Background: Influenza vaccination varies widely across long-term care facilities (LTCFs) due to staff behaviors, LTCF practices, and patient factors. It is unclear how seasonal LTCF vaccination varies between cohabitating but distinct short-stay and long-stay residents. Thus, we assessed the correlation of LTCF vaccination between these populations and across seasons.Methods: The study design is a national retrospective cohort using Medicare and Minimum Data Set (MDS) data. Participants include U.S. LTCFs. Short-stay and long-stay Medicare-enrolled residents age ≥ 65 in U.S. LTCFs from a source population of residents during October 1st-March 31st in 2013-2014 (3,042,881 residents; 15,683 LTCFs) and 2014-2015 (3,143,174, residents; 15,667 LTCFs). MDS-assessed influenza vaccination was the outcome. Pearson correlation coefficients were estimated to assess seasonal correlations between short-stay and long-stay resident vaccination within LTCFs.Results: The median proportion of short-stay residents vaccinated across LTCFs was 70.4% (IQR, 50.0-82.7%) in 2013-2014 and 69.6% (IQR, 50.0-81.6%) in 2014-2015. The median proportion of long-stay residents vaccinated across LTCFs was 85.5% (IQR, 78.0-90.9%) in 2013-2014 and 84.6% (IQR, 76.6-90.3%) in 2014-2015. Within LTCFs, there was a moderate correlation between short-stay and long-stay vaccination in 2013-2014 (r = 0.50, 95%CI: 0.49-0.51) and 2014-2015 (r = 0.53, 95%CI: 0.51-0.54). Across seasons, there was a moderate correlation for LTCFs with short-stay residents (r = 0.54, 95%CI: 0.53-0.55) and a strong correlation for those with long-stay residents (r = 0.68, 95%CI: 0.67-0.69).Conclusions: In LTCFs with inconsistent influenza vaccination across seasons or between populations, targeted vaccination protocols for all residents, regardless of stay type, may improve successful vaccination in this vulnerable patient population.

Background We sought to determine if racial differences in influenza vaccination among nursing home (NH) residents during the 2008–2009 influenza season persisted in 2018–2019. Methods We conducted a cross-sectional study of NHs certified by the Centers for Medicare & Medicaid Services during the 2018–2019 influenza season in US states with ≥1% Black NH residents and a White–Black gap in influenza vaccination of NH residents (N = 2 233 392) of at least 1 percentage point (N = 40 states). NH residents during 1 October 2018 through 31 March 2019 aged ≥18 years and self-identified as being of Black or White race were included. Residents' influenza vaccination status (vaccinated, refused, and not offered) was assessed. Multilevel modeling was used to estimate facility-level vaccination status and inequities by state. Results The White–Black gap in influenza vaccination was 9.9 percentage points. In adjusted analyses, racial inequities in vaccination were more prominent at the facility level than at the state level. Black residents disproportionately lived in NHs that had a majority of Blacks residents, which generally had the lowest vaccination. Inequities were most concentrated in the Midwestern region, also the most segregated. Not being offered the vaccine was negligible in absolute percentage points between White residents (2.6%) and Black residents (4.8%), whereas refusals were higher among Black (28.7%) than White residents (21.0%). Conclusions The increase in the White–Black vaccination gap among NH residents is occurring at the facility level in more states, especially those with the most segregation. [ABSTRACT FROM AUTHOR]

Objectives: Estimates of influenza vaccine use are not available at the county level for U.S. nursing home (NH) residents but are critically necessary to guide the implementation of quality improvement programs aimed at increasing vaccination. Furthermore, estimates that account for differences in resident characteristics between counties are unavailable. We estimated risk‐standardized vaccination rates (RSVRs) among short‐ and long‐stay NH residents by U.S. county and identified drivers of geographic variation. Methods: We conducted a retrospective cohort study utilizing 100% of 2013–2015 fee‐for‐service Medicare claims, Minimum Data Set assessments, Certification and Survey Provider Enhanced Reports, and Long‐Term Care: Facts on Care in the U.S. We separately evaluated short‐stay (<100 days) and long‐stay (≥100 days) residents aged 65 and older across the 2013–2014 and 2014–2015 influenza seasons. We estimated RSVRs via hierarchical logistic regression adjusting for 32 resident‐level covariates. We then used multivariable linear regression models to assess associations between county‐level NHs predictors and RSVRs. Results: The study cohort consisted of 2,817,217 residents in 14,658 NHs across 2798 counties. Short‐stay residents had lower RSVRs than long‐stay residents (2013–2014: median [interquartile range], 69.6% [62.8–74.5] vs 84.0% [80.8–86.4]), and there was wide variation within each population (range, 11.4–89.8 vs 49.1–92.6). Several modifiable facility‐level characteristics were associated with increased RSVRs, including higher registered nurse to total nurse ratio and higher total staffing for licensed practical nurses, speech‐language pathologists, and social workers. Characteristics associated with lower RSVRs included higher percentage of residents restrained, with a pressure ulcer, and NH‐level hospitalizations per resident‐year. Conclusions: Substantial county‐level variation in influenza vaccine use exists among short‐ and long‐stay NH residents. Quality improvement interventions to improve vaccination rates can leverage these results to target NHs located in counties with lower risk‐standardized vaccine use. [ABSTRACT FROM AUTHOR]

