In addition the groups were compared on clinical and demographic variables comparing those exposed and those not exposed to the AAH service.Results The results indicated that the AAH group experienced reduced rates of readmission and lengths of stay post-exposure. Family composition, sex, seven Adverse Childhood Experience survey items, and nine Western Canada Waitlist Child Mental Health Priority Criteria Score items distinguished those exposed to AAH compared to those who were not. Thirteen of 19 independent variables indicated greater pathology in the AAH group with less likelihood of potential of danger to self.Conclusion The present results indicate a substantial benefit of the AAH service via reducing readmissions and lengths of stay. The quantitative measures warrant a careful qualitative examination of the AAH processes along with ongoing monitoring of the program’s effect.
