West London Mental Health NHS Trust is to be scrutinised by the Healthcare Commission to examine whether it takes appropriate action to address causes of incidents and prevent them reoccurring.
Inspectors from the commission made unannounced visits to the trust’s sites on February 13 and concluded that internal procedures must be investigated.
Areas of focus will be patient safety procedures, how the trust investigates ‘near misses’ and how it learns from incidents.
The number and type of incidents in the specified time period and corporate governance are also within the investigation's terms of reference.
The trust employs 3,800 staff across 32 sites and provides care for 18,000 patients of all ages across the London boroughs of Ealing, Hounslow, Hammersmith and Fulham.
Nigel Ellis, the commission’s head of investigations, said: ‘We are not saying the services provided by the trust are unsafe. If we believed they were unsafe we would take immediate action. But we have a duty to patients to be certain that all necessary systems are in place.’
