Notice how all those relate back to not caring about the fact that someone is suffering? Cruelty in itself can be simply not caring that someone is suffering. The people themselves might've cared, but the -methods-, also called the treatment itself, was desgined without care for her suffering. So yes, the treatment was inhumane.
The treatments aren't designed without care for her suffering, they are general methods that are used in most situations. The problem in the situation is that Chris does not know that all of it is natural (she does not know how isolation works and modern medical methods aren't known in her previous world). However, perception does not come into play in being inhumane in this situation. Being inhumane is inhumane regardless of the perception of the one it is being done to (enjoying being tortured is inhumane even if you enjoy being tortured and chemotherapy is still humane even if it hurts a lot) as inhumane is a doer's description and not a receiver's.
And you're right I can't find where they specifically were told not to talk to her, however they still don't talk enough to pass for real human interaction. That also doesn't change that they kept her out of the loop of her friend at first, which has no relation to medical protocol.
Medical protocol states that you can't divulge patient data to someone not of kin or the legal guardian. Kanji was a patient at the time and Chris is neither her kin nor her guardian. This is basic hospital procedure.
There's the fact that they didn't provide any entertainment for her,
Which we did not see, they did not know what her ideas about is and can't use world knowledge to supplement.
PS. You can't argue for something that was never shown in the first place.
then they even still shrunk her room later to just her bed and cough in chapter 30. They had plenty of space to let her roam her room, but they chose to take that away for some arbitrary reason.
Yes, this is stupid, but stupid =/= inhumane. Medical isolation can happen, curtains in isolation rooms, I doubt.
Also on day 10, she had more than 10 not healed needle wounds.
Obviously needle wounds don't instantly heal. Now Chris could've used healing magic but that's her choice, and sticking needles isn't inhumane (the sites where they sampled blood isn't right, you don't stick it in the middle of the forearm. Sites where you sample blood are places where it is easy to do so which is why the most common sites are the middle of the arm, the wrist, the finger and between the back of the knee). Having multiple sites for blood sampling is normal as using the same site multiple times could damage the vein/artery permanently. Again not inhumane.
There is also in chapter 20 evidence that they don't even properly inform her of preparation of test. Telling her when it's dinner time that she can't eat because of a upcoming test.
Doing a glucose test in the morning is the best time to do it as you only skip one meal (dinner). Them telling it at dinner is convenient in the situation, because she is a stay in patient and this is the time when it is told about it. Now the problem here is that in a normal patient, they would've known from the onset all of the tests to be done to her, which is not possible in her situation. None of these are inhumane still.
When she didn't eat from clear depression, their response was "You need to eat cause there will likely be more test" They didn't actually bother to change anything until Chris got violent, and that was probably the heads up just being afraid she'd escape with magic. There is no way that's 'humane'.
"You need to eat" is a common response to patient. You need to know that basic actions for certain situations are predetermined in hospitals. They didn't change anything because protocol, and the protocol is designed humanely. Had Chris known the complete nuance of the situation then our vantage point would change and we wouldn't have this inhumane nonsense, which goes back to my earlier statement. That being humane does not change regardless of the perspective.
