One question in my mind is at what point does coercion start.
What is the difference between a doctor persuading a patient to have a particular therapy and for the patient to be coerced into it. The phrase 'you do want to get better' comes to mind, What if the positive outcomes are over spun and dangers underplayed so that someone accepts a treatment they wouldn't normally choose. Is that coercion.
Dispite this debate I've not seen anyone talking about the ethics of medical practice and when persuasion or advertising becomes coercion. Just a debate saying government shouldn't coerce.
and, slightly O-T, is it right for a doctor to refuse to order a test on the grounds that a patient has stated that they are not prepared to use a particular type of drug? This has happened to me when I asked for a bone density scan, having suffered an unexpected (my first) fracture a few years previously and wanting to know whether I needed to continue supplementing bone minerals. Foolishly I had told the doc that I wasn't willing to take bisphosphonates, following which he refused to order the scan, saying that there was no point if I wouldn't take those drugs.
I'd also be interested in what treatments would be insisted upon for obese patients. Physicians' First Watch recently reported that no recommended diets produced lasting weight loss. It seems to me that the only clinically-approved treatment that works is bariatric surgery. So are they going to insist on that, or deny benefits? It makes no sense, as many obese people are in work, including some MPs and government ministers!
BTW I achieved my own weight loss (from near-obese to sustained normal weight) by cutting out gluten and reducing sugar and grains, but I somehow doubt whether any NHS doctor would recommend that.
