Shujah Das Gupta BSC, , Presenter: Nothing to Disclose

With the increasing usage of IHE profiles such as XDS and XDS-I, it is now possible to access patient healthcare records which are distributed across multiple healthcare enterprises. In order to simplify the patient identification process, a patient’s biometric data can be used for identification as opposed to the traditional ID based systems in the XDS workflow. This paper discusses the feasibility of using biometric data for cross-enterprise patient identification to simplify clinical workflows and ensure error-free patient identification.

This paper proposes the usage of BioPIX by leveraging the existing infrastructure used for implementing the XDS profile to reconcile patient ID’s. Currently, there are two ways to acquire a patient ID for executing a query to an XDS registry: Using the local patient ID if there is only one assigning authority Reconciling the patient ID through a PIX query if there are multiple assigning authorities BioPIX is useful for provider facilities which are a part of an affinity domain that uses a PIX manager for patient ID reconciliation. It proposes the use of biometric patient data to retrieve patient ID details from the PIX manager. These details can be used to aggregate the patient’s records from connected provider facilities.

BioPIX requires the following modifications to be made in the existing workflow: Install a standardized fingerprint/retinal scanner at each XDS Consumer end point. Modify the HL7 interface used for communication between the PIX Manager and PIX Consumer to allow the patient’s biometric data to be embedded in the PIX query message. Insert an additional record on the PIX manager to map the patient’s biometric data the patient on the PIX Manager The modifications listed above will enable patient ID reconciliation to occur entirely within a PIX query transaction.  

BioPIX will provide the following benefits for healthcare enterprises: Increase accuracy of patient matching Eliminate any potential human errors that may occur in patient matching Better handling of emergency cases - Allow instantaneous access to comprehensive patient records at the point of care    

BioPIX will allow simpler, safer and faster access to patient records at clinical sites without impacting existing workflows.
