Development and validation of a postoperative delirium prediction model for patients admitted to an intensive care unit in China: a prospective study.


ABSTRACT: OBJECTIVES:We aimed to develop and validate a postoperative delirium (POD) prediction model for patients admitted to the intensive care unit (ICU). DESIGN:A prospective study was conducted. SETTING:The study was conducted in the surgical, cardiovascular surgical and trauma surgical ICUs of an affiliated hospital of a medical university in Heilongjiang Province, China. PARTICIPANTS:This study included 400 patients (?18 years old) admitted to the ICU after surgery. PRIMARY AND SECONDARY OUTCOME MEASURES:The primary outcome measure was POD assessment during ICU stay. RESULTS:The model was developed using 300 consecutive ICU patients and was validated using 100 patients from the same ICUs. The model was based on five risk factors: Physiological and Operative Severity Score for the enumeration of Mortality and morbidity; acid-base disturbance and history of coma, diabetes or hypertension. The model had an area under the receiver operating characteristics curve of 0.852 (95% CI 0.802 to 0.902), Youden index of 0.5789, sensitivity of 70.73% and specificity of 87.16%. The Hosmer-Lemeshow goodness of fit was 5.203 (p=0.736). At a cutoff value of 24.5%, the sensitivity and specificity were 71% and 69%, respectively. CONCLUSIONS:The model, which used readily available data, exhibited high predictive value regarding risk of ICU-POD at admission. Use of this model may facilitate better implementation of preventive treatments and nursing measures.
