Figure 1

The developed algorithm shows a series of windows on different clinical presentation of SCD patients at the EDs. In the two blocked windows, we stressed the need to assign at least a triage code yellow to SCD patients in order to give an appropriate therapy for pain control within 30 minutes from patients arrival to the EDs. The boxes for triage each code link to pages, describing the details of the related therapy as shown in Figure 2 or the info about the differential diagnosis or the literature.
