Abstract

Objective: The objective of this study was to evaluate the impact of the Cholera-Hospital-Based-Intervention-for-7-days (CHoBI7) handwashing with soap and water treatment mobile health (mHealth) program on diarrhoeal disease knowledge among diarrhoea patients and their household members in urban Dhaka, Bangladesh. Methods: A cluster-randomised controlled trial of the CHoBI7 mHealth program was conducted among diarrhoea patient households in Dhaka, Bangladesh. Patients were randomised to three arms: standard recommendation on oral rehydration solution use; health facility delivery of CHoBI7 plus mHealth (weekly voice and text messages) (no home visits); and health facility delivery of CHoBI7 plus two home visits and mHealth. An open-ended questionnaire was administered to 1468 participants 12 years of age or older on diarrhoeal disease transmission and prevention. These items were combined to form a diarrhoeal disease knowledge score measured at baseline and at a 1 week, 6 month and 12 month follow-up. Results: At baseline, when participants were asked to report three ways diarrhoeal diseases were spread 37% (546/1468) of participants reported by water, 13% (187/1468) by lack of handwashing and 4% (53/1468) by food not being covered properly. At baseline when asked to name three ways diarrhoeal diseases could be prevented, 35% (515/1468) of participants reported safe water, and 16% (228/1468) reported handwashing with soap. At the 12-month follow-up, the overall diarrhoeal disease knowledge score was significantly higher in the mHealth with no home visits arm (score coefficient: 0.69, 95% Confidence Interval: 0.36, 1.01, P < 0.0001) and the mHealth with two home visits arm (score coefficient: 1.18, 95% CI: 0.87, 1.49, P < 0.0001) compared with the standard recommendation arm. Conclusion: The CHoBI7 mHealth program significantly increased knowledge of diarrhoeal disease transmission and prevention among diarrhoea patients and their household members 12 months after in-person visits for program delivery were conducted.
