"Advocates for Each Other": The creation and evaluation of a pragmatic peer navigation program for black patients in primary care with uncontrolled hypertension

BACKGROUND

Black individuals in the U.S. and in our primary care clinic experience worse control of blood pressure compared to White individuals.

OBJECTIVE

To address this inequity, our objectives were to (1) elicit from patients and community members their ideas for barriers and facilitators to blood pressure control; and (2) use their input to design and pilot a navigator program for Black patients in our clinic to improve blood pressure management.

PATIENT INVOLVEMENT

We conducted three focus groups with 27 individuals and identified two main areas of need that informed the peer navigator program: (1) community-based services and (2) skill development for hypertension self-management.

METHODS

Peer navigators from the Black community called participants at least monthly for 6-12 months and connected them with medical and social services. Available blood pressure data was used as the primary outcome to measure change pre- to post-peer navigation program.

RESULTS

Among 499 eligible patients in the clinic, 53 (10.6%) enrolled in the peer navigation program. For those with baseline and follow-up blood pressure data, mean systolic blood pressure decreased from 155.9 to 142.4 mmHg after the program (change of -13.6, 95% CI -24.7 to -2.4) for the enrolled patients (N = 17) and from 139.1 to 137.1 mmHg (change of -2.5, -4.8 to 1.9) for unenrolled, comparison patients (N = 183).

DISCUSSION

This community-informed peer navigation program to support Black patients with uncontrolled hypertension led to a 11.1 mmHg greater decrease in average systolic blood pressure for enrolled patients compared to the comparison group. However, the enrolled group started with a significantly higher systolic blood pressure at baseline with more room for improvement. While this study was conducted during the pandemic years, low uptake of this program needs to be addressed in expansion efforts.

PRACTICAL VALUE

Clinic-based peer navigation for hypertension improved blood pressure control and was highly regarded by the subset of enrolled patients. Increasing uptake and sustainable funding for non-billable clinic roles remain areas of need.

Investigation of the role of perceived access to primary care in mediating and moderating racial and ethnic disparities in chronic disease control in the veterans health administration

OBJECTIVE

To examine the role of patient-perceived access to primary care in mediating and moderating racial and ethnic disparities in hypertension control and diabetes control among Veterans Health Administration (VA) users.

DATA SOURCE AND STUDY SETTING

We performed a secondary analysis of national VA user administrative data for fiscal years 2016-2019.

STUDY DESIGN

Our primary exposure was race or ethnicity and primary outcomes were binary indicators of hypertension control (<140/90 mmHg) and diabetes control (HgbA1c < 9%) among patients with known disease. We used the inverse odds-weighting method to test for mediation and logistic regression with race and ethnicity-by-perceived access interaction product terms to test moderation. All models were adjusted for age, sex, socioeconomic status, rurality, education, self-rated physical and mental health, and comorbidities.

DATA COLLECTION/EXTRACTION METHODS

We included VA users with hypertension and diabetes control data from the External Peer Review Program who had contemporaneously completed the Survey of Healthcare Experience of Patients-Patient-Centered Medical Home. Hypertension (34,233 patients) and diabetes (23,039 patients) samples were analyzed separately.

PRINCIPAL FINDINGS

After adjustment, Black patients had significantly lower rates of hypertension control than White patients (75.5% vs. 78.8%, p < 0.01); both Black (81.8%) and Hispanic (80.4%) patients had significantly lower rates of diabetes control than White patients (85.9%, p < 0.01 for both differences). Perceived access was lower among Black, Multi-Race and Native Hawaiian and Other Pacific Islanders compared to White patients in both samples. There was no evidence that perceived access mediated or moderated associations between Black race, Hispanic ethnicity, and hypertension or diabetes control.

CONCLUSIONS

We observed disparities in hypertension and diabetes control among minoritized patients. There was no evidence that patients' perception of access to primary care mediated or moderated these disparities. Reducing racial and ethnic disparities within VA in hypertension and diabetes control may require interventions beyond those focused on improving patient access.

Nurse Practitioner Care Environments and Racial and Ethnic Disparities in Hospitalization Among Medicare Beneficiaries with Coronary Heart Disease

BACKGROUND

Nurse practitioners care for patients with cardiovascular disease, particularly those from racial and ethnic minority groups, and can help assure equitable health outcomes. Yet, nurse practitioners practice in challenging care environments, which limits their ability to care for patients.

