From mothership to drip-and-ship: Effects of staff shortages at a comprehensive stroke center

Abstract

Background: Mechanical thrombectomy (MT) has been shown to be effective in the acute phase of ischemic stroke. Current data suggests that the drip-and-ship and mothership telestroke models are equally effective for its administration. We describe the consequences of changing the telestroke model due to staff shortages in a comprehensive stroke center (Besançon), which was replaced by a more distant one (Dijon).

Methods: We conducted a retrospective analysis of all patients referred for MT from January 2015 to December 2018. We analyzed the time between symptom onset and arrival in the angiography suite. We also calculated number of thrombectomies divided by number of days on call, and rate of thrombectomies relative to the number of strokes in each group.

Results: In Besançon, 205 patients underwent an MT procedure, versus 43 patients in Dijon. A further four patients were transferred to Dijon but not treated. The time from symptom onset to arrival in the angiography suite was longer for Dijon; 334min versus 281min for Besançon (p<0.001). The percentage of thrombectomies performed per day on call was higher for Besançon: 18.6% versus 13.2% in Dijon (p=0.026).

Conclusions: Over the study period, the time from symptom onset to angiography suite was longer for patients who were transferred to Dijon. The period in which the Besançon hospital experienced the greatest lack of personnel corresponded to a decrease in the number of MTs performed.
