Abstract

An automated method for evaluating completeness of clinical data being transferred from a clinical device. The clinical data includes continuously logged data, intermittently logged data, and timestamp data associated with each of the continuously logged data and intermittently logged data. The method is executed by a processor and includes receiving the clinical data from the clinical device and based on the timestamp data associated with the continuously logged data, determining a time span over which the continuously logged data was obtained. The timestamp data associated with the intermittently logged data is compared with the determined time span. If any timestamp data associated with the intermittently logged data does not occur within the determined time span, an alert is issued indicating that the continuously logged data of the clinical data is incomplete.

First claim

What is claimed is:

1. An automated method for evaluating completeness of data from a clinical device, the clinical data comprising continuously logged data, intermittently logged data including one or more logged alarms indicating a detected adverse operating condition of the clinical device, and timestamp data associated with the continuously logged data and intermittently logged data, the method comprising:
receiving via a wireless interface over the air, a time-ordered waveform that includes the clinical data from the clinical device;
extracting, via a processor, the timestamp data associated with the continuously logged data from the time-ordered waveform, the extracting including detecting occurrences of signal deviations in the received time-ordered waveform;
determining a time span over which the continuously logged data was obtained based at least in part on the extracted timestamp data, the determining being based at least in part on determining an earliest data point of alarm data and a latest data point of alarm data, the earnest data point and latest data point being determined from the timestamp data;
comparing the timestamp data associated with the intermittently logged data with the determined time span;
comparing timestamps of different types of data to determine when the different types of data do not begin and end at a same time, the timestamps of different types of data being distinguishable by different signal deviations in the received time-ordered waveform; and
when the time stamps of different types of data do not begin and end at a same time, then issuing an alert that at least one of the different types of data were not extracted.

2. The method of claim 1 , wherein receiving the clinical data from the clinical device comprises receiving the intermittently logged data before receiving the continuously logged data.

3. The method of claim 1 , wherein the continuously logged data comprises one or more operating parameters of the clinical device.

4. The method of claim 3 , wherein the clinical device is a blood pump, and wherein the operating parameters of the blood pump comprises one or more of a flow rate of blood exiting the pump, power supplied to the pump, and motor speed of the pump.

5. The method of claim 1 , wherein the intermittently logged data further comprises:
one or more logged events indicating a change in operation of the clinical device.

6. The method of claim 5 , wherein the clinical device is a blood pump, and wherein the intermittently logged data comprises at least one of:
a low flow alarm;
a suction condition alarm;
a low battery alarm; and
a power disconnection alarm.

7. The method of claim 1 , wherein the clinical data further comprises patient data and clinical device data that are not associated with a timestamp.

8. The method of claim 1 , wherein the clinical device is ventricular assist device or a blood pump.

9. The method of claim 1 , wherein the recited steps are performed at a location of the clinical device, and further comprising, if all timestamp data associated with the intermittently logged data occurs within the determined time span, transmitting the clinical data over a network to a remote destination.

10. The method of claim 1 , wherein the recited steps are performed at an originating location remote from the clinical device, and wherein the clinical data is received over a network connection from an originating location, and wherein the alert indicating that the continuously logged data of the clinical data is incomplete is transmitted over the network to the originating location.

11. An apparatus for evaluating completeness of clinical data being transferred from a clinical device, the clinical data comprising continuously logged data, intermittently logged data, and timestamp data associated with each of the continuously logged data and intermittently logged data including one or more logged alarms indicating a detected adverse operating condition of the clinical device, the apparatus comprising;
a wireless interface configured to wirelessly receive a time-ordered waveform that includes the clinical data from the clinical device; and processing circuitry configured to:
extract the timestamp data associated with the continuously logged data from the time-ordered waveform, the extracting including detecting occurrences of signal deviations in the received time-ordered waveform;
determine a time span over which the continuously logged data was obtained based at least in part on the extracted timestamp data, the determining being based at least in part on determining an earnest data point of alarm data and a latest data point of alarm data, the earnest data point and latest data point being determined from the timestamp data;
compare the timestamp data associated with the intermittently logged data with the determined time span;
compare timestamps of different types of data to determine when the different types of data do not begin and end at a same time, the timestamps of different types of data being distinguishable by different signal deviations in the received time-ordered waveform; and
when the time stamps of different types of data do not begin and end at a same time, then issue an alert that at least one of the different types of data were not extracted.

12. The apparatus of claim 11 , wherein the processor is configured to determine whether the intermittently logged data is received before the continuously logged data.

13. The apparatus of claim 11 , wherein the continuously logged data comprises one or more operating parameters of the clinical device.

14. The apparatus of claim 13 , wherein the clinical device is a blood pump, and wherein the operating parameters of the blood pump comprises one or more of a flow rate of blood exiting the pump, power supplied to the pump, and motor speed of the pump.

15. The apparatus of claim 11 , wherein the intermittently logged data further comprises:
one or more logged events indicating a change in operation of the clinical device.

16. The apparatus of claim 15 , wherein the clinical device is a blood pump, and wherein the intermittently logged data comprises at least one of:
a low flow alarm;
a suction condition alarm;
a low battery alarm; and
a power disconnection alarm.

17. The apparatus of claim 11 , wherein the clinical data further comprises patient data and clinical device data that are not associated with a timestamp.

18. The apparatus of claim 11 , wherein the apparatus is located in proximity to the clinical device, and the processor is further configured to, if all timestamp data associated with the intermittently logged data occurs within the determined time span, transmit the clinical data over a network to a remote destination.

19. The apparatus of claim 11 , wherein the apparatus is located remote from the clinical device, and wherein the apparatus receives the clinical data over a network connection from an originating location, and wherein the processor is further configured to transmit the alert indicating that the continuously logged data of the clinical data is incomplete over the network to the originating location.
