To date, most of the evidence supporting this model has originated from outside the United Kingdom. A central aim of the AOT was to reduce the need for in‐patient treatment. We aimed to assess the impact of the AOT model on hospital admissions for people with psychosis in England. Interrupted time series analysis was used in this study to evaluate the impact of the policy change. Following the introduction of the AOT model, a statistically significant reduction in hospital admissions for psychosis was found. In addition, we observed a repeated, annual summer peak in admissions. This study adds to the international evidence which supports the effectiveness of the AOT model in reducing hospital admissions for people with severe mental health problems. We offer five suggested implications for mental health nurses and clients based on our findings.</p> </sec> </abstract>
