Burn injuries affect nearly 500,000 Americans of all ages annually. Fortunately, approximately 90% of burn patients are treated entirely as outpatients in primary or urgent care settings. Flame injuries account for nearly half of all burns, while hot water scalding accounts for roughly one-third, with the remainder caused by contact, electrical, chemical, or other sources. Among patients requiring specialized burn center treatment, the majority are male (68%), and overall survival remains high at nearly 97%.

Clinical Concept: Approximately three-quarters of burn injuries occur in the home, while less than 10% occur in the workplace. Prevention education targeting high-risk populations—including children, elderly adults, and smokers—should be a routine component of primary care.

1. Initial Evaluation & Depth Classification

Initial assessment must begin with a multisystem survey to check and address primary airway, breathing, and circulatory compromise before focusing on the local burn injury. Once stabilized, burns are evaluated based on depth and tissue involvement:

• First Degree (Superficial): Superficially red, somewhat painful, easily blanched, and warm to the touch.
• Second Degree (Partial Thickness): Deeply red, blistered, swollen, hot to the touch, raw, moist surface, and very painful.
• Deep Second Degree (Deep Partial Thickness): Involves deeper dermal layers, appears white, and does not blanch.
• Third Degree (Full Thickness): Whitish, charred, or translucent; lacks pinprick sensation and is not painful. (Note: Third-degree burns are frequently surrounded by painful first- and second-degree burns).

To calculate Total Body Surface Area (TBSA), clinicians can use the Rule of Nines or the Palmar Surface Method, where the patient’s palm represents roughly 1% BSA across their lifespan.

2. American Burn Association Referral Criteria

According to the American Burn Association, referral to a specialized burn center (inpatient or outpatient) is recommended for:

• Partial-thickness burns >10% TBSA (>5% TBSA in children).
• Burns involving high-function or cosmetically sensitive areas: face, hands, feet, genitalia, perineum, major joints, or circumferential burns.
• Third-degree burns in any age group.
• Electrical burns (including lightning injuries) and chemical burns.
• Inhalation injury.
• Patients with preexisting medical conditions that complicate management, prolong recovery, or affect mortality.
• Burn injuries in children treated at hospitals lacking qualified pediatric personnel or equipment.
• Patients requiring special social, emotional, or rehabilitative interventions.

3. Outpatient Management & Infection Control

Smaller (<10% BSA), minor partial-thickness or superficial burns not involving critical areas can be managed outpatients. The burn surface is considered sterile for the first 48 hours. However, colonization by Gram-positive bacteria (S. aureus, coagulase-negative streptococci) occurs quickly, followed later by Gram-negative pathogens (P. aeruginosa, E. coli, K. pneumoniae) or enterococci. Routine baseline cultures are not indicated unless infection ensues.

Systemic antibiotic prophylaxis is generally not as effective as topical agents. Recommended topical options include:

4. Follow-Up & Long-Term Rehabilitation

A initial follow-up visit should be scheduled within 24 hours of injury to assess pain control and verify proper dressing changes. Subsequent visits can occur weekly (or daily during the first week if care at home is uncertain). Consider burn center or surgical referral if the wound worsens within 72 hours or causes significant scarring.

• Scar Management: Scar massage, compression garments, topical silicone, and corticosteroid injections help minimize hypertrophic scarring.
• Physical & Occupational Therapy: Recommended for burns extending over joints to prevent contractures and loss of function.
• Safeguarding & Reporting: Always evaluate patient safety; suspected non-accidental trauma or neglect in children or dependent adults must be reported to proper authorities.
