This study investigated the effectiveness of the Way Back Support Service (WBSS) in reducing deliberate self-poisoning (DSP) and psychiatric hospital admissions. The results showed no significant differences between the intervention and control groups in terms of DSP re-admissions. However, the intervention group had a higher proportion of psychiatric admissions compared to one of the control groups. These findings suggest the need to modify the WBSS model of care to improve treatment engagement and retention, and to incorporate evidence-based treatments for reducing DSP repetition.
Introduction Active contact and follow-up interventions have been shown to be effective in reducing repetition of hospital-treated self-harm. The Way Back Support Service (WBSS) is a new service funded by the Australian government to provide three months of non-clinical after-care following a hospital-treated suicide attempt. The aim of this study was to investigate the effectiveness of WBSS in reducing deliberate self-poisoning (DSP) and psychiatric hospital admissions over a 12-month follow-up period for a population of DSP patients within the Hunter (Australia) region. Methods A non-randomized, historical controlled (two periods) trial design with intention-to-treat analyses. Outcome data were drawn from hospital records. Results There were a total of 2770 participants across study periods. There were no significant differences between cohorts for proportion with any, or number of, re-admissions for DSP in the follow-up period. For psychiatric admissions, the intervention cohort had a non-significantly greater proportion with any psychiatric admission and significantly more admissions compared to one of the control cohorts. Conclusion The WBSS model of care should be modified to strengthen treatment engagement and retention and to include established, clinical, evidence-based treatments shown to reduce DSP repetition. Any modified WBSS model should be subject to further evaluation.
