RESUMO
OBJECTIVE: This study describes the baseline clinical characteristics, predictors of successful extubation at referring hospitals and short-term outcomes of children intubated for status epilepticus and referred to United Kingdom (UK) paediatric critical care transport teams (PCCTs). DESIGN: Multicentre audit with case-control analysis, conducted between 1 September 2018 and 1 September 2020. SETTING: This study involved 10 UK PCCTs. PATIENTS: Children over 1 month of age intubated during emergency management for status epilepticus (SE), referred to UK PCCTs. Patients with trauma, requiring time-critical neurosurgical intervention or those with a tracheostomy were excluded. INTERVENTIONS: No interventions were implemented. MEASUREMENTS AND MAIN RESULTS: Out of the 1622 referrals for SE, 1136 (70%) were intubated at referral. The median age was 3 years (IQR 1.25-6.54 years). Among the intubated children, 396 (34.8%) were extubated locally by the referring team, with 19 (4.8%) requiring reintubation. Therefore, the overall rate of successful extubation was 33% (377/1136). There was significant variation between PCCTs, with local extubation rates ranging from 2% to 74%. Multivariable analyses showed region/PCCT, contributing diagnosis, acute changes on CT, preceding encephalopathy and type of continuous sedation (midazolam) used postintubation were significantly associated with transfer to a critical care unit. CONCLUSION: This study highlights wide regional variation in early extubation practices. Regions with high successful extubation rates have established extubation guidelines from PCCTs. Successful extubation represents critical care transports that have been avoided.

OBJECTIVE: To determine whether artificial intelligence (AI) can generate plausible and engaging titles for potential Christmas research articles in The BMJ. DESIGN: Observational study. SETTING: Europe, Australia, and Africa. PARTICIPANTS: 1 AI technology (Generative Pre-trained Transformer 3, GPT-3) and 25 humans. MAIN OUTCOME MEASURES: Plausibility, attractiveness, enjoyability, and educational value of titles for potential Christmas research articles in The BMJ generated by GPT-3 compared with historical controls. RESULTS: AI generated titles were rated at least as enjoyable (159/250 responses (64%) v 346/500 responses (69%); odds ratio 0.9, 95% confidence interval 0.7 to 1.2) and attractive (176/250 (70%) v 342/500 (68%); 1.1, 0.8 to 1.4) as real control titles, although the real titles were rated as more plausible (182/250 (73%) v 238/500 (48%); 3.1, 2.3 to 4.1). The AI generated titles overall were rated as having less scientific or educational merit than the real controls (146/250 (58%) v 193/500 (39%); 2.0, 1.5 to 2.6); this difference, however, became non-significant when humans curated the AI output (146/250 (58%) v 123/250 (49%); 1.3, 1.0 to 1.8). Of the AI generated titles, the most plausible was "The association between belief in conspiracy theories and the willingness to receive vaccinations," and the highest rated was "The effects of free gourmet coffee on emergency department waiting times: an observational study." CONCLUSIONS: AI can generate plausible, entertaining, and scientifically interesting titles for potential Christmas research articles in The BMJ; as in other areas of medicine, performance was enhanced by human intervention.

PURPOSE: In the United Kingdom, critically ill adolescents are treated in either adult or pediatric intensive care units (AICUs or PICUs). This study explores staff perspectives on where and how best to care for this distinct group. MATERIALS AND METHODS: Semistructured interviews were conducted with 12 members of staff (3 medical, 6 nursing, and 3 allied health professionals) working in 4 ICUs; 2 general hospital AICUs and 2 tertiary centre-based PICUs in England. Interviews were audio-recorded, transcribed, and analyzed using framework analysis. FINDINGS: One overarching theme was identified, reflecting staff understanding of the term "adolescent," and this was linked to 2 further themes, each of which had several subthemes. "Needs of the critically ill adolescent" included medical needs, dignity and privacy, issues around consent, and the impact of intensive care admission. "Implications for staff" included managing parental presence and lack of familiarity, and emotional impact, of dealing with this patient group. Some of these factors are currently better accommodated in adult settings. CONCLUSIONS: Decision-making about the place of care should take into account the individual circumstances of the patient (e.g., nature of their medical condition and previous experiences, maturity, family preference) and not be based only on age at admission. We should work across disciplines to ensure we can discover, and consistently deliver, best practice to meet the needs of critically ill adolescents.

