Predictors of Complications and Recurrence After Pressure Injury Reconstruction in Spinal Cord Injury: A Systematic...

Spinal cord injury (SCI) predisposes patients to pressure injuries (PIs) often requiring surgery. Multiple factors influence postoperative complications and recurrence, though their associations remain unclear. We performed a PRISMA-guided systematic review and meta-analysis to assess predictors of acute postoperative complications and PI recurrence in SCI patients undergoing surgery. PubMed, Scopus and Embase were searched. Studies with ≥ 15 participants were eligible; 24 (n = 2566 subjects) were included, with 15 (n = 1976 subjects) quantitatively synthesized. Risk of bias was assessed with the Newcastle-Ottawa Scale. A random-effects model meta-analysis was performed, and odds ratios (OR) were pooled when > 2 studies were available; otherwise, findings were narratively synthesized. Moderate-quality evidence showed prior flap reconstruction increased complication risk (aOR = 4.98). Low-quality evidence linked diabetes (OR = 1.39) and smoking (OR = 1.35) with complications. Higher recurrence risk was associated with prior flap reconstruction (OR = 1.80) and thoracic injury (OR = 2.21), while cervical injury was protective (OR = 0.37). Prior flap reconstruction resulted as the strongest predictor of complications and significantly increased the odds of recurrence. These findings underscore the importance of a multidisciplinary approach for preventing the first occurrence of flap reconstruction and subsequent procedures.
