The protocol contains sections on data collection tools and informed consent. The study was based on prospectively collected routine data , gathered for M&E purposes of the Zambian ART program. Routine clinical data was collected at enrolment using patient clinical records and entered in our study registers. At baseline the following variables were collected for patient and their clinic records to determine influence on outcome ( Age, sex, recent viral load, WHO staging, ART start date). At the time of enrolment, patient residential zones, allocated intervention model, whether they agreed to take up the offer or not and their preferences were collected in the study eligibility form. At the end of the study patient outcomes were also collected from the study documents and clinical records. Data collected via study forms were then entered in the database.
