Abstract

A computer-implemented method to process POC information for potential QC compliance issues. A system and method for implementation of traditional laboratory analyzer based QC compliance in point-of-care (POC) environments is disclosed. A specific system and method to analyze data from POC testing to identify when the testing exceeds the variation expected under stable operation (i.e., the testing is “out of control”) is disclosed. This system and method is characterized by solving the QC compliance problem for POC devices by individuals not trained in traditional laboratory practices. This also provides the capability in real-time or near real-time to analyze POC testing information regarding the performance of each POC device, reagent kit (i.e., one kit per analyte tested) and/or lot, and operator so one can respond quickly to a particular device, reagent kit and/or lot, or operator that is not performing properly.

Claims

1. A method of providing automatic quality control (QC) compliance for point-of-care (POC) devices, comprising the steps of:

storing test results received from each of a plurality of POC devices, including an association with the operator of the POC device and/or a reagent used in obtaining the test results;

processing the results to detect any random and/or systemic exception from results that have previously been stored;

holding for review POC-collected patient results associated with a QC compliance exception;

delaying the reporting or transfer to an information system of potentially inaccurate patient results if said detecting step indicates the presence of a random or systematic exception; and

automatically disabling a questionable POC device based on detection of a QC compliance exception.

2. A method of providing automatic quality control (QC) compliance for point-of-care (POC) devices, comprising the steps of:

storing test results received from each of a plurality of POC devices, including an association with the operator of the POC device and/or a reagent used in obtaining the test results;

processing the results to detect any random and/or systemic exception from results that have previously been stored;

holding for review POC-collected patient results associated with a QC compliance exception; and

automatically invalidating a reagent lot that has established a QC exception by configuring a selected POC device.

3. A method of providing automatic quality control (QC) compliance for point-of-care (POC) devices, comprising the steps of:

storing test results received from each of a plurality of POC devices, including an association with the operator of the POC device and/or a reagent used in obtaining the test results;

processing the results to detect any random and/or systemic exception from results that have previously been stored;

holding for review POC-collected patient results associated with a QC compliance exception; and

automatically invalidating an operator who has established a QC exception by configuring a selected POC device.

4. A method of providing automatic quality control (QC) compliance for point-of-care (POC) devices, comprising the steps of:

storing test results received from each of a plurality of POC devices, including an association with the operator of the POC device and/or a reagent used in obtaining the test results, and

processing the results to detect any random and/or systemic exception from results that have previously been stored; and

graphically presenting QC exceptions.

5. A method as claimed in claim 4 wherein the administrator can establish via an interface to a storage database the rules for defining the exceptions.

6. A method as claimed in claim 5 wherein the step of establishing rules includes a choice made on the interface between analyzing the data for random error or systemic error.
