DOT variance due to ENT resources nurse participation. Bar graph representing the mean values of DOT among group with and without ENT resource nurse participation. Without an ENT nurse (Group A) cases finished on average 4.34 min late (M = 4.34, SE = 0.51). With an ENT nurse (Group B) cases finished on average 2.75 min early (M = − 2.75, SE = 0.59). Standard Error (SE) was derived by using the formula, standard deviation (SD)/square root of total number of samples (√n)
