Techniques for building medical provider databases

A system, comprising:

• a memory configured to store computer-executable instructions;
• and
• a processor in communication with the memory and configured to execute the computer-executable instructions to at least:
• for a plurality of organization entities,
• receive, from a user device operated by an authorized user of an organization entity, information about a plurality of brand entities, a plurality of location entities, and at least one gateway entity, the plurality of brand entities, the plurality of location entities, and the at least one gateway entity associated with respective entity identifiers;
• associate, based at least in part on the information, the plurality of brand entities with the plurality of location entities to create a first set of relationships, the plurality of brand entities being related to each other via the organization entity;
• associate, based at least in part on the information, the plurality of location entities with the at least one gateway entity to generate a second set of relationships, the at least one gateway entity being shared between at least two of the plurality of location entities;
• and
• store the respective entity identifiers, the first set of relationships, and the second set of relationships in a medical provider database;
• generate a search index representing the respective entity identifiers, the first set of relationships, and the second set of relationships stored in the medical provider database;
• configure the search index for searching the medical provider database based on provider name;
• enable a second user device to search the medical provider database, using the search index, for at least one entity of a particular organization entity, a particular brand entity, or a particular location entity;
• and
• enable the second user device to establish a first persistent data connection with a first gateway of a first medical provider identified in the medical provider database and a second persistent data connection with a second gateway of a second medical provider identified in the medical provider database, the at least one gateway entity associated with the first gateway, wherein enabling the second user device to establish the first persistent data connection with the first gateway of the first medical provider comprises enabling the second user device to obtain an access token and a refresh token from an electronic health record system corresponding to the first gateway, wherein the access token and the refresh token are useable by the second user device to establish and maintain the first persistent data connection with the first gateway.
