RESUMO
OBJECTIVE: To describe hospital admissions associated with SARS-CoV-2 infection in children and adolescents. DESIGN: Cohort study of 3.2 million first ascertained SARS-CoV-2 infections using electronic health care record data. SETTING: England, July 2020 to February 2022. PARTICIPANTS: About 12 million children and adolescents (age <18 years) who were resident in England. MAIN OUTCOME MEASURES: Ascertainment of a first SARS-CoV-2 associated hospital admissions: due to SARS-CoV-2, with SARS-CoV-2 as a contributory factor, incidental to SARS-CoV-2 infection, and hospital acquired SARS-CoV-2. RESULTS: 3 226 535 children and adolescents had a recorded first SARS-CoV-2 infection during the observation period, and 29 230 (0.9%) infections involved a SARS-CoV-2 associated hospital admission. The median length of stay was 2 (interquartile range 1-4) days) and 1710 of 29 230 (5.9%) SARS-CoV-2 associated admissions involved paediatric critical care. 70 deaths occurred in which covid-19 or paediatric inflammatory multisystem syndrome was listed as a cause, of which 55 (78.6%) were in participants with a SARS-CoV-2 associated hospital admission. SARS-CoV-2 was the cause or a contributory factor in 21 000 of 29 230 (71.8%) participants who were admitted to hospital and only 380 (1.3%) participants acquired infection as an inpatient and 7855 (26.9%) participants were admitted with incidental SARS-CoV-2 infection. Boys, younger children (<5 years), and those from ethnic minority groups or areas of high deprivation were more likely to be admitted to hospital (all P<0.001). The covid-19 vaccination programme in England has identified certain conditions as representing a higher risk of admission to hospital with SARS-CoV-2: 11 085 (37.9%) of participants admitted to hospital had evidence of such a condition, and a further 4765 (16.3%) of participants admitted to hospital had a medical or developmental health condition not included in the vaccination programme's list. CONCLUSIONS: Most SARS-CoV-2 associated hospital admissions in children and adolescents in England were due to SARS-CoV-2 or SARS-CoV-2 was a contributory factor. These results should inform future public health initiatives and research.

AIM: We describe approaches to steroid therapy use in paediatric multisystem inflammatory syndrome temporally associated with SARS-CoV-2 (PIMS-TS) and examine the association between steroid therapy and key clinical markers of severity. METHODS: We conducted a retrospective review of children (<18 years) admitted to a tertiary paediatric hospital in the UK with PIMS-TS. We collected data on if and why steroid therapy was used; the duration, type and dosing of steroids prescribed; and approaches to hypothalamo-pituitary-adrenal (HPA) axis monitoring, if performed. We examined associations between steroid exposure/total steroid dose (mg/m2 /day) and paediatric intensive care unit admission, mechanical ventilation and inotropic support. RESULTS: Steroid therapy was commenced in most children (84.9%, n = 104) with a median total daily steroid dose (hydrocortisone equivalent) of 271.0 mg/m2 /day (interquartile range 232.5-355.5) and treatment length of 26.0 days (interquartile range 19.0-32.0). Dosing regimens predominantly involved a short course of high-dose methylprednisolone followed by tapering oral prednisolone. Basal and/or dynamic testing of the HPA axis was conducted in a minority (11.8%, n = 15) and was normal. Duration of steroid therapy correlated positively with durations of paediatric intensive care unit admission (r = 0.407, P < 0.001) and mechanical ventilation (r = 0.797, P < 0.001). A greater proportion of children receiving steroid therapy also received inotropic support compared to those that did not receive steroid therapy (71.4% vs. 45.5%, P = 0.025). CONCLUSION: Prolonged, high-dose steroid therapy is often used in the management of severe PIMS-TS with the potential for HPA axis suppression and should be withdrawn carefully.

