A hospital trust has increased its clinical research in the past year helping find better treatments for NHS patients.
North West London Hospitals NHS Trust increased the number of studies being carried out to 89 for the year with more than 2,500 patients recruited to take part.
In a league table published by the National Institute for Health Research Clinical Research Network, the research arm of the NHS, North West London is in the top ten of London trusts.
Director of research and development at the trust Joan Pitkin said: "We are very pleased with our performance to be in the top ten trusts for London and the highest district general hospital in the table.
"It reflects the time, and attention that has been given to research and the integral role that it has with clinical care and education.
"We are fortunate to receive strong support from the Trust and Executive Board and over the next 12 months we will be increasing our research portfolio with a number of interesting and innovative activities."
Clinical research carried out by hospitals across the country help provide evidence what works to help improve treatments for patients.
