Personal iPad

For my personal life, I use a digital planner on my iPad for my calendar, to do lists, etc. At work, I currently use a paper planner (I’m a dialysis floor nurse and clinical nurse manager). Sometimes a patients name or minimal other identifying information makes its way into my to do lists: “Call Smith’s PCP about appointment” or “Jones plan of care due today” etc. Right now I shred my todo lists when they’re completed. Id like to switch to using a digital planner for work too but I’m concerned if this would be a HIPAA violation. Perhaps I could use patient initials instead of names but that might be challenging. Of course my iPad is locked but the security level might not be up to HIPAA standards. I would erase any identifying information once I was done with it and it would be pretty limited (certainly no patient charts or anything, just my personal notes). What do y’all think?