BACKGROUND: Standards generally reported in the literature about informing children and respecting their consent or refusal before elective heart surgery may differ from actual practice. This research aims to summarize the main themes in the literature about paediatric anaesthesia and compare these with research findings on how health professionals counsel young children before elective heart surgery, respect their consent or refusal, and maintain patient-centred care. METHODS: This qualitative research involved: literature reviews about children's consent to surgery and major interventions; observations of wards, clinics and medical meetings in two paediatric cardiology departments, October 2019 to February 2020; audio-recorded semi-structured interviews with 45 hospital staff, including 5 anaesthetists, and related experts, November 2019 to April 2021; interviews with 16 families, with children aged 6- to 15-years and their parents shortly after elective heart surgery, and some months later (reported in other papers); thematic data analysis; and research reports on how different professions contribute to children's informed decisions for heart surgery. RESULTS: The medical, ethics and English legal literature tend to assume legal minors cannot refuse major recommended treatment, and cannot consent until they are 12 years or older. Little is said about informing pre-competent children. If children resist, some anaesthetists rely on sedation and distraction, and avoid much informed discussion, aiming to reduce peri-operative anxiety. However, interviewees reported informing young children, and respecting their consent or refusal before elective surgery. They may delay elective surgery and provide further information and support, aiming to reduce fear and promote trust. Six years of age was commonly cited as the threshold for respecting consent to heart transplantation. CONCLUSION: Differing views about younger children's competence, anxiety and best interests support different reactions to children's consent and refusal before elective heart surgery. This paper reports the zero-restraint policy followed for over a decade in at least one leading surgery centre. The related law and literature need to be updated, to take more account of evidence of actual practice.

BACKGROUND: The law and literature about children's consent generally assume that patients aged under-18 cannot consent until around 12 years, and cannot refuse recommended surgery. Children deemed pre-competent do not have automatic rights to information or to protection from unwanted interventions. However, the observed practitioners tend to inform young children s, respect their consent or refusal, and help them to "want" to have the surgery. Refusal of heart transplantation by 6-year-olds is accepted. RESEARCH QUESTION: What are possible reasons to explain the differences between theories and practices about the ages when children begin to be informed about elective heart surgery, and when their consent or refusal begins to be respected? RESEARCH DESIGN, PARTICIPANTS AND CONTEXT: Research methods included reviews of related healthcare, law and ethics literature; observations and conversations with staff and families in two London hospitals; audio-recorded semi-structured interviews with a purposive sample of 45 healthcare professionals and related experts; interviews and a survey with parents and children aged 6- to 15-years having elective surgery (not reported in this paper); meetings with an interdisciplinary advisory group; thematic analysis of qualitative data and co-authorship of papers with participants. ETHICAL CONSIDERATIONS: Approval was granted by four research ethics committees/authorities. All interviewees gave their informed written consent. FINDINGS: Interviewees explained their views and experiences about children's ages of competence to understand and consent or refuse, analysed by their differing emphases on informed, signified or voluntary consent. DISCUSSION: Differing views about children's competence to understand and consent are associated with emphases on consent as an intellectual, practical and/or emotional process. Conclusion: Greater respect for children's practical signified, emotional voluntary and intellectual informed consent can increase respectful understanding of children's consent. Nurses play a vital part in children's practitioner-patient relationships and physical care and therefore in all three elements of consent.

BACKGROUND: Paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS) is a rare complication of SARS-CoV-2 associated with single or multiorgan dysfunction. OBJECTIVE: We aimed to evaluate the incidence of acute kidney injury (AKI) and risk factors for kidney dysfunction in PIMS-TS, with reporting of 6-month renal follow-up data. We also evaluated renal involvement between first and second waves of the SARS-CoV-2 pandemic in the UK, the latter attributed to the Alpha variant. DESIGN: A single-centre observational study was conducted through patient chart analysis. SETTING: Data were collected from patients admitted to Great Ormond Street Hospital, London, UK, between April 2020 and March 2021. PATIENTS: 110 patients <18 years of age. MAIN OUTCOME MEASURE: AKI during hospitalisation. AKI classification was based on upper limit of reference interval (ULRI) serum creatinine (sCr) values. RESULTS: AKI occurred in 33 (30%) patients. Hypotension/hypoperfusion was associated with almost all cases. In univariate analysis, the AKI cohort had higher peak levels of triglycerides (OR, 1.27 (95% CI, 1.05 to 1.6) per 1 mmol/L increase) and C reactive protein (OR, 1.06 (95% CI, 1.02 to 1.12) per 10 mg/L increase), with higher requirement for mechanical ventilation (OR, 3.8 (95% CI, 1.46 to 10.4)) and inotropic support (OR, 15.4 (95% CI, 3.02 to 2.81)). In multivariate analysis, triglycerides were independently associated with AKI stages 2-3 (adjusted OR, 1.26 (95% CI, 1.04 to 1.6)). At follow-up, none had macroalbuminuria and all had sCr values Assuntos

