A GP practice manager notices that the record for monitoring the medication in the fridge has not been kept up-to-date recently.
They raise this with the practice nurse at their regular monthly meeting.
The practice nurse checks the records, and identifies the gaps as relating to their own recent holidays. They double check that the current stock of medication is all in date. They also update the instructions for locum nurses, to ensure that they include the need to check the fridge and where to record the check. The practice manager is satisfied that the problem has been resolved through business as usual processes.
