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)

From: 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

  Interventional period (n = 34) Control period (n = 14) p value
Pre-analytical TAT
From admission to screening (h) 11.6 (IQR 2.0–21.8) 6.2 (IQR 3.2–33.3) 0.759
Analytical TAT
From screening to arrival in the laboratory (h) 2.5 (IQR 1.5–11.3) 6.4 (IQR 2.3–19.0) 0.189
From receipt to result notification (h)a 2.6 (IQR 2.1–28.8) 40.4 (IQR 29.3–73.7)  < 0.001
Post-analytical TAT
From result notification to CP discontinuation (h)a,b 24.0 (IQR 5.7–32.8) 17.4 (IQR 9.1–30.5) 0.56
Total TAT
From admission to CP discontinuation (h) 43.4 (IQR 27.0–92.0) 67.4 (IQR 34.7–84.6) 0.29
From admission to result notification (h)a 22.1 (IQR 12.3–55.2) 61.9 (IQR 56.7–105.0)  < 0.001
  1. aExcluding 2 patients in the interventional period with missing date of results
  2. bExcluding 3 and 5 patients in the interventional and control period with CP discontinued before results notification
