09 April 2021 The Suffolk CoronaWatch project has allowed the council to turn data into decisions and evidence into actionable insight, write the head of population insight at Public Health Suffolk, Suffolk CC, and the assistant director, knowledge & intelligence, at Suffolk CC. For a long time, local authority public health teams have grappled with incomplete, out of date, and restricted public health data. For many datasets, such as smoking, cancer diagnostics, obesity statistics and hospital admissions, these issues remain. However, Covid-19 has presented both challenges and opportunities in the way we work with and utilise local public health datasets. Like many other local authorities, Suffolk has needed to adapt and innovate to analyse Covid-19 data, and the Suffolk CoronaWatch tools have enabled us to turn data into decisions, and evidence into actionable insight.
