MULTI-MODALITY AUTOMATIC EXAM START NOTIFICATION AND PATIENT INFORMATION AUTO-QUERY MECHANISM

Abstract

A system and method for beginning an exam procedure in multiple modality systems during the performance of a physiology procedure. Upon the initiation of a physiology procedure in a physiology workstation, the physiology workstation automatically generates an exam notification message to each modality system required during the performance of the physiology procedure. Upon receiving the start exam notification message, each modality system automatically generates a patient information query back to the physiology workstation requesting patient information and exam information. The physiology workstation returns identical patient information and exam information to each of the modality systems, thereby ensuring that each of the modality systems is operating utilizing the same patient information and exam information. The generation of both the start exam notification message and the patient information query are automatically generated, such that an exam procedure can be initiated by a single manual entry into the physiology workstation, thus eliminating the requirement of manual initiation of each of the individual modality systems.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates a physiology workstation 10 that can be located in the control room or procedural room of a catheter lab, hemodynamic (HD) lab or electrophysiology (EP) lab and can be utilized in connection with HD, EP or ablation procedures, among other things. The physiology workstation 10 may integrate, among other things, real-time hemodynamic information, real-time intracardiac echography, fluoroscopic images, mapping data and pre-surgery planning CT and MR images. The physiology workstation 10 offers integrated monitoring and review of hemodynamic, EP, patient and mapping information, as well as stored and real-time diagnostic images, ECG signals and IC signals.

The physiology workstation 10 is operable to acquire patient monitoring data, whether it be hemodynamic or electrophysiological data, from the patient, such as during the performance of a catheterization procedure. In a networked system, the physiology workstation 10 communicates the received monitoring data to a central data storage device or server 12 that stores the patient monitoring data for access and review by a physician from a remote review station. In addition to storing monitoring data onto the server 12, the physiology workstation 10 can also retrieve patient information from the server 12 that may be required during the completion of a physiology procedure.

As an example, the physiology workstation 10 can receive signals from various different devices, such as intracardiac signals from EP catheters, patient monitoring signal (e.g. from a blood pressure cuff, SpO2 monitor, temperature monitor, CO₂ level, and the like), ECG signals from surface ECG leads, pressure signals from open lumen catheters and intracardiac signals. Further, the physiology workstation 10 can also receive other information from modality systems that are required to conduct the physiology procedure on the patient. In the embodiment of the invention illustrated in FIG. 1, the physiology workstation 10 can receive imaging data from an x-ray modality system 14, ultrasound images from an ultrasound modality system 16, or other types of images/data from various different modality systems, as generally shown by reference numeral 18. As an example, the other modality systems could include x-ray angiography systems, fluoroscopic imaging data from a fluoroscopic modality system or any other type of modality system that may be required for the performance of a physiology procedure.

When a clinician/physician desires to begin a physiology procedure, whether the procedure is scheduled or is being performed on an emergency basis, the physician initially begins the procedure by identifying the patient in the physiology workstation 10. The identification of the patient typically requires the physician/clinician to utilize the physiology workstation 10 to access patient information/records from the server 12 using a network connection 20. If the patient information is not contained within the server 12, the operator can manually enter the required information into the physiology workstation 10 through a manual entry means, such as a keyboard. In addition to retrieving patient information from the server 12, the operator also selects the type of physiology procedure that is going to be performed on the patient, as is illustrated in steps 22 and 24 of FIG. 3. As an example, if the operator is going to conduct a hemodynamic catheter procedure, the procedure may require various different operating components in addition to the x-ray modality system 14 shown in FIG. 2. As illustrated in FIG. 1, the physiology workstation 10 is in data communication with the x-ray modality system 14, the ultrasound modality system 16 and various other modality systems 18. Thus, the physiology workstation 10 can communicate with the various modality systems 14, 16 and 18 during the performance of a physiology procedure on a patient.

As illustrated in FIGS. 1 and 3, once the operator has indicated the start of a physiology procedure in the physiology workstation 10, the physiology workstation 10 initially identifies which modality systems are required for the physiology procedure, as indicated in step 24. Once the physiology workstation 10 has determined which modality systems are required, the physiology workstation 10 relays a “start exam” notification 26 to each of the modality systems 14, 16 and 18 required for the procedure, as illustrated by step 28 in FIG. 3. Although FIG. 1 illustrates the notification message 26 being sent to each of the modality systems 14, 16 and 18, it should be understood that the “start exam:” notification message 26 will preferably be sent to only the modality system or systems that are required for performance of the physiology procedure to be carried out on the patient. As an example, if the hemodynamic procedure requires the use of the x-ray modality system 14 but not the operation of the ultrasound modality system 16, the physiology workstation 10 will send the “start exam” notification 26 only to the x-ray modality system 14.

