Three Missing Morphine Ampoules at Shift Handover
You are the pharmacist in charge of the dispensary at a 180-bed tertiary hospital in Ibadan. At the 7 a.m. shift handover, the night nurse reports that the ICU controlled-drug cupboard contains three fewer ampoules of morphine 10 mg/mL than the balance recorded in the register. The last entry was signed at 10 p.m. by a nurse who has since gone off duty. The cupboard key was kept in the duty nurse's drawer, and the register shows one entry altered with correction fluid. A postoperative patient in ICU is due for morphine in 30 minutes, and the ward has only two ampoules left. The hospital policy requires two signatures for every controlled-drug transaction. The nurse in charge says the discrepancy is probably a documentation error and asks you to 'sort out the register' before the morning ward round. The medical director is not yet on site.
1. What are your immediate priorities, and how would you manage the patient's next dose without falsifying records?

Priority order: patient care first, then securing the evidence.
- Assess the patient's prescription and clinical need. Confirm the morphine order, dose, route, time due, and the patient's pain score and vital signs. The patient must not be left in pain because of an administrative discrepancy.
- Use the remaining two ampoules if the prescribed dose can be safely prepared from them. Two people should check the order, calculate the dose, witness the preparation, and sign the register for the dose actually administered. Record the true balance after use.
- Do not alter, rewrite, or 'correct' the register entry. The correction-fluid entry is part of the evidence. If a new entry is needed, make a factual note that does not destroy the original.
- Secure the cupboard immediately. Count the remaining stock with the nurse in charge and a third witness, record the actual count, lock the cupboard, and restrict access. Consider moving remaining morphine to a secure location and issuing a documented replacement through normal channels if patient care requires it.
- Notify the pharmacy head and hospital management the same morning. Do not wait for the ward round to end.
'Sorting out the register' to match the stock would be a false record and a serious professional and legal breach.
2. Outline the investigation and reporting steps you would take.

Investigation
- Preserve the register, the correction-fluid page, the cupboard log, and any keys or access records. Do not let staff rewrite or replace them.
- Reconstruct the last 24 hours: every morphine order, administration, return, and wastage. Compare the register with the patient's medication chart, the ICU treatment sheet, and any theatre or transfer records.
- Check whether ampoules were transferred to another ward, returned unused, or discarded without documentation. Check sharps bins and waste only with proper safety procedures.
- Interview staff separately and factually: the night nurse, the nurse who signed the 10 p.m. entry, the duty nurse holding the key, and anyone who accessed the cupboard. Avoid accusations at this stage.
- Review access controls, CCTV if available, and whether the key was left in an insecure drawer.
Reporting
- Report the discrepancy in writing to the pharmacy head, the hospital's controlled-drug officer, and management.
- Report the loss to the appropriate regulatory authority as required for controlled drugs; in Nigeria this includes PCN and the NDLEA channels used by the hospital. Keep copies of all correspondence.
- If diversion or theft is suspected, follow the hospital's disciplinary and police-reporting policy after management review.
- Record the outcome and any disciplinary or system action in the incident file.
3. What system changes would you recommend to reduce the chance of a repeat discrepancy?
Read the worked answer
System changes
- Move from a paper register with correction fluid to a tamper-evident register or an electronic controlled-drug system with audit trails, restricted logins, and no ability to delete entries.
- Enforce two-signature reconciliation at every shift change, not only at issuance. The outgoing and incoming nurses should count together in front of the cupboard.
- Keep the cupboard key with a named accountable person, not in an unlocked drawer. Use a key log and a second key held by pharmacy or security.
- Separate the roles of ordering, storing, and administering where staffing allows, and restrict cupboard access to trained staff.
- Require documented returns and witnessed wastage of part-used ampoules.
- Conduct unannounced audits and monthly reconciliation of purchases, stock, and administrations.
- Train staff on the legal status of controlled drugs and on a blame-free but accountable reporting culture. The aim is early detection, not concealment.
- Review staffing at night and the process for obtaining urgent stock so that a nurse is not tempted to bypass documentation during a busy shift.
