Delays in discharge and long stays in an inpatient setting continue to be thorns in the flesh of forensic intellectual disability services. The issues of fragmented transition planning, complexity of risk management, and insufficient community coordination often lead to the unreasonable length of stay and discharge inefficiency. This research paper suggests and experiments a structured Discharge Pathway Protocol (DPP) model of care to combine admission-based discharge planning, dynamic risk stratification, a milestone-based rehabilitation objective and a multi-agency transition governance. The outcome of a 12 months service evaluation was compared to that before and after applying the DPP to a low security forensic inpatient unit dealing with intellectual disability within an inpatient unit (n=40 discharges). Findings at the post-implementation showed a decrease in median length of stay (26.5 to 19.0 months), inpatient incident rate (4.2 to 2.9 incidents per 30 days), and mean placement delay (118 to 74 days). The proportion of milestone achievement before discharge rose to 84% and 12-month readmission fell to 15%. The analysis of % change showed that the direction of change was positive and steady on the key service indicators. The evidence indicates that planned, progressive discharge governance could be effective in promoting the efficiency of transitions and rehabilitation congruency within forensic intellectual disability facilities. The offered DPP model provides an adaptable model on how to integrate discharge planning at point of admission and reinforce multi-agency coordination. Additional multi-site confirmation and longitudinal analysis is justified in order to determine reproducibility and long-term effect.
