Safe prescribing, administration and monitoring
Also known as Medication safety in children · Preventing paediatric medication errors · The rights of medication administration · Therapeutic drug monitoring in children · High-alert medicines and dose checking
Fellowship guide to safe prescribing, administration and monitoring of medicines in children: the medication-use process, the paediatric factors that make dosing error-prone (weight-based calculation, developmental pharmacokinetics, off-label use), where errors happen and how to stop them (the rights of administration, independent double-checks, computerised order entry with decision support, unit-based pharmacists, standard concentrations), high-alert medicines, and therapeutic drug monitoring targets for gentamicin, vancomycin and phenytoin, with ANZ, UK, US and Canada guidance.

Red flags
- Writing a weight-based dose without an independent second check, or after estimating the weight instead of weighing the child
- A ten-fold dosing error from a misplaced decimal point, a trailing zero, or a misread unit
- Giving a high-alert medicine (insulin, opioid, concentrated electrolyte, anticoagulant, chemotherapy) without an independent double-check
- Missing a supratherapeutic or subtherapeutic level because a gentamicin, vancomycin or phenytoin level was not taken or not acted on
- Reconciling medicines poorly at admission, transfer or discharge so a medicine is doubled, stopped or omitted
- Using an abbreviation, a look-alike name, or a non-standard concentration on a free-text prescription

Two ideas that get blurred
A medication error
An adverse drug event
Right patient (two identifiers) · Right drug (check the name, not the trade) · Right dose (independently re-calculate by weight) · Right route · Right time and frequency · Right reason and documentation. Add the modern extras an examiner rewards: right formulation, right rate for infusions, and right response by monitoring the effect. [1]
Overview & Definition
A four-year-old on the ward is prescribed gentamicin for a urinary infection. The dose is worked out from her weight, written on a chart, transcribed, drawn up, given over an hour, and followed by a level. Each of those steps is a chance to get it right or to harm her, and a medication error at any one of them — a misplaced decimal, a missed level, a doubled dose after transfer — can outpace the infection itself. Safe prescribing, administration and monitoring is the discipline of running a medicine through that whole chain so that the right child reliably gets the right drug, at the right dose, by the right route, at the right time, with the response checked. [1]
Medication safety draws a clear line between an error and the harm it may cause. A medication error is any preventable event in the medication-use process that may cause or lead to inappropriate use, whether or not the child is injured; an adverse drug event is actual harm from a medicine, which may be preventable, ameliorable, or unavoidable. Most errors are intercepted or cause no harm, yet they mark a system whose next failure may not be benign, which is why safety practice hunts the error even when no child was hurt. [1] [7]
The paediatric difference is the whole reason this topic exists as its own subject. Adults take standard doses; children almost never do. A dose depends on weight or body-surface area, on age-dependent handling of the drug, and often on an evidence base extrapolated from adults and used off-label, so the calculation step that adults skip is the single most error-prone step in children. Layer on the narrow therapeutic windows of neonatal and critical care medicines, and a safe system is not a courtesy but a necessity. [5] [10]
