NICU Practice document: prescribing and administering of drugs.

Authors: Risk Management Team

Introduction
The purpose of this document is to clarify issues around
drug prescribing and administration and thereby enhance
practice. It has been put together as a learning package for
both medical and nursing staff in Neonatal Services.
It has been compiled in response to prescribing and
administrative incidents reported via the risk reporting
system. Examples used are taken from actual incidents that
have occurred within the service, however examples have
been modified to maintain confidentiality.
The document recognizes a need for back up revision
following medical and nursing induction. It aims to assess
your knowledge and competence regarding drug prescribing
and administration and to clarify areas needing further
education.
All staff will be given the document following their induction.
It will need to be completed and returned within two weeks
for marking. Please hand it to Ruby Lopez (Neonatal Nurse)
for marking. Medical staff will be expected to take it to their
first Consultant appraisal for discussion.
We hope you find this a useful tool.
