Cost-effectiveness of different strategies to monitor adults on antiretroviral treatment: a combined analysis of three mathematical models.
Lancet Glob Health
PUBLISHED: 08-09-2014
Show Abstract
Hide Abstract
WHO's 2013 revisions to its Consolidated Guidelines on antiretroviral drugs recommend routine viral load monitoring, rather than clinical or immunological monitoring, as the preferred monitoring approach on the basis of clinical evidence. However, HIV programmes in resource-limited settings require guidance on the most cost-effective use of resources in view of other competing priorities such as expansion of antiretroviral therapy coverage. We assessed the cost-effectiveness of alternative patient monitoring strategies.

Health benefits, costs, and cost-effectiveness of earlier eligibility for adult antiretroviral therapy and expanded treatment coverage: a combined analysis of 12 mathematical models.
Lancet Glob Health

Show Abstract
Hide Abstract
New WHO guidelines recommend initiation of antiretroviral therapy for HIV-positive adults with CD4 counts of 500 cells per ?L or less, a higher threshold than was previously recommended. Country decision makers have to decide whether to further expand eligibility for antiretroviral therapy accordingly. We aimed to assess the potential health benefits, costs, and cost-effectiveness of various eligibility criteria for adult antiretroviral therapy and expanded treatment coverage.

The potential effects of changing HIV treatment policy on tuberculosis outcomes in South Africa: results from three tuberculosis-HIV transmission models.
AIDS
PUBLISHED: 01-29-2014
Show Abstract
Hide Abstract
Many countries are considering expanding HIV treatment following recent findings emphasizing the effects of antiretroviral therapy (ART) on reducing HIV transmission in addition to already established survival benefits. Given the close interaction of tuberculosis (TB) and HIV epidemics, ART expansion could have important ramifications for TB burden. Previous studies suggest a wide range of possible TB impacts following ART expansion. We used three independently developed TB-HIV models to estimate the TB-related impact of expanding ART in South Africa.

Non-monotonicity in the episodic random utility model.
Health Econ
PUBLISHED: 06-17-2010
Show Abstract
Hide Abstract
The time trade-off (TTO) is widely used in population-based surveys to estimate health-state valuations. Typically, respondents may characterize states as being better than or worse than dead. However, worse-than-dead responses can produce strongly negative mean values, so various analytic transformations of these responses have been suggested. The episodic random utility model (eRUM), operationalized using a linear regression estimator, was proposed as an alternative to these transformations, in part because of its theoretical appeal. We analyzed the eRUM estimators mathematical properties and found that it violates monotonicity under certain patterns of survey responses, such that improvement in some individual valuations would imply a lower overall valuation for a given health state. Consequently, it is possible that orderings of alternative strategies based on eRUM valuations could lead a decision-maker to choose a strictly dominated strategy. Re-analyzing data from a large population-based EQ-5D valuation survey in the United Kingdom, we found 27% of all TTO responses (63% of all worse-than-dead responses) met the conditions for violation of monotonicity, and 74% of all respondents had at least one such response. These results present some challenge to the use of the eRUM estimator in generating health-state valuations for population health measurement and economic evaluation.

Cost-effectiveness of routine rapid human immunodeficiency virus antibody testing before DNA-PCR testing for early diagnosis of infants in resource-limited settings.
Pediatr. Infect. Dis. J.
PUBLISHED: 09-26-2009
Show Abstract
Hide Abstract
Infants born to HIV-infected women should receive HIV testing to allow early diagnosis and treatment. Recommendations for resource-limited settings stress laboratory-based virologic assays. While effective, these tests are logistically complex and expensive. This study explored the cost-effectiveness of incorporating initial screening with rapid HIV tests (RHT) into the conventional testing algorithm to screen-out HIV-uninfected infants, thereby reducing the need for costly virologic testing.

Population health impact and cost-effectiveness of tuberculosis diagnosis with Xpert MTB/RIF: a dynamic simulation and economic evaluation.
PLoS Med.
Show Abstract
Hide Abstract
The Xpert MTB/RIF test enables rapid detection of tuberculosis (TB) and rifampicin resistance. The World Health Organization recommends Xpert for initial diagnosis in individuals suspected of having multidrug-resistant TB (MDR-TB) or HIV-associated TB, and many countries are moving quickly toward adopting Xpert. As roll-out proceeds, it is essential to understand the potential health impact and cost-effectiveness of diagnostic strategies based on Xpert.

The determinants of HIV treatment costs in resource limited settings.

Show Abstract
Hide Abstract
Governments and international donors have partnered to provide free HIV treatment to over 6 million individuals in low and middle-income countries. Understanding the determinants of HIV treatment costs will help improve efficiency and provide greater certainty about future resource needs.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
