Why was it done?

In the oncology pharmacy, isolators are vital for aseptic compounding and operator protection. However, daily handling steps can still introduce contamination risks and affect patient safety. We recognized the need to systematically analyse and minimize these risks, especially in a resource-constrained setting, to ensure safer and more standardized chemotherapy preparation practices.

What was done?

We applied Failure Mode and Effects Analysis (FMEA) to identify and reduce risks in isolator handling during chemotherapy preparation. The objective was to evaluate each step of the process, implement corrective measures to lower risk priority numbers (RPNs), and develop a practical model that could be shared with other hospital pharmacies.

How was it done?

An observational checklist was used to evaluate six key isolator handling steps: glove installation, surface cleaning, material transfer, logbook entry, waste removal, and glove removal. During 100 routine preparations, failures were recorded to calculate occurrence scores. Severity and detection were assessed by an interdisciplinary team, and risk priority numbers (RPNs) were obtained by multiplying severity, occurrence, and detection scores.

What has been achieved?

The analysis identified surface cleaning, material transfer, and glove installation as the most critical steps, with RPNs of 240, 210, and 144 respectively. These represented the main contamination and safety risks. After implementing targeted corrective actions, including improved procedures and staff awareness, we projected significant reductions in RPNs to below 80, confirming the effectiveness of the intervention.

What next?

We will continue to apply and monitor the corrective measures through updated SOPs, dedicated monitoring tools, and continuous staff training to ensure sustained improvement. This initiative offers a transferable model that other oncology pharmacies can adopt to harmonize practices and strengthen patient and operator safety in chemotherapy preparation.

Why was it done?

– Optimize the workflow:Nursing staff are independent in final product quality control.Dissapear the manual register of compounding sterile preparations.Fewer mixtures are discarded.Also in Pharmacy Service only elaborate the sterile preparations with an economic and safety impact.

– Improve the safety of drug administration in pediatric patients: there are ready-to-use commercial parenteral presentations, which can lead to errors when dosing per kilo,fe: enoxaparin…

– Optimize economic savings:all excess vials are reused

What was done?

Previously,some parenteral drugs were compounded at Pharmacy Service.The rest of the vials were discarded daily,so the pharmacist had to anticipated some elaborations not to throw,so then some were suspended.
Also, the pharmacists done the final product quality control,it could be delayed the dispensing and specially when it´s necessary to repeat the mixture.

The changes were:

– Re-selection of the parenteral drugs compounded at Pharmacy Service by:
• Economic criterio:the cost of drug has to be >20 euros/vial
• Safety for the pediatric patient:redose individually parenteral drugs “readytouse”

– Review the storage conditions:physicochemical (technical data sheet drug,Stabilis web) and microbiological stability (Good practices for preparation drugs in hospital pharmacy services publised by Spain Goverment) of all parenteral drugs previously selected.Although the physicochemical stability is higher,the final stability will be limited by the microbiological stability and the risk level microbial contamination(USP 2004).

– Standard Operating Procedures with structured and updated information

– Reuse of partially used multi dose vials:we reviewed the physicochemical and microbiological stability of open vial

– Final product quality control by nursing staff

– Save time to pharmacist:daily scheduling instead of anticipated elaboration of sterile preparations

How was it done?

– A nurse involved in the circuit change giving her feedback on the changes

– Traceability of the rests of the vials:stickers are affixed to the opened vials indicating the reconstitution data and the expiration date

– Final product quality control should be done by a diferente nurse to elaborated to detect potencial errors

What has been achieved?

The total cost savings for this year is 295.778€. After the circuit´s change, the savings have increased by 55% for liposomal amphotericin b, 51% defibrotide, 24% micafungin.

What next?

Compounding sterile preparations individualized in Pharmacy Service to patients hospitalized at home, transplanted of hematopoietic progenitors and immunocompromised
