Little is known about longitudinal change in physical functioning of older African American/Black and White HIV-infected persons. We examined up to 10 years of data on African American ( N  = 1,157) and White ( N  = 400) men with HIV infection and comparable HIV-negative men ( n  = 1,137 and 530, respectively), age 50-91 years from the Veterans Aging Cohort Study Survey sample. Physical functioning was assessed using the SF-12 (12-Item Short Form Health Survey) physical component summary (PCS) score. Mixed-effects models examined association of demographics, health conditions, health behaviors, and selected interactions with PCS score; HIV biomarkers were evaluated for HIV-infected persons. PCS scores were approximately one standard deviation below that of the general U.S. population of similar age. Across the four HIV/race groups, over time and through ages 65-75 years, PCS scores were maintained; differences were not clinically significant. PCS score was not associated with race or with interactions among age, race, and HIV status. CD4 and viral load counts of African American and White HIV-infected men were similar. Older age, low socioeconomic status, chronic health conditions and depression, lower body mass index, and smoking were associated with poorer PCS score in both groups. Exercising and, counterintuitively, being HIV infected were associated with better PCS score. Among these older African American and White male veterans, neither race nor HIV status was associated with PCS score, which remained relatively stable over time. Chronic disease, depression, and lack of exercise were associated with lower PCS score. To maintain independence in this population, attention should be paid to controlling chronic conditions, and emphasizing good health behaviors.

Context: Hospices that enroll patients receiving expensive palliative therapies may serve more African Americans because of their greater preferences for aggressive end-of-life care., Objectives: Examine the association between hospices' admission practices and enrollment of African Americans and whites., Methods: This was a cross-sectional study of 61 North and South Carolina hospices. We developed a hospice admission practices scale; higher scores indicate less restrictive practices, that is, greater frequency with which hospices admitted those receiving chemotherapy, inotropes, and so forth. In separate multivariate analyses for each racial group, we examined the relationship between the proportion of decedents (age ≥ 65) served by a hospice in their service area (2008 Medicare Data) and admission practices while controlling for health care resources (e.g., hospital beds) and market concentration in the area, ownership, and budget., Results: Nonprofit hospices and those with larger budgets reported less restrictive admission practices. In bivariate analyses, hospices with less restrictive admission practices served a larger proportion of patients in both racial groups (P < 0.001). However, in the multivariate models, nonprofit ownership and larger budgets but not admission practices predicted the outcome., Conclusion: Hospices with larger budgets served a greater proportion of African Americans and whites in their service area. Although larger hospices reported less restrictive admission practices, they also may have provided other services that may be important to patients regardless of race, such as more in-home support or assistance with nonmedical expenses, and participated in more outreach activities increasing their visibility and referral base. Future research should explore factors that influence decisions about hospice enrollment among racially diverse older adults., (Copyright © 2016 American Academy of Hospice and Palliative Medicine.

Context: Although blacks use hospice at lower rates than whites in the U.S., racial differences in hospice use vary by geographic area., Objectives: To describe intercounty variability in black-white differences in hospice use and the association with the supply of health care resources., Methods: Subjects were a retrospective cohort of Medicare beneficiaries in North and South Carolina who died in 2008. Using Wilcoxon tests and logistic regression, we examined the differences in the supply of health care resources (hospital beds and physicians per population age 65 years and older, percentage of generalists, etc.) between counties with and without racial disparity in hospice use. Counties with a racial disparity had significantly (P < 0.05) higher rates of hospice use among whites than blacks., Results: Of 76,283 decedents in 128 counties, 19.78% were black. In the 39 counties (30.47%) with racial disparity in hospice use, the mean proportion of whites who enrolled in hospice was 41.3% vs. 28.66% of blacks (P < 0.0001). Counties with more hospital beds per population age 65 years and older had a higher odds (OR, 1.39; 95% confidence interval [CI] 1.04-1.86) and those with a larger proportion of generalists had a lower odds (OR, 0.01; 95% CI 0.001-0.476) of having a racial disparity in hospice use., Conclusion: In most counties, the rates of hospice use were similar for blacks and whites. In counties with a racial disparity, there were more resources to deliver aggressive care (i.e., hospital beds and specialists). Because of a greater preference for life-sustaining therapies, blacks may be more likely to use acute care services at the end of life when resources for the delivery of these services are readily available., (Copyright © 2013 U.S. Cancer Pain Relief Committee.

