Hanoi group

The Oxford Clinical Research Unit, Hanoi (OUCRU Hanoi) was established in 2006 and is hosted by the National Hospital of Tropical Diseases (NHTD). NHTD is a tertiary level teaching hospital, receiving infection related referrals from northern Vietnam and has close ties to the Ministry of Health (MoH).

Through its partnership with NHTD, OUCRU Hanoi also works with other hospitals and institutes in the region, including the National Institute for Hygiene and Epidemiology, the National Paediatric Hospital, the National Lung Hospital, National Center for Veterinary Diagnosis, and regional hospitals and health stations. The research programme at OUCRU Hanoi focuses on clinical and epidemiological aspects of respiratory infections (both bacterial and viral), antimicrobial resistance, zoonosis (including Streptococcus suis) and dengue. Furthermore, OUCRU Hanoi is studying zoonotic infections in collaboration with Hanoi Medical University as part of the VIZIONS project. Through NHTD OUCRU Hanoi has also been involved in consultations with MoH on antibiotic treatment guidelines, management of avian influenza and Streptococcus suis, and other public health issues.

The importance of OUCRU Hanoi in Viet Nam.

OUCRU Hanoi is close to all the key national institutes in Vietnam (see partners/collaborators) and the Ministry of Health. These relations ensure that OUCRU research findings also find their way into policies. Our research in the area of antibiotic resistance supported the development of a National Action Plan on Antibiotic Resistance that was signed by the Minister of Health mid 2013.

Our research locations

OUCRU Hanoi is based at the National Hospital of Tropical Diseases and. We also have research offices and laboratory capacity at National Institute of Hygiene and Epidemiology (NIHE), National Hospital of Paediatrics and Hanoi Medical University (HMU). With NIHE we now conduct influenza household transmission studies for over 7 years in Ha Nam. With HMU we conduct community based studies in Ba Vi and Dong Da.

Key milestones

We recently completed a national program (VINARES) to assess hospital acquired infections, antibiotic use and antibiotic resistance in 16 hospitals across Vietnam. We had a closing meeting in October 2013 with 120 international participants in Hanoi.

We are running one of the longest influenza household cohorts worldwide in Ha Nam, Vietnam. This cohort has been ongoing for over 7 years leading to new knowledge in the area of influenza transmission and immunology.
