Design outcomes

Primary

MeasureTime frame
School absences for COVID-19 measured using anonymised data contained in schools information management systems and relayed to Local Authority at weekly intervals

Secondary

MeasureTime frame
1. CO2, humidity, PM2.5 & PM10 levels in classrooms measured through air monitoring devices at 60 second intervals and relayed via API. 2. Power usage levels for HEPA devices measured through power consumption monitoring devices at 60 second intervals and relayed via API. 3. Primary and secondary Care level data will be collect via Connected Yorkshire data set at weekly intervals. The Connected Yorkshire programme links disparate routine electronic data in an anonymised database across primary care, secondary care, community care and social care for over 700,000 individuals at Bradford Teaching Hospitals NHS Foundation Trust.
