With millions upon millions of journal articles being published every year it is impossible to keep up.  Every month we ask some of our friends from PERUKI (Paediatric Emergency Research in UK and Ireland) to point out something that has caught their eye.

Article 1: Are steroids of any use in pre-school wheeze?

Wallace A, Sinclair O, Shepherd M, et alImpact of oral corticosteroids on respiratory outcomes in acute preschool wheeze: a randomised clinical trialArchives of Disease in Childhood 2021;106:339-344

What’s it about? 

This paper looks at a common problem and one where there is huge variation in practice; should we give oral steroids to pre-school children who present to the emergency department with wheeze?

This was a double-blinded, randomised, placebo-controlled trial based in three hospitals in New Zealand. Children were either allocated 3 days of oral prednisolone or a placebo of similar colour, taste and viscosity (yuk!).  The primary outcome was measured by a change in Preschool Respiratory Assessment Measure (PRAM) score at 24 hours, although several interesting secondary outcomes were also measured.  The authors looked at 24–59 month-olds in order to exclude bronchiolitis cases. 3247 children were identified as being eligible with 477 children making it to the intended to treat analysis.

Why does it matter? 

In 2009 Panikar et al found there was no reduction in duration of hospitalization when giving steroids for pre-school wheeze, looking at children from 10 months to 6 years of age. However, in 2018 Foster et al found that giving oral steroids for children aged between 2 and 6 years old reduced their average length of stay from 540 to 370 minutes.

The authors of this paper found no difference in PRAM score at 24 hours between the groups (their primary outcome measure) and also no difference in the number of doses of salbutamol administered, length of stay for those admitted or representation rates within 7 days. A novel finding was that at 24 hours the median PRAM score was 0 for both groups and only one child still had severe disease (PRAM 9-12).  This might be the fact that 218 children were excluded for ‘severe disease’ despite this not being in the exclusion criteria, as well as 175 children excluded for previous life-threatening asthma and 123 excluded for chronic respiratory or cardiac disease.

However, the authors did find that the prednisolone group had less respiratory distress 4 hours after medication administration and reduced requirement for hospital admission, additional corticosteroid or intravenous treatment.

Clinically Relevant Bottom Line:

The results of this study suggest that giving oral steroids for pre-school wheeze is of limited benefit. However it may explain why there is perceived benefit, children clinically respond in the first 4-6 hours even if the overall outcome isn’t altered. It’s not clear from the study how long after arrival steroids were given and this may be an interesting area of further study.

Many centres now give single-dose dexamethasone which concords with the findings of this study in that 3 days of prednisolone may not be necessary given the median PRAM score of 0 at 24 hours. Some clinicians may find the reduced need for intravenous medications or hospital admission sufficient benefit to give a single dose of dexamethasone in the PED and so it is unlikely the debate about which pre-school children should receive steroids has been put to bed.

Article 2: This is just how I cope

Herrick SS, Hallward L, Duncan LR. “This is just how I cope”: An inductive thematic analysis of eating disorder recovery content created and shared on TikTok using #EDrecovery. International Journal of Eating Disorders. 2021 Apr;54(4):516-26.

What’s it about? 

This Canadian study investigated the impact of eating disorder (ED) recovery videos shared on the social media platform TikTok.

The study completed a thematic analysis of the first150 TikTok posts under the hashtag #EDrecovery (Eating Disorder recovery) in June 2020 (454.5 million views as of June 2020 and around 1,500 posts with this hashtag).

Five themes were identified: ED awareness (N=32), Inpatient story time: “ED unit tings” (N=28), Eating in recovery (N=27), Transformations: “how about a weight gain glow up?” (N=27) and Trendy gallows humour: “let’s confuse people who have a good relationship with food” (N=36).

In around 1 in 5 of the posts creators shared different aspects of recovery to encourage a better understanding of recovery and ED’s. Four subthemes were found: recovery victories, reality of recovery, education and sharing positivity within these raising awareness posts.

Although the #EDrecovery videos raised awareness about eating disorder, some videos contain content which blur the line between ED recovery and pro-ED content and may be harmful to some TikTok users.

Why does it matter? 

