DeWorm3 Implementation Science

The DeWorm3 Project is a series of hybrid trials testing the feasibility of interrupting the transmission of soil transmitted helminths (STH), while conducting implementation science research that contextualizes clinical research findings and provides guidance on opportunities to optimize delivery of STH interventions.

The purpose of DeWorm3 implementation science studies is to ensure rapid and efficient translation of evidence into practice. Research methods include: (1) stakeholder mapping and network analysis, (2) qualitative research, (3) structural readiness surveys, (4) process mapping, and (5) economic evaluation (costing and cost-effectiveness). 

 Implementation science research aims include:

1)To systematically identify stakeholders influencing standard of care targeted and community-wide MDA and map their potential role and involvement in scale-up of community-wide MDA for STH.

2)To identify implementation-related barriers and facilitators to community-wide MDA for STH from the perspective of various stakeholders.

3)To quantify the readiness of the health system to deliver community-wide MDA for STH programs.

4)To map the intervention delivery process and identify any discrepancies between planned and implemented activities in order to optimize the trial intervention.

5)To compare the financial and economic costs and incremental cost-effectiveness of community-wide and targeted MDA for STH in the short- and long-term.

Starworms study

The Starworms project aims to strengthen the monitoring and surveillance of drug efficacy and anthelmintic resistance in soil-transmitted helminth (STH) programs. As such, it will support deworming programs in their quest to eliminate STHs as a public health problem by 2020. The specific objectives are (1) to validate diagnostic tools to monitor drug efficacy and the spread of anthelmintic resistance, (2) to create a surveillance system that monitors the global patterns of drug efficacy and spread of anthelmintic resistance in STH programs, and (3) to develop supporting tools to plan, analyze and follow up on surveys on drug efficacy and the spread of anthelmintic resistance.

STH Diagnostic Comparison: PCR vs. Kato-Katz, Uganda

To determine if a standardized multi-parallel-PCR assay is a more sensitive diagnostic tool for detecting Hookworm (Ancylostoma duodenale and Necator americanus), Trichuris trichiura, Ascaris lumbricoides, Strongyloides stercoralis, and Schistosoma mansoni prevalence compared to the Kato-Katz stool test.
