Abstract

fetched live from OpenAlex

Multiple studies have reported decreased emergency department (ED) patient volumes during the coronavirus disease (COVID-19) pandemic, [1][2][3][4][5][6] including areas most aff ected by the virus.[7] Most existing studies have investigated general trends in ED presentations and have not examined the impact of COVID-19 on different types of EDs, specific ED patient groups, or illness presentations.This study is a retrospective observational study of changes in ED volumes during the first wave of the COVID-19 pandemic in Nova Scotia (NS).NS is an Atlantic Province in Canada with a population of 979,351.[8] The Government of NS declared a state of emergency on March 22, 2020, to help contain the spread of COVID-19.By June 22, 2020, the end of the first wave of COVID-19 in the province, there had been a total of 1,061 cases of COVID-19 and 65 deaths from the disease.[9]

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.
