We´re looking to start measuring nursing workload in high complexity units. There´s evidence of the application of TISS - 28 in cardiac surgery patients but i´m not 100% sure if there is any incovenient to apply in other non surgical cardiac units.
I don't think TISS28 is validated for Cardiology Units. But if its for your own purpose you can modify the scoring list !! If you start with the TISS-76 you probably cover most of your activities.
Thanks Dr. Bakker! The idea is to apply it in all of our medium - high acuity units (medical, surgical, cardiac surgery recovery, coronary and neurological unit).
The limitations of the TISS-28 is it is based on how we provided critical care 20 years ago. A great deal of nursing care has changed since then that are not captured in the TISS-28. For example we keep patients more awake, promote more mobilization than before yet these items are not captured in the TISS-28. I would argue, because it misses important advances in critical care, it has a tendency to underscore workload.
Saying that, this tool does have a lot of validity and reliability evidence in ICUs around the world.
Dear Vini, I agree with you that TISS 28 perhaps is not the best tool for a reliable nursing workload measurement. A great part of our work like management issues, service and procedures coordination or taking care of patient's relatives is not adequately reflected in current tools, maybe NAS.
