Compliance rates for in-patient mental health units across Mayo are varied, according to the 2018 Annual Report of the Mental Health Commission.
The Commission inspects in-patient mental health facilities that are registered with them at least once a year, and prepares a report on the findings of the inspection.
In Mayo, An Coillin in Castlebar was the highest rated adult centre in the county with an 86% approval rating - down slightly on the 89% rating it achieved last year.
The Adult Mental Health Unit in Mayo University Hospital was only 73% compliant - which was a drop of ten percent of the 2017 inspection.
Teach Aisling Unit, also in Castlebar, was just behind with 72 percent compliance with regulations. This, however, was a 13 percent improvement on 2017.
The lowest rated unit in Mayo was St. Anne’s unit in the Sacred Heart Hospital which scored 68 percent - significantly down from the 86 percent compliance rating it achieved in 2017.
All in-patient facilities in Ireland that provide care and treatment to people suffering from mental illness or disorder must be registered by the Commission.
Overall compliance rose from 76% in 2017 to 79 % last year.
