Abstract

A method, system and computer-readable medium are provided for determining compliance with one or more patient care rules and protocols, the method including the steps of sending infusion information from a pump to a processor pertaining to one or more drugs provided to a patient, sending ventilation information from a ventilator to the processor pertaining to ventilation provided to the patient and determining, with the processor, a variation between actual care of the patient and a set of rules and protocols associated with care of the patient at least in part based on the infusion information and the ventilation information.

First claim

What is claimed is:

1. A method comprising:
administering, by an infusion pump, one or more drugs to a patient, the one or more drugs including at least one of a sedative drug and a pain therapy drug;
receiving, from the infusion pump by a processor without user interaction, infusion information pertaining to one or more drugs being administered to the patient by the infusion pump;
receiving, while the infusion pump is administering the one or more drugs to the patient, from a ventilator by the processor without user interaction, ventilation information pertaining to ventilation being provided to the patient by the ventilator;
reducing a dosage of at least one of the one or more drugs administered to the patient;
determining, in real time by the processor, based on the reduction of the dosage, a spontaneous awakening trial (“SAT”) comprising a first period of time in which the ventilation is provided while the dosage of the one or more drugs administered to the patient by the infusion pump is reduced or stopped;
changing an operation mode of the ventilator while the ventilator is providing the ventilation to the patient and the one or more drugs are being administered to the patient to initiate a spontaneous breathing trial (“SBT”) comprising a second period of time in which the ventilation provided to the patient is adjusted;
determining, in real time by the processor, based on the change of the operation mode of the ventilator, that the SBT occurred;
detecting, in real time by the processor, that the dosage reduced or stopped while the one or more drugs are being administered to the patient, and the change to the operation mode of the ventilator while the patient is being ventilated;
generating, based on detecting that the dosage reduced or stopped, a first plurality of markers indicating a start and a termination of the SAT;
generating, based on detecting the change to the operation mode, a second plurality of markers indicating a start and a termination of the SBT;
accessing, from a hospital network including a hospital information system, a set of rules and protocols associated with care of the patient;
determining, in real time by the processor based on the ventilation information and the infusion information, a variation between actual care of the patient, including the one or more drugs administered to the patient and the ventilation provided to the patient, and the set of rules and protocols associated with care of the patient;
determining, in real time by the processor, based on the generated first or second plurality of markers and determining the variation, a first indication of whether to initiate termination of the ventilation and a timing for performing an extubation of the patient ventilation;
providing, by the processor, to a client device associated with a care provider in real time responsive to determining the first indication, the first indication of whether to initiate termination of the ventilation and the timing for performing the extubation;
terminating the ventilation of the patient;
determining whether the ventilation was terminated for a threshold period of time;
responsive to the ventilation being terminated for a threshold period of time:
determining that the extubation of the patient was performed;
determining whether the timing of the extubation of the patient was performed according to the rules and protocols;
recording an extubation marker representative of the extubation; and
providing, to the client device for display at the client device, a warning notification responsive to determining the variation, and a notification of whether the timing of the extubation was performed according to the rules and procedures,

wherein the client device is remotely connected to the infusion pump and the ventilator over a network.

2. The method of claim 1 , further comprising:
in response to determining that the SAT has occurred, determining a start time and a stop time of the SAT based at least in part on one or more of the infusion information and ventilation information.

3. The method of claim 1 , further comprising:
in response to determining that the SAT has occurred, comparing a frequency of the SAT to a preferred frequency of SATs defined by the set of rules and protocols.

4. The method of claim 1 , further comprising:
in response to determining that the SAT has occurred, determining whether each of the SAT were successful based on a duration of the SAT, wherein the duration of the SAT is determined based on a start time and a stop time of the SAT.

5. The method of claim 1 , further comprising:
in response to determining that the SBT has occurred, determining a start time and a stop time of the SBT based at least in part on
one or more of the infusion information and ventilation information.

6. The method of claim 1 , further comprising:
in response to determining that the SBT has occurred, determining whether each of the SBT was successful based on a duration of the SBT, wherein the duration of the SBT is determined based on a start time and a stop time of the SBT.

7. The method of claim 1 , further comprising:
in response to determining that the SBT has occurred, identifying one or more preceding events that occurred previous to the SBT and comparing the one more preceding events to one or more preferred preceding events defined by the set of rules and protocols.

8. The method of claim 1 , further comprising:
in response to determining that the extubation was performed, identifying one or more preceding events that occurred previous to the extubation and comparing the one or more preceding events to one or more preferred preceding events defined by the set of rules and protocols.

9. The method of claim 1 , further comprising:
receiving patient vital signs indicating vital conditions of the patient from one or more of a laboratory system, a monitor, or dispensing system by the processor; and wherein determining the variation is further based on the patient vital signs.

10. The method of claim 1 , further comprising:
receiving ADT information including one or more of demographic information and state information for the patient from a hospital information system by the processor; and wherein determining the variation is further based on the ADT information.

11. The method of claim 1 , further comprising the steps of:
receiving information from at least one of a laboratory system, dispensing system or a monitor by the processor, and wherein the determination of the variation is further based, at least in part, on the information from the at least one of the laboratory system, dispensing system or the monitor.

12. The method of claim 1 , wherein the infusion information includes one or more of a drug type for each drug administered to the patient, a dosage of each drug administered to the patient, a rate of each drug administered to the patient, or an indication of infusion started or stopped.

13. The method of claim 1 , wherein the ventilation information includes one or more of a respiratory rate, tidal volume, amount of oxygen, amount of peek respiratory pressure, or alarms triggered at the ventilator.

14. The method of claim 1 , further comprising the steps of:
calculating a weight based dosage of each drug administered to the patient by the infusion pump based at least in part on the infusion information and a weight of the patient provided by an information system, wherein the set of rules and protocols includes a preferred dosage for each drug administered to the patient; and
comparing the weight based dosage of each drug to the preferred dosage for the dru
