RESUMO

BACKGROUND: Patients with critical COVID-19 often require invasive mechanical ventilation (IMV) and admission to the intensive care unit (ICU), resulting in a higher incidence of ICU-acquired weakness (ICU-AW) and functional decline. OBJECTIVE: This study aimed to examine the causes of ICU-AW and functional outcomes in critically ill patients with COVID-19 who required IMV. METHODS: This prospective, single-center, observational study included COVID-19 patients who required IMV for ≥48 h in the ICU between July 2020 and July 2021. ICU-AW was defined as a Medical Research Council sum score <48 points. The primary outcome was functional independence during hospitalization, defined as an ICU mobility score ≥9 points. RESULTS: A total of 157 patients (age: 68 [59-73] years, men: 72.6%) were divided into two groups (ICU-AW group; n = 80 versus non-ICU-AW; n = 77). Older age (adjusted odds ratio [95% confidence interval]: 1.05 [1.01-1.11], p = 0.036), administration of neuromuscular blocking agents (7.79 [2.87-23.3], p < 0.001), pulse steroid therapy (3.78 [1.49-10.1], p = 0.006), and sepsis (7.79 [2.87-24.0], p < 0.001) were significantly associated with ICU-AW development. In addition, patients with ICU-AW had significantly longer time to functional independence than those without ICU-AW (41 [30-54] vs 19 [17-23] days, p < 0.001). The development of ICU-AW was associated with delayed time to functional independence (adjusted hazard ratio: 6.08; 95% CI: 3.05-12.1; p < 0.001). CONCLUSIONS: Approximately half of the patients with COVID-19 requiring IMV developed ICU-AW, which was associated with delayed functional independence during hospitalization.

RESUMO

Aims: Functional decline due to skeletal muscle abnormalities leads to poor outcomes in patients with acute heart failure (AHF). The 6-minute walking test (6MWT) reliably evaluates functional capacity, but its technical difficulty for the elderly often limits its benefits. Although the Short Physical Performance Battery (SPPB) is a comprehensive measure of physical performance, its role in AHF remains unclear. This study aimed to examine the prognostic significance of SPPB compared to the 6MWT in elderly patients hospitalized for AHF. Methods and results: We retrospectively analysed 1192 elderly patients with AHF whose SPPB and 6MWT were measured during the hospitalization. The primary outcome measure was defined as a composite of all-cause death and heart failure readmission until 1 year after discharge. Patients with lower SPPB scores (0-6, n = 373) had significantly poorer outcomes than those with higher SPPB scores (7-12, n = 819) even after multivariable adjustment [adjusted hazard ratio (HR) 1.28, 95% confidence interval (CI) 1.01-1.61; P = 0.049], similar to those with shorter 6MWT (