Once the modality system receives the “start exam” notification 26, the modality system 14 must obtain the patient and examination information for the procedure that is being conducted. In the embodiment illustrated in the Figures, each modality system 14 that receives the “start exam” notification 26 begins preparing for the required operation for the identified procedure. Initially, each modality system required for the performance of the physiology procedure automatically generates a patient information query 30 to the physiology workstation 10 requesting patient and exam information corresponding to the individual undergoing the procedure. Each modality system 14, 16 and 18 that is involved with the procedure being performed needs patient information such that the results of the procedure can be properly correlated with the patient undergoing treatment. The patient information may include information such as the patient's name, sex, age, patient identification number and any other information required to correlate the procedural results with the patient undergoing the procedure. In addition to the workstation 10, the patient information could be received from other sources, such as a departmental scheduling system or an ADT system.

Once the physiology workstation 10 receives the request for patient information, as illustrated in step 32 in FIG. 3, the physiology workstation 10 exchanges the patient information with the requesting modality 14, 16 or 18. Once the patient information is relayed to the requesting modality system, as illustrated in step 34, the requesting modality system will be properly synchronized with the physiology workstation 10, including containing the same patient identification information. Thus, all of the modality systems include identical patient and exam information such that the procedural results can be properly correlated and stored within the physiology workstation 10.

Once each of the modality systems that are required for the performance of the physiology procedure have received the patient identification and exam information, the physiology workstation 10 and the modality systems 14, 16 or 18 can begin the performance of the physiology procedure, as illustrated in step 36 of FIG. 3. As can be appreciated in FIGS. 1 and 3, the physiology procedure to be conducted is initiated by a manual entry into the physiology workstation 10. Upon receiving the manual entry, the physiology workstation generates an automatic “start exam” notification message to each of the modality systems that are required for the procedure. Upon receiving the automatically generated start procedure notification message, the modality systems involved in the procedure obtain patient identification information and exam identification information from the physiology workstation 10. Once this information has been received, each of the modality systems can begin to carry out the examination procedure and relay the monitoring data to the physiology workstation 10 for viewing and storage in a conventional manner. The physiology workstation 10 may selectively record the monitoring data at the remote server 12, which may be part of the hospital information system (HIS).

Although the embodiment of the invention shown in FIG. 1 contemplates an automatic notification sent to each of the modality systems involved in the procedure, it should be understood that the automatic “start exam” notification message could be sent to any type of equipment that is required for performing the physiology procedure on the patient such that all of the modality systems and equipment required for performing the procedure are provided with the identical patient and examination information.

Referring now to FIG. 2, thereshown is an alternate embodiment of the system shown in FIG. 1. In the embodiment shown in FIG. 2, the physiology procedure to be performed on the patient is initiated by a manual entry into the ultrasound modality system 16 rather than at the physiology workstation 10. Although the physiology procedure is initiated at the ultrasound modality system 16, it should be understood that the procedure could also be initiated at either the x-ray modality system 14 or any of the other modality systems 18 shown I FIG. 2.

Once the procedure has been initiated at the ultrasound modality system 16, the ultrasound modality system 16 generates a start exam notification message 38 to the physiology workstation 10. Once the physiology workstation 10 receives the start exam notification message, the physiology workstation 10 will obtain the required patient information from the server 12 and will again relay the required start exam notification messages 26 to the modality systems that are required for the physiology procedure being performed on the patient. The start exam notification messages will also be sent back to the modality system where the physiology procedure was initiated by the operator. As with the embodiment shown in FIG. 1, each of the modality systems required for the performance of the physiology procedure will automatically issue a patient info query 30 to the physiology workstation 10, which in turn will reply with the identical patient and exam information such that the physiology workstation 10 and each of the modality systems 14, 16 and 18 will be operating with the identical patient and exam information.

As indicated in the above description, the automatic notification of the beginning of a physiological procedure to each of the modality systems required for the procedure eliminates the requirement that each of the modality systems must be manually initiated for the performance of a physiology procedure. The automatic notification to each of the modality systems from the physiology workstation 10 thus reduces the amount of time required to begin the procedure while also reducing the potential of user data entry errors. The reduction in time and increased accuracy increases the procedural efficiency to start the exam/study, particularly where the exam/study utilizes multiple modality systems. Further, each of the modalities are configured such that once each modality receives the start exam notification message, the modality is auto-triggered to request and exchange the patient information of the current patient undergoing the procedure such that all of the modalities receive the identical patient information. The synchronization between the patient information among the different modalities ensures that the monitoring data received at the physiology workstation 10 can be correctly correlated to a single patient, thus reducing errors associated with prior systems.
