I very clearly said 90% of HCAs i have worked with are amazing and undervalued for the role they do in the hospital. But some are not. Ive worked in my dept long enough to know which few, a small minority, i wouldnt ask to do obs having seen them document incorrectly. But they are untrained, and if something were to happen to a patient in my care and obs were not correctly recorded, its my PIN on the line, not theirs. If someone is clinically unstable i would not ask - and nor should a HCA be responsible for doing those observations.
I also was a HCA, for over a decade, prior to my nursing, in an acute hospital setting, and for the vast majority of my time as an HCA, observations were not part of that role. I took on that role in my latter years, alongside many others that should really be a nursing job due to changes in roles in the whole hospital setting and nurses no longer having time to d it all themselves. I believe they still shouldnt be part of that role unless they have been trained and are in a band 3 or 4 position and have the title of CSW or NA or the old AP's. Same as i dont agree with HCA's at band 2 doing venepuncture, categorising pressure sores and simple dressings, doing ECGs etc etc. As a band 2 if you are being asked to preform these, i firmly believe you should be questioning your banding, receiving some formal training through your trust, and being paid accordingly with the responsibility that is being placed on you.
I have nothing against HCA's at all. The vast majority i have worked with and alongside are worth their weight in gold and a hospital would not function without them.
