Boldly going Introducing conflict management training to Starship Children's Hospital.

Conflict between health professionals and whanau (families) in paediatric hospitals is common and leads to significant distress for families and staff. The likelihood of challenges and conflict around communication and critical medical decision-making is increased where there are cultural and social complexities. Training staff to recognise and manage conflict as early as possible improves patient/whanau outcomes and staff well-being. This article describes an ongoing collaboration between Starship Children's Hospital in Auckland New Zealand (NZ) and the UK Medical Mediation Foundation (MMF) focused on educating staff in the early recognition and management of conflict using mediation skills. An evidence-based training programme and structured ongoing supervision of a small group of champions has enabled this training to be embedded into Starship clinical practice. The collaboration has included careful consideration of the New Zealand setting, ensuring that the content of the programme specifically addresses our unique cultural and social context. Mediation skills are an important step in ensuring that our patients and whanau feel heard, acknowledged, and respected, and contribute to the Starship Child Health's strategic priority of eliminating inequity and addressing institutional bias.

Characteristics and outcomes of human parechovirus infection in infants (2008-2012).

UNLABELLED: Human parechoviruses (HPeVs) cause a spectrum of disease ranging from self-limiting illness to severe disease and, sometimes, death. We describe the clinical characteristics and outcomes of HPeV infection in infants. The study describes the clinical and laboratory characteristics and outcomes of infants with HPeV infection during 2008-2012, from three paediatric hospitals in London each with a paediatric intensive care unit. The infants were retrospectively identified through laboratory and patient discharge databases and diagnosed through HPeV PCR. Fifty infants were identified. Half required admission to PICU. Infants less than 3 months were more likely to require PICU (16/25: p < 0.01). Clinical signs at presentation were often indistinguishable from those of bacterial sepsis and meningitis, but inflammatory markers were nearly always (95 % of cases) within normal ranges. Brain MRI showed white matter changes in 10/12 infants. Three of 19 infants with follow-up data (16 %) had significant neurological sequelae. CONCLUSION: HPeV may cause severe disease and long-term neurological sequelae in young infants. HPeV should be considered in infants with clinical features of sepsis/meningitis with normal CSF microscopy. Prospective observational studies are warranted to better define the epidemiology of infection and thus inform future treatment trials.

Fifteen minute consultation: managing neonatal and childhood herpes encephalitis.

Herpes simplex encephalitis (HSE) is the most common single cause of viral encephalitis in infants and children. Treated or untreated, it can be associated with considerable morbidity and mortality, and its presentation is usually insidious and non-specific. Prompt and careful investigation is important in order to establish the diagnosis so that treatment can be optimised. We address some common questions arising when diagnosing and treating presumed HSE throughout childhood.

N-methyl-D-aspartate receptor antibodies in post-herpes simplex virus encephalitis neurological relapse.

Herpes simplex virus encephalitis (HSVE) is a devastating condition that relapses, often with a chorea in children, despite adequate antiviral treatment. At relapse, evidence of viral replication is frequently absent, suggesting that the relapse may be immune-mediated. Seven children who had a neurological relapse following their initial encephalitis, identified from 20 cases of pediatric HSVE, were studied. Serum and/or cerebrospinal fluid (CSF) were tested for N-methyl-D-aspartate receptor (NMDAR) and other antibodies previously reported in central nervous system autoimmunity. Five of the 7 relapsing children had choreoathetosis; 2 of these were NMDAR antibody-positive, 2 were negative (1 with HSV-positive CSF), and 1 was not available for testing. An additional patient, who relapsed with cognitive regression but with no movement disorder, was also NMDAR antibody-positive. In 2 of the NMDAR antibody-positive patients who were treated at relapse and in 1 who was treated only after 10 years of having a relapsing encephalopathy, a beneficial response was observed. Neurological relapses after HSVE may frequently be immune-mediated, particularly in children with chorea. NMDAR antibodies are common, and immunotherapy may be beneficial.

Fifteen-minute consultation: a structured approach to the management of recurrent oral ulceration in a child.

OBJECTIVE: To present a structured approach for an outpatient consultation of a child with recurrent mouth ulcers. METHOD: Review of literature and description of approach followed in our unit. CONCLUSIONS: The literature emphasises the need to consider local and systemic causes for oral ulceration in a child. Focused history and examination are key in establishing the cause and in order to ensure appropriate management.

