management of these life-threatening conditions.

ObjectivesPerceived capacity denotes a subjective sense of having resources to cope with strains and hardships, and hence maternal perceived capacity may be protective against risk factors for child maltreatment. This study investigated the longitudinal association between maternal perceived capacity in life and child maltreatment.DesignThis population-based longitudinal study used self-reported questionnaires from the Tokyo Teen Cohort study (TTC), a large community-based cohort study conducted in Japan between 2014 and 2019.SettingMother–child pairs were randomly recruited from the resident registries of three municipalities in Tokyo, Japan.MethodsA total of 2515 mothers participated. Mothers’ perceived capacity in life was evaluated using the self-reported TTC wave 2 survey when their children were 12 years old. Mothers rated the extent to which they had capacity in terms of time, finance, physical well-being, mental well-being and life in general. Physical punishment, which is linked to more severe childhood maltreatment, was assessed using a question about the use of physical punishment at the wave 3 survey when children were 14 years old.ResultsAfter controlling for baseline covariates (including maternal social support, age, marital status, annual household income, educational attainment, child’s age, gender, sibling and birth order, and behavioural difficulties), higher perceived capacity in finance (OR 0.95, 95% CI 0.90 to 0.99, p=0.026) and mental well-being (OR 0.93, 95% CI 0.88 to 0.98, p=0.005) were associated with less frequent use of physical punishment with 14-year-old children.ConclusionsMaternal perceived capacity in finance and mental well-being may decrease the risk of frequent use of physical punishment at the 2-year follow-up. Child maltreatment prevention strategies should aim to empower mothers and promote their perceived capacity in financial management and mental health.

IntroductionPhysical and mental health are often affected in chronic obstructive pulmonary disease (COPD) adversely affecting disease course and quality of life. Abnormalities in whole body and cellular energy metabolism, dietary and plasma nutrient status and intestinal permeability have been well established in these patients as systemic determinants of functional decline and underexplored treatable traits. The aim of this study is to investigate the efficacy of 1 year targeted nutrient supplementation on physical activity level and health-related quality of life in patients with COPD.Methods and analysisThis study is a single-centre randomised, placebo-controlled, double-blind trial in 166 patients with COPD recruited from multiple hospitals in the Netherlands. The intervention group will receive a multinutrient supplement, including vitamin D, tryptophan, long-chain polyunsaturated fatty acids and prebiotic dietary fibres as main components (94 kCal per daily dose). The control group will receive an isocaloric isonitrogenous placebo. Both groups will ingest one portion per day for at least 12 months and will additionally receive counselling on healthy lifestyle and medical adherence over the course of the study. Coprimary outcomes are physical activity assessed by triaxial accelerometry and health-related quality of life measured by the EuroQol-5 dimensions questionnaire. Secondary outcomes are cognitive function, psychological well-being, physical performance, patient-reported outcomes and the metabolic profile assessed by body composition, systemic inflammation, plasma nutrient levels, intestinal integrity and microbiome composition. Outcomes will be measured at baseline and after 12 months of supplementation. In case patients are hospitalised for a COPD exacerbation, a subset outcome panel will be measured during a 4-week recovery period after hospitalisation.Ethics and disseminationThis study was approved by the local Ethics Committee of Maastricht University. Subjects will be included after written informed consent is provided. Study outcomes will be disseminated through presentations at (inter)national conferences and through peer-reviewed journals.Trial registrationNCT03807310.

