Discharge Criteria

Introduction & Principles - Gatekeeper's Guide

• Primary Goal: Safe patient transition from acute care (PACU/hospital) to home or a lower level of care. Balances timely discharge with patient safety.
• Gatekeeper Function: Anesthesiologist/care team ensures all discharge criteria are met before release.
• Key Considerations (The "SAFE" approach 📌):
  • Stability: Vital signs stable, pain controlled (<4/10), Postoperative Nausea and Vomiting (PONV) minimal.
  • Alertness: Awake, oriented, protective reflexes present.
  • Function: Able to ambulate (as appropriate for age/surgery), tolerate oral fluids.
  • Education: Understands post-operative instructions, has a responsible adult escort.
• Focus: Minimize complications, prevent readmission, ensure adequate home support and follow-up.

⭐ Standardized discharge scoring systems (e.g., Aldrete Score, Post Anesthetic Discharge Scoring System - PADSS) objectify readiness, but overall clinical judgment remains paramount.

Scoring Systems - Numbers Game Ready

• Standardized tools for objective discharge assessment. Clinical judgment is paramount.
• Modified Aldrete Score (MAS): Widely used post-PACU.
  • Assesses 5 criteria: Activity, Respiration, Circulation, Consciousness, O2 Saturation.
  • Scoring: Each 0, 1, or 2. Max score: 10.
  • Discharge: Score ≥ 9.
• Post Anesthetic Discharge Scoring System (PADSS): For ambulatory surgery.
  • Assesses 5 criteria: Vital signs, Activity/ambulation, Nausea/Vomiting (N/V), Pain, Surgical bleeding.
  • Scoring: Each 0, 1, or 2. Max score: 10.
  • Discharge: Score ≥ 9.
• Fast-Track Criteria (e.g., White-Song): Allows bypassing Phase I PACU.
  • Key elements: Minimal pain & N/V, stable vitals, able to ambulate.

⭐ For MAS, a patient must maintain SpO2 > 90% on room air to score 2 for O2 saturation; needing supplemental O2 for SpO2 > 90% scores 1.

Specific Criteria - Homeward Hurdles

Patients must clear these physiological hurdles before discharge, complementing scoring systems (e.g., PADSS).

• Core Stability:
  • Vitals: Stable for >1 hr (BP ±20% baseline, HR <100 bpm, RR 12-20/min, Temp 36-37.5°C ($96.8-99.5°F$), SpO2 ≥94% RA).
  • Cognition: Alert, oriented to baseline.
• Functional Recovery:
  • Pain: Controlled (VAS ≤3-4/10) with oral analgesia.
  • PONV: Minimal, tolerating oral fluids.
  • Mobility: Ambulating safely as appropriate. No dizziness.
  • Urinary: Voided spontaneously (if risk of retention, e.g., spinal, pelvic surgery). Urine output >0.5 mL/kg/hr.
• Surgical Site:
  • No active bleeding/excessive discharge.
• Discharge Readiness:
  • Understands instructions.
  • Responsible adult escort present for 24h.

📌 Mnemonic: "SAFE HOMER" - Stable vitals, Analgesia/No PONV, Fluids, Escort, Haemostasis, Orientation, Mobility, Education, Renal (voiding).

⭐ > Post-spinal anesthesia, ability to void is a critical hurdle. Patients must void ~200-300 mL before discharge to rule out urinary retention.

Discharge Process & Education - Final Lap Smoothly

• Smooth Transition Home:
  • Clear verbal & written instructions: medications (dose, timing, side effects), activity restrictions, wound care, diet.
  • Red flag symptoms explained: e.g., fever >38°C, uncontrolled pain, new/excessive swelling or discharge, persistent nausea/vomiting.
  • Follow-up appointment details provided.
• Essential Paperwork:
  • Comprehensive, accurate discharge summary.
  • Legible prescriptions with clear instructions.
• Final Checks:
  • Patient verbalizes understanding of key instructions.
  • Responsible adult escort confirmed for safe transport.

⭐ Inadequate patient education on warning signs and when to seek help is a leading cause of preventable readmissions and post-operative morbidity.

High‑Yield Points - ⚡ Biggest Takeaways

• Stable vital signs (BP, HR, RR, Temp) for at least 1 hour are crucial.
• Patient must be fully awake, alert, and oriented (A&O x 3).
• Pain adequately controlled with oral analgesics, score < 4/10.
• Minimal nausea/vomiting; tolerating oral fluids and able to void.
• Ambulatory as appropriate; no active bleeding or discharge concerns.
• Aldrete score ≥ 9 or PADSS ≥ 9 often required for discharge.
• Responsible adult escort and comprehensive discharge instructions provided.
