Racial and ethnic disparities in access to physicians with HIV-related expertise

Association of Race and Ethnicity With Initial Prescription of Antiretroviral Therapy Among People With HIV in the US

Importance

Integrase strand transfer inhibitor (INSTI)-containing antiretroviral therapy (ART) is currently the guideline-recommended first-line treatment for HIV. Delayed prescription of INSTI-containing ART may amplify differences and inequities in health outcomes.

Objectives

To estimate racial and ethnic differences in the prescription of INSTI-containing ART among adults newly entering HIV care in the US and to examine variation in these differences over time in relation to changes in treatment guidelines.

Design, Setting, and Participants

Retrospective observational study of 42 841 adults entering HIV care from October 12, 2007, when the first INSTI was approved by the US Food and Drug Administration, to April 30, 2019, at more than 200 clinical sites contributing to the North American AIDS Cohort Collaboration on Research and Design.

Exposures

Combined race and ethnicity as reported in patient medical records.

Main Outcomes and Measures

Probability of initial prescription of ART within 1 month of care entry and probability of being prescribed INSTI-containing ART. Differences among non-Hispanic Black and Hispanic patients compared with non-Hispanic White patients were estimated by calendar year and time period in relation to changes in national guidelines on the timing of treatment initiation and recommended initial treatment regimens.

Results

Of 41 263 patients with information on race and ethnicity, 19 378 (47%) as non-Hispanic Black, 6798 (16%) identified as Hispanic, and 13 539 (33%) as non-Hispanic White; 36 394 patients (85%) were male, and the median age was 42 years (IQR, 30 to 51). From 2007-2015, when guidelines recommended treatment initiation based on CD4+ cell count, the probability of ART initiation within 1 month of care entry was 45% among White patients, 45% among Black patients (difference, 0% [95% CI, -1% to 1%]), and 51% among Hispanic patients (difference, 5% [95% CI, 4% to 7%]). From 2016-2019, when guidelines strongly recommended treating all patients regardless of CD4+ cell count, this probability increased to 66% among White patients, 68% among Black patients (difference, 2% [95% CI, -1% to 5%]), and 71% among Hispanic patients (difference, 5% [95% CI, 1% to 9%]). INSTIs were prescribed to 22% of White patients and only 17% of Black patients (difference, -5% [95% CI, -7% to -4%]) and 17% of Hispanic patients (difference, -5% [95% CI, -7% to -3%]) from 2009-2014, when INSTIs were approved as initial therapy but were not yet guideline recommended. Significant differences persisted for Black patients (difference, -6% [95% CI, -8% to -4%]) but not for Hispanic patients (difference, -1% [95% CI, -4% to 2%]) compared with White patients from 2014-2017, when INSTI-containing ART was a guideline-recommended option for initial therapy; differences by race and ethnicity were not statistically significant from 2017-2019, when INSTI-containing ART was the single recommended initial therapy for most people with HIV.

Conclusions and Relevance

Among adults entering HIV care within a large US research consortium from 2007-2019, the 1-month probability of ART prescription was not significantly different across most races and ethnicities, although Black and Hispanic patients were significantly less likely than White patients to receive INSTI-containing ART in earlier time periods but not after INSTIs became guideline-recommended initial therapy for most people with HIV. Additional research is needed to understand the underlying racial and ethnic differences and whether the differences in prescribing were associated with clinical outcomes.

Brief Report: Physician Reimbursement and Retention in HIV Care: Racial Disparities in the US South

BACKGROUND

Retention in HIV care remains a national challenge. Addressing structural barriers to care may improve retention. We examined the association between physician reimbursement and retention in HIV care, including racial differences.

METHODS

We integrated person-level administrative claims (Medicaid Analytic eXtract, 2008-2012), state Medicaid-to-Medicare physician fee ratios (Urban Institute, 2008, 2012), and county characteristics for 15 Southern states plus District of Columbia. The fee ratio is a standardized measure of physician reimbursement capturing Medicaid relative to Medicare physician reimbursement across states. Generalized estimating equations assessed the association between the fee ratio and retention (≥2 care markers ≥90 days apart in a calendar year). Stratified analyses assessed racial differences. We varied definitions of retention, subsamples, and definitions of the fee ratio, including the fee ratio at parity.

