'Significant improvement' to Southern Health NHS Foundation Trust
BBCAn NHS trust that failed to investigate hundreds of unexplained deaths has made "significant improvements".
A report commissioned in 2016 after the death of 18-year-old Connor Sparrowhawk found "serious failings" at Southern Health NHS Foundation Trust.
NHS Improvement said an independent review carried out last year had found "encouraging progress".
The trust was fined £2m after failing both Connor and Teresa Colvin, 45, who died in Hampshire in 2012.
Southern Health also pleaded guilty to failing to provide safe care and treatment after a patient fell from a roof in 2015.
The independent Mazars report found 272 of 722 unexplained deaths between 2011 and 2015 were not properly investigated.
Former chief executive Katrina Percy resigned in 2016, followed by its previous board of directors.
Anne Eden, executive regional managing director in the south east for NHS Improvement and NHS England, said: "The historic failings at the trust are well documented and it is right that the trust has been held to account for them.
"However, this is encouraging progress which represents improvements in services for local patients and should also be recognised.
"Southern Health continues to be subject to regulatory action from NHS Improvement to ensure they maintain momentum."
Nick Broughton took up the post of chief executive at the trust last year.
