Temperature monitoring of pharmaceuticals in medical fridges, freezers, storerooms and during distribution helps to verify that they are stored within the specified environmental conditions.
It is essential that pharmaceuticals are stored within the
correct temperature range to ensure their safety and effectiveness.
Tayside Pharmaceuticals is a 'Specials'
manufacturer making bespoke medicines for the NHS in-house. The
company uses Tinytag data
loggers to help confirm that medicines and
vaccines are stored under the correct environmental conditions
in all areas including fridges, freezers and storerooms, so that
they remain an effective treatment when they reach the patient. The
monitoring also extends throughout the cold chain
from dispatch to the dispensing pharmacy. The company has
responsibility for the environmental monitoring of clean rooms and
medicine storage within their own premises and also in the pharmacy
departments throughout NHS Tayside.
In total, 81 Tinytag Ultra 2
temperature data loggers are in use. Of these, 29 are
permanently committed to monitoring specific storerooms, cupboards
and clinical trial materials. The remainder are deployed according
to a monthly plan for monitoring different on- and off-site
locations. These include, variously, medicines store rooms and
cupboards, pharmacy dispensaries, fridges, freezers, media
incubators, laboratory drying ovens and pharmacy dispensing robots.
These areas are also monitored with data loggers on an ad-hoc basis
should an abnormal temperature event occur.
The data is used to evaluate the temperature range over
an area for a period of time, usually a week, with
specific regard to any hot or cold spots, and to verify overall
that these areas comply with the limits placed on the specific
storage for the monitoring period. If a controllable store is found
to be out of limits, the stock inside must be scrapped, the store
repaired or condemned, and new stock sourced and stored in an
alternate controlled environment.
David Hall, Quality Assurance Technician at
Tayside Pharmaceuticals, believes the primary benefit of using
Tinytags is the functionality of the
Tinytag Explorer software,
which is simple to use, but comprehensive enough
to show the data fully in an accessible format. David also
comments, "The battery life of the Tinytag loggers is
very useful, especially for longer term projects such as cold-chain
mapping. We are exceedingly happy with the results and accuracy of
these loggers, and their download speed makes results obtainable
