Assessing eligibility for differentiated service delivery, HIV services utilization and virologic outcomes of adult HIV-infected patients in Sierra Leone: a pre-implementation analysis.

Approximately one in three HIV-infected patients on ART were eligible for DSD. We identified gaps in HIV care (i.e. low partner testing, treatment 'buddy', program participation and a substantially high rate of virologic failure) that need to be addressed in preparation for full implementation of DSD in Sierra Leone.
