Median | 25th–75th percentiles | Median | 25th–75th percentiles | P value | |
Patient days | 403 | 361–425 | 372 | 319–381 | 0.003 |
Central line days | 208 | 177–225 | 197 | 177–221 | 0.289 |

Central line utilization (%) (NHSN percentile) | 52 (25th–50th) | 45–53 | 57 (25th–50th) | 52–59 | 0.005 |
Ventilator utilization (%) (NHSN percentile) | 56 (75th–90th) | 54–59 | 67 (>90th) | 61–71 | 0.002 |
Number of VAPs | 3 | 2–5 | 2 | 1–3 | 0.009 |
Number of CR-BSIs | 0 | 0–0 | 0 | 0–0.8 | 0.317 |
VAP rate (NHSN percentile) | 14.8 (>90th) | 9.1–22.3 | 8.4 (75th–90th) | 3.8–2.6 | 0.008 |
CR-BSI rate (NHSN percentile) | 0 (0–10th) | 0–0 | 0 (0–10th) | 0–3.7 | 0.144 |
All values are reported per month.
Utilization and rates are calculated utilizing the NHSN equations:
Utilization = (number of device days/total patient days) × 100
Rate = (number of infections/number of device days) × 100
SIC-IR = Surgical Intensive Care-Infection Registry; IC = infection control; NHSN = National Healthcare Safety Network; VAP = ventilator-associated pneumonia; CR-BSI = catheter-related blood stream infection.
