Outcomes after adequate and inadequate empiric antimicrobial therapy in patients with bloodstream infection using propensity score matching.
| Outcome Variable | Adequate Empiric Regimen n (%) |
Inadequate Empiric Regimen n (%) |
Difference n (%) |
OR # | 95%CI | p ^ |
|---|---|---|---|---|---|---|
| 14-day mortality | 17/167 (10.18) | 16/167 (9.58) | 1 (0.60) | 0.77 | 0.43–1.85 | 0.45 |
| 30-day mortality | 25/167 (14.97) | 21/167 (12.57) | 4 (2.40) | 0.78 | 0.42–1.47 | 0.45 |
| Length of hospital stay in days *, median (IQR) | 10.7 (4.6–18.2) | 10.5 (4.3–20.3) | – | – | – | 0.89 |
OR: odds ratio; 95%CI: 95% confidence interval; *: days counted after day of withdrawal of the positive blood culture; #: ORs were adjusted for type of pathogen (high-risk pathogen: Enterobacterales, S. aureus, Streptococcus spp. or Pseudomonas spp.); ^: OR and p-values were calculated by using logistic regression analyses. For comparison of the length of hospital stay a Wilcoxon rank sum test was applied.
