Analysis of risk factors of pressure ulcer healing / 中国实用护理杂志

ABSTRACT

Objective To investigate the risk factors of wound healing 30 days after treatment in patients with pressure ulcer. Methods Two hundred and forty-five hospitalized patients with pressure ulcer between January 2015 and October 2016 were selected. They were divided into the healed group and the unhealed group 30 days after the treatment. The influencing factors 13 indexes including age, gender, edema, the number of diseases, the number of pressure ulcer, the size of pressure ulcer, PUSH score (Pressure Ulcer Scale Healing), hemoglobin, serum albumin, low density lipoprotein cholesterol and blood homocysteine underwent single factor and Logistic regression analysis. Results Single factor analysis of 12 indicators of risk factors affecting healing were age, Hb, Alb, Hcy, area of ulcer and PUSH scores of the 6 indicators in the regression equation (Z=3.11-6.63, All P < 0.01), gender also entered the regression equation (χ2=0.19, P<0.01);further multivariate regression analysis showed that there were statistically significant differences in PUSH score index (χ2=10.47, P<0.01, OR=0.001, 95%confidence interval were 0.001-0.037). Conclusions Age, gender, Hb, Alb, Hcy and PU area were the risk factors of pressure ulcer healing.
