“…Implementation of standardized protocols has improved pain management for various surgical procedures and clinical settings as shown in studies using preintervention/postintervention measurements [ 2 , 5 , 6 , 14 , 15 , 18 , 27 , 32 , 35 ]. Standardized protocols seem to be pivotal elements in the management of acute and postoperative pain, especially when a dedicated APS is not readily available [ 13 , 22 ]; however, these investigations were not based on a single intervention or randomized controlled trials, but reflect a whole range of procedural and structural changes [ 2 , 5 , 6 , 14 , 15 , 18 , 27 , 32 , 35 ]. Thus, a multifactorial mix of effects likely contributes to the improvements demonstrated in these studies.…”
