A census has revealed that anti-psychotic medication is given to more than two thirds of inpatients with learning disabilities in specialist units.
The findings also showed that over half (56.6%) of the patients had experienced an "incident" during the three months preceding the census date such as self-harm, an accident, physical assault on the patient, hands-on restraint or seclusion.
The analysis of the 2013 Learning Disability Census was commissioned in response to events at Winterbourne View Hospital and have been published by the Health and Social Care Information Centre (HSCIC).
Its results are based on survey responses received from 104 (58 NHS and 46 private) provider organisations in England on behalf of 3,250 service users in September last year.
The Care Quality Commission have said they were surprised and disappointed to learn that hospital and care homes were 'failing vulnerable adults'.
CQC chairman Dame Jo Williams said: "Our concern was that people who work in this sector need to understand when and how restraint can be appropriately used."
- Independent services were twice as likely (33% compliant) to fail to meet these standards as NHS providers (68% compliant).
- Some assessment and treatment services admit patients to care for disproportionately long periods of time and discharge arrangements take too long to arrange.
- Of the 145 locations inspected, 69 failed to meet one or both standards and 35 failed on both standards.
- There were minor concerns over the locations that met both standards and only 35 fully met both standards with no concerns
- The locations were made up of 68 NHS assessment, treatment and secure services, including two residential care homes, while 45 were independent assessment, treatment and secure services.
- There were also 32 residential care homes included in the report.
Nearly half of Britain's hospitals and care homes are failing vulnerable adults, the Care Quality Commission (CQC) have said.
Nearly half of the 145 hospitals and care homes inspected nationwide did not meet required standards in terms of care.
The unannounced inspections were carried out in the wake of abuse uncovered by the BBC's Panorama programme at Winterbourne View hospital near Bristol.
The undercover footage showed staff at the hospital appearing to taunt and abuse the vulnerable adults in their care.
But there was no evidence in this report that pointed to abuse on the scale uncovered at Winterbourne View hospital, the report said.
People with learning disabilities have a one in two chance of receiving substandard care, a report by the care services watchdog revealed today.
Nearly half of the 145 hospitals and care homes inspected nationwide by the Care Quality Commission (CQC) did not meet required standards in terms of care, welfare and whether people were safe from abuse, the report showed.
