[BDSP. Notice produite par INIST aF2sNR0x. Diffusion soumise à autorisation]. This study characterized risk factors for household evacuation failure. A random digit dial telephone survey was conducted of 397 households in Yuba County, California, in July 1997,6 months after residents had been under evacuation notice due to flooding. Case households failed to evacuate, whereas control households evacuated. The cumulative incidence of household evacuation failure was 19.4%. Fewer households with children (25.8%) failed to evacuate than households without children (45.9%, p<0.01). More households with pets (20.9%) than households without pets failed to evacuate (16.3%, p=0.11). With multivariate logistic regression, the risk of household evacuation failure was lower in households with children (odds ratio=0.4,95% confidence interval : 0.2,0.8) compared with households without children. The risk of household evacuation failure increased in pet-owning households without children (odds ratio=1.3,95% confidence interval : 1.1,1.5) compared with pet-owning households with children ; the more pets a household owned, the higher the risk of household evacuation failure was. Impediments to pet evacuation, including owning multiple pets, owning outdoor dogs, or not having a cat carrier, explained why many households that owned pets failed to evacuate. Predisaster planning should place a high priority on facilitating pet evacuation through predisaster education of pet owners and emergency management personnel.
