I have a recent experience of seeking opinions about a HCP. A couple of my friends in the village warned me that our local health visitor was a bit of a cold fish, and didn't really make it seem like she was interested in people's children. So I went to one of her clinics, found that, yes, she comes across as very uncaring and distant, so I go into the nearby town to a baby clinic there, with a lovely HV. I've mentioned to my MW and GP that I find this HV difficult, and this has been added to some other complaints from our area.
However, a personal attack on this person on t'interweb would, in my opinion, be cruel. She needs a bit of advice from her peers, and perhaps some retraining, not lambasting in cyberspace, which would forever tarnish her reputation. And, as I'm sure we all agree from experience on this site, people tend to be far more insulting and, yes, downright bitchy, when they have the security of internet anonimity to hide behind.
I also have switched GPs when I simply didn't warm to the one I was allocated. But that's why surgeries have several GPs and the option of changing. If one particular GP is often refused by patients, it's down to the practise manager to identify a problem and follow it up.
I agree, Justine, that for consumer goods and services, internet reviews are the way forward. But for something as serious as medical provision, there should be correct channels and procedures, subject to legistlation and governing bodies. This site just serves to undermine those.
