Case study
Safeguarding the vaccine cold chain at a health centre
A health centre where the cold chain relied on a sheet filled in morning and afternoon, with all the risk concentrated in the hours no one was looking.
A representative scenario, built from the problems we see most often in this kind of site. Exact figures vary from one installation to another.
Starting point
The centre has a vaccine fridge, a freezer and a blood-bank cold room, fed by the public grid with a backup generator. Readings were taken by hand, twice a day.
Main problem
A power cut at three in the morning or a door left ajar only showed up at the next reading, by which point there was no way to prove the batch had stayed within range all night.
Solution put in place
Temperature and door probes on every unit feed COA Saúde, which shows the whole cold chain on one screen and alerts the on-call team as soon as something drifts out of range, day or night.
Key results
In the first six months with the system running:
batches lost to a cold-chain failure
response time to a night-time alarm
of units with a record ready for audit
Day to day
What the team sees on screen
COA Saúde — Cadeia de frioThe full cold chain, from the public grid to the fridges, with the power source in use.
Frigorífico de vacinas — FichaThe vaccine fridge's record: temperature, door and the batch in storage.
