What this trial studies

This observational study aims to understand the mechanisms behind diagnostic overshadowing, where symptoms in people with disabilities are misattributed to their disabilities rather than new or co-morbid conditions. Researchers will conduct a baseline audit of CPT code usage among patients aged 3-89 with and without specified disabilities, followed by manual chart reviews to analyze demographic and clinical factors. The goal is to develop educational programs and decision support tools for healthcare professionals to reduce diagnostic errors in this population.

Who should consider this trial

Good fit: Ideal candidates include patients aged 3-89 with specified disabilities who have received billed charges.

Not a fit: Patients under age 3, over age 89, or those with a secondary diagnosis of dementia may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic accuracy and better healthcare outcomes for individuals with disabilities.

How similar studies have performed: While the concept of diagnostic overshadowing is recognized, this specific approach to addressing it through systematic audits and education is relatively novel.
