Relationship Between Serum Albumin Levels And The Outcome Of Split-Thickness Skin Graft In Burn Injury Patients

Burn injury is still a global health problem due to its high incidence. Healing of burn wounds requires an optimal state of the body that is characterized by serum albumin level, especially in the category of patients that require skin graft to cover the wound caused by the deep burn. This study investigates the relationship between albumin levels and the outcome of split-thickness skin graft (STSG) and obtains a tolerance limit for albumin levels that can be successful in STSG. This was a prospective cohort study at our Plastic Surgery Center in Bandung, West Java, Indonesia from June 2019 to November 2020. Fortyseven burn injury patients who had undergone STSG qualified as the study subjects based on the criteria set. Of these patients, 85.11% were male and 68.08% were in the productive age. Preoperative albumin level has no significant correlation with graft outcome (P>0.05). Area Under the Curve (AUC) is 0.758; (95% CI: 0.605, 0.910). The optimal cut-off point for albumin levels is 2.175 (sensitivity of 0.78 and a specificity of 0.714). In our study, graft healing has no significant correlation with albumin levels. Further study is needed to assess the relationship between serum albumin levels (preoperative and postoperative) with outcome of the graft, and assess infection status.
