I am reading a few patient notes and see 2/2 used several times, e.g.:

  • Unclear if 2/2 to aspiration
  • Recurrent UTIs and hosp. for urosepsis - thought 2/2 to chronic indwelling Foley catheter for neurogenic bladder.
  • Trach was placed because was unable to clear secretions on her own 2/2 to respiratory weakness
  • Her decreased responsiveness was thought to be 2/2 to meningitis
  • pt has respiratory weakeness 2/2 to multiple sclerosis

What does 2/2 mean in a patient note?

Right Diagnoses. Com

It means secondary to.

From your question:

Patient has respiratory weakness secondary to multiple sclerosis

If you are looking for a more credible source, this site mentions that it means "secondary to."

Meded.uscd.edu also mentions its meaning.

    Thanks! 2/2 to is therefore a RAS syndrome. Mar 27, 2016 at 21:17
  • @FranckDernoncourt True! Maybe I should add that to the answer. It seems to add something.