RESULTS

The sample included 55,237 adult Medicaid enrollees with HIV (179,002 enrollee years). Enrollees were retained in HIV care for 76.6% of their enrollment years, with retention lower among non-Hispanic Black (76.1%) versus non-Hispanic White enrollees (81.3%, P < 0.001). A 10-percentage point increase in physician reimbursement was associated with 4% increased odds of retention (adjusted odds ratio 1.04, 95% confidence interval: 1.01 to 1.07). In stratified analyses, the positive, significant association occurred among non-Hispanic Black (1.08, 1.05-1.12) but not non-Hispanic White enrollees (0.87, 0.74-1.02). Findings were robust across sensitivity analyses. When the fee ratio reached parity, predicted retention increased significantly overall and for non-Hispanic Black enrollees.

CONCLUSION

Higher physician reimbursement may improve retention in HIV care, particularly among non-Hispanic Black individuals, and could be a mechanism to promote health equity.

Differences in ambulatory care fragmentation by race

BACKGROUND

More fragmented ambulatory care (i.e., care spread across many providers without a dominant provider) has been associated with more subsequent healthcare utilization (such as more tests, procedures, emergency department visits, and hospitalizations) than less fragmented ambulatory care. It is not known if race and socioeconomic status are associated with fragmented ambulatory care.

METHODS

We conducted a longitudinal analysis of data from the REasons for Geographic and Racial Differences in Stroke (REGARDS) study, using the REGARDS baseline visit plus the first year of follow-up. We included participants ≥65 years old, who had linked fee-for-service Medicare claims, and ≥ 4 ambulatory visits in the first year of follow-up. We used Tobit regression to determine the associations between race, annual household income, and educational attainment at baseline and fragmentation score in the subsequent year (as measured with the reversed Bice-Boxerman Index). Covariates included other demographic characteristics, medical conditions, medication use, health behaviors, and psychosocial variables. Additional analyses categorized visits by the type of provider (primary care vs. specialist).

RESULTS

The study participants (N = 6799) had an average age of 73.0 years, 53% were female, and 30% were black. Nearly half had low annual household income (<$35,000) and 41% had a high school education or less. Overall, participants had a median of 10 ambulatory visits to 4 providers in the 12 months following their baseline study visit. Participants in the highest quintile of fragmentation scores had a median of 11 visits to 7 providers. Black race was associated with an absolute adjusted 3% lower fragmentation score compared to white race (95% confidence interval (2% lower to 4% lower; p < 0.001). This difference was explained by blacks seeing fewer specialists than whites. Income and education were not independent predictors of fragmentation scores.

CONCLUSIONS

Among Medicare beneficiaries, blacks had less fragmented ambulatory care than whites, due to lower utilization of specialty care. Future research is needed to determine the effect of fragmented care on health outcomes for blacks and whites.

Viral Pandemics of the Last Four Decades: Pathophysiology, Health Impacts and Perspectives

The twenty-first century has witnessed some of the deadliest viral pandemics with far-reaching consequences. These include the Human Immunodeficiency Virus (HIV) (1981), Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) (2002), Influenza A virus subtype H1N1 (A/H1N1) (2009), Middle East Respiratory Syndrome Coronavirus (MERS-CoV) (2012) and Ebola virus (2013) and the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) (2019-present). Age- and gender-based characterizations suggest that SARS-CoV-2 resembles SARS-CoV and MERS-CoV with regard tohigher fatality rates in males, and in the older population with comorbidities. The invasion-mechanism of SARS-CoV-2 and SARS-CoV, involves binding of its spike protein with angiotensin-converting enzyme 2 (ACE2) receptors; MERS-CoV utilizes dipeptidyl peptidase 4 (DPP4), whereas H1N1 influenza is equipped with hemagglutinin protein. The viral infections-mediated immunomodulation, and progressive inflammatory state may affect the functions of several other organs. Although no effective commercial vaccine is available for any of the viruses, those against SARS-CoV-2 are being developed at an unprecedented speed. Until now, only Pfizer/BioNTech's vaccine has received temporary authorization from the UK Medicines and Healthcare products Regulatory Agency. Given the frequent emergence of viral pandemics in the 21st century, proper understanding of their characteristics and modes of action are essential to address the immediate and long-term health consequences.

