The patients, aged between 72 and 92, sustained fatal injuries after falling while in the care of hospitals run by the trust. Four fell at the Princess Royal Hospital in Telford; the fifth died of injuries at the Royal Shrewsbury Hospital. The deaths took place between June 2011 and November 2012.
The HSE found a lack of close supervision of those in a confused mental state. Investigating officers found poor communication about the measures to stop frail patients falling had made the situation worse.
