Patients suffering from pressure ulcers remain to be a challenging task for nursing staff and doctors in the daily clinical management, putting-notably in the case of recurrences-additional strain on the constantly reduced resources in public healthcare. We aimed to assess the risk factors for the recurrence of pressure ulcers at our institution, a tertiary referral center. In this retrospective analysis of patients admitted to our division we identified risk factors for pressure ulcer recurrence. The hospital patient database search included all patients with a diagnosis of pressure ulcers of the torso and lower extremity. One hundred sixty-three patients were diagnosed with pressure ulcers and 55 patients with 63 pressure ulcers met our inclusion criteria. The 17 recurrences (27%) had an average follow-up of 728 days. Most presented with lesions of the ischial tuberosity (n=24). Recurrence was statistically associated with defect size (p=0.013, Cox regression analysis), and serum albumin levels (p=0.045, Spearman correlation), but no association was found for body mass index, bacterial profile, comorbidities, localization, previous surgery, or time-to-admission for reconstruction (all p>0.05). Supported by the recent literature we identified factors like defect size to be associated with pressure ulcer recurrence, but not with time-to admission for reconstruction or number of previous debridements. Whether laboratory values like serum albumin levels were the cause, the result or associated with pressure ulcer recurrence warrants further investigation.
