Below is a breakdown of acute and combined trusts by the share of staff saying they had witnessed potentially harmful errors, near misses or incidents in the last month, in the 2018 NHS staff survey.

The survey was carried out between September and December 2018 and results were published last week. All 230 trusts in England took part.

The proportion of NHS staff witnessing an error, near miss or other safety incident has reached its highest level for five years, the results revealed.

More than a quarter (27.8 per cent) of workers said they had seen an error that could have harmed patients or service users in the previous month.

This is three percentage points higher than in 2017 and the highest proportion for five years, half a percentage point higher than in 2014.

Weston Area Health Trust reported a high number of staff reporting an error. A spokeswoman said: “We encourage our staff to report potential harmful errors so that we can take learning from them.

“We want to create a culture where staff feel they can raise safety concerns so we can identify themes, raise awareness and take any preventative measures required.”

The trust with the highest percentage of staff witnessing errors was King’s College Hospital Foundation Trust. HSJ has approached King’s for comment.