OBJECTIVE

To determine whether primary care nurse practitioner care environments are associated with racial and ethnic disparities in hospitalizations among older adults with coronary heart disease.

DESIGN

In this observational study, a cross-sectional survey was conducted among primary care nurse practitioners in 2018-2019 who completed a valid measure of care environment. The data was merged with 2018 Medicare claims data for patients with coronary heart disease.

PARTICIPANTS

A total of 1244 primary care nurse practitioners and 180,216 Medicare beneficiaries 65 and older with coronary heart disease were included.

MAIN MEASURES

All-cause and ambulatory care sensitive condition hospitalizations in 2018.

KEY RESULTS

There were 50,233 hospitalizations, 9068 for ambulatory care sensitive conditions. About 28% of patients had at least one hospitalization. Hospitalizations varied by race, being highest among Black patients (33.5%). Care environment moderated the relationship between race (Black versus White) and hospitalization (OR 0.93; 95% CI, 0.88-0.98). The lowest care environment was associated with greater hospitalization among Black (odds ratio=1.34; 95% CI, 1.20-1.49) compared to White beneficiaries. Practices with the highest care environment had no racial differences in hospitalizations. There was no interaction effect between care environment and race for ambulatory care sensitive condition hospitalizations. Nurse practitioner care environment had a protective effect on these hospitalizations (OR, 0.96; 95% CI, 0.92-0.99) for all beneficiaries.

CONCLUSIONS

Unfavorable care environments were associated with higher hospitalization rates among Black than among White beneficiaries with coronary heart disease. Racial disparities in hospitalization rates were not detected in practices with high-quality care environments, suggesting that improving nurse practitioner care environments could reduce racial disparities in hospitalizations.

Index Symptoms and Prognosis Awareness of Patients With Pancreatic Cancer: A Multi-Site Palliative Care Collaborative

BACKGROUND

Pancreatic cancer has a poor 5-year survival and carries significant morbidity. Pain is a commonly studied symptom in pancreatic cancer; however, few studies examine the frequency of multiple patient-reported symptoms. Our aim is to ascertain patient-reported symptom burden at initial consultation with a palliative care provider and compare patient prognostic awareness to provider estimation of prognosis.

METHODS

Data were extracted from the standardized Quality Data Collection Tool (QDACT). Adults with pancreatic cancer seen by a palliative care provider were included. Descriptive statistics were used to describe demographic features, symptom prevalence and burden, as well as assess patient prognosis awareness defined by congruence or incongruence with provider estimated prognosis.

RESULTS

285 patients were included in our analysis. The average age was 68 years (SD: 12.4), 87.2% were white, 50% male. The mean number of moderate/severe symptoms was 2.6 (SD: 2) out of 9 symptoms. Tiredness (66.7%), appetite (64.5%) and pain (46.2%) had the highest rates of moderate/severe symptom burden. Patients with a prognosis of 1-6 months had the lowest proportion of congruence with provider estimation (56.5%).

CONCLUSION

Our study suggests targets to improve patient-centered care of pancreatic cancer. Patients commonly have multiple symptoms that are moderate/severe at time of palliative care referral. While pain has been well-reported, tiredness and decreased appetite are more prevalent at initial visit. This emphasizes the importance of assessing multiple symptoms and working closely with palliative care for early referral. Overall, one third of patient prognosis estimates differed from the provider assessment of prognosis. Our data support the importance of early referral to palliative care to manage symptoms and better prepare patients for end-of-life care.

Contemporary Trends and Comparison of Racial Differences in Hospitalizations of Adults With Congenital Heart Disease

