Health Outcomes: pressure ulcer prevalence, bowel continence, and bladder continence

Outcomes	Total, n (%)	By SB type		P value*
		MMC, n (%)	Non-MMC, n (%)
Pressure ulcer prevalence†	302 (13.9)	275 (15.6)	27 (6.6)	<.0001
Pressure ulcer location
Trunk/upper extremity	28 (9.3)	27 (9.8)	1 (3.7)
Lower extremity/foot	184 (60.9)‡	162 (58.9)	22 (81.5)
Posterior pelvis/perineum	73 (24.2)§	69 (25.1)	4 (14.8)
Multiple locations—other combinations**	17 (5.6)	17 (6.2)		.1223
Continence††
Bowel continence‡‡	356 (29.7)	315 (29.7)	41 (29.1)	.92

^*P value for difference between type of SB (MMC vs non-MMC).

^†Total sample N = 2172; MMC = 1763, Non-MMC = 409; 302 reflects 277 participants who had a single pressure ulcer and 25 who had 2–3 pressure ulcers.

^‡Participants had pressure ulcers on both lower extremity and foot.

^§Four participants had pressure ulcers on both posterior pelvis and perineum.

^**A total of 17 participants had 2–3 pressure ulcers reflecting other combinations; 8 on trunk + foot or posterior pelvis; 7 on foot + posterior pelvis or other; 2 on the lower extremity + posterior pelvis or head.

^††Defined as continence during the day for those who have impaired bowel or bladder function.

^‡‡Subsample of participants age 5 and older with impaired bowel function; total n = 1200; MMC 1059; non-MMC = 141 (Table I).

^§§Subsample of participants age 5 and older with impaired bladder function; total n = 1299; MMC 1133; non-MMC = 166 (Table I).
