A Longitudinal Study of Risk Factors Associated with the Formation of Pressure Ulcers in Nursing Homes

Abstract

Although low and high incidence homes share similar risk factors, such as ambulation and feeding activities of daily living, the main difference was that diabetes and fecal incontinence played a major role only in high risk homes, while male gender was an important discriminator only in low incidence homes. Yet, it is unclear if these factors explain the three-fold difference in the incidence rates for pressure ulcers in these facilities. Baseline or resident clinical characteristic differences of any one factor between the high and low incidence homes varied by no more than 5%. While we identified certain conditions which are associated with pressure ulcer formation, there may be unknown or unmeasured facility effects in addition to the characteristics of a given resident in a particular home.
