Paediatric dosing is a fundamental aspect of child healthcare, involving a precise calculation of medication dosages based on various factors. Among the several methods available for these calculations, the West Nomogram rule stands out. It offers an efficient, accurate way to determine safe drug dosages for children. This guide will introduce you to the West Nomogram rule, discuss its application, and provide an example.

The West Nomogram, also known as the 'Best Guess' method, was developed in 1977 by Dr. J. West, a pioneer in paediatric dosing. This method incorporates a child's body surface area (BSA) and is particularly relevant when dosing drugs with a narrow therapeutic index.
The formula for the West Nomogram rule is given as:
Child's Dose = Adult Dose × (Child's BSA / 1.73 m2)
The West Nomogram rule extends its influence beyond paediatrics into the realms of pharmacology, healthcare policy, and nursing. In pharmacology, the rule is essential in drug development for children. For healthcare policy, it's instrumental in defining guidelines around paediatric medication, and in nursing, it's vital for the accurate and safe administration of medications.
For instance, let's assume the adult dose of a specific drug is 150mg and the BSA of the child is 0.8 m2. Applying the West Nomogram rule:
Child's Dose = 150 × (0.8 / 1.73) = 69.36mg (rounded to 70mg)
The calculated dose is the amount of the drug that should be administered to the child.
Dr. J. West, who developed this approach, made significant contributions to paediatric healthcare. His method for paediatric dosing calculation greatly increased the safety and efficacy of drug administration in children, ensuring they receive the most appropriate and effective dosage of medication.
