Cross-Cultural Adaptation and Reliability of the Home Falls and Accidents Screening Tool (HOME FAST) in Assessing Fall-Risk Home Hazards for Stroke Using Technologies over a Conventional Home Visit.

Only 10 pairs of videos and photographs were analysed for interrater reliability, so the agreement findings rest on a small number of homes. Cognitive debriefing was completed only with the Bahasa Melayu version, not comprehensively with Mandarin or Tamil. All comparison raters were occupational therapists, so the findings may not apply to other professions. The study was done in an urban area, and generalisability is limited by the sample size. Photographs and videos did not always capture the whole room, and obstructed pathways were often missed. The primary rater had more HOME FAST experience and did the assessment in person, which may explain why they identified more hazards than raters using images. The study reports translation and rating agreement, not fall outcomes.

Do not read the good agreement between image-based HOME FAST ratings and an in-person assessment as proof that this method prevents falls. The study tested translation and rating agreement in 10 analysed homes, and therapists reported that some photographs missed hazards such as slippery floors and lighting at night.
