Questions have been raised as to whether reported treatment figures reaching such high coverage are reliable. Sample surveys are proposed as the method of choice for \u201cvalidating\u201d reported coverage figures. The purpose of this study was to compare the district-level MDA coverage reported by programs with contemporaneous surveys of randomly selected respondents living in those same districts. Over an 8-year period, 19,219 households were selected using multistage random sampling; 38,433 adult male and female heads of those households were asked about their recent ivermectin MDA treatment experience. District coverage reports were considered \u201caccurate\u201d if they fell within the 95% CIs determined by the corresponding district\u2019s survey. Ninety-eight treatment rounds were evaluated over an 8-year period. Overall, the reported coverage of 96.5% (range: 68\u2013100%) was significantly higher than the 92.5% surveyed coverage (range: 62.1\u201399.6%, 95% CI: 91.9\u201393.2%). However, only 20% of districts reported significantly higher coverage than surveys, 68% of district program reports were judged as accurate, and 12% of districts reported significantly lower coverage figures than their corresponding surveys. Eighty-eight percent of districts reported coverage \u2265 90% threshold for success, compared with 97% of surveys that included 90% in their 95% CIs. We conclude that when analyzed statistically at the district level, most surveys verified the reported coverage.<\/jats:p>","DOI":"10.4269\/ajtmh.18-0680","type":"journal-article","created":{"date-parts":[[2019,3,26]],"date-time":"2019-03-26T07:01:08Z","timestamp":1553583668000},"page":"1208-1215","source":"Crossref","is-referenced-by-count":8,"title":["Comparison of Reported and Survey-Based Coverage in Onchocerciasis Programs over a Period of 8 Years in Cameroon and Uganda"],"prefix":"10.4269","volume":"100","author":[{"given":"Moses N.","family":"Katabarwa","sequence":"first","affiliation":[{"name":"The Carter Center, Atlanta, Georgia;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emily","family":"Griswold","sequence":"additional","affiliation":[{"name":"The Carter Center, Atlanta, Georgia;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peace","family":"Habomugisha","sequence":"additional","affiliation":[{"name":"The Carter Center, Kampala, Uganda;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Albert","family":"Eyamba","sequence":"additional","affiliation":[{"name":"Odza Center, Yaounde, Cameroon;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edson","family":"Byamukama","sequence":"additional","affiliation":[{"name":"The Carter Center, Kampala, Uganda;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philippe","family":"Nwane","sequence":"additional","affiliation":[{"name":"Centre de Recherche sur les Filarioses et Autres Maladies Tropicales (CRFilMT), Yaounde, Cameroon;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Annet","family":"Khainza","sequence":"additional","affiliation":[{"name":"The Carter Center, Kampala, Uganda;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lauri","family":"Bernard","sequence":"additional","affiliation":[{"name":"The Carter Center, Atlanta, Georgia;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Weiss","sequence":"additional","affiliation":[{"name":"Emory University, Rollins School of Public Health, Atlanta, Georgia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frank O.","family":"Richards","sequence":"additional","affiliation":[{"name":"The Carter Center, Atlanta, Georgia;"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2795","reference":[{"key":"b1","series-title":"Ann Trop Med Parasitol","first-page":"S75","article-title":"Monitoring community-directed treatment programmes for sustainability: lessons from the African Programme for Onchocerciasis Control (APOC)","volume":"96","author":"Amazigo","year":"2002"},{"key":"b2","series-title":"Ann Trop Med Parasitol","first-page":"61","article-title":"Implementing community-directed treatment with ivermectin for the control of onchocerciasis in Uganda (1997\u20132000): an evaluation","volume":"96","author":"Katabarwa","year":"2002"},{"key":"b3","series-title":"Am J Trop Med Hyg","first-page":"216","article-title":"Drug coverage surveys for neglected tropical diseases: 10 years of field experience","volume":"87","author":"Worrell","year":"2012"},{"key":"b4","series-title":"Ann Trop Med Parasitol","first-page":"S41","article-title":"The challenges of community-directed treatment with ivermectin (CDTI) within the African Programme for Onchocerciasis Control (APOC)","volume":"96","author":"Amazigo","year":"2002"},{"key":"b5","series-title":"Bull Soc Pathol Exot","first-page":"188","article-title":"Elimination or control of the onchocerciasis in Africa?
