Norfolk and Norwich University Hospital, along with artificial intelligence firm Rainbird, have developed a tool to assess the risk of frontline workers being exposed to Covid-19. The tool uses intelligent automation, a combination of robotic process automation (RPA) and artificial intelligence (AI), to evaluate a range of factors including age, health history, cultural/religious beliefs, disability and pregnancy. It also factors in the impact of Covid-19 on Black Asian Minority Ethnic (BAME) groups. According to a report by Public Health England, a disproportionate number of BAME people have died from Covid-19, with people of Chinese, Indian, Pakistani, other Asian, Caribbean and other Black ethnicity having between 10 and 50% higher risk of death when compared to White British. As a result, Public Health England has called for "culturally competent" risk assessment tools for key workers.