Background: It is unclear whether distinct weight-related trajectory classes, differing in course, demographics, and health characteristics, exist in the elderly population., Methods: Data came from the 10-year (1986-1996) Duke Established Populations for Epidemiologic Studies of the Elderly study of 3,861 black (54%) and white (46%) participants aged 65-105 years. Latent-class trajectories of body mass index (BMI: kg/m(2)) based on self-reported weight and height at baseline, 3, 6, and 10 years later were determined using generalized mixture models. Polytomous logistic regression was used to identify baseline demographic and health characteristics that distinguished the trajectories, and 10-year postbaseline data to confirm the findings., Results: We identified three trajectories: normal weight (BMI ~24, 27.6% of the sample), overweight (BMI ~26, 65.1%), and obese (BMI ~31, 7.3%). Demographic characteristics distinguished the three trajectories: highest odds of blacks, women, and less education in the obese trajectory, lowest in the normal-weight trajectory. Obese and overweight differed adversely from normal-weight trajectories, but not significantly from each other on cognitive impairment, hypertension, and diabetes. Depressive symptomatology was more prevalent in the obese; they were also younger. There was no association with cancer or heart disease., Conclusion: Distinct trajectories and course of BMI were present in this older population. Weight loss increased with increase in BMI class. Although demographic characteristics distinguished all trajectory classes, adverse health characteristics distinguished the overweight and obese classes from the normal-weight class, but not from each other. Problems associated with education and health are present at study entry and should be addressed earlier in life.

African Americans are less likely than Whites to enroll in hospice. In addition, patients are often referred to hospice very close to death, when they may not have time to take advantage of the full range of hospice services. Understanding how race and location before hospice enrollment are related to hospice length of stay (LOS) may inform the development of interventions to increase timely access to hospice care. Using data from a national hospice provider, African Americans and Whites admitted to routine home hospice care in a private residence between January 1, 2000, and December 31, 2003, were identified. Logistic regression was used to examine the association between race and hospice preadmission location (hospital vs other locations) and preadmission location and hospice LOS (≤7 days vs >7 days) after adjusting for demographic and hospice use variables. Of 43,869 enrollees, 15.3% were African American. One to 2 days before hospice enrollment, African Americans were more likely than Whites to be in the hospital than in all other locations (48.6% vs 32.3%, P<.001; adjusted odds ratio=1.83, 95% confidence interval=1.73-1.95). Regardless of race, those whose preadmission location was the hospital were more likely than those from other locations to die 7 days or less after hospice enrollment. Initiatives to improve end-of-life care should focus on increasing timely access to hospice referrals in settings outside of the hospital. Future research should examine whether racial differences in hospice preadmission location reflect differences in preferences for care or disparities in timely access to hospice referrals in non-acute care settings., (© 2011, Copyright the Authors.

Background: To ascertain accuracy of self-reported height, weight (and hence body mass index) in African American and white women and men older than 70 years of age., Method: The sample consisted of cognitively intact participants at the third in-person wave (1992-1993) of the Duke Established Populations for Epidemiologic Studies of the Elderly (age 71 and older, N = 1761; residents of five adjacent counties, one urban, four rural). During in-person, in-home interviews using trained interviewers, height and weight were self-reported (and measured later in the same visit using a standardized protocol), and information were obtained on race, sex, and age., Results: Accuracy of self-reported height and weight was high (intraclass correlation coefficient 0.85 and 0.97, respectively) but differed as a function of race and age. On average, all groups overestimated their height; whereas (non-Hispanic) white men and women underestimated their weight, African Americans overestimated their weight. Overestimation of height and weight was more marked in persons 85 years and older. Specificity for overweight (body mass index [kg/m(2)] ≥ 25) and obesity (body mass index ≥ 30) ranged from 0.90 to 0.99 for African Americans and whites, but sensitivity was better for African Americans (overweight: 0.81, obesity: 0.89), than for whites (0.66 and 0.57, respectively)., Conclusions: Height and weight self-reported by African Americans and whites over the age of 70 can be used in epidemiological studies, with greater caution needed for self-reports of whites, and of persons 85 years of age or older.

