The Possible Serious Bacterial Infection (PSBI) dataset contains information related to the identification, management, and outcomes of young infants and children who exhibit signs of serious bacterial infections. These infections may include conditions such as sepsis, pneumonia, meningitis, and other life-threatening bacterial illnesses, particularly among newborns and infants under two months of age. The dataset typically records patient demographics, clinical symptoms, diagnostic assessments, treatment interventions, referral status, recovery outcomes, and healthcare facility information. It is valuable for monitoring neonatal and child health programs, evaluating the effectiveness of infection management protocols, assessing healthcare service delivery, and supporting research aimed at reducing infant morbidity and mortality associated with bacterial infections.
