I think one reason that the PT profession is more likely to lend itself to having its practitioners spending time preforming "unskilled" tasks is that PT is something that occurs in relatively long sessions over an extended period of time. A pharmacist, a dentist and a surgeon all have a very specific task they are going to perform as a service to you all at once. Because of the nature of their work they very rarely would spend enough time with each client in the first place to even have the opportunity to "waste time" with their clients like a PT might have the opportunity to. A pharmacist is only going to spend a couple of minutes with someone a best. A dentist might spend a couple hours working on you, to get done what needs to be done. Same thing with a surgeon, just however long the surgery takes. But if somebody has a massive stroke or a TBI PTs will probably spend over 100 hours with that person without even breaking a sweat, over the course of months. So there is more time to be filled and more opportunity to fill it with "unskilled" work. Should PTs watch the way their patients are doing their HEP exercises periodically to correct bad form as needed, make adjustments, etc. Yes of course that is an absolute must. But because a PT has to do that, there is an opportunity right there for the PT to end up standing watching someone do shoulder pulleys for 15 mins. I have been to some clinics where their sales pitch is that they only employ PTs, not techs or trainers. While in an ideal world I would rather have a PT watch me do all my exercises for the session, just in case I am doing something wrong, that is wasteful. I think this is more likely to be a concern in the inpatient settings as outpatient settings generally have more patients and are populated by a lot of techs.
