Predictive value of calf circumference measures obtained at ICU admission for 30-day survival time in critically ill patients

Objetivo

In light of the increasing need for simple yet informative predictors of ICU patient outcomes, we undertook an examination of the associations between calf circumference (CC) measures obtained at ICU admission and subsequent 30-day survival time.

Métodos

We conducted a retrospective single-center study. The study involved patients under MV from Jan-Jun 2023, admitted to the ICU due to acute respiratory failure, excluding post-surgery cases. CC measurements were taken within 48 hours of ICU admission. Subjects were categorized as having reduced CC if their measurements were < 34 cm for men and < 33 cm for women.

Resultados

25 patients were included in the study, with a mean age of 72.72 ± 14.33 years, of whom 64% were female. The mean CC, BMI and SOFA score were 31.08 ± 3.85 cm, 25.62 ± 4.96 kg/m2 and 7.36 ± 3.77, respectively. Patients with reduced CC did not differ from those with normal CC in terms of age, BMI and SOFA scores. The incidence of ICU death was 44%. A cox regression analysis indicated that calf circumference (CC) measured upon ICU entry was significantly and negatively predictive of the hazard for 30-day ICU mortality (B = - 1.339, SE = 0.619, p = 0.03).

Conclusão

Individuals admitted to the ICU with reduced CC were likely to have lower survival time when compared to those with normal CC. Our findings provide valuable insights into the potential utility of CC as an accessible and efficient indicator for mortality prediction in the critical care setting.
