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.
Using quantitative and qualitative approaches to understand racial disparities in adult vaccination
Journal of the National Medical Association, 2009
One proposed explanation for the persistence of racial disparities in adult immunizations is that minority patients receive primary care at practices that differ substantively from practices where white patients receive care. This study used both quantitative and qualitative methods to assess physician and practice factors contributing to disparities in a sample of inner-city, urban, and suburban practices in low to moderate income neighborhoods. Pneumococcal polysaccharide vaccine (PPV) and influenza vaccination rates were determined from medical record review in a sample of 2021 elderly (aged > or = 65 years) patients. Their physicians were surveyed about office systems for adult immunizations and structured observations of practice physical features, and operations were conducted. Case studies of practices with lowest and highest rates and the largest racial disparities are presented. Overall, weighted PPV vaccination rate was 60%, but rates differed significantly by race (65....
Decomposing Racial and Ethnic Disparities in Nursing Home Influenza Vaccination
Journal of the American Medical Directors Association, 2021
This study examines the racial/ethnic disparity among nursing home (NH) residents using a self-reported, validated measure of quality of life (QoL) among long-stay residents in Minnesota. Blinder-Oaxaca decomposition techniques determine which resident and facility factors are the potential sources of the racial/ethnic disparities in QoL. Black, Indigenous, and other People of Color (BIPOC) report lower QoL than White residents. Facility structural characteristics and being a NH with a high proportion of residents who are BIPOC are the factors that have the largest explanatory share of the disparity. Modifiable characteristics like staffing levels explain a small share of the disparity. To improve the QoL of BIPOC NH residents, efforts need to focus on addressing systemic disparities for NHs with a high proportion of residents who are BIPOC.
Racial similarities in response to standardized offer of influenza vaccination
Journal of General Internal Medicine, 2006
Despite known benefits of influenza vaccination and coverage by Medicare Part B, elderly minority patients are less likely to receive influenza vaccination than whites. To test whether a nonphysician-initiated standardized offer of influenza vaccination to all elderly primary care patients would result in similar proportions of African-American and white patients accepting vaccine. In 7 metropolitan Detroit primary care practices during the 2003 influenza vaccination season, medical assistants assessed influenza immunization status of all patients 65 years and older and collected limited demographic data. Eligible patients were offered vaccination. Proportion of patients accepting influenza vaccination by race and predictors of vaccine acceptance. Four hundred and fifty-four eligible patients with complete racial information were enrolled: 40% African American, 52% white, 8% other race/ethnicity. Similar proportions of African Americans and whites had already received the 2003 vaccine (11.6% and 11.0%, respectively) or stated vaccination as the reason for visit (23.8% and 30.5%, respectively). Among the remainder, there also were similar proportions who accepted vaccination: 68.9% white and 62.1% African-American patients. History of previous vaccination was the only statistically significant predictor of vaccine acceptance (odds ratio [OR] 8.64, 95% confidence interval [CI] 4.17, 17.91, P<.001). After adjusting for history of previous vaccination, age, gender, and education, the odds of vaccine acceptance were no different for whites and African Americans (OR 1.20, 95% CI 0.63, 2.29, P=.57). Vaccination acceptance differed little between African-American and white elderly patients. Using nonphysician personnel to identify and offer influenza vaccine to eligible patients is easily accomplished in primary care offices and has the potential to eliminate racial disparities in influenza vaccination.