As advancements in care improve longevity in patients with congenital heart disease (CHD), it is crucial to further characterize this rapidly growing adult population. It is also essential that equitable care is offered across demographic groups. Hospitalizations for adults with CHD in the National Inpatient Sample were identified to describe trends in overall and cause-specific rates of admission per 1,000 adults with CHD from 2000 to 2018. Primary admission causes were then analyzed and stratified by race. An aggregate rate of left-ventricular assist device placements and heart transplants was calculated for each group and trended over the years. A total of 1,562,001 weighted hospitalizations were identified. Overall, annual rates of hospital admissions increased from 39 per 1,000 adults with CHD in 2000 to 74 per 1,000 in 2018, as did rates of cardiovascular admissions (16 of 1,000 to 34 of 1,000, p <0.001 for both). Transient ischemic attack/stroke (2.5 of 1,000 to 10.7 of 1,000), coronary artery disease (4.1 of 1,000 to 5.6 of 1,000), arrhythmias (2.8 of 1,000 to 4.6 of 1,000), and heart failure (2.8 of 1,000 to 5.0 of 1,000) were the most common cardiovascular primary causes of admission (other than CHD itself), and each significantly increased over time (p <0.001 for each). Mean age at all-cause and primary heart failure hospitalization increased for all races but remained 7 to 9 years younger for Black and Hispanic adults than White adults. In conclusion, hospitalization rates of adults with CHD in the United States increased from 2000 to 2018, largely driven by an increase in adults ≥55 years. Although the age at hospitalization increased overall, Black and Hispanic patients were substantially younger at presentation for advanced heart failure. Anticoagulation guidelines in this population may need revisiting as transient ischemic attack/stroke hospitalizations were frequent.

Increasing Equity While Improving the Quality of Care: JACC Focus Seminar 9/9

This review summarizes racial and ethnic disparities in the quality of cardiovascular care-a challenge given the fragmented nature of the health care delivery system and measurement. Health equity for all racial and ethnic groups will not be achieved without a substantially different approach to quality measurement and improvement. The authors adapt a tool frequently used in quality improvement work-the driver diagram-to chart likely areas for diagnosing root causes of disparities and developing and testing interventions. This approach prioritizes equity in quality improvement. The authors demonstrate how this approach can be used to create interventions that reduce systemic racism within the institutions and professions that deliver health care; attends more aggressively to social factors related to race and ethnicity that affect health outcomes; and examines how hospitals, health systems, and insurers can generate effective partnerships with the communities they serve to achieve equitable cardiovascular outcomes.

Improving quality in a complex primary care system-An example of refugee care and literature review

RATIONALE, AIMS AND OBJECTIVES

Applying traditional industrial quality improvement (QI) methodologies to primary care is often inappropriate because primary care and its relationship to the healthcare macrosystem has many features of a complex adaptive system (CAS) that is particularly responsive to bottom-up rather than top-down management approaches. We report on a demonstration case study of improvements made in the Family Health Center (FHC) of the JPS Health Network in a refugee patient population that illustrate features of QI in a CAS framework as opposed to a traditional QI approach.

METHODS

We report on changes in health system utilization by new refugee patients of the FHC from 2016 to 2017. We review the literature and summarize relevant theoretical understandings of quality management in complex adaptive systems as it applies to this case example.

RESULTS

Applying CAS principles in the FHC, utilization of the Emergency Department and Urgent Care Center by newly arrived refugee patients before their first clinic visit was reduced by more than half (total visits decreased from 31%-14% of the refugee patients). Our review of the literature demonstrates that traditional algorithmic top-down QI processes are most often unsuccessful in improving even a few single-disease metrics, and increases clinician burnout and penalizes clinicians who care for vulnerable patients. Improvement in a CAS occurs when front-line clinicians identify care gaps and are given the flexibility to learn and self-organize to enable new care processes to emerge, which are created from bottom-up leadership that utilize existing interdependencies and interact with the top levels of the organization through intelligent top-down causation. We give examples of early adapters who are better applying the principles of CAS change to their QI efforts.

CONCLUSIONS

Meaningful improvement in primary care is more likely achieved when the impetus to implement change shifts from top-down to bottom-up.

Association Between Black Race, Clinical Severity, and Management of Acute Pulmonary Embolism: A Retrospective Cohort Study

Background

Existing evidence indicates Black patients have higher incidence of pulmonary embolism (PE) and PE‐related mortality compared with other races/ethnicities, yet disparities in presenting severity and treatment remain incompletely understood.

Methods and Results

We retrospectively queried a multihospital healthcare system for all hospitalizations for acute PE (2012–2019). Of 10 329 hospitalizations, 8743 met inclusion criteria. Black patients (14.3%) were significantly younger (54.6±17.8 versus 63.1±16.6 years; P<0.001) and more female (56.1% versus 51.6%; P=0.003) compared with White patients. Using ordinal regression, Black race was significantly associated with higher PE severity after matching 1:3 on age and sex (1210:3264; odds ratio [OR], 1.08; 95% CI, 1.03–1.14), adjusting for clinical (OR, 1.13; 95% CI, 1.01–1.27), and socioeconomic (OR, 1.05; 95% CI, 1.05–1.35) characteristics. Among intermediate and high‐severity PE, Black race was associated with a decreased risk of intervention controlling for the competing risk of mortality and censoring on hospital discharge. This effect was modified by PE severity (P value <0.001), with a lower and higher risk of intervention for intermediate and high‐severity PE, respectively. Race was not associated with in‐hospital mortality (OR, 0.84; 95% CI, 0.69–1.02).