Comparing neonatal and paediatric antibiotic prescribing between hospitals: a new algorithm to help international benchmarking.

OBJECTIVES: The WHO anatomical therapeutic chemical (ATC)/defined daily dose (DDD) methodology is a standardized method of comparing antimicrobial use. The ATC/DDD is defined as the average maintenance daily dose of a drug used in a 70 kg adult, ignoring the considerable differences in body weight of neonates and children. The aim of this study was to develop a new standardized way of comparing rates of antimicrobial prescribing between European children's hospitals. METHODS: This pilot study at four European children's hospitals (in the UK, Greece and Italy) collected data including demographics, antibiotic use, dosing and indication in children and neonates over a 14 day period. RESULTS: A total of 1217 antibiotic prescriptions were issued with 47 different antibiotics used. Approximately half of all children and a third of all neonates received antibiotics, with wide variation between centres in the type and dose of antibiotic used. We propose a new pragmatic three-step algorithm. The first step includes a simple comparison of the proportion of hospitalized children on antibiotics by weight bands and the number of antimicrobials that account for 90% of total DDD drug usage (DU90%). The second step is a comparison of the dosing used (mg/kg/day). The third step is to compare overall drug exposure using DDD/100 bed days for standardized weight bands between centres. CONCLUSIONS: This novel method has the potential to be a useful tool to provide antibiotic use comparator data and requires validation in a large prospective point prevalence study.

Neurological complications of pandemic influenza A H1N1 2009 infection: European case series and review.

Neurological manifestations and outcomes of children with the 2009 H1N1 virus infection have been reported in three American series and from smaller cohorts and case reports worldwide. Of the 83 children admitted between April 2009 and March 2010 with H1N1 virus infection to a tertiary children's hospital in a European setting, five children aged between 2 and 10 years had neurological symptoms. Four patients had seizures and encephalopathy at presentation. One patient presented with ataxia; one developed neuropsychiatric manifestations, and two developed movement disorders during the disease course. Early neuroimaging showed evidence of acute necrotising encephalopathy (ANE) in one case and non-specific white matter changes in another. Initial neuroimaging was normal for the other three, but interval MRI showed increased signal in bilateral periventricular distribution in one and significant cerebral volume loss in the other. Clinical outcomes varied: two recovered fully while three had residual seizures and/or significant cognitive deficits. Conclusion An analysis of our patients along with all reported cases reveal that seizures and encephalopathy were common neurological presentations associated with pandemic 2009 H1N1 influenza virus infection in children requiring hospital admission. Neuroimaging suggestive of ANE, basal ganglia involvement and volume loss appears to be associated with worse neurological outcome.

Transforming training into practice with the conflict management framework: a mixed methods study.

Objective: To implement and evaluate the use of the conflict management framework (CMF) in four tertiary UK paediatric services. Design: Mixed methods multisite evaluation including prospective pre and post intervention collection of conflict data alongside semistructured interviews. Setting: Eight inpatient or day care wards across four tertiary UK paediatric services. Interventions: The two-stage CMF was used in daily huddles to prompt the recognition and management of conflict. Results: Conflicts were recorded for a total of 67 weeks before and 141 weeks after implementation of the CMF across the four sites. 1000 episodes of conflict involving 324 patients/families across the four sites were recorded. After implementation of the CMF, time spent managing episodes of conflict around the care of a patient was decreased by 24% (p<0.001) (from 73 min to 55 min) and the estimated cost of this staff time decreased by 20% (p<0.02) (from £26 to £21 sterling per episode of conflict). This reduction occurred despite conflict episodes after implementation of the CMF having similar severity to those before implementation. Semistructured interviews highlighted the importance of broad multidisciplinary leadership and training to embed a culture of proactive and collaborative conflict management. Conclusions: The CMF offers an effective adjunct to conflict management training, reducing time spent managing conflict and the associated staff costs.

Vici syndrome associated with sensorineural hearing loss and evidence of neuromuscular involvement on muscle biopsy.

