Patent Application
20150095058
Patient samples, such as blood samples, are often collected at one location and then shipped to a diagnostic laboratory for testing and analysis. The results are then reported electronically or by mail to the patient, as well as the physician requesting the tests. However, between shipment and reporting, the patient or physician generally do not receive further information regarding the status of the sample. Due to the serious nature of the testing performed, patients and physicians may require further information regarding the status of the collected sample. In particular, physicians may wish to monitor the status to better manage their practice and prepare treatment plans.
Existing software, such as Laboratory Information Systems (LIS) allow the internal tracking of laboratory workflows indicating when a sample is accessioned, enters into the lab, and completes the workflow. The LIS also tracks and manages the reporting process for providing the results to the requesting party. The existing software, however, does not provide external updates on the workflow with respect to specific devices and departments within the laboratory setting to provide updates related to the status of the sample to the requesting party. Further, the LIS only tracks the workflow after accession into the laboratory itself, and does not provide updates on the status of the sample throughout the lifecycle from shipment to the reporting of the results.
The present invention is directed to overcoming these and other deficiencies in the art.
One aspect of the present invention relates to a method of managing and tracking a collected laboratory sample including receiving, by a sample management computing device, a patient identifier related to the collected laboratory sample and laboratory-workflow information related to the collected laboratory sample.

The tracking process includes obtaining, by the sample management computing device, location information from one or more sample preparatory stations or sample analysis stations being used to prepare or analyze the collected laboratory sample based on the received laboratory-workflow information. Completion information related to the laboratory-workflow information is obtained indicating that the collected laboratory sample been prepared and analyzed by all designated sample preparatory stations or sample analysis stations. A status of the collected laboratory sample is provided after obtaining the shipment information, the location information, the completion information, or a combination thereof.
Another aspect of the invention relates to a sample management computing device including a processor coupled to a memory and configured to execute programmed instructions stored in the memory, comprising receiving a patient identifier related to the collected laboratory sample and laboratory-workflow information related to the collected laboratory sample. Shipment information is obtained for the collected laboratory sample based on the received patient identifier. A tracking process is initiated after the shipping information has been obtained. The tracking process includes obtaining location information from one or more sample preparatory stations or sample analysis stations being used to prepare or analyze the collected laboratory sample based on the received laboratory-workflow information. Completion information related to the laboratory-workflow information is obtained indicating that the collected laboratory sample been prepared and analyzed by all designated sample preparatory stations or sample analysis stations. A status of the collected laboratory sample is provided after obtaining the shipment information, the location information, the completion information, or a combination thereof.
Yet another aspect of the present invention relates to a non-transitory computer readable medium having stored thereon instructions for managing and tracking a collected laboratory sample comprising machine executable code which when executed by a processor, causes the processor to perform steps including receiving a patient identifier related to the collected laboratory sample and laboratory-workflow information related to the collected laboratory sample.

An example of a method of managing and tracking a collected laboratory sample will now be described with reference to
In step 102, the sample management computing device 14 receives laboratory-workflow information related to the collected laboratory sample. The labatory-workflow information is input into one of the client devices 12(1)-12(n), for example by the physician who requested the collection of the sample, or the lab technician at the diagnostic laboratory who is processing the sample, through the user input device and is received by sample management computing device 14 via communication network 19(1). The laboratory-workflow information indicates the diagnostic testing to be performed on the collected sample, such as testing a blood sample for markers of cardiovascular and other related diseases, although other diagnostic tests and procedures may be indicated in the laboratory-workflow information. The laboratory-workflow information may be encoded, along with the patient identifier, in the at least one of the barcode, RFID tag, or QR code located on the container holding the collected sample.
In step 104, the sample management computing device 14 obtains shipment information for the collected laboratory sample based on the received patient identifier. In one embodiment, the shipment information is received from one of the shipment tracking servers 16(1)-16(n) via communication network 19(2). The shipment information includes tracking information indicating the shipment status of the collected sample, such as en route to the diagnostic laboratory, at a shipment facility, or delivered to the diagnostic laboratory. In one embodiment, the sample management computing device 14 stores a list of shipping bills generated by the diagnostic laboratory and associated with a shipping company who maintains one of the shipment tracking servers 16(1)-16(n). The generated shipping bills may be utilized by a particular physician practice or blood draw location to ship collected samples to the diagnostic laboratory. The list of shipping bills may be stored in memory 22, although the list of generated shipping bills may be stored in other locations on other devices. The sample management computing device 14 then queries one of the shipment tracking servers 16(1)-16(n) associated with one or more of the generated shipping bills to determine whether the shipping bills have been utilized. Upon matching one of the generated shipping bills to a utilized shipping bill, the sample management computing device 14 then queries the one of the shipment tracking servers 16(1)-16(n) associated with the shipping bill to identify the collected samples included in the shipment based on the received patient identifier. In another embodiment, a shipping notification is received from one of the client devices 12(1)-12(n) associated with a laboratory sample collector, such as a physician's office or a blood draw location. After receipt of the shipment notification, the sample management computing device 14 obtains further status updates from one of the shipment tracking servers 16(1)-16(n) associated with the delivery.
