Abstract

Objective: Zhejiang Province, a third B General Hospital internal medicine ward nurses station noise measurements, analysis of the noise exposure of the internal medicine ward nurses station the status quo and the main impact factors proposed reasonable interventions and to evaluate the effectiveness of the intervention of the ambient noise, provide some theoretical basis and reference for care managers and researchers in the nursing work environment management. Methods: The study is based on three B General Hospital internal medicine ward nurses station for the study, randomly selected from a medical ward in July 2010 in Zhejiang Province, a third B hospital, Hangzhou Institute of Electronic Engineering electromechanical the Plant production of HE5624A of noise statistics analyzer, the noise measuring the nurses station's various, and 72h monitoring nurses station ambient noise and nurses working conditions and events causes a sudden change of the noise analysis of noise exposure status quo and its main influencing factors, and, according to establish interventions; implementation of interventions, four weeks later, in September 2010 by the same way again measure and record the vertical comparison of the differences before and after intervention. Data entry and statistical analysis using SPSS 11.5 statistical software, specific statistical methods for descriptive statistical analysis methods and group design samples t-test, P lt; 0.05 considered statistically significant differences. Results: 1 intervention before the nurses station patient call system, dot matrix printers, phones ringing more than 70 dB (A) up to 86.5 dB (A) after the intervention significantly reduced; conversation sound, near the ward door slamming in after the intervention than before the intervention to reduce; walking sound, the sound of the wheels of the vehicle is relatively low, was not changed significantly before and after the intervention. 2 intervention before nurses station ambient noise indicators (daytime and nighttime equivalent sound level (Leq) were 64.39 ± 5.66 dB (A), and 52.64 ± 7.67 dB (A), the night sound level (Lmax) 81.53 ± 7.83 dB (A)) are far greater than the WHO and China to develop hospital ambient noise standards. Before and after the intervention the nurses station daytime noise index (Leq, Lmax, Lmin, L10, L50, L90) were higher than at night, and the difference was statistically significant (P lt; 0.05). 4, after the intervention of the nurses station noise indicators, in addition to the daytime maximum sound level (Lmax) is slightly higher than outside, the other indexes have different degrees of reduction. Daytime and nighttime equivalent sound level (Leq), the night the most the whisper level (Lmin), daytime and nighttime cumulative percentile sound level (L10) five indicators after the intervention than before the intervention significantly reduce the difference statistically significant (P lt; 0.05). Conclusion: the internal medicine ward nurses station ambient noise far exceeds the WHO and China to develop hospital ambient noise standards. Through the education and training of health care workers and behavior intervention, equipment and facilities management and environmental improvement, can effectively reduce the noise level in the nursing work environment and help to improve the quality of nursing care and nurses quality of life. And there are still some deficiencies and limitations, such as geographical study, hospital level and specialist restrictions intervention study of other influencing factors related to environmental noise, noise interfere with the effectiveness of the track for a long time. Therefore, further study of the role of noise intervention in the care and management of ambient noise.
