Since welcoming its first patient in September 2025, the program has completed diagnostic assessments for more than 70 youth and graduated 34 patients from treatment. The PHP serves patients through two specialized tracks: the Complex Neurobehavioral Unit (CNBU) for children with autism spectrum disorder (ASD), intellectual disabilities and high-risk behaviors, and the Integrated Care Program (ICP) for patients with a broader range of behavioral and mental health needs. 

A distinguishing feature of the program is its multidisciplinary approach, bringing together psychology, psychiatry, developmental and behavioral pediatrics, nursing, behavior analysis, social work, child and family therapy, education, nutrition, child life and creative therapies to deliver comprehensive care and diagnostic clarity. Program leaders note that many patients arrive without a definitive diagnosis or a clear treatment pathway, and the PHP's coordinated evaluation process helps families access evidence-based interventions and appropriate ongoing services. 

During its first year, the team identified a significant community need among children with ASD and co-occurring challenging behaviors. In response, the program adapted its clinical model, staff training and therapeutic programming to better support this population. Today, approximately 60% of ICP referrals involve patients with ASD, and 80% have a history of challenging or externalizing behaviors. 

The program has also met key operational goals, including maintaining targeted lengths of stay and achieving low staff turnover, helping ensure continuity of care for patients and families. Treatment typically lasts six to 12 weeks, with patients placed in the most appropriate program based on clinical acuity, safety considerations and readiness for group-based interventions.

Recognizing that successful treatment extends beyond discharge, the PHP provides ongoing support through outpatient care coordination, school collaboration and weekly parent skills and support groups. These services help families maintain progress and build connections to long-term community and health care resources. 

As the program enters its second year, Children’s Mercy plans to increase capacity while continuing to address gaps in care for children with complex developmental, behavioral and mental health needs. The team is already consulting with other institutions developing similar programs, reflecting the growing recognition of this model's impact.
