Objective:To understand the effect of presenteeism behavior of nurses on patient satisfaction and to explore the correlation between them.Methods:This study was a cross-sectional study. In December 2019, the convenient sampling method was adopted to select 500 in-service responsible nurses and 500 inpatients under the charge of the responsible nurses in 5 Class Ⅲ Grade A hospitals in Henan Province as the research objects. The responsible nurses were surveyed by general information questionnaire and Presenteeism Behavior Scale and patients in charge were surveyed by Inpatient Satisfaction and Experience Monitoring Scale.Results:A total of 435 valid questionnaires were collected from responsible nurses and patients in charge. The score of Presenteeism Behavior Scale of 435 nurses was (2.62±0.93) and the score of Inpatient Satisfaction and Experience Monitoring Scale of 435 patients was (4.50±0.49) , showing negative correlation ( r=-0.19, P<0.01) . Conclusions:The level of nurses' presenteeism behavior is at a moderate level and patient satisfaction is at an upper-middle level. Nurses' presenteeism behavior affects patient satisfaction. The higher the incidence of nurses' presenteeism behavior, the lower the patient satisfaction. It is recommended to reduce nurses' presenteeism behavior and improve patient satisfaction.
