GHTF was comprised of five Founding Members:

• European Union,
• United States,
• Canada,
• Australia and
• Japan.

GTHF prepared a lot of helpful guidance documents -archived by IMDRF and still worth reading them - and stopped its activities in 2011.

The idea of the Medical device single audit program is to cover several jurisdictions in just one audit.

The program is run by IMDRF and currently covers the following countries quality system requirements:

• Australia
• Brazil
• Canada
• Japan
• USA

Other countries are actively participating in the discussion and may lateran join the program.
