Why was it done?

The aim of this work is to find a cheaper alternative, reducing the analysis duration and allowing the pharmacy to be laboratory independent.

What was done?

The opening of the production unit (PU) leads to reorganize the parenteral nutrition mixtures (PNM) dosing. Primarily carried out in the biochemistry laboratory of our hospital, potentiometry and colorimetry analysis were long (more than an hour) and costly. PNM composition accelerates the aging of one of the device components that costs 1400 euros and have to be changed every 3 weeks, raising the total around 24300 euros per year only for this component.

How was it done?

Hospitals producing PNM in the region were identified and approached. They were asked about the type of dosed elements, the analysis method and the equipment used, about the analysis duration and localization (laboratory or pharmacy departments) and their overall cost estimation.

What has been achieved?

Five hospitals with different dosing equipment answered. Four of them analyze cations: calcium, magnesium, sodium and potassium by capillary electrophoresis, potentiometry or spectrometry, three of them analyze glucose by chromatography or colorimetry, and two of them determine osmolarity of the PNM mixtures. Dosages are performed by the pharmacy department in three PU where technician are required. Results are provided in about an hour when the activity depends on the laboratory and around five to ten minutes when it is managed by the pharmacy department. The average cost to purchase the equipment for each hospital was around 50000 euros (without the associated materials and the labour cost).

What next?

To conclude, no hospital interviewed can be a model because of either the high costs or the unadapted equipment size to the scale of the room of our PU. Nevertheless, during discussions, an equipment that might answer our needs was suggested, because no technician is needed for analysis, and it is described simple and easy to use. The manufacturer has been reached out asking for demonstration and information before any purchase. If accepted, the device will be qualified before going into production.

EAHP Forum

All the EAHP team is working on providing a Forum that can help connect all the members in Conversations and Groups to talk about important matters for the European Hospital Pharmacist.

The Forum will be accessible for all the EAHP members, you don’t have to create a new account to browse and participate.

Conversations and groups

The Conversations will be moderated by our team to provide documents and relevant topics for the community.

The Groups will connect all members that share a category. Members who work on the same assocation, on the same hospital, that have the same role, etc.

Stay tuned for the realase of the forum. Soon on EAHP.
