'It certainly left me feeling good about the NHS. I do believe it is a great institution'

Paul Smith, 34, learning difficulties nurse

It is a fear that we may be moving towards the American system, but I think in Britain we always fear things like that.

Doctors in the British system are very efficient in terms of the number of people they see, but they spend a lot less time with each patient than in the US'

Karim Ahmed, 34, A&E registrar

I really enjoyed the film, but in terms of the health service it is obviously showing just the very best side of our NHS and the very worst parts of the US system. I came away feeling that what we have here, the basic principle of the NHS, is a very good thing, and that it is up to all of us to work really hard to make it better. We need to concentrate on getting the quality up, but I think that is achievable.

Of course we don't fund the NHS properly. Americans pay far more for their health service than we do; the tax we pay here is really not much compared with what they pay in insurance premiums. In lots of ways we are a long way behind the US system. For example, we are pretty good at accessibility - doctors in the British system are very efficient in terms of the number of people they see - but they spend a lot less time with each patient than in the US. And my impression is that there are generally more resources per patient in the US than in the UK: more doctors, more nurses, more beds. The problem they have, of course, is that access to all that is just not equitable. Although there is a trend in terms of our overall economic ideas towards America there would be a lot of resistance to moving to an American system. The government may look towards it for getting extra funding in the short term, but there is a huge amount of resistance from the public and the NHS itself. Even though there are advantages in terms of pay and conditions people are still staunchly supportive of the NHS and worry about private finance initiatives.

'I don't think we'll end up going to the extremes of the American model; people simply wouldn't put up with it'

Zhaleh Khaleeli, 32, researcher

Overall the film is a good thing - Moore is bringing a lot of issues to the attention of the American public that they probably would not think about much otherwise. But it doesn't translate that well over here. We're used to a bit more sophistication, we want both sides of the picture. As far as the NHS goes, you can see he is glossing over all sorts of problems. That said, it makes you realise how lucky we are. We all moan about the NHS, but watching this film makes you realise how fortunate you are. By and large most UK doctors feel at home with the NHS model; you can treat whoever needs the treatment, without any monetary considerations. Doctors in the US must have to compromise their ethics; it would be hugely frustrating for us to work in an environment where you have to turn people away because they don't have the right insurance. And the other side of that coin is that in the US people who have good insurance are often over-investigated, to make money.

Of course there are many areas for potential improvement in the NHS; there has been an emphasis on making things "appear" better, by cutting waiting lists and improving performance targets and so on, rather than on improving medical care. And there are big problems building up because of the overhaul of medical training; a lot of people are worried that patient care will be compromised by faster training and less experience.

I think there is a danger that we could go more like the American system. There's certainly much more private involvement in the NHS now, and it hasn't been very successful. I hope people will resist any more moves in that direction. But I don't think we'll end up going to the extremes of the American model; people simply wouldn't put up with it.

'The NHS system where you pay £6.65 for virtually any drug is pretty amazing'

Muna Ahmed, 32, clinical genetics specialist

You get the point of the film pretty quickly: the US system is terrible unless you've got lots of money. I don't think I could be a doctor in a system like that of the US. The film reinforced my view that the NHS is a world-class system and I'm really proud of it and really proud to be working in it. But I can see that even for someone very pro-NHS, Moore's portrayal went a little over the top. It was very rose-tinted. But people do get very good treatment in the NHS. The service is absolutely fantastic. People complain, but it's usually about the waiting; once they've actually seen someone you hardly hear any complaints. A system where you pay £6.65 for virtually any drug is pretty amazing. From the doctor's point of view it is not bad either; there certainly are GPs who earn £85,000 and have the kind of lifestyle of the NHS GP in Sicko.

One thing I would say, though: all those caricatured American fears about "socialised medicine", with the government telling doctors where they have to go and what they have to specialise in, is becoming true here - the new applications system [for junior doctors applying for training] is an absolute nightmare. You have very little choice now. It wasn't like that in the past, and in the long run the NHS will suffer for it. I'm London born and bred, and I have no option but to move to Manchester for my career.

'No one who works in the NHS would pretend it's perfect'

Ben Maguire, 28, capital programme manager

Moore does paint a very black picture of the US system and a very rosy one of the NHS. Even if we recognise what a great institution the NHS is, no one who works in it would pretend it's perfect. There are funding problems; there are issues around schemes such as PBR [payment by results] and referral thresholds and so on. Overall, I feel that in the US it often seems as if businessmen are trying to run medical clinics, and in Britain it can sometimes seem as if clinicians are trying to run businesses. I'm sure there's a happy medium to be found.

