Burn center referral criteria

Overview

Burn center referral criteria define which injuries warrant transfer to a verified burn center for specialized care. The American Burn Association maintains consensus-based criteria that include burns exceeding 10% TBSA, full-thickness burns of any size, burns to critical areas (face, hands, feet, genitalia, major joints), electrical and chemical injuries, and inhalation injury ^[1]. Adherence to these criteria varies widely across healthcare systems, with under-triage rates ranging from 18% to over 60% depending on the criterion and setting ^[2]. Under-triage means patients who need burn center care do not get it. Over-triage, driven largely by TBSA overestimation, overwhelms burn center resources with patients who could be managed locally.

Classification

Current ABA referral criteria

The eDelphi consensus by Bettencourt et al. updated the ABA referral criteria, confirming the following indications for burn center referral ^[1]:

• Burns greater than 10% TBSA
• Full-thickness burns of any size
• Burns to critical areas (face, hands, feet, genitalia, perineum, major joints)
• Electrical burns (including lightning)
• Chemical burns
• Inhalation injury
• Burns in patients with preexisting medical conditions that could complicate management
• Burns with concomitant trauma where the burn poses the greatest risk

The consensus process also identified the need to address frequent overestimation of burn size by referring providers as a driver of inappropriate transfers ^[1].

Assessment

Adherence measurement

Bazzi et al. performed a systematic review of adherence to burn referral criteria across multiple healthcare systems, finding that adherence varied widely with under-triage rates from 18% to over 60% depending on the criterion and healthcare setting ^[2].

Pediatric referral patterns

A large pediatric cohort study found that a substantial proportion of children meeting ABA referral criteria were not transferred to burn centers, with younger age and lower socioeconomic status associated with higher rates of missed referral ^[3].

Management

Pre-transfer airway management

Donnelly et al. reported that pre-burn center intubation was associated with higher rates of pneumonia and longer ventilator days, suggesting that prophylactic intubation before transfer may cause iatrogenic harm ^[4]. This finding supports selective rather than prophylactic intubation when the airway is currently patent.

System-level interventions

Educating referring providers on accurate TBSA estimation and appropriate transfer indications directly reduces both under-triage and over-triage ^[1][2]. Deploying standardized digital estimation tools to referring facilities is an actionable systems intervention.

Controversies and Evidence Gaps

The eDelphi consensus reflects expert opinion rather than controlled outcome data. Adherence studies are heterogeneous in methodology, making direct comparison of under-triage rates across systems difficult ^[2]. The intubation systematic review includes observational studies with significant confounding by indication ^[4]. Long-term outcome comparisons between patients treated at burn centers versus non-burn centers remain limited. Whether prophylactic intubation for transfer causes iatrogenic harm is an active area of debate.
