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.
