Brief summary
All households in three zones in Zambia's Eastern Province were invited to attend a community point distribution of insecticide treated bed nets (ITNs). Households were then randomized to different intervals for a community health worker (CHW) hang-up visit.
Detailed description
Households were asked to attend a community point distribution of ITNs in one of three zones in Zambia's Eastern Province. Households that had been registered to receive ITNs were then randomized to one of five groups that received a CHW visit at different intervals. Group 1 was visited 1-3 days after distribution, group 2 was visited 5-7 days after, group 3 was visited 10-12 days after, group 4 was visited 15-17 days after, and group 5 did not receive a hang-up visit. Groups 1-4 were categorized as having received a hang-up visit and group 5 was categorized as not having received a hang-up visit. All households in all five groups were visited at 7-11 weeks after the distribution and again at 5-6 months after the distribution to assess short- and medium-term ITN retention and usage.
Interventions
OTHERCommunity point distribution
Households were invited to a central location in their community (i.e. school, church, etc) where they received their allotment of ITNs (one per sleeping space, as pre-registered ahead of study activities). Households were provided with malaria prevention messaging at the distribution. They were called up one-by-one in front of other members of the community to mitigate misrepresentation of households.
OTHERCommunity health worker hang-up visit
CHWs visited households to take stock of how many ITNs that were distributed during the distribution were hung and to hang any unhung ITNs.
