The Guideline Group aimed to gather evidence on the policies and legislation that exist in 34 countries, with 4 of 6 WHO regions responding prior to the drafting of the Synthesis report (Yassi et al., 2009). The purpose was to identify gaps in policy and barriers to implementing related policies related to improving healthcare worker access to HIV and TB services. Overall HIV and TB prevalence determined the number of countries to be surveyed for each region. Within each country, the WHO HIV officer liaised with their respective Ministry of Health to facilitate collection of data.

The Five Country Study by Corbett (2007a) provides high quality evidence relevant to developing guidelines. The methodology included interviews with 938 health workers from 50 facilities across five African countries (Ethiopia, Kenya, Malawi, Mozambique, and Zimbabwe), 30 of which were selected through random cluster sampling, with the others selected through purposive selection seeking facilities with best practices.
