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.
