The Acute Physiology and Chronic Health Evaluation (APACHE)

The Acute Physiology and Chronic Health Evaluation (APACHE) is a tool used by healthcare professionals to assess the severity of illness in critically ill patients. It helps estimate the risk of death by analyzing various physiological measurements (like heart rate, blood pressure, and blood tests) taken within the first 24 hours of ICU admission. By calculating a score, clinicians can better understand a patient's condition, guide treatment decisions, and predict outcomes. Essentially, APACHE provides a standardized way to evaluate how severely a patient is affected and assists in monitoring their progress and adjusting care accordingly.
