People are sometimes shocked to realize how much personal data can be sustained in master patient indexes-such as marital status and problematic payment histories or cancellations.

Do you believe the advantages of master patient indexes outweigh disadvantages, or have medical records gone too far in documenting and sharing private information? Describe your reasons.
