Important Considerations

Patient Creation: If your application uses the Patient CREATE resource, the API will allow the creation of new patient records. Be mindful of avoiding duplicate entries for patients already in the system.
Patient Matching: To minimize duplicate patient records, ensure that your application at least matches on the following key identifiers:
- First name
- Last name
- Date of birth (DOB)
- Gender
  Additional recommended matching criteria include:
- Email address
- Phone number
- Zip code
- Social Security Number (SSN) (if applicable)
