Workflow analysis has the potential to dramatically improve the efficiency and clinical outcomes of medical procedures.
In this study, we recorded the workflow for nerve block and facet block procedures in the interventional radiology suite
at Georgetown University Hospital in Washington, DC, USA. We employed a custom client/server software architecture
developed by the Innovation Center for Computer Assisted Surgery (ICCAS) at the University of Leipzig, Germany.
This software runs in an internet browser, and allows the user to record the actions taken by the physician during a
procedure. The data recorded during the procedure is stored as an XML document, which can then be further processed.
We have successfully gathered data on a number if cases using a tablet PC, and these preliminary results show the
feasibility of using this software in an interventional radiology setting. We are currently accruing additional cases and
when more data has been collected we will analyze the workflow of these procedures to look for inefficiencies and
potential improvements.
