Background  The prognosis of acute limb ischemia is severe, with amputation rates of up to 25% and in-hospital mortality of 9-15%. Delay in treatment increases the risk of major amputation and may be present at different stages, including patient delay, doctors´ delay and waiting time in the emergency department. It is important to identify existing problems in order to reduce time delay.  The aim of this study was to collect data for patients with acute limb ischemia and to evaluate the time delay between the different events from onset of symptoms to specialist evaluation and further treatment with focus on pre-hospital and in-hospital time delays.    Methods  We conducted a prospective cross-sectional cohort study including all patients suspected with acute limb ischemia who were admitted to the emergency department of a community hospital in a six months period. Temporal delay in the different phases between the time of occurrence of symptoms and completion of treatment was recorded prospectively. All patients who underwent intervention had a 30 days follow-up with regard to major amputation of the leg and survival.    Results  A total of 42 patients (21 men and 21 women) age 73 (20–95) years (median (range)) was identified.  From onset of symptoms to first contact with a doctor the time for all patients were 24 (0–1200) hours. Thirty patients needed immediate intervention. In the group of fourteen patients who had immediate operation, the median time from vascular evaluation to revascularization was 324.5 (122–873) minutes and in the group of eight patients that went through an imaging procedure before an operation the median delay was 822 (494–1185) minutes from specialist assessment to revascularization. The median time for revascularization among four patients, who were treated with arterial thrombolysis was 5621 (1686–8376) minutes.  At 30 days follow up, six patients had had the ischemic limb amputated above the ankle and four patients had died.    Conclusions  We found that the largest time delay was between onset of symptoms and first contact to a medical doctor. A greater public awareness is needed, so as to facilitate urgent revascularisation and improve outcomes.
