dataset with linked facility- and county-level data from the CMS Nursing Home COVID-19 Public File, Nursing Home Compare, Long-Term Care Focus, and The New York Times. Multivariable logistic regression evaluated the odds of COVID-19 infections, hospitalizations, and deaths in nursing homes. Among 13,156 nursing homes, 80.5% reported ≥1 COVID-19 cases; on average, nursing homes reported 4.5 hospitalizations and 3.0 deaths. Facilities with higher acuity patients, chain status, >150 beds, high percentage white residents, low Medicaid share, high surrounding county case rates, and occupancy rates >75% were signifcantly (p <.001) related to increased odds of all outcomes. N95 mask shortages continued to increase risk of cases and hospitaliza- tions. Five-Star ratings, high infuenza vaccination rates, and clinical staff shortages were not signifcant factors. Findings demonstrate that through 2020, nursing homes continued to face challenges protecting their residents from COVID-19- related morbidity and mortality. FACTORS ASSOCIATED WITH NURSING HOME RESIDENTS’ COVID-19 INFECTIONS: A SYSTEMATIC REVIEW OF LITERATURE CHENG YIN, 1 Xiaoli Li, 2 Rongfang Zhan, 1 and Liam ONeill, 3 1. University of North Texas, Corinth, Texas, United States, 2. University of North Texas, denton, Texas, United States, 3. University of North Texas, University of North Texas, Texas, United States Background: Nursing homes were impacted dispro- portionately by the coronavirus because of their resident’s vulnerabilities and settings. Even many previous studies il- lustrated factors related to nursing home residents’ Covid- 19 infections, there’s no such study epitomizing those factors systematically, while some factors were controversial in dif- ferent studies. The article aims to summarize major types of factors and provide crucially infuential implications for nursing homes to prevent and manage their resident infec- tions. Methods: All articles published between 01 January 2020 - 15 January 2021 in English version were searched through three electronic databases (PubMed, Web of Science, and Scopus). Two authors screened and evaluated a total of 121 studies independently based on selection and extraction criteria. Results: Seventeen identifed studies were included in the research, which involved fve major types of factors (nursing home’s residence, nursing home, staff, resident, and others). Conclusion: nursing home’s county infection rate, size, and staff residence were the strongest signifcant fac- tors in many studies. Per-capital income, symptom-based screening and testing, and asymptomatic individuals have impacted resident’s infections variously since the beginning of the pandemic. Nursing home’s star rating and a total count of fnes became factors when considered its locations. Other factors, including nursing home’s type, historical health de- fciencies, staffng level, and staff working different facilities, etc., were also signifcant factors. The value of factors sug- gests healthcare systems refect appropriate measures and al- locate more resources to nursing homes in high prevalence counties on the basis of universal allocation. NO INCREASE IN SHORT-TERM MORTALITY FOLLOWING COVID-19 VACCINATION AMONG NURSING HOME RESIDENTS Barbara Bardenheier, 1 Stefan Gravenstein, 2 Roee Gutman, 3 Neil Sarkar, 4 Richard Feifer, 5 Elizabeth White, 2 and Vincent Mor, 2 1.

Genesis HealthCare, Kennett Square, Pennsylvania, United States Reports of fatal adverse events following mRNA-based vaccination for COVID-19 in Norwegian nursing home (NH) residents have raised concern regarding vaccine safety in very old and frail persons. A limitation of these reports, however, is the absence of contemporaneous control groups, particularly given the high baseline mortality in this popula- tion. Using electronic health records’ data on resident deaths, hospital transfer, vaccination, and daily census from Genesis Healthcare, a large NH provider spanning 24 U.S. states, we compared 7-day mortality and hospitalization rates for vaccinated versus unvaccinated NH residents. Between December 18, 2020 and December 31, 2020, 7006 residents across 118 NHs were vaccinated with the frst dose. Mortality and hospital transfer rates within 7 days of vaccination were compared to rates for: (1) unvaccinated residents in the same facility within 7 days of the vaccine clinic (n=4414), and (2) residents in 166 yet-to-be-vaccinated facilities be- tween December 25, 2020 and January 1, 2021 (n=17,076). We excluded residents with a positive SARS-CoV-2 diag- nostic test within 20 days prior to their 7-day observation window. Mortality rates per 100,000 residents were lower among vaccinated (587, 95%CI: 431, 798) versus unvaccin- ated residents within the same facilities (984, 95%CI: 705, 1382), and compared to residents in not-yet-vaccinated fa- cilities (912, 95%CI: 770-1080), with overlapping 95% CIs. Hospital transfers were lower among vaccinated residents than in either comparison group, but with overlapping CIs. Our fndings suggest that short term mortality rates appear unrelated to vaccination for COVID-19 in NH residents, and should dispel concerns raised by previous reports.