Background: Racial disparities in receipt of high-dose influenza vaccine (HDV) have been documented nationally, but whether small-area geographic variation in such disparities exists remains unknown. We assessed the distribution of disparities in HDV receipt between Black and White traditional Medicare beneficiaries vaccinated against influenza within states and hospital referral regions (HRRs)., Methods: We conducted a nationally representative retrospective cohort study of 11,768,724 community-dwelling traditional Medicare beneficiaries vaccinated against influenza during the 2015-2016 influenza season (94.3% White and 5.7% Black). Our comparison was marginalized versus privileged racial group measured as Black versus White race. Vaccination and type of vaccine were obtained from Medicare Carrier and Outpatient files. Differences in the proportions of individuals who received HDV between Black and White beneficiaries within states and HRRs were used to measure age- and sex-standardized disparities in HDV receipt. We restricted to states and HRRs with ≥ 100 beneficiaries per age-sex strata per racial group., Results: We detected a national disparity in HDV receipt of 12.8 percentage points (pps). At the state level, the median standardized HDV receipt disparity was 10.7 pps (minimum, maximum: 2.9, 25.6; n = 30 states). The median standardized HDV receipt disparity among HRRs was 11.6 pps (minimum, maximum: 0.4, 24.7; n = 54 HRRs)., Conclusion: Black beneficiaries were less likely to receive HDV compared to White beneficiaries in almost every state and HRR in our analysis. The magnitudes of disparities varied substantially across states and HRRs. Local interventions and policies are needed to target geographic areas with the largest disparities to address these inequities., (© 2023. W. Montague Cobb-NMA Health Institute.)

Objectives: This study aimed to assess the distribution of racial disparities in influenza vaccination between White and Black short-stay and long-stay nursing home residents among states and hospital referral regions (HRRs)., Design: Retrospective cohort study., Setting and Participants: We included short-stay and long-stay older adults residing in US nursing homes during influenza seasons between 2011 and 2018. Included residents were aged ≥65 years and enrolled in Traditional Medicare. Analyses were conducted using resident-seasons, whereby residents could contribute to one or more influenza seasons if they resided in a nursing home across multiple seasons., Methods: Our comparison of interest was marginalized vs privileged racial group membership measured as Black vs White race. We obtained influenza vaccination documentation from resident Minimum Data Set assessments from October 1 through June 30 of a particular influenza season. Nonparametric g-formula was used to estimate age- and sex-standardized disparities in vaccination, measured as the percentage point (pp) difference in the proportions of individuals vaccinated between Black and White nursing home residents within states and HRRs., Results: The study included 7,807,187 short-stay resident-seasons (89.7% White and 10.3% Black) in 14,889 nursing homes and 7,308,111 long-stay resident-seasons (86.7% White and 13.3% Black) in 14,885 nursing homes. Among states, the median age- and sex-standardized disparity between Black and White residents was 10.1 percentage points (pps) among short-stay residents and 5.3 pps among long-stay residents across seasons. Among HRRs, the median disparity was 8.6 pps among short-stay residents and 5.0 pps among long-stay residents across seasons., Conclusions and Implications: Our analysis revealed that the magnitudes of vaccination disparities varied substantially across states and HRRs, from no disparity in vaccination to disparities in excess of 25 pps. Local interventions and policies should be targeted to high-disparity geographic areas to increase vaccine uptake and promote health equity., (Copyright © 2023 The Authors. Published by Elsevier Inc.

Objective: To identify whether differences in antibiotic prescribing practices by prescriber type and specialization in nursing home (NH) care exist for urinary tract infection (UTI) and pneumonia., Design: Retrospective cohort., Setting and Participants: This national study included antibiotic dispensings to traditional Medicare beneficiaries aged ≥65 years with UTI or pneumonia infections residing long-term (≥100 days) in US NHs between 2016 and 2018., Methods: Minimum Data Set assessment data were linked to Medicare data [Part D prescription drug, inpatient hospital (MedPAR), prescriber characteristics, and enrollment]. We compared antibiotic prescribing patterns by prescriber type [physician vs advanced practice practitioner (AP)] and NH specialization (≥90% vs <90% of all associated medication dispensings to NH residents). Antibiotic dispensing measures included the total number of dispensings and duration of therapy (median number of days supplied) by antibiotic class., Results: There were 264,735 antibiotic dispensings prescribed by 32,437 prescribers for 140,360 residents in 14,035 NHs. NH specialists were less likely to prescribe fluoroquinolones for UTI (22.9% NH specialist physician, 23.9% non-NH specialist physician, 21.3% NH specialist AP, 24.2% non-NH specialist AP), but more likely to prescribe fluoroquinolones for pneumonia (38.9%, 37.8%, 38.8%, 37.3%, respectively). Over time, NH specialists reduced fluoroquinolone prescribing for pneumonia to a greater extent than non-NH specialists. The duration of therapy was similar across prescriber groups for UTI, but longer among non-NH specialist APs for several antibiotic classes for pneumonia, including tetracyclines, glycopeptides and lipoglycopeptides, and metronidazole., Conclusions and Implications: There were differences in antibiotic prescribing patterns by prescriber type and specialization in NH care between 2016 and 2018. Understanding how antibiotic prescribing differs based on prescriber characteristics is essential to inform antibiotic stewardship efforts. Tailoring antibiotic stewardship efforts to prescribers by NH specialization is rational given differences in antibiotic prescribing patterns based on NH specialization., Competing Interests: Disclosure A.R.Z. reports grants from Sanofi for collaborative research on the epidemiology of infections and vaccinations in older nursing home residents and infants.

