Abstract

Systems for use with a medical device for reducing medication errors are provided. In one aspect, a system includes a medical device that is configurable with operating limit parameters for providing medication to a patient, and a limiting system. The limiting system includes a memory that includes patient-specific information for the patient and a database includes acceptable operating parameters for providing the medication to the patient using the medical device, and a processor. The processor is configured to compare the acceptable operating parameters with the patient-specific information, and provide a modification of the operating limit parameters for providing the medication to the patient based on the comparison of the acceptable operating parameters with the patient-specific information. Methods and machine-readable media are also provided.

First claim

What is claimed is:

1. A system, comprising:
a medical device that is configurable with operating limit parameters that limit operating parameters for providing medication to a patient; and
a limiting system comprising:
a memory comprising patient-specific information for the patient and a database comprising a plurality of sets of acceptable operating parameters for providing the medication to the patient using the medical device, the patient-specific information comprising patient demographic information and patient physiological information; and
a processor configured to:
compare the acceptable operating parameters with the patient-specific information before and during administration of the medication to the patient;
provide, to the medical device, a modification of the operating limit parameters based on the comparison of the patient-specific information with the acceptable operating parameters; and
provide a notification for display by the medical device indicating that the operating limit parameters for providing the medication to the patient have been modified based on the patient-specific information, the notification comprising information regarding the modified operating limit parameters,

wherein the medical device is configurable with the operating limit parameters for providing a mixture comprising a plurality of medications to the patient, wherein the acceptable operating parameters include acceptable operating parameters for providing the mixture to the patient using the medical device,
wherein the acceptable operating parameters comprise a plurality of rules indicating whether the patient-specific information comprises a value that is within or exceeds a threshold defined in accordance with a medical condition of the patient, and
wherein at least one of the rules indicates a maximum total amount of the medication to provide to the patient and a maximum total amount of the medication to provide to the patient over a period of time.

2. The system of claim 1 , wherein the patient demographic information comprises at least one of an age of the patient, a gender of the patient, a genetic makeup of the patient, or an ethnicity of the patient.

3. The system of claim 2 , wherein the patient physiological information includes at least one of a medication ordered for the patient, a time at which the medication is ordered for the patient, a treatment plan for the patient, a medication resistance of the patient, a weight of the patient, a height of the patient, or a body surface area of the patient.

4. The system of claim 3 , wherein the processor is configured to compare the acceptable operating parameters with the patient-specific information by comparing a first weight of the patient provided to the medical device with a second weight of the patient provided to a different currently running medical device.

5. The system of claim 1 , wherein the patient physiological information includes at least one of a medication ordered for the patient, a time at which the medication is ordered for the patient, a treatment plan for the patient, a medication resistance of the patient, a weight of the patient, a height of the patient, or a body surface area of the patient.

6. The system of claim 1 , wherein the medical condition is determinable based on laboratory data of the patient comprising a blood coagulation measure, a vitamin level, a platelet count value, a thromboplastin time, a weight, or a serum level.

7. The system of claim 1 , wherein the medical device comprises an infusion pump, and wherein the patient-specific information further comprises laboratory data for the patient.

8. The system of claim 1 , wherein the operating limit parameters comprise at least one of a rate at which to provide the medication, an amount of the medication to provide, and a length of time to provide the medication.

9. The system of claim 1 , wherein the processor is configured to provide the modification of the operating limit parameters based on the patient-specific information by defining at least one of a pair of a soft maximum value that can be exceeded and a hard maximum value that cannot be exceeded, or a soft minimum value that can be exceeded and a hard minimum value that cannot be exceeded for at least one operating limit parameter associated with delivery of the medication to the patient based on the patient-specific information.

10. The system of claim 1 , wherein the patient-specific information further comprises laboratory data for the patient, the laboratory data comprising at least one of a blood coagulation measure, a vitamin level, a platelet count value, a thromboplastin time, or a serum level.

11. A system, comprising:
a medical device that is configurable with operating limit parameters that limit operating parameters for providing medication to a patient; and
a limiting system comprising:
a memory comprising patient-specific information for the patient and a database comprising a plurality of sets of acceptable operating parameters for providing the medication to the patient using the medical device; and
a processor configured to:
compare the acceptable operating parameters with the operating limit parameters and the patient-specific information before and during administration of the medication to the patient;
generate modified operating limit parameters for the medical device based on the comparison of the patient-specific information with the acceptable operating parameters;
provide a notification for display by the medical device indicating the modified operating limit parameters;
receive an input from a caregiver for the patient, the input including information indicating whether the modified operating limit parameters are accepted; and
provide the operating limit parameters or the modified operating limit parameters to the medical device responsive to the received input,

wherein the medical device is configurable with the operating limit parameters for providing a mixture comprising a plurality of medications to the patient, wherein the acceptable operating parameters include acceptable operating parameters for providing the mixture to the patient using the medical device,
wherein the acceptable operating parameters comprise a plurality of rules indicating whether the patient-specific information comprises a value that is within or exceeds a threshold defined in accordance with a medical condition of the patient, and
wherein at least one of the rules indicates a maximum total amount of the medication to provide to the patient and a maximum total amount of the medication to provide to the patient over a period of time.

12. The system of claim 11 , wherein the input from the caregiver comprises an acknowledgment from the caregiver that one or more of the operating parameters is a value that is outside a soft limit and that this value is nevertheless to remain in force.

13. The system of claim 11 , wherein the input from the caregiver comprises an input to override the modified operating limit parameters, wherein the input from the caregiver comprises an indication of why the caregiver overrode the modified operating limit parameters, and wherein the processor is further configured to record when the caregiver overrides the modified operating limit parameters.

14. The system of claim 11 , wherein the processor is further configured to receive configuration parameters for determining whether to provide the notification to the medical device based on at least one of an identity of a caregiver, a location of the medical device, or an institutional preference.

15. The system of claim 14 , wherein
