Vital sign monitors for inpatient medicine wards
Systems and methods for vital sign monitors are disclosed herein. In some cases, a warning score is calculated based on first measurements of a first biological condition and second measurements of a second biological condition. In particular cases, the first measurements and the second measurements are automatically measured during the same time period. The warning score may be calculated based on an average of the first measurements and an average of the second measurements. Based on determining that the warning score is outside of a predetermined range, a clinical device may output an alert.
1. A system, comprising:
at least one processor; and
at least one memory storing instructions that, when executed by the at least one processor, cause the processor to perform operations comprising:
receiving, from at least one sensor, first measurements of a biological condition of an individual determined during a first time period;
determining a first average of the first measurements;
receiving, from the at least one sensor, second measurements of the biological condition of the individual determined during a second time period, the second time period at least partially occurring 24 hours after the first time period and being shorter than the first time period;
determining a second average of the second measurements;
determining a circadian offset based on a difference between the first average and the second average;
determining whether the circadian offset is outside of a predetermined range; and
based on determining that the circadian offset is outside of the predetermined range, causing a clinical device to output an alert associated with the individual.
2. The system of claim 1 , the biological being a first biological condition, the predetermined range being a first predetermined range, wherein the operations further comprise:
receiving, from the at least one sensor, third measurements of a second biological condition of the individual determined during the second time period;
determining a third average of the third measurements;
determining a warning score based on the second average and the third average; and
determining whether the warning score is outside of a second predetermined range, and
wherein causing the clinical device to output the alert is performed based on determining that the warning score is outside of the second predetermined range.
3. The system of claim 1 , wherein the first time period is between one hour and eight hours, and wherein the second time period is between half of an hour and four hours.
4. The system of claim 1 , wherein determining the second average comprises:
determining a line-of-best-fit for the second measurements;
determining the second average based on the line-of-best-fit.
5. The system of claim 4 , wherein determining the second average based on the line-of-best fit comprises:
determining a raw average of the second measurements;
determining a correction by multiplying a slope of the line-of-best-fit by half of the second time period; and
determining a corrected average by adding the raw average to the correction.
6. The system of claim 1 , wherein causing the clinical device to output the alert comprises transmitting, to the clinical device, an instruction to output a user interface indicating the alert.
7. The system of claim 6 , wherein the instruction is to output the alert as at least one of an auditory signal, a haptic signal, or a visual signal.
8. The system of claim 1 , the individual being a first individual, the circadian offset being a first circadian offset, the operations further comprising:
determining a second circadian offset associated with a second individual is within the predetermined range;
wherein causing the clinical device to output the alert associated with the first individual comprises causing the clinical device to output the alert associated with the first individual with an indication that the second individual has a non-alert status.
9. The system of claim 1 , wherein the system comprises the at least one sensor, the at least one sensor comprising at least one automated sensor .
10. The system of claim 1 , wherein the system comprises the clinical device.
11. A method, comprising:
receiving, from at least one sensor, first measurements of a biological condition of an individual determined during a first time period;
determining a first average of the first measurements;
receiving, from the at least one sensor, second measurements of the biological condition of the individual determined during a second time period,
at least part of the second time period occurring 24 hours after the first time period, and
the second time period being shorter than the first time period;
determining a second average of the second measurements;
determining a circadian offset based on a difference between the first average and the second average;
determining whether the circadian offset is outside of a predetermined range; and
based on determining that the circadian offset is outside of the predetermined range, causing a clinical device to output an alert associated with the individual.
12. The method of claim 11 , the biological being a first biological condition, the predetermined range being a first predetermined range, wherein the method further comprises:
receiving, from the at least one sensor, third measurements of a second biological condition of the individual determined during the second time period;
determining a third average of the third measurements;
determining a warning score based on the second average and the third average; and
determining whether the warning score is outside of a second predetermined range,
wherein the clinical device is caused to output the alert based on determining that the warning score is outside of the second predetermined range.
13. The method of claim 11 , wherein the first time period is between one hour and eight hours, and
wherein the second time period is between half of an hour and four hours.
14. The method of claim 11 , wherein determining the second average comprises:
determining a line-of-best-fit for the second measurements; and
determining the second average based on the line-of-best-fit.
15. The method of claim 14 , wherein determining the second average based on the line-of-best fit comprises:
determining a raw average of the second measurements;
determining a correction by multiplying a slope of the line-of-best-fit by half of the second time period; and
determining a corrected average by adding the raw average to the correction.
16. The method of claim 11 , wherein causing the clinical device to output the alert comprises transmitting, to the clinical device, an instruction to output a user interface indicating the alert.
17. The method of claim 16 , wherein the instruction is to output the alert as at least one of an auditory signal, a haptic signal, or a visual signal.
18. The method of claim 11 , the individual being a first individual, the circadian offset being a first circadian offset, the method further comprising:
determining a second circadian offset associated with a second individual is within the predetermined range;
wherein causing the clinical device to output the alert associated with the first individual comprises causing the clinical device to output the alert associated with the first individual with an indication that the second individual has a non-alert status.
