Great Question.
First. 10 years is a very long time to not visit your health care provider. They should be reviewing labs, immunizations, exams at least every 1-2 yrs. Protocols change and when something needs to be done may very well change if better evidence is available.
Second. I would encourage you to have a Medical/Dental record that you review at least annually. It should have all of your previous illnesses, surgeries, allergies etc., along with dates, who did it and possibly why it was done. When you see your primary care they will ask for this info. Always good to have it up to date, you never know when an emergency will occur.
BONUS TIP. ask family and relatives for any disease history. You may find it interesting to know that for example, your Paternal grandfather had a heart attack at 50, your dad had a heart attack at 51, and you are 40. The doctor might treat you differently based on your family’s cardiovascular disease history. If you wait to find out when filling out the form, you may forget. It could be an interesting holiday dinner conversation.
Third. You need to use a system that is secure and has reminders for this information. Personally, I use Evernote for just this type of material. I can scan anything in and set a reminder for when to review it. When I’m at the doctor’s office, it is easily retrievable. This could go into a 1Password, or another secure platform if you are more concerned, but they don’t have active reminders for review. Scrolling through a calendar for your tonsillectomy and your vasectomy could take a while. A calendar reminder to review “medical in 1Password” or a 6-month to-do list would also be fine.
Forth. If it is a multiple-step project (i.e. GTD terms) consider making it a project and moving it out to when you want to start working on it. A passport renewal should not a have due date for when it expires. About 6 months out you could start the project for “New Passport”. What forms, what is required, How much, new cool photo, etc. Any good project management should work here.
I do this with my credit cards, driver’s license, passports, Nursing license, vehicle registration, home warranty expiration etc. all into Evernote.
I hope this helps.
