Unannounced inspections were carried out by the Care Quality Commission (CQC), England's health regulator.
Nearly half of the 145 hospitals and care homes inspected by the CQC did not meet required standards.
This comes after abuse was uncovered by BBC Panorama at the Winterbourne View home near Bristol.
The inspections focused on examining the general care and welfare of people who used the services as well as whether people were safe from abuse.
The CQC found 48% of the inspected premises did not meet required standards in terms of care, welfare and whether people were safe from abuse. The commission also said independently-run facilities were twice as likely to fail as those run by the NHS, it said.
The locations were made up of 68 NHS assessment, treatment and secure services, including two residential care homes. There were also 45 independent assessment, treatment and secure services and 32 residential care homes included in the report.
Independent services were twice as likely - 33% compliant - to fail to meet these standards as NHS providers, which were 68% compliant.
Of the 145 locations inspected, 69 failed to meet one or both standards and 35 failed on both standards.
There were minor concerns over premises that met both standards and only 35 fully met both standards with no concerns, the CQC said.
