Abstract

Various systems and devices are provided for determining a weaning readiness for weaning a patient from a thermoregulated microenvironment. In one example, a method includes receiving current patient parameters of the patient and applying a weaning model to the current patient parameters to calculate a weaning index representing a likelihood that the patient can be successfully weaned from the microenvironment. The method also includes outputting the weaning index for display on a display device or for storage in a medical record of the patient and upon outputting the weaning index, receiving one or more subsequent patient outcomes, the one or more subsequent patient outcomes comprising whether the patient developed any complications within the duration since being weaned from the microenvironment. The method also includes updating the weaning model based on the one or more received subsequent patient outcomes.

Claims (18)

1. A method, comprising:

obtaining a plurality of current patient parameters of the patient in response to a request to calculate a weaning index for a patient housed in a thermoregulated environment;

sending the plurality of current patient parameters to a weaning assistant configured to calculate the weaning index based on the plurality of current patient parameters and historical data for a plurality of prior patients previously housed in a thermoregulated microenvironment;

receiving the weaning index from the weaning assistant;

displaying the weaning index on a display device;

upon displaying the weaning index, receiving one or more subsequent patient outcomes, the one or more subsequent patient outcomes including whether the patient was readmitted to the microenvironment within a duration since being weaned from the microenvironment, whether the patient developed any complications within the duration since being weaned from the microenvironment, or ambient conditions when the patient was weaned from the microenvironment; and

providing the one or more subsequent patient outcomes to the weaning assistant for updating a weaning model based on the one or more received subsequent patient outcomes,

wherein the request to calculate the weaning index is generated upon completion of a weaning protocol, and wherein the weaning protocol gradually reduces a temperature of the microenvironment until the temperature reaches ambient temperature.

2. The method of claim 1 , wherein upon displaying the weaning index, the method further comprises receiving an indication of patient weaning status and sending a notification of the patient weaning status to the weaning assistant.

3. The method of claim 2 , wherein receiving the indication of the patient weaning status comprises receiving a first indication that the patient is currently being weaned or a second indication that the patient is not currently being weaned, the first indication or second indication received via user input and/or via signals output from the microenvironment, the notification usable by the weaning assistant to update future weaning index calculations.

4. The method of claim 1 , further comprising upon displaying the weaning index, sending one or more notifications of subsequent patient outcomes to the weaning assistant, the one or more notifications usable by the weaning assistant to update future weaning index calculations.

5. The method of claim 1 , wherein the plurality of current patient parameters comprises a first plurality of current patient parameters, and further comprising performing the weaning protocol by:

obtaining a first comfort index of the patient by obtaining a second plurality of current patient parameters while the thermoregulated microenvironment is at the reduced temperature and sending the second plurality of current patient parameters to the weaning assistant, the weaning assistant configured to calculate the first comfort index for the patient based on the second plurality of current patient parameters and the historical data;

responsive to the first comfort index being above a threshold, iteratively reducing the temperature of the thermoregulated microenvironment and obtaining an additional comfort index each time the temperature of the thermoregulated microenvironment is reduced; and

once the temperature of the thermoregulated microenvironment is at the ambient temperature, generating the request to calculate the weaning index.

6. The method of claim 5 , wherein the first plurality of current patient parameters comprise a respiration rate of the patient, a heart rate of the patient, a temperature of the patient, a gestational age of the patient, a number of days since birth of the patient, and/or an oral sucking reflex of the patient each obtained at a first point in time.

7. The method of claim 6 , wherein the second plurality of current patient parameters comprise the respiration rate of the patient, the heart rate of the patient, the temperature of the patient, the gestational age of the patient, the number of days since birth of the patient, and/or the oral sucking reflex of the patient each obtained at a second point in time earlier than the first point in time.

8. The method of claim 1 , wherein the historical data comprises a plurality of training datasets, each training dataset comprising patient parameters for a respective prior patient and one or more known outcomes for the respective prior patient, the patient parameters including a respiration rate of the respective prior patient, a heart rate of the respective prior patient, a temperature of the respective prior patient, a gestational age of the respective prior patient when weaned, a number of days after birth of the respective prior patient when weaned, an oral sucking reflex of the respective prior patient, and ambient conditions during or after weaning.
