DYSPNEA ( Medical Research Council Scale)
category 0, No dyspnea
category 1, Slight degree of dyspnea ( troubled by shortness of breath when hurrying on the level or walking up a slight hill)
category 2, Moderate degree of dyspnea (walks slower than people of the same age on the level because of breathlessness)
category 3, Moderatly severe degree of dyspnea (has to stop because of breathlessness when walking at own pace on the level)
category 4, Severe degree of dyspnea (stops for breath after walking about 100 yards or after a few minutes on the level)
category 5, Very severe degree of dyspnea (too breathless to leave the house or breathless when dressing or undressing)

ASA Physical Status Classification System
1: A normal healthy patient
2: A patient with mild systemic disease
3: A patient with severe systemic disease
4: A patient with severe systemic disease that is a constant threat to life
5: A moribund patient who is not expected to survive without the operation
6: A declared brain-dead patient whose organs are being removed for donor purposes
These definitions appear in each annual edition of the ASA Relative Value Guide. There is no additional information that will help you further define these categories.

World Health Organization( WHO) Zubrod Performance Status Scale
0: Normal activity
1: Symptoms, but nearly fully ambulatory
2: Some bed time, but needs to be in bed less than 50% of normal daytime
3: Need to be in bed greater than 50% of normal daytime
4: Unable to get out of bed

In development data set, 94.6% of the comorbidity was related to 10 major diagnoses:
Smoking addiction (27.1%), history of cancer (11.8%), COPD (11.5%), arterial hypertension (10.5%), heart disease (10.4%), diabete mellitus (7.6%), peripheral vascular disease (6.1%) Obesity (4.9%) and alcoholism ( 4.7%).
