Information regarding NHS sickness absence statistics:
We perform the Monthly analysis of changes in sickness absence rates NHS workers in England. We use as a baseline the 2009-2019 average sickeness absence rate in each month of the year, in order to remove seasonality.
In this section we compute the deviation of sickness absence rate from the 2009-2019 average seasonal baseline. The chart in the left corresponds to the absolute deviation from the baseline (in percentage) while the chart on the right refers to the relative deviation from the baseline (in percentage).
In this section we compute the Z-score of the deviation of sickness absence rate from the 2009-2019 average seasonal baseline. This measure allows us to access the statistical significance of the deviation from trend that we observe in NHS absence sickness rates since the start of the pandemic. The normalisation factor (noise level) was taken as the standard deviation of deviations from trend during the 2009-2019 time period, prior to the pandemic.
We perform the yearly analysis of changes in sickness absence rates NHS workers in England. We use as a baseline the 2009-2019 average sickeness absence rate. The yearly analysis allows us to put into context the equivalent analysis we performed for the UK absence and lost worktime rates in the UK and the US.
