Clinician vs. patient self-assessment (DASI results). This graph displays the discrepancy between clinician categorical assessments of functional capacity and patient self-assessments of functional capacity. Once again, patient self-assessments of functional capacity were determined from their scored responses to the Duke Activity Status Index (DASI), which generates calculated functional capacity in terms of metabolic equivalents of task (METs). At our Preoperative Evaluation Center, clinician functional capacity assessments are routinely documented in terms of the categorical groupings displayed on the x-axis. In this figure, the DASI patient self-assessments are plotted against clinician assessments of functional capacity. A lack of correlation is evident in this figure, particularly around the clinically significant value of four METs of physical work
