Prognostic Factors in Patients with Pressure Sores in a University Hospital in Southern Brazil

Objective Despite advances in medical care, patients who are hospitalized or have spinal cord injuries often develop pressure sores. The objective of this study was to describe the epidemiological characteristics of pressure sores and evaluate factors associated with recurrence and cure. Methods In this historical cohort study, clinical and laboratory data were collected from medical records between 1997 and 2016. Results Sixty individuals with pressure ulcers were included; mean patient age was 38.1±16.5 (37.0) years, 83.3% were men, and 86.8% identified as white. Most patients (85.1%) had paraplegia, amputation, or trauma of the lower limbs with motor sequelae; the remainder (14.9%) were quadriplegic. Most (78.3%) underwent surgery, and the mean follow-up time was 1.8±2.5 years. The lesions were cured in 25 patients; they recurred in 25% of the patients, and recurrence was seen to be associated with the location of the lesions. Patients with recurrent lesions had more medical consultations and a longer treatment time. Individuals whose ulcers had healed had fewer lesions, higher body mass index (BMI), and a higher proportion of these patients underwent surgery. Conclusions BMI and location and number of lesions are prognostic factors. Level of Evidence IV, Case Series.
