The regional medical charity the Yorkshire Medical Charitable Society has become part of the Royal Medical Benevolent Fund.
The society, which operates in the West Riding area, provides financial support and advice to doctors, retired or working, and their dependants. It will merge with immediate effect with benevolent fund, which is a national body that provides the same services but also helps medical students.
The society said support for the organisation had fallen in recent years and it was no longer financially viable.
The Yorkshire charity’s annual income in 2011 was £21,000, compared with the benevolent fund’s income of almost £1.7m. It was run by volunteers.
"In recent years the society had found it difficult to recruit members and had received no new applications for support," said Dr Andrew Cohen, president of the society.
"Over time it became clear that the costs of administering the charity were disproportionate to the income and to the number of beneficiaries. We are very pleased to be able to merge with the RMBF so that it can continue our work."
The national organisation will continue to support all the beneficiaries of the society, as well as its existing 350 beneficiaries.
Steve Crone, chief executive of the RMBF, said the regional organisation had made the right choice.
"Merging with the society makes sense because it ensures that we are not duplicating services and we can offer the best possible assistance to those that need us," he said.
