The time patients and caregivers spend at a health facility for severe diarrhea presents the opportunity to deliver water, sanitation, and hygiene (WASH) interventions. We recently developed Cholera-Hospital-Based Intervention for 7 days (CHoBI7), a 1-week hospital-based handwashing with soap and water treatment intervention, for household members of cholera patients. To investigate if this intervention could lead to sustained WASH practices, we conducted a follow-up evaluation of 196 intervention household members and 205 control household members enrolled in a randomized controlled trial of the CHoBI7 intervention 6 to 12 months post-intervention. Compared with the control arm, the intervention arm had four times higher odds of household members' handwashing with soap at a key time during 5-hour structured observation (odds ratio [OR]: 4.71, 95% confidence interval [CI]: 2.61, 8.49) (18% versus 50%) and a 41% reduction in households in the World Health Organization very high-risk category for stored drinking water (OR: 0.38, 95% CI: 0.15, 0.96) (58% versus 34%) 6 to 12 months post-intervention. Furthemore, 71% of observed handwashing with soap events in the intervention arm involved the preparation and use of soapy water, which was promoted during the intervention, compared to 9% of control households. These findings demonstrate that the hospital-based CHoBI7 intervention can lead to significant increases in handwashing with soap practices and improved stored drinking water quality 6 to 12 months post-intervention.<\/jats:p>","DOI":"10.4269\/ajtmh.15-0502","type":"journal-article","created":{"date-parts":[[2016,1,5]],"date-time":"2016-01-05T02:29:47Z","timestamp":1451960987000},"page":"428-436","source":"Crossref","is-referenced-by-count":29,"title":["Sustained Uptake of a Hospital-Based Handwashing with Soap and Water Treatment Intervention (Cholera-Hospital-Based Intervention for 7 Days [CHoBI7]): A Randomized Controlled Trial"],"prefix":"10.4269","volume":"94","author":[{"given":"Christine Marie","family":"George","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Danielle S.","family":"Jung","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.
