This game was going great until I got to this point. Why did the dev even include this level? You can't walk two steps without getting disorientated, and the cops or doctors always catch me no matter where I go. How the hell do you beat this level?

This level was pretty frustrating for me too. Pay attention to the cops' animation to tell when to move past them, and just time the doctors movements to get past them. Nothing can be done about the disorientation, AFAIK.

This might be the information I needed, as I hadn't even noticed them changing. Thanks, I'll try it later.

Also, as a side note to anyone else stuck on this level, I checked my chapters again and noticed that the next chapter, "Assault" is now unlocked even though I didn't actually complete "Trauma." Maybe the devs realized some people might just want to skip the hospital level.

Not sure how helpful this will be, but there does not seem to be a pattern to this state of disorientation, suffice to say that you can tell when it is close by how bright and fuzzy the screen begins to get before the state sets in, so if there was any advice I have to offer, if you are in a "safe" room, and the screen is bright and fuzzy, trigger the state where no one can catch you, and that should give you a window, even if a small one, to make a break for another safe room, before another state of disorientation sets in.

In response to the side note, I've actually encountered unlocked chapters without completion of the prerequisite chapter before trauma and assault, with a bit more testing, I found the unlocking of a chapter seemed more frequent when quitting a prerequisite chapter during the chapter intro, it could be different for others, however.

I think it increases as you walk, and decreases as you stand still. I've tried taking smaller, shorter walks and found that the disorientation doesn't set in as quickly.

I don't believe I was stationary long enough to notice the decreases, I sort of sped through that chapter. Thanks for the observation, I guess I complicated it a tad more than I needed to.