Vici syndrome is a rare, genetically unresolved congenital multisystem disorder comprising agenesis of the corpus callosum, cataracts, immunodeficiency, cardiomyopathy, and hypopigmentation. An associated neuromuscular phenotype has not previously been described in detail. We report on an infant with clinical features suggestive of Vici syndrome and additional sensorineural hearing loss. Muscle biopsy revealed several changes including markedly increased variability in fiber size, increased internal nuclei, and abnormalities on Gomori trichrome and oxidative stains, raising a wide differential diagnosis including neurogenic atrophy, centronuclear myopathy (CNM) or a metabolic (mitochondrial) cytopathy. Respiratory chain enzyme studies, however, were normal and sequencing of common CNM-associated genes did not reveal any mutations. This case expands the clinical spectrum of Vici syndrome and indicates that muscle biopsy ought to be considered in infants presenting with suggestive clinical features. In addition, we suggest that Vici syndrome is considered in the differential diagnosis of infants presenting with congenital callosal agenesis and that additional investigation has to address the possibility of associated ocular, auditory, cardiac, and immunologic involvement when this radiologic finding is present.

Off-label antibiotic use in children in three European countries.

OBJECTIVE: Antibiotics are the drugs most frequently prescribed for children, and most of them lack patent protection. The aim of this study was to evaluate off-label antibiotic use in three European countries. METHODS: Data relating to all patients admitted to the neonatal intensive care units (NICUs) and paediatric wards of the participating centres were collected by the same investigator over a 2-week survey period between February and May 2009. The data included age, date of birth, weight, relevant medical history and diagnosis, together with details of all of the antibiotics prescribed (compound, route of administration, dose, and indication for use). RESULTS: The study involved 616 children (110 admitted to NICUs: 62 in the UK, 38 in Italy and 10 in Greece; 506 admitted to general paediatric wards: 265 in the UK, 94 in Italy and 147 in Greece). A total of 1,244 antibiotic prescriptions were issued (290 in NICUs and 954 in paediatric wards). The results showed that off-label antibiotic use is very common among European paediatric patients, with generally only slight, but sometimes significant differences between countries. However, this use relates almost exclusively to doses and indications, and rarely to age. The only antibiotics found to be used off-label in an age-related manner in paediatric clinical practice are meropenem for neonates and quinolones or linezolid for older children, which represent priorities for future studies. CONCLUSION: European-wide educational programmes are urgently needed to meet the objectives of improving paediatricians' working knowledge of the recommendations surrounding licensed antibiotics-use in children, and of reducing uncontrolled patterns of prescribing.

Tenofovir use in human immunodeficiency virus-1-infected children in the United kingdom and Ireland.

BACKGROUND: Tenofovir disoproxil fumarate (TDF) is neither licensed for use nor extensively studied in HIV-infected children. The only available formulation is an adult tablet, introducing the possibility of dosing errors in children. TDF interacts with other antiretrovirals and has been associated with decline in renal function and CD4 count. We describe the use of TDF in a cohort of HIV-1-infected children in the United Kingdom and Ireland. METHODS: Children ever prescribed TDF and followed in the Collaborative HIV Pediatric Study cohort since 2001 were included in analyses of dosing, adverse events, and virologic and immunologic response. Suspected adverse drug reactions to TDF reported to the Medicines and Healthcare products Regulatory Agency during the same time were also reviewed. RESULTS: One hundred fifty-nine of 1253 children had taken TDF. They were older and had clinically more advanced disease than the rest of the cohort. Eighteen percent received >120% and 37% received <80% of the suggested pediatric dose (8 mg/kg). Thirty-seven percent of new TDF regimens contained didanosine (ddI), though few since 2005. Twelve of 159 (7.5%) children experienced serious adverse events and stopped TDF permanently, 11 taking concurrent lopinavir-ritonavir, and 10 ddI; 5 had renal toxicity. Viral load suppressed to < or =50 copies/mL at 12 months in 38% of those starting TDF. Median increase in CD4 count at 12 months was +110 cells/mL (interquartile range, 9-270), but only 3 cells/mL in those taking concurrent ddI. CONCLUSIONS: TDF seems to be an effective antiretroviral drug in this pediatric cohort, although considerable underdosing and overdosing occurs. A small number of children experienced serious adverse events while taking TDF; half were renal toxicity, most associated with concurrent ddI and lopinavir-ritonavir use.

