Evaluation of a state-wide effort to improve COVID-19 infection control in Massachusetts nursing homes.

BACKGROUND: During the deadly 2020 SARS-CoV-2 surge in nursing homes (NHs), Massachusetts (MA) initiated a multicomponent infection control intervention to mitigate its spread. METHODS: We aimed to assess the intervention's impact by comparing the weekly risk of PCR-confirmed infections among MA NH residents to those in neighboring New England states, all managed similarly by a single NH provider. We studied 2085 residents in 20 MA NHs and 4493 residents in 45 comparator facilities. The intervention included: (1) A 28-item infection control checklist of best practices, (2) incentive payments to NHs contingent on scoring ≥24 on the checklist, meeting 6 core competencies, testing residents and staff for SARS-COV-2 RNA, uploading data, and enabling virtual visits; (3) on-site and virtual infection control consultations for deficient facilities; (4) 6 weekly webinars; (5) continuous communication with the MA Department of Public Health; and (6) access to personal protective equipment, temporary staff, and SARS-CoV-2 testing. Weekly rates of infection were adjusted for county COVID-19 prevalence. RESULTS: The adjusted risk of infection started higher in MA, but declined more rapidly in its NHs compared to similarly managed facilities in other states. The decline in infection risk during the early intervention period was 53% greater in MA than in Comparator States (state-by-time interaction HR = 0.47; 95% CI 0.37-0.59). By the late intervention period, the risk of infection continued to decline in both groups, and the change from baseline in MA was marginally greater than that in the Comparator States (interaction HR 0.80; 95% CI 0.64-1.00). CONCLUSIONS: The MA NH intervention was associated with a more rapid reduction in the rate of SARS-CoV-2 infections compared to similarly managed NHs in neighboring states. Although several unmeasured factors may have confounded our results, implementation of the MA model may help rapidly reduce high rates of infection and prevent future COVID-19 surges in NHs.

The Effect of Race and Dementia Prevalence on a COVID-19 Infection Control Intervention in Massachusetts Nursing Homes.

BACKGROUND: Nursing home (NH) residents, especially those who were Black or with dementia, had the highest infection rates during the COVID-19 pandemic. A 9-week COVID-19 infection control intervention in 360 Massachusetts NHs showed adherence to an infection control checklist with proper personal protective equipment (PPE) use and cohorting was associated with declines in weekly infection rates. NHs were offered weekly webinars, answers to infection control questions, resources to acquire PPE, backup staff, and SARS-CoV-2 testing. We asked whether the effect of this intervention differed by racial and dementia composition of the NHs. METHODS: Data were obtained from 4 state audits using infection control checklists, weekly infection rates, and Minimum Data Set variables on race and dementia to determine whether adherence to checklist competencies was associated with decline in average weekly rates of new COVID-19 infections. RESULTS: Using a mixed-effects hurdle model, adjusted for county COVID-19 prevalence, we found the overall effect of the intervention did not differ by racial composition, but proper cohorting of residents was associated with a greater reduction in infection rates among facilities with ≥20% non-Whites (n = 83). Facilities in the middle (>50%-62%; n = 121) and upper (>62%; n = 115) tertiles of dementia prevalence had the largest reduction in infection rates as checklist scores improved. Cohorting was associated with greater reductions in infection rates among facilities in the middle and upper tertiles of dementia prevalence. CONCLUSIONS: Adherence to proper infection control procedures, particularly cohorting of residents, can reduce COVID-19 infections, even in facilities with high percentages of high-risk residents (non-White and dementia).

Reliability of Virtual Physical Performance Assessments in Veterans During the COVID-19 Pandemic.

OBJECTIVE: To determine the reliability of 3 physical performance tests performed via a telehealth visit (30-s arm curls test, 30-s chair stand test, 2-min step test) among community-dwelling older veterans. DESIGN: Cross sectional study. SETTING: Virtual. PARTICIPANTS: Veterans (N=55; mean age 75y) who enrolled in Gerofit, a virtual group exercise program. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Participants were tested by 2 different assessors at 1 time point. The intraclass correlation coefficient (ICC) with 95% confidence intervals and Bland-Altman plots were used as measures of reliability. To assess generalizability, ICCs were further evaluated by health conditions (type 2 diabetes, arthritis, obesity, depression). RESULTS: Assessments were conducted among 55 participants. The ICC was above 0.98 for all 3 tests across health conditions and Bland-Altman plots indicated that there were no significant systematic errors in the measurement. CONCLUSIONS: The virtual physical performance measures appear to have high reliability and the findings are generalizable across health conditions among veterans. Thus, they are reliable for evaluating physical performance in older veterans in virtual settings.
