Health workers going door-to-door with COVID-19 tests could help reach more vulnerable people, according to US scientists, who say the practice resulted in a substantial increase in the proportion of Latinx and elderly people getting a test. They also found the most effective way of targeting vulnerable people for health worker visits was to use artificial intelligence algorithms designed to select the neighbourhoods with the highest potential rate of positive COVID-19 cases while taking uncertainty into account. The second most effective method of targeting visits was basing them on health workers' local knowledge, followed by targeting areas with a high number of known cases. The study, which included 756 tested individuals, found the introduction of door-to-door testing was also linked to an increase in overall testing capacity of 60 per cent to 90 per cent, depending on the testing protocol, the authors say.