RESUMO
OBJECTIVES: To 1) analyze the short-term biochemical improvements and clinical outcomes following treatment of children with post-severe acute respiratory syndrome coronavirus-2 inflammatory syndrome (multisystem inflammatory syndrome in children/pediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome coronavirus-2) admitted to U.K. PICUs and 2) collate current treatment guidance from U.K. PICUs. DESIGN: Multicenter observational study. SETTING: Twenty-one U.K. PICUs. PATIENTS: Children (< 18 yr) admitted to U.K. PICUs between April 1, 2020, and May 10, 2020, fulfilling the U.K. case definition of pediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome coronavirus-2. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Routinely collected, deidentified data were analyzed. Propensity score and linear mixed effects models were used to analyze the effect of steroids, IV immunoglobulin, and biologic agents on changes in C-reactive protein, platelet counts, and lymphocyte counts over the course of PICU stay. Treatment recommendations from U.K. clinical guidelines were analyzed. Over the 6-week study period, 59 of 78 children (76%) received IV immunoglobulin, 57 of 78 (73%) steroids, and 18 of 78 (24%) a biologic agent. We found no evidence of a difference in response in clinical markers of inflammation between patients with multisystem inflammatory syndrome in children/pediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome coronavirus-2 who were treated with IV immunoglobulin, steroids, or biologics, compared with those who were not. By the end of the study period, most patients had received immunomodulation. The 12 patients who did not receive any immunomodulators had similar decrease in inflammatory markers as those treated. Of the 14 guidelines analyzed, the use of IV immunoglobulin, steroids, and biologics was universally recommended. CONCLUSIONS: We were unable to identify any short-term benefit from any of the treatments, or treatment combinations, administered. Despite a lack of evidence, treatment guidelines for multisystem inflammatory syndrome in children/pediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome coronavirus-2 have become very similar in advising step-wise treatments. Retaining clinical equipoise regarding treatment will allow clinicians to enroll children in robust clinical trials to determine the optimal treatment for this novel important condition.

OBJECTIVES: To study the prevalence, evolution, and clinical factors associated with acute kidney injury in children admitted to PICUs with pediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome coronavirus-2. DESIGN: Multicenter observational study. SETTING: Fifteen PICUs across the United Kingdom. PATIENTS: Patients admitted to United Kingdom PICUs with pediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome coronavirus-2 between March 14, 2020, and May 20, 2020. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Deidentified data collected as part of routine clinical care were analyzed. All children were diagnosed and staged for acute kidney injury based on the level of serum creatinine above the upper limit of reference interval values according to published guidance. Severe acute kidney injury was defined as stage 2/3 acute kidney injury. Uni- and multivariable analyses were performed to study the association between demographic data, clinical features, markers of inflammation and cardiac injury, and severe acute kidney injury. Over the study period, 116 patients with pediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome coronavirus-2 were admitted to 15 United Kingdom PICUs. Any-stage acute kidney injury occurred in 48 of 116 patients (41.4%) and severe acute kidney injury in 32 of 116 (27.6%) patients, which was mostly evident at admission (24/32, 75%). In univariable analysis, body mass index, hyperferritinemia, high C-reactive protein, Pediatric Index of Mortality 3 score, vasoactive medication, and invasive mechanical ventilation were associated with severe acute kidney injury. In multivariable logistic regression, hyperferritinemia was associated with severe acute kidney injury (compared with nonsevere acute kidney injury; adjusted odds ratio 1.04; 95% CI, 1.01-1.08; p = 0.04). Severe acute kidney injury was associated with longer PICU stay (median 5 days [interquartile range, 4-7 d] vs 3 days [interquartile range, 1.5-5 d]; p < 0.001) and increased duration of invasive mechanical ventilation (median 4 days [interquartile range, 2-6 d] vs 2 days [interquartile range, 1-3 d]; p = 0.04). CONCLUSIONS: Severe acute kidney injury occurred in just over a quarter of children admitted to United Kingdom PICUs with pediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome coronavirus-2. Hyperferritinemia was significantly associated with severe acute kidney injury. Severe acute kidney injury was associated with increased duration of stay and ventilation. Although short-term outcomes for acute kidney injury in pediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome coronavirus-2 appear good, long-term outcomes are unknown.

We describe the adaptive coping strategies required in the management of a heterogeneous group of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pediatric patients. The diverse range of presentations, presenting in distinct phenotypic waves, exemplified the importance of preparedness for the unknown. Lessons learned will be essential in planning for a likely second wave of SARS-CoV-2.

