The Pollock-Flickinger score, also known as the Acute Physiology and Chronic Health Evaluation (APACHE) score, is a scoring system used to assess the severity of illness and the likelihood of survival of patients in intensive care units (ICUs).

The score is calculated based on a patient's vital signs, laboratory values, and other clinical factors. The higher the score, the more severe the illness, and the lower the likelihood of survival. The Pollock-Flickinger score is widely used in ICUs to guide treatment decisions and assess the effectiveness of interventions.

It is important to note that the Pollock-Flickinger score is just one tool among many used in critical care medicine and should not be used in isolation to make clinical decisions. The score should be used in conjunction with a thorough clinical assessment and the judgment of the treating physician