Conclusions

Black patients hospitalized with PE are younger with a higher severity of disease compared with White patients. Although Black patients are less likely to receive an intervention overall, this differed depending on PE severity with higher risk of intervention only for life‐threatening PE. This suggests nuanced racial disparities in management of PE and highlights the complexities of healthcare inequalities.

Preparedness for Serious Illnesses: Impact of Ethnicity, Mistrust, Perceived Discrimination, and Health Communication

BACKGROUND

Increasing severity of serious illness requires individuals to prepare and make decisions to mitigate adverse consequences of their illness. In a racial and ethnically diverse sample, the current study examined preparedness for serious illness among adults in California.

METHODS

This cross-sectional study used data from the Survey of California Adults on Serious Illness and End-of-Life 2019. Participants included 542 non-Hispanic White (52%), non-Hispanic Black (28%), and Hispanic (20%) adults who reported at least one chronic medical condition that they perceived to be a serious illness. Race/ethnicity, socio-demographic factors, health status, discrimination, mistrust, and communication with provider were measured. To perform data analysis, we used logistic regression models.

RESULTS

Our findings revealed that 19%, 24%, and 34% of non-Hispanic White, non-Hispanic Blacks, and Hispanic believed they were not prepared if their medical condition gets worse, respectively. Over 60% indicated that their healthcare providers never engaged them in discussions of their feelings of fear, stress, or sadness related to their illnesses. Results of bivariate analyses showed that race/ethnicity was associated with serious illness preparedness. However, multivariate analysis uncovered that serious illness preparedness was only lower in the presence of medical mistrust in healthcare providers, perceived discrimination, less communication with providers, and poorer quality of self-rated health.

CONCLUSION

This study draws attention to the need for healthcare systems and primary care providers to engage in effective discussions and education regarding serious illness preparedness with their patients, which can be beneficial for both individuals and family members and increase quality of care.

Discrimination and Medical Mistrust in a Racially and Ethnically Diverse Sample of California Adults

PURPOSE

Although we know that racial and ethnic minorities are more likely to have mistrust in the health care system, very limited knowledge exists on correlates of such medical mistrust among this population. In this study, we explored correlates of medical mistrust in a representative sample of adults.

METHODS

We analyzed cross-sectional study data from the Survey of California Adults on Serious Illness and End-of-Life 2019. We ascertained race/ethnicity, health status, perceived discrimination, demographics, socioeconomic factors, and medical mistrust. For data analysis, we used multinomial logistic regression models.

RESULTS

Analyses were based on 704 non-Hispanic Black adults, 711 Hispanic adults, and 913 non-Hispanic White adults. Racial/ethnic background was significantly associated with the level of medical mistrust. Adjusting for all covariates, odds of reporting medical mistrust were 73% higher (adjusted odds ratio [aOR] = 1.73; 95% CI, 1.15-2.61, P <.01) and 49% higher (aOR = 1.49; 95% CI, 1.02-2.17, P <.05) for non-Hispanic Black and Hispanic adults when compared with non-Hispanic White adults, respectively. Perceived discrimination was also associated with higher odds of medical mistrust. Indicating perceived discrimination due to income and insurance was associated with 98% higher odds of medical mistrust (aOR = 1.98; 95% CI, 1.71-2.29, P <.001). Similarly, the experience of discrimination due to racial/ethnic background and language was associated with a 25% increase in the odds of medical mistrust (aOR = 1.25; 95% CI, 1.10-1.43; P <.001).

CONCLUSIONS

Perceived discrimination is correlated with medical mistrust. If this association is causal, that is, if perceived discrimination causes medical mistrust, then decreasing such discrimination may improve trust in medical clinicians and reduce disparities in health outcomes. Addressing discrimination in health care settings is appropriate for many reasons related to social justice. More longitudinal research is needed to understand how complex societal, economic, psychological, and historical factors contribute to medical mistrust. This type of research may in turn inform the design of multilevel community- and theory-based training models to increase the structural competency of health care clinicians so as to reduce medical mistrust.