'I don't know how American doctors can work in a system that means they have to turn people away'

Haseena Iqbal, 30, GP

The film was an amazing eye-opener. Of course you see things in the media, but you really get no inkling of what the US system is really like. It is astonishing that a country can be so advanced in some ways yet its health system can be so backward. Moore's basic point is very simple: the NHS is free at the point of use, and crucially, as a patient you will get seen. I don't know how American doctors can work in a system that means they have to turn people away. I've always thought the NHS was a very, very good system but, in fact, the way it's going, plenty of people are beginning to lose confidence in it. The core concepts are still absolutely valid, but doctors, for example, are beginning to get very disgruntled about the way jobs are allocated. You always used to be able to choose what specialism you wanted to pursue, what area you wanted to work in; these days government control over doctors' careers is increasing, as is the paperwork and the bureaucracy.

'I really had no idea that US patients can just get kicked out of hospital, put in a taxi and dumped on the street'

Shazia Jalali, 29, GP

Some of the film was absolutely unbelievable. I found it really hard to understand how you can have such a different ethos in the same profession. You could never imagine anyone in a British accident and emergency department saying to a patient, 'You'll have to choose between us reattaching your ring finger and your middle finger according to how much you can afford." And I really had no idea that patients can just get kicked out of hospital, put in a taxi and dumped on the street. It was really tragic. But it certainly made me feel very good about the NHS, and about our society in general. We may moan, but by comparison Britain is so much more fair and egalitarian. It also made me feel very proud to work in the NHS: yes, there are waiting lists; yes, there are funding issues; yes, there are problems, particularly with patients with non life-threatening conditions. I have a patient who has been waiting for a hearing aid for three years and that is just unacceptable. But they are all relative.

On the other hand, American fears of "socialised medicine" and what it means for doctors' freedom to choose what they want to do and where they want to do it are beginning to be realised here. Nobody used to complain about not having a lifestyle choice; now they do. It is also true that there are some complex changes being made to the NHS with very little forward planning or thinking on the part of the government. For example, in Brent over the past couple of years a very large number of our new patients have been from eastern Europe, which is fine except that Brent council chose that moment to withdraw interpretation services. That kind of thing is just depressing.

'I much prefer the British system. In spades. We have huge advantages, and a lot of people get treatment who wouldn't otherwise'

David Curtis, 47, consultant psychiatrist

The film was very one-sided, but a number of the points it made were valid, such as the advantages of a government-managed universal healthcare system as opposed to a patchier system provided by HMOs [health maintenance organisations, which provide healthcare to consumers for a monthly fee]. Healthcare can be so expensive that an individual can't really afford to manage that risk themselves. What we saw with the insurance companies is that they were only insuring low-risk people; in a government, tax-funded system, the risk is spread out evenly.

Having said that, the Republican party had perfectly valid objections too: do you want the government to be in charge of healthcare provision? Do you want the government deciding what treatment you can get, where a doctor can live, where a doctor can work? What we have now is a situation where provision of healthcare depends on political will. Take some of the American arguments about whether or not a treatment can be provided - one can see similar arguments in a government-funded system. There is still a drive to contain costs, and though it is not as intense, it does not disappear completely.

I much prefer the British system. In spades. We have huge advantages, and a lot of people get treatment who wouldn't otherwise. We have more emphasis on preventative medicine, so we have better overall levels of health.

It is true that Moore chose an easy target, because he used acute casualty departments - we've always known the NHS is good at casualty. If he had done this film 10 years ago and someone had an arthritic hip, he would have heard a completely different story. Things have improved an awful lot, although one of the areas where you still see the longest waits is in psychotherapy. I think that is one of the places where it is going to be most difficult to deliver target times, and where the biggest change will come. In America, you could see an analyst tomorrow, if your HMO would pay for it. In Britain there are quite long waits for psychological treatment.

A lot of good stuff about the NHS did not come through either. For example, working in psychiatry often involves working in a multidisciplinary team in the community - doctors, nurses and social workers thinking of every aspect of a patient's wellbeing. I think Britain's welfare state does a very good job of that sort of thing, and I'm very proud of that.

There was some talk about Kaiser Permanente (a US healthcare corporation) here a while ago. Some people talked favourably about the way these companies work and said the NHS should work like that and it was much cheaper. But doctors have less clinical freedom and there is an expectation that the patient should be out after an operation in three to five days and it is a problem if they are not. I think this is potentially worrying. British doctors feel unease about that and feel they would be under undue pressure if it was adopted.

