Description

I am trying to deidentify healthcare data similar to how MIMIC prepared its data. Is the algorithm that randomly shifts dates and deidentifies DOB of those aged 89 or greater available?

No it's not available, but it's not complicated. It's a random offset from a fixed point of time in the patient's stay.

We no longer deidentify DOB per se (it was confusing for a lot of past users). Instead, we provide the age at their first hospital admission (roughly) and if an age is > 89, we set it to 90.

TY for the quick response. I was looking to borrow a shortcut, but I will implement my own. You are right it is not complicated.

Just be sure to use a cryptographically secure shift, and don't roll your own! Good luck!
