Changes in Physical Function and Physical Therapy Use in Older Veterans Not Infected by CoVID-19 Residing in Community Living Centers during the CoVID-19 Pandemic

Objectives: Examine physical function change and physical therapy (PT) use in short-stay and long-stay residents not infected by CoVID-19 within Veterans Affairs (VA) Community Living Centers (CLCs).

Design: Retrospective cohort study using Minimum Data Set (MDS) 3.0 assessments.

Settings and participants: 12,606 Veterans in 133 VA CLCs between September 2019 and September 2020.

Methods: Difference in physical function [MDS Activities of Daily Living Score (MDS-ADL)] and PT use (minutes in past 7 days) from admission to last assessment in a period were compared between the pre-CoVID-19 (September 2019 to February 2020) and early CoVID-19 (April 2020 to September 2020) period using mixed effects regression with multivariable adjustment. Assessments after a positive CoVID-19 test were excluded. Differences were examined in the sample and repeated after stratifying into short- and long-stay stratums.

Results: Veterans admitted during early CoVID-19 had more comorbidities, worse MDS-ADL scores, and were more often long-stay residents compared with those admitted during pre-CoVID-19. In comparison to pre-CoVID-19, Veterans in VA CLCs during early CoVID-19 experienced greater improvements in their MDS-ADL (-0.49 points, 95% CI -0.27, -0.71) and received similar minutes of therapy (2.6 minutes, 95% CI -0.8, 6.0). Stratification revealed short-stay residents had relative improvements in their function (-0.69 points, 95% CI -0.44, -0.94) and higher minutes of PT (5.1 minutes, 95% CI 0.9, 9.2) during early CoVID-19 whereas long-stay residents did not see differences in functional change (0.08 points, 95% CI -0.36, 0.51) or PT use (-0.6 minutes, 95% CI -6.1, 4.9).

Conclusions and implications: During early CoVID-19, physical function improved while the amount of PT received was maintained compared with pre-CoVID-19 for Veterans in VA CLCs. Short-stay residents experienced greater improvements in physical function and increases in PT use. These findings may be partly due to selection bias relating to Veterans admitted to CLCs during early CoVID-19.
