Overview

Under-triage is a major threat when admitting patients at the Intermediate Care Unit (IMCU). This study aims to identify risk factors and predict early deterioration of IMCU admissions, to reduce the risk of under-triage. This retrospective cohort study included all admissions to the mixed-surgical stand-alone IMCU of a tertiary referral hospital (2001–2015). Variables included were age, sex, admission indication, admitting specialty, re-admission, and nursing interventions. Early clinical deterioration was defined as ICU transfer or death ≤24 h of admission. Multinomial and logistic regression analyses were performed to identify risk factors and obtain predictions, for several frequently encountered subgroups. A total of 9103 admissions were included, of which 350 (3.8%) early deteriorated. Patients admitted for hemodynamic and respiratory instability had a high risk of early deterioration (OR 16.3 (CI 4.5-59.1)), probability 47.1%. Patients admitted with respiratory insufficiency and active diuresis or complicated sepsis had a high probability of early deterioration (≥29% and ≥26% respectively). The model had an optimism-corrected c-statistic of 0.79 (IQR 0.78-0.80). Patients with combined hemodynamic and respiratory instability should not be admitted to the IMCU. Patients with respiratory insufficiency and active diuresis, or complicated sepsis require close monitoring. •The presented nomogram can be used to assess the probability of early clinical deterioration•Patients with hemodynamic and respiratory instability should be admitted at the ICU•IMCU Patients with respiratory insufficiency and active diuresis, or complicated sepsis require close monitoring
