The HSE has published guidance  in drawing up an approved list of abbreviations. This is included in a document Code of Practice for Healthcare Records Management document.

Internationally there is much guidance on the use of abbreviations within healthcare settings. The Institute for Safe Medication Practices (ISMP) compiled a list of more than 60 commonly used abbreviations, symbols, and dose designations that have been implicated in medication errors. The Joint Commission on Accreditation of Healthcare Organisations (JCAHO) is another useful resource.

ICAHO has conducted research finding the use of abbreviations in health care may be efficient, however this may be at the expense of patient safety by contributing to medication errors. In addition to publishing a list of approved abbreviations the JCAHO has published lists of approved and prohibited abbreviations.
