The Interagency Guidelines for Drug Donations were issued in May 1996 by the WHO Action Programme on Essential Drugs (WHO/DAP) on behalf of eight international agencies active in humanitarian emergency relief. That same month WHO was requested by the World Health Assembly to review the experiences with the Guidelines after one year. In autumn 1997 WHO therefore initiated a global review of first-year experiences with the Guidelines. The results of that review are presented in this report.
