Covid-19 patients admitted to the intensive care unit of Selcuk University Hospital were included in the study. Clinical frailty score was given during admission to the intensive care unit. Demographic data, laboratory data, radiological imaging and vital signs of the patients were recorded. Treatment and patient positions were recorded during the intensive care follow-up of the patients. Mortality status of the patients 6 months after admission to the ICU was recorded.

It is planned to include non-pregnant and non-traumatic patients over the age of 18, diagnosed with COVID-19, who are treated in the Intensive Care Unit of Selcuk University Hospital. The frailty status will be evaluated by using the clinical frailty scale at the admission of the patients to the intensive care unit. Evaluation from the patient himself, if the consciousness of the patients is clear; If not, it will be done near the patient. Patients will be divided into two groups using the clinical frailty scale (CFS) as frail if the score is ≥5 and non-fragile if the score is <5. Demographic information and vaccination status (how many dose and type) will be questioned, SOFA score, APACHE II score will be recorded. Routine examinations made from the patient file; thorax computed tomography (CT) imaging, laboratory values, respiratory support information, drug treatments applied, patient positions will be recorded. Thoracic CT scans severity scores for each of the five lung lobes: 0 for no involvement (0%), 1 for minimal involvement (1%-25%), 2 for mild involvement (26-50%), 3 for moderate involvement (51%) -75) and 4 advanced involvement (76-100%). The total severity score will be the sum of the scores of the five lobes. If the score is ≤10, it will be considered as mild involvement, and if the score is >10, it will be considered as severe involvement. Laboratory values; platelet and lymphocyte count, albumin, sodium, ferritin, D-dimer, crp, procalcitonin, interleukin-6 and glomerular filtration rate values, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, CRP/Albumin ratio, arterial blood gas will be recorded. Whether or not he received respiratory support; type (invasive/non-invasive positive pressure respiratory support or high-flow nasal oxygen therapy), duration will be recorded. The use and duration of vasoactive drugs administered, renal replacement therapy and its durations will be recorded. Patient positions will be recorded as supine, lateral decubitus, and prone. The length of stay in the intensive care unit and mortality of the patients will be recorded. Comparisons will be made between frail and non-fragile groups on all these evaluated parameters.
