Cross-modality: delivery of health services through non-professionals.

The cross-modality (C-M) system of health care delivery was developed as one response to numerous societal requirements for better health care delivery. A pilot program is described which established C-M program in several institutions for the mentally retarded, using attendant staff as "primary deliverers of service." While the purpose of the program was to demonstrate the improved effectiveness of care, the additional cost-benefits of a C-M system appear significant. Dietetic literature supports the appropriateness of delivering certain dietetic services in selected environments through such a system.