Structural Determinants of Antiretroviral Therapy Use, HIV Care Attendance, and Viral Suppression among Adolescents and Young Adults Living with HIV

BACKGROUND

The authors examined associations between structural characteristics and HIV disease management among a geographically diverse sample of behaviorally and perinatally HIV-infected adolescents and young adults in the United States.

METHODS

The sample included 1891 adolescents and young adults living with HIV (27.8% perinatally infected; 72.2% behaviorally infected) who were linked to care through 20 Adolescent Medicine Trials Network for HIV/AIDS Interventions Units. All completed audio computer-assisted self-interview surveys. Chart abstraction or blood draw provided viral load data. Geographic-level variables were extracted from the United States Census Bureau (e.g., socioeconomic disadvantage, percent of Black and Latino households, percent rural) and Esri Crime (e.g., global crime index) databases as Zip Code Tabulation Areas. AIDSVu data (e.g., prevalence of HIV among youth) were extracted at the county-level. Using HLM v.7, the authors conducted means-as-outcomes random effects multi-level models to examine the association between structural-level and individual-level factors and (1) being on antiretroviral therapy (ART) currently; (2) being on ART for at least 6 months; (3) missed HIV care appointments (not having missed any vs. having missed one or more appointments) over the past 12 months; and (4) viral suppression (defined by the corresponding assay cutoff for the lower limit of viral load at each participating site which denoted nondetectability vs. detectability).

RESULTS

Frequencies for the 4 primary outcomes were as follows: current ART use (n = 1120, 59.23%); ART use for ≥6 months (n = 861, 45.53%); at least one missed HIV care appointment (n = 936, 49.50); and viral suppression (n = 577, 30.51%). After adjusting for individual-level factors, youth living in more disadvantaged areas (defined by a composite score derived from 2010 Census indicators including percent poverty, percent receiving public assistance, percent of female, single-headed households, percent unemployment, and percent of people with less than a high school degree) were less likely to report current ART use (OR: 0.85, 95% CI: 0.72-1.00, p = .05). Among current ART users, living in more disadvantaged areas was associated with greater likelihood of having used ART for ≥6 months. Participants living in counties with greater HIV prevalence among 13-24 year olds were more likely to report current ART use (OR: 1.32, 95% CI: 1.05-1.65, p = .02), ≥6 months ART use (OR: 1.32, 95% CI: 1.05-1.65, p = .02), and to be virally suppressed (OR: 1.50, 95% CI: 1.20-1.87, p = .001); however, youth in these areas were also more likely to report missed medical appointments (OR: 1.32, 95% CI: 1.07-1.63, p = .008).

CONCLUSIONS

The findings underscore the multi-level and structural factors associated with ART use, missed HIV care appointments, and viral suppression for adolescents and young adults in the United States. Consideration of these factors is strongly recommended in future intervention, clinical practice, and policy research that seek to understand the contextual influences on individuals' health behaviors.

Disparities in CD4+ T-Lymphocyte Monitoring Among Human Immunodeficiency Virus-Positive Medicaid Beneficiaries: Evidence of Differential Treatment at the Point of Care

BACKGROUND

Monitoring of immune function, measured by CD4 cell count, is an essential service for people with Human Immunodeficiency Virus (HIV). Prescription of antiretroviral (ARV) medications is contingent on CD4 cell count; patients without regular CD4 monitoring are unlikely to receive ARVs when indicated. This study assesses disparities in CD4 monitoring among HIV-positive Medicaid beneficiaries.

METHODS

In this retrospective observational study, we examined 24 months of administrative data on 2,250 HIV-positive, continuously-enrolled fee-for-service Medicaid beneficiaries with at least two outpatient healthcare encounters. We used logistic regression to evaluate the association of patient demographics (age, gender, race/ethnicity, and language) with receipt of at least one CD4 test per year, controlling for other potentially confounding variables.

RESULTS

Having a history of ARV therapy was positively associated with receipt of CD4 tests. We found racial/ethnic, gender, and age disparities in CD4 testing. Among individuals with a history of ARV use, all racial/ethnic groups were significantly less likely to have CD4 tests than White non-Latinos (African Americans, OR = 0.35, p<0.0001; Asian/Pacific Islanders, OR = 0.31, p=0.0047; and, Latinos, OR = 0.42, p<0.0001).

