A number of serious regulatory breaches have been identified at an adult mental health unit in Co Mayo.
The 32-bed facility at Mayo University Hospital in Castlebar, was found to have four critical risk ratings, following an inspection by the Mental Health Commission (MHC).
A further four areas were deemed to constitute a "high risk" to the wellbeing of residents.
The findings are contained in a report published today by the MHC.
Inspections revealed that there were not enough therapeutic programmes in place for residents and that staff shortages were impacting on the provision of occupational therapy, psychology and social work services.
Radiators in the unit were found to pose a fire hazard and a cleaning schedule was not being implemented adequately.
The report says the premises was not clean, hygienic or free from offensive odours.
Following the inspection, officials from the commission requested an immediate meeting with HSE management to discuss their concerns.
The MHC says corrective actions have been outlined and a follow up inspection will judge how these are being implemented.
Breaches of rules and regulations at the Mental Health Unit in Castlebar have been identified in a series of inspections by the commission in recent years.
Monitoring has revealed concerns about consent to treatment, staffing levels and the standard of individual care plans.
