Introduction: The Falls in Care Home (FinCH) study is a large (*87 care homes, 1698 resident across 10 UK sites) randomised controlled trial evaluating whether a systematic falls programmes called the Guide To Action Tool (GtACH) reduces falls for care home residents. Large complex rehabilitation trials, such as FinCH, are at risk of contamination bias which can occur when participants in the control group are inadvertently exposed to the intervention. Such trials are also at risk of the intervention being adopted into clinical practice before effectiveness has been established.
