Table 3. Risk-Adjusted Odds Ratios of 90-Day Mortality at Affiliated Hospitals Compared With Top-Ranked Cancer Hospitals.
| Surgical Procedure | Risk-Adjusted Odds Ratio (95% CI)a | P Value |
|---|---|---|
| All procedures | 1.40 (1.23-1.59) | <.001 |
| Lobectomy | 1.34 (1.03-1.74) | .03 |
| Colectomy | 1.32 (1.12-1.56) | .001 |
| Gastrectomy | 2.04 (1.41-2.95) | <.001 |
| Esophagectomy | 1.48 (0.98-2.22) | .06 |
| Pancreaticoduodenectomy | 1.59 (1.12-2.24) | .009 |
a
Hierarchical logistic regression for 90-day mortality adjusted for patient-level covariates (age, sex, race/ethnicity, year of surgery, Elixhauser comorbidity score, and admission type) and includes a hospital-specific random effect to account for clustering of patients within hospitals. For the model including all procedures, the model was also adjusted for type of procedure. For colectomy and gastrectomy, models also adjusted for partial or total resection. The odds ratio depicts mortality risk at affiliated hospitals with top-ranked cancer hospitals serving as the reference.