OBJECTIVE: Estimating weight is essential in order to prepare appropriate sized equipment and doses of resuscitation drugs in cases where children are critically ill or injured. Many methods exist with varying degrees of complexity and accuracy. The most recent version of the Advanced Paediatric Life Support (APLS) course has changed their teaching from an age-based calculation method to the use of a reference table. We aimed to evaluate the potential implications of this change. METHOD: Using a bespoke online simulation platform we assessed the ability of acute paediatric staff to apply different methods of weight estimation. Comparing the time taken, rate and magnitude of errors were made using the APLS single and triple age-based formulae, Best Guess and reference table methods. To add urgency and an element of cognitive stress, a time-based competitive component was included. RESULTS: 57 participants performed a total of 2240 estimates of weight. The reference table was the fastest (25 (22-28) vs 35 (31-38) to 48 (43-51) s) and most preferred, but errors were made using all methods. There was no significant difference in the percentage accuracy between methods (93%-97%) but the magnitude of errors made was significantly smaller using the three APLS formulae 10% (6.5-21) compared with reference table (69% (34-133)) mainly from month/year table confusion. CONCLUSION: In this exploratory study under psychological stress none of the methods of weight estimation were free from error. Reference tables were the fastest method and also had the largest errors and should be designed to minimise the risk of picking errors.

OBJECTIVES: To describe the case mix, resource use and outcomes for adolescents admitted to intensive care units in the UK. METHODS: Analysis of national prospectively collected data for all adolescents aged 12-19 years admitted to UK adult or paediatric intensive care units. RESULTS: There were 37,320 admissions of adolescents during the eight-year study period. Excluding elective surgery, respiratory diagnoses were the most common reason for paediatric intensive care unit (PICU) admission, with trauma and intoxication the most common reasons for adult intensive care unit (AICU) admission. Intensive care unit mortality was 6.0% and 5.7% for those admitted to PICUs and AICUs, respectively. CONCLUSIONS: Mortality is similar among adolescents admitted to AICUs and PICUs; however, these rates have not been corrected for severity of acute illness or underlying burden of chronic illness, which may be different between AICUs and PICUs. Services planned for the majority of AICU and PICU patients may not be optimal for critically ill adolescents treated in UK intensive care units, who may need special consideration.
RESUMO
OBJECTIVES: To determine the incidence of vocal cord paresis (VCP) after neonatal aortic arch repair/Norwood-type procedure, and the effectiveness of noninvasive laryngeal ultrasound in detecting VCP compared with gold standard invasive nasoendoscopy. METHODS: Fifty-two patients who underwent an arch repair (39 of 52; 75%) or Norwood-type procedure (13 of 52; 25%) via sternotomy between April 1, 2015, and April 30, 2017 underwent laryngeal ultrasound (50 of 52; 96%) and/or flexible fiber optic nasoendoscopy (39 of 52; 75%) at 48 to 72 hours after endotracheal extubation. Primary arch diagnoses were coarctation in 56% (29 of 52), hypoplastic left heart syndrome in 17% (9 of 52), isolated hypoplastic arch in 17% (9 of 52), and interrupted aortic arch in 10% (5 of 52). The median patient age at surgery was 5.5 days (interquartile range, 4.0-12.5 days). Fifteen patients (15 of 52; 29%) required preoperative intubation. RESULTS: Left VCP was present in 59% (23 of 39) of patients on nasoendoscopy and in 59% (27 of 46) of patients on laryngeal ultrasound, and 4 additional patients had inconclusive ultrasound results. There was agreement between the results of nasoendoscopy and conclusive ultrasound in all cases. The overall sensitivity, specificity, positive and negative predictive values, and Cohen's kappa coefficient of laryngeal ultrasound compared with nasoendoscopy for the detection of left VCP were 95%, 88%, 91%, 93%, and 0.83, respectively. On multivariable analysis, preoperative intubation and arch repair techniques other than the Norwood procedure were associated with left VCP (odds ratio, 12.7; P = .03; and 14.1; P = .03, respectively). CONCLUSIONS: There is a high incidence of VCP after arch repair via sternotomy. Laryngeal ultrasound seems to be an effective and noninvasive method for detecting VCP in neonates and young children.

