A preliminary study of the effect of closed incision management with negative pressure wound therapy over high-risk incisions

Table 4 Differences in dressing changes and complications between control and NPWT groups

	Number (%)		Odds ratio
Outcome	Control (n = 10)^a	NPWT (n = 10)^b	(95 % CI)		p-value^c
Additional dressing changes required	4 (40 %)	0 (0 %)	0	(0.00 to 1.30)	0.09
Sedation required for dressing changes	2 (20 %)	2 (20 %)	1	(0.06 to 17.08))	1
Short-term complications	4 (40 %)	0 (0 %)	0	(0.00 to 1.30)	0.09
Major long-term complications^d	3 (37.5 %)	1 (12.5 %)	0.29	(0.00 to 5.49)	0.56
Wound dehiscence	1 (12.5 %)	0 (0 %)	0.0	(0.00 to 34.67)	0.47
Acute infection	0 (0 %)	0 (0 %)	-	-	-
Chronic infection	1 (12.5 %)	3 (37.5 %)	3.84	(0.23 to 250.88)	0.57

^aThere were 8 controls included in the analysis of long-term complications
^bThere were 8 NPWT patients included in the analysis of long-term complications
^cFisher’s exact test
^dPresence of long term complications are unknown for 2 controls and 2 NPWT patients as they were lost-to-follow-up
