The Influence Of Covid-19 On Patient Mobilization And Injury Attributes In The ICU: A Retrospective Analysis Of A Level II Trauma Center

Abstract

The objectives of this study were to determine the effect of COVID-19 on physical therapy (PT) mobilization of traumatically-injured patients and to determine if mobilization affected patient course in the ICU. This retrospective study included patients who were admitted to the ICU of a level II trauma center. The patients were divided into two groups, i.e., those admitted before (n=378) and after (n=499) April 1, 2020 when Georgia’s COVID-19 Shelter-in-place order was mandated. The two groups were contrasted on nominal and ratio variables using Chi-square and Student’s t-tests. A secondary analysis focused specifically on the after COVID patients examined the extent to which mobilization (n=328) or lack of mobilization (n=171) influenced ICU outcomes (e.g., mortality, readmission). The two groups were contrasted on nominal and ratio variables using Chi-square and Student’s -tests. The after COVID patients had higher injury severity as a greater proportion was classified as severely injured (i.e., >15 on Injury Severity Score) compared to the before COVID patients. After COVID patients also had greater cumulative number of comorbidities and experienced greater complications in the ICU. Despite this, there was no difference between patients in receiving a PT consultation or day-to-mobilization. Within the after COVID cohort, those that were mobilized were older, a higher proportion were female, they had greater Glasgow Coma Scale scores, had longer total hospital days, and a lesser mortality rate. Despite shifting patient injury attributes post-COVID-19, a communicable disease, mobilization care remained consistent and effective.Level of EvidenceLevel III
