St George’s Hospital is set to make a staggering £91m of savings in just two years.

A cost improvement programme by the Tooting-based St George’s Healthcare NHS Trust revealed targeted savings for this financial year (2014/15) of £45.2m and a further £45.8m next year.

The savings next year will include £10.2m from women and children’s services, £11.1m from medicine and cardiovascular and £10m from surgery, neuroscience and theatres.

A spokeswoman for the trust said the savings would not contribute to any job losses. She said the hospital expected further savings in the future but that this was the same for all of the NHS and they had made financial improvements of this scale in 2013/14.

The trust has a total income of £715m.

Following the revelation that health bosses must find £91m of savings in just two years, Sadiq Khan, MP for Tooting, asked St George’s for reassurances that it would not impact patient care.

He said: "Local residents will be very worried by the levels of cuts St George’s is required to make next year. Year on year our hospital has had to make big cuts and this is not sustainable. I have asked St George’s for reassurances that the cuts will not have an impact on patient care, but it is difficult to see how such a huge budget cut will not have adverse consequences.

"While the staff at St George’s Hospital do a fantastic job providing first class care for our community, the Government is placing too much strain on the NHS. We have had a massive top-down reorganisation on top of cuts to resources. This makes it increasingly difficult for doctors and nurses to do their jobs properly."

A spokeswoman for St George’s said the financial challenge faced by St George's is no different than that faced by all NHS providers and there remained a gap between the costs of rising demand and the funding they received. Consequently, efficiencies and cost savings are required to cope with this.

She said: "Achieving the financial challenge will be done in multiple ways. Many are specific to individual services, others are trust wide. There are cost savings we can make for example through better procurement of goods and services. We can also improve our finances by increasing the income we earn through providing more NHS services or from non NHS services such as rental from retailers on our site.

"We very carefully evaluate the impact on quality - which is patient safety, experience and outcomes - of every plan put forward. We reject any that will have an adverse impact for patients.

"There may come a point in the future that if NHS funding falls far enough behind the demands on it, that difficult choices may need to be made. We expect that such choices will be need to be made at national rather than local level."
