Failure mode and effects analysis on the control effect of multi-drug-resistant bacteria in ICU patients

Objective: The failure mode and effect analysis of the prevention and control in intensive care unit (ICU) patients with multi-drug-resistant (MDR) bacterial infection were explored and analyzed in this research.

Methods: A total of 251 critically ill patients who were hospitalized in the ICU from June to December 2019 were selected as the control group, and another 258 patients who were hospitalized in the ICU from January to June 2020 were set as the observation group. The control-group patients received conventional ICU care, the observation group was treated by the failure mode and effects analysis (FMEA), and then the prevention and control effect of the two nursing modes on multi-drug-resistant bacteria infection in the two groups were compared accordingly.

Results: The RPN values of the five highest-level factors in the nursing process were critically lower after the improved interventions than before the improvement. The infection rate of MDR bacteria in the observation group was obviously lower than that in the control group (14.73%, 26.69%, χ² =11.1233, P=0.0009). In addition, the mortality rate of patients with MDR in the observation group was remarkably lower than that in the control group, and the difference was statistically significant (5.26%, 22.39%, χ² =5.2405, P=0.0221). The satisfaction of the observation group with the ICU treatment was critically higher than that of the control group, and the difference was statistically significant (89.53%, 76.49%, χ² =15.4094, P=0.0001).

Conclusion: Through the application of FMEA to prevent MDR bacterial infection in ICU patients, nursing staff can accurately pay attention to the keynotes in nursing process, and as such reduce the proportion and mortality of MDR infection in ICU patients and promote the patients' satisfaction with nursing, which are all worthy of clinical application.