'The American system seems good only for the rich'

David Wilson, 20, pharmacy student

I found it shocking how bad the American system is. I knew they had challenges but I didn't realise you could be refused treatment. It seems unethical to me. The story of the little baby dying because the parent didn't have insurance for that hospital; it was terrible. That wouldn't happen in the UK.

The American system seems good only for the rich. I find it hard to find any positives in it. I've taken the NHS for granted in the past - now I realise how much we should appreciate it.

'Especially in emergency situations, the NHS is really good. Kids are generally well looked after too'

Stephen Whyte, 22, hospital pharmacist

I've always thought the NHS was a really good thing but when you see the American health system against ours, it really makes you feel grateful for what we've got.

People are quick to complain about things, especially waiting times and things like that, but when you get it into perspective - for example the woman in the film with broken ribs who went to hospital, and just because she didn't have insurance she was flung out on to the street - you would never see that here. Especially in emergency situations, the NHS is really good. Kids are generally well looked after too.

Working for the NHS isn't the most financially viable thing to do: I've recently qualified and a newly qualified pharmacist can make £15,000 more working at Boots or Lloyds. It was a deliberate choice for me - I think job satisfaction is more important than money in the bank at the end of the day.

I think people should watch Sicko - especially people who are sceptical of the NHS. Hopefully it will make them proud of the system we have instead of constantly running it down.

'Thank God for the NHS. Thank God the NHS didn't go the American way'

Ehsan Khondaker, 33, GP

It's incredible in this day and age, when we look to America for so much in the way of inspiration and ideas, that it should be ranked 37th in the world when it comes to healthcare. It shouldn't be in that position. Thank God for the NHS. Thank God the NHS didn't go the American way.

I see quite a lot of privatisation in my job as a GP - in referrals, in prescribing. GPs' surgeries are increasingly run along privatised lines. It worries me a little bit, but I think the basis of general practice is still intact. The doctor has clinical autonomy, and patients have a say to a large extent. They still have a voice.

A lot of complaints about the NHS are to do with the amount of bureaucracy, which is a mess because of decisions made by this government and previous governments.

There are still inequalities in healthcare. For example, waiting lists - we tell patients that because of the strain on resources they have to wait many months. But then you find other patients who are still somehow getting to the top of the waiting list because they can afford to. I know of patients who can see a consultant privately and still end up high up on an NHS waiting list. In very affluent areas where I've worked that can happen. It's not as equal as it looks.

I don't think there's anything positive to learn from the American system. Too much power lies in the hands of the HMOs and pharmaceutical companies - patients really are afraid and have no voice - and that's something I would not like to see happen here.

I am an NHS doctor, but I am contracted through a company called Chilvers McCrea. It is a private healthcare company and it has taken over 30 practices from the primary care trusts. For doctors, it makes no difference. I think the idea came from UnitedHealth, an American corporation. It started the process in this country. UnitedHealth has now withdrawn, but British companies are still doing it. From a clinician's point of view nothing has changed, but patients are mistrustful about what these companies are after. They have not been around that long.

I think we should be worrying about American influence. It is inching towards the American system. It is a very slow process, but ultimately it will become more and more acceptable. I think it is something we should fear.

'The US system really does have the best, the newest, the most advanced equipment and treatments available'

Mariam Pourshoushtari, 28, American patient

I fear many Americans will react defensively to this film, and British audiences may see this as another excuse to bash America. Personally, I've had good experiences with the US health system. I had meningitis when I was 20 and I happened to be in Minneapolis, which at that time was one of the only places in the world to have a brand-new machine that ended up saving my life. Of course I was maxed out on my insurance within about three weeks, but the government agreed to pick up my bills. I have also had very good experiences on the NHS, but then they didn't have to save my life - they've been involved in the clean-up stuff, as it were. The NHS is on a tightrope. Free healthcare means more British people will go to a doctor when perhaps they don't really need to; GPs are like gatekeepers, they need to asses the motivations of the person in front of them rather than their medical need. The specialists, when you get to see them, are great. As an ideology, universal free healthcare is obviously preferable. But the practicalities mean that the US and British systems are basically equal: medical care can't advance without money, and in a universal system that's always going to be a scarce commodity. As it stands, the NHS is unsustainable - maybe not now but at some stage in the future, it will hit a wall.

Doctors in the US system aren't corrupt or bad. They are still very good doctors trying to help and save lives. The problem is that the insurance companies are trying to tie their hands, trying to get out of paying for the care. But they can only get away with that because the government has pretty much stepped out of healthcare. The huge advantage of an element of privatisation is that it does bring in the money: the US system really does have the best, the newest, the most advanced equipment and treatments available. It's just that that private element has to be properly controlled and regulated, there have to be limits.

