“…The VAS and the NRS have both been evaluated for use in the ED (Bahreini, Jalili, & Moradi-Lakeh, 2015;Bijur, Latimer, & Gallagher, 2003;Bijur, Silver, & Gallagher, 2001;Göransson, Heilborn, & Djarv, 2016;Williamson & Hoggart, 2005). The NRS is easier to use since no equipment is needed and, therefore, it might be more suitable to use in the ED (Göransson et al, 2016;Williamson & Hoggart, 2005). The choice between the VAS and the NRS can therefore be based on subjective preferences (Breivik, Bjornsson, & Skovlund, 2000).…”
