Cholera-Hospital-Based-Intervention-for-7-days

Study Overview
=================
Brief Summary
-----------------
The Cholera Hospital Based Intervention for 7 Days (CHoBI7) randomized controlled trial for transition to scale aimed to: (1) Develop and evaluate scalable approaches to integrate the CHoBI7 intervention into the services provided for hospitalized diarrhea patients at health facilities in Bangladesh; and (2) Evaluate the ability of the CHoBI7 intervention to lead to a sustained uptake of the promoted hand washing with soap and water treatment behaviors and significant reductions in diarrheal disease over time.

Detailed Description
-----------------
The findings from the recent randomized controlled trial of The Cholera Hospital Based Intervention for 7 Days (CHoBI7) demonstrated that this intervention was effective in significantly reducing symptomatic cholera infections in intervention households, and had significant sustained impacts on hand washing with soap behaviors and improved water quality 12 months post intervention. Next steps to transition to scale were: (1) Develop and evaluate scalable approaches to integrate the CHoBI7 intervention into the services provided for hospitalized diarrhea patients at health facilities in Bangladesh; and (2) Evaluate the ability of the CHoBI7 intervention to lead to a sustained uptake of the promoted hand washing with soap and water treatment behaviors and significant reductions in diarrheal disease over time.

Eligibility Criteria
-----------------
Inclusion Criteria: Diarrhea patients will be defined as patients having acute watery diarrhea three or more loose stools over a 24-hour period in the past three days. Diarrhea patients admitted to ICDDRB Dhaka Hospital or Mugda General Hospital will be eligible for the trial if: have had 3 or more loose stools over the past 24 hours plan to reside in Dhaka for the next 12 months have no basin for running water in their home have a child under five years of age in their household (including themselves) that produced a stool sample at baseline have a working mobile phone in the household. Household members of the diarrhea patient will be eligible for the trial if: they have shared the same cooking pot and resided in the same home with the diarrhea patient for the last three days plan to reside in their current household with the diarrhea patient for the next 12 months Exclusion Criteria: (1) Children in foster care will be excluded from all research study activities.

Intervention Model: Parallel Assignment
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Standard recommendation (ORS)<br>Participants received the standard recommendation on oral rehydration solution use | |
| Experimental: mHealth with no home visits<br>Participants received the health facility delivery of CHoBI7, plus bi-weekly mHealth (voice and text) reminders for 12 months | Behavioral: CHoBI7 health facility program<br>* The CHoBI7 health facility program focuses on promoting handwashing with soap and water treatment to diarrhea patients and their household members during the one-week period after the patient is admitted to the health facility, when their household is at highest risk for diarrheal diseases. The CHoBI7 program includes: (1) a WASH pictorial module delivered by a health worker bedside to diarrhea patient and their household members in a health facility on handwashing with soap, water treatment, and safe water storage; and (2) a diarrhea prevention package containing chlorine tablets for water treatment, a soapy water bottle (water and detergent powder), a handwashing station, and a water vessel with a lid and tap for safe drinking water storage. Households are instructed to boil their water once their supply of chlorine tablets is completed.<br>Behavioral: CHoBI7 mHealth program<br>* The CHoBI7 mHealth (mobile health) program targets five key behaviors: (1) preparing soapy water using water and detergent powder; (2) handwashing with soap at food and stool related events; (3) treating household drinking water using chlorine tablets during the one week high risk period after the diarrhea patient in the household was admitted to the health facility; (4) safe drinking water storage in a water vessel with a lid and tap; and (5) heating of household drinking water until it reaches a rolling boil after the one week high risk period. Participant households receive bi-weekly voice and text messages from the CHoBI7 mHealth program over a 12-month period. These mobile messages are sent using the VIAMO platform (www.viamo.io).<br>|
| Experimental: mHealth with home visits<br>Participants received the health facility delivery of CHoBI7, plus two home visits and bi-weekly mHealth (voice and text) reminders for 12 months | Behavioral: CHoBI7 health facility program<br>* The CHoBI7 health facility program focuses on promoting handwashing with soap and water treatment to diarrhea patients and their household members during the one-week period after the patient is admitted to the health facility, when their household is at highest risk for diarrheal diseases.

These mobile messages are sent using the VIAMO platform (www.viamo.io).<br>Behavioral: CHoBI7 home visit program<br>* The CHoBI7 home visit program involves two, 30-minute home visits conducted during the week after the index diarrhea patient was recruited at the health facility. A health worker reinforces the content of the CHoBI7 health facility program in the participant's home.<br>|
