Abstract: A system for assisting the exchange of information between healthcare providers, third party payors and persons receiving healthcare, employs an electronic data index with a record for each person identified listing the payors and/or providers with data regarding that person and instructions for accessing these data. The index records are established and may be accessed through a hash function based on covered persons' names and further identification such as birthdates. Authorized Requestors seeking information with regard to a covered person enter the person's name and further identifying information into a hash value generator in order to create the identifying hash function. A hash table identifies the location of the index record related to that individual in the data index. The index record identifies payors and providers with data on the person associated with the index record. The index record also contains instructions for accessing these files from the payors and providers.

Abstract: A system for registering, tracking the medical process, and servicing persons who do not have healthcare insurance employs a central database available to healthcare providers, employers, and the public. The system provides a number of unique advantages to healthcare providers and employers to register their uninsured patients, employees and retirees and to individuals who voluntarily register. These benefits motivate the registration of uninsured persons into the system. The registration involves a consent form and a registration form which establishes the initial information for a patient in a central database. Each patient is assigned a unique identifier number and changes in healthcare status, treatment and the like are entered into the system to track the medical progress of uninsured persons who are registered. A variety of services such as specialist referrals, medical checkup reminders and the like maintain the system in active contact with all the registered uninsured.
