Those who are using central temperature monitoring(CTM) as their primary method to monitor blood bank storage equipments, I have few questions :
1) Do you still use charts? Yes, as a backup. We recently had the wireless temp monitoring (we use Mesa) go down for about 12 hours, so it's nice to show constant monitoring. But most of the time, it's overkill.
2) Do you take daily recording? Yes. We record digital reading, Mesa reading, and check that the chart reading, just to make sure they correlate. We do not check thermometer temps in the equipment, but have thermometers in there for troubleshooting purposes in case we get a Mesa alarm.
3) If you take manual recording, which readings? See above
4) How do you monitor your CTM? Every morning a Blood Bank tech looks at the list of BB equipment and makes sure everything is "in the green". Weekly we print the graphs from Mesa and staple our charts to it. I really hate printing when we have an electronic system, but we had an inspector who really likes paper (ugh) and pointed out that we could change systems in the future and would not have access to previous data if we no longer have access to the software. We also do quarterly alarm checks and annually we check our certified thermometer against each Mesa probe for accuracy.
5) What kind of reports do you print? Weekly graph showing that temps were in range for the entire week.
6) Do you run into problem where you do not have readings and do not have charts? No. That's why we still do the charts for when Mesa is down.
We are super happy we have this system in place. It really works amazingly well and gives you a real sense of confidence that your blood and reagents are safe 24/7.
