Investigation on the knowledge and influencing factors of vessel catheter-associated infection among clinical nurses
Objective To investigate the current situation of clinical nurses'knowledge of vessel catheter-associated infection(VC AI)and analyze its influencing factors,so as to provide a basis for homogenizing training on prevention and control strategies of VC AI.Methods A total of 1 450 nurses were selected from 15 hospitals in East,West,Central,South and North area of China from April 9 to June 9 2022 by multi-stage random sampling method.They were investigated by general data questionnaire and VC AI knowledge questionnaire.The questionnaire included 7 dimensions,covering definition,clinical manifestations,diagnosis methods,risk factors,prevention measures,treatment measures and management system.Results A total of 1 424 valid questionnaires were collected,with an effective recovery rate of 98.21%.Nurses'knowledge of VCAI was 50.97±19.20.There were 442 qualified nurses(30.9%),169 good nurses(11.8%),and 50 excellent nurses(3.5%).Multiple linear regression analysis showed that the main influencing factors of clinical nurses'knowledge score on VCAI were age,hospital grade,job post,educational background,and whether or not they were intravenous therapy specialist nurses(P<0.05).Conclusion Nurses in county-level and prefecture-level hospitals who participated in the survey had a lower knowledge of VCAI than nurses in provincial or minister-level hospitals.Nursing managers should conduct homogenized training on VCAI knowledge for nurses in county-level and prefecture-level hospitals,so as to change the prevention and treatment behavior of nurses in county-level and prefecture-level hospitals,and reduce the incidence of VCAI.
