[Value of APACHEIIfor predicting the nursing workload in EICU].

OBJECTIVE
To investigate the predictive value of acute physiology and chronic health evaluationII(APACHEII) for nursing workload in emergency intensive care unit (EICU).


METHODS
A retrospective cohort study was conducted. Critical patients except for trauma admitted to EICU of West China Hospital of Sichuan University from June 2012 to July 2016 were enrolled. APACHEII score and therapeutic intervention scoring system (TISS-28) score were calculated in each case. The relationship between APACHEIIscore and TISS-28 score was analyzed by correlation analysis and curve estimation.


RESULTS
A total of 1 148 patients were enrolled, including 689 male (60.0%), and age of (56±19) years old, APACHEII score was 19 (13, 25), and TISS score was 19 (13, 25). The Spearman correlation coefficient between APACHEII score and TISS-28 score was 0.849 (P < 0.001), and that among the linear model quadratic model, composite model, growth model, logarithm model, cubic model and exponential model R 2 were 0.669, 0.710, 0.792, 0.764, 0.765, 0.765, respectively (all P < 0.01), and the most suitable description for relationship between APACHEIIscore and TISS-28 score curve was cubic model. The nursing workload was significantly increased when APACHEII score ≥30, and it was decreased when APACHEII score < 30.


CONCLUSIONS
APACHEIIwas a useful score for predicting the nursing workload in EICU.