Cultural beliefs and values are thought to account for differences between African Americans and whites in the use of advance directives and beliefs about hospice care, but few data clarify which beliefs and values explain these differences. Two hundred five adults aged 65 and older who received primary care in the Duke University Health System were surveyed. The survey included five scales: Hospice Beliefs and Attitudes, Preferences for Care, Spirituality, Healthcare System Distrust, and Beliefs About Dying and Advance Care Planning. African Americans were less likely than white subjects to have completed an advance directive (35.5% vs 67.4%, P<.001) and had less favorable beliefs about hospice care (Hospice Beliefs and Attitudes Scale score, P<.001). African Americans were more likely to express discomfort discussing death, want aggressive care at the end of life, have spiritual beliefs that conflict with the goals of palliative care, and distrust the healthcare system. In multivariate analyses, none of these factors alone completely explained racial differences in possession of an advance directive or beliefs about hospice care, but when all of these factors were combined, race was no longer a significant predictor of either of the two outcomes. These findings suggest that ethnicity is a marker of common cultural beliefs and values that, in combination, influence decision-making at the end of life. This study has implications for the design of healthcare delivery models and programs that provide culturally sensitive end-of-life care to a growing population of ethnically diverse older adults.

Background: Hospice provides supportive care to terminally ill patients at the end of life. However, some enrollees leave hospice before death in search of therapies that may prolong survival. Because of a greater preference for life-sustaining therapies at the end of life, African American patients may be more likely than white patients to withdraw from hospice to seek life-prolonging therapies., Methods: In a secondary data analysis of African American and white patients discharged from VITAS hospice programs between January 1, 1999, and December 31, 2003, we used logistic regression to examine the association between race and discharge disposition defined as hospice revocation to pursue aggressive care (eg, emergency medical care, chemotherapy, or invasive medical intervention) vs all other discharges. We used a Cox proportional hazards model to examine survival at 1 year after hospice revocation in a subgroup of enrollees from Florida hospice programs., Results: Of the 166 197 enrollees, 2.8% revoked hospice to pursue aggressive care, and African American patients were more likely than white patients to do so (4.5% vs 2.5%; P< .001). In multivariate analysis, African American patients had a 70% higher odds of leaving hospice to pursue life-prolonging therapies (odds ratio, 1.70; 95% confidence interval, 1.57-1.84). In the subgroup analysis, 48.4% of the enrollees who revoked hospice to pursue life-prolonging therapies were still alive at 1 year., Conclusions: African American patients were more likely than white patients to revoke hospice to pursue life-prolonging therapies. Models of health care that couple curative and palliative therapies may be more attractive to African American patients and more effective at maximizing continuity throughout life-limiting illness.

Patients with noncancer life-limiting illnesses now represent over half of all hospice enrollees, compared to only one-quarter of enrollees in 1992. Whether this growth in enrollees with noncancer diagnoses has been similar for Caucasians and African Americans, a group historically underrepresented in hospice, has not been described. The purpose of this study was to compare rates of noncancer diagnoses among African American and Caucasian hospice enrollees. We analyzed data from the administrative database of VITAS Healthcare Corporation, including all African Americans and Caucasians discharged from hospice between January 1, 1999 and December 31, 2003. Of the 166,390 eligible discharges, 14.6% were African American, and 85.4% were Caucasian. Over the five-year study period, there was a similar increase in the crude proportion of enrollees with noncancer diagnoses in both groups, from 42% to 49.7% among African Americans and 57.9% to 64.3% among Caucasians. However, in multivariate analysis (adjusted for age, gender, admission level of care, payment source, Health Maintenance Organization (HMO) use, discharge year, and hospice program characteristics-size, location, presence of an inpatient unit), African Americans had 32% lower odds of having a noncancer (vs. cancer) diagnosis than Caucasians (odds ratio [OR] 0.68 [0.66, 0.77]). While numerous studies document lower rates of hospice use among African Americans than Caucasians, these findings suggest disease-specific differences in patterns of hospice use, with greater disparities in hospice use among African Americans with noncancer diagnoses than those with cancer diagnoses. Targeted efforts to increase hospice use among African Americans with noncancer diagnoses may be important in reducing racial disparities in overall hospice use and improving the quality of care for dying African Americans.

