Tens of thousands of sick notes were given to patients in Brighton and Hove last year.

Since 2012, GPs have been able to give patients electronic 'fit notes', which say whether the patient is too sick to return to work, or give other recommendations, such as a phased return to work.

NHS Digital data shows 43,901 of these notes were given to patients in the former NHS Brighton and Hove CCG area in the year to June – equivalent to 18,838 for every 100,000 registered working-aged patients, though this was among the lowest rates in country.

These figures cover the number of individual notes issued, and patients may have received multiple notes over the course of the year.

Across England, the number of fit notes rose to 10.4 million in the year to June, up 8.6 per cent from 9.5 million in the year to June 2019.

There has also been a significant national increase in fit notes given for long durations – 132,000 fit notes were issued for leave of 20 weeks or longer in the year to June, up 42 per cent from 93,000 three years prior.

It has been suggested that long Covid – a range of coronavirus-related symptoms which remain after the initial period of infection has passed – could be contributing to the increase in workers being signed off for longer periods, alongside lengthy waiting lists for NHS treatment since the start of the pandemic.

In the year to June, 4.3 million notes – or 42 per cent of all fit notes – were for leave of a month or longer, up from 3.3 million – 34 per cent – in 2018-19.

Data from the Office for National Statistics shows the number of people off work due to long-term sickness in the UK is at all-time high, with 2.49 million people now 'economically inactive' due to ill health.

The Health Foundation, a charity which carries out research on healthcare, said that this rise in sickness duration was "incredibly worrying" and could have disastrous consequences if people are forced to leave work altogether.

Dave Finch, assistant director at the charity, said that long-term sickness is especially tough on those trying to make ends meet during the cost-of-living crisis.

Mr Finch said businesses need to be open to mitigating circumstances for their employees, and that the Government should consider greater financial support for workers while they are off sick.

A spokesman for the Department of Health and Social Care said they have published updated guidance to employers on how to support employees that are managing a health condition.

They added: “For anyone with a disability or long-term health condition, including long Covid, there is a strong financial safety net, including Statutory Sick Pay, Employment and Support Allowance and Universal Credit."

In July, clinical commissioning groups were abolished and replaced with integrated care boards across England.