Critically ill adolescents are usually treated on intensive care units optimised for much older adults or younger children. The way they access and experience health services may be very different to most adolescent service users, and existing quality criteria may not apply to them. The objectives of this pilot study were, firstly, to determine whether adolescents and their families were able to articulate their experiences of their critical care admission and secondly, to identify the factors that are important to them during their intensive care unit (ICU) or high dependency unit (HDU) stay. Participants were 14-17 year olds who had previously had an emergency admission to an adult or paediatric ICU/HDU in one of four UK hospitals (two adult, two paediatric) and their parents. Semi-structured interviews were conducted with eight mother-adolescent dyads and one mother. Interviews were transcribed and analysed using framework analysis. CONCLUSION: The main reported determinant of high-quality care was the quality of interaction with staff. The significance of these interactions and their environment depended on adolescents' awareness of their surroundings, which was often limited in ICU and changed significantly over the course of their illness. Qualitative interview methodology would be difficult to scale up for this group. What is known ⢠Critically ill adolescents are usually treated on intensive care units optimised for older adults or younger children. ⢠The way they access and experience health services may be different to most adolescent patients; existing quality criteria may not apply. What is new ⢠Reported determinants of high-quality care were age-appropriateness of the environment, respectfulness and friendliness of staff, communication and inclusion in healthcare decisions. ⢠The significance of these depended on adolescents' awareness of their surroundings, which was often limited and changed over the course of their illness.

PURPOSE: Tracheostomy is a common intervention for adults admitted to intensive care; many are performed early and most are percutaneous. Our study aimed to elucidate current practice and indications for children in the UK admitted to paediatric intensive care and undergoing tracheostomy. DESIGN: A questionnaire covering unit guidelines, practice, and the advantages and disadvantages of tracheostomy was sent to all UK paediatric intensive care units (PICUs) participating in the Paediatric Intensive Care Audit Network (PICANet). These results were combined with data from PICANet on all children in the UK reported to have had a tracheostomy performed during a PICU admission between 2005 and 2009 inclusive. RESULTS: Over 5 years, 1613 children had tracheostomies performed during their PICU admission (2.05% of all admissions). The death rate was 5.58% with tracheostomy versus 4.72% overall, but differences were not significant when risk-adjusted using the Paediatric Index of Mortality 2 (PIM2). All 29 units participating in PICANet responded to the survey. Prolonged invasive ventilation was an indication for tracheostomy in 25/29 units, but the definition varied between 14 and 90 days, and most respondents considered timing on an individual basis. Children undergoing tracheostomy during PICU admission account for 9% of PICU bed days in the UK. CONCLUSIONS: In contrast with current adult UK practice, tracheostomy for children admitted to intensive care is infrequent, performed late following admission and usually surgical. Practice varies significantly. The death rate for children having a tracheostomy performed was not significantly higher than for children admitted to PICU who did not undergo tracheostomy.

AIM: To quantify use of complementary and alternative medicine (CAM) in children with non-malignant, life-limiting illness. METHOD: A self-administered questionnaire was sent to families who received care from a community children's nursing and psychology team for children with non-malignant, life-limiting conditions. RESULTS: A total of 32 per cent of respondents had used up to seven types of CAM for their child and 43.4 per cent had used CAM for themselves or other family members. Most parents used CAM to enhance general wellbeing rather than treat specific diagnoses. A total of 58.3 per cent felt the therapy was helpful, 50 per cent had tried conventional medicine first, and 63.9 per cent of users discussed their use of CAM with a doctor or community nurse. CONCLUSION: The rate of CAM use is significantly higher in this population than found in many previous cross-sectional studies. This may reflect the different needs and expectations of families with children with non-malignant, life-limiting illnesses.

The margin of the temporal visual field lies more than 90° from the line of sight and is critical for detecting incoming threats and for balance and locomotive control. We show (i) contrast sensitivity beyond 70° is higher for moving stimuli than for stationary, and in the outermost region, only moving stimuli are visible; (ii) sensitivity is highest for motion in directions near the vertical and horizontal axes and is higher for forward than for backward directions; (iii) the former anisotropy arises early in the visual pathway; (iv) thresholds for discriminating direction are lowest for upward and downward motion.

OBJECTIVE: To find out whether doctors who work with children have a basic knowledge of tissue and organ donation which would allow them to initiate discussions with families. METHODS: Anonymous self-completed questionnaire containing basic information about donation administered to 56 doctors working in paediatrics, emergency medicine and intensive care in one district general hospital. RESULTS: 89% doctors were aware that children could donate solid organs after death although 39.3% thought incorrectly that premature babies were eligible. Respondents were generally less knowledgeable about age limits for tissue (heart valve and eye), blood and bone marrow donation. The overall average score on the questionnaire was only 49.9%, this score did not vary with grade or paediatric training. CONCLUSION: Participants had poor knowledge about tissue and organ donation, which would make approaching families difficult. This study has identified an important training need for all doctors involved in the care of dying children.
