Prior to April 2006, there was no obstructive sleep apnoea service across Lincolnshire, leaving a population of roughly 700,000 people with little provision for sleeping disorders. Due to increased access to resources more people are able to address their sleeping problems and enhance the quality of their lives. In 2008 the Sleeping Disorders Centre won the NHS East Midlands Healthcare Award for service transformation.
