The 2nd Bubble Wrap


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 the world of paediatrics to point out something that has caught their eye.

Article 1 – In ED Practice: How can we best provide adequate safety netting?

Curran JA, Murphy A, Burns E, Plint A, Taljaard M, MacPhee S, Fitzpatrick E, Bishop A, Chorney J, Bourque M. Essential Content for Discharge Instructions in Pediatric Emergency Care: A Delphi Study. Pediatric Emergency Care. 2016 Dec 20.

What’s it about? The majority of children who present to urgent and emergency paediatric care will go home. Discharge safety netting advice i.e. what to expect and what to look out for is so commonly given it is incredible in the 21st Century we still don’t know what the ideal advice looks and sounds like. Curran et al. attempt to help answer this question by conducting a Delphi approach to determine the key content of discharge advice in 6 common illness presentations.

Why does it matter? Delphi studies are an easy concept but often difficult to deliver. Traditionally they should use a number of experts who make choices on questions over a number of rounds. A facilitator has a key role in collating responses so for subsequent rounds the experts can make more informed decisions about the questions they are answering. The term ‘modified’ Delphi has become increasingly used to avoid the hard work of manually summating the feedback by reducing the number of rounds and just presenting aggregated scores or responses in an electronic format.

In this study experts were doctors and nurses of at least 8 years experience who were selected by invitation from the Emergency Departments of the Paediatric Emergency Research Canada group. 4 rounds of survey were used with more than 75% of the original 49 participants completing all the rounds. The initial round listed all possible content items (anything relevant to tell the parents at discharge) obtained via a literature search from a previously published systematic review. The second round only included items that 70% of the experts scored a 4/5 or 5/5 in relation to importance. The third round retained items that scored 80% (experts were shown their own ratings against the mean ratings at this stage). Content Items were then listed in order of preference and finally the top 5 items chosen by each expert were collated.

Some of the findings were not unsurprising. For Diarrhoea and Vomiting – colour of vomiting, intensity of abdominal pain and being very drowsy all made the final cut. Key admission criteria for bronchiolitis (i.e. drowsiness, very reduced feeding) were essentially the suggested return advice given to parents. For fever, advice was more about emphasising features that are normal (fever itself causes no harm, symptoms are more important than the fever itself). Abdominal pain used red flag symptoms such a blood in the stool and asthma advice highlighted the use of plans and appropriate use of spacers. Advice for abdominal pain had 100% consensus for all the items, for asthma a range between 54% and 91%. However for the final condition Head Injury the highest agreement was 64.9% (return to the ED if the headache isn’t helped by analgesia). The authors were unsure as the cause of this but wondered whether different interpretations of language were the cause. It could be argued that perhaps a independent moderator to collate responses during the rounds, as originally intended by Delphi methodology, may have solved this issue. Alternative this study has identified an inherent weakness in our joint practice. We may think we are saying and doing similar things when it comes to discharge advice for head injury (and asthma) but perhaps we aren’t. The study needs to be repeated in different countries, and it would be useful to extrapolate some of this work with the parent and care giver work which already exists, but provides some powerful food for thought. Is it good enough just to write ‘safety net advice given’ in the notes?

Article 2 – Rethinking an old practice: The problem with bronchiolitis guidelines

Plint AC, Taljaard M, McGahern C, Scott SD, Grimshaw JM, Klassen TP, Johnson DW. Management of Bronchiolitis in Community Hospitals in Ontario: a Multicentre Cohort Study. CJEM. 2016 Feb:1-0.

What’s it about? Plint et al. looked at historical data to see how bronchiolitis was managed in 28 community hospitals in Ontario, Canada. Given that it is such a high prevalence condition it is important that emergency physicians, whether they have received specific sub-speciality training or not, can manage the condition to the best of their ability.

