Screening for sarcopenia and frailty in patients with chronic ulcers: a cross-sectional study

Abstract

Background  Patients with venous ulcers report multiple comorbidities and are more likely to be physically inactive. Sarcopenia and frailty increase vulnerability to dependence and/or death.

Objectives  To investigate the occurrence of sarcopenia and frailty in patients with chronic venous ulcers.

Methods  Observational study with cross-sectional design. Nine patients (67.4 ± 8.42 years) with lower limb venous ulcers classified as CEAP 6 according to International Consensus on Chronic Venous Diseases criteria (open and active ulcer) were evaluated. Sarcopenia was assessed and classified by assessment of strength (manual dynamometry), gait speed (10-meter walk test), and muscle mass (calf circumference). Frailty screening was based on the Fried criteria, consisting of five components: unintentional weight loss; exhaustion; weakness; slow gait speed; and low physical activity.

Results  Frailty was more frequent (n=9; 100%) than sarcopenia (n=1; 11,1%). The most common Fried criterion was exhaustion (n=9; 100%), followed by low physical activity (n=8; 88,8%), muscle weakness (n=5; 55%), and unintentional weight loss. Finally, the least frequent criterion was slow walking speed (n=2; 22.2%). In the subject diagnosed with sarcopenia, both weakness and reduced muscle mass were observed (n=1; 11,1%).

Conclusions  Patients with chronic venous ulcers exhibit frailty or pre-frailty and the components that comprise the condition of frailty in this population are exhaustion, low physical activity, and muscle weakness. Sarcopenia was identified in a small proportion of the patients.