Social media channels such as TikTok has a large impact on its user base, the majority of which are children and teenagers. TikTok formed in 2017 is one of the fastest growing mobile apps- with over 2 billion downloads (as of January 2020) and a whopping estimated 80 BILLION active users, the majority being children and young adults.

TikTok can be used to spread ED awareness and build a supportive community for ED recovery users. It is important to explore whether TikTok can be used as a tool to assist in ED recovery.

Clinically Relevant Bottom Line:

A fine line exists between ED recovery and pro-ED content. Some users find #EDrecovery videos helpful, while others may misinterpret the videos as triggering their ED behaviour.

Article 3: Do rapid diagnostic methods improve antibiotic prescribing in bacteraemia?

Faugno, AK., Laidman, AY., Perez Martinez, JD., Campbell, AJ., & Blyth, CC. (2021). Do rapid diagnostic methods improve antibiotic prescribing in paediatric bacteraemia? J Paediatr Child Health, 57(4), 574–580. https://doi.org/10.1111/jpc.15272

What’s it all about?

Rapid diagnostic methods are being developed to identify causative pathogens earlier to optimise early antibiotic therapy for patients with bacteraemia. The authors performed a retrospective study of 255 bacteraemia cases at a tertiary referral hospital in Western Australia. They compared patient outcomes in cohorts receiving antibiotics before and after the implementation of two rapid diagnostic tests: matrix-assisted laser desorption ionisation time-of-flight (MALDI-TOF) and GeneXpert Xpert MRSA/SA.

The median time taken to administer optimal therapy was not significantly different between those undergoing rapid diagnostic testing and those who did not (39.1 vs 44.4hrs, p= 0.66). Similarly, there was no significant difference in hospital length of stay (7 vs 9 days), number of ICU admissions (20 vs 15) or all-cause mortality (1.6 vs 1.6%).

Why does it matter?

It is well-established that timely administration of empirical antibiotic therapy in cases of sepsis can reduce mortality and morbidity. In fact, one-third of paediatric deaths within intensive care units are associated with sepsis or septic shock. What’s more, the prolonged use of broad-spectrum antibiotics and delay in targeting optimal therapy can potentiate antibiotic resistance.

Adult studies have already shown that timely identification of pathogens can improve appropriate antibiotic therapy but there is little known about its effect in paediatric populations who present with a difference clinical and microbiological profile.

The Bottom Line:

The lack of significant difference in this clinical outcome data suggests that there is no beneficial impact of implementing rapid diagnostic testing in paediatric populations with bacteraemia. The authors suggested possible reasons for this, such as the lack of explanations or training in interpreting rapid diagnostic test results for treating doctors, and therefore the need for a real-time programme to support clinical decision making. 

However, it would be interesting to compare this data to other paediatric hospitals through a multi-centre study, given that other regions may have higher rates of antimicrobial resistance and candidaemia which can alter the effectiveness of empiric antibiotic therapy. Moreover, changes to hospital guidelines for empirical therapy may be better captured through prospective studies in the future.

Article 4: What’s the time, Mr Wolf?

Stellman, R., Redfern, A., Lahri, S., Esterhuizen, T., Cheema, B. (2021) How much time do doctors spend providing care to each child in the ED? A time and motion study. Emergency Medicine Journal, Published Online First: 15 April 2021. doi: 10.1136/emermed-2019-208903

What’s it about?

The authors conducted a cross-sectional observational study over a 5-week period in two EDs – a tertiary centre and a large district hospital, both with separate paediatric ED areas – in the Western Cape of Africa. The “time and motion” methodology was used, where a single trained, independent observer was placed in the ED and observed and timed Doctors’ interaction with patients that met inclusive criteria. Criteria included age (0-13 years), unplanned presentation (not referred  by another source) and had an initial assessment by a qualified medical officer employed by that site. The patient triage category, as per the South African Triage Scale, was also recorded. Primary objective: to measure the total time taken by doctors to assess and manage each of a series of paediatric patients. Secondary objective: whether acuity of patient—as estimated by triage category affected the average time taken, and to compare these averages to the estimated benchmarks used to calculate hospital staffing allocations in the region.

