Decided I wanted to try to help everyone out, unless you want to be immediately spoiled for the answers here's how I finally got it. While you talk to your patients before getting access to the key, pay attention to their side effects like "migraine" or "lack of sleep" since those are usually the keywords, also check out the documents/papers that go with the key because usually that's also where the keywords will be stored. After you insert one of the keywords, you need to click and press space to drag the torn piece of documents together, you don't need to piece the entire document, just the headline and you don't need to input the entire headline, just the treatment it recommends. Your score will also be affected by the choices you make early on before you decipher the keywords so make sure to play along and be amiable! I finally got a score of 100 and added it to 112% but I'm very unsure about this...
Below is the cheat sheet for everyone.
Simba:
For the keyword it's "concussion" and when you see the top of the article the sign off should be "collaborative care"
Socco:
For the keyword it's "migraine" and the sign off should be "meditation"
Summer and Autumn:
For the keyword it's any of the following "sore throat, cough, and high fever" and the sign off should be "rest" (I want to thank lina for this, like I struggled a lot with this one)
Beet:
Keyword should be "insomnia" and the sign off should be "aromatherapy"
Oreo:
Keyword should be "chf" and the sign off should be "oxygen therapies" (Actually here, I am so confused because in the article it states that it should be "energy therapies" so what is it really???)
This was the culmination of MULTIPLE playthroughs and help from the comment section...
