Performance of Critical Care Outcome Prediction Models in an Intermediate Care Unit

Abstract: Background: Intermediate care units (IMCUs) are heterogeneous in design and operation, which makes comparative effectiveness studies challenging. A generalizable outcome prediction model could improve such comparisons. However, little is known about the performance of critical care outcome prediction models in the intermediate care setting. The purpose of this study is to evaluate the performance of the Acute Physiology and Chronic Health Evaluation version II (APACHE II), Simplified Acute Physiology Score ver… Show more

“…If intermediate care patients were distributed across many floors, respiratory therapy would no longer be immediately available to the 30% of IMCU admissions with respiratory insufficiency. 14 Moreover, while DOM services each carry an average of 2 to 3 intermediate care patients, this varies from day to day with no such patients on some days and more than 3 on others. On days a clinical team had no such patients, these beds would either not be used, or would be used for floor level patients.…”

“…SAPS II, an evolution of the original SAPS by Le Gall et al [ 27 ], represents a seminal advancement in critical care prognostication, with subsequent iterations culminating in SAPS III. However, empirical investigations have revealed a propensity for the SAPS III scoring schema to overestimate mortality rates among ICU patients afflicted with internal disorders when juxtaposed against its predecessor, SAPS II [ 28 ]. Of particular significance is the discernible superiority of our nomogram in predicting 28-day mortality within the ischemic stroke cohort when compared against SAPS II, an instrument encompassing a comprehensive array of 15 variables.…”

“…They use 14 or 17 variables, also making their clinical practice not convenient. SOFA, another confirmed useful predictive model of critical illness, which is much simpler than APACHE II score and SAPS II, also measures six variables (4)(5)(6). Even so, the discrimination of these models remains unsatisfactory with AUCs varied from 0.7 to 0.9 in previous studies (24).…”

“…The main prognostic models for assessing the overall severity of illness in critically ill adults are Acute Physiology and Chronic Health Evaluation (APACHE), Simplified Acute Physiology Score (SAPS), and Mortality Prediction Model (MPM) (2). These models, as well as Sequential Organ Failure Assess (SOFA), which was primarily designed to describe the degree of organ dysfunction in critically ill patients (3), have been found to predict mortality effectively in different clinical conditions (4)(5)(6). However, limitations for these scoring systems do exist since they are all obtained by calculating a lot of components, which makes their clinical practice complicated.…”
