To assess and compare the effectiveness of ivermectin distributors in attaining 90% treatment coverage of the eligible population with each additional health activity they take up.
Random sampling was applied every year to select distributors for interviews in community-directed treatment with ivermectin (CDTI) areas of Cameroon and Uganda. A total of 288 in 2004, 357 in 2005 and 348 in 2006 distributors were interviewed in Cameroon, and 706, 618 and 789 in Uganda, respectively. The questions included treatment coverage, involvement in additional activities, where and for how long these activities were provided, and whether they were supervised.
At least 70% of the distributors in Cameroon and Uganda during the study period were involved in CDTI and additional health activities. More of the distributors involved in CDTI alone attained 90% treatment coverage than those who had CDTI with additional health activities. The more the additional activities, the less likely the distributors were to attain 90% treatment coverage. In Uganda, distributors were more likely to attain 90% coverage (P < 0.001 if they worked within 1 km of their homesteads were selected by community members, worked among kindred, and were responsible for <20 households.
Additional activities could potentially undermine the performance of distributors. However, being selected by their community members, working largely among kindred and serving fewer households improved their effectiveness.
评估和比较依维菌素分发者开展每一项额外卫生活动对目标人群 90%治疗覆盖率的影响。
在喀麦隆和乌干达社区定向治疗中依维菌素(CDTI)地区,每年采用随机抽样选择分发者进行访谈。2004 年共访谈了 288 名分发者,2005 年为 357 名,2006 年为 348 名;2004 年至 2006 年,乌干达分别访谈了 706、618 和 789 名分发者。问题包括治疗覆盖率、参与额外活动、这些活动的提供地点和持续时间,以及是否有监督。
在研究期间,喀麦隆和乌干达至少有 70%的分发者参与 CDTI 和额外卫生活动。与单独参与 CDTI 的分发者相比,同时参与 CDTI 和额外卫生活动的分发者达到 90%治疗覆盖率的比例较低。额外活动越多,分发者达到 90%治疗覆盖率的可能性就越小。在乌干达,分发者更有可能达到 90%的覆盖率(P<0.001):如果他们在距离家园 1 公里范围内工作、由社区成员选择、在亲缘群体中工作以及负责的家庭少于 20 户。
额外活动可能会影响分发者的表现。然而,由社区成员选择、主要在亲缘群体中工作以及服务的家庭较少,会提高分发者的效率。
