What’s different about paediatric
prescribing

What’s different about paediatric prescribing
Children are just small adults
NOT!

Vary in their developmental stages◦Pre-term, neonates, infants, children, adolescents
Dynamic anatomy and physiology◦ Including significant changes in weight and surface
area Differ in ability to metabolise drugs◦Cytochrome p450 enzymes not well developed in
premature neonates
Key differences

More dose calculations are required◦Doses vary depending on age and weight
Doses also vary by indications◦Wide range of correct doses depending on indication
Medicines more commonly used outside licence with lack of clear dosage guidance
Impact of differences in prescribing

System must have near perfect identity management
Patient Identification

Many hospitals have mixed adult and paediatric populations
Not just paediatricians who prescribe Particular issues with adult surgeons who also
operate on children Separate Paediatric formulary or order sets
Prescribing in a mixed setting

What is the best way to build paediatric drug catalogue and order sentences
Options◦ Integrate with adult orders◦Separate paediatric orders
Setting up Paediatric Prescribing

Age and weight based calculations Dose calculators often crude and work out
doses that are too precise Need to take indication into account
Can create order sentences based on age and or weight or post-menstrual age for premature babies
Prescribing the correct dose

Not just prescribing systems but also medicines administration
Prescribing doses that can be administered safely◦By nurses and caregivers
Prescribe drugs to be administered at child friendly times
Orders to include correct diluents and administration instructions
EPMA not just EP
![Page 16: What’s different about paediatric prescribing. Vary in their developmental stages ◦ Pre-term, neonates, infants, children, adolescents Dynamic anatomy](https://reader035.vdocuments.us/reader035/viewer/2022062320/56649ced5503460f949b9915/html5/thumbnails/16.jpg)
Most systems do not generate easily administered doses
Rounding tolerances depend on age of child and indication
This is an area of significant interest now◦STEPStool project in US trying to come up with
rounding parameters for certain medications
Dose rounding

Knowledge of child’s precise weight essential◦Validate weights outside normal ranges for age
Caution due to variation in development◦ Interaction management may be different in premature
neonates vs adolescents Develop indication specific order sets to make
relevant orders more accessible to clinicians Round doses to an amount that can be
administered
