Logistic analysis of factors influencing the overtime of turnaround time before the testing of the urine culture specimens in ICU.

Factors of ICU	Time out group (n = 58)	Not time out group (n = 6)	Multivariate analysis
	Pre-TAT > 115 min	Pre-TAT ≤ 115 min	B	P	OR (CI)
Number of collection nurses C, n	25	4	3.19	0.00**	24.33 (5.18–114.13)
Number of collection time D, n	33	2	4.86	0.00**	128.59 (23.43–71.63)a

Pre-TAT, pre-analytical turnaround time; Collect nurses C, 6 specimen sampling personnel in the ICU; Collection time D, Specimen sampling time within 4:00–5:59 or 10:00–11:59.

^a Firth's penalized likelihood regression confirmed the extreme OR magnitude (OR = 85.40, 95%CI: 18.25–399.55, P < 0.001).

^**P < 0.01.
