Abstract

fetched live from OpenAlex

Abstract The COVID-19 pandemic has had a lasting impact on mental health, with lingering effects on the healthcare utilization of developmental disorders, such as autism spectrum disorder, attention-deficit/hyperactivity disorder, and intellectual disabilities. This study explores changes in developmental disorder healthcare utilization in the Alberta healthcare system before and after the pandemic. Results indicate an overall increase in the healthcare utilization of developmental disorders from 2018 to 2022. The ongoing impact of the pandemic on developmental disorders highlights the value of better surveillance, mental health support, and informed policy decisions to ensure individuals with developmental disorders and their families receive the necessary support and resources.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