Published: March 2022

IntroductionPrescribing and medication use in palliative care is a multistep process. It requires systems coordination and is enacted through activities of patients, informal carers and professionals. This study compares practice to idealised descriptions of what should happen; identifying when, how and why process disturbances impact on quality and safety. Our objectives are to:Document an intended model (phase 1, scoping review).Refine the model with study of practice (phase 2, ethnography).Use the model to pinpoint ‘hot’ (viewed as problematic by participants) and ‘cold’ spots (observed as problematic by researchers) within or when patients move across three contexts-hospice, hospital and community (home).Create learning recommendations for quality and safety targeted at underlying themes and contributing factors.Methods and analysisThe review will scope Ovid Medline, CINAHL and Embase, Google Scholar and Images—no date limits, English language only. The Population (palliative), Concept (medication use), Context (home, hospice, hospital) framework defines inclusion/exclusion criteria. Data will be extracted to create a model illustrating how processes ideally occur, incorporating multiple steps of typical episodes of prescribing and medication use for symptom control. Direct observations, informal conversations around acts of prescribing and medication use, and semistructured interviews will be conducted with a purposive sample of patients, carers and professionals. Drawing on activity theory, we will synthesise analysis of both phases. The analysis will identify when, how and why activities affect patient safety and experience. Generating a rich multivoiced understanding of the process will help identify meaningful targets for improvement.Ethics and disseminationEthical approval granted by the Camden & Kings Cross NHS Regional Ethics Committee (21/LO/0459). A patient and public involvement (PPI) coinvestigator, a multiprofessional steering group and a PPI engagement group are working with the research team. Dissemination of findings is planned through peer-reviewed publications and a stakeholder (policymakers, commissioners, clinicians, researchers, public) report/dissemination event.

Published: March 2022

IntroductionDespite increasing prevalence, European family homelessness remains under-researched.MethodsA retrospective review was performed of homeless children attending a paediatric emergency department in Dublin, Ireland, from 1 January 2017 to 31 December 2020. Comparison was made with a random cohort of 1500 non-homeless paediatric attendances in 2019. Homelessness was defined using the European Typology of Homelessness and Housing Exclusion, including those with addresses of no fixed abode, government homeless accommodation and certain residential settings. The objectives were to compare presentations between homeless and non-homeless children. We were interested in determining differences regarding demographics, healthcare utilisation, clinical presentation and outcomes.ResultsOf 197 437 attendances 3138 (1.59%) were homeless. Compared with the non homeless, homeless children were less likely to be ethnically Irish (37.4% vs 74.6%, p<0.001) or have been born in Ireland (82.3% vs 96.2%, p<0.001). Irish Travellers (3% vs 0.8%), Roma (22.5% vs 2.4%) and black (21.1% vs 4.2%) ethnicities were over-represented (p<0.001) in the homeless cohort.Homeless children were younger (age <12 months: 26% vs 16%; p<0.001), less likely to be fully vaccinated (73.6% vs 81.9%, p<0.001) and have registered general practitioners (89.7% vs 95.8%, p<0.001). They were more likely to represent within 2 weeks (15.9% vs 10.5%, p<0.001), and use ambulance transportation (13.2% vs 6.7%, p<0.001). Homeless children had lower acuity presentations (triage category 4–5: 47.2% vs 40.7%, p<0.001) and fewer admissions (5.9% vs 8.4%, p<0.001) than non-homeless children.DiscussionInfants, Irish Travellers, Roma and black ethnicities were over-represented in homeless presentations. Homeless children had increased reliance on emergency services for primary healthcare needs.

ObjectiveTo describe the diagnosis and treatment of patent ductus arteriosus (PDA) in infants born at <32 weeks’ gestational age (GA) in England and Wales between 2010 and 2017.Study designRetrospective cohort study using routinely recorded data from the National Neonatal Research Database of infants born at <32 weeks admitted to neonatal units in England and Wales from 2010 to 2017.ResultsAmong 58 108 infants born at <32 weeks’ GA, 28.3% (n=16 440) had a PDA diagnosed clinically or with echocardiographic confirmation. Of these, 34.8% (n=5721; 9.8% of total <32 weeks’ infants included) had PDA treatment including 7.6% (n=1255) with indomethacin, 23.5% (n=3857) with ibuprofen and 5.6% (n=916) with surgical closure. The highest incidence of PDA was among infants born at 24 and 25 weeks’ GA (70.2% and 70.8%, respectively), decreasing to 6.1% among infants born at 31 weeks’ GA. The percentage of infants with a PDA increased over the study period (25.5% in 2010 to 28.5% in 2017). The percentage of infants who received ibuprofen or indomethacin or had PDA surgery decreased from 41.3% in 2010 to 33.7% in 2017, with an increase in use of ibuprofen from 20.2% to 27.3% while use of indomethacin decreased from 20.0% to 8.8%. Surgical closure of PDA decreased from 9.1% to 3.0%. Indomethacin was used for median (IQR) 3 (2–5) days while ibuprofen was given for 3 (2-4) days, at a median of 8 and 10 days after birth, respectively; surgical treatment was used later at 33 (24–45) days after birth.ConclusionsIbuprofen is the preferred drug and surgical interventions are becoming less frequent for PDA closure among very preterm infants in England and Wales.Trial registration numberNCT03773289.

