The Evidence About What Works: Our Response to TNR

How much evidence is enough before we know that a global development intervention works for people? How much evidence is enough to know that a program is worth scaling to millions of people because it works and benefits lives across multiple settings and contexts?

These are great questions that Michael Hobbes raises in an article in the most recent issue of The New Republic. In fact, we at Evidence Action think a lot about this. Our mission is to scale programs that have been proven to work so they benefit millions of people.

Unfortunately, Mr. Hobbes used a poor example to raise these questions by focusing on deworming. In the case of mass deworming of children and our Deworm the World Initiative, the policy has followed the (rigorous) evidence. Deworming has a well-proven, clear causal chain from intervention to effect.

Mass Deworming: It’s Good Public Policy

Intestinal worm infections are among the most widespread diseases globally today that affect more than a billion people especially in low-income countries. These parasites--roundworms, hookworms, and whipworms--affect especially school-age children, causing malnutrition, fatigue, and even organ damage and internal bleeding. Periodic and presumptive mass treatment of every child is inexpensive, considered very safe, and is recommended WHO policy in areas where worms are endemic. A number of countries have made school-based deworming part and parcel of their national health and education policies.

Yet, some have argued that the WHO recommendation of mass treatment of everyone in an affected area is not supported by enough evidence.

In a new paper, authors Amrita Ahuja, Sarah Baird, Michael Kremer et al. argue that mass deworming treatment is not only effective for children, supported by ample and growing rigorous evidence, but also smart educational and economic policy for endemic countries.

Evidence Action Joins the STH Coalition

Evidence Action is pleased to announce that we have joined the STH Coalition, a new group of organizations focused on reducing the public health threat of soil-transmitted helminths (STH) worldwide. Soil-transmitted helminths --intestinal parasites such as roundworm, hookworm, and whipworm-- affect the health, education, and livelihoods of over one billion people worldwide. The World Health Organization has set a target of reaching 75% of all at-risk children by 2020; yet only 32% of children received deworming drugs in 2012. Given the magnitude and complexity of the challenge, we at Evidence Action believe that a cross-sectoral, collaborative approach to addressing STH is essential.
