PB2277: ANALYSIS ON POLLUTION STATUS AND INFLUENCING FACTORS OF NURSES’ UNIFORMS IN HEMATOLOGY GENERAL WARD

Abstract

Background: In clinical work, nurses are the direct caregivers of patients, and they need to cooperate with doctors to observe patients’ conditions and carry out a number of clinical operations. Therefore, the contamination of nurses’ uniforms should be taken into account by hospital infection control workers. Contaminated nurses’ uniforms will reduce the quality of nursing and affect the treatment and rehabilitation of diseases, especially the hematological tumors patients who with low immunity. According to the study, nurses should change cleaning. Aims: Investigate and analyze the contamination of nurses’ uniforms after different working hours in hematology general ward, in order to providing some references to improve the quality of hospital infection management. Methods: From July to November 2021, front-line clinical nurses in the hematology general ward of a tertiary hospital in Chongqing were selected as the research objects by convenience sampling method. Samples were taken from different parts of the nurse at 8 different times, which including when changing clean uniform, and 1h, 3h, 6h, 2d, 3d, 4d and 5d after changing clean uniforms. Results: In this study, a total of 264 qualified specimens were collected from 33 nurses’ uniforms. Descriptive analysis showed that the bacterial colony counts of cuff, abdomen and front chest at the 6th hour after changing clean uniforms were (11.30±3.56) CFU/cm2, (8.79±2.33) CFU/cm2, and (11.06±2.71)CFU/cm2 and the qualified rates of cleanliness were 0, 9.1% and 3.0% respectively. Multiple linear regression analysis showed that, at the 6th hour after changing clean uniforms, the main influence factors of the bacterial colony count on the cuffs were work times, environmental humidity and the height of nurse, the fore chests were work times and the height of nurse, and the abdomens were work times, the total number of patients and the number of first-grade patients (all P<0.05). After 5 days, the main influence factors of the bacterial colony count on the cuffs were work times and the total number of patients, the fore chests were work times and the height of nurse, and the abdomens were work times and the total number of patients (all P<0.05). Summary/Conclusion: It is necessary for nurses in general hematology department to increase the frequency of changing nurses’ uniforms and improve the cleanliness to ensure the nursing quality and patient safety. For nursing managers, it is essential to optimize the allocation of human resources further and provide necessary infection protection equipment to reduce the risk of hospital-acquired infection caused by the serious pollution of nurses’ work clothes.
