About this Calculator

APACHE II score is a general measure of disease severity based on current physiologic measurements, age & previous health conditions. The score can help in the assessment of patients to determine the level & degree of diagnostic & therapeutic intervention.

Interpretation of APACHE II : minimum 0 and maximum 71; increasing score is associated with an increasing risk of hospital death. The advantage of the APACHE is that it can be used throughout the patient’s hospital course in monitoring the patient’s response to therapy. The accuracy of the APACHE II at admission as an early prognostic indicator of disease severity is about 75%; it is comparable with Ranson score in distinguishing mild from severe pancreatitis.