Why does it matter? Whilst there are some ongoing controversies regarding management of this common disease there appeared to be some discrepancies in areas for which the evidence is pretty solid. Plint found that 80% of children received bronchodilators in the ED, 31% received a dose of steroids and 5% received antibiotics for this viral condition. She also found that over half of the children had a chest x-ray. The SGEM team, lead by Ken Milne, examine some of the issues involved in this excellent podcast. We also cover some of the possible reasons for this failure of knowledge translation here.

Article 3 – Just In: Does design matter when it comes to neonatal resuscitation algorithms?

What’s it about? Everyone should know that I’m a big fan of style, with substance.  This Australian group of researchers used a validated assessment tool to examine a number of neonatal resuscitation flowcharts.  By looking at the physical characteristics of the algorithms (such as font size, use of contrast and colour), the structure of the content and the actual layout they were able to assess how affective the algorithms might be as a memory aid.

Why does it matter? Just like the ‘Can’t Intubate, Can’t Intubate’ scenario, neonatal resuscitation is a High Acuity, Low Occurrence (HALO) task.  Unlike CICO,  it is something that most of us are likely to be involved in on a semi-regular basis.  Resuscitation is a team sport however and it will not go well if the whole team is not using the same shared mental model. There are number of algorithms in popular use – ILCOR, ANZCOR, AHA/AAP, ERC and RCSA – and it’s interesting to see that the ILCOR iteration scores highest on using the CMAT tool, given that the ANZCOR one looks nicer.

Article 4 – Managing Medicines: Gentamicin Pharmacokinetics and Monitoring in Pedatric Patients with Febrile Neutropenia

Bialkowski S1, Staatz CE, Clark J, Lawson R, Hennig S.Gentamicin Pharmacokinetics and Monitoring in Pediatric Patients with Febrile Neutropenia. Ther Drug Monit. 2016 Dec;38(6):693-698.

What’s it about? The authors describe gentamicin pharmacokinetics in a population of 69 children with febrile neutropaenia. For a total of 121 doses, the gentamicin AUC & Cmax was assessed to identify if current recommended dosing was achieving pre-defined targets. This is important given the risks of ototoxicity and neurotoxicity with higher peaks & concentrations respectively, compared to the need for achieving clinical efficacy with an adequate dosage.

This is primary literature pure and simple; it’s great to see raw data to underpin (and potentially change) dosing guidelines that at times can appear murky and opaque. The subsequent challenge is that the paper is quite meaty and mathematically dense; clinicians who aren’t up to speed with their pharmacokinetics might be challenged to wade through the data. (For a reminder about these values and what they mean, I read the paper in concert with this diagram and my copy of Don Birkett’s Pharmacokinetics Made Easy.)

Why does it matter? I made three main inferences from the paper; first and foremost, that initial doses of gentamicin are frequently leading to Cmax & AUC values that are lower than ideal. Specifically, that patients may require a higher initial dose of gentamicin on presentation to the Emergency Department than currently recommended. Secondly, that with repeated doses in the same patient, these tend to be corrected – that is, that the Therapeutic Drug Monitoring works. Thirdly, that although in patients with proven Gram negative bacteraemia, levels were more likely to be in range, this was more likely due to dose adjustments with repeated doses, rather than altered pharmacokinetics secondary to sepsis.

Article 5 – Practical Paediatrics: How long a course of antibiotics do children with acute otitis media need?

Hoberman A, Paradise JL, Rockette HE, et al. Shortened antimicrobial treatment for acute otitis media in young children. N Engl J Med 2016;375:2446-2456

What’s it about? I’d be remiss if I didn’t include this paper in the list of what to read this month. The authors compared a 5 day course of co-amoxiclav (plus placebo) against a 10 day course in children under 24 months of age with acute otitis media.

Why does it matter? Most cases of AOM get better on their own with minimal intervention so why should we prescribe a 10 day course of antibiotics in order to reduce (possibly) otalgia in this patient group.  You can read more about my take on the paper here or read Rory Spiegel’s take here.
