A knowledge co-production strategy to address systematic non-compliance with MDA for Lymphatic Filariasis in Leogane, Haiti

The researchers propose taking a novel approach to increase coverage and reach previously neglected populations by engaging non-compliant individuals in devising a more effective strategy through a technique called knowledge co-production. The researchers plan to address the following questions:

  1. Can an intervention package co-produced with systematically non-compliant individuals result in increased MDA coverage between the 2019 and 2020 LF MDA rounds?
  2. Who and where are the systematic non-compliers in Leogane and Gressier?
  3. What are the reasons motivating systematic non-compliance?
  4. Is MDA non-compliance associated with hotspots of LF transmission?

The researchers plan the following activities:

  1. A household cluster survey with 1300 individuals of all ages. This will define coverage in the past MDA and identify non-compliant individuals. In addition, ‘hidden’ non-compliers (NCs) will be located by a networking approach (respondent-driven sampling [RDS]).
  2. All NCs will then be eligible to be selected into groups of 10 by age (18-25; 26-50; >50), sex (M, F) and demography (urban/rural). These 12 groups will each work with the national health team to devise new approaches to the non-compliance issue. These will be put into place for the 2020 MDA and then assessed by the co-production strategy groups. After the 2020 MDA a second survey will occur to assess impact.
  3. The relationship between non-compliance and hotspots will be assessed using spatial analysis and defined serologically (FTS and DBS for antibodies) in collaboration with CDC.

Investigating the role of drug delivery strategy in MDA drug coverage

Haiti, like many other countries, has made considerable progress in the elimination of lymphatic filariasis. To date, 118 out of 140 communes have passed TAS and stopped MDA. However, little is understood about why some communes have persistent transmission despite five or more rounds of MDA. The proposed study aims to identify alternative approaches to MDA that may help to increase access, uptake, and coverage, particularly for individuals who typically do not comply with MDAs. This cluster-randomized design will test a novel approach (door to door strategy) against the standard health post-based delivery method. Additionally, the study aims to identify non-compliant individuals and better understand their reasons for non-participation. Furthermore, a cost analysis will be undertaken as part of this study to understand the potential implications for the country program should the door-to-door strategy prove effective in reaching higher numbers of people.
