Methods and apparatus for procedure tracking

A method of quantifying healthcare agent interaction during a healthcare procedure with a self-verifying array of nodes, the method comprising:

• a) discovering with the self-verifying array of nodes at least a first node, a second node, and a third node, wherein each node of the self-verifying array of nodes comprises at least a respective processor, a respective digital storage and a respective wireless transceiver;
• b) assigning a respective unique identifier to each of the first node, the second node, and the third node when they are discovered;
• c) establishing communication between the first node and at least the second node and third node in the self-verifying array of nodes, wherein each of the first node, the second node and the third node generate at least a first set of values from the communication;
• d) utilizing the first set of values to determine a relative position amongst at least the first node, the second node and the third node;
• e) removably attaching the first node to a first healthcare agent, and the second node to a second healthcare agent, wherein the first node remains attached to the first healthcare agent and the second node remains attached to the second healthcare agent during a time of the healthcare procedure;
• f) attaching the third node to a reference position in a healthcare facility resource, wherein the third node is in the reference position in the healthcare facility resource during the time of the healthcare procedure;
• g) wirelessly communicating between the first node, the second node, and the third node during the time of the healthcare procedure;
• h) verifying a presence of at least one of the first node, the second node and the third node in the self-verifying array of nodes during the time of the healthcare procedure;
• i) storing, in the respective digital storage of at least one of the first node, the second node, and the third node the generated values for communication variables and unique identifiers for the first node;
• the second node and the third node;
• j) with the respective processor of at least one of the first node, the second node, and the third node, generating a respective set of position coordinates indicative of a position of each of the first healthcare agent;
• and the second healthcare agent, each respective set of position coordinates based upon values included in an aggregate of values for the communication variables received into the respective processor;
• and
• k) with the respective processor of at least one of the first node, the second node, and the third node, generating an orientation of one or both of the first healthcare agent and the second healthcare agent.