'Moore proves something that should be self-evident, that healthcare should be free, and is one of the basic pillars of a decent society'

Nikos Gorgoraptis, 26, junior doctor

In the film, Michael Moore proves something that should be self-evident, that healthcare should be free, and is one of the basic pillars of a decent society. Anything that's not based on that one idea is immoral. These things should be taken for granted but they are not.

What comes through from the film is that there are still some basic public benefits in Europe as opposed to the US, but having worked in this country, and also in France and Greece, I know that things are slowly but steadily changing towards privatisation, and it's really sad. I wouldn't expect a total abolition of public healthcare during my lifetime - at least I hope not. But public healthcare is becoming less good in Europe in general, and even public hospitals are sometimes managed as private enterprises, with medical decisions based on cost, which is not always moral. But we are still nowhere near the image presented by Moore of the US.

'The NHS has got its problems but, my God, it's one of the best things in the world'

Brian Belle-Fortune, 46, student nurse tutor

Before I saw the film, I had kind of thought, "Oh well, America's got this private system, and there's health insurance, and you pay and get treated." But when I saw what it was actually like, I was completely horrified. I was telling my partner about the film when I came home, and she said, "God, you're livid, aren't you?" I kept thinking of that song by Amy Winehouse that begins, "What kind of fuckery is this?" I was thinking that all the way through the film. It's just so wrong. America is supposed to be the world's greatest democracy, but what's happening is completely undemocratic. The NHS has got its problems but, my God, it's one of the best things in the world.

'This film will alert people to the dangers of not cherishing and protecting the NHS from the ruthlessness and the worst excesses of the American system'

Karen Jennings, 54, head of health for Unison

The film really awakens you to what is extraordinary about the NHS, that we have a health system that we do need to cherish and protect. It blew out of the water some of the negative mythology about the NHS. For example, doctors in the US are taught that NHS doctors are not paid very well, and that the system within which they work is not exciting or dynamic. Yet doctors in the UK were interviewed and it is clear that they earned a good income and lived very comfortable lives. At the same time, the British public have a better infant mortality rate, a British person lives longer than the average US citizen, and doctors here are incentivised in terms of things such as public health.

The film brings into perspective what happens when you have a system that is fragmented, that is for profit, in what is really a very flawed market and business environment. It is important for Americans to see what is possible in countries where the systems are based on solidarity, a public sector ethos, and [where people] have principles about these things. It made me feel very proud that Britain was portrayed as a society that cares about the vulnerable.

The global situation around the marketisation of health means there is huge pressure to open up the NHS to provide profits. It is something we should resist as much as possible and this film will alert people to the dangers of not cherishing and protecting the NHS from the ruthlessness and the worst excesses of the American system.

'It does seem illogical to give undue attention to a country where the percentage of GDP spent on health exceeds most others, whereas its outcomes -such as life expectation - are well down the league'

Ian Gilmore, president of the Royal College of Physicians

It is very hard to judge the accuracy of the picture painted of the United States. I suspect there is more than an element of truth in it. Similarly, although the picture of the NHS was rosy, I thought it was reasonably fair - we are proud of the fact that our healthcare is free at the point of delivery.

Certainly there are always concerns about the rising costs of healthcare, and American models have been looked at in order to try to limit costs. But I think that all the models looked at in this country do stick to the principle of being free at the point of delivery, or certainly most of the models do. Some of the models of care that have been looked at do change the way healthcare is delivered quite fundamentally, but they don't move away from that fundamental principle. Our discussions are much more about what should be available on the NHS to everyone, rather than who can afford treatment. Every new form of treatment is scrutinised very closely as to whether it should be available, but availability is not judged solely on cost - it is judged on effectiveness. We haven't got it absolutely right, but the way we look at new healthcare developments, particularly drugs, through the National Institute of Clinical Excellence (Nice), is a model admired across the world.

In my view, undue attention has been paid to some aspects of healthcare policy in the US by UK government in recent years when there are many examples nearer home, within Europe, of alternative models of healthcare. All systems, wherever the funding comes from (taxation, personal insurance, etc) have been struggling with cost containment as technology and, in particular, new drug developments - especially cancer drugs - add to rising expectation and patient knowledge of what is available. It does seem illogical to give undue attention to a country where the percentage of GDP spent on health exceeds most others whereas its outcomes -such as life expectation - are well down the league. That doesn't mean that we shouldn't examine their solutions, but not to the exclusion of those of many other countries that are faring better.
