Stroke is one of the diseases with the highest burden of mortality and disability both in the world. There is still little evidence about the factors that affect the timeliness or delay of prehospital care services for the care of acute stroke cases. The objective of this study is to determine which factors influence the timeliness of prehospital care for patients with suspected acute stroke, provided by a public care system. An observational, analytical, cross-sectional study was carried out that analysed a secondary database of prehospital care provided by the Mobile Emergency Care System - SAMU in Lima, Peru between January 2018 and December 2019. The result variables were: response time, time on scene, transport time and the total time of care. The explanatory variables were: patient age, patient sex, ambulance dispatch diagnosis, place of care, time of call, day of week, season, workload in the previous hour and average hospital delay of the ambulance in the day. A multivariate analysis was performed for each result variable using the generalized linear model (Poisson family) and the quantile regression model, to identify the factors associated with opportunity.
