Summary

Prescribers need to perform calculations regularly, even with the advent of electronic systems. This is true for every ward, but more so for high-risk specialties such as paediatrics, ICU and anaesthetics. The reader is provided with several rules to manage this, including being clear about units, performing calculations in two directions and avoiding confusion with percentages and ratios.
