Abstract

A system and method to manage a quality of delivery of healthcare to a patient. The method includes tracking completion of a portion of a protocol associated with one of a series of candidate hypotheses to deliver healthcare to the patient; tracking a change in a quality of care metric directed to the patient with completion of a portion the protocol, the quality of metric including at least one of a time to rate of reduction in a health risk to the patient and a time to or rate of reduction in symptom or abnormal biometric data of the patient; and outputting an alert in response to the quality of care metric exceeding a threshold.

7. A system to manage delivery of healthcare to a patient, the system comprising:

a controller with a memory in communication with a processor, the memory including program instructions for execution by the processor to;

parse a medical record for a patient, to identify at least one symptom data to compare to at least one keyword in each of a plurality of templates, the at least one keyword associated with a medical condition and a protocol to diagnose or treat the medical condition, each protocol comprising a plurality of tasks to be executed to complete the protocol according to a schedule associated with the protocol;

output a) a plurality of candidate hypothesis each associated with a different templates and b) a confidence level associated with each candidate hypothesis;

automatically output the protocol associated with a selected candidate hypothesis, the outputting to provide a representation of the protocol via an output device;

track completion of a portion of the protocol associated with the selected candidate hypotheses to deliver healthcare to the patient, wherein tracking completion of the portion of the protocol includes tracking completion of tasks executed according to the schedule associated with the protocol;

track a change in a quality of care metric directed to the patient with completion of the portion the protocol, the quality of care metric including at least one of a) a time to rate of reduction in a health risk to the patient and b) a time to or rate of reduction in symptom or abnormal biometric data of the patient;

output an alert in response to the quality of care metric exceeding a threshold; and

decrease confidence in the selected candidate hypothesis and increasing confidence in one or more of the other plurality of candidate hypotheses triggered by acquiring the at least one quality of care metric exceeding the threshold.

8. The system of claim 7, the controller further operable to:

decrease confidence in the selected candidate hypothesis and increasing confidence in one or more of the other plurality of candidate hypotheses triggered by acquiring the at least one quality of care metric exceeding the threshold.
