Abstract

Improved systems and methods are provided for monitoring compliance with an order for a patient specimen. Broadly, an inventive system incorporates a machine readable wireless identification and sensor technology to provide feedback to a caregiver regarding compliance with a specimen order. In particular, a system for monitoring compliance with an order for a specimen is provided which includes a specimen container having an attached machine readable wireless tag. The tag contains specimen container characteristic information. The tagged container aids in indicating to a user whether the correct specimen container type has been chosen. Further, a system is provided which includes a sensor useful in indicating whether a sufficient quantity of specimen has been obtained in order to perform the requested laboratory test as part of the patient'"'"'s care.

Claims

1. A system for monitoring compliance with an order for a specimen, comprising:

a specimen container comprising a machine readable wireless tag;

the tag containing specimen container characteristic information;

a device having data input and output capacity, processing circuitry, memory circuitry and an executable program for analysis of data transmitted from the tag;

a machine readable wireless reader in data communication with the tag and the device; and

a display disposed on the device or the reader.

2. The system of claim 1 wherein the specimen container characteristic information is selected from the group consisting of:

a specimen container type, container identification information, weight of the container when empty, weight of the container containing a volume of specimen, opacity of the container and opacity of the container containing a volume of specimen.

3. The system of claim 1 wherein the specimen container characteristic information is selected from the group consisting of:

patient identification information identifying a patient whose specimen is to be contained in the specimen container, a test to be performed on the specimen, and an amount of specimen required.

4. The system of claim 1 wherein the reader is disposed on the device.

5. The system of claim 1 further comprising a patient identification badge having an attached radio frequency identification tag.

6. The system of claim 1 wherein the tag is selected from the group consisting of:

passive, active, read-only and read-write.

7. The system of claim 1 wherein the device is selected from the group consisting of:

a personal digital assistant, a personal computer a mainframe and a server.

8. The system of claim 1 wherein the display is selected from the group consisting of:

a display screen, a light signal emitter, and an acoustic signal emitter.

9. The system of claim 1 further comprising a specimen container holder having a receptacle for removably receiving the specimen container.

10. The system of claim 9 further comprising a sensor disposed in contact with the receptacle, the sensor in data transmission communication with the device.

11. The system of claim 10 wherein the sensor is a weight sensor.

12. The system of claim 10 wherein the sensor is an opacity sensor.

13. The system of claim 10 wherein the device further comprises an executable program for analysis of data transmitted from the sensor.

14. The system of claim 13 wherein the radio frequency identification reader is disposed on the holder.

15. The system of claim 13 wherein the device having data input and output capacity, processing circuitry, memory circuitry and an executable program for analysis of data transmitted from the tag is disposed on the holder.

16. A method for monitoring compliance with an order for a specimen, comprising the steps of:

providing a system according to claim 1;

inputting an order for a patient specimen to the memory, the order requiring use of a first type of specimen container in order to comply with the order;

selecting a specimen container;

activating a wireless machine reader to read the tag attached to the specimen container, the tag containing information indicative of the container type;

transmitting the information contained in the tag from the reader to the device;

retrieving the record of the order for a patient specimen requiring use of the first type of specimen container;

comparing the information contained in the tag read by the reader identifying the container type with the container type required by the order to determine whether the container having the attached tag read by the reader is the first type of specimen container required in order to comply with the order; and

presenting information on the display indicating whether the specimen container having the attached tag read by the reader is the first type of specimen container required in order to comply with the order, thereby monitoring compliance with an order for a specimen.

17. The process of claim 16 further comprising the step of confirming the identity of the patient as a patient for whom the order for a patient specimen was placed.

18. A method for monitoring compliance with an order for a specimen, comprising the steps of:

providing a system according to claim 10;

inputting an order for a patient specimen to the memory, the order requiring a specified quantity of a patient specimen in order to comply with the order;

obtaining a quantity of the patient specimen from a patient;

introducing the quantity of the specimen in the specimen container;

placing the specimen container in a receptacle of the specimen container holder, the receptacle having a sensor for measuring the quantity of the patient specimen disposed thereon;

transmitting a sensor signal from the sensor to the device having data input and output capacity, processing circuitry, memory circuitry and an executable program for analysis of data transmitted from the sensor;

retrieving the record of the order for a patient specimen requiring the specified quantity of a patient specimen in order to comply with the order;

comparing the signal transmitted by the sensor indicative of the quantity of specimen in the container with the specified quantity of a patient specimen required by the order to determine whether the quantity of specimen in the container is sufficient in order to comply with the order; and

presenting information on the display indicating whether the quantity of specimen in the container is sufficient in order to comply with the order, thereby monitoring compliance with an order for a specimen.

19. The process of claim 18 further comprising the step of confirming the identity of the patient as a patient for whom the order for a patient specimen was placed.

20. The process of claim 18 further comprising the steps of:

inputting an indicator that the patient specimen required by the order has been obtained;

activating the radio frequency reader to read the tag attached to the specimen container, the tag containing information indicative of a unique container identifier;

transmitting the information to the memory; and

associating the information with the indicator that the patient specimen has been obtained.
