ABSTRACT
Objective:To evaluate the application effect of the nurse-led catheter extraction assessment model for children in PICU.Methods:From January to May 2020, 100 children with short-term catheter in PICU of Guangzhou Women and Children Medical Center were selected by convenient sampling method as the experimental group, the need for urethral catheter indwelling was assessed daily using an evidence-based assessment scale in PICU children, and the unnecessary indwelling catheters were removed timely, and 109 children with indwelling urethral catheters from August to December 2019 were collected as the control group, the catheter was removed by the nurse on medical advice, recorded and compared days of indwelling of catheters, the incidence of patients with catheter-associated urinary tract infection , resetting of catheters and the length of stay in ICU between the two groups.Results:The median and interquartile spacing of the days with indwelling catheter were 5.0 (6.0) days in the experimental group and 6.0 (6.0) days in the control group ( Z=-2.01, P<0.05) . In the experimental group, the incidence of catheter-associated urinary tract infection was 1.000 percent (1/100), and in the control group, the incidence of catheter-associated urinary tract infection was 1.835 percent (2/109); in the experimental group, 2 cases of urethral catheter were reset, and in the control group, 2 cases of urethral catheter were reset; the median and interquartile spacing of the length of stay in ICU was 6.5 (7.0) days in the experimental group and 7.0 (8.0) days in the control group. The differences of the above three indexes between the two groups were statistically significant ( χ2=0.26, 0.01, Z=-0.96, all P>0.05). Conclusions:The nurse-led catheter extraction assessment model for children can effectively shorten the catheter indwelling days for children in PICU, which has certain clinical practice significance for reducing the incidence of catheter-associated urinary tract infection.
