Here's the problem with this, it probably WONT be quicker, because the CNA/PCT/PCA might have 15 other patients(and their families), all of whom are going to be hitting call lights for anything and everything, and nurses asking them to do this or that...in between checking vitals, I/Os, feeding, bathing, ambulating, toileting, repositioning, checking BGL, emptying tubes and drains, suctioning, ISC, bladder scans, enemas, restocking, labs, EKGs, and on and on and on. PCTs/techs and CNAs are already massively overworked as it is. Every time Id come out of an isolation room after doing a bed bath or something time consuming, id check my pager and buried in between a couple dozen call lights/monitor pages id have 2 or 3 frantic pages from RNs demanding I (insert time consuming menial task).
I have far more responsibility now working as an RT, but I still generally find the job less stressful and more rewarding than my years as a tech/CNA, so I'm not sure dumping EVERY backbreaking or menial task onto already overworked and underpaid CNA/Techs is really the best solution.
In press ganey surveys the techs always got crucified by patients and families, because they never realized the tech had 5 times as many patients as the RNs, so they just assumed the techs were lazy or negligent. I don't know how many times when I started the shift the patient would complain I barely saw the previous tech. A couple times I actually had patients and family chastise me because the poor RN with her multiple patients(3) had to do something while I, their personal patient care tech( I had 16 patients but they assumed I was assigned only to THEM) was probably playing candy crush.