Reactivity of Routine HIV Antibody Tests in Children With Perinatally Acquired HIV-1 in England: Cross-sectional Analysis.

We assessed HIV antibody prevalence in children with perinatally acquired HIV in England. Eighteen percent (10/55) of those starting combination antiretroviral therapy <6 months of age were seronegative at median age 9.1 years and had lower viral load at diagnosis and combination antiretroviral therapy start and fewer viral rebounds, than 45 of 55 seropositives. Implications for patient selection for HIV cure research, and interpretation of routine antibody testing, are discussed.

Antimicrobial policies in the neonatal units of the United Kingdom and Republic of Ireland.

OBJECTIVES: To review antibiotic and antifungal policies in British and Irish neonatal units (NNUs). METHODS: A telephone survey was performed regarding empirical antimicrobial guidelines of NNUs in the UK and Republic of Ireland. RESULTS: The response rate was 91% (202 of 222 NNUs). The guidelines from all responding units covered group B Streptococcus and Escherichia coli, the most common causes of neonatal septicaemia and meningitis. However, 19% did not cover Listeria, the cause of meningitis in 5% to 7% of cases in England and Wales. Second-line recommendations varied greatly between units, with widespread use of broad-spectrum agents. Fungal prophylaxis and treatment guidelines were generally rudimentary. CONCLUSIONS: Empirical antimicrobial recommendations on many NNUs include broad-spectrum antibiotics without ensuring universal coverage of important pathogens. We raise concerns about the selection pressures exerted for resistant pathogens and invasive fungal disease, especially as few units specify fungal prophylaxis or treatment guidance. Development of rational guidelines for the UK and Irish neonatal units might help to optimize treatment while minimizing overuse of broad-spectrum agents.

Morbidity, mortality, and response to treatment by children in the United Kingdom and Ireland with perinatally acquired HIV infection during 1996-2006: planning for teenage and adult care.

BACKGROUND: Recent evidence suggests that decreases in morbidity and mortality in cohorts of adults infected with human immunodeficiency virus (HIV) are showing signs of reversal. We describe changes over time in these characteristics and in the response to treatment among children in the United Kingdom and Ireland with perinatally acquired HIV infection, many of whom are now adolescents. METHODS: We analyzed prospective cohort data reported to the National Study of HIV in Pregnancy and Childhood (NSHPC) and the Collaborative HIV Paediatric Study. RESULTS: By mid 2006, 1441 HIV-infected children were reported to NSHPC; 40% were > or = 10 years old at their most recent follow-up visit, and 34% were receiving care outside London. The proportion of children born abroad increased from 24% during 1994-1996 to 64% during 2003-2006. The percentage of total child time during which children received highly active antiretroviral therapy (HAART) increased from 36% during 1997-1999 to 61% during 2000-2002 and 63% during 2003-2006. Of children who were naive to antiretroviral therapy at the start of HAART, the percentage with an HIV-1 RNA load of < 400 copies/mL after 12 months increased from 52% during 1997-1999 to 79% during 2003-2006. In multivariate analysis, only calendar time predicted virological response, whereas both younger age and lower CD4 cell percentage at HAART initiation predicted increases of > 10% in the CD4 cell percentage. A total of 31% of children aged 5-14 years and 38% aged > or = 15 years at their most recent follow-up visit had been exposed to drugs from each of the 3 main HAART classes. The rate of AIDS and mortality combined decreased from 13.3 cases per 100 person-years before 1997 to 3.1 and 2.5 cases per 100 person-years, respectively, during 2000-2002 and 2003-2006; rates of hospital admission also declined during this interval. Of 18 children known to have died since 2003, 9 died within 1 month after presentation. CONCLUSIONS: Morbidity and mortality rates among HIV-infected children continue to decrease over time. Because these children are increasingly dispersed outside London, specialist care is now provided in national clinical networks. Transition pathways to adolescent and adult services and long-term observation to monitor the effects of prolonged exposure to both HIV and HAART are required.

Transient viral load increases in HIV-infected children in the U.K. and Ireland: what do they mean?

