We are conducting an implementation science study using a two-arm cluster site-randomized design to determine the effectiveness of a combination intervention strategy ( CIS ) using feasible , evidence-based , and practical interventions-including ( 1 ) point-of-care ( POC ) CD4 count testing , ( 2 ) accelerated antiretroviral therapy initiation for eligible individuals , and ( 3 ) SMS reminders for linkage to and retention in care-as compared to the standard of care ( SOC ) in Mozambique in improving linkage and retention among adults following HIV diagnosis .
