Objective. To describe the approach to the patients with suspected sepsis in the Spanish emergency department hospitals (ED) and analyze whether there are differences according to the size of the hospital and the number of visits to the emergency room. Method. Structured survey of those responsible for the 282 public EDs that serve adults 24 hours a day, 365 days a year. It was asked about assistance and management in the emergency room in the care of patients with suspected sepsis. The results are compared according to hospital size (large ≥ 500 beds vs medium-small <500) and influx to the emergency room (discharge ≥ 200 visits / day vs medium-low <200). Results. A total of 250 Spanish EDs responded (89%). Sepsis protocols are available in 163 (65%) EDs median weekly sepsis treated ranged from 0-5 per week in 39 (71%) ED, 6-10 per week in 10 (18%), 11-15 per week in 4 (7%), and more than 15 activations per week in 3 centers (3.6%). The criteria used for sepsis diagnosis were the qSOFA/SOFA in 105 (63.6%) of the hospitals, SIRS in 6 (3.6%), while in 49 (29.7%) they used both criteria simultaneously. In 79 centers, the sepsis diagnosis was computerized, and in 56 there were tools to help decision-making. 48% (79 of 163) of the EDs had data on bundles compliance. In 61% (99 of 163) of EDs there was training in sepsis and in 56% (55 of 99) it was periodic. Considering the size of the hospital, large hospitals participated more frequently as recipients of patients with sepsis and had an infectious, sepsis and short-stay unit, a microbiologist and infectious disease specialist on duty. Conclusion. Most EDs have sepsis protocols, but there is room for improvement. The computerization and development of alerts for diagnosis and treatment still have a long way to go in EDs.
