Abstract: Self-management of risk behaviors is a cornerstone of future population health. Using mobile phones for routine self-monitoring is a cost-efficient strategy for self-management. Despite benefits, new challenges are also introduced. Costs, logistics, and appropriateness of mobile phones for the intended population need to be considered. Daily reports that are common to mobile data collection versus retrospective self-reports that are common to traditional studies offer new opportunities to provide participant feedback and model behavior patterns. At the same time, new challenges are introduced in data management, presentation, user uptake, and analysis. In the first presentation, we will cover mobile phone-based study design scenarios and issues. The second presentation will cover analytic strategies to examine participant preferences using conjoint analysis around this new technology and time-series analyses to model daily reports.
Armed with bracing logic, wit and her “public-health nerd” glasses, Elizabeth Pisani reveals the myriad of inconsistencies in today’s political systems that prevent our dollars from effectively fighting the spread of HIV. Her research with at-risk populations — from junkies in prison to sex workers on the street in Cambodia — demonstrates the sometimes counter-intuitive measures that could stall the spread of this devastating disease.

MAR-14-12 At the 19th Conference on Retroviruses and Opportunistic Infections (CROI) [external disclaimer] last week, Dr. Ron Valdiserri, Deputy Assistant Secretary of Health for Infectious Diseases, spoke with Dr. Michael Horberg, Director of HIV/AIDS for Kaiser Permanente and a member of the Presidential Advisory Council on HIV/AIDS (PACHA). They discussed the paper Dr. Horberg presented at CROI on the impact of missed office visits on HIV outcomes and mortality. This paper offers important insight into our efforts to address improvements in the continuum of HIV care. (From Miguel Gomez via blog.aids.gov) |
Hans Rosling unveils new data visuals that untangle the complex risk factors of one of the world’s deadliest (and most misunderstood) diseases: HIV. He argues that preventing transmissions — not drug treatments — is the key to ending the epidemic.
For the last eight years, pop singer Annie Lennox has devoted the majority of her time to her SING campaign, raising awareness and money to combat HIV/AIDS. She shares the experiences that have inspired her, from working with Nelson Mandela to meeting a little African girl in a desperate situation.
In sub-Saharan Africa, HIV infections are more prevalent and doctors scarcer than anywhere else in the world. With a lack of medical professionals, Mitchell Besser enlisted the help of his patients to create mothers2mothers — an extraordinary network of HIV-positive women whose support for each other is changing and saving lives.
The iPrEx trail results published in NEJM at the end of December were hailed as the start of a new era in the prevention of HIV infection. iPrEx studied pre-exposure prophylaxis (PrEP)— the regular use of antiretroviral medications by uninfected individuals—in a sample of MSM in several countries. Dramatic as these results were—PrEP reduced HIV incidence by 44% in the clinical trial—we need to be cautious about how we implement PrEP lest we abandon proven prevention strategies that can prevent greater numbers of HIV infections with the same level of expenditure as PrEP.
PrEP has been called the “next big thing” and Bill Gates has said that if the trials are successful PrEP distribution programs could start in 2012 in developing countries (Bennett 2010). Before launching any widespread dissemination of PrEP, policy makers need to decide how PrEP fits into an overall strategy for HIV prevention. PrEP is very costly because it depends on ARVs actively used in HIV treatment. Although these drugs would be less expensive in developing countries, developing countries’ ability to pay for drugs is also correspondingly lower. PrEP’s high cost means that its widespread dissemination would likely displace other prevention strategies, such as condom use, post-exposure prophylaxis (PEP), microbicides (CAPRISA) or Testing plus Linkage to Care (TLC+), that could prevent greater numbers of infections at lower cost.
Modeling suggests that compared to PrEP, TLC+ is more cost effective (Long; Paltiel; Walensky). The economic argument is supported by an ethical argument: shouldn’t our first priority be to provide ARVs to all who already are infected with HIV, rather than those the uninfected? Indeed, I believe that the ethical approach is to prevent as many new infections as possible with given tools. This will require us to prioritize our prevention strategies and make the most effective strategies the first line of defense.
I am tired of researching HIV disease. A recent CDC Funding Opportunity calls for a “National Coalition to Enhance STD/HIV Prevention through Promotion of a Holistic Approach to Health and Wellness.” It asks for communities to think about addressing HIV not just as a singular challenge, but from an approach of community wellness. And not simply for HIV, either, but includes the integration of diagnostic and prevention services for various STDs as well as Hepatitis B and C. It makes a strong argument for program integration and service collaboration to attack a range of challenges in a holistic manner. It is time for this approach.
Yet, there are going to have to be REALLY innovative approaches if this is to succeed. There will be major potential risk and benefits.
Ryan White funding is intended to secure the uninsured (and underinsured) right to comprehensive HIV treatment and access to medications. In our current budget crises, I do not expect HIV to remain carved out. The chance is great that Ryan White legislation may not be reauthorized two years from now. Persons living with HIV may be mainstreamed into the patient-centered medical homes and insurance exchanges to be set up by states. In California, the five-year old fiscal crisis has already eliminated many of the existing funding for HIV prevention (with the exception of HIV testing). Waiting lists for AIDS Drug Assistance Programs have increased in many states, and currently over 6,000 people are on them nation-wide.
Agreeing to mainstream HIV into community wellness may be encouraging this scenario, so our best long-term strategy may be accepting the inclusion of HIV in overall health reform scenarios like medical homes rather than fighting for a carved out piece of a shrinking pie.
If we are focused on wellness, HIV-specific funding may disappear. Many of the functions previously funded by Ryan White and CDC, for everything from confidential HIV testing sites to comprehensive case management of persons living with HIV may disappear. This places all persons at high risk for HIV, especially men-who-have-sex-with-men (MSM) and MSM/W.
Perhaps mainstreamed funding may have some community benefits. All political pundits are calling for disruptive, radical change. Chronic diseases, such as HIV, require community support. Wellness initiatives must be focused on improving the health of a community. Safety nets are likely to be created by social networks of individuals who form communities: these communities may be the “novel” path to wellness and the end of stigma towards HIV and MSM.
In the early epidemic, MSM supported each other. The passion to save our friends drove many of the researchers, providers, and administrators to enter HIV research. The long…long…process of trying to beat HIV may now lead us to back to community. If funding for all ancillary services is cut, the MSM and lesbian community may again be mobilized to protect and support each other’s search for health (not serve their HIV disease).
Funding, treatments, and opportunities have changed. Will the current fiscal crises drive us to help each other more?
