Impact on Mental, Physical, And Cognitive Functioning of a Critical Care sTay During the COVID-19 Pandemic

The WHODAS 2.0 is a self-reported disability questionnaire based on the International Classification of Functioning, Disability, and Health (ICF). It includes 36 questions, organised under six domains (cognition, mobility, self-care, getting along, life activities and participation). Each question must be answered based on the perceived difficulty for performing activities using a 5-point scale (none, mild, moderate, severe and extreme). The overall score of each domain, it is transformed into a score between 0 and 100, where 0 means no disability and 100 is complete disability

The CFS evaluates specific domains including physical functioning, activities of daily living (ADL), instrumental ADL, assistance for personal care, comorbidities, and cognition to generate a frailty score using a 9-point scale ranging from 1 (very fit) to 9 (terminally ill). A score greater than 4 is considered fragile

the MRC-SS consists of a standardised examination of six muscle groups bilaterally (i.e. shoulder abduction, elbow flexion, wrist extension, hip flexion, knee extension and dorsiflexion). All muscle groups are scored using a 6-point scale between 0 and 5 (0 = no visible /palpable contraction; 1 = visible / palpable contraction or no limb movement; 2 = limb movement, but not against gravity; 3 = movement against the gravity over nearly the entire range of motion; 4 = motion against gravity and resistance, subjectively adjusted for gender and age; 5 = normal force). The score goes from 0 (no strength) to a maximum score of 60 points, indicating normal peripheral strength.

The FSS-ICU is a mobility instrument to score the level of physical assistance required when performing five functional activities: rolling, transfer from supine to sit, sitting at the edge of the bed, transfer from sitting to stand, and walking. Each activity is scored using a 7-point scale ranging from 0 (not able to perform) to 7 (complete independence). The resulting overall score ranges from 0 to 35 points, where a higher scores indicates better performance.

The MoCA blind is a cognitive screening tool designed to detect cognitive dysfunction in five areas: memory, attention, language, abstraction and orientation. Each domain is scored separately for a total score ranging from 0 to 22 points. A score equal to or greater than 18 points is considered normal cognition.

The HADS is an interviewer or self-administered questionnaire designed to identify anxiety and depressive symptoms in a wide variety of in-hospital patients, which requires between 2 and 5 minutes to be completed. The HADS has fourteen questions, seven for anxiety and seven for depressive symptoms. Each question is rated with a 4-point scale ranging from 0 ("absence") to 3 ("extreme presence"), resulting in a sum score of 21 points per subscale. For each subscale, a score >8 indicates suspected anxiety or depression, while a score >11 indicates clinical symptoms of anxiety or depression.

The IES-R is an interviewer or self-administered questionnaire designed to measure the subjective distress caused by traumatic events that has been validated for critical illness survivors. It comprises 22 questions in three subscales: intrusion, avoidance, and hyperarousal. Questions are rated on a 5-point scale ranging from 0 ("not at all") to 4 ("extremely"). The score goes from 0 to 88 points. Scores above 33 are indicative of post-traumatic stress symptoms.

The EQ-5D-3L is an interviewer or self-administered questionnaire of health status or health-related quality of life, including five domains: mobility, self-care, usual activities, pain/discomfort, anxiety/depression and global health state. Each domain is scored based on 3 levels of severity: no problems, some problems, and extreme problems. Each combination of answers can be translated into a utility score, where 0 is similar to being dead and 1 represents the best possible quality of life. The utility scores were obtained using the Chilean Social valuation of EQ-5D health states (DOI: http://dx.doi.org/10.1016/j.jval.2011.09.002)

The employment status was evaluated using the following questions: What is your current employment status? What working hours do you have? and has your employment situation changed after your ICU stay?
