Application of health care failure mode and effects analysis to reduce the paediatric wards noise pollution / 中国实用护理杂志

ABSTRACT

Objective:To use the methods of Health Care Failure Mode and Effects Analysis to reduce the paediatric wards noise pollution, Ensure the physical and mental health of medical staff and children, and maintain a good medical environment.Methods:The sampling method is adopted, noise investigation questionnaire was used in our study and we use the noise instrument to monitor the sound, and the focus source, the key time period and the key section of the room noise are obtained, then the HFMEA is carried out, we listed the work flow of the pediatric ward, and the flow is analyzed and discussed, calculate the Risk Priority Number (RPN). Then, some improvement measures were carried out aimed at the failure mode ,the noise survey questionnaire were used for evaluation.Results:After the implemented the HFMEA , The RPN value was significantly decreased ( P < 0.05). the degree of noise interference of children and their families decreased from 38 to 29, the difference was statistically significant ( χ2 value was 21.82, P<0.05) , and the satisfaction with control noise was improved from 18 to 30, the difference was statistically significant ( χ2 value was 36.28, P<0.05) .The intensity of noise key areas, The intensity of noise source and intensity in each period of the day were significantly improved and the difference was statistically significant ( P < 0.05), and the critical value was significantly decreased. Conclusion:Applying HFMEA can reduce ward noise pollution, improve patient satisfaction, ensure the physical and mental health of medical staff and children, and create a good medical environment.
