Características clínicas e desfechos de saúde em pacientes internados por COVID-19 – estudo observacional retrospectivo com foco na mobilidade

Abstract

Introduction: Previous studies on patients hospitalized for COVID-19 have shown that they have impaired mobility, however, so far, little data has been released regarding the characteristics of physical mobility of these patients who were hospitalized either in wards or ICUs, as well as on the possible relationship with clinical outcomes. Objective: to investigate clinical characteristics and health outcomes in patients according to their mobility on admission and discharge from hospital due to COVID-19. Methods: Retrospective observational study with the characteristics involving patients admitted to a hospital affected by the SARS-CoV-2 virus. The patients were analyzed in terms of mobility and the classification was made according to the protocol by Morris et al 2008 (figure 1) following the evolution of health professionals through the electronic medical record at the time of admission and discharge. Health outcomes were considered: length of hospital stay in the ICU or ward (in number of days), need for mechanical ventilation (in days), need for prone position, if there was extubation failure (considering a time ≤48hrs after extubation) , need for tracheostomy, occurrence of cardiovascular events, septic shock, renal failure, cardiorespiratory arrest and in-hospital death. Results: A total of 30 patients were evaluated, 50% were women. The main comorbidity was SAH, and the main symptoms were cough and dyspnea. As clinical outcomes, 26 patients were using oxygen therapy, 4 required invasive mechanical ventilation and one died. In the correlation between clinical outcomes and mobility, we found a negative correlation between the need for ICU admission and greater mobility on admission (r: -0.36; p=0.04). Conclusion: We concluded that patients hospitalized due to complications from COVID19 had less mobility on admission compared to hospital discharge.
