An interventional quasi-experimental study to evaluate the impact of a rapid screening strategy in improving control of nosocomial extended-spectrum beta-lactamase-producing Enterobacterales and carbapenemase-producing organisms in critically ill patients

Table 3 Laboratory turn-around times among patients at-risk with unnecessary contact precautions and actionable results (excluding patients at a high risk of carriage and patients screened during holidays)

	Interventional period (n = 34)	Control period (n = 14)	p value
Pre-analytical TAT