A total of 100 patients were included and the median DTPP (doctor time per patient) for each triage category was as follows:

• Green (routine; see within 4 hours): 31 minutes (Target set for staffing calculations are: 15 minutes for green)
• Yellow (urgent; see within 1 hour) 39 minutes (Target 40mins/ patient)
• Orange (very urgent; see within 10 minutes) 48 minutes (Target 50min/patient)
• Red (emergency; see immediately) 96 minutes (Target 50min/ patient)

These time frames were compared with the local hospital benchmarks (developed to guide assigning ED staffing) and found that the median timing for patients triaged as green and red were significantly higher (p=0.001 and p=0.002, respectively). 

Why does it matter?

Time often seems warped inside the Emergency Department (ED) – some shifts fly by while others seem to drag on. Sometimes, you see a new patient every 30 minutes, and other times, you spend 3 hours with just one patient! Whilst most ED have audits to monitor Key Performance Indicators (KPI) looking at waiting times, time to treatment, time to admission / time to discharge etc few studies actually look at the (DTPP), which is the time spent assessing and managing a patient. This value depends on a large number of medical and psychosocial variables but if it can be accurately measured, it could be used to determine the right staffing required in a department.

The bottom line

Even with the limitations of this study (small sample size, only a single observer collecting data for a short period of observation per day), the DTPP was found to be significantly higher than the local expected time frame for the highest and lowest triage categories. This study could be repeated at your local ED (with the limitations addressed) and the information could be useful in determining whether your ED is adequately staffed, which would in turn improve a variety of KPIs.

Article 5: Is the use of excessive non-resuscitation fluid associated with worse outcomes?

Barhight MF, Nelson D, et al.Non-resuscitation fluid in excess of hydration requirements is associated with higher mortality in critically ill children [published online ahead of print, 2021 Mar 17]. Pediatric Research. 2021;1-6.

What’s it about?

This study looks at whether giving excessive non-resuscitation fluid to critically unwell children is associated with a worse clinical outcome.

The authors conducted an observational study in PICUs of two large American hospitals between 2010 and 2018. They reviewed 14,483 patients and calculated their daily fluid balance for the first 3 days of their stay. This included all fluid given that wasn’t prescribed as a ‘bolus’. They then used the cumulative fluid balance at the end of day 3 to work out a percentage fluid overload (FO) which they stratified into <10%, 10-20% and >20%. The primary outcome was in-hospital mortality and the secondary outcome was ventilator-free days at 28 days.

For each FO category, the volume of fluid that was given in excess of the estimated requirement (using the Holliday-Seger method) was calculated. This demonstrated that excess non-resuscitation fluid was given in just over 1 in 2 of the patients and that maintenance fluid and nutrition were the largest contributors to fluid input. The number of patients receiving excess fluid increased with each FO category and equated to an excess of 164ml/kg in the >20% group.

Analysis was performed for each FO strata to look for an association between % FO and mortality, adjusting for confounders such as age and illness severity. This demonstrated an increase in adjusted odds of death when compared to the <10% group of 1.8 times in the 10-20% group and 2.6 times in the >20% group.

The authors also found that for every 10ml/kg of excess fluid given, there was 1.01 times higher odds of death. There was also a 1% decrease in likelihood of having a ventilator free day.

As this is an observational study, it can only demonstrate associations and not causality.

Why does it matter?

In the adult population studies have shown that almost 60% of the fluid administered to patients was in the form of maintenance fluids and “fluid creep” (the combined volume used from medications, electrolytes, and continuous infusions used to keep access lines open).

Even though this study relates to critically unwell children, maintenance fluids are something we prescribe routinely within paediatrics, and this study highlights the need for a carefully considered approach to their use in all children, with frequent readjustment according to fluid balance so as not to cause harm.

Further studies are required to examine whether our current prescribing practices should be modified, but nevertheless, this study should make us think more carefully about how much fluid we are giving to our patients.

Clinically Relevant Bottom Line:

 This study shows that non-resuscitation fluids are frequently given to patients in excess of their hydration requirements and could represent potential iatrogenic harm.

With millions upon millions of journal articles being published every year it is impossible to keep up.  Every month we ask some of our friends from PERUKI (Paediatric Emergency Research in UK and Ireland) to point out something that has caught their eye.

