Role of evidence in maternal health policy processes in Vietnam, India and China: findings from the HEPVIC project

This paper explores the role of evidence in maternal health policy processes in Vietnam, India and China. Both formal and informal types of evidence were used; and differences were found between the stages of policy processes. Evidence used mostly covered easily quantifiable issues and clearly identifiable technical solutions. Different policy actors were involved; actors' evidence preferences were affected by their power, agendas, values and perceived characteristics of robust evidence. To enhance evidence role there is a need to: develop culture of evidence-informed policies; value different evidence types; ensure evidence use throughout policy processes; recognise and manage actors' agendas; and develop context-specific strategies.
