Yasal Uyarı: Bu platformdaki klinik skorlamalar ve algoritmalar yalnızca sağlık profesyonellerini bilgilendirme amaçlıdır. Herhangi bir kesin tıbbi teşhis, tedavi veya klinik karar yerine geçemez. Nihai karar ve sorumluluk hastayı yatak başında değerlendiren hekime aittir.

Clinical Overview

The Acute Physiology and Chronic Health Evaluation (APACHE) II is a widely used severity-of-disease classification system. Calculated within the first 24 hours of ICU admission, it integrates 12 physiological variables, age, and severe chronic health conditions to accurately estimate the probability of in-hospital mortality.

Clinical Pearl

Always use the worst physiological values recorded during the initial 24 hours of ICU admission, not necessarily the admission values themselves. This captures the peak physiological derangement and ensures scoring accuracy.

Pitfalls & Warnings

  • Designed and validated only for the first 24 hours of ICU admission; calculating it daily thereafter is not recommended or validated.
  • Patients admitted with acute burn injuries, coronary artery bypass grafts (CABG), or those younger than 16 years were excluded from the original validation.
