  • Save nurses time
  • Optimise pain management for patients
  • Increase response time to patients.


An investigation in nursing time management was carried out in the hospital setting; one highlighting an excessive waste of time and energy for nursing staff.

Each hospital or aged-care ward has a dangerous drug (DD) cupboard containing Schedule 8 Drugs – these are usually addictive drugs such as morphine, pethidine and endone. On each shift a registered nurse must carry keys on his/her person at all times. The keys are often handed around to a variety of registered nurses throughout the shift, as the need arises. Staff can only access the DD cupboard in the presence of another Registered Nurse or Endorsed Enrolled Nurse and each drug is counted and signed upon administration to the patient.


The problem that often arises is the nurse carrying the DD keys may not be easy to locate.  Nursing staff must then walk around the ward trying to locate the nurse with the keys (sometimes taking up to 15 minutes) wasting time and the ability to manage a patient’s pain.

Attempted solutions:

Nursing units have tried a variety of solutions to overcome this issue. In some hospitals the nurse with the DD keys carries a phone. Unfortunately this system becomes ineffective with staff forgetting the phone and with the keys changing hands throughout the shift.

Other units have tried using a door bell located near the DD cupboard rang only when the keys are required.  This is also ineffective as staff cannot hear the doorbell when in a patient’s room.


The DDfinder has been developed to overcome such difficulties. The small DDfinder pager is permanently attached to the keys, with the call bell permanently attached to the DD cupboard making it more efficient for nurses to gain access to the DD cupboard.
