Change in Quality of Life After Moving a National Forensic Mental Health Service: A Dundrum Forensic Redevelopment Evaluation Study (D-FOREST)

Abstract

Aims

Forensic psychiatric services address the therapeutic needs of mentally disordered offenders in a secure setting. Clinical, ethical, and legal considerations underpinning treatment emphasize that the Quality of Life (QOL) of patients admitted to forensic hospitals should be optimised. This study aims to examine changes in the QOL in Ireland's National Forensic Mental Health Service (NFMHS) following its relocation from the historic 1850 site in Dundrum to a new campus in Portrane, Dublin.

Methods

This multisite prospective longitudinal study is part of the Dundrum Forensic Redevelopment Evaluation Study (D-FOREST). Repeated measures were taken for all inpatients in the service at regular 6 monthly intervals. The WHOQOL-BREF questionnaire was offered to all inpatients. An anonymised EssenCES questionnaire was used to measure atmosphere in wards. Data were obtained at 5 time points for each individual patient and ward. WHOQOL-BREF ratings were obtained across 5 time points with comparisons available for 4 time intervals, including immediately before and after relocation. For 101 subjects across 4 time intervals, 215 sets of data were obtained; 140 before and 65 after relocation with 10 community patients who did not move. Using Generalised Estimating Equations (GEE) to correct for multiple comparisons over time, the effect of relocation, with community patients as a control, was analysed by ward cluster and whether patients moved between wards. Observations were categorised according to security level – high dependency, medium secure, rehabilitation, or community – and trichotomised based on positive moves to less secure wards, negative moves to more secure wards, or no moves.

Results

Relocation of the NFMHS was associated with a significant increase in environmental QOL (Wald X² = 15.9, df = 1, p < 0.001), even when controlling for cluster location, positive and negative moves. When controlling for ward atmosphere, environmental QOL remained significantly increased after the move (Wald X² = 10.0, df = 1, p = 0.002). EssenCES scores were obtained within the hospital for 3 time points before relocation and 2 time points afterwards. No significant differences were found on the three subscales before and after the move. All three EssenCES subscales progressively improved with decreasing security level (Patient Cohesion: Wald X² = 958.3, df = 1, p < 0.001; Experiencing Safety: Wald X² = 152.9, df = 5, p < 0.001; Therapeutic Hold: Wald X² = 33.6, df = 3, p < 0.001).

Conclusion

The GEE model demonstrated that the move of the NFMHS improved self-reported environmental QOL. The cluster location made significant differences, as expected for a system of stratified therapeutic security, with a steady improvement in scores on all three atmosphere subscales.
