Advice
  • No definitive management recommendations have been made based on ATLAS score results.
  • For lower scores: Consider less intensive treatment and possible outpatient management, if the patient is clinically stable.
  • For higher scores: Escalate care, potentially involving infectious disease consultation, hospitalization, or ICU care if warranted.
  • Use alongside clinical judgment; the score complements, but does not replace, bedside evaluation.
