Which matching rule criteria is recommended for unifying profiles without risking exposure to personally identifying information?

  1. Email address and phone

  2. Party Identification on Patient ID

  3. Fuzzy first name, exact last name, and email

  4. Exact last name and email

The correct answer is: Party Identification on Patient ID

The recommended matching rule criteria for unifying profiles while minimizing the risk of exposing personally identifying information is based on "Party Identification on Patient ID." This approach focuses on using a unique identifier that is typically assigned within a healthcare context, such as a Patient ID. This unique identifier is not inherently personal in nature and does not reveal sensitive information about an individual, making it a safer choice for matching purposes. By utilizing a standardized identifier, it facilitates the consolidation of profiles without risking the exposure of sensitive personal details. This is especially important in sectors like healthcare, where privacy regulations are strict and protecting individuals' identities is paramount. In contrast, the other options involve more direct personal identifiers, such as email addresses, phone numbers, or names, which could potentially lead to breaches of privacy if mismanaged or exposed. Thus, using a method like Party Identification on Patient ID effectively balances the need for accurate matching with the necessity of protecting personal information.
