Age >80 years	Age in years	1
Male sex	+10
History of cancer	+30	1
History of heart failure	+10	1 or ^{^‡}
History of chronic lung disease	+10	or 1
Pulse ≥110 beats per minute	+20	1
Systolic blood pressure <100 mmHg	+30	1
Respiratory rate ≥30 breaths per minute	+20

^*A total point score for a given patient is obtained by summing the patient’s age in years and the points for each predictor when present. The score corresponds with the following risk classes: 65 or less, class I; 66–85, class II; 86–105, class III; 106–125, class IV; and more than 125, class V. Patients in risk classes I and II are defined as being at low risk.

^†A total point score for a given patient is obtained by summing the points. The score corresponds with the following risk classes: 0, low risk; 1 or more, high risk. Empty cells indicate that the variable was not included.

^‡The variables were combined into a single category of chronic cardiopulmonary disease.
