Impact of a Standardized Alarming System on Treatment Times and Workflow in Stroke Patients With Interhospital Transfer for Thrombectomy

Recruiting

• Conditions: Acute Ischemic Stroke

• Registration Number: NCT05963685
• Lead Sponsor: Munich Municipal Hospital

Brief Summary

The aim of this study is to evaluate the impact of a standardized alarming system on treatment times and workflow in stroke patients with interhospital transfer for mechanical thrombectomy (MT). The main questions it aims to answer are:

* Is the implementation of a standardized alarming system associated with shorter transfer and treatment times?

* Is the implementation of a standardized alarming system associated with a better adherence on existing standard operating procedures for interhospital transfer? We will analyze data from our existing thrombectomy registry comparing time periods before and after introduction of the MT alarming system.
