This tool is designed to help determine if a patient with burn injuries should be transferred to a burn unit. It evaluates several key factors and provides an outcome based on the criteria typically used in clinical practice for making such decisions.

The evaluation considers these aspects of a burn injury:

- **Burn Thickness**:
  - Are there partial-thickness burns affecting more than 10% of the Total Body Surface Area (TBSA)?
  - Are there full-thickness burns present in the patient?

- **High-risk Locations of Burns**:
  - Does the patient have burns on the face?
  - Are the burns on the hands and/or feet?
  - Are the burns located on the genitalia and/or perineum?
  - Are any major joints affected by the burns?

- **Special Types of Burns**:
  - Has the patient suffered electrical burns, including injuries from lightning?
  - Are there chemical burns?
  - Is there an inhalation injury involved with the case?

- **Comorbidities and Additional Factors**:
  - Are there pre-existing medical disorders that could complicate the management, recovery, or increase mortality risk?
  - Is there any concomitant trauma (such as fractures) where the burns pose the primary risk to health?

- **Special Considerations**:
  - Is the burn injury in a child being treated in a hospital that lacks qualified personnel or equipment for pediatric burn care?
  - Does the patient require special social, emotional, or rehabilitative intervention due to the burn injury?

The tool assesses the presence of these characteristics in the patient's condition. If any of these conditions are met, it indicates that the patient meets the criteria for a transfer to a burn unit, signaling the need for specialized care. It does not weigh one condition against another; the existence of any single criterion suffices to recommend the transfer, emphasizing the critical nature of these factors in managing burn injuries effectively. The result succinctly communicates whether the criteria for transfer are met, enabling a quick decision-making process.

The calculator in question is the ABA Criteria for Transfer to a Burn Unit, where ABA stands for American Burn Association. This scoring system is used to determine the need for a patient with burn injuries to be transferred to a specialized burn unit. It applies to patients of all ages who have sustained burn injuries.

The clinical utility of this calculator is to guide clinicians in making decisions about the appropriate level of care for patients with burn injuries. It takes into consideration factors such as the extent and depth of the burn, the patient's age, the presence of inhalation injury, and associated injuries or comorbidities. 

There are no specific exclusion criteria for the use of the ABA Criteria for Transfer to a Burn Unit. However, it should be noted that the decision to transfer a patient should not be based solely on these criteria, but should also take into account the overall clinical condition of the patient and the resources available at the current facility.
