Normalize function for at-risk patients

  • Monitor for and prevent dehydration
  • Offer nutrition if not NPO and/or absence of dysphagia
  • Assess for and treat constipation/urinary retention
  • Vision/Hearing aids present at bedside
  • Early mobility
  • Sleep hygiene
    • Avoid placing at-risk patients in hallways overnight
    • Observation-unit patients:
      • Minimize nighttime disruptions (nighttime vital signs, blood draws, medications)
      • Consider nonpharmacologic measures to improve sleep
