I'm in about 5 minds when it comes to the NHS... But overall, I am happy to pay for it and am very very glad it's there!
Daughter is a "cast iron" coeliac. Took her to give blood some time ago (I make them go a couple of times to qualify them for receiving any!) and the blood people just about called an ambulance, she was so anaemic. They took bloods and told us to get to the GP Went to GP on the Monday and he basically told her to eat more meat (she eats everything we put in front of her) He couldn't believe she was so low so sent her bloods away. Both sets of results came back confirming it. GP stuck her on iron supplements and when asked what was the cause just shrugged... Iron for 6 months, bloods ok, came off iron for 6 months, got anaemic again. repeat for 2.5 years... Eventually got concerned about lack of progress and ante'd up and went private. Doc did some tests and said, that looks like you are coeliac but if you want we can do a 'scopy and make sure. She said yes and they took a biopsy which confirmed a lot of inflammation and that the little wavey fingers in her gut (villi) were pretty much stumps. This lead to lack of nutrient uptake especially iron. She now has the option to get GF food on prescription but we only get a couple of loaves a month as we can't get the nice tasting stuff in the supermarket. GP should have thought about it a bit more rather than just dish out iron tablets for the next 80 years....
Father in law got nailed by Vasulitis, Wegener's flavour that went into his lungs. Rushed to hospital straight into ICU, induced coma the lot, oxygen sat levels dropping by the hour. Not responding to antibiotics so docs consulted and thought it might be vasculitis. Treatment is massive amounts of steroids to nuke the immune system, it's an auto-immune disease, If they nuked the immune system and it was an infection then he would die... If they didn't, the way the O2 was going he would die. The Doc had a serious discussion with wife and sis-in-law and talked through the options. They had a couple of things to try but didn't have the time. Doc was pretty sure it was auto-immune but they had to make the call. He was right. That was 6 years ago, the old bugger is happily still driving us crazy. He was in ICU with 1 to 1 nursing for about 2 months then into High Depandancy. Outstanding job!
Wife is a Dentist in the NHS, she trains student dentists and then does community work when they are not there. She used to have her own practice but sold it due, to shall we say 'musical differences' with her biz partner. She was doing between 20 and 30 patients a day as a NHS dentist but cared more about quality of care than the cash, hence the 'musical differences.' It was not making a loss!!
There are people in the NHS service who are fantastic, care focused, dedicated individuals who are just trying to do a good job and help people, these people are the NHS. There are others who are a disgrace and unfortunately they are not an insignificant proportion. Individuals who are too large/incapacitated to get to the canteen at lunchtime and call a porter to wheel them up in a chair and sleep at other times.... Individuals who have bullied others to the extent that it may have contributed to them taking their own lives. Individuals who don't want to treat patients but are paid for a clinical role, they would rather do management tasks but rather like the money. Individuals who feel the need to discipline others for making two trips out to see a child rather than one. Despite the fact that it was after hours and they had been called by the parents as the kid was having problems with their line, eventually was told they couldn't claim expenses on that trip.... Managers who can't manage so have staff bring in their cars (and claim expenses) to fill in gaps due to lack of planning. People off on the long term sick for physical issues and having vacations in New York and Disney Florida...
The problem I have with the NHS is it's inefficiency and its inability to discipline/fire people for persistent abuse, it's deemed a job for life and usually it is.
As for the US healthcare system. Overtreatment and overcharging is the issue there. Cousin stood on a toothpick in his bare feet. Not too serious, between the toes. Tried to pull it out and a bit got left in.... Went to hospital, not the ER. Nurse went in with a pair of forceps and removed it. Cousin declined a local as it would hurt as much as them going in with forceps. $1600.. I think he may have paid for antibiotics on top of that.
Yup NHS, IMO overall a splendid thing superb for acute care, not so good for chronic care, it's simply too expensive
Back to the OPs post, I think you have heard the answer a few times, the kits might be a good indicator but follow up with your GP. We have found the BP things pretty good (comparing them to NHS instruments)
Cheers
