It costs less to hire a pca with a couple of lpns supervising than it does to have a staff of rn's and most of the RN'S didn't have much choice about whether they wanted to continue working in patient care or go into other lines of work (at least here in Alberta). LPN's have taken over the role many RN's used to play, with perhaps a couple of RN's supervising on the ward. And more PCA's are being used to provide direct patient care.
LPN's are generally very well trained and standards have been set for some time. They don't follow a standard curriculum, but certification is overseen pretty closely by their professional body. And I assure you that they cover handwashing technique, as well as the five rights of medication administration. It comes up in their clinical as well as their academic work.
PCA's (or HCA's) in Alberta vary. I don't think they had a professional body until recently (I could be wrong on that), and have had a standardized program of study for only a year or two, whatever its flaws. Until recently many care attendents were trained on the job, mostly in long term care institutions, and weren't really required to have any certification. Of course, if someone is trained 'on the job' there is no control over the skills that they learn, or don't learn. That is changing here, but it takes time. For those already working in health care, given the shortage of health care workers, many got equivalency in certification, which involves both clinical and knowledge assessment. In some cases it required partial or complete retraining. I'm more inclined to believe that they would have 'knowledge gaps' which might lead to improper technique in day to day practise. (The testing situation might be a bit different, of course.)
I'm not sure, on reflection, whether a PCA, or an LPN going for equivalency, will actually be flunked if they don't wash their hands during the clinical assessment. I'm inclined to believe the evaluator would note it, tell the applicant, and pass them if they did everything else right. I should ask about that.
So I know the training standards are going up, but I believe that is mostly established at the provincial level, so there is some variation across Canada. Dora