Next, in step 106 the sample management computing device 14 provides a status update based on the shipment information obtained in step 104. The status update may be provided to one of the client devices 12(1)-12(n) for display thereon, for example, via a web portal or dashboard interface. Upon matching a generated shipping bill to a utilized shipping bill and identifying the patient identifier associated with a collected sample, the shipment management computing device 14 provides a status update indicating the collected sample is en route to the diagnostic laboratory. Upon receiving confirmation from one of the shipment tracking servers 16(1)-16(n) that the shipment has been delivered, the sample management computing device may provide a status update to one of the client devices 12(1)-12(n) indicating the updated status. In one embodiment, the status updates may be provided as an icon indicative of the shipment status, such as a delivery truck for an en route shipment or a package for a delivered status, although other methods may be used to provide the status updates.
In step 108, the sample management computing device 14 initiates a tracking process. In one example, upon delivery to the diagnostic laboratory, the collected sample is scanned into a Laboratory Information System (LIS), which tracks the laboratory workflow, utilizing the at least one of the barcode, RFID tag, or QR code located on the container holding the collected sample, although other methods of initiating the tracking process may be utilized. Once the tracking process is initiated, the sample management computing device 14 tracks the location of the collected sample as it proceeds through the laboratory workflow. The collected sample may further be associated with a patient record stored in database 23 based on the patient identifier associated with the collected sample.
In step 110, the sample management computing device 14 obtains location information from one or more sample preparatory stations or sample analysis stations being used to prepare or analyze the collected laboratory sample based on the received laboratory-workflow information. The location information indicates the location of the collected sample within the diagnostic laboratory and the status within the laboratory workflow. In one embodiment, the location information further includes a time stamp to indicate the time when the location information is collected. The location information may indicate a particular department, such as an autochemistry department or a genotyping department, although other departments within the diagnostic laboratory may be indicated. The location information may further indicate particular sample handling and analyzing stations associated with certain laboratory instruments within the diagnostic laboratory, such as a liquid handling apparatus, a mass spectometry instrument, an immunoassay instrument, a genotyping instrument, an electrophoresis instrument, a blood preparation instrument, a clinical chemistry analyzer, an NMR instrument, a refrigerator, or combinations thereof, although the location information may indicate other sample handling or analyzing instruments. The departments or laboratory instruments are each associated with one of the sensor devices 18(1)-18(n), such as an RFID reader, scanner, camera, or a manual bar code reader, although other sensor devices 18(1)-18(n) associated with the laboratory instruments may be utilized to provide the location information to the sample management device 14 over communication network 19(3).
By way of example only, the laboratory workflow for a collected sample may indicate NMR testing is required. The NMR instrument may be associated with one of the sensor devices 18(1)-18(n), such as a designated barcode reader. Prior to NMR testing, a barcode on the container housing the collected sample may be scanned at the barcode reader associated with the NMR instrument. The NMR instrument then provides the location information to the sample management computing device 14 via communication network 19(2).
Next, in step 112, the sample management computing device 14 provides a status update based on the location information obtained in step 110. The status update is provided for display on one of the client devices 12(1)-12(n), by way of example through a web portal. The status update includes information related to the location of the collected sample within the laboratory workflow, such as accessioning, a particular department, a sample handling or analysis station, or a particular laboratory instrument, although other information related to the location of the collected sample may be provided in the status update. The status update may be provided as an icon indicative of the location of the collected sample. By way of example only, if the collected sample is in the autochemistry department, a Beckman AU instrument may be displayed on the web portal of one of the client devices 12(1)-12(n), or if the collected sample is in preparation for genotyping, a PCR instrument may be displayed, although other icons may be utilized to represent other locations within the diagnostic laboratory.
In step 114, the sample management computing device 14 determines whether completion information indicating that the collected laboratory sample been prepared and analyzed by all designated sample preparatory stations or sample analysis stations in the laboratory workflow has been obtained. The completion information may include a generated report of the testing results. In one example, the completion information may include confirmation from one of the shipment tracking servers 16(1)-16(n) that the generated report has been delivered to a physician's office or other delivery location. In another example, the completion information may indicate that an electronic version of the generated report has been presented via a regulatory compliant secure system. If in step 114 the sample management computing device 14 determines that the completion information has not been obtained then the No branch is taken back to step 110 where the sample management computing device 14 obtains additional location information from sample preparatory stations or sample analysis stations.
If in step 114, the sample management computing device 14 determines that the completion information has been obtained, the Yes branch is taken to step 116 where the sample management computing device 14 provides a status of the collected laboratory sample related to the completion information. The status update indicates that the laboratory workflow has been completed, i.e., that the collected laboratory sample been prepared and analyzed by all designated sample preparatory stations or sample analysis stations in the laboratory workflow and that the results are ready for reporting. The status update may further indicate that the generated report has been successfully delivered, either by shipment or in electronic format. The status updated related to the completion information may be indicated by an icon indicative of the status, such as a final report icon to indicate that the report of the results has been generated.
