== Background ==
The APACHE II model to predict death rate for groups of acutely ill patients is composed of the [[APACHE Score]], sets of principal diagnostic categories leading to ICU admission and type of patient as nonoperative or post-operative.  Each diagnostic category has corresponding weight in the model. 

The list of the diagnostic categories is shown in [[APACHE Acute Dxs in ICD10 codes]] and its  associated weights are shown in the [[S ICD10 APACHE Dx patterns table]].

There are 30 non-operative diagnosis categories and 24 post-operative diagnosis categories included in the APACHE Death predictive model.   These diagnosis categories are further grouped into '''eight''' broad categories by Dr. Kendiss Olafson for QI reporting purposes as follows: 
# Respiratory Disorders
# Cardiac Disorders
# Post Cardiac Arrest
# Neurologic Disorders
# Trauma and Poisoning
# Post-Operative Care
# Metabolic,Renal & GI Disorders, Hypovolemic Shock
# Sepsis and Septic Shock
The eight Broader Diagnostic Categories or '''DxGrp_label''' are also included in the [[S ICD10 APACHE Dx patterns table]].
===QI domain===
*Understanding of patient population

==Sampling Plan / Procedure==

===Inclusion Criteria===
100% Admissions - see [[Definition of a Critical Care Laptop Admission]]  
===Exclusion Criteria===

===Frequency===
Time Reference for month, quarter or year can be based on ICU admission dates or ICU discharge dates. The Critical Report uses the ICU [[Dispo DtTm]]

==Definition and Derivation==
*Post Operative patient - when the patient's [[Previous Location]] prior to ICU is Operating or Recovery Room.
*The patient based on the [[Admit Diagnoses]] and/or admit procedures maybe assigned to one or more diagnostic categories. 
**The diagnostic category with the highest weight is the final diagnostic category assigned to the patient. 

===Numerator===
Total number of patients in each of the 8 Broad Diagnostic Categories
===Denominator===
Total number of discharges
