Background: The non‐operative management of splenic injury in children is recommended widely, and is possible in over 95 per cent of episodes. Practice appears to vary between centres. Methods: The Trauma Audit and Research Network (TARN) database was interrogated to determine the management of isolated paediatric splenic injuries in hospitals in England and Wales. Rates of non‐operative management, duration of hospital stay, readmission and mortality were recorded. Management in paediatric surgical hospitals was compared with that in adult hospitals. Results: Between January 2000 and December 2015 there were 574 episodes. Children treated in a paediatric surgical hospital had a 95·7 per cent rate of non‐operative management, compared with 75·5 per cent in an adult hospital (P < 0·001). Splenectomy was done in 2·3 per cent of children in hospitals with a paediatric surgeon and in 17·2 per cent of those treated in an adult hospital (P < 0·001). There was a significant difference in the rate of non‐operative management in children of all ages. There was some improvement in non‐operative management in adult hospitals in the later part of the study, but significant ongoing differences remained. Conclusion: The management of children with isolated splenic injury is different depending on where they are treated. The rate of non‐operative management is lower in hospitals without a paediatric surgeon present. Better in hospitals with a paediatric surgeon [ABSTRACT FROM AUTHOR]

Background: There is a paucity of UK data to aid healthcare professionals in predicting which patients hospitalised with community-acquired pneumonia (CAP) are at greatest risk of 30-day readmission and to determine which readmissions may occur soonest., Methods: An analysis of CAP cases admitted to nine UK hospitals participating in the Advancing Quality Pneumonia Programme., Results: An analysis was performed of 12 157 subjects hospitalised with CAP in the Advancing Quality Programme Database. 26% of those discharged were readmitted within 30 days with readmission predicted by comorbidity including non-metastatic cancer, diabetes with complications and chronic kidney disease. 41% and 66% of readmissions occurred within 7 and 14 days of discharge, respectively. Patients readmitted within 14 days were more likely to have metastatic cancer (6.6% vs 4.5%; p=0.03) compared with those readmitted at 15-30 days., Conclusions: A quarter of patients hospitalised for CAP are readmitted within 30 days; of those, two-thirds are readmitted within 2 weeks. Further research is required to determine whether such readmissions might be preventable through imple menting measures including in-hospital cross-specialty comorbidity management, convalescence in intermediate care, targeted rehabilitation and advanced care planning., Competing Interests: Competing interests: The National Health Service employer of BC was reimbursed for the time spent performing clinical advisor roles for the Advancing Quality Pneumonia Programme., (© Author(s) (or their employer(s)) 2021.

Objective: To develop a community-informed definition of child and youth thriving and identify community priorities for child/youth thriving., Methods: Through concept mapping, a mixed-methods community-based participatory research method, this study examined community and health professionals' conceptualizations of child and youth thriving. We conducted brainstorming, sorting and rating, and interpretation sessions in 3 geographically distinct neighborhoods with concentrated disadvantage; simultaneously, researchers and health professionals participated in online sessions., Results: Participants included 91 community members, health care and social service professionals, and researchers who identified 104 items related to child and youth thriving and grouped these items into 7 distinct clusters. Two clusters focused on child-level factors (Strong Minds and Bodies; Positive Identity and Self-Worth), 2 focused on place-based factors (Healthy Environments; Vibrant Communities), and 3 focused on relationships and interactions between children and their environments (Caring Families and Relationships; Safety; and Fun and Happiness). The community-informed conceptualization of child thriving builds on previous models, adding dimensions of physical health and safety. Participants ranked having "someone to talk to," being "comfortable in their own skin," having "pride in themselves," and having a "strong sense of self and self-worth" as most important to child and youth thriving., Conclusions: By integrating perspectives of community members from diverse neighborhoods with those of researchers and health professionals, this study captures novel domains to inform a conceptual model of thriving that focuses on stakeholder priorities. Findings will guide development, implementation, and evaluation of community-based interventions and their impact on child and adolescent health and thriving., (Copyright © 2020 Academic Pediatric Association.

Introduction: Lower-limb prosthesis users (LLPUs) experience increased fall risk due to gait and balance impairments. Clinical outcome measures are useful for measuring balance impairment and fall risk screening but suffer from limited resolution and ceiling effects. Recent advances in wearable sensors that can measure different components of gait stability may address these limitations. This study assessed feasibility and construct validity of a wearable sensor system (APDM Mobility Lab) to measure postural control and gait stability., Materials and Methods: Lower-limb prosthesis users (n=22) and able-bodied controls (n=24) completed an Instrumented Stand-and-Walk Test (ISAW) while wearing the wearable sensors. Known-groups analysis (prosthesis versus controls) and convergence analysis (Prosthetic Limb Users Survey of Mobility [PLUS-M] and Activity-specific Balance Confidence [ABC] Scale) were performed on 20 stability-related measures., Results: The system was applied without complications; however missing anticipatory postural adjustment data points for nine subjects affected the analysis. Of the 20 analyzed measures output by the sensors, only three significantly differed (p≤.05) between cohorts, and two demonstrated statistically significant correlations with the self-report measures., Conclusions: The results of this study suggest the clinical feasibility but only partial construct validity of the wearable sensor system in conjunction with the ISAW test to measure LLPU stability and balance. The sample consisted of high-functioning LLPUs, so further research should evaluate a more representative sample with additional outcome measures and tasks., Competing Interests: Declaration of conflicting interests The authors declare no conflicts of interest.

