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
| Points | 4 | 3 | 2 | 1 | 0 | 1 | 2 | 3 | 4 |
| 1. temperature
(C) |
≥41 | 39-40.9 | 38.5-38.9 | 36-38.4 | 34-35.9 | 32-33.9 | 30-31.9 | ≤ 29.9 | |
| 2. mean BP
(mm Hg) |
≥160 | 130-159 | 110-129 | 70-109 | 50-69 | ≤49 | |||
| 3. HR
(beats per minute) |
≥180 | 140-179 | 110-139 | 70-109 | 55-69 | 40-54 | ≤39 | ||

Glasgow Coma Scale
For information on collecting and coding the values, see the Glasgow Coma Scale article.
Age Points
The age of the patient is automatically generated from the date of birth and the date of admission when collecting data.
- agepts
| Age | ≤44 | 45-54 | 55-64 | 65-74 | ≥75 |
| Points | 0 | 2 | 3 | 5 | 6 |
Chronic Health Diagnosis for APACHE II
- Chempt = chronic health points.
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 Diagnosis for APACHE II 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 |
See Chronic Health Diagnosis for APACHE II
Total Apache Score
TotApache = APS + GCS + chempts + agepts
APSpts-Acute Physiological Points
APS= scores Apache items 1-11 + GCS