Article 1: An update on PIMS-TS/MIST-C

Flood J, Shingleton J, Bennett E, Walker B, Amin-Chowdhury Z, Oligbu G, Avis J, Lynn RM, Davis P, Bharucha T, Pain CE. Paediatric multisystem inflammatory syndrome temporally associated with SARS-CoV-2 (PIMS-TS): Prospective, national surveillance, United Kingdom and Ireland, 2020. The Lancet Regional Health-Europe. 2021 Apr 1;3:100075.

What’s it about? 

During the first breakout of PIMS-TS, Public Health England (PHE) and the British paediatric surveillance unit (BPSU) requested reports of PIMS-TS, Toxic shock syndrome (TSS) and Kawasaki Disease (KD) to be submitted for prospective national surveillance. This study looks at patients under the age of 16 who presented with symptoms between 1^st March and 15^th June 2020. The symptoms for the diagnosis of PIMS-TS was set out as per RCPCH guidance (fever >38, CRP>100, no infection proven and evidence of one at least system dysfunction) along with strict criteria for KD and TSS. From these reports, patients were excluded if they did not meet any PIMS-TS resulting in 268 cases of PIMS-TS meeting diagnostic criteria.

Why does it matter? 

Children have made up a small proportion of direct clinical burden due to COVID-19. However, cases all over the world began to appear of PIMS-TS associated with SARS-CoV-2 infection and more information was needed to be able to map this disease process and use clinical data to explain clinical characteristics of PIMS-TS and the epidemiology between these overlapping clinical conditions.

The results of the study showed the median age to be 8 years with PIMS TS/KD subgroup younger (5 years) and PIMS TS/TSS older (8 years) than PIMS TS only cases (7years). 60% of the population were male and patients from the BAME community seem to be disproportionately affected, especially within London.

Patients who exhibited PIMS-TS with features of TSS as well seemed to fair worse with a larger number of interventions, longer hospital stay and severity of illness. 35 cases were felt to be clinically in keeping with PIMS-TS despite not meeting the CRP criteria. Parental occupation was reported in just under half of the cases and more than 2 out of 3 were reported as healthcare workers. Just over 1 in 3 of the children had evidence of current or previous SARS-CoV-2 infection.

Clinically Relevant Bottom Line:

Presentations of PIMS-TS are strongly linked with SARS-CoV-2 infection, and those with features similar to toxic shock syndrome tend to be more unwell. Children in London, and in the BAME population, seem to be disproportionately represented, with the most having severe presentations. The epidemiological links are similar to that of other countries.

Article 2: Screening adolescents for the risk of suicide attempts

Pediatric Emergency Care Applied Research Network (PECARN) King CA, Brent D, Grupp-Phelan J, et al., (2021) Prospective Development and Validation of the Computerized Adaptive Screen for Suicidal Youth. JAMA Psychiatry. 2021 Feb 3:e204576

What’s it about? 

A prospective 2-part study with data collection being undertaken at different ED’s in the United States, which are part of the PECARN network. Introduction of computerised adaptive testing (CAT) which put simply is a tool that takes individuals responses to questions and determines their standing on the measured trait e.g., risk of suicide attempt. This offers the possibility of a more individualised, accurate screening tool.

Two studies ran independently:

Study 1(2015-2016): used CAT to develop a screening tool (computerised adaptive screen for suicidal youth CASSY) that targets items to the individuals personal risk profiles to provide a continuous risk score for the likelihood of suicide attempt (SA) within 3 months.

Study 2 (2017-2018): Prospectively validated CASSY.

In Study 1, adolescents aged 12 – 17 years who presented to ED were offered to complete the Ask Suicide Questions (ASQ) and Columbia Suicide Severity Rating Scale (C-CSSR). Depending on these responses the participants were stratified into low medium/ high risk for suicide attempt. Then a random selection of these were assigned to follow up which was done by interviewers who were blinded to the baseline data were responsible for the 3-month telephone follow up which assessed the number of suicide attempts made by the patient during this time.

CASSY was then developed using questions from these screening tools (questions which were identified to have high suicide attempt predictive value) and was cross validated in Study 1, before it’s use in Study 2. Subsequently, adolescents aged 12 – 17 years who presented to ED were offered to complete CASSY.

