[Biopsychosocial Factors Influencing Mortality and Functional Recovery in COVID-19 Patients Undergoing Prone Positioning: A Prospective Observational Study]

Abstract

Patients placed in a prone position due to COVID-19 present a more severe disease, longer stay in ICU and have more significant complications associated with positioning than other patients.

Aim: To identify social, health, and hospital factors associated with mortality and functional recovery in activities of daily living (ADL) in patients admitted to the ICU due to COVID-19 who were in the prone position.

Methods: We conducted a prospective observational study between June 2021 and March 2022 at the San José Clinical Hospital. The study included people 18 years of age or older admitted to the ICU due to COVID-19 who were in the prone position. Using logistic regression, we searched for factors associated with the risk of in-hospital mortality. Using linear regression, we also analyzed factors associated with functional recovery in ADL at discharge and post-discharge.

Results: In 85 patients included, being men, older age, history of mental health, cardiorespiratory disease, and living in a commune of high social priority were associated with a higher risk of in-hospital mortality. A greater number of days of hospitalization was associated with less functional recovery at discharge and post-discharge. In contrast, more cycles in prone position during hospitalization and higher education level were associated with greater post-discharge functional recovery.

Conclusions: The survival and functional prognosis of patients with severe COVID-19 can be predicted early through a biopsychosocial evaluation of their characteristics. Intrahospital actions could improve functional recovery in ADL in the short term in critically ill patients surviving COVID-19.
