This statistical release presents information about sickness absence of staff in the NHS in Wales. New information is shown for the quarter ended 31 March 2021. Data for October to December 2020 has been revised.

In response to the current coronavirus (COVID-19) pandemic, additional and timelier management information is collected on sickness absence. It is not collected on the same basis as that published in this quarterly release, and therefore the figures will differ.

The management information suggests that a daily average of just over 2,100 (2.1%) staff were self-isolating over the quarter ended 31 March 2021, with the number decreasing each month from an average of around 2,500 in January to an average of just under 2,000 during March. Information on coronavirus and NHS activity and capacity is published in a weekly update.

A number of factors related to COVID-19 have impacted on the data this quarter:

  • shielding advice to the clinically extremely vulnerable was in place throughout the quarter
  • vaccinations were made available to healthcare workers (and others) from December 2020
  • the second peak in terms of confirmed cases was in early January 2021

Clinically extremely vulnerable staff on the shielding list, and therefore not in work due to that, are included in the self-isolating count. In these official statistics, NHS staff who are self-isolating or shielding are not counted as being off sick, and are therefore not included in these quarterly sickness absence statistics. The official statistics should continue to be considered the authoritative source of data on sickness absence in the NHS in Wales.

The data is sourced from the NHS Electronic Staff Record provided by Health Education and Improvement Wales (HEIW).

Data included in this release is published on StatsWales.

Trends in the sickness absence rate

Line chart showing the actual monthly sickness rate for the NHS in Wales, along with a 12 month moving average. These show monthly variations between 4.6% and 7.5% but the 12 month moving average only ranges from 5.1% to 6.0%. However, the 12 month moving average has increased since April 2020, in line with the COVID-19 pandemic.

Sickness absence on StatsWales

Sickness absence shows wide seasonal variation throughout the year with the rate lower in summer and higher in winter. To provide clearer information on long term changes to the rate of sickness absence a 12 month moving average is shown in Chart 1. The chart shows the 12 month moving average has remained at around 6.0% over the last year, despite the increases between March and April 2020 and again between September and December 2020. 

The chart also shows that the sickness absence rate for April 2020 is the highest recorded monthly rate (7.5%) followed by December 2020 (7.1%) – given the timing this is more than likely attributed to COVID-19. Those NHS staff self-isolating, which includes shielding staff, are not counted as being off sick and are therefore not included in these sickness absence rates.

Well-being of Future Generations Act

The Well-being of Future Generations Act 2015 is about improving the social, economic, environmental and cultural wellbeing of Wales. The Act puts in place seven wellbeing goals for Wales. These are for a more equal, prosperous, resilient, healthier and globally responsible Wales, with cohesive communities and a vibrant culture and thriving Welsh language. Under section (10)(1) of the Act, the Welsh Ministers must (a) publish indicators (“national indicators”) that must be applied for the purpose of measuring progress towards the achievement of the Well-being goals, and (b) lay a copy of the national indicators before Senedd Cymru. The 46 national indicators were laid in March 2016.

Information on the indicators, along with narratives for each of the wellbeing goals and associated technical information is available in the Well-being of Wales report.
