Status and influencing factors on accuracy of estimation in applying Richmond Agitation Sedation Scale by nurses of Intensive Care Unit

Abstract

Objective To investigate the status on accuracy of estimation in applying Richmond Agitation-Sedation Scale (RASS) by nurses of Intensive Care Unit (ICU) for sedation of critically ill patients and to explore its influencing factors. Methods From November 2016 to January 2017, we selected 206 ICU patients and 38 ICU nurses of a ClassⅢ Grade A hospital in Beijing by convenience sampling. Research group and ICU nurses respectively assessed patients' agitation-sedation state with the RASS and analyzed its differences as well as influencing factors. Results There were 143 patients assessed by ICU nurses with the RASS in accordance with that in research group with 69.4% for the accuracy rate. Logistic regression analysis showed that the influencing factors of accuracy of estimation in RASS included sedative, score of Glasgow and delirium (OR=0.065, 1.424, 0.201; P<0.05) . Conclusions The accuracy of estimation in applying RASS by ICU nurses is at a middle level. We should pay attention to patients with sedative, delirium and the low score of Glasgow during applying RASS for critically ill patients.