CONCLUSIONS

Disparities in receipt of CD4 tests elucidate one potential pathway for previously reported disparities in ARV treatment. Further qualitative and quantitative research is needed to identify the specific factors that account for these disparities, so that appropriate interventions can be implemented.

Race, Relationships and Trust in Providers among Black Patients with HIV/AIDS

A trustful patient-provider relationship is a strong predictor of positive outcomes, including treatment adherence and viral suppression, among patients with HIV/AIDS. Understanding factors that inform this relationship is especially relevant for Black patients, who bear a disproportionate burden of HIV morbidity and mortality, and may face challenges associated with seeing providers of a racial/ethnic background that is different from their own. Using data collected through the Enhancing Communication and HIV Outcomes (ECHO) study, we build upon extant research by examining patient and provider characteristics that may influence Black patients' trust in their provider. ECHO data were collected from four ambulatory care sites in Baltimore, Detroit, New York and Portland, Oregon (N=435). Regression analysis results indicate that trust in health care institutions and cultural similarity between patient and provider are strongly associated with patients' trust in their provider. Lower perceived social status, being currently employed, and having an older provider were also related to greater patient-provide trust. These findings can inform interventions to improve trust and reduce disparities in HIV care and outcomes that stem from mistrust among Black patients.

Liver transplantation trends in the HIV population

There is a paucity of information on the utilization patterns of liver transplantation (LT) for HIV-positive individuals. The aim of this study is to examine the trends in LT of HIV patients in the US. This study was a retrospective analysis using the UNOS database (1999-2008). There were 135 HIV-positive patients. There was a steady increase in the number of LT recipients over time as well as regional variation. Ethnic minorities accounted for 33.3% and there was no ethnic difference in survival. Though LT for HIV-positive patients is on the rise, significant variations exist in patient demographics, geographic location, and insurance payer.

Recent trends in hospital utilization and mortality for HIV infection: 2000-2005

OBJECTIVE

Ethnic minority populations have been disproportionately affected by the HIV disease. The objective of this report was to assess the prevalence and trend of HIV-related hospitalization and mortality in Florida in 2000 through 2005 by 6 sex- race/ethnic groups.

METHODS

Using data from the Florida Agency for Health Care Administration from 2000 through 2005, discharge records with primary or secondary diagnosis of HIV infection were included, and chi2 and Cochran-Armitage tests and multiple regression models were used in analyses.

RESULTS

Of all HIV-related hospitalizations (N = 159695), about 56%, 28%, and 12% of records belonged to blacks, whites, and Hispanics, respectively. The average proportions of HIV hospitalization during the period of 2000-2005 were approximately 29% (black male), 27% (black female), 22% (white male), 9% (Hispanic male), 6% (white female), and 3% (Hispanic female) (all p < .01). The frequencies of death were the highest among black males followed by black females, white males, Hispanic males, white females, and Hispanic females.

CONCLUSION

Sex-racial/ethnic disparities are evident in the HIV-related hospital utilizations and deaths. Further research is needed to understand the reasons for the disparities among hospitalized patients to reduce both health and economic consequences associated with HIV disease in Florida.

The four Cs of HIV prevention with African Americans: crisis, condoms, culture, and community

HIV/AIDS continues to be a devastating epidemic with African American communities carrying the brunt of the impact. Despite extensive biobehavioral research, current strategies have not resulted in significantly decreasing HIV/AIDS cases among African Americans. The next generation of HIV prevention and risk reduction interventions must move beyond basic sex education and condom use and availability. Successful interventions targeting African Americans must optimize strategies that integrate socio-cultural factors and address institutional and historical barriers that hinder or support HIV risk reduction behaviors. Community-based participatory research to decrease the HIV/AIDS disparity by building community capacity and infrastructure and advocating for and distributing equitably, power and resources, must be promoted. Recommendations for paradigm shifts in using innovative theories and conceptual frameworks and for training researchers, clinicians, grant and journal reviewers, and community members are made so that culturally congruent interventions may be tested and implemented at the community level.

"Leaving the comfort of the familiar": fostering workplace cultural awareness through short-term global experiences

PROBLEM

Facilitating the development of student nurses' cultural competence and translating these experiences into the clinical setting.

METHODS

Qualitative methods.

