“…Study designs included before and after implementation studies (n = 3) [10, 20, 23], retrospective observational (n = 6) [11-13, 16, 18, 21] and prospective interventional studies (n = 5) [14,15,17,19,22]. The majority of studies were conducted in Europe (n = 5) [13,17,19,20,22] or North America (n = 8 )[10-12, 14-16, 18, 23] with one paper from Australia [21]. Half of the included papers studied perioperative patient populations (50%, n = 7) [10,11,13,15,19,21,41], while 7% (n = 1) were focused on critical care [23], and 43% (n = 6) were unspecified [12,14,[16][17][18]20].…”
