The Anchored Multiplier calculator synthesizes multiple estimates of the size of a population into a single “consensus” estimate. The Anchored Multiplier uses a Bayesian modeling framework to combine empirical estimates with a prior belief (e.g., an estimate from a stakeholder, a previous study or extrapolation from the literature). Data input can take the form of raw numbers or population percentages. The calculator will fit the data input to a beta probability distribution that reflects the data point’s certainty (i.e., strength). Stronger data points (those with narrower confidence intervals) will have a greater influence on the final estimate than weaker data points (those with wider confidence intervals).

The Entomological Surveillance Planning Tool, piloted in Zanzibar in 2009, guides countries in thoroughly assessing the technical, operational and financial feasibility of malaria elimination. Our Malaria Elimination Initiative (MEI) and the Clinton Health Access Initiative used this strategic decision-making and planning tool to assess the feasibility of eliminating malaria in Senegal/Gambia and Hispaniola. MEI is now supporting Rwanda in assessing the feasibility of achieving pre-elimination in the short term.
MEI partnered with the World Health Organization, Clinton Health Access Initiative, Johns Hopkins University and Imperial College to develop the ESPT.
Contributors to the Palgrave Handbook of Global Health Data Methods for Policy and Practice created a website to assist students, practitioners, policymakers and the general public understand how data can be collected, analyzed and disseminated to improve global health. The website contains valuable information from the book and links to additional resources.
We have developed a series of HIV surveillance training manuals to help scientists, officials and health professionals gather and produce high-quality, reliable data that will inform policy and programs to improve the health of HIV-affected populations and reduce the spread of the virus.
This toolbox provides training, technical assistance and active mentoring in various effective methodologies for domestic and international surveillance. This toolbox is for governments, nongovernmental organizations and private researchers who wish to implement integrated bio-behavioral surveillance surveys for key populations at higher risk for HIV infection.
MERFAT enables programs to gather information on malaria cases and controls and identify which factors are associated with the risk of infection. Identifying risk factors is necessary to target high-risk populations; this can be difficult in elimination settings because of the very low numbers of infections at any given time.
The oxygen calculator was created by multiple collaborators of the Open Critical Care Project with initial funding from USAID-STAR and the IGHS Center for Health Equity in Surgery and Anesthesia (CHESA). The tool is designed for educational purposes.
PROMPT is an easy and adaptable approach for national malaria programs to strengthen pharmacovigilance for the safe introduction of primaquine, an antimalarial drug. PROMPT’s flexible platform supports passive and active surveillance, allowing adaptability to various program capacities. Data collected from PROMPT is fed into a global repository to promote data sharing across multiple stakeholders and diverse epidemiological settings needed for a broader analysis of primaquine safety data.
This simple monitoring and evaluation tool assesses the completeness and timeliness of active surveillance and response and informs malaria programs about how and where efficiency gains can be made. It examines the key components of active surveillance activities, identifies and evaluates the strengths and gaps of the active surveillance program, and assesses the costs of conducting reactive case detection. This tool has been used in South Africa, China and other countries in southern Africa and the Asia Pacific.
