I live in Belgium. It spends 10.4% of GDP on healthcare. Taxes here are really high generally (and obviously pay for many things other than healthcare).
However, healthcare is excellent. You have to join a mutuelle (a kind of social insurance thing) and it costs around €35 3 times/year for a whole family. You then have a card which you use to see a doctor, get medicines etc. To see a doctor you pay around €25 for a GP, around €35 for a specialist (these are rates outside of Brussels, some doctors charge a lot more - especially in the big cities). You get reimbursed by the mutuelle about €20 for a GP and about €25 for a specialist. Some specialists charge more, but the reimbursement rate is usually fixed (there's a ceiling). To see the ENT with my son yesterday for example, I paid €45 and will only get about €27 reimbursed.
When you get a prescription, the pharmacy automatically does the "reimbursement" part before you pay. So, antibiotics for my child a few weeks ago only cost me €2 in the pharmacy.
You can get an appointment with whatever specialist you like, you don't need a referral. I can easily see a GP the same day. My kids go to a paediatrician, and I can get an appointment with her the same day. Dentists and some specialists like opthalmologists can take a bit longer, maybe a couple of weeks. Scans and blood tests etc are prescribed by a doctor and you can get an appointment to have them done wherever is most convenient. I recently got a breast scan done at a local radiology centre and was given an appointment the same week I called.
Women are followed by the same gynaecologist throughout their pregnancy and he/she delivers the baby in the hospital where they are affiliated. It's fantastic, especially if you have had a history of complications like me. Just like with other specialists, you can pick whoever you want - you call them and get an appointment. No referrals.
Hospitalisation generally costs a little bit, but it depends if you want an individual room or not. The standard mutuelle cover will cover you in a double room and for most costs. However, some hospital groups are more expensive, and many people prefer an individual room. So, for that you would need a hospitalisation insurance to cover the costs. Most Belgian employers provide this for their employees, but if you have to take it out yourself, it costs about €150 per year for the whole family.
I absolutely love the system here. Yes, you pay a little to see a doctor and to get a prescription, but you can get an appointment easily which I think makes it well worth it. Hospital care is amazing - my 3 year old got grommets fitted 2 weeks after the problems being first identified. I have had 4 births, 3 of which were pretty complicated, and my care was second to none, and cost me overall about €150 after my hospitalisation insurance paid their share. One of my kids spent 6 weeks in neonatal intensive care after being born prematurely, and his care cost us absolutely nothing. The bill of €18,900 was settled by the mutuelle and my hospitalisation insurance.
