title: The Pressure Sore Status Tool a few thousand assessments later.
abstract: Although the Pressure Sore Status Tool (PSST) was developed using expert panelists and its reliability has been previously reported, the patterns that seem to be forming based on the first few thousand PSST assessments have not been reported yet. This paper will focus on analyses of a subset of PSST assessments that were collected as a by-product of testing a computerized assessment and decision support system. Changes in wound characteristics that appear to serve as "lead indicators" of healing, preliminary factor analysis data, and a correlation of total PSST scores with recorded stage will be discussed. Due to the sample size and variability within the data, it is premature to draw firm conclusions from the data. However, analyses of the first few thousand assessments and over 100 healed pressure ulcers show promise in confirming some prior speculations about wound healing. The data also appear to suggest the possibility of surprises that are not necessarily part of current understanding of wound healing in pressure ulcers.
