  Figure 1.. Performance of All Scores Across Continuous Scoring for All Hospitals and First Discharges The modified LACE (mLACE) score was calculated at discharge using 4 items: length of stay, acuity of admission, comorbidities, and emergency department visits 6 months before hospital admission. The Maxim/RightCare score was calculated 48 hours after admission using a proprietary formula. The HOSPITAL score was calculated at discharge using 7 variables (hemoglobin level, discharge from an oncology service, sodium level, procedure during the index admission, index type of admission, number of admissions during the past 12 months, and length of stay) to categorize patients as low, medium, or high risk. B score indicates Baltimore score.
