Ch-1 Is the monitoring of your medication and food fridges doing what it should be doing?

With new IoT technology we are able to take a closer look


We are all familiar with the current approach. A couple of times a day a staff member goes round the building, opens fridges, reads a thermometer and writes it down.

The basis for this approach has always been the supposition that fridges are boringly normal and maintain the temperature between certain limits. The checks are just nominal.

What would happen if one day staff logged a fridge at 17 deg? Are medications OK ? Food stuffs? Who actually raises the alarm? Staff or Nurse manager after reading log book?

Is medication damage limitation too late? It begs the question ”How long has it been like this? Nobody knows

Later on we take advantage of new technology to actually check the life of a fridge or chiller 24hrs a day.. Are these fridges really boring or do they have a life of their own?

One of the early pointers that came out of the study was that if a fridge was never opened it was fine. Barring mechanical failure, it was OK. It motored along nicely. The only trouble with that, is that in real life the fridge is not doing anything useful.

No door opening, all is good

However it did raise one flag. If a fridge was likely to go out of limits, it would probably be due to daily traffic. Human and physical intervention. We needed to do further testing using working fridges. We needed to check whether there were exceptions going on, but the twice daily checks were not logging it.

Why does this happen?. As suggested previously, it is primarily due to user access to fridge. And we also noted two or three common factors that could cause an exception.

But the results confirmed that there were exceptions happening which questioned the fallibility of those twice a day temperature checks

Qu 1 Further on we will look at other implications of this project. Because medication is a low mass product, it will react more quickly to temperature variation compared say with a litre of milk.

Qu 2 Why do we wait for a report of fridge malfunction?. IHistorical reporting is too late. The damage is done and report unhelpful. Should fridge monitoring be pro-active and react to first evidence of escalation. And nip it in the bud.?

Qu 3 Is there a case for relieving staff members of of this task and looking at better ways? Twice a day does not fit the bill. This modus operandi has been the norm for many years gone by. But now there are better ways.

Message from John Williams CEO,

If you want to have a look see at what your fridges and cold storage are reporting 24/7, then we can loan you a no obligation test kit. See contact form and check option ‘Test Kit’ and we will arrange delivery details with you
