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.
A Glasgow Coma Scale score of 15 would be considered "Total Neuro Points".
The Glasgow Coma Scale is scored in APACHE II as follows:
| Points | 6 | 5 | 4 | 3 | 2 | 1 |
| Eyes | Spontaneous | To Speech | To Pain | None | ||
| Motor | Obeys Command | Localizes Pain | Withdraws to Pain | Abnormal Flexion | Abnormal Extension | None |
| Verbal | Oriented | Confused | Inappropriate words | Incomprehensive sounds | None |
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 | 0 | 2 | 3 | 5 | 6 |
before de-stubbing
- confirm if age calculated from admission date
- YES TOstryzniuk 16:48, 16 June 2008 (CDT)
Chronic Health
We pull some of the values for the chronic health score from the coded diagnoses and some from ...
- APACHE II has some "specific" underlying disease conditions that it uses. Not just any code from the main DX code list.
- this information needs to be added here.
The Chronic health field is scored as follows:
| Points | 0 | 2 | 5 |
| Chronic Health Status | No history of chronic disease | Elective Post op with history of chronic disease | Non OP (medical) or emergency post op with history of chronic disease |
