Summary

Objectives.

To study prehospital care process in relation to hospital outcomes in stroke-code cases first attended by 2 different levels of ambulance. To analyze factors associated with a satisfactory functional outcome at 3 months.

Methods.

Prospective multicenter observational cohort study. All stroke-code cases attended by prehospital emergency services from January 2016 to April 2022 were included. Prehospital and hospital variables were collected. The classificatory variable was type of ambulance attending (basic vs advanced life support). The main outcome variables were mortality and functional status after ischemic strokes in patients who underwent reperfusion treatment 90 days after the ischemic episode.

Results.

Out of 22 968 stroke-code activations, ischemic stroke was diagnosed in 12 467 patients (54.3%) whose functional status was good before the episode. Basic ambulances attended 93.1%; an advanced ambulance was ordered in 1.6% of the patients. Even though there were differences in patient and clinical characteristics recorded during the prehospital process, type of ambulance was not independently associated with mortality (adjusted odds ratio [aOR], 1.1; 95% CI, 0.77-1.59) or functional status at 3 months (aOR, 1.05; 95% CI, 0,72-1,47).

Conclusions.

The percentage of patient complications in stroke-code cases attended by basic ambulance teams is low. Type of ambulance responding was not associated with either mortality or functional outcome at 3 months in this study.
