Exploring bacterial growth and recolonization after preoperative hand disinfection and surgery between operating room nurses and non-health care workers: a pilot study

Table 2 Bacterial growth and recolonization at three culture sites on the hands of operating room nurses and non-health care workers after preoperative hand disinfection and after wearing surgical gloves

	Culture	Operating room nurses n = 12				Non-health care workers n = 13				P-value
	Culture	N (%) growth	CFU/mL mean	CFU/mL median	CFU/mL IQR	N (%) growth	CFU/mL mean	CFU/mL median	CFU/mL IQR	P-value
After hand disinfection	Palm	5 (41.7)	13	0	18	1 (7.7)	0.8	0	0	0.044 ^*
	Finger	6 (50.0)	14	5	18	1 (7.7)	0.8	0	0	0.019 ^*
	Nail	8 (66.7)	28	10	65	5 (38.5)	52	0	40	0.434
After wearing gloves	Palm	4 (33.3)	18	0	8	3 (23.1)	29	0	5	0.893
	Finger	4 (33.3)	98	0	10	0	0	0	5	0.039 ^*
	Nail	10 (83.3)	244	55	463	12 (92.3)	1554	780	2940	0.016 ^*

Mann-Whitney U Test was used to calculate the numbers of bacterial differences at the different culture sites in CFU/mL between the groups
IQR interquartile range
^*Statistically significant difference. Entries in bold face represent significantly more bacterial growth and its relationship with the significance in P-value