Despite disparities in health care access and quality, African Americans are underrepresented in many areas of clinical investigation, including research in end-of-life care. Because of the importance of surrogate reports in assessing the quality of end-of-life care, this study examined racial differences in next-of-kin participation in an ongoing study of satisfaction with end-of-life care. The parent study includes after-death interviews with next-of-kin of elderly African Americans and Caucasians who died at Duke Hospital. This analysis included next-of-kin of elders who died at Duke Hospital from December 1, 2003 to December 31, 2004. During this period, there were 471 decedents whose next-of-kin were eligible for participation. Of these, 133 (28%) were African American and 338 (72%) were Caucasian. There were no racial differences in completion, contact, or overall response rates. Of those contacted, 39.8% of African Americans and 37.8% of Caucasians completed the study. In multivariate analysis, only the relationship of the next-of-kin to the decedent was an independent predictor of study completion. Children of decedents were significantly more likely to participate than spouses (odds ratio [OR] 2.1 [1.14, 3.86]). In this analysis, next-of-kin of African American and Caucasian decedents were equally likely to participate in an after-death interview assessing satisfaction with end-of-life care. The use of racially concordant interviewers, subject identification with the institution, and the absence of socioeconomic constraints may partly explain these findings. Given the growing diversity of the U.S. population, researchers in end-of-life care must use strategies aimed at recruiting racially and ethnically diverse samples.

Purpose: To explore the impact of varying hemoglobin levels on mortality, function, and cognition in a representative population of older persons., Methods: Participants in this prospective cohort study included 1 744 men and women, aged 71 years or older, from a random household sample living in Durham and surrounding counties in North Carolina. Hemoglobin levels were obtained from participants at baseline in 1992. Functional status was measured at the 4-year follow-up interview using Katz and instrumental activities of daily living. Cognition was measured using the Short Portable Mental Status Questionnaire (SPMSQ). Death was determined by search of the National Death Index, and all deaths through 2000 are included., Results: Using World Health Organization (WHO) criteria, the prevalence of anemia was 24%. There was a strong racial difference with an odds ratio, adjusted for age, education, estimated glomerular filtration rate and comorbidity of 3.0 (95% CI, 2.3-3.9) in African Americans compared with Caucasians. The risk ratio for 8-year mortality was 1.7 (95% CI, 1.5-2.0) for anemic subjects (P = .0001) and did not differ by sex or race. Anemia was strongly associated with poorer physical function (P = .0001) and cognitive function (P = .0001), and predicted decreases in both over a 4-year period., Conclusions: In an elderly community-based population, anemia is more prevalent in African Americans and is independently associated with increased mortality over 8 years for both races and sexes. Anemia also is a risk factor for functional and cognitive decrease.

Purpose: The aim of this study was to ascertain whether the determinants of death differ as a function of type of analysis in a representative sample of older African American and White people with comparable mortality rates., Design and Methods: Participants included all African American (n = 2,261) and White (n = 1,875) people at the Duke site of the Established Populations for Epidemiological Studies of the Elderly. Baseline information used to predict mortality 12 years later included demographic, health, and functional characteristics. Mortality (55% for African American people and 54% for White people) was determined through the National Death Index. Cox proportional hazards models, logistic regression, and tree-based classification analysis were used (separately for African American and White people) to identify risk factors for mortality., Results: Risk factors for mortality were comparable, but the constellation of characteristics indicating higher risk for death differed between African American and White people., Implications: Proportional hazards and logistic regression identified risk factors in general; tree-based classification models identified the characteristics of groups at risk. The analysis used may influence the type and manner of intervention.
