Risk factors for PICU admission and need for HFNC determined by multivariate logistic regression analysis
| Characteristic | Need for PICU admission/HFNC |
||
|---|---|---|---|
| PICU admission | |||
| OR | 95% CI | P value | |
| Age < 6 mo | 3.03 | (1.72-5.26) | <.01 |
| Sex (male) | 1.15 | (0.73-1.81) | .53 |
| Malnutrition | 1.69 | (0.98-2.90) | .05 |
| Apnea | 3.52 | (1.95-6.46) | <.01 |
| RSV | 1.71 | (1.01-2.96) | .04 |
| Low absolute lymphocyte count | 1.03 | (1.01-1.06) | <.01 |
| Need for HFNC | |||
| Age < 6 mo | 2.17 | (1.58-3.03) | .01 |
| Malnutrition | 1.71 | (1.26-2.32) | .01 |
| Apnea | 2.25 | (1.57-3.24) | <.01 |
| RSV | 1.91 | (1.46-2.52) | <.01 |
| Atelectasis | 3.71 | (1.59-14.0) | <.01 |
For the first model (with PICU admission as the dependent variable), R2 = 0.30 and Akaike information criterion = 472.13; for the second model, (with need for HFNC as the dependent variable), R2 = 0.40 and Akaike information criterion = 1228.1. Both models were made by excluding those patients not tested for RSV (122 patients). Boldface indicates statistical significance.
