Consolidated guidelines on person centred hiv patient monitoring and case surveillance. Annex 2.4.6 HIVDR EWI sampling, abstraction and reporting guidance; 2017 (sólo en inglés)


This section presents a method for expanding early warning indicators (EWIs) or indicator monitoring through a random sampling of ART clinics within a country to facilitate scale up of reporting to all clinics in a country over time in a representative fashion. Use of random sampling allows countries to calculate an aggregated national prevalence estimate for each EWI.
