Objectives: We intended to map the geographical distribution of patients with acute stroke who called the Tehran EMS center based on the geographic information of the incident location on a map. The distributions of these centers and patients access within a standard period were evaluated.
Methods: A cross-sectional study based on the registered data was conducted on suspected acute stroke patients > 18 years of age that were transferred by EMS. The analysis was performed based on pointing the patients locations and locating the hospitals in ArcGIS software plus a review of the polygons and focal points.
Results: Totally, 1,606 patients suspected to stroke with a mean age of 64.89 ± 17.48 years were evaluated, of whom 947 (58.6%) were
male. The mean time of arrival of an ambulance in the patients location from the EMS station was 11.94 ± 6.67 minutes, and the longest time was 69.32 minutes. The mean time from the patients location to the stroke center was 17.79 ± 11.42 minutes (range 2.4 - 83.70 minutes). Stroke centers in Tehran are not distributed in a balanced manner, and they are concentrated on the central and northern parts of Tehran, limiting access to hospital services.
Conclusions: The multiplicity of hospitals in the west and center of Tehran led to an increase in access times in eastern Tehran. It
emphasizes the necessity of revision of service locating, especially because the east of Tehran has a denser texture than the west.
