Learning outcomes

After this session, you will be able to:•explain what Tall Man lettering is

•identify situations where Tall Man lettering can be used to reduce risk of wrong medicine error

•describe the evidence level for Tall Man lettering as an error-reduction technique.

BackgroundMedicine name errors, particularly with regard to medicines with ‘look-alike, sound-alike’ names, are common and harm can occur.

Page 4: Tall Man lettering

What is Tall Man lettering?• It is an error-prevention strategy used as part of a multi-

faceted approach to reduce the risk of look-alike and sound-alike medicine name confusion and errors.

• It is a typographic technique that uses selective capitalisation to help make similar-looking medicine names easier to differentiate.

• Its purpose is to help select or supply the right medicine.

Page 5: Tall Man lettering

How does it work?Tall Man lettering combines lower- and upper-case letters to highlight the differences between look-alike and sound-alike medicine names, like fluOXETine and fluVOXAMine, making them easier for the eye to distinguish.

Evidence• Evaluation shows considerable variation in the

effectiveness of Tall Man lettering1-15. • Small amount of literature available shows that, at a

minimum, Tall Man lettering should alert clinicians’ to medicines that are at risk of name confusion and possible medication error without increasing the risk of errors.1, 9-14

• Inconclusive data on whether technique is effective in preventing medicine selection errors.15

• Mid Tall Man lettering format advocated as being the most effective and easily applied variant.2,11

Why are we doing this?

• The Commission has received numerous enquires about Tall Man lettering standards, endorsement and application techniques from clinicians and software vendors.

• A New Zealand list would prevent proliferations of local Tall Man lists and inconsistent technique application.

What could Tall Man lettering be used on?

• electronic drop-down medicine lists

• automated dispensing cabinet screens

• SMART pumps

• computer-generated pharmacy labels

• medicine shelf labels

• pre-printed order sheets

Final messages

• Train staff on what Tall Man lettering is and how it works before it is introduced.

• Familiarise staff to existing look-alike/sound-alike name pairs to improve risk awareness.

• Don’t overuse Tall Man lettering as this is likely to reduce the error-reduction effect.

• Don’t use different styles of Tall Man lettering as this will cause confusion.
