Every year, rich Indonesians spend far more than $1 billion for their medical expenses overseas, according to the research and consulting firm Frost and Sullivan. The findings means a big potential loss for the domestic healthcare business, said Frost and Sullivan representatives. The figures confirm earlier statements by Fahmi Idris, chairman of the Indonesian Medical Association, that suggested at least 1 million Indonesians every year go abroad seeking health services and spend well over $1 billion.
