Racial differences in hepatitis C treatment eligibility.

ABSTRACT: Black Americans are disproportionally infected with hepatitis C virus (HCV) and are less likely than whites to respond to treatment with peginterferon (PEG-IFN) plus ribavirin (RBV). The impact of race on HCV treatment eligibility is unknown. We therefore performed a retrospective analysis of a phase 3B multicenter clinical trial conducted at 118 United States community and academic medical centers to evaluate the rates of and reasons for HCV treatment ineligibility according to self-reported race. In all, 4,469 patients were screened, of whom 1,038 (23.2%) were treatment ineligible. Although blacks represented 19% of treated patients, they were more likely not to be treated due to ineligibility and/or failure to complete required evaluations (40.2%) than were nonblack patients (28.5%; P < 0.001). After the exclusion of persons not treated due to undetectable HCV RNA or nongenotype 1 infection, blacks were 65% less likely than nonblacks to be eligible for treatment (28.1% > 17.0%; relative risk, 1.65; 95% confidence interval, 1.46-1.87; P < 0.001). Blacks were more likely to be ineligible due to neutropenia (14% versus 3%, P < 0.001), anemia (7% versus 4%, P = 0.02), elevated glucose (8% versus 3%, P < 0.001), and elevated creatinine (5% versus 1%, P < 0.001).Largely due to a higher prevalence of neutropenia and uncontrolled medical conditions, blacks were significantly less likely to be eligible for HCV treatment. Increased access to treatment may be facilitated by less conservative neutrophil requirements and more effective care for chronic diseases, namely, diabetes and renal insufficiency.

Project description:To determine whether (1) black and white women with endometrial cancer were treated by different surgical specialties and in different types of hospitals and (2) differences in specialty and hospital type contributed to racial differences in survival.Retrospective cohort study of 12,307 women aged 65 years and older who underwent surgical treatment of endometrial cancer between 1991 and 1999 in the 11 Surveillance Epidemiology and End Results registries.Black women were more likely to have a gynecologic oncologist to perform their surgery and to be treated at hospitals that were higher volume, larger, teaching, National Cancer Institute centers, urban, and where a greater proportion of the surgeries were performed by a gynecologic oncologist. In unadjusted models, black women were over twice as likely as white women who died because of cancer (hazards ratio [HR]: 2.33), but nearly all of the initial racial difference in survival was explained by differences in cancer stage, and grade as well as age and comorbidities at presentation (adjusted HR: 1.10). Surgical specialty was not associated with survival and, of the hospital characteristics studied, only surgical volume was associated with survival (P < 0.005). Adjusting for hospital characteristics did not change the racial difference in survival (HR: 1.10). Adjustment for the specific hospital where the woman was treated eliminated the association between race and surgeon specialty and slightly widened the residual racial difference in survival (HR: 1.23 vs. 1.10).In contrast to several studies suggesting that blacks with breast cancer, colon cancer, or cardiovascular disease are treated in hospitals with lower quality indicators, black women diagnosed with endometrial cancer in Surveillance Epidemiology and End Results regions between 1991 and 1999 were more likely to be treated by physicians with advanced training and in high volume, large, urban, teaching hospitals. However, except for a modest association with hospital surgical volume, these provider and hospital characteristics were largely unrelated to survival for women with endometrial cancer. The great majority of the difference in survival was explained by differences in tumor and clinical characteristics at presentation.

