Abstract

fetched live from OpenAlex

IMPORTANCE: Pediatric appendicitis outcomes have been shown to be influenced by several patient-, surgeon-, and hospital-level factors. However, to our knowledge, no prior studies have investigated the effect of health care systems on outcomes. OBJECTIVE: To test the hypothesis that the outcomes of children with appendicitis are better in the Canadian single-payer universal health care system than in the US multipayer system. DESIGN, SETTING, AND PARTICIPANTS: A population-based comparison of outcomes using the US Kids' Inpatient Database and the Canadian Discharge Abstract Database was performed. Subanalyses by age group, US insurance status, and severity of appendicitis (nonperforated or perforated) were also performed. We included patients younger than 18 years coded for nonincidental, urgent appendectomy in the 2006 and 2009 Kids' Inpatient Database (78,625) and 2004 to 2010 Discharge Abstract Database (41,492). MAIN OUTCOMES AND MEASURES: Perforation rate, normal appendix rate, and length of hospital stay. RESULTS: Canadian patients had higher rates of normal appendix (6.3% vs 4.3%; P < .001) and perforated appendicitis (27.3% vs 26.7%; P = .04). The Canadian perforation rate fell in the middle between privately insured (24.1%) and publicly insured or noninsured US patients (30.4% and 31.2%, respectively). The Canadian perforation rate was lower in the 0- to 5-year age group (47.7% vs 52.3%; P < .001) and higher in the 12- to 17-year age group (24.7% vs 21.8%; P < .001) vs US patients. In Canada, hospital stay was longer after simple appendicitis (mean [SD], 2.0 [1.2] vs 1.7 [1.2] days; P < .001) and shorter after perforated appendicitis (mean [SD], 4.8 [3.6] vs 5.3 [3.7] days; P < .001). CONCLUSIONS AND RELEVANCE: Differences in outcomes of pediatric appendicitis between the United States and Canada are influenced by age and US insurance status. These differences are relevant to health policy decisions in both nations.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
