Abstract:
Objective:To explore the effect of DMAIC(Define, Measure, Analyze, Improve, Control) in reducing catheter-related urinary tract infection.
Methods:A retrospective case control method was used to select 578 patients admitted and treated in comprehensive ICU of Tianjin First Central Hospital from January to December 2018 with catheters as research objects.The 283 patients from January to June 2018 were the control group, and 295 patients from July to December 2018 were the observation group.Routine methods were used in the control group, and DMAIC method with 6 sigma management was used in the observation group. The correct rate of implementation of each measure, the utilization rate of urinary catheter and the infection rate between the two groups were compared.
Results:Implementation rate of early extubation assessment, urine collection accuracy, urine tube fixed correctly, urine tube cleaning time, urine collection bags location accuracy were 60.42%(171/283), 69.61%(197/283), 79.86%(226/283), 89.40%(253/283), 92.58%(262/283)in the control group, 80.34%(237/295), 90.85%(268/295), 94.92%(280/295), 96.27%(284/295), 97.97%(289/295) in the observation group, the differences were statistically significant (χ2= 9.411-41.415, P < 0.01). The rate of urinary catheter usage was 75.31%(3 856/5 120) in the observation group and 82.60%(4 098/4 961) in the control group, the differences was statistically significant (χ2=80.475, P < 0.01). The rate of catheter associated urinary tract infection was 0.26‰ (1/3 856) in the observation group and 1.95 ‰ (8/4 098) in the control group, the differences was statistically significant (χ2=5.832, P< 0.05).
Conclusions:DMAIC can improve the accuracy of nursing measures, optimize the catheter care process, and reduce catheter-related urinary tract infections.
