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.

Conditions

Acute Ischemic Stroke

Keywords

mechanical thrombectomy, telestroke, drip and ship, interhospital transfer, communication

Outcome Measures

Primary Outcomes (1)

• decision-to-groin time

  time from decision for MT (while patient still in the primary stroke center) to groin puncture (start of mechanical thrombectomy procedure in the primary thrombectomy center)

  24 hours

Secondary Outcomes (9)

• decision-to-departure time

  24 hours

• decision-to-arrival time

  24 hours

• arrival-to-groin time

  24 hours

• rate of refusal of transfer requests due to lack of capacity

  24 hours

• decision-to-transfer request time

  24 hours

Study Arms (3)

pre implementation period

stroke patients transferred within the 6 months before introduction of the alarming system

implementation period

stroke patients transferred within the 6 months after introduction of the alarming system

Other: standardized MT alarming system

post implementation period

stroke patients transferred within the 6-12 months after introduction of the alarming system

Other: standardized MT alarming system

Interventions

standardized MT alarming system OTHER

Standardized alarming system via telephone loop in the primary thrombectomy centre triggered immediately after decision to mechanical thrombectomy in stroke patients admitted in primary stroke centers

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

Study Population

Acute ischemic stroke patients admitted to one of 7 nonurban primary stroke centers with subsequent interhospital transfer to a referral center for mechanical thrombectomy in Southeast Bavaria, Germany.

You may qualify if:

• age \>= 18 years
• diagnosis of acute ischemic stroke
• indication for mechanical thrombectomy
• admission to one of 7 participating primary stroke centers within in the catchment area of the referral center

You may not qualify if:

• unclear indication for mechanical thrombectomy (patients admitted for perfusion imaging before decision for or against a MT)
