New CTTI Paper Outlines Risk Factors to Aid in HABP/VABP Pediatric Trial Enrollment

A CTTI paper recently published in the Pediatric Infectious Disease Journal sheds light on risk factors that make children more likely to contract hospital-acquired and ventilator-associated bacterial pneumonia (HABP/VABP).

These risk factors are important because they could aid in earlier and more accurate diagnosis of HABP/VABP, alleviating roadblocks to enrollment in HABP/VABP clinical trials. Improved enrollment could help speed the development of new antibiotics for HABP/VABP, which can often be deadly for children.

The paper details a study conducted by the Pediatric Trials Network in collaboration CTTI, which used pediatric patients’ electronic health records to identify which patients received qualifying respiratory support or antibiotics for either a lower respiratory infection or undifferentiated sepsis. The study then followed the selected patients until they were either diagnosed with HABP/VABP or discharged from the intensive care unit.

Of 862 newborns, infants, and children younger than 18 who were evaluated, 10 percent of patients receiving respiratory support and 12 percent overall developed HABP/VABP. While risk factors varied by age group, patients showed increased odds of developing HABP/VABP if they:

  • Were older
  • Were shorter
  • Spent a longer time in the intensive care unit
  • Were at risk of aspiration
  • Had received a blood product transfusion in the prior seven days
  • Had frequent suctioning

Increased attention to patients with these high-risk features could lead to improved identification of eligible participants in HABP/VABP antibiotic trials.
