Extending the Patient Synchronized Applications Profile with Tools for Distributed Diagnosis

  1. 1. EXTENDING THE PATIENT SYNCHRONIZED APPLICATIONS PROFILE WITH TOOLSFOR DISTRIBUTED DIAGNOSIS<br />Harald Köstinger, Thomas Grechenig, Klaus Bayrhammer, Michael Fiedler, Wolfgang Schramm<br />Vienna University of Technology<br />Research Group for Industrial Software (INSO)<br />
  2. 2. Motivation<br />modern Hospital Information Systems (HIS) consist of various clinical and administrative software packages to enable as seamless as possible workflows.<br />many workflows require the utilization of different software applications by the same professional.<br />the professional has to select the same patient in each clinical or administrative application.<br />
  3. 3. Goals<br /> create a software component in background could reduce the risk of erroneous documentation by accidentally selecting the wrong patient and the time needed for the manual selection process<br />The IHE PSA Profile already provides the necessary mechanisms for this!<br /> create a software component which enables additional workflows on the basis of the PSA profile.<br />
  4. 4. Patient Synchronized Application (PSA)<br />is an existing IHE (Integrating the Healthcare Enterprise) Profile<br />enhances the quality and supports the clinical work with EHR data on e.g. workstations, radiology systems, and mobile devices<br />a PSA context manager (CM) keeps track of current selections and reduces the recurring task of selecting patients in different applications<br />applications connected to the CM get notified about the selection status<br />selecting a patient in one application causes all other running applications to select the same patient<br />
  5. 5. PSA: Architecture Overview<br />Clients within the same context (related to a signed up expert) get notified about ongoing selection changes<br />
  6. 6. PSA: Extension to the Existing Infrastructure<br />the PSA principals create the basics for the introduced Conferencing Features<br />Message Services<br />connected clients appear in a list on the CM<br />clients then can send notifications to others<br />Distributed Diagnosis<br />clients can access the list of online experts<br />experts can be invited to a distributed diagnosis of patient records<br />
  7. 7. Message Services<br />clients can send notifications to other clients<br />mainly used to forward current health care information about a certain patient<br />or to add some more information which is not part of the documentary process yet<br />allows to already brief the next doctor in the row of a clinical workflow about the next incoming patient<br />
  8. 8. Distributed Diagnosis<br />clients can invite other experts to join a distributed diagnosis session for a certain patient record/document<br />mainly used to discuss unclear findings and results with experts in certain fields<br />or when doctors need to share documents with other physicians to benefit from their knowledge<br />the invitee gets a notification and can join a read-only session on the shared document<br />a chat allows for exchanging of new findings and serves as “distributed diagnosis protocol”<br />
  9. 9. Distributed Diagnosis: The Invitation<br />Dr. Alice selects a document and invites a selected professional to a distributed diagnosis session. <br />The invitee (Dr. Bob) gets notified about this action and can decide whether to join or decline the invitation. After joining the session, a Dr. Bob gets a read-only view of the shared document and can contributed to the current treatment process via the chat protocol.<br />
  10. 10. The chat protocol allows the selection of messages which should be kept as a medical reference. Those messages are stored as part of the patient record.<br />Other messages are discarded after the session is closed.<br />The two experts have the same view on the record. Only the invitee cannot edit data – the view is read-only.<br />
  11. 11. Results and Discussion<br />our system shows how to build a PSA compliant architecture and how this can be extended by messaging services.<br />the proposed work is now part of a research HIS which is currently being developed.<br />further studies to evaluate issues in a realistic clinical IT environment have to be performed<br />
