BACKGROUND: Communicating risk is part of primary prevention of coronary heart disease and stroke, collectively referred to as cardiovascular disease (CVD). In Australia, health organisations have promoted an absolute risk approach, thereby raising the question of suitable standardised formats for risk communication. METHODS: Sixteen formats of risk representation were prepared including statements, icons, graphical formats, alone or in combination, and with variable use of colours. All presented the same risk, i.e., the absolute risk for a 55 year old woman, 16% risk of CVD in five years. Preferences for a five or ten-year timeframe were explored. Australian GPs and consumers were recruited..View full abstract
The research was funded by the Australian Department of Health and Ageing. Officers of the Department attended the workshop in Stage (i) but had no input into the final selection of formats. Funding supported the development of the formats by Ms Sophie Rogers and the position of Dr Janet Spink for the collection and analysis of data.
