Pressure ulcer incidence and Braden subscales: Retrospective cohort analysis in general wards of a Portuguese hospital
Orientador(es)
Resumo(s)
Aim: To study the influence of Braden subscales scores (at the first pressure ulcer risk assessment) on
pressure ulcer incidence using a univariate and a multivariate time to event analysis.
Materials and methods: Retrospective cohort analysis of electronic health record database from adult
patients admitted without pressure ulcer(s) to medical and surgical wards of a Portuguese hospital
during 2012. The hazard ratio of developing a pressure ulcer during the length of inpatient stay was
calculated by univariate Cox regression for each variable of interest and by multivariate Cox regression
for the Braden subscales that were statistically significant.
Results: This study included a sample of 6552 participants. During the length of stay, 153 participants
developed (at least) one pressure ulcer, giving a pressure ulcer incidence of 2.3%. The univariate time to
event analysis showed that all Braden subscales, except “nutrition”, were associated with the development
of pressure ulcer. By multivariate analysis the scores for “mobility” and “activity” were independently
predictive of the development of pressure ulcer(s) for all participants.
Conclusion: (Im)“mobility” (the lack of ability to change and control body position) and (in)“activity” (the
limited degree of physical activity) were the major risk factors assessed by Braden Scale for pressure
ulcer development during the length of inpatient stay. Thus, the greatest efforts in managing pressure
ulcer risk should be on “mobility” and “activity”, independently of the total Braden Scale score.
