Alternative developmental evaluation paradigm in centers for developmental disabilities.

The interdisciplinary evaluation has been a well-established process in centers for neurodevelopmental disabilities, but it is costly and may generate long waiting lists that can delay early diagnosis and treatment. An alternative evaluation paradigm was designed, using a specific screening approach, to improve use of staff time without compromising quality of care. An alternative model (AM) was designed, where a pre-designed selection process was used to sort new patients for either a comprehensive evaluation or a screening procedure, addressing medical, developmental and social issues with the additional use of developmental screening tools. A routine clinic (RC) comprehensive evaluation of each referral, was compared to the AM for waiting time, charges for patients, reimbursement to the center, and parents' and professional trainees' satisfaction. Results showed that waiting time for the screening procedure (10.3 weeks) was significantly reduced (RC 20.6 weeks). Charges for the screening procedure were significantly lower, but center revenues were not affected. Caregivers' satisfaction was maintained and trainees' satisfaction was high. The AM identified medical concerns sooner and encouraged collaboration with community resources. This study supports the use of an Alternative Developmental Evaluation paradigm for more effective use of interdisciplinary teams in centers for neurodevelopmental disabilities.
