Assessing the Feasibility of Continuous Net Distribution in Kenya using Community Based Approach
Background • Malaria control strategies are based on four principles • Early diagnosis and treatment • Use of effective medicines • Sustainable preventive measures such as vector control- use of long-lasting insecticidal nets (LLINs)/IRS • Detection, containment and prevention of epidemics
Approaches to increasing net coverage • Use of LLINs have potential of saving half a million child deaths each year • Sustained coverage and use of LLINs remains low • Efforts to increase coverage include: • Social marketing • Catch-up -provision of free nets through clinics/ vaccination campaigns • Keep-up-combined strategy through provision of nets routinely to pregnant-women and children through public health clinics or commercial outlets/vouchers
Why a community approach? • Shift from vulnerable populations to universal coverage • Universal coverage- ratio of at least one LLIN for every two household members • Sustaining universal coverage require innovative ways • Continuous distribution systems are crucial to maintaining universal coverage • Operational studies indicate the potential of using a community based model of sustaining universal coverage
Null Hypothesis • Community based distribution of nets have no effect in sustaining universal coverage
General Objective • To test the feasibility of sustaining universal coverage achieved during the mass net distribution through community based distribution
Specific Objectives • To estimate the current number of nets per household in settings where mass distribution was implemented in 2011 • To identify the number of nets in the household that need replacement • To pilot and document the feasibility of using community based LLIN distribution schemes in maintaining universal coverage • To assess whether community based redistribution schemes achieve higher utilization rates
Proposed intervention components Component 1: Establishment of HH registers • CHWs under the supervision of CHEWS will develop a baseline village register containing HH details Component 2: Training of CHW/CHEW • Identification of CHWs & CHEWS • Training and sensitization on continuous LLINs distribution, their expected roles and responsibilities
Proposed intervention components Component three: Need determination • LLIN need determination at Household level • HHH approaches CHW for verification • CHW gives a coupon to HHH to redeem a net from facility Component four: Advocacy and IEC strategies • PHTs to conduct community awareness programs and integrate messages into health talks • Use of active district ITN advocacy/ information, education and communication (IEC) groups
Evaluation approach What do you want to measure? How sure do you want to be?
Study design • Quasi experimental utilizing a plausibility assessment of a before and after study with a control. • Mixed methods- • Quantitative- to assess the number of nets within the HH/ replacement, utilization of nets • Qualitative -to assess the feasibility of using community based approaches to distribute the nets
Project sites • Project site : selected community units in Samia District of Busia County • Selection criteria : • Communities with a functional community health unit • similar malaria epidemiological profile, • Geographical buffer of about 20 km apart; • Has had mass net distribution taking place, • Malaria endemic with a prevalence of above 38%. • The district will be divided into intervention and control sites.
Sample size determination • Expected effect: 10-20%, • Cluster design approach-using a design effect of 2 • 95% confidence interval and 80% power, • Estimated universal coverage 59.6% in western Kenya (Post Mass Net Evaluation report) • Estimated sample size will be 876 per arm giving an estimated sample size of 1752 HHs in the two study sites
Data analysis • Quantitative data from the HHs survey will be collected using android enabled phones/PDAs and submitted to a central server each day. • Data verification, cleaning and analysis will be conducted using STATA version 11 • Using USAID- Tool kit to track community –NetCalc version 2 to estimate coverage • Qualitative data will be stored and managed using Nvivo10
