The variables Discharge ADLs, Expected ADLs, and Prior ADLs/IADLs use increments of 1,000 points in calculating the odds ratios and confidence intervals.
NOTES: CI is confidence intervals. COPD is chronic obstructive pulmonary disease. CHF is congestive heart failure. ADLs is activities of daily living. IADLs is instrumental activities of daily living. HMO is health maintenance organization. APS is acute physiology score.
