Application of the Perme Score to assess mobility in patients with COVID-19 in inpatient units

To evaluate the ability of the Perme Score to detect changes in the level of mobility of patients with COVID-19 outside the intensive care unit.

A retrospective cohort study was conducted in inpatient units of a private hospital. Patients older than 18, diagnosed with COVID-19, who were discharged from the intensive care unit and remained in the inpatient units were included. The variables collected included demographic characterization data, length of hospital stay, respiratory support, Perme Score values at admission to the inpatient unit and at hospital discharge and the mobilization phases performed during physical therapy.

A total of 69 patients were included, 80% male and with a mean age of 61.9 years (SD=12.5 years). The comparison of the Perme Score between the times of admission to the inpatient unit and at hospital discharge shows significant variation, with a mean increase of 7.3 points (95%CI:5.7-8.8; p<0.001), with estimated mean values of Perme Score at admission of 17.5 (15.8; 19.3) and hospital discharge of 24.8 (23.3; 26.3). There was no association between Perme Score values and length of hospital stay (measure of effect and 95%CI 0.929 (0.861; 1.002; p=0.058)).

The Perme Score proved effective for assessing mobility in patients diagnosed with COVID-19 with prolonged hospitalization outside the intensive care setting. In addition, we demonstrated by the value of the Perme Score that the level of mobility increases significantly from the time of admission to inpatient units until hospital discharge. There was no association between the Perme Score value and length of hospital stay.
