Table 3.
Antimicrobials used before PJI diagnosis
| Antimicrobial used | Culture-negative (cases) (N = 89) | Culture-positive (control subjects) (N = 34) |
|---|---|---|
| Beta-lactam | 26 | 7 |
| Quinolone | 10 | 3 |
| Vancomycin | 2 | 0 |
| Combination therapy* | 35 | 14 |
| Other† | 16 | 10 |
Some patients received monotherapy and combination therapy at different point of time so the sum is higher than the number of patients who received antimicrobial therapy; *beta-lactam + quinolones, beta-lactam + vancomycin, quinolone + vancomycin, beta lactam + quinolone + vancomycin; †rifamycin, tetracycline, aminoglycoside, nitroimidazole, or penicillins; PJI = prosthetic joint infection.
