The reason for the question is that several years ago there was a new treatment for macular degeneration. In Holland the waiting list was six months long to get that treatment. People went blind waiting and waiting. It turns out that there wern't enough qualified doctors. People who could afford it went to CH where the serum was made (with pigs blood from Holland) and got treated.
Does Belgium have a limit on the number of doctors in any speciality?
Degeneration and by extense (macular) degeneration is rather 'common'. It is an example that is like many things in medicine mind-boggling. It is I think something revolting that one has to live with 'general' degeneration, in fact even the fact of aging is on a cellular base and genetically regulated, there are cells identified that are active in this process of ageing, so one could say that ageing (degeneration) is also evolution and development. Macular degeneration is a terrible thing, slowly losing the view must be a very frustrating process. In general, there are a few forms of macular degeration that are indeed hard to treat, but in most cases there is some treatment that "restaures" to a certain level the view, for example, "one can read again" (which is for me one of the essentials in my life, I don't underestimate the fact that seeing shapes and colours can be most enjoyable, but I fear the eventual day that I will lose the capacity of reading.) These often laser, retina and 'fluid' treatments can be done rather quickly in Belgium.
But you point out some extremely interesting, actual and one of the important future concerns in Medicine. You don't use the word for it, but I think that you're implying "gen" treatments. These are, if you look at if from a certain distance and as an 'amateur' like me, rather "new" in medicine. I remember the big worldnews of the 'complete mapping of the human gen' as if it were yesterday. I think that since the nineties, lots of scientist could focus their attention on looking for this type of gen-treatments in lots of areas of medecine. And as you know, before a type of medication is officially admitted, it takes a tremendous lot of time, it sometimes (often ?) takes more time to get them 'legalized' and accepted for reimbursement in 'public health service' and other authorities, than the design, development and the testing together. And Switzerland is from what I see the epicentre of development of really sophisticated and effective drugs and medication. And that, dear OXY60, together with the fact that it takes for governments years to give a 'green' light to the latest newest medication, brings us back to the remark I made in my first reply 'the one that has the money is more likely to get the best treatment'.
Now an answer to your question, in short.
Here in Belgium, government and authorities try to regulate the numbers of doctors, not only in comparison to density of inhabitants per region, but also per discipline.
I heard of for example a lack of psychiatrists in Holland, in particalur 'youth' psychiatrists. But this particular lack for instance has a strong link with politics and social organisation. One could also state that this lack is mainly a concern to look for solutions for the phenomenon of an increasing number of youngsters that don't go to school, hang around and finally (could) become 'criminals' or a burden in the eye. It could even be seen positively in the sense that it has probably no sense at all to put youngsters for a long time in jail.
Another parameter in neighbourn countrys is the 'emigration'. Dutch doctors, psychiatrists, dentists etcetera earn more money than in Belgium. So, a lot of doctors leave Belgium and start practicing in Holland.
But, a very strange thing is the 'maximum' of student-doctors that are allowed to... go from the first grade in University to the second ! Imagine, you study a year medicine, you're brilliant, feel good and than, for no reason at all except some kind of lottery, you're not allowed to continue ! That must really be horrible except for those who can see life as purely a hobby (which it probably is, but to some extend).
And finally, dear OXY60, one of the biggest challenges is probably the future lack of nurses and 'aids' in order to maintain a certain standard and comfort of life for the population growing much older, and not much births.
Kind greetings.
