Impact of the Korea Early Childhood Home-visiting Intervention (KECHI) on child health and development and maternal health: a randomised controlled trial protocol

Introduction Randomised controlled trials (RCTs) of early childhood home-visiting interventions led by nurses have been conducted mainly in Western countries, whereas such trials have been limited in non-Western cultures, including Asia. In South Korea, a national nurse home visit programme (Korea Early Childhood Home-visiting Intervention (KECHI)) was developed in 2020 and launched throughout the country.
