This report describes the effectiveness of second COVID-19 booster doses against infection, hospitalization, and death among nursing home residents.

Background: The impact of the COVID-19 pandemic on participation in and availability of cardiac rehabilitation (CR) is unknown. Methods: Among eligible Medicare fee-for-service beneficiaries, we evaluated, by month, the number of CR sessions attended per 100 000 beneficiaries, individuals eligible to initiate CR, and centers offering in-person CR between January 2019 and December 2021. We compared these outcomes between 2 periods: December 1, 2019 through February 28, 2020 (period 1, before declaration of the pandemic-related national emergency) and October 1, 2021 through December 31, 2021 (period 2, the latest period for which data are currently available). Results: In period 1, Medicare beneficiaries participated in (mean±SD) 895±84 CR sessions per 100 000 beneficiaries each month. After the national emergency was declared, CR participation sharply declined to 56 CR sessions per 100 000 beneficiaries in April 2020. CR participation recovered gradually through December 2021 but remained lower than prepandemic levels (period 2: 698±29 CR sessions per month per 100 000 beneficiaries, P =0.02). Declines in CR participation were most marked among dual Medicare and Medicaid enrollees and patients residing in rural areas or socially vulnerable communities. There was no statistically significant change in CR eligibility between the 2 periods. Compared with 2618±5 CR centers in period 1, there were 2464±7 in period 2 ( P <0.01). Compared with CR centers that survived the pandemic, 220 CR centers that closed were more likely to be affiliated with public hospitals, located in rural areas, and serve the most socially vulnerable communities. Conclusions: The COVID-19 pandemic was associated with a persistent decline in CR participation and the closure of CR centers, which disproportionately affected rural and low-income patients and the most socially vulnerable communities. Innovation in CR financing and delivery is urgently needed to equitably enhance CR participation among Medicare beneficiaries.

Background: Influenza leads in preventable infection-related hospitalization in nursing home (NH) residents. The adjuvanted trivalent influenza vaccine (aTIV) is more immunogenic than similarly dosed nonadjuvanted trivalent influenza vaccine (TIV), and observational studies suggest aTIV better prevents hospitalizations in older adults. We prospectively tested this in an NH setting. Methods: NHs with ≥50 long-stay residents aged ≥65 years were randomized to offer aTIV or TIV for residents for the 2016–2017 influenza season. Using intent-to-treat resident-level analysis with Cox proportional hazards regression models adjusted for clustering by facility and a priori baseline covariates (eg, age, heart failure, and facility-level characteristics), we assessed relative aTIV:TIV effectiveness for hospitalization (ie, all-cause, respiratory, and pneumonia and influenza [P&I]). Results: We randomized 823 NHs, housing 50 012 eligible residents, to aTIV or TIV. Residents were similar between groups by age (mean, ~79 years), heart failure, lung disease, and influenza and pneumococcal vaccine uptake, except aTIV homes housed fewer Black residents (14.5 vs 18.9%). Staff vaccine uptake was similar (~55%). P&I and all-cause resident hospitalization rates were lower (adjusted HR [aHR], .80 [95% CI, .66–.98; P = .03] and .94 [.89–.99; P = .02], respectively) for aTIV versus TIV, while the respiratory hospitalization rate was similar, in a season where vaccine effectiveness was considered poor. Conclusions: aTIV was more effective than TIV in preventing all-cause and P&I hospitalization from NHs during an A/H3N2-predominant season when TIV was relatively ineffective. Clinical Trials Registration: NCT02882100.

Nursing home residents have experienced substantial SARS-CoV-2–associated morbidity and mortality.^1,2 Resurgence with the Delta variant in the late summer and early autumn of 2021 and waning immunity among nursing home residents³ led the Centers for Disease Control and Prevention (CDC) to recommend a booster dose for those vaccinated with a 2-dose mRNA series.^4,5 The US Food and Drug Administration (FDA) amended the emergency use authorizations for the BNT162b2 vaccine (Pfizer-BioNTech) in September 2021 and the mRNA-1273 vaccine (Moderna) in October 2021. The FDA recommended a booster dose at least 6 months after receipt of the second dose of an mRNA vaccine for individuals at high risk, including those 65 years or older.⁶ Both mRNA vaccines were also authorized in August 2021 to be used for additional doses in immunocompromised individuals, which applied to many older adults in long-term care facilities. As of February 1, 2022, approximately 66% of US nursing home residents had received a booster dose.⁶
