Your health is scattered across too many places.

Every visit, prescription, and lab order lives somewhere else. These are the questions DATEM answers for you.

  1. Where did the cardiologist's prescription end up?

    One in a wallet, one in a photo, another lost in an email.

    Modules that address this:
    • Visits & Consultations
    • Lab Orders & Studies
    • Attachments
  2. What did the other doctor prescribe?

    Each specialist only sees their isolated piece of your story.

    Modules that address this:
    • Medications
    • Prescription History
    • Doctor Directory
  3. How long has your blood pressure been like this?

    Memory doesn't retain numbers; your records do.

    Modules that address this:
    • Vital Signs & MAP
    • OMRON & FreeStyle Import
    • Trends & Reports
  4. On a scale of 1 to 10, how bad is the pain?

    Describing symptoms is exhausting when you already feel unwell.

    Modules that address this:
    • Symptoms (NRS Scale)
    • Bristol Stool Scale
    • Nutrition
  5. Any allergies? Family medical history?

    The exact same questions, answered from memory at every single appointment.

    Modules that address this:
    • Conditions & Allergies
    • Surgeries & Family History
    • Vaccines
  6. Do you have your insurance policy number handy?

    In an emergency, nobody recalls insurance details from memory.

    Modules that address this:
    • Health Affiliations & Insurance
    • Phone Directory
  7. Is mom due for her vaccine? What about the dog's deworming?

    Caregiving also means keeping track of the people and pets you love.

    Modules that address this:
    • Family & Pet ProfilesPro
    • Vaccines & Deworming

Your health shouldn't be a puzzle. DATEM connects the pieces.
