Sepsis-3 Study in Northeast Thailand

This is an observational study to evaluate the utility of the latest recommendation to define severity of infection for sepsis patients (sepsis-3), and to identify the aetiology and factors associated with outcome of community-acquired sepsis in Northeast Thailand. Potential study participants will be adult patients who are presented at the hospital with community-acquired sepsis. Clinical specimens (including blood, urine, sputum, throat swabs and pus or wound swab) will be collected from each participant on admission for culture, PCR and serological tests, and other laboratory tests. Participants' treatment will be closely monitored during the duration of their hospital stay. Blood will be again collected at 72 hours after admission. Participants will be contacted at 28 days after admission to determine clinical outcome by phone interview with standardized script.
