Why was it done?

The purpose was to find data for an increased microbiological shelf-life of preparations of cytotoxic agents in infusion bags combined with medical devices. The aim was to increase microbiological shelf-life from 24 hours to 7 days. Existing data were studied to find evidence to support the prolonged shelf-life.

What was done?

The purpose was to find data for an increased microbiological shelf life of preparations of cytotoxic agents in infusion bags combined with medical devices. The aim was to increase microbiological shelf life from 24 hours to 7 days. Existing data was studied to find evidence to support the prolonged shelf life.

How was it done?

A team from the production and quality assurance departments worked together on writing a report that could provide the rationale for the change of shelf-life.
We collected data from
– supplier qualification of the medical devices
– aseptic process simulations (APS)
– process validations
Data were evaluated and risk assessment was performed.
Six medical devices were included.
All suppliers were qualified as low risk.
APS for the specific production process showed no growth.
Process validation data for two types of medical devices showed no concern regarding sterility of preparations.

What has been achieved?

The increase of shelf life was accepted. First product was Blincyto® in infusion bag with Take Set Swan-Lock ® with shelf life increased to 4 days. Patients now visit the oncology clinic only twice a week instead of daily thus saving time and transportation.

What next?

The result means that new product implementation is quick because the only things to evaluate are the stability of the substance and the compatibility of this with materials in contact with it.

Deadline extended to July 15th

Problems caused by shortages are serious, threaten patient care and require urgent action.

Help us provide an overview of the scale of the problem, as well as insights into the impact on overall patient care.

Our aim is to investigate the causes of medicine and medical device shortages in the hospital setting,  while also gathering effective solutions and best practices implemented at local, regional, and national levels.