BackgroundEndovascular thrombectomy (EVT) for ischemic stroke (IS) beyond 6 hours has been proven effective in randomized controlled trials. We present data on implementation and outcomes for EVT beyond 6 hours in Sweden.MethodsWe included all cases of anterior circulation IS caused by occlusion of the intracranial carotid artery, and the M1 or M2 segment of the middle cerebral artery, registered in two nationwide quality registers for stroke in 2015–2020. Three groups were defined from onset-to-groin-puncture (OTG) time: early window (<6 hours), late window (6–24 hours) known onset, late window last seen well (LSW). Favorable outcome (modified Rankin Scale (mRS) 0–2) and all-cause mortality at 90 days were the main outcomes, and symptomatic intracerebral hemorrhage (sICH) was the safety outcome.ResultsLate window EVT increased from 0.3% of all IS in 2015 to 1.8% in 2020, and from 17.4% of all anterior circulation EVTs in 2015 to 32.9% in 2020. Of 2199 patients, 76.9% (n=1690) were early window EVTs and 23.1% late window EVTs (n=509; 141 known onset, 368 LSW). Median age was 73 years, and 46.2% were female, with no differences between groups. Favorable outcome did not differ between groups (early window 42.4%, late window known onset 38.9%, late window LSW 37.3% (p=0.737)) and remained similar when adjusted for baseline differences. sICH rates did not differ (early window 4.0%, late window known onset 2.1%, late window LSW 4.9% (p=0.413)).ConclusionLate window EVTs have increased substantially over time, and currently account for one third of anterior circulation treatments. Early and late window patients had similar outcomes.

BackgroundThe effects of aortic occlusion (AO) on brain injury are not well defined. We examined the impact of AO by resuscitative endovascular balloon occlusion of the aorta (REBOA) and resuscitative thoracotomy (RT) on outcomes in the setting of traumatic brain injury (TBI).MethodsPatients sustaining TBI who underwent RT or REBOA in zone 1 (thoracic aorta) from September 2013 to December 2018 were identified. The indication for REBOA or RT was hemodynamic collapse due to hemorrhage below the diaphragm. Primary outcomes included mortality and systemic complications.Results282 patients underwent REBOA or RT. Of these, 76 had mild TBI (40 REBOA, 36 RT) and 206 sustained severe TBI (107 REBOA, 99 RT). Overall, the mean (±SD) age was 42±17 years, with an Injury Severity Score (ISS) of 40±17 and mean systolic blood pressure (SBP) at the time of REBOA or RT of 81±34 mm Hg. REBOA patients had a mean SBP at the time of AO of 78.39±29.45 mm Hg, whereas RT patients had a mean SBP of 83.18±37.87 mm Hg at the time of AO (p=0.24). 55% had ongoing cardiopulmonary resuscitation (CPR) at the time of AO, and the in-hospital mortality was 86%. Binomial logistic regression controlling for TBI severity, age, ISS, SBP at the time of AO, crystalloid infusion, and CPR during AO demonstrated that the odds of mortality are 3.1 times higher for RT compared with REBOA. No significant differences were found in systemic complications between RT and REBOA.DiscussionPatients with TBI who receive REBOA may have improved survival, but no difference in systemic complications, compared with patients who receive RT for the same indication. Although some patients are receiving RT prior to arrest for extrathoracic hemorrhagic shock, these results suggest that REBOA should be considered as an alternative to RT when RT is chosen for the sole purpose of resuscitation in the setting of TBI.Level of evidence4.
