Pressure injury (PI) mainly occurs in bedridden older adults or those with physical limitations. Here, we aimed to determine the appropriate timing to conduct flap reconstruction in patients with PIs and identify factors affecting surgical outcomes. We retrospectively reviewed the data of all patients who received debridement or flap reconstruction surgery for PIs in our hospital from January 2016 to December 2021. The extracted data included patient demographics, surgical records, blood test results, vital signs, and flap outcomes. In total, 484 surgical procedures (364 debridements and 120 flaps) were performed on 216 patients. Serum albumin level of ≥2.5 g/dL remarkably increased the likelihood of complete wound healing (odds ratio [OR] = 4.12, P =.032) and reduced the risk of postoperative complications (OR = 0.26, P =.040). In contrast, advanced age (OR = 1.04, P =.045) and serum creatinine level ≥2 mg/dL (OR = 5.07, P =.016) increased the risk of postoperative complications. Thus, patients with a favourable nutrition status have a higher likelihood of achieving complete wound healing. By contrast, patients who are older and have serum creatinine ≥2 mg/dL and serum albumin <2.5 g/dL tend to develop more postoperative complications. Overall, thorough correction for patient inflammation, infection, anaemia, and malnutrition status can provide optimal flap surgery outcomes.
