Table 1 SWALIS modified Italian Government urgency related groups (URGs)

From: A model to prioritize access to elective surgery on the basis of clinical urgency and waiting time

URG Clinical assessment MTBT
A1 Evident fast progression of disease affecting outcome by delay (SWALIS) 8 days
A2 Potential fast progression of disease affecting outcome by delay 30 days
B Severe pain and/or dysfunction and/or disability, but no fast progression of disease affecting outcome by delay 60 days
C Mild pain and/or dysfunction and/or disability, but no fast progression of disease affecting outcome by delay 180 days
D No pain, dysfunction and disability and no fast progression of disease affecting outcome by delay 360 days
  1. Italian Government definition of four urgency-related groups (URG) based on the presence of the fast progression of disease (A) and on the grading of pain, dysfunction and disability (B, C, D). Each URG is associated with the respective Maximum Time Before Treatment (MTBT) as indicated in the right column. The SWALIS scientific committee adopted URGs' minor modification, dividing URG A (presence of fast progression of disease affecting outcome by delay, MTBT 30 days) into A1 and A2, by the further definition in case the disease progression was evident (8 days) or potential (30 days), respectively.
