It's not the sums, it's the checks

23rd April 2004 at 01:00
I am a mathematics graduate who has spent 35 years teaching sums, among other things. While calculating my wife's tax return the other day I made a mistake and put a decimal point in the wrong place. It is a good job I am not a nurse whose miscalculations are costing lives (TES, April 9).

Fortunately, the answer made no sense in the context of the problem and so I looked over the calculation and found my error. I understand that one of the first things pharmacists are trained to do is to double-check everything, in fact if one observes them dispensing at the chemists it is an automatic action.

Human beings will make mistakes in arithmetic, particularly in a busy, distracting environment.

The question which must be asked as a consequence of the patient drug safety survey must be "how can nurses be trained to evaluate and check all drug doses and how can they be found the time to do this?" and not "what is wrong with maths teaching?"
