Wandering Behavior and SARS-CoV-2 Infection in Veterans Affairs Community Living Center Residents.

ABSTRACT

OBJECTIVE: Wandering behavior in nursing home (NH) residents could increase risk of infection. The objective of this study was to assess the association of wandering behavior with SARS-CoV-2 infection in Veterans Affairs (VA) Community Living Center (CLC) residents. DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: Veterans residing in 133 VA CLCs. METHODS: We included residents with SARS-CoV-2 test from March 1, 2020 to December 31, 2020 from VA electronic medical records. We identified CLC residents with wandering on Minimum Data Set 3.0 assessments and compared them with residents without wandering. The outcome was SARS-CoV-2 infection, as tested for surveillance testing, in those with and without wandering. Generalized linear model with Poisson link adjusted for relevant covariates was used. RESULTS: Residents (n = 9995) were included in the analytic cohort mean, (SD) age 73.4 (10.7); 388 (3.9%) women. The mean (SD) activities of daily living score in the overall cohort was 13.6 (8.25). Wandering was noted in 379 (3.8%) (n = 379) of the cohort. The exposure groups differed in prior dementia (92.6% vs 62.1%, standardized mean difference [SMD] = 0.8) and psychoses (41.4% vs 28.1%, SMD = 0.3). Overall, 12.5% (n = 1248) tested positive for SARS-CoV-2 and more residents among the wandering group were SARS-CoV-2 positive as compared with those in the group without wandering (19% [n = 72] vs 12.2% [n = 1176], SMD = 0.19). Adjusting for covariates, residents with wandering had 34% higher relative risk for SARS-CoV-2 infection (adjusted relative risk, 1.34; 95% CI, 1.04-1.69). CONCLUSIONS AND IMPLICATIONS CLC residents with wandering had a higher risk of SARS-CoV-2 infection. This may inform implementation of infection control and isolation policies as NHs attempt to balance ethical concepts of resident autonomy, proportionality, equity, and utilitarianism.