BACKGROUND: In April, 2020, clinicians in the UK observed a cluster of children with unexplained inflammation requiring admission to paediatric intensive care units (PICUs). We aimed to describe the clinical characteristics, course, management, and outcomes of patients admitted to PICUs with this condition, which is now known as paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS). METHODS: We did a multicentre observational study of children (aged <18 years), admitted to PICUs in the UK between April 1 and May 10, 2020, fulfilling the case definition of PIMS-TS published by the Royal College of Paediatrics and Child Health. We analysed routinely collected, de-identified data, including demographic details, presenting clinical features, underlying comorbidities, laboratory markers, echocardiographic findings, interventions, treatments, and outcomes; serology information was collected if available. PICU admission rates of PIMS-TS were compared with historical trends of PICU admissions for four similar inflammatory conditions (Kawasaki disease, toxic shock syndrome, haemophagocytic lymphohistiocytosis, and macrophage activation syndrome). FINDINGS: 78 cases of PIMS-TS were reported by 21 of 23 PICUs in the UK. Historical data for similar inflammatory conditions showed a mean of one (95% CI 0·85-1·22) admission per week, compared to an average of 14 admissions per week for PIMS-TS and a peak of 32 admissions per week during the study period. The median age of patients was 11 years (IQR 8-14). Male patients (52 [67%] of 78) and those from ethnic minority backgrounds (61 [78%] of 78) were over-represented. Fever (78 [100%] patients), shock (68 [87%]), abdominal pain (48 [62%]), vomiting (49 [63%]), and diarrhoea (50 [64%]) were common presenting features. Longitudinal data over the first 4 days of admission showed a serial reduction in C-reactive protein (from a median of 264 mg/L on day 1 to 96 mg/L on day 4), D-dimer (4030 µg/L to 1659 µg/L), and ferritin (1042 µg/L to 757 µg/L), whereas the lymphocyte count increased to more than 1·0â×â109 cells per L by day 3 and troponin increased over the 4 days (from a median of 157 ng/mL to 358 ng/mL). 36 (46%) of 78 patients were invasively ventilated and 65 (83%) needed vasoactive infusions; 57 (73%) received steroids, 59 (76%) received intravenous immunoglobulin, and 17 (22%) received biologic therapies. 28 (36%) had evidence of coronary artery abnormalities (18 aneurysms and ten echogenicity). Three children needed extracorporeal membrane oxygenation, and two children died. INTERPRETATION: During the study period, the rate of PICU admissions for PIMS-TS was at least 11-fold higher than historical trends for similar inflammatory conditions. Clinical presentations and treatments varied. Coronary artery aneurysms appear to be an important complication. Although immediate survival is high, the long-term outcomes of children with PIMS-TS are unknown. FUNDING: None.

