Abstract

Embodiments of systems and methods for providing protocols for administering an aspect of care are presented. Specifically, certain embodiments relate to a sepsis diagnosis and management protocol which may have been segmented according to the severity of the sepsis, where the care directives provided by the differing segments of the protocol will be of differing intensity or invasiveness based upon the severity of the patient'"'"'s disease. Embodiments of such protocols may be implemented in conjunction with computer systems to aid in providing that aspect of care in conjunction with a particular patient.

Claims

1. A system for computerized implementation of a protocol for diagnosis and management of sepsis, comprising:

one or more presentation devices configured to present interfaces;

a protocol system coupled to the one or more presentation devices, comprising;

a processor;

a data store;

a computer readable medium comprising instructions executable by the processor for;

implementing a replicable protocol for the diagnosis and management of sepsis comprising a first segment including a first set of rules corresponding to sepsis and a second segment including a second set of rules corresponding to severe sepsis, wherein the second set of rules are further segmented into a fluid/blood therapy segment, a vasopressor/inotrope therapy segment, an adrenal insufficiency/steroid therapy segment and a pulmonary artery catheter directed therapy segment; and

implementing the protocol comprises;

executing an instance of the protocol by a protocol execution module;

determining a first rule of the protocol by the protocol execution module;

presenting one or more interfaces corresponding to the first rule through a first presentation device, wherein the one or more interfaces comprises at least one request to obtain data corresponding to a patient;

receiving the data associated with the first rule as implemented by a practitioner and corresponding to the patient at the protocol execution module from the first presentation device using the one or more interfaces;

storing the data corresponding to the patient and associating the stored data with the instance of the protocol; and

determining a second rule of the protocol based on the stored data corresponding to the patient and the instance of the protocol, wherein the second rule is determined by the protocol execution module.

2. The system of claim 1, wherein the first set of rules comprising the first segment comprises one or more rules for detecting sepsis.

3. The system of claim 2, wherein the one or more rules are configured to generate a score based on a heart rate, temperature, respiration rate and white blood cell count.

4. The system of claim 1, wherein the data corresponding to the patient is received from a medical device coupled to the patient and the protocol system.

5. A non-transitory computer readable medium comprising computer executable instructions, which when executed are configured to implement a protocol execution module of a protocol execution system, the protocol execution system coupled to at least one presentation device, the protocol execution module configured to:

execute an instance of a replicable protocol for the diagnosis and management of sepsis, wherein the protocol comprises a first segment including a first set of rules corresponding to sepsis and a second segment including a second set of rules corresponding to severe sepsis, wherein the second set of rules are further segmented into a fluid/blood therapy segment, a vasopressor/inotrope therapy segment, an adrenal insufficiency/steroid therapy segment and a pulmonary artery catheter directed therapy segment;

determine a first rule of the protocol;

present one or more interfaces corresponding to the first rule through a first presentation device, wherein the one or more interfaces comprises at least one request to obtain data corresponding to a patient;

receive the data associated with the first rule as implemented by a practitioner and corresponding to the patient from the first presentation device using the one or more interfaces;

store the data corresponding to the patient and associating the stored data with the instance of the protocol; and

determine a second rule of the protocol based on the stored data corresponding to the patient and the instance of the protocol.

6. The computer readable medium of claim 5, wherein the first set of rules comprising the first segment comprises one or more rules for detecting sepsis.

7. The computer readable medium of claim 6, wherein the one or more rules are configured to generate a score based on a heart rate, temperature, respiration rate and white blood cell count.

8. The computer readable medium of claim 7, wherein the data is received from a medical device coupled to the patient and the protocol system.

9. A method implemented in a protocol execution module of a protocol execution system, comprising:

determining, at a protocol system including a processor, a first rule of a replicable protocol for the diagnosis and management of sepsis;

wherein the protocol comprises a first segment including a first set of rules corresponding to sepsis and a second segment including a second set of rules corresponding to severe sepsis, wherein the second set of rules are further segmented into a fluid/blood therapy segment, a vasopressor/inotrope therapy segment, an adrenal insufficiency/steroid therapy segment and a pulmonary artery catheter directed therapy segment;

presenting one or more interfaces corresponding to the first rule through a first presentation device, wherein the one or more interfaces comprises at least one request to obtain data corresponding to a patient;

receiving the data associated with the first rule as implemented by a practitioner and corresponding to the patient from the first presentation device using the one or more interfaces;

storing the data corresponding to the patient and associating the stored data with the instance of the protocol; and

determining, at the protocol system including the processor, a second rule of the protocol based on the stored data corresponding to the patient and the instance of the protocol.

10. The method of claim 9, wherein the first set of rules comprising the first segment comprises one or more rules for detecting sepsis.

11. The method of claim 10, wherein the one or more rules are configured to generate a score based on a heart rate, temperature, respiration rate and white blood cell count.

12. The method of claim 11, wherein the data is received from a medical device coupled to the patient and the protocol system.
