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

Points	4	3	2	1	0	1	2	3	4
temperature (C)	≥41	39-40.9		38.5-38.9	36-38.4	34-35.9	32-33.9	30-31.9	≤ 29.9
mean BP (mm Hg)	≥160	130-159	110-129		70-109		50-69	≤49
HR (beats per minute)	≥180	140-179	110-139		70-109		55-69	40-54	≤39
RR (breaths per minute)	≥50	35-49		25-34	12-24	10-11	6-9		≤5
AaDO2 (if FiO2 >= 50%)	≥500	350-499	201-349		200
PO2 (mm Hg) (if FiO2 < 50%)					70	61-69		55-60	≤54
Arterial pH	≥7.7	7.6-7.69		7.5-7.59	7.33-7.49		7.25-7.32	7.15-7.24	≤ 7.14
Serum CO2 (If no ABG)	≥52	41-51.9		32-40.9	22-31.9		18-21.9	15-17.9	≤14
Na (mmol/L)	≥180	160-179	155-159	150-154	130-149		120-129	111-119	≤110
K (mmol/L)	≥7	6-6.9		5.5-5.9	3.5-5.4	3-3.4	2.5-2.9		≤2.4
Creatinine (mmol/L) (*Double point if yes for ARF)	≥309	178-308	133-177		53-132		52
HCT (unit?)	≥60		50-59.9	46-49.9	30-45.9		20-29.9		≤19
WBC(?unit)	≥40		20-39.9	15-19.9	3-14.9		1-2.9		<1

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

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
