Documentation Gap in a Compounded Sterile Preparation Record
A pharmacy technician compounds a batch of 10 bags of vancomycin 1 g in 250 mL of 0.9% sodium chloride. The master formulation record lists the ingredients, quantities, and beyond-use date. The technician's batch record shows the date, the drug lot, the diluent lot, and the preparer's initials, but the verifying pharmacist's signature is missing on 3 of the 10 bags. The technician also did not record the time of preparation. The bags are stored in a refrigerator at 4°C. The pharmacist is about to release the batch to the floor. A nurse calls asking whether the bags can be released because the floor is short on vancomycin.
1. Can the 3 bags without pharmacist verification be released? What documentation must be completed first?
Read the worked answer
No - the 3 unverified bags cannot be released.
Reasoning:
- Pharmacist verification is a required element of the compounded sterile preparation record. Without it, the preparation has not been confirmed for identity, strength, sterility, and quality.
- Missing preparation time is also a required record element; without it, the beyond-use date cannot be reliably calculated.
Required documentation before release:
- Pharmacist's signature or electronic verification for each bag.
- Time of preparation.
- Confirmation of the assigned BUD based on storage at 4°C.
- Any deviation notes.
If the pharmacist cannot verify after the fact with confidence, the bags should be discarded and remade.
2. What regulatory and quality-assurance principles apply to this documentation gap, and what corrective action should the pharmacy take?
Read the worked answer
Principles:
- USP <797> requires that the compounding record include the name and amount of ingredients, the source, the date and time of preparation, the identity of the preparer and verifier, and the assigned BUD.
- Traceability: Lot numbers and times allow recall and investigation if a problem occurs.
- Accountability: The pharmacist's signature confirms the final check.
Corrective actions:
- Conduct a root-cause analysis of why signatures and times were omitted (e.g., workflow bottleneck, unclear form).
- Revise the batch record form to require time and signature fields with a hard stop.
- Retrain staff on documentation requirements.
- Audit a sample of recent batch records for similar gaps.
- Document the corrective action and monitor compliance.
Model answer: Apply USP <797> documentation requirements, complete or discard the unverified bags, and implement a root-cause analysis and audit.
