Ethnicity tool set for CVD screening
The National Screening Committee is to consider a new tool that adjusts risk of cardiovascular disease by ethnicity for use in its planned CVD screening programme.
Called Ethrisk, the tool is also being considered by the NICE team reviewing the Framingham risk charts as reported by Pulse in February. The tool, which substantially improves on 'crude' current corrections for ethnicity, is detailed in a study published online by Heart.
Using two community surveys of 3,778 men and 4,544 women, a team led by NICE risk assessment expert Dr Peter Brindle calculated the CHD and CVD risks in seven different ethnic groups (see box, right).
The 10-year risk of CVD for a 50-year-old, non-smoking man varied from just 5.4 per cent in Chinese patients to 12.8 per cent in Bangladeshis.
Dr Brindle, head of research strategy at Bristol PCT and a GP in Bristol, told Pulse: 'NICE will be looking at it as well as other ways of adjusting for ethnicity. It is an advance it takes into account sex whereas JBS assumes the risk for men and women is the same, in south Asians at least.'
Dr Paramjit Gill, fellow researcher on the study and a GP in Birmingham, said: 'The tool might come into screening later. This is the first that can take into account black and minority ethnic groups, including the Irish.'
