If an alert is not warranted then at step 219 the data is routed to a web site for instantaneous presentation upon authorized access by either the patient, a proxy or a healthcare professional. If an alert is warranted, then at step 221 a formatting process is implemented, and at step 225 a signal is sent to web-site 231 notification routine causing a non-secure alert signal 240 to be transmitted in a push fashion according to pre-set protocol to healthcare providers.

For example, a healthcare system could compare device failure or malfunction rates within its healtlicare system to population statistics to determine quality of device implantation and follow up. Alternatively, a healthcare system could compare the physiology or complications from its patients to population statistics.
  • Healthcare systems could predict utilization of their services by evaluating complication rates within large populations of patients and extrapolating that data to their own population. Many other valuable types of information can be envisioned, and particularly when using high relevance and rapidly accessible high volume data/information which is nowhere else found. In return for this exceptionally miique information, the healthcare system would pay a fee to entity 715. These fees could be structured in a variety of ways depending on the type of information, frequency of interaction and depth of richness and utility of information. Potential mechanisms include time based subscriptions, single use access fees, and multiple versions. Invoicing, billing and payment could be carried out as well through a variety of mechanisms, including direct computer-to-computer transfer, credit card billing, paper invoicing and checks, or any of the multitude of ways of billing and collecting in business.
