ROTHERHAM NHS Foundation Trust ended the year £13 million worse off than bosses had planned.
The trust, which runs Rotherham Hospital, ended the financial year with a budget deficit of £6.4 million.
It had aimed for a surplus of £6.6 million. This was based on receiving £6.5 million of sustainability and transformation funding from the Government.
But the trust was not entitled to receive this after the second quarter because it had not met targets.
Trust director of finance Simon Sheppard said: “It has been a challenging year not only in Rotherham but across the provider sector of the NHS and we were one of 105 trusts to report a deficit.
“Despite this, we have been able to invest £11.5 million across the organisation including the new Urgent and Emergency Care Centre, IT programmes, estate infrastructure and medical equipment.
“The priority for 2017/18 is to continue delivering good patient outcomes whilst managing this within our financial resources.”
