Multivariate Analysis^* of Preventive Intervention Based on Braden Scale Subscale Scores

Subscale/Intervention	DF^a	Estimate (SE^a)	Test Statistic	P Value	OR (95% CI)^a
Activity subscale^b	1	−0.19 (0.28)	0.45	0.502	0.83 (0.48, 1.43)
Sensory perception subscale^b	1	0.36 (0.23)	2.36	0.124	1.43 (0.91, 2.27)
Moisture subscale^b	1	−1.11 (0.28)	15.87	<.001	0.33 (0.19, 0.57)
Friction/Shear subscale^b	1	−0.88 (0.31)	7.93	0.005	0.42 (0.23, 0.77)
Mobility subscale^b	1	−0.65 (0.29)	4.97	0.026	0.52 (0.30, 0.93)
Moisture intervention^b	1	−0.06 (0.18)	0.12	0.728	0.94 (0.67, 1.33)
Friction-shear intervention^b,c	1	−0.46 (0.11)	16.11	<.001	0.63 (0.51, 0.79)

^a.

Abbreviation: DF = degree freedom, SE = Standard Error, OR = odds ratio, and CI = confidence interval.

^b.

Scores were derived as the mean of total across 3 days prior.

^c.

There was an overlap in the interventions that address low subscale scores (i.e. higher risk) for activity, mobility, friction-shear and sensory perception. The friction-shear intervention set on the PUPI tool incorporated all of these interventions and was therefore used for this analysis.
