Aim 2: Examine effects of algorithm-guided alcohol treatment on retention in HIV care and HIV-related outcomes. Hypothesis 2A. Patients treated using algorithm-guided treatment will increase adherence to clinic visits and HIV medications compared to pre-algorithm levels. Hypothesis 2B. Patients who receive algorithm-guided treatment will have improved HIV biomarkers (e.g., CD4 and VL). Hypothesis 3B. There will be a positive relationship between VL and alcohol consumption measured by self-report and PEth level.
