BACKGROUND Ireland has low provision rates of general and forensic beds compared with other western countries. In recent years there have been difficulties and delays in accessing forensic beds for prisoners with severe mental illness.

AIMS We aimed to determine clinical outcomes for male prisoners assessed as requiring psychiatric admission over an extended period, with time frames for admission and other outcomes. We aimed to determine whether admissions to forensic and non-forensic locations were risk-appropriate.

METHODS Participants included all male prisoners placed on psychiatric admission waiting lists in Ireland over five years 2015-2019. We described demographic, clinical and offending variables. We measured clinical outcomes including forensic admission, other admission and recovery with voluntary treatment in prison. We also measured times to clinical outcomes. Security requirements and clinical urgency were assessed using the DUNDRUM Toolkit scales 1 and 2.

RESULTS 541 male prisoners were placed on admission waiting lists and spent an aggregate of over 114 years on admission waiting lists during 2015-2019. Almost one quarter improved with voluntary treatment allowing removal from waiting lists, while over 75% did not. Admission was achieved for a majority of cases, albeit after lengthy delays for some. The most frequent outcome was diversion from remand to non-forensic inpatient settings. Non-forensic admissions arranged by the Prison Inreach and Court Liaison Service (PICLS) at Ireland's main remand prison at Cloverhill contributed 54% (179/332) of all admissions achieved and 76% (179/235) of all non-forensic admissions from prison waiting list. Median delay to admission was 59 days for forensic admissions and 69 days for admissions to non-forensic hospitals from sentenced settings, compared with 16.5 days for admissions to non-forensic hospitals from remand.

CONCLUSIONS Long delays for forensic admission during a five-year period of limited access to such beds were partly mitigated by transfers to non-forensic hospitals, mainly diversion of minor offenders from remand settings.
