Another trend that I know of in the Netherlands (where I'm from) is that newly built hospitals have private rooms for all patients. These hospitals no longer have shared rooms by design. They also try to minimize hospital stays as being in a hospital exposes you to hospital infections, is expensive, and to be avoided unless explicitly needed.
That's a big difference with Germany, which is old fashioned on this front. The default attitude in Germany seems to be to keep people in a hospital much longer. In Germany you only get a private room if you need it medically or if you take private insurance.
I suspect a lot of this stuff is part cultural and part wrongly aligned incentives because hospitals just bill whatever to insurers and couldn't care less about patient comfort because their paying customer is the insurer, not the patient. The insurer cares about cost, the hospital cares about milking the insurer to the maximum of their ability. Between those two, patient comfort is not much of a concern.
The reason things have improved in the Netherlands is that they spent the last decade realigning incentives to cut cost between insurers and hospitals. People pick their own insurer (they are all private). However, all insurers are required to offer the same base packages (with extras if you want). So, people can easily switch insurance provider if they want and they do. So, insurers now compete on quality of service and cost. Which is why a lot of hospitals are actively concerning them selves with upgrading their facilities to improve customer happiness (still the insurers). Insurers are happy when their customers don't switch to another insurer and when hospitals don't waste their money.
