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.

Glasgow Coma Scale
For information on collecting and coding the values, see the Glasgow Coma Scale article.
- GCS
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.
The chronic health score is generated as follows:
| Points | Chronic Health Status |
| 0 | No history of chronic disease |
| 2 | Elective Post op with history of chronic disease |
| 5 | Non OP (medical) or emergency post op with history of chronic disease |
Template:Discussion
What about those with chronic health and no surgery at all? Ttenbergen 16:37, 28 October 2010 (CDT)
- no surgery + CH= 5 points (non OP medical). --TOstryzniuk 13:42, 29 October 2010 (CDT)
- so someone with a history of chronic disease would be considered at lower risk if they have surgery than if they don't? Ttenbergen 10:07, 1 November 2010 (CDT)
