The research study will investigate the longitudinal cognitive outcomes in subjects admitted as children diagnosed with sepsis who may have had acute kidney injury. Each subject will be contacted 2-15 years after their incident admission in order to solicit responses to a functional and cognitive quality of life survey. Children admitted during the same time frame that did not have kidney injury will also be surveyed.

250 subjects with a prior admission for pediatric sepsis will be contacted 2-15 years following the incident admission in order to complete a survey to assess their overall quality of life. Children will be administered the Pediatric Quality of Life (PedsQL) survey with a parental section to allow for parental response. Adult subjects will take the adult version of the PedsQL.
