Modified (1995) Aldrete Score: 10/10 - Discharge criteria met.

  • A score of 9 or 10 meets the standard threshold for safe transfer from the PACU to a ward or discharge from an outpatient setting.
  • The Aldrete Score does not assess pain, nausea, vomiting, temperature, or surgical-site issues. Evaluate these separately before making a discharge decision.

Next stepConfirm pain is controlled, nausea is minimal, and the patient can safely ambulate (if applicable) before completing PACU discharge documentation.
