Table 1.

Baseline characteristics with averages and 95% confidence intervals (CI’s) are shown. The proportion of each McPherson stage is shown. Infection type is broken into acute postoperative (Stage I) and late post-operative (Stage II/III). Host grade is given by A - “uncompromised,” B – “compromised,” and C – “significantly compromised.” Outcomes of successful treatment, surgeries for infection, and days in hospital for infection are shown with proportions or averages and 95% CI’s.

Age at first infection 60.6 (58.3, 62.9)
Caucasian 102 / 149 (68.5%)
Female gender 77 / 149 (51.7%)
Previous infection treatment at outside hospital 36 / 149 (24.2%)

B 36 / 149 (24.2%)
C 25 / 149 (16.8%)
Outcomes Average (lower 95% CI, upper 95% CI) or proportion
Successful treatment rate 128 / 149 (85.9%)