OBJECTIVES: To investigate transient increases in viral load during sustained suppression in children in the UK and Ireland Collaborative HIV Paediatric Study (CHIPS). DESIGN: Cohort of HIV-infected children from 39 centres. METHODS: Transient viraemia was defined as > or =1 detectable viral loads (> or =50 copies/ml) between two undetectable values (<50 copies/ml) <280 days apart, during a period of sustained viral suppression (from a confirmed level of <50 copies/ml until the last undetectectable measurement before antiretroviral therapy change or until a confirmed level of >50 copies/ml). RESULTS: Of 595 children initiating HAART without previous treatment, 347 (58%) achieved sustained suppression. Of these, 78 (23%) experienced 109 episodes of transient viraemia (median 134 copies/ml); 92 (84%) had levels of <1000 copies/ml (maximum 39,839). Transient viraemia was more common during second-line therapy (25/100 child-years [CY]) and following a previous episode (19/100 CY) compared with first-line therapy without a previous episode (11/100 CY). Rates decreased with age at HAART initiation (incidence rate ratio [IRR] 0.95 per year older; P = 0.05), but were higher in those suppressed for longer (IRR 1.63 in those suppressed for 21 year versus <1 year; P = 0.03). CD4+ and CD8+ T-cell counts were similar before and after transient viraemia. Of detectable viral loads during periods of suppression 44% were transient increases rather than virological failure: experiencing transient viraemia did not increase subsequent virological failure (P = 0.20). CONCLUSIONS: Transient viraemia is relatively common among children on HAART, occurring more frequently in those starting HAART at younger ages, on second-line therapy and after longer suppression. It does not appear to affect CD4+ or CD8+ T-cell counts or the risk of subsequent virological failure. Natural variation, assay effects and adherence might all have a role.

Conflict in a paediatric hospital: a prospective mixed-method study.

BACKGROUND: Conflict in healthcare is a well-recognised but under-examined phenomenon. Little is known about the prevalence and causes of conflict across paediatric specialties. OBJECTIVE: To report the frequency and characteristics of conflict in a paediatric hospital. DESIGN AND SETTING: An explanatory sequential mixed-method approach was adopted. A bespoke questionnaire recorded frequency, severity, cause and staff involved in conflict prospectively. Data were recorded for the same two 12-week periods in 2013 and 2014, in one UK children's teaching hospital. Data were analysed using descriptive statistics and correlation, the findings of which informed the construction of a semistructured interview schedule. Qualitative interviews were conducted with six key informant healthcare professionals to aid data interpretation; interviews were analysed thematically. RESULTS: 136 individual episodes of conflict were reported. The three most common causes were 'communication breakdown', 'disagreements about treatment' and 'unrealistic expectations'. Over 448 h of healthcare professional time was taken up by these conflicts; most often staff nurses, consultants, doctors in training and matrons. The mean severity rating was 4.9 out of 10. Qualitative interviews revealed consensus regarding whether conflicts were ranked as low, medium or high severity, and explanations regarding why neurology recorded the highest number of conflicts in the observed period. CONCLUSIONS: Conflict is prevalent across paediatric specialties, and particularly in neurology, general paediatrics and neonatology. Considerable staff time is taken in managing conflict, indicating a need to focus resources on supporting staff to resolve conflict, notably managing communication breakdown.

Lymphocyte subpopulations in premature infants: an observational study.

BACKGROUND AND OBJECTIVES: The infant's immune system evolves over the first months and years of life. Strong correlation exists between lymphocyte count, lymphocyte subpopulations and gestational age at birth. Associations with antenatal and postnatal steroid treatment, infection and chronic lung disease have also been described. Few published studies report the effect of increasing postnatal age (PNA) and comorbidities on lymphocyte subpopulations in premature infants beyond the first 4 months of life. This study aimed to describe changes in lymphocyte subpopulations in preterm infants up to 13 months PNA. METHODS: Premature infants (23-34 weeks completed gestation) from five centres had lymphocyte subpopulations measured at 2, 5 or 7, 12 and 13 months PNA alongside their vaccine responses in a vaccination trial. RESULTS: 393 blood samples from 151 babies were analysed. There was an increase in absolute numbers of total lymphocytes (median cell count 6.21×109/L at 13 months compared with 4.9×109/L at 2 months PNA) and CD3+, CD4+, CD8+, natural killer and B cells with increasing age. At 2 months PNA, there was a positive correlation between gestation and CD3+ and CD4+ counts (r=0.32 and 0.46, respectively) and proportions (r=0.22 and 0.41, respectively), and CD4+:CD8+ ratios (r=0.57), but a negative correlation with CD8+ proportions (r=-0.32). CONCLUSIONS: This longitudinal study describes the distribution of lymphocyte subpopulations in premature infants and provides reference ranges for the major lymphocyte subsets to help guide clinicians when assessing premature infants for immunodeficiency in the first year of life. TRIAL REGISTRATION NUMBER: EudraCT 2007-007535-23.

