| 30-d mortality, % (95% CI) | 2.9% (1.0, 6.7) | 4.3 (3.4, 5.3) | .54 |
Note. CI = confidence interval; ICU = intensive care unit; OR = odds ratio. CURB-65 is a clinical prediction rule used to estimate 30-day mortality for patients with community-acquired pneumonia on the basis of confusion, uremia (blood urea nitrogen ≥ 20 mg/dL), respiratory rate (> 30 breaths/minute), systolic blood pressure (< 90 mm Hg) or diastolic blood pressure (< 60 mm Hg), and age (≥ 65 years).
a
Adjusted for illness severity using eCURB.
b
Of hospitalized patients.
c
Of patients initially managed as outpatients.
