What is the frequency of pressure injury in vascular patients undergoing major amputations?

Individuals with peripheral arterial disease who have undergone below or above knee amputations have limited mobility and may sit for long periods of time in a wheelchair, increasing their risk for pressure injury. The aim of this descriptive cross-sectional research study was to retrospectively review the charts of those patients with peripheral arterial disease undergoing lower limb amputations from 2016 to 2017 at a major academic medical center to determine the frequency of pressure injury. Hospital data were used to identify patients discharged from 2016 to 2017 with primary International Classification of Diseases (10th Revision) codes for below knee amputations/above knee amputations and pressure injury (ulcer). From 2016 to 2017, 46 patients were admitted to the inpatient vascular surgery service for a below or above knee amputation. Seventeen of those patients had documented pressure injuries at hospital discharge for a frequency of 37%. There were 11 males and 6 females with age range of 44 to 82 years with a mean age of 66 years. There was a total of 19 pressure injuries (2 patients had 2 pressure injuries). Ten of those 19 pressure injuries were present on admission to the hospital and 9 pressure injuries were hospital-acquired pressure injuries. Thirteen of the 19 pressure injuries (68%) were on the sacrum. Three of the pressure injuries (16%) were on the heel. Two (11%) were ischial pressure injuries with one knee (5%) pressure injury. Risk assessment is an essential part of vascular nursing practice that aims to identify individuals at risk for pressure injury with appropriate interventions to prevent their occurrence. Vascular nurses should be encouraged to educate patients/family members on the increased risk of pressure injuries in those undergoing amputation during hospitalization and after discharge to prevent them from occurring.
