NHAS Goals for Reducing HIV
Incidence
NHAS Goals for Improving
Treatment Access
NHAS Goals for Reducing
Health Disparities
Key implications of NHAS
(from Holtgrave, JAIDS 2010)
• How will epidemic be changed if goals are met?
– Prevent roughly 75,800 infections (2010-2015)
– Prevent roughly 237,700 infections (2010-2020)
– 2015 prevalence without NHAS roughly 1.481M and with
NHAS roughly 1.407M
• Approx. 218,900 more people on care and treatment
Key Implications of NHAS -- continued
(from Holtgrave, JAIDS 2010)
• Cost of NHAS in expanded funding (be it new, redirected, or
new private sector)
– Total across years through 2015
• Roughly $15.2B need to achieve NHAS
– Approx.. $2.1B for prevention
– Just under $1B for housing (to achieve NHAS goal)
– Remainder for care and treatment (approx. $12.2B)
» 43% is due to expanded awareness
» 57% due to expanded coverage
Key Implications of NHAS - continued
(from Holtgrave, JAIDS 2010)
– However, investing in NHAS could save money
– Medical costs offset by HIV infections averted through expanded
prevention efforts
– Net present value of medical care costs saved due to prevention efforts: $17.981B
– Savings larger than investments needed (cost saving)
– Bend the cost curve by bending the incidence curve
– Choosing to not expand prevention efforts is the MORE expensive
policy option

Costs, Consequences and Feasibility of
Strategies for Achieving the Goals of the
NHAS – 2012 analysis
• Is it still epidemiologically feasible to attain the incidence and
transmission rate reduction goals of the U.S. National
HIV/AIDS Strategy (NHAS) by 2015?
• If so, what costs will be incurred in necessary program
expansion, and will the investment be cost-effective?
• Would substantial expansion of prevention services for
persons living with HIV (PLWH) augment the other strategies
emphasized in the NHAS in terms of effectiveness and costeffectiveness?

Summary results comparing HIV service
implementation scenarios one at a time to a
flat transmission rate comparison condition
• The incidence reduction and transmission rate reduction NHAS goals are met in three
of the eight scenarios (S694YFSC, S807YMC, and S807YFSC).
• The incidence reduction and transmission rate reduction NHAS goals are narrowly
missed in two other scenarios (S694YMC and S807NFSC).
• The best cost-utility ratios are obtained when both diagnostic efforts and prevention
services for PLWH are scaled up.
• The least effective scenario is to meet the care goal of the NHAS but fail to achieve the
awareness of seropositivity goal or fully scale up risk reduction services for PLWH.
• Care expansion alone averts the least number of infections, and the resultant cost-utility
ratio is over the often-used $100,000 cost-effectiveness standard.
• Inclusion of enough expansion of testing services to achieve the seropositivity
awareness goal, inclusion of fully scaled-up risk-reduction interventions for PLWH, or
both all serve to substantially improve performance on the outcome measures and to
move the results into a range easily considered cost-effective.

National HIV/AIDS Strategy
• Simply waiting for expansion of
care services in 2014 and 2015
will not be enough to reach
incidence and transmission rate
reduction NHAS goals
• Investment in diagnostic services
and prevention services for
PLWH (in addition to care and
housing services) enables us to
reach those goals
• But very substantial progress
toward investing in these
services must be made in FY13
• Otherwise, the window on
achieving the NHAS goals will be
closed
We Must Avoid…
…But Time Has Almost Run Out
