Immutable-ledger-based workflow management for patient samples

A method performed by at least one hardware processor of a server system, the method comprising:

• receiving a request for a unique sample identifier for a first sample from a first device over at least one network, the first sample associated with patient information,
• in response to the request, generating and sending the generated unique sample identifier to the first device over the at least one network, and for each of a plurality of interactions associated with the first sample:
• receiving interaction information for the interaction from one of a plurality of second devices over the at least one network, wherein the interaction information comprises the unique sample identifier, a user identifier, a location, an event type, and a timestamp, and
• generating a transaction from the interaction information, and record the transaction in an immutable ledger,
• wherein the unique sample identifier and all transactions on the immutable ledger are free of patient information.

A non-transitory computer-readable medium having instructions stored therein, wherein the instructions, when executed by a processor, cause the processor to:

• receive a request for a unique sample identifier for a first sample from a first device over at least one network, the first sample associated with patient information,
• in response to the request, generate and send the generated unique sample identifier to the first device over the at least one network, and
• for each of a plurality of interactions associated with the first sample;
• receive interaction information for the interaction from one of a plurality of second devices over the at least one network, wherein the interaction information comprises the unique sample identifier, a user identifier, a location, an event type, and a timestamp,
• generate a transaction from the interaction information, and record the transaction in an immutable ledger,
• wherein the unique sample identifier and all transactions on the immutable ledger are free of patient information;
• wherein the instructions are further configured to cause the processor to retrieve a history comprising all transactions in the immutable ledger that are associated with a particular unique sample identifier;
• and
• wherein the instructions are further configured to cause the processor to display a representation of the history, along with a digital image of a sample identified by the particular unique sample identifier, within a graphical user interface.
