Random-intercept multilevel model predicting the probability of being prescribed a broad spectrum antibiotic c
| Exposure | Unadjusted Odds Ratio (95% CI) | Adjusted Odds Ratioa (95% CI) |
|---|---|---|
| Penicillin-nonsusceptible S. pneumoniae | ||
| All isolates | 1.13 (0.76, 1.49) | 1.12 (0.76, 1.48) |
| Blood isolates | 0.99 (0.59, 1.38) | 0.97 (0.58, 1.37) |
| Respiratory isolates | 0.97 (0.58, 1.37) | 1.10 (0.62, 1.58) |
| Penicillin-resistant S. pneumoniae | ||
| All isolatesb | 1.40 (1.08, 1.72) | 1.39 (1.08, 1.69) |
Abbreviations: CI, confidence interval
a
Adjusted for age, prior hospitalization for asthma, and chronic asthma medication
b
The outlier hospital did not report overall resistance and therefore is not included in this model
c
Odds ratios are given for every 10% change in penicillin-nonsusceptible or resistant pneumococcal isolate
