Table 2.
Types and timing of postoperative wound complications
| Variable | Value |
|---|---|
| Any postoperative wound complication, n (%) | 24 (27.9) |
| Primary wound complication type, n (%) | |
| Superficial incisional SSI | 10 (11.6) |
| Deep incisional SSI | 4 (4.7) |
| Organ/space SSI | 3 (3.5) |
| Wound dehiscence | 4 (4.7) |
| Seroma or hematoma requiring intervention | 2 (2.3) |
| Other wound-related complication | 1 (1.2) |
| Time to first complication diagnosis (days) | 7 [5–10] |
| Diagnosis on or before POD3, n (% of complications) | 4 (16.7) |
| Diagnosis after POD3, n (% of complications) | 20 (83.3) |
| Interval from POD3 sampling to diagnosis among complications diagnosed after POD3 (days) | 4 [2–7] |
| Complication requiring surgical intervention, n (% of complications) | 7 (29.2) |
| Thirty-day wound-related readmission, n (% of complications) | 5 (20.8) |
Values are presented as number (percentage) or median [interquartile range]. Complication categories represent the first and primary wound-related event documented for each patient and are mutually exclusive. Percentages for complication types were calculated using the total study sample as the denominator. Percentages for complication timing, surgical intervention, and readmission were calculated using patients with wound complications as the denominator.