Using a simple point-prevalence survey to define appropriate antibiotic prescribing in hospitalised children across the UK.

BACKGROUND: The National Health Service England, Commissioning for Quality and Innovation for Antimicrobial Resistance (CQUIN AMR) aims to reduce the total antibiotic consumption and the use of certain broad-spectrum antibiotics in secondary care. However, robust baseline antibiotic use data are lacking for hospitalised children. In this study, we aim to describe, compare and explain the prescription patterns of antibiotics within and between paediatric units in the UK and to provide a baseline for antibiotic prescribing for future improvement using CQUIN AMR guidance. METHODS: We conducted a cross-sectional study using a point prevalence survey (PPS) in 61 paediatric units across the UK. The standardised study protocol from the Antibiotic Resistance and Prescribing in European Children (ARPEC) project was used. All inpatients under 18 years of age present in the participating hospital on the day of the study were included except neonates. RESULTS: A total of 1247 (40.9%) of 3047 children hospitalised on the day of the PPS were on antibiotics. The proportion of children receiving antibiotics showed a wide variation between both district general and tertiary hospitals, with 36.4% ( 95% CI 33.4% to 39.4%) and 43.0% (95% CI 40.9% to 45.1%) of children prescribed antibiotics, respectively. About a quarter of children on antibiotic therapy received either a medical or surgical prophylaxis with parenteral administration being the main prescribed route for antibiotics (>60% of the prescriptions for both types of hospitals). General paediatrics units were surprisingly high prescribers of critical broad-spectrum antibiotics, that is, carbapenems and piperacillin-tazobactam. CONCLUSIONS: We provide a robust baseline for antibiotic prescribing in hospitalised children in relation to current national stewardship efforts in the UK. Repeated PPS with further linkage to resistance data needs to be part of the antibiotic stewardship strategy to tackle the issue of suboptimal antibiotic use in hospitalised children.

Schedules for Pneumococcal Vaccination of Preterm Infants: An RCT.

BACKGROUND AND OBJECTIVE: Premature infants have a higher risk of invasive pneumococcal disease and are more likely to have lower vaccine responses compared with term infants. Increasingly, immunization schedules are including a reduced, 2-dose, pneumococcal conjugate vaccine priming schedule. Our goal was to assess the immunogenicity of 3 commonly used 13-valent pneumococcal conjugate vaccine (PCV13) priming schedules in premature infants and their response to a 12-month booster dose. METHODS: Premature infants (<35 weeks' gestation) were randomized to receive PCV13 at 2 and 4 months (reduced schedule); 2, 3, and 4 months (accelerated schedule); or 2, 4, and 6 months (extended schedule). All infants received a 12-month PCV13 booster. Serotype-specific pneumococcal immunoglobulin G (IgG) for PCV13 serotypes was measured by using enzyme-linked immunosorbent assay 1 month after the primary and booster vaccinations. RESULTS: A total of 210 infants (median birth gestation, 29(+6) weeks; range, 23(+2)-34(+6) weeks) were included. After the primary vaccination, 75% (95% confidence interval [CI], 62-85), 88% (95% CI, 76-95), and 97% (95% CI, 87-99) of participants had protective antibody concentrations for at least one-half the PCV13 serotypes for the reduced, accelerated, and extended schedules, respectively. After the booster vaccination, participants receiving the extended schedule had significantly lower (P < .05) geometric mean concentrations compared with reduced (for 9 of 13 serotypes) and accelerated (for 4 of 13 serotypes) schedules, but nearly all participations, regardless of schedule or serotype, had seroprotective IgG concentrations. CONCLUSIONS: A reduced priming schedule of PCV13 resulted in higher post-booster IgG concentrations but lower post-primary concentrations. The optimum vaccine schedule for preterm infants will therefore depend on when they are most at risk for invasive pneumococcal disease.