The authors have used a multivariate logistic regression model to predict suicide attempt during the 3 months follow up. Based on this, the Receiver Operating Characteristic (ROC) curve demonstrates a sensitivity of 82.4% for predicting suicide attempts using the CASSY score, at a specificity of 80% with an area under the curve (AUC) of 0.87 [95% CI, 0.85-0.89].

For a reminder on these type of stats take a look at this DFTB post.

Some important exclusions in this study population were being a ward of the state (e.g. adolescent in foster care) and non-English speaking participants which from previous studies are shown to be important risk factors for altered mental health.

Why does it matter? 

Data from Australia (and around the world) show that our adolescent population are suffering from increasing levels of mental health issues such as anxiety and depression. With those illnesses often comes suicidal ideation, and when these patients reach crisis point, they present to our emergency departments (ED). One of the biggest challenges to all suicidal risk screening is the accurate identification of young people at risk in a setting that efficiency is required. Existing screening tools such as (ASQ) have shown moderate sensitivity to predicting suicide risk, meaning some individuals at risk were not identified.

Clinically Relevant Bottom Line:

This study shows the CASSY tool has a good sensitivity (ability to pick up) those at risk of suicide attempt. Early and accurate recognition of mental health illnesses and suicidal ideation in primary health care settings and emergency departments is an essential first step in managing these issues.

Article 3: The use of minimally invasive surfactant therapy

Roberts CT, Halibullah I, Bhatia R, Green EA, Kamlin CO, Davis PG, Manley BJ. Outcomes after Introduction of Minimally Invasive Surfactant Therapy in Two Australian Tertiary Neonatal Units. The Journal of Pediatrics. 2021 Feb 1;229:141-6.

What’s it all about?

This 18-month prospective audit collected data on patient demographics and clinical outcomes following the introduction of minimally invasive surfactant therapy (MIST) in two neonatal intensive care units (NICUs) in Australia. Infants were eligible for MIST if they received CPAP support with clinical or radiological diagnosis of respiratory distress syndrome (RDS), and were excluded if they had major congenital anomalies, circulatory compromise, recent apnoeas or a diagnosis other than RDS.

Why does it matter?

MIST is a less invasive method of administering exogenous surfactant for the treatment of RDS in premature infants compared to previous surfactant administration by endotracheal tube. Previous meta analysis highlighted that MIST is associated with reduced need for mechanical ventilation, and adverse events such as bronchopulmonary dysplasia and death compared to endotracheal intubation. However, it is difficult to make clear conclusions about the efficacy of MIST versus endotracheal tubing for surfactant administration, as a range of other factors can affect success rate. These include gestational age, surfactant dose and timing of procedure (as prophylactic after birth versus an early rescue approach within the first 24 hours of life. As MIST and endotracheal intubation require laryngoscopy, the authors stress the continued need to adequately train junior staff and suggest the use of routine video laryngoscopy regularly to allow for second operator confirmation and potentially increased rates of success.

135 MIST procedures were performed. The median gestation was 30 weeks, and median birth weight being 1439 grams. All infants received supplementary oxygen before MIST. The most common adverse event was peripheral oxygen desaturation to <80% which occurred in 3 out of 4 of MIST procedures. Other events included bradycardia <100 beats per minute (13 out of 100) and the need for positive pressure ventilation (1 in 10). Positively, over 2/3rds of infants treated with MIST did not require further intubation and mechanical ventilation and senior clinicians had higher rates of procedural success. Surfactant administration was successful in all but one MIST procedure due to patient apnoea requiring intubation.

The Bottom Line:

The authors determined that MIST can be successfully adopted into clinical practice in such settings where staff have limited prior experience. Rates of adverse events, mentioned above, were comparable to results from previous randomized trials. Over 2/3^rd of infants in this study with MIST did not require further intubation and ventilation.

Article 4: Can we perform phototherapy at home?

Pettersson M, Eriksson M, Albinsson E, Ohlin A. Home phototherapy for hyperbilirubinemia in term neonates—an unblinded multicentre randomized controlled trial. European Journal of Pediatrics. 2021 Jan 19:1-8.