Racial and ethnic disparities in influenza vaccination among elderly adults
Journal of General Internal Medicine, 2005
OBJECTIVES: To examine whether access to care factors account for racial/ethnic disparities in influenza vaccination among elderly adults in the United States. DESIGN: Indicators of access to care (predisposing, enabling, environmental/system, and health need) derived from Andersen's behavioral model were identified in the National Health Interview Survey questionnaire. The relationship of these indicators to influenza vaccination and race/ethnicity was assessed with multiple logistic regression models. MAIN RESULTS: Significant differences in vaccination were observed between non-Hispanic (NH) whites (66%) and Hispanics (50%, Po.001) and between NH whites (66%) and NH blacks (46%, Po.001). Controlling for predisposing and enabling access to care indicators, education, marital status, regular source of care, and number of doctor visits, reduced the prevalence odds ratios (POR) comparing Hispanics to non-Hispanic whites from 1.89 to 1.27. For NH blacks, controlling for access to care indicators changed the POR only from 2.24 (95% CI, 1.9 to 2.7) to 1.93 (95% CI, 1.6 to 2.4). CONCLUSIONS: This study confirmed the existence of sizable racial/ ethnic differences in influenza vaccination among elderly adults. These disparities were only partially explained by differences in indicators of access to care, especially among non-Hispanic blacks for whom large disparities remained. Factors not available in the National Health Interview Survey, such as patient attitudes and provider performance, should be investigated as possible explanations for the racial/ethnic disparity in influenza vaccination among non-Hispanic blacks.
Decomposing racial/ethnic disparities in influenza vaccination among the elderly
Vaccine, 2015
While persistent racial/ethnic disparities in influenza vaccination have been reported among the elderly, characteristics contributing to disparities are poorly understood. This study aimed to assess characteristics associated with racial/ethnic disparities in influenza vaccination using a nonlinear Oaxaca-Blinder decomposition method. We performed cross-sectional multivariable logistic regression analyses for which the dependent variable was self-reported receipt of influenza vaccine during the 2010-2011 season among community dwelling non-Hispanic African-American (AA), non-Hispanic White (W), English-speaking Hispanic (EH) and Spanish-speaking Hispanic (SH) elderly, enrolled in the 2011 Medicare Current Beneficiary Survey (MCBS) (un-weighted/weighted N=6,095/19.2million). Using the nonlinear Oaxaca-Blinder decomposition method, we assessed the relative contribution of seventeen covariates - including socio-demographic characteristics, health status, insurance, access, preference ...
Immunization Disparities in Older Americans
American Journal of Preventive Medicine, 2006
Background: Marked racial disparities persist in influenza and pneumococcal vaccinations among Medicare beneficiaries. This study sought to assess the contribution that patient, physician, health system, and area-level characteristics make to these racial disparities in immunization. Methods: Cross-sectional and decomposition analyses were performed on a nationally representative sample of 18,013 non-institutionalized Medicare beneficiaries who responded to the Medicare Current Beneficiary Survey (MCBS) in 2000 to 2002. The physician characteristics of interest included specialty type, accessibility, information-giving skills, perceived quality, and continuity of care. Health system characteristics included HMO enrollment and numbers of primary care physicians per elderly. The outcomes were receipt of influenza vaccine in the past year and ever having received a pneumococcal vaccine. Results: Immunization rates were below recommended levels for all Medicare beneficiaries. Disparities between white and black beneficiaries in the receipt of vaccinations were large-an absolute 17% difference for each vaccine. After adjusting for patient, physician, health system, and area-level characteristics, white beneficiaries had significantly higher odds of vaccination than did black beneficiaries: adjusted odds ratio (aOR)ϭ1.52 (95% confidence interval [CI]ϭ1.35-1.71) for influenza vaccination, and aORϭ1.82 (95% CIϭ1.61-2.07) for pneumococcal vaccination. Beneficiaries with a usual physician that they rated as having good information-giving skills and whose practice was more accessible, had higher immunization rates. Beneficiaries with a primary care generalist as their usual physician had higher odds of immunization than those with a specialist as their usual physician. At the county level, a higher number of primary care physicians per elderly resident was associated with higher odds of immunization. Only 7% of the racial disparity in influenza immunization was explained by the measured characteristics of beneficiaries and their health systems. Conclusions: Despite similar insurance coverage and presence of a usual physician, black beneficiaries were significantly less likely than their white counterparts to receive influenza and pneumococcal vaccinations. The implications for future research are discussed, including the need for system-based interventions that make the offering and discussion of vaccination routine.
