Testing a Scalable Model of the Cholera Hospital-Based Intervention for 7 Days (CHoBI7)
Sponsor: Johns Hopkins Bloomberg School of Public Health
Summary
The findings from previous recent randomized controlled trials of The Cholera Hospital Based Intervention for 7 Days (CHoBI7) demonstrated that this intervention was effective in significantly reducing symptomatic cholera infections, diarrheal disease, and stunting among young children in intervention households, and had significant sustained impacts on handwashing with soap behaviors and improved water quality 12 months post intervention. Therefore, the investigators next step in the transition to scale is to: (1) To tailor the CHoBI7 program for delivery in rural health facilities and market test the CHoBI7 Program to determine the feasibility of providing a modified water, sanitation, and hygiene (WASH) package with only a soapy water bottle and chlorine tablets in both urban and rural settings through formative research and engagement of key stakeholders (Formative Research Phase); and (2) To evaluate the effectiveness of delivering the CHoBI7 program in district hospitals and sub-district health complexes in rural areas in terms of increases in WASH behaviors and decreases in diarrheal disease by conducting a randomized controlled trial (RCT) (Intervention Implementation and Evaluation Phase).

Standard Recommendation
Standard recommendation given by government of Bangladesh on the use of oral rehydration solution (ORS) and a flyer on water treatment and handwashing with soap given at the health facility during the time of diarrhea patient treatment.
CHoBI7 Scale-Up Program
Health promoter delivery of handwashing with soap, water treatment, and safe water storage module in the health facility to diarrhea patients and the patient's household members during the time of treatment. This module includes video testimonials from diarrhea patient households on how the patient benefits from adhering to the promoted behaviors, and a demonstration on how to construct homemade handwashing washing stations. This in-person module is reinforced by weekly voice, interactive voice response, and text messages for three months sent to the mobile phones of diarrhea patient household members from a doctor at diarrhea ward at local hospital.