FINDINGS

A short-term global immersion experience informs student nurses' cultural awareness, education, and future clinical practice.

CONCLUSIONS

Participation in a short-term global health experience contributes to students' personal growth and broadens their insight into multicultural care.

Looking forward, looking back: assessing variations in hospital resource use and outcomes for elderly patients with heart failure

BACKGROUND

Recent studies have found substantial variation in hospital resource use by expired Medicare beneficiaries with chronic illnesses. By analyzing only expired patients, these studies cannot identify differences across hospitals in health outcomes like mortality. This study examines the association between mortality and resource use at the hospital level, when all Medicare beneficiaries hospitalized for heart failure are examined.

METHODS AND RESULTS

A total of 3999 individuals hospitalized with a principal diagnosis of heart failure at 6 California teaching hospitals between January 1, 2001, and June 30, 2005, were analyzed with multivariate risk-adjustment models for total hospital days, total hospital direct costs, and mortality within 180-days after initial admission ("Looking Forward"). A subset of 1639 individuals who died during the study period were analyzed with multivariate risk-adjustment models for total hospital days and total hospital direct costs within 180-days before death ("Looking Back"). "Looking Forward" risk-adjusted hospital means ranged from 17.0% to 26.0% for mortality, 7.8 to 14.9 days for total hospital days, and 0.66 to 1.30 times the mean value for indexed total direct costs. Spearman rank correlation coefficients were -0.68 between mortality and hospital days, and -0.93 between mortality and indexed total direct costs. "Looking Back" risk-adjusted hospital means ranged from 9.1 to 21.7 days for total hospital days and 0.91 to 1.79 times the mean value for indexed total direct costs. Variation in resource use site ranks between expired and all individuals were attributable to insignificant differences.

CONCLUSIONS

California teaching hospitals that used more resources caring for patients hospitalized for heart failure had lower mortality rates. Focusing only on expired individuals may overlook mortality variation as well as associations between greater resource use and lower mortality. Reporting values without identifying significant differences may result in incorrect assumption of true differences.

African-American clinicians providing HIV care: the experience of the National HIV/AIDS Clinicians' Consultation Center

This analysis compares patient and provider characteristics of African-American clinicians and non-African-American clinicians who called the National HIV Telephone Consultation Service (Warmline). In 2004, a total of 2,077 consultations were provided for 1,020 clinicians, 70 (6.9%) of whom were African American. Compared to the non-African-American group, a higher percentage of African-American clinicians were nurses (20.0% vs. 8.8%, p=0.002). A significantly lower percentage of African-American physicians were infectious disease specialists (3.5% vs. 25.6%, p=0.007). African-American clinicians were more likely to work in a community clinic (48.5% vs. 34.1%, p=0.015). Both African-American and non-African American clinicians reported caring for a similar number of HIV-infected patients. Patient-provider racial concordance was common among African-American clinicians (76.4%), whereas non-African-American clinicians called about patients of more diverse racial and ethnic backgrounds. African-American clinicians who called Warmline exhibited differences in patient and provider characteristics when compared to all other clinicians. These findings contribute to the growing body of research on HIV providers in the United States.

Ethnicity, race, and gender. Differences in serious adverse events among participants in an antiretroviral initiation trial: results of CPCRA 058 (FIRST Study)

BACKGROUND

Differences in adverse events by gender and race/ethnicity have not been described extensively in randomized clinical trials of HIV antiretroviral therapy (ART).

METHODS

Antiretroviral-naive HIV-infected participants enrolled in a long-term randomized clinical trial of 3 different initial ART strategies -- protease inhibitor (PI), nonnucleoside reverse transcriptase inhibitor (NNRTI), or PI plus NNRTI-based combinations -- with a median follow-up of 5 years, were compared by gender and race for 14 categories of grade 4 adverse events, discontinuation of initial antiretroviral regimen, and all-cause mortality. Multivariate analysis was used to identify predictors of events and death.