Project description:ImportancePulse oximetry guides triage and therapy decisions for COVID-19. Whether reported racial inaccuracies in oxygen saturation measured by pulse oximetry are present in patients with COVID-19 and associated with treatment decisions is unknown.ObjectiveTo determine whether there is differential inaccuracy of pulse oximetry by race or ethnicity among patients with COVID-19 and estimate the association of such inaccuracies with time to recognition of eligibility for oxygen threshold-specific COVID-19 therapies.Design, setting, and participantsThis retrospective cohort study of clinical data from 5 referral centers and community hospitals in the Johns Hopkins Health System included patients with COVID-19 who self-identified as Asian, Black, Hispanic, or White.ExposuresConcurrent measurements (within 10 minutes) of oxygen saturation levels in arterial blood (SaO2) and by pulse oximetry (SpO2).Main outcomes and measuresFor patients with concurrent SpO2 and SaO2 measurements, the proportion with occult hypoxemia (SaO2<88% with concurrent SpO2 of 92%-96%) was compared by race and ethnicity, and a covariate-adjusted linear mixed-effects model was produced to estimate the association of race and ethnicity with SpO2 and SaO2 difference. This model was applied to identify a separate sample of patients with predicted SaO2 levels of 94% or less before an SpO2 level of 94% or less or oxygen treatment initiation. Cox proportional hazards models were used to estimate differences by race and ethnicity in time to recognition of eligibility for guideline-recommended COVID-19 therapies, defined as an SpO2 level of 94% or less or oxygen treatment initiation. The median delay among individuals who ultimately had recognition of eligibility was then compared.ResultsOf 7126 patients with COVID-19, 1216 patients (63 Asian [5.2%], 478 Black [39.3%], 215 Hispanic [17.7%], and 460 White [37.8%] individuals; 507 women [41.7%]) had 32 282 concurrently measured SpO2 and SaO2. Occult hypoxemia occurred in 19 Asian (30.2%), 136 Black (28.5%), and 64 non-Black Hispanic (29.8%) patients compared with 79 White patients (17.2%). Compared with White patients, SpO2 overestimated SaO2 by an average of 1.7% among Asian (95% CI, 0.5%-3.0%), 1.2% among Black (95% CI, 0.6%-1.9%), and 1.1% among non-Black Hispanic patients (95% CI, 0.3%-1.9%). Separately, among 1903 patients with predicted SaO2 levels of 94% or less before an SpO2 level of 94% or less or oxygen treatment initiation, compared with White patients, Black patients had a 29% lower hazard (hazard ratio, 0.71; 95% CI, 0.63-0.80), and non-Black Hispanic patients had a 23% lower hazard (hazard ratio, 0.77; 95% CI, 0.66-0.89) of treatment eligibility recognition. A total of 451 patients (23.7%) never had their treatment eligibility recognized, most of whom (247 [54.8%]) were Black. Among the remaining 1452 (76.3%) who had eventual recognition of treatment eligibility, Black patients had a median delay of 1.0 hour (95% CI, 0.23-1.9 hours; P = .01) longer than White patients. There was no significant median difference in delay between individuals of other racial and ethnic minority groups and White patients.Conclusions and relevanceThe results of this cohort study suggest that racial and ethnic biases in pulse oximetry accuracy were associated with greater occult hypoxemia in Asian, Black, and non-Black Hispanic patients with COVID-19, which was associated with significantly delayed or unrecognized eligibility for COVID-19 therapies among Black and Hispanic patients. This disparity may contribute to worse outcomes among Black and Hispanic patients with COVID-19.

Project description:BackgroundStudies using local samples suggest that racial minorities anticipate a greater preference for life-sustaining treatment when faced with a terminal illness. These studies are limited by size, representation, and insufficient exploration of sociocultural covariables.ObjectiveTo explore racial and ethnic differences in concerns and preferences for medical treatment at the end of life in a national sample, adjusting for sociocultural covariables.DesignDual-language (English/Spanish), mixed-mode (telephone/mail) survey.ParticipantsA total of 2,847 of 4,610 eligible community-dwelling Medicare beneficiaries age 65 or older on July 1, 2003 (62% response).MeasurementsDemographics, education, financial strain, health status, social networks, perceptions of health-care access, quality, and the effectiveness of mechanical ventilation (MV), and concerns and preferences for medical care in the event the respondent had a serious illness and less than 1 year to live.ResultsRespondents included 85% non-Hispanic whites, 4.6% Hispanics, 6.3% blacks, and 4.2% "other" race/ethnicity. More blacks (18%) and Hispanics (15%) than whites (8%) want to die in the hospital; more blacks (28%) and Hispanics (21.2%) than whites (15%) want life-prolonging drugs that make them feel worse all the time; fewer blacks (49%) and Hispanics (57%) than whites (74%) want potentially life-shortening palliative drugs, and more blacks (24%, 36%) and Hispanics (22%, 29%) than whites (13%, 21%) want MV for life extension of 1 week or 1 month, respectively. In multivariable analyses, sociodemographic variables, preference for specialists, and an overly optimistic belief in the effectiveness of MV explained some of the greater preferences for life-sustaining drugs and mechanical ventilation among non-whites. Black race remained an independent predictor of concern about receiving too much treatment [adjusted OR = 2.0 (1.5-2.7)], preference for dying in a hospital [AOR = 2.3 (1.6-3.2)], receiving life-prolonging drugs [1.9 (1.4-2.6)], MV for 1 week [2.3 (1.6-3.3)] or 1 month's [2.1 (1.6-2.9)] life extension, and a preference not to take potentially life-shortening palliative drugs [0.4 (0.3-0.5)]. Hispanic ethnicity remained an independent predictor of preference for dying in the hospital [2.2 (1.3-4.0)] and against potentially life-shortening palliative drugs [0.5 (0.3-0.7)].ConclusionsGreater preference for intensive treatment near the end of life among minority elders is not explained fully by confounding sociocultural variables. Still, most Medicare beneficiaries in all race/ethnic groups prefer not to die in the hospital, to receive life-prolonging drugs that make them feel worse all the time, or to receive MV.
