Adaptation of the survey forms for Ghana, training of data collectors, field-testing and district and facility sampling were carried out at the training workshop held 11-15 October 2002. Annexes 3 and 4 contain a summary of adaptations, the districts and facilities sampled and the adapted survey forms.

In order to ensure a fair representation, the ten regions in Ghana were divided into four categories, according to the following criteria and four of them subsequently selected.

• Socio-economic profile
• Proximity to the Central Medical Stores
• Presence of a particular strong support to the regional drugs programme

The four regional categories comprised the following:

• Greater Accra,
• Eastern region, Central region and Volta region
• Western region, Ashanti and Brong Ahafo
• Northern, Upper-East and Upper West region

Within each region, the following facilities and households were selected based on a combination of purposive and systematic random sampling:

• public health facilities including the regional, a district hospital and 3 health centres (in this survey public health facility refers to either government or private-not-for-profit/NGO health facility)

• 5 private pharmacies/drug outlets/chemical sellers close to the selected public health facility

• 1 central/district drugs warehouse/storage facility

• 15 households within 5km of each selected public health facility.
