Maintaining recommended temperatures is essential to ensure the efficacy of vaccines; Tinytags record data to help verify that vaccines have been stored correctly and help meet SEQOHS accreditation standards for cold chain and vaccine storage.
The 5 Boroughs NHS Foundation Trust Occupational Health
Department is a mental health trust covering Warrington, Wigan,
Leigh, St Helens and Knowsley. The Trust is using Tinytag
temperature data loggers to monitor departmental
vaccine fridges, and cool boxes used to transport vaccines
taken off site.
Temperature monitoring is vital to ensure vaccines remain
effective. Many cannot remain at room temperature for long before
they have to be discarded, and there is a huge cost implication if
this occurs. The Trust is SEQOHS (Safe, Effective, Quality
Occupational Health Service) accredited, and using the loggers
helps it to meet the recommendations within the accreditation
standards for cold chain and vaccine storage.
There are two Tinytag
View 2 data loggers in use, one in each vaccine fridge. They
are used as a back-up on a daily basis, in conjunction with the
temperature gauges already in situ in each fridge. The fridges are
checked daily and the temperatures recorded; in the case of any
discrepancy, the logger's information is downloaded. The Tinytags
record the temperature every 10 minutes, so it is possible to
pinpoint exactly when and for how long the fridge/storage has been
out of range.
There may be a need to remove and destroy any vaccines that have
been stored at the incorrect temperature, whether that be above or
below the recommended range.
Monitoring also provides important information indicating how
long the fridge door has been open during a stock-check. This helps
ensure that the pharmacy and nursing staff do not allow the door to
be opened for extended periods and can demonstrate why. Tinytag
loggers remove any guesswork regarding fluctuations in temperature
The Tinytags are also used in cool boxes for outreach
clinics during flu vaccinations, and for external clinics where
other vaccines are used (e.g. Hepatitis B vaccines). If
the logger shows the temperature of the cool box to be above the
upper recommended limit of 8°C then the vaccines are discarded.
Nurse Team Leader Diane Williams chose Tinytags due to their
flexibility and is very satisfied with the results. She comments,
"They are small and easily
portable, and can be set to record temperatures at
any chosen interval and this can be changed as required.
They can have alarm limits set, the batteries are
long-lived and the software is easy to use."
