From: Pre-hospital delay in patients with first time myocardial infarction: an observational study in a northern Swedish population

Characteristic Total prehospital delay ≥ 2 h Decision time ≥ 2 h
Adjusted OR (95 % CI) P-value Adjusted OR (95 % CI) P-value
Personal visit to a GP before referral 10.77 (2.39–48.59) 0.002 3.85 (1.66–8.90) 0.002
Referred by call to a primary care centre/Swedish Healthcare Direct 3.82 (1.68–8.68) 0.001 2.00 (1.03–3.87) 0.041
Chest pain predominating symptom at triage 0.24 (0.08–0.77) 0.016 0.34 (0.12–0.90) 0.031
Distance to hospital, km 1.03 (1.02–1.04) <0.001 1.00 (1.00–1.01) 0.586
  1. Total pre-hospital delay is the time between onset of symptoms suggestive of myocardial infarction and admission to the hospital. Decision time is the time between onset of symptoms suggestive of myocardial infarction and the call to Emergency Medical Services