Dispersal has important ecological and evolutionary consequences for populations, but understanding the role of specific traits in dispersal can be difficult and requires careful experimentation. Moreover, understanding how humans alter dispersal is an important question, especially on oceanic islands where anthropogenic disturbance through species introductions can dramatically alter native ecosystems.In this study, we investigated the functional role of spines in seed dispersal of the plant caltrop (Tribulus cistoides L., Zygophyllaceae) by anthropogenic dispersal agents. We also tested whether humans or wildlife are more important seed dispersers of T. cistoides on the Galápagos. Tribulus cistoides is found on tropical mainland and oceanic island habitats. The dispersal structure of T. cistoides is called a mericarp, and they are typically protected by one pair of upper spines and a second pair of lower spines, but the presence and size of spines varies within and between populations. On the Galápagos, the upper and lower spines protect mericarps from seed predation by Darwin's finches. We tested whether spines play a dual role in dispersal by factorially manipulating the presence/absence of the upper and lower spines to simulate natural variation in mericarp morphology.The upper spines greatly facilitated seed dispersal, whereas the lower spines had no discernible effect on dispersal. The presence of upper spines increased dispersal rate on shoes by pedestrians 23-fold, on fabrics (e.g., towels) and cars by nearly twofold, and the presence of upper spines increased dispersal distance by cars sixfold. When comparing dispersal rates in habitats with high (roads and foot paths) versus low (arid forest) anthropogenic activity, dispersal rates were demonstrably higher in the habitats with more human activity.These results have important implications for understanding the ecology and evolution of plant dispersal in the Anthropocene. Spines on the fruits of T. cistoides play important functional roles in anthropogenic dispersal, whereas native and introduced wildlife plays a minor role in dispersal on inhabited islands of the Galápagos. Our results imply that seed predators and humans are jointly shaping the ecology and evolution of contemporary populations of T. cistoides on the Galápagos.
RESUMO
BACKGROUND: Postoperative sore throat is common after general anesthesia. The incidence in pediatric anesthesia is variable, and the etiology unclear. Establishing risk factors would enable prevention and could improve quality of care. AIMS: We performed a prospective single-center cohort study aiming to establish the incidence of postoperative sore throat in children undergoing GA with an endotracheal tube or laryngeal mask airway. Secondary aims were to identify independent risk factors for sore throat and the incidence of other postoperative complications including stridor, laryngospasm, nausea and vomiting, and delayed oral intake. METHODS: Between November 2017 and April 2018, perioperative data were collected from children aged 5-16 years undergoing general, plastic, urology, renal, and orthopedic surgery. Patients completed a postoperative questionnaire within 24 hours of surgery. RESULTS: We screened 334 children for inclusion at a tertiary pediatric hospital in the United Kingdom. One hundred and ninety-seven patients were included in the final analysis. The frequency of postoperative sore throat was 36.5%. Stridor occurred in 1.5%, laryngospasm 1.0%, postoperative nausea 59.4%, vomiting in recovery 4.6%, and delayed oral intake due to postoperative sore throat 30%. Nausea, vomiting, thirst, and pain were associated with a sore throat. Univariate analysis showed anesthesia longer than 2 hours, and use of an endotracheal tube was statistically associated with higher risk of sore throat. Over 50% of children with an endotracheal tube cuff pressure <20 cmH2 O had a postoperative sore throat. CONCLUSION: Postoperative sore throat is common in children. Endotracheal intubation is associated with a greater incidence than laryngeal mask airway use. A high rate of postoperative sore throat in children with endotracheal tube cuff pressures within the recommended range suggests multifactorial etiology. To confirm validity of the identified risk factors, we would recommend a larger prospective multi-center study.

Airway management in children is associated with anatomical and physiological challenges compared with adults. Pierre Robin sequence (PRS) is a condition characterized by micrognathia, glossoptosis, and cleft palate and related to a difficult airway. Both the Airtraq™ and GlideScope® have never been previously directly compared in PRS. Our aim was to evaluate the performance of these two airway devices in a PRS manikin for ethical and practical reasons. Between April and July 2017, 26, pediatric intensive care clinical fellows or trainees from a tertiary pediatric center were recruited to participate. In this prospective and randomized crossover trial, all participants first set up the Airtraq™ and the GlideScope® and then used these videolaryngoscopes to intubate an AirSim® PRS manikin. Our primary outcome measure was the duration of the successful intubation attempt. Duration of the successful intubation attempt was 18.1 (14.2-34.9 [10.2-51.3]) s for the Airtraq™ compared to 31.1 (18.7-55.6 [6.2-119]) s for the GlideScope® (p = 0.045). Setup time was 50.0 ± 6.9 s for the Airtraq™ and 27.8 ± 8.6 s for the GlideScope® (p < 0.001).Conclusion: Even though setup time was longer, the characteristics of intubation performance were superior with the Airtraq™ relative to the GlideScope® in an AirSim® PRS manikin. What is Known: ⢠Several case reports have described the successful use of Airtraq™ to intubate children with Pierre Robin sequence. ⢠The GlideScope® has demonstrated similar rates of first-attempt successful intubation to flexible fiberoptic bronchoscopy in a Pierre Robin sequence manikin. What is New: ⢠In the hands of pediatric non-airway specialists, the characteristics of intubation performance, including the duration of the successful intubation attempt, are superior with the Airtraq™ compared with the GlideScope® in a Pierre Robin sequence manikin. ⢠Setup time for the Airtraq™ is, however, longer relative to that for the GlideScope®.

