Which patients are at risk for an Acinetobacter baumannii infection?

Acinetobacter baumannii is a type of bacteria that is known to cause infections, particularly in hospitalized patients with certain risk factors. The group of patients at the highest risk includes those who have undergone invasive procedures, such as a tracheostomy. A tracheostomy creates an opening in the neck that allows for direct access to the airway, which can facilitate the entry of pathogens, including Acinetobacter, into the respiratory system.

Patients with tracheostomies often require prolonged mechanical ventilation and may already have compromised immune defenses or the presence of other medical devices, increasing their susceptibility to infections. The wound created by the procedure can also become a potential entry point for bacteria.

While military personnel and athletes can have unique exposure risks, particularly regarding certain infections, they are not inherently at the same level of risk for Acinetobacter baumannii infections as those who have undergone tracheostomy or are on mechanical ventilation. Risk factors tied to healthcare settings, underlying health conditions, and invasive procedures are more directly associated with this particular pathogen. Therefore, the choice highlighting a patient with a tracheostomy procedure accurately reflects the increased risk associated with that medical intervention.