RESULTS

Among 1301 participants with complete data, there were 701 blacks, 225 Latinos, and 263 women. Several baseline characteristics differed by gender and race, including age, HIV transmission risk, hepatitis B or C coinfection, viral load, diagnosis of AIDS, body mass index, and baseline hypertension. Grade 4 events occurred in 409 participants (rate: 8.9/100 person-years). There were 176 deaths (rate: 3.0/100 person-years) and 523 discontinuations of regimen for any toxicity (rate: 13/100 person-years). In the fully adjusted regressions, blacks had greater risk for cardiovascular (hazard ratio [HR] = 2.64, 95% confidence interval [CI]: 1.04 to 6.67) and renal (HR = 3.83, 95% CI: 1.28 to 11.5) events. Black men had more psychiatric events (HR = 2.45, 95% CI: 1.13 to 5.30). Women had a higher risk for anemia (HR = 2.34, 95% CI: 1.09 to 4.99).

CONCLUSION

Among HIV-infected participants initiating ART, there were significant risk-adjusted differences for specific adverse events by gender and race but not in the overall adverse event rates, all-cause mortality, or rates of toxicity-related treatment discontinuations.

HIV System Navigation: an emerging model to improve HIV care access

Little is known about the effectiveness of outreach interventions to engage and retain underserved populations living with HIV in stable, primary medical care. This study provided an opportunity to adapt a patient navigation model first developed for cancer care to assess its effectiveness with HIV-infected disadvantaged populations. Four grantees from the Health Resources and Services Administration (HRSA)-funded Outreach Initiative developed and successfully implemented navigation-like interventions. We examined the effectiveness of these interventions in decreasing barriers to HIV primary medical care and improving health outcomes. The conceptual framework laid out in the 1993 Institute of Medicine report Access to Health Care in America provided a valuable heuristic for guiding the analysis, and we used the model to select measures for the study. A reduction in barriers, improvement in mediators, and improved health outcomes were observed over the 12-month intervention period. Structural barriers to HIV care and provider engagement were significantly associated with health outcomes. Based on study results, we propose that an adapted navigation approach referred to as "HIV System Navigation" has promise for improving access to HIV care and warrants further development.

Cultural competence in health care and its implications for pharmacy. Part 1. Overview of key concepts in multicultural health care

Pharmacists are caring for more individuals of diverse age, gender, race, ethnicity, socioeconomic status, religion, sexual orientation, and health beliefs than in previous decades. Not all residents of the United States equally experience long life spans and good health. Health disparities in various cultures have been documented. One critical aspect of reducing health disparities is moving health care providers, staff, administrators, and practices toward increased cultural competence and proficiency. Effective delivery of culturally and linguistically appropriate service in cross-cultural settings is identified as cultural competence. Culture is a dynamic process, with people moving in and out of various cultures throughout their lives. The failure to understand and respect individuals and their cultures could impede pharmaceutical care. Incongruent beliefs and expectations between the patient and pharmacist could lead to misunderstandings, confusion, and ultimately to drug misadventures. Models and frameworks have been developed that provide descriptions of the process by which individuals, practice settings, and organizations can become culturally competent and proficient. This article, the first in a five-part series, presents an overview of issues related to cultural competence in health care with an emphasis on the pharmacy profession. Also provided are definitions for cultural competence and related terms, a brief overview of health disparities and challenges to the common morality, and a discussion of models and frameworks that describe pathways to cultural competence and proficiency.

Attitudes and perceptions of AIDS clinical trials group site coordinators on HIV clinical trial recruitment and retention: a descriptive study

HIV-seropositive blacks, Hispanics, women of all ethnicities, and injection drug users (IDUs) have low rates of clinical trial participation. The opinions of research nurses and study coordinators as potential facilitators and barriers to access to clinical trials may contribute to this disparity. Study coordinators and research nurses from the adult AIDS Clinical Trials Group (ACTG) clinical trials units responded to an anonymous computer-based survey comprising multiple choice questions and clinical scenarios. Descriptive statistics were used to determine frequencies of responses. Recruitment rates of blacks, Hispanics, women and IDUs were mostly rated appropriate compared with the geographic region demographics. Most sites ranked white men as being the most interested in clinical trials. Sites rated their most effective interactions were with white men. Respondents felt they were less likely to enroll individuals who had missed previous clinical appointments or did not speak English. Perceptions that IDUs, Hispanics, blacks, and, to a lesser extent, women had less interest in clinical trials participation than white males may affect recruitment of the targeted populations. Interventions to improve interactions with targeted populations and to remove logistical and language barriers may improve the diversity of clinical trial participants.