BACKGROUND: Nasopharygeal airways are used in urgent situations to alleviate airway obstruction. Guidelines for measuring the length of the NPA differ between national and international guidelines, and the evidence base for these measurements is lacking. The purpose of this study was to measure the nares-epiglottis and nares-vocal cord distances in young children (neonates to 12 years) on 3D reconstructed Magnetic Resonance Imaging (MRI) brain volume scans, and to examine the relationship of these distances with the nares-tragus and nares-mandible distances. METHOD: One-hundred and seventy-six scans were reviewed. All patients had undergone MRI 3D brain volume imaging. The anatomical landmarks were identified and the nares-tragus, nares-mandible distances measured and compared to nares-epiglottis and nares-vocal cord distance using Osirix. RESULTS: The nares-epiglottis and nares-vocal cords distances significantly correlated (p-value <0.05). The nares-tragus distance showed strong correlation with the nares-epiglottis and nares-vocal cord distance compared to the nares-mandible distance (p-value <0.05). CONCLUSION: In conclusion, the length of a nasopharyngeal airway in children under the age of twelve years can be predicted using the nares-tragus external anatomical distance minus 10 mm.

OBJECTIVES: To evaluate the effectiveness of two scoring systems, the inadequate oxygen delivery index, a risk analytics algorithm (Etiometry, Boston, MA) and the Low Cardiac Output Syndrome Score, in predicting adverse events recognized as indicative of low cardiac output syndrome within 72 hours of surgery. DESIGN: A retrospective observational pair-matched study. SETTING: Tertiary pediatric cardiac ICU. PATIENTS: Children undergoing cardiac bypass for congenital heart defects. Cases experienced an adverse event linked to low cardiac output syndrome in the 72 hours following surgery (extracorporeal membrane oxygenation, renal replacement therapy, cardiopulmonary resuscitation, and necrotizing enterocolitis) and were matched with a control patient on criteria of procedure, diagnosis, and age who experienced no such event. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of a total 536 bypass operations in the study period, 38 patients experienced one of the defined events. Twenty-eight cases were included in the study after removing patients who suffered an event after 72 hours or who had insufficient data. Clinical and laboratory data were collected to derive scores for the first 12 hours after surgery. The inadequate oxygen delivery index was calculated by Etiometry using vital signs and laboratory data. A modified Low Cardiac Output Syndrome Score was calculated from clinical and therapeutic markers. The mean inadequate oxygen delivery and modified Low Cardiac Output Syndrome Score were compared within each matched pair using the Wilcoxon signed-rank test. Inadequate oxygen delivery correctly differentiated adverse events in 13 of 28 matched pairs, with no evidence of inadequate oxygen delivery being higher in cases (p = 0.71). Modified Low Cardiac Output Syndrome Score correctly differentiated adverse events in 23 of 28 matched pairs, with strong evidence of a raised score in low cardiac output syndrome cases (p < 0.01). CONCLUSIONS: Although inadequate oxygen delivery is an Food and Drug Administration approved indicator of risk for low mixed venous oxygen saturation, early postoperative average values were not linked with medium-term adverse events. The indicators included in the modified Low Cardiac Output Syndrome Score had a much stronger association with the specified adverse events.

The National Confidential Enquiry into Patient Outcomes and Death (NCEPOD) report 'Time to Intervene' (2012) stated that in a substantial number of cases, resuscitation is attempted when it was thought a 'do not attempt cardiopulmonary resuscitation' (DNACPR) decision should have been in place. Early decisions about CPR status and advance planning about limits of care now form part of national recommendations by the UK Resuscitation Council (2016). Treatment escalation plans (TEP) document what level of treatment intervention would be appropriate if a patient were to become acutely unwell and were not previously formally in place at King's College Hospital. A unifying paper based form was successfully piloted in the Acute Medical Unit, introducing the TEP and bringing together decision making around both treatment escalation and CPR status. Subsequently an electronic order-set for CPR status and treatment escalation was launched in April 2015 which led to a highly visible CPR and escalation status banner on the main screen at the top of the patient's electronic record. Ultimately due to further iterations in the electronic process by December 2016, all escalation decisions for acutely admitted patients now have high quality supporting, explanatory documentation with 100% having TEPs in place. There is now widespread multidisciplinary engagement in the process of defining limits of care for acutely admitted medical patients within the first 14 hours of admission and a strategy for rolling this process out across all the divisions of the hospital through our Deteriorating Patient Group (DPG). The collaborative design with acute medical, palliative and intensive care teams and the high visibility provided by the electronic process in the Electronic Patient Record (EPR) has enhanced communication with these teams, patients, nursing staff and the multidisciplinary team by ensuring clarity through a universally understood process about escalation and CPR. Clarity and openness about these discussions have been welcomed by patient focus groups facilitated via our acute medicine patient experience committee. There has been a shift in medical culture where transparency about limits of care has contributed to improving patient safety and quality of care through reducing unnecessary CPR supported by focus groups of staff.
