NHS Hull has been ranked as the most improved primary care trust in the country, according to a new report.
The Health Service Journal ranked NHS Hull first out of 144 primary care trusts (PCTs) for improvements in the NHS World Class Commissioning (WCC) assessment.
Last year the PCT was ranked 48th in the assessment taken from 148 PCTs.
World Class Commissioning is a government initiative aimed at improving the NHS.
The PCT said over the past year, NHS Hull's improvement in a total of the 11 skill areas assessed, plus key governance areas of finance, strategy and board, had been significant.
The results were taken from the 12 August edition of the Health Service Journal. Data was published for 144 of the country's 152 Primary Care Trusts.
PCTs are effectively in charge of commissioning local services, such as hospitals, GPs, mental health units and community clinics.
The coalition government recently announced it was to phase out primary care trusts and regional bodies known as strategic health authorities, with funding going directly to GPs.
NHS Hull Chief Executive, Christopher Long, said the result demonstrated "the real commitment and determination of staff".
He said: "World Class Commissioning is designed first and foremost to measure our skills as commissioners of services, ensuring that we have the knowledge, the local understanding and the capability to provide local people with the services they need.
"The better we are at using what patients and clinicians tell us to source high quality, cost-effective services, for example, the better this is for local people and the more likely we are to make in-roads into some of Hull's big public health issues such as heart disease and cancer."
