a
The Braden Scale for Predicting Pressure Sore Risk assesses a person’s risk of developing a pressure ulcer by examining six criteria: moisture, activity, mobility, nutrition and friction and shear.
b
Screening of facility residents for carbapenemase-producing bacterial colonization was performed routinely. Screening for colonization by other multidrug-resistant organisms was not performed.
CI, confidence interval; IQR, interquartile range; M, median; OR, odds ratio.
