Abstract
Children of recently migrated families in slums in Dhaka, Bangladesh have lower immunization rates and higher rates of death from respiratory illnesses due to delays in seeking qualified health care services. Recently relocated families are in general poorer, less-educated, and less-knowledgeable about nearby health services. Our pilot study aims to develop and test an innovative potentially low-cost intervention in Dhaka slums using word-of-mouth information dissemination to connect community newcomers to nearby immunization centers and qualified child health services.

Interventions
Intervention(s)
Our main research question is whether a peer-to-peer communication intervention can be used to change child health services knowledge and health seeking behavior of mothers living in urban slums, particularly mothers who have recently relocated to slums. We will pilot a community-based intervention to promote communication among residents about nearby qualified health services and use of these services. We developed behavior change communication (BCC) materials comprised of posters, leaflets, and stickers that show the closest qualified child health and immunization centers with addresses/directions, available services, and hours of service. Our BCC materials also teach basic health education about routine childhood immunizations and about signs of severe diarrhea, pneumonia, and malnutrition that should prompt urgent seeking of health services. We are gathering influential community members including slum landlords/compound managers, school teachers, imams, traditional healers, and local health service providers and asking them to help promote our BCC materials to mothers. We will also hold community meetings with mothers themselves and encourage them to use and share information from our intervention.

Primary Outcomes
Primary Outcomes (end points)
Our primary outcome will be uptake and feasibility of our pilot intervention. Secondary outcome variables will be quantitative measurements of: exposure to our intervention among mothers, proportion of mothers with knowledge of nearby qualified child health and immunization services, and self-reported change in health seeking behavior.

Experimental Design
Experimental Design
Our first phase was formative qualitative research in two slums in Dhaka, Bangladesh. Our formative research included in-depth interviews with recently relocated and residentially stable mothers with children under 5 years of age, social network analysis of mothers and their community support, and key informant interviews with slum landlords/compound managers and local health providers. We then developed our community intervention and materials to provide information on nearby qualified child health and immunization services: signs and symptoms of severe illness, address of nearby health and immunization centers, and hours of services. Our intervention phase will be conducted in two different slums in Dhaka, Bangladesh. We will pilot our peer-to-peer communication intervention, examine feasibility, and measure pre-intervention and post-intervention knowledge about child health services among mothers.

Experiment Characteristics
Sample size: planned number of clusters
This study is a pilot intervention and not a cluster-randomized controlled trial. We have two intervention study areas.
Sample size: planned number of observations
90 pre-intervention surveys and 90 post-intervention surveys (not the same participants)
Sample size (or number of clusters) by treatment arms
We have chosen 2 slum areas for intervention, and there are approximately 800-900 total households who will receive our pilot intervention.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
