Article Synopsis
  • The CDC, EPA, and Council of State and Territorial Epidemiologists have been tracking waterborne disease outbreaks since 1971 through the Waterborne Disease and Outbreak Surveillance System (WBDOSS), which reports on the causes and scope of these incidents in the U.S.
  • The report summarizes 48 outbreaks from January 2007 to December 2008, including previously unreported cases, with a focus on outbreaks linked to drinking water and other types of water use.
  • In this period, 36 drinking water-associated outbreaks affected over 4,100 individuals and resulted in three deaths, primarily involving bacterial agents, alongside some viral and parasitic cases.

Background: A recent indirect comparison study showed that sunitinib-refractory metastatic renal cell carcinoma (mRCC) patients treated with everolimus are expected to have improved overall survival outcomes compared to patients treated with sorafenib. This analysis examines the likely cost-effectiveness of everolimus versus sorafenib in this setting from a US payer perspective.

Methods: A Markov model was developed to simulate a cohort of sunitinib-refractory mRCC patients and to estimate the cost per incremental life-years gained (LYG) and quality-adjusted life-years (QALYs) gained.

Background: Personalized medicine requires diagnostic tests that stratify patients into distinct groups that may differentially benefit from targeted treatment approaches. This study compared the costs and benefits of two approaches for identifying those at high risk of developing type 2 diabetes for entry into a diabetes prevention program. The first approach identified high risk patients using impaired fasting glucose (IFG).

Innovation in the field of diagnostic imaging is based primarily on the availability of new and improved equipment that opens the door for new clinical applications. Payments for these imaging procedures are subject to complex Medicare price control schemes, affecting incentives for appropriate use and innovation. Achieving a "dynamically efficient" health care system-one that elicits a socially optimal amount of innovation-requires that innovators be rewarded in relation to the value they add and can demonstrate with evidence.

Background: Measles control has succeeded worldwide, and many countries have substantially reduced incidence and mortality. This has led to consideration of the feasibility of measles elimination in Uganda within the context of global eradication. Before an elimination program is initiated, it is important to consider its potential economic impact, including its cost-effectiveness.

Background: HIV/AIDS clinics in Uganda and other low-income countries face increasing numbers of patients and workforce shortages. We performed a cost-effectiveness analysis comparing a Pharmacy-only Refill Program (PRP), a form of task-shifting, to the Standard of Care (SOC) at a large HIV/AIDS clinic in Uganda, the Infectious Diseases Institute (IDI). The PRP was started to reduce workforce shortages and optimize patient care by substituting pharmacy visits for SOC involving monthly physician visits for accessing antiretroviral medicines.

Rosiglitazone was initially approved for type 2 diabetes monotherapy. We tested health-outcomes modeling as an aid to regulatory decision making by quantifying the incremental net benefit (INB) value of rosiglitazone (relative to a comparator), both at the time of first approval (1999) and at the FDA advisory committee review (2007). Using 1999 data, rosiglitazone was projected to provide an additional 0.

The Patient Protection and Affordable Care Act established a new Patient-Centered Outcomes Research Institute to identify and address research priorities for comparative effectiveness research. Among its many responsibilities, the institute has been charged with setting priorities, developing methodological standards, and communicating research results to decision makers. In this paper we consider how the institute can support the different standards for acceptable evidence used by various government agencies, providers, patients, and other decision makers.

A key to accelerating the appropriate integration of genomic applications into healthcare in the coming decades will be the ability to assess the tradeoffs between clinical benefits and clinical risks of genetic tests in a timely manner. Several factors limit the ability of stakeholders to achieve this objective, including the lack of direct evidence, the lack of a framework to quantitatively assess risk and benefit, and the lack of a formal analytic approach to assess uncertainty. We propose that a formal, quantitative risk-benefit framework may be particularly useful for assessing genetic tests intended to influence health outcomes, and communicating the potential clinical benefits, harms, and uncertainty to stakeholders.
