Abstract

Medical monitoring systems and methods are disclosed. A medical monitoring system can receive physiological parameter data and first physiological parameter alarm data from a plurality of patients. The first physiological parameter alarm data can be indicative of alarm conditions experienced by the plurality of patients. The alarm conditions can have been detected based upon first alarm criteria. The system can also generate second physiological parameter alarm data using a processor. The second physiological parameter alarm data can be indicative of simulated alarm conditions, which can be detected based upon a second alarm criteria. The system can compare the first and second physiological parameter alarm data using a processor.

Claims (22)

1. A method for analyzing physiological parameter monitoring data, the method comprising:

receiving physiological parameter data from a plurality of patients using a processor;

receiving first physiological parameter alarm data from the plurality of patients using the processor, the first physiological parameter alarm data being indicative of alarm conditions experienced by the plurality of patients, the alarm conditions having been detected based upon a first alarm criteria;

generating second physiological parameter alarm data using the processor, the second physiological parameter alarm data being indicative of simulated alarm conditions, the simulated alarm conditions being detected based upon a second alarm criteria; and

comparing the first and second physiological parameter alarm data using the processor.

2. The method of claim 1 , wherein generating second physiological parameter alarm data comprises applying an alarm detection algorithm to the physiological parameter data, the alarm detection algorithm being substantially similar to an alarm detection algorithm used to generate the first physiological parameter alarm data.

3. The method of claim 1 , further comprising receiving medical intervention data indicative of medical interventions experienced by the plurality of patients.

4. The method of claim 3 , further comprising correlating medical interventions from the medical intervention data with alarm conditions from the first physiological parameter alarm data.

5. The method of claim 3 , further comprising estimating false negative events based upon the medical intervention data.

6. The method of claim 5 , further comprising determining whether the false-negative events are detected using the second alarm criteria.

7. The method of claim 3 , further comprising estimating, based upon the medical intervention data, which of the alarm conditions in the first physiological parameter alarm data are false positive alarms.

8. The method of claim 7 , further comprising determining whether the false positive alarms are detected using the second alarm criteria.

9. The method of claim 3 , further comprising estimating, based upon the medical intervention data, which of the alarm conditions in the first physiological parameter alarm data correspond to actual instances of medical duress experienced by a patient.

10. The method of claim 9 , further comprising determining whether the actual instances of medical duress are detected using the second alarm criteria.

11. The method of claim 1 , wherein comparing the first and second physiological parameter alarm data comprises determining the difference between the number of alarm conditions and the number of simulated alarm conditions.

12. The method of claim 1 , wherein the physiological parameter data is received from a plurality of bedside patient monitoring devices.

13. The method of claim 1 , wherein the first alarm criteria comprises a first threshold value of the medical parameter, and wherein the second alarm criteria comprises a second threshold value of the medical parameter.

14. A computer-readable medium comprising instructions that, when read by a computer, cause the computer to perform a method for analyzing physiological parameter monitoring data, the method comprising:

receiving physiological parameter data from a plurality of patients;

receiving first physiological parameter alarm data from the plurality of patients, the first physiological parameter alarm data being indicative of alarm conditions experienced by the plurality of patients, the alarm conditions having been detected based upon a first alarm criteria;

generating second physiological parameter alarm data using a processor, the second physiological parameter alarm data being indicative of simulated alarm conditions, the simulated alarm conditions being detected based upon a second alarm criteria; and

comparing the first and second physiological parameter alarm data using the processor.
