The NHS Trust Development Authority is seeking more funding from the Department of Health to cope with an increased workload in the aftermath of the Francis inquiry, it has emerged.

The authority, which performance manages and assures providers as they seek to attain foundation trust status, said a lack of capacity was its greatest strategic risk and could compromise its ability to "maintain effective oversight and support of trusts".

The capacity gap is partly the result of an increased workload following the Francis, Berwick and Keogh reviews and the need to support the new Care Quality Commission inspection regime, the authority's most recent board papers state.

At the authority's board meeting last week, director of finance Bob Alexander said it faced two key strategic "inherently linked" risks. These were "capability and capacity of the [TDA] itself" and "the ability of some of our [trusts] to appropriately deliver in the challenging times that we have".

The authority has drawn up a business case for extra funds from the DH in the 2014-15 spending round to help it meet increased demand from trusts for support on clinical and quality issues following the Francis report. Its 2013-14 budget is £33.5m.

A spokesman for the authority said: ''We are in discussion with the department about the resources currently available... but while those discussions are ongoing it would be inappropriate to comment further."

Meanwhile, authority chief executive David Flory has said the organisation was interested in carving out a new role for itself coordinating the increasing number of interactions between trusts and other NHS organisations.

If different bodies' demands were not aligned, it was possible they may not support trusts' "best prospects", he said.

Mr Flory said: "No [arm's length organisation] is going to leave themselves open to criticism that they didn't know what was going on, or that they sat back and didn't act.  

“There's a risk that where it doesn't work well you're having six different conversations about six different disciplines to six different people. We think that part of our job is to bring alignment to all of that."
