Changes in frailty scores after surgery
Figure 4 shows the mean changes in frailty scores for frail,
pre-frail and robust patients with both scales. Negative values indicate
that patients are less frail 6 months after surgery and positive values
indicate a postoperative deterioration of the frailty status.
The most negative change in frailty scores occurred in the group of
frail patients. Pre-frail patients showed also negative changes in
frailty scores as well, although these changes were less marked that in
frail patients. Conversely, robust patients experimented a slightly
positive change. This linear trend in the changes of frailty scores that
can be graphically appreciated, was also statistically significative
(p<0.01) in a linear regression model.
