APACHE Scoring table
The Scoring table for APACHE II describes how various fields we collect affect the ultimate APACHE II score.
The calculation of the store happens automatically and data collectors do not need to fit patient scores into this ranking or perform calculations.
Physiological Variables

definitions
A lot of these values follow very specific definitions and collection instructions. See individual linked articles for details. Especially, see
number of decimal points in definitions
Some values arrive with a higher decimal precision than the definitions. Since the definitions have holes, that would lead to values in the holes being undefined for points. This is solved by rounding the value to one decimal point and applying the score to that.
Glasgow Coma Scale (GCS)
For information on collecting and coding the values, see the Glasgow Coma Scale article.
- GCS = EYE point + MOTOR point + VERBAL point
- Neurological Points = 15 - GCS
Acute Physiologic Score (APS)
APS = #Physiological_Variables points + Neurological points from GCS
Inclusion of pH in absence of other ABG components

Age Points
The age of the patient is automatically generated from the date of birth and the date of admission when collecting data.
| Age | ≤44 | 45-54 | 55-64 | 65-74 | ≥75 |
| Points (agepts) | 0 | 2 | 3 | 5 | 6 |
Chronic Health Score
The chronic health score is calculated from Chronic Health APACHE and Admit Type for APACHE II as follows:
Correct scoring for Apache II Chronic Health
- If admit type is: "Medical (non operative)" or "Emergency Surgery" PLUS one or more Chronic Health APACHE is present:
- Score = 5
- If "elective surgery" PLUS one or more Chronic Health APACHEis present:
- Score = 2
- if Chronic Health APACHE is "none" then
- Score = 0
Total Apache Score
TotApache = APS + Chronic Health points+ agepts
