Table 2:
Adjusted odds of receiving a low-priority triage score for patients with acute myocardial infarction
| Characteristic | OR | 95% CI | p value |
|---|---|---|---|
| Chart record of depression | 1.26 | (1.05–1.51) | 0.01 |
| One cardiac risk factor* | 0.98 | (0.82–1.17) | 0.85 |
| Two or more cardiac risk factors | 1.00 | (0.87–1.16) | 0.97 |
| History of CAD | 1.04 | (0.91–1.20) | 0.56 |
| History of PCI or CABG | 0.84 | (0.69–1.03) | 0.09 |
| Age, per 10 years† | 1.09 | (1.04–1.14) | < 0.001 |
| Sex, male | 0.89 | (0.79–1.00) | 0.05 |
| Highest income | 1.01 | (0.84–1.20) | 0.95 |
| Chest pain in ED | 0.29 | (0.25–0.35) | < 0.001 |
| Chest pain within 72 hr | 0.68 | (0.53–0.86) | 0.001 |
| Short of breath | 0.90 | (0.80–1.02) | 0.10 |
| Cardiac arrest or shock | 0.01 | (0.00–0.07) | < 0.001 |
| Pulmonary edema | 0.45 | (0.34–0.60) | < 0.001 |
| Arrived by ambulance | 0.65 | (0.57–0.74) | < 0.001 |

| Weekend arrival | 0.99 | (0.86–1.13) | 0.86 |
| Teaching hospital | 1.18 | (0.70–1.99) | 0.54 |

| Very high ED AMI volume‡ | 0.28 | (0.19–0.41) | < 0.001 |
Note: AMI = acute myocardial infarction, CABG = coronary artery bypass graft, CAD = coronary artery disease, ED = emergency department, OR = odds ratio, PCI = percutaneous coronary intervention.
*
Diabetes mellitus, hypertension, smoker or dyslipidemia.
†
Values reflect odds of receiving a low-priority score per every 10-year increase in age.
‡
Volume was defined as follows: < 100 AMI patients/yr = low volume; 101–200 patients/yr = moderate; 201–300 patients/yr = high; ≥ 301 patients/yr = very high.
