Table A1

Multiple logistic regression for risk factors associated with hospitalization for pandemic (H1N1) 2009 (nonhospitalized vs. hospitalized patients)*

Variable Coefficient (β) SE p value OR (95% CI)
Intercept 81.5 28.8
No. high-risk conditions† 1.24 0.48 0.01 3.44 (1.34–8.83)
Dyspnea 3.09 1.20 0.01 22.00 (2.12–228.80)
O2 saturation –0.86 0.30 0.004 0.42 (0.24–0.76)

*OR, odds ratio; CI, confidence interval; O2 Saturation, oxygen saturation. Variables included in regression analysis: age <5 y, number of high-risk Centers for Disease Control and Prevention conditions, history of prematurity, hemoglobinopathy, or chronic neurologic disease, presence of dyspnea, tachypnea, oxygen saturation, and acute renal failure. Chest radiograph infiltrate was not included in the model because only half of the study received a chest radiograph. This model was well-fitted with a Hosmer-Lemeshow statistic of 0.773.
†A high-risk condition as defined by the Centers for Disease Control and Prevention: age <5 y or >65 y; pregnancy; immunosuppression; chronic pulmonary, cardiovascular, hepatic, hematologic, neurologic, neuromuscular, or metabolic disorders; and long-term aspirin therapy in persons <18 y.
