title: Heel pressure ulcers in orthopedic patients: a prospective study of incidence and risk factors in an acute care hospital.
abstract: Heel pressure ulcers (PU) are a major concern in orthopedic patients. A prospective 6-month study was conducted in an acute care hospital in Canada to determine the incidence of heel PU in an orthopedic population, evaluate the effect of patient and care variables on heel PU incidence, and describe the natural history/sequelae of Stage I heel PU. One hundred and fifty (150) patients (average age 70.6 years) admitted for elective orthopedic surgery or treatment of a fractured hip participated in the study. A direct heel skin assessment was performed following admission and before discharge. Patients with a Stage I ulcer were assessed or contacted 1 week following discharge. The incidence of heel PU in this population was 13.3% CI (range 8% to 19%). Incidence was 16% in the hip fracture and 13% in the elective surgery group. PU incidence in the hip fracture group was significantly lower (P = 0.016) for patients receiving heel pressure relief measures (pillows, rolled sheets). In the elective surgery group, PU incidence rates were higher for patients with respiratory disease, lower hemoglobin, low pulse rate, and altered mental status (P <0.05). When both patient groups were combined, only the presence or absence of respiratory disease significantly affected PU incidence. Length of stay was an average of 3 days longer in all groups with a heel PU but the difference was not statistically significant. One week following discharge, 13 of the 17 (76%) Stage I heel PU had resolved, one remained unchanged, and two were assessed as deep tissue injury (11%) and one as Stage II. These incidence rates are similar to those reported in other countries and confirm that efforts to reduce heel PU incidence rates are needed.
