Engagement in the Cascade of Care in BC Nosyk et al, TasP Workshop, 2013 Engagement in the Cascade of Care in BC Nosyk et al, in preparation, 2012 Estimate of HIV+ unknown went from 50% [38-59%] in 1996 to 14% [0 – 28%] in 2009 Estimate of HIV+ unknown went from 50% [38-59%] in 1996 to 14% [0 – 28%] in 2009 We used pVL ≤40c/mL x2, thus overall supp rate is: 35% [30% - 40%]. This becomes 51% & 60% if a single pVL<50 or <500c/mL are used. Supp rate: 35% [30% - 40%] for pVL ≤40c/mL x2. Supp rate: 51 & 60% for a single pVL<50 or <500c/mL, respectively.

Programmatic Compliance Score • Assesses the impact of non-compliance with HIV treatment guidelines on all-cause mortality • PCS components include: • Baseline CD4 > 200/mm3 • Three CD4 in 1st year • Three VL in 1st year • Baseline resistance • Recommended HAART • Undetectable pVL at 9 months • Failure to meet a given component add one to the score • PCS predicts mortality Lima et al.

TasP Monitoring in the Real World • In a perfect world, all HIV infected individuals would follow the same pathway in the spectrum of engagement into care: • In the real world, there is attrition between each of these steps and individuals are often lost-to-follow-up. • Understanding the attrition points (leakage), and their causes are essential to optimize the effectiveness of TasP. • This can only be achieved by comprehensively monitoring standardized metrics, on a longitudinal basis and accounting for multiple sources of bias and heterogeneity (i.e.: geographic, socio-demographic, risk factors, etc).
