About One Medical Passport

Completing a One Medical Passport medical history online is easy. For most patients, filling out the entire questionnaire takes less than 30 minutes. Please fill out the questionnaire accurately, and be assured that all your information is kept confidential and will be thoroughly reviewed by your medical team. At any time, you can quit filling out the questionnaire and come back and complete the unfinished portion at a more convenient time.

One Medical Passport is a website that allows you to enter your information at any time from anywhere. You can also print out a copy of your medical history after you create it online and keep it with you or with your other healthcare documents, as well as have access to it online anytime you need it or want to update it.

Information Security: One Medical Passport uses the highest grade of Internet security available: 128 bit encryption with SSL (secure socket layer) technology. Your information is stored on servers at a secure web hosting site and will only be released to your medical team. Your information is never released to anyone other than your medical team.
