Prise en charge des AVC au CHU de Bordeaux : lien entre indisponibilité de l’imagerie et délai admission-imagerie

Abstract : Introduction: rapid brain imaging after symptom onset is essential in stroke management. The impact of imaging availability on admission-to-imaging time has not yet been studied. Objective: to investigate the relationship between the unavailability of imaging tests (CT and MRI or only MRI) and the door-to-imaging time in stroke management. Method: stays for stroke in primary admission at the Bordeaux University Hospital were included. Data were obtained from the Observatoire Aquitain des AVC (ObA2) and the Service d'information radiologique, Réseau d'images et Communication (SRC) of the hospital. Analyses were stratified over 2 periods: before (period 1) and after (period 2) the implementation of the emergency department MRI on June 20, 2017. Association analyses were performed via multivariate linear regressions. Results: 3435 and 1320 stays were included in period 1 and period 2, respectively. For period 1, unavailability of imaging and MRIs specifically mean door-to-imaging time by 12.4 minutes (β = 1.17; CI [1.06; 1.29]) and 10.2 minutes (β = 1.14; CI [1.04; 1.25]) respectively. For period 2, imaging unavailability and MRI unavailability specifically were not associated with door-to-imaging time. Conclusion: unavailability of imaging is associated with an increase in door-to-imaging time, with variations depending on the structures, organizations, and processes in place.
