1. Sickness absence rates have been calculated by dividing the “FTE Number of Days Sick” by the “FTE Number of Days Available” as recorded in electronic staff records. These rates only include NHS staff working in hospital and community health services.
2. Sickness absence rates for public sector staff are published by ONS on an annual basis only. We have assumed that within a calendar year, sickness absence rates remain stagnant in for the purpose of creating a time series. The data are collected differently and so any direct comparison should be treated with caution.
