A common experience working in the human services field is fragmented systems of care. While the human service delivery system in the United States as a whole is robust with a plethora of providers, advocacy agencies in each sector from drug and alcohol, mental health, vocational rehabilitation, employment, leadership training right through to in-home care and non-medical transportation. However, the system as a whole is deeply siloed. There are many reasons for this fragmentation from reimbursement and funding structures and policy perspectives to organizational structures and theoretical foundations that underpin service provision mindsets. An area where this fragmentation is extremely pronounced is between the mental/behavioral health system and the service delivery system in place to support people who experience intellectual and developmental distinctions. There is a significant gap between two systems that should be tightly integrated.
