The Mental Health Commission says issues remain around the condition of some mental health service buildings, individual care planning, risk management and staffing.
The Mental Health Commission has warned that Health Service Executive mental health services risk being removed from the register of approved centres if they do not improve compliance.
The commission has published its annual report for 2022, which includes a report on the inspection of 66 approved in-patient centres.
The report found that there had been an "overall and continued improvement and compliance across all services" when comparing pre and post-Covid-19 figures.
Just under half of the approved centres achieved 90% compliance or higher and no service had less than 71%.
However, four key areas around premises, individual care planning, risk management and staffing, had compliance levels of less than 70%.
The Mental Health Commission says there's been improvement in mental health services in Ireland, but issues remain around the condition of some mental health service buildings, individual care planning, risk management and staffing.
Commission Chief Executive John Farrelly says poorly performing centres face not being re-registered:
