Our Pediatrics research group works in the following research lines: Child Development, Quality of Health, and Intensive Care.

In Child Development, we are especially interested in epigenetic changes associated with chronic stress situations in childhood and their repercussions on human health.

In Quality of Healthcare, we study the improvement of health processes and highlight the development of a triage tool for emergency and urgent care, the CLARIPED (CLAssification of Risk in PEDiatrics).

In Intensive Care, we highlight the study of sedation and delirium (scales validation), sepsis (early diagnosis and encephalopathy), and the validation of prognostic scores (PIM3 and PRISM IV).

Keywords: Child development, Quality of health, Pediatric Intensive Care
