title: Workflow optimization in vertebrobasilar occlusion.
abstract: OBJECTIVE
  In vertebrobasilar occlusion, rapid recanalization is the only substantial means to improve the prognosis. We introduced a standard operating procedure (SOP) for interventional therapy to analyze the effects on interdisciplinary time management.
  
  
  METHODS
  Intrahospital time periods between hospital admission and neuroradiological intervention were retrospectively analyzed, together with the patients' outcome, before (n=18) and after (n=20) implementation of the SOP.
  
  
  RESULTS
  After implementation of the SOP, we observed statistically significant improvement of postinterventional patient neurological status (p=0.017). In addition, we found a decrease of 5:33 h for the mean time period from hospital admission until neuroradiological intervention. The recanalization rate increased from 72.2% to 80% after implementation of the SOP.
  
  
  CONCLUSIONS
  Our results underscore the relevance of SOP implementation and analysis of time management for clinical workflow optimization. Both may trigger awareness for the need of efficient interdisciplinary time management. This could be an explanation for the decreased time periods and improved postinterventional patient status after SOP implementation.
