System and cost research issues in treatments for people with autistic disorders.

Donahoe et al. (2000) wrote a big-picture essay. They listed what still needed to be studied about autism services.

They looked at cost, staff training, and how services fit together. No new data were collected.

The team said four gaps block families: high cost, long wait lists, weak staff training, and scattered programs.

They urged researchers to measure real-world dollars and to test ways to braid medical, school, and ABA care.

Vassos et al. (2023) picked up the same list and checked it 23 years later. Their scoping review of 31 studies shows we now describe families better, but cost and equity questions are still open.

Vivanti et al. (2025) explain why the gaps linger. Even when we have good tools, insurance rules and state policies keep them off the clinic floor.

Gasiewski et al. (2021) give a live example: BCBAs and OTs often duplicate work or clash because agencies lack a shared protocol, proving the 2000 "integration" call is still valid.

You can close part of the gap this week. Ask your director for a 30-minute meeting with OT, speech, and nursing. Map one client’s schedule together and spot double bookings or missed hand-offs. That single fix saves hours and shows funders you track system waste, the exact data W et al. said we still need.
