The South East Asia Infectious Disease Clinical Research Network (SEAICRN) is a partnership of hospitals and research institutions in Indonesia, Thailand and Vietnam that conducts clinical research on critical infectious diseases in the region. Currently, FHI 360 is supporting the SEAICRN to conduct a study to understand the causes of community-acquired sepsis and severe sepsis. FHI 360 helps SEAICRN enhance the capacity of clinical research sites to perform studies in accordance with international standards and facilitates the planning and conduct of studies. We conduct site assessments, trainings and activities to build research capacity. FHI 360 also helps the sites develop and implement quality research systems, particularly with reference to Good Clinical Practices and regulations for protecting human participants in clinical trials. Our support for clinical laboratory systems involves working with site investigators, local governments and research institutions in Thailand and Vietnam to advance the scientific knowledge and management of emerging infectious diseases through integrated, collaborative international clinical research.
