What are the discharge criteria for a patient post appendectomy?

Discharge Criteria for Post-Appendectomy Patients

Patients can be safely discharged after appendectomy when they have stable vital signs (temperature ≤38°C for 24 hours), adequate pain control with oral analgesics, are ambulatory, and show no signs of complications—without requiring bowel function, oral intake, or voiding. 1

Core Mandatory Discharge Criteria

The following criteria must ALL be met before discharge:

• Stable vital signs with temperature ≤38°C for 24 hours 1
• Adequate pain control achievable with oral analgesics alone 1, 2
• Patient is ambulatory and able to move independently 1
• Return of protective airway reflexes (if general anesthesia was used) 1
• Absence of complications including peritoneal signs, excessive wound drainage, or hemodynamic instability 1

What is NOT Required for Discharge

A critical pitfall is delaying discharge waiting for traditional milestones that are unnecessary:

• Passing flatus or stool is NOT mandatory for discharge 1
• Tolerating oral fluids is NOT required and may actually provoke nausea/vomiting and delay discharge 1
• Voiding is NOT universally required 1

These outdated requirements should be abandoned, as they unnecessarily prolong hospitalization without improving safety. 1

Timeline for Discharge

Uncomplicated (Non-Perforated) Appendicitis

• Discharge within 48 hours is both feasible and safe 1, 3
• Same-day discharge (within 24 hours) is safe when discharge criteria are met, particularly in pediatric patients with readmission rates of only 1.89% 1, 4
• The median time to meet discharge criteria is typically 2 days postoperatively 2

Complicated (Perforated) Appendicitis

• Discharge criteria can be met by median of 2 days even in complex appendicitis 2
• Patients can be safely discharged prior to completing a full 5-day intravenous antibiotic course if discharge criteria are met and leukocyte counts are normal 5

Antibiotic Management at Discharge

For Uncomplicated Appendicitis

• No postoperative antibiotics are required after appendectomy for non-perforated appendicitis 1, 6
• A single preoperative dose only (0-60 minutes before incision) is sufficient 1, 6

For Complicated (Perforated) Appendicitis

• Early switch to oral antibiotics after 48 hours if clinically improving 1, 6
• Total antibiotic duration <7 days, with 3-5 days typically sufficient when adequate source control achieved 1, 6
• Discharge on oral antibiotics is safe and cost-effective when patient is otherwise stable 1, 6
• Patients meeting discharge criteria with normal leukocyte count can be discharged without oral antibiotics even if less than 5 days of IV therapy completed 5

Mandatory Discharge Requirements

Before any patient leaves the hospital, you must provide:

• Written AND verbal discharge instructions covering diet, activity, medications, and warning signs of complications 1
• Instructions to both patient and responsible caregiver 1
• Adequate oral analgesics with clear usage instructions 1
• 24-hour contact information for postoperative concerns 1

Special Populations

Pediatric Patients

• Same-day discharge is safe when criteria are met 1, 4
• Shorter time between surgical admission and operation (5.8 vs 11.4 hours) facilitates same-day discharge without increasing complications 4

Elderly Patients

• Mild postoperative confusion alone should not prevent discharge if social support is adequate 1
• Avoiding hospitalization is preferred for minor procedures when safe 1

Common Pitfalls to Avoid

• Do NOT delay discharge waiting for bowel function 1
• Do NOT mandate oral intake before discharge 1
• Do NOT confuse perforated with non-perforated cases regarding antibiotic needs 1, 6
• Do NOT discharge without adequate pain control 1
• Do NOT discharge elderly patients with mild confusion alone without ensuring adequate social support 1
• Do NOT extend antibiotics beyond 3-5 days even for complicated appendicitis when adequate source control achieved—longer courses do not reduce abscess rates and increase antibiotic-related complications 6

Nurse-Led Discharge Protocol

Standardized discharge protocols managed by nursing staff are appropriate and safe, with the surgeon or anesthetist remaining contactable for complications. 1 This approach streamlines the discharge process while maintaining safety.
