Post-Intensive Care Syndrome in COVID-19 versus Non-COVID-19 Critical Illness Survivors: More Similar than Not?

Clinical Comparison of Post-intensive Care Syndrome and Long Coronavirus Disease

Post-intensive care syndrome (PICS) encompasses persistent physical, psychological, and cognitive impairments. The coronavirus disease of 2019 (COVID-19) pandemic highlighted parallels between PICS and "long COVID". There is an overlap between the 2 in risk factors, symptoms, and pathophysiology. Physical impairments in both include weakness and fatigue. Cognitive impairments include executive dysfunction in PICS and "brain fog" in long COVID. Mental health issues consist of depression, anxiety, and posttraumatic stress disorder in both disease states. Long COVID and PICS impact families, with multifaceted effects on physical health, mental well-being, and socioeconomic stability. Understanding these syndromes is crucial for comprehensive patient care and family support.

Predictors of Post-COVID-19 Functional Status Scale in Hospitalized Patients Recovering From SARS-CoV-2 Infection

OBJECTIVE

The study aimed to investigate whether peripheral and inspiratory muscle strength and architecture, functional capacity, functional mobility, fatigue, and health-related quality of life are predictors of the Post-COVID-19 Functional Status Scale score in patients with post-COVID-19 syndrome who were hospitalized.

DESIGN

A cross-sectional study included 69 patients (53.3 ± 13.2 yrs, 36 men) with post-COVID-19 syndrome. The following outcomes were assessed: peripheral (dynamometry) and inspiratory (manovacuometry) muscle strength, muscle architecture (ultrasound), functional capacity (six-minute walk test), functional mobility (Timed Up and Go), fatigue (Functional Assessment of Chronic Illness Therapy), health-related quality of life (36-item Short-Form Health Survey), and functional status (Post-COVID-19 Functional Status scale).

RESULTS

Functional mobility (β = 0.573, P < 0.001), vastus intermedius echogenicity (β = -0.491, P = 0.001), length of stay (β = 0.349, P = 0.007), and female sex (β = 0.415, P = 0.003) influenced the Post-COVID-19 Functional Status Scale.

CONCLUSIONS

Functional mobility, muscle quality of the vastus intermedius, length of stay, and female sex influence the Post-COVID-19 Functional Status Scale score in this population. It is noteworthy that functional mobility is an independent predictor of Post-COVID-19 Functional Status Scale.

One Year Overview and Follow-Up in a Post-COVID Consultation of Critically Ill Patients

The long-term clinical management and evolution of a cohort of critical COVID-19 survivors have not been described in detail. We report a prospective observational study of COVID-19 patients admitted to the ICU between March and August 2020. The follow-up in a post-COVID consultation comprised symptoms, pulmonary function tests, the 6-minute walking test (6MWT), and chest computed tomography (CT). Additionally, questionnaires to evaluate the prevalence of post-COVID-19 syndrome were administered at 1 year. A total of 181 patients were admitted to the ICU during the study period. They were middle-aged (median [IQR] of 61 [52;67]) and male (66.9%), with a median ICU stay of 9 (5–24.2) days. 20% died in the hospital, and 39 were not able to be included. A cohort of 105 patients initiated the follow-up. At 1 year, 32.2% persisted with respiratory alterations and needed to continue the follow-up. Ten percent still had moderate/severe lung diffusion (DLCO) involvement (<60%), and 53.7% had a fibrotic pattern on CT. Moreover, patients had a mean (SD) number of symptoms of 5.7 ± 4.6, and 61.3% met the criteria for post-COVID syndrome at 1 year. During the follow-up, 46 patients were discharged, and 16 were transferred to other consultations. Other conditions, such as emphysema (21.6%), COPD (8.2%), severe neurocognitive disorders (4.1%), and lung cancer (1%) were identified. A high use of health care resources is observed in the first year. In conclusion, one-third of critically ill COVID-19 patients need to continue follow-up beyond 1 year, due to abnormalities on DLCO, chest CT, or persistent symptoms.