Objectives: Little is known about how COVID-19 treatment patterns have evolved over time in nursing homes (NHs) despite the devastating effects of COVID-19 in this setting. The aim was to describe changes in COVID-19-related medication use over time among NH residents in the United States., Design: Retrospective cohort study., Setting and Participants: This study used electronic health records (EHR) from 11 different US NH corporations between January 1, 2018, and March 31, 2022., Methods: The use of medications approved for COVID-19-related conditions or known to be used off-label for COVID-19 during the study period is identified. We described trends in the use of each drug and combined use per 1000 NH residents over calendar time [quarters (Q)]., Results: A total of 59,022 unique residents with the use of an eligible medication were identified. Hydroxychloroquine use sharply increased from 9.8 in 2020Q1 to 30.2 orders per 1000 individuals in 2020Q2. Dexamethasone use increased sharply from 14.8 in 2020Q2 to a peak of 121.9 orders per 1000 individuals in 2020Q4. Azithromycin use increased from 44.1 in 2019Q3 to a peak of 99.9 orders per 1000 individuals in 2020Q4, with a drop in 2020Q3 of 51.3 per 1000 individuals in 2020Q3. Concurrent use of azithromycin and hydroxychloroquine increased sharply from 0.3 in 2020Q1 to 10.6 orders per 1000 residents in 2020Q2 and then drastically decreased to 0.6 per 1000 residents in 2020Q3. Concurrent use of dexamethasone and azithromycin rose considerably from 0.7 in 2020Q2 to 28.2 orders per 1000 residents in 2020Q4., Conclusions and Implications: As in other settings, COVID-19-related medication use in NHs appears to have changed in response to the shifting evidence base and availability of medications during the pandemic. Providers should continue to diligently modify their prescribing as new evidence accrues., (Copyright © 2023 AMDA – The Society for Post-Acute and Long-Term Care Medicine. Published by Elsevier Inc.

Objectives: Quantify the relationship between increasing influenza and respiratory syncytial virus (RSV) community viral activity and cardiorespiratory rehospitalizations among older adults discharged to skilled nursing facilities (SNFs)., Design: Retrospective cohort., Setting and Participants: Adults aged ≥65 years who were hospitalized and then discharged to a US SNF between 2012 and 2015., Methods: We linked Medicare Provider Analysis and Review claims to Minimum Data Set version 3.0 assessments, PRISM Climate Group data, and the Centers for Disease Control and Prevention viral testing data. All data were aggregated to US Department of Health and Human Services regions. Negative binomial regression models quantified the relationship between increasing viral activity for RSV and 3 influenza strains (H1N1pdm09, H3N2, and B) and cardiorespiratory rehospitalizations from SNFs. Incidence rate ratios described the relationship between a 5% increase in circulating virus and the rates of rehospitalization for cardiorespiratory outcomes. Analyses were repeated using the same model, but influenza and RSV were considered "in season" or "out of season" based on a 10% positive testing threshold., Results: Cardiorespiratory rehospitalization rates increased by approximately 1% for every 5% increase in circulating influenza A(H3N2), influenza B, and RSV, but decreased by 1% for every 5% increase in circulating influenza A(H1N1pdm09). When respiratory viruses were in season (vs out of season), cardiorespiratory rehospitalization rates increased by approximately 6% for influenza A(H3N2), 3% for influenza B, and 5% for RSV, but decreased by 6% for influenza A(H1N1pdm09)., Conclusions and Implications: The respiratory season is a particularly important period to implement interventions that reduce cardiorespiratory hospitalizations among SNF residents. Decreasing viral transmission in SNFs through practices such as influenza vaccination for residents and staff, use of personal protective equipment, improved environmental cleaning measures, screening and testing of residents and staff, surveillance of viral activity, and quarantining infected individuals may be potential strategies to limit viral infections and associated cardiorespiratory rehospitalizations., (Copyright © 2022 The Authors.