Background: Historically, reported survival from traumatic cardiac arrest (TCA) was extremely low. More recent publications have recorded survival to discharge of up to 8%. This improvement is likely to be multi-factorial; however, there are currently no published data describing the epidemiology or aetiology of TCA in England and Wales to guide future practice improvement., Methods: Population-based analysis of 2009-2015 Trauma Audit and Research Network (TARN) data. The primary aim was to describe the 30-day survival following TCA. Patients of all ages with traumatic cardiac arrest pre-hospital or in the emergency department (ED) were included. Data are described as number (%), and median [interquartile range]. Two-group analysis with Chi-squared test was performed., Results: During the study period 227,944 patients were included in the TARN database. Seven hundred and five (0.3%) suffered TCA: 74.3% were male, aged 44.3 [25.2-83.2] years, ISS 29 [21-75], and 601 (85.2%) had blunt injuries. 612 (86.8%) had a severe traumatic brain injury and or severe haemorrhage. Overall 30-day survival was 7.5% (95%CI 5.6-9.5) - 'pre-hospital only' TCA 11.5%, 'ED only' TCA 3.9%, p<0.02. No patients who were in TCA both pre-hospital and in the ED survived., Conclusion: This study has shown that short-term survival from TCA in this large civilian registry is 7.5%. Early and aggressive management of patients with TCA, using protocols that target the reversible causes of TCA, should be initiated. Further work to establish novel ways to manage patients with reversible causes of TCA is indicated. Resuscitation in this patient group is not futile., (Crown Copyright © 2016.

Objective: To define the relationship between preinjury warfarin use and mortality in a large European sample of trauma patients., Methods: A multicentred study was conducted using data collated from European (predominately English and Welsh) trauma receiving hospitals. Patient data from the Trauma Audit and Research Network database from 2009 to 2013 were analysed. Univariate and multivariate logistic regression was used to estimate OR for mortality associated with preinjury warfarin use in the whole adult trauma cohort and a matched sample of patients comparable in terms of age, gender, GCS, pre-existing medical conditions and injury severity., Results: A total of 136 617 adult trauma patients (2009-2013) were included, with 499 patients reported to be using warfarin therapy at the time of trauma. Preinjury warfarin use was associated with a significantly higher mortality rate at 30 days postinjury compared with the non-users. Following adjustment of age, injury severity and GCS, preinjury warfarin use was associated with increased mortality in trauma patients (adjusted OR 2.14; 95% CI 1.66 to 2.76; p<0.001). In the matched subset, 22% of warfarinised trauma patients died compared with 16.3% of non-warfarinised trauma patients with comparable age, injury severity and GCS (adjusted OR 1.94; 95% CI 1.25 to 3.01; p=0.003)., Conclusions: Preinjury warfarin use has been demonstrated to be an independent predictor of mortality in trauma patients. Clinicians managing major trauma patients on warfarin need to be aware of the vulnerability of this group., (Published by the BMJ Publishing Group Limited.

Background: Prediction models for trauma outcome routinely control for age but there is uncertainty about the need to control for comorbidity and whether the two interact. This paper describes recent revisions to the Trauma Audit and Research Network (TARN) risk adjustment model designed to take account of age and comorbidities. In addition linkage between TARN and the Office of National Statistics (ONS) database allows patient's outcome to be accurately identified up to 30 days after injury. Outcome at discharge within 30 days was previously used., Methods: Prospectively collected data between 2010 and 2013 from the TARN database were analysed. The data for modelling consisted of 129 786 hospital trauma admissions. Three models were compared using the area under the receiver operating curve (AuROC) for assessing the ability of the models to predict outcome, the Akaike information criteria to measure the quality between models and test for goodness-of-fit and calibration. Model 1 is the current TARN model, Model 2 is Model 1 augmented by a modified Charlson comorbidity index and Model 3 is Model 2 with ONS data on 30 day outcome., Results: The values of the AuROC curve for Model 1 were 0.896 (95% CI 0.893 to 0.899), for Model 2 were 0.904 (0.900 to 0.907) and for Model 3 0.897 (0.896 to 0.902). No significant interaction was found between age and comorbidity in Model 2 or in Model 3., Conclusions: The new model includes comorbidity and this has improved outcome prediction. There was no interaction between age and comorbidity, suggesting that both independently increase vulnerability to mortality after injury., (Published by the BMJ Publishing Group Limited.