What’s it about?

Within the first week of life, 60% of term babies and 80% of pre-term babies will have some degree of jaundice. This study looked at well term babies and if delivering phototherapy at home, with daily hospital reviews, would be an acceptable alternative to inpatient phototherapy.

This was an unblinded, randomised control trial of 147 jaundiced neonates across 6 hospitals in Sweden. To be included babies had to be well, >48 hours old, have a gestational age >36+0 and have a raised serum bilirubin (SBR). Parents also had to be capable to perform phototherapy at home and agree to return daily for review and blood tests. Babies were excluded if they had a high bilirubin result (>400µumol/L), weight loss of >10% of birth weight, any ongoing infection or illness, or if there was blood group incompatibility.

Babies were randomly selected to receive home phototherapy (78) vs hospital phototherapy (69). Babies in both groups were reviewed daily in the hospital, and a daily SBR and weight. Home treatment was done by Bilisoft (Bilibed) that was provided with eye protection and clear instructions. This study could not find any statistically significant differences that suggested that either therapy was superior to the other. Only 3 in 78 babies of the home phototherapy neonate were converted to hospital treatment. No one across either group had SBR’s high enough to require IVIG or blood exchange. There was no statistically significant difference regarding the duration of phototherapy, time until discharge, amount of blood tests, weight loss or adverse events.

Why does it matter?

Jaundice is one of the most common reasons for prolonged postnatal hospitalisation and readmissions in the postnatal period. Hospital management of jaundice can negatively impact bonding and attachment, it can be inconvenient for families and is associated with a significant cost to the healthcare system.

The bottom line

This study shows that with daily reviews and monitoring, home phototherapy could be an effective and safe alternative to hospital phototherapy for otherwise healthy, term, neonates. When determining appropriateness for home phototherapy bilirubin levels, geographic location and ability to commute, parental anxiety and the capability of parents/carers must all be considered.

Article 5: How is procedural sedation performed in Europe?

What’s it about?

This cross-sectional study of european paediatric procedural sedation and analgesia (PSA) was endorsed by the Research in European Paediatric Emergency Medicine (REPEM) network, with data collection between November 2019 and March 2020. 

The study aimed to describe PSA practice across europe, perform a needs assessment-like analysis and also identify barriers to PSA implementation.

Online questionnaires were distributed to a target number of either 10 or 5 emergency departments within each country (depending on their population size), via country specific lead research coordinators. The survey included a clinical case scenario with subsequent questions covering 8 key themes. These ranged from the management of a patient requiring PSA, protocols and safety and barriers limiting PSA implementation. The questionnaire was revised several times following input from each country lead, accounting for variations in relevance, language, and grammar between each country, until a consensus was achieved containing 30 questions. Questionnaires were completed by a senior clinician at each site with 171 hospitals contributing data from 19 countries. The UK and Ireland were not included due to a similar project running in these locations simultaneously.

Midazolam (100%) and Ketamine (91%) were the most available PSA medications, followed by propofol (67%), nitrous oxide (56%) and intranasal fentanyl (47%). 8 in 10 of sites reported sedation being performed by general paediatricians. However just over 1 in 3 of sites stated all staff performing PSA were paediatric advanced life support certified and only 1 in 2 required PSA specific course completion. Safety and monitoring guidelines for PSA were present in most  sites (7out of 10) and 1 in 2 had pre-procedural checklists in place, with these sites most likely to perform IV sedation. Capnography was present in just under half of the sites.

Barriers to PSA implementations included lack of physical space (1 in 2 of sites) and shortages of both nurses and clinicians (both more than 2/3rds of sites). Interestingly half of the sites reported nurse-led triage protocols in use for paracetamol and ibuprofen administration, with these sites experiencing the highest number of patient visits per year.

Why does it matter?

PSA is used widely across europe, however there is a large variation in the standard medications and safety measures in use.

Clinically Relevant Bottom Line:

 This study highlights the need for sharing of best-practice amongst sites with the potential for future trials to determine optimal staff training, medication use, procedural checklists and guidelines, nurse-led triage and staff and physical space allocation for PSA. The network generated as a consequence of this study could be used to facilitate such work in the future.
