total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: -1
• maximum score: 8
• Patients discharged within 12 hours had a mean score of 7.1, while patients who had a longer admission had a mean score of 4.2.
• A score >= 5 identified patients who can be managed in an ambulatory care setting.
Performance:
• The authors report an area under the ROC curve of 0.91.
Modification:
• Cameron et al report a modification with each item (female sex, age < 80, access to transport, no IV, not acutely confused, MEWS 0, no recent discharge) weighted 1 point, with a total score of 7 and the cutoff >= 5.
