Analysis of Factors Causing Skin Damage in the Application of Peripherally Inserted Central Catheter in Cancer Patients

Table 3

Results of binary logistic regression analysis on whether skin injury occurred during PICC catheterization.

	Regression coefficient	Standard error	Wald value		OR value	OR value 95% confidence interval
						Lower limit	Upper limit
Constant	−5.780	2.274	6.463	0.011	0.003	—	—
Whether or not use of hormones (yes)	1.360	0.679	4.012	0.045	3.896	1.030	14.743
BMI	0.122	0.051	5.651	0.017	1.129	1.022	1.249
Days with tube	−0.870	0.352	6.126	0.013	0.419	0.210	0.834
Chemotherapy cycle (≥IV stage)	1.109	0.504	4.848	0.028	3.032	1.130	8.139

Only the independent variables with are shown. The accuracy of these variables in predicting skin injury was 81.7%. ‘OR Value’ (odd ratio value) is the ratio index to measure the effect of risk factors. Wald is a chi square value and it is equal to B divided by the square of its standard error (S.E.).
