Abstract
- Background: Despite its correlation with skeletal muscle mass and its predictive value for adverse outcomes in clinical settings, calf circumference is a metric underexplored in intensive care. We aimed to determine whether adjusting low calf circumference for adiposity provides prognostic value superior to its unadjusted measurement for intensive care unit (ICU) mortality and other clinical outcomes in critically ill patients. Methods: In a secondary analysis of a cohort study across five ICUs, we assessed critically ill patients within 24 h of ICU admission. We adjusted calf circumference for body mass index (BMI) (25–29.9, 30–39.9, and ≥40) by subtracting 3, 7, or 12 cm from it, respectively. Values ≤34 cm for men and ≤33 cm for women identified low calf circumference. Results: We analyzed 325 patients. In the primary risk‐adjusted analysis, the ICU death risk was similar between the low and preserved calf circumference (BMI‐adjusted) groups (hazard ratio, 0.90; 95% CI, 0.47–1.73). Low calf circumference (unadjusted) increased the odds of ICU readmission 2.91 times (95% CI, 1.40–6.05). Every 1‐cm increase in calf circumference as a continuous variable reduced ICU readmission odds by 12%. Calf circumference showed no significant association with other clinical outcomes. Conclusion: BMI‐adjusted calf circumference did not exhibit independent associations with ICU and in‐hospital death, nor with ICU and in‐hospital length of stay, compared with its unadjusted measurement. However, low calf circumference (unadjusted and BMI‐adjusted) was independently associated with ICU readmission, mainly when analyzed as a continuous variable. [ABSTRACT FROM AUTHOR]