Explaining racial-ethnic differences in hypertension and diabetes control among veterans before and after patient-centered medical home implementation

Patient-centered medical homes (PCMH) are primary care delivery models that improve care access and population-level health outcomes, yet they have not been observed to narrow racial-ethnic disparities in the Veteran Health Administration (VHA) or other health systems. We aimed to identify and compare underlying drivers of persistent hypertension and diabetes control differences between non-Hispanic Black (Black) and Hispanic versus non-Hispanic White (White) patients before and after PCMH implementation in the VHA. Among Black and Hispanic versus White VHA primary care patients in 2009 (nhypertension = 26,906; ndiabetes = 21,141) and 2014 (nhypertension = 83,809; ndiabetes = 38,887), we retrospectively examined hypertension control (blood pressure<140/90) and diabetes control (hemoglobin A1c <9) obtained through random chart abstraction of patient health records nationally via VHA's quality monitoring program. We fit linear probability regression models, adjusting for age, gender, comorbidity, and socioeconomic status (SES). Blinder-Oaxaca and Smith-Welch decomposition methods were used to parse out explained and unexplained contributors to health disparity between racial-ethnic groups pre- and post-PCMH implementation. Compared to White patients, hypertension and diabetes control remained significantly lower for Black (-6.2%[0.4%] and -3.1%[0.6%], respectively; p's<0.001) and Hispanic (-1.4%[0.8%] and -4.0%[1.0%], respectively; p's<0.001) patients following VHA PCMH implementation. Most racial-ethnic differences (55.7-92.3%; all p<0.05) were not attributed to age, gender, comorbidity, and SES. The contribution of explained versus unexplained factors did not significantly change over time. While many explanations for persistent racial-ethnic disparities in disease control among veterans exist, our study did not find that it was due to an influx of "sick" or "socioeconomically vulnerable" patients into the VHA following PCMH implementation. Instead, unexplained differences may be due to differential healthcare and community experiences (e.g., discrimination). Understanding underlying pathways leading to health disparities will better inform policy and clinical interventions to improve PCMH care delivery to racial-ethnic minority patients in health systems.

Cardiovascular Diseases in African Americans: Fostering Community Partnerships to Stem the Tide

In 2002, the Institute of Medicine highlighted community partnerships as important in strategies for ensuring the public's health in the 21st century. Whether defined narrowly as the neighborhood or more broadly as the entire nation, communities represent settings in which health is supported and protected by healthy social connections and environments or risked and damaged by detrimental social, environmental, and policy determinants, as well as adverse behavioral and lifestyle choices. In this article, cardiovascular disease in African Americans is used as an example to highlight the successes achieved during the last half-century in reducing mortality rates, the persisting challenge of suboptimal adoption of evidence-based practices to promote community health and prevent disease, and the still widespread and pervasive health disparities. The article concludes with a call for the scientific community to embrace implementation research in strategic partnership with community stakeholders to stem the tide of cardiovascular disease and reduce related cardiovascular health disparities.

Racial/Ethnic Disparities in Neonatal Intensive Care: A Systematic Review

CONTEXT

Racial and ethnic disparities in health outcomes of newborns requiring care in the NICU setting have been reported. The contribution of NICU care to disparities in outcomes is unclear.

OBJECTIVE

To conduct a systematic review of the literature documenting racial/ethnic disparities in quality of care for infants in the NICU setting.

DATA SOURCES

Medline/PubMed, Scopus, Cumulative Index of Nursing and Allied Health, and Web of Science were searched until March 6, 2018, by using search queries organized around the following key concepts: "neonatal intensive care units," "racial or ethnic disparities," and "quality of care."

STUDY SELECTION

English language articles up to March 6, 2018, that were focused on racial and/or ethnic differences in the quality of NICU care were selected.

DATA EXTRACTION

Two authors independently assessed eligibility, extracted data, and cross-checked results, with disagreements resolved by consensus. Information extracted focused on racial and/or ethnic disparities in quality of care and potential mechanism(s) for disparities.

RESULTS

Initial search yielded 566 records, 470 of which were unique citations. Title and abstract review resulted in 382 records. Appraisal of the full text of the remaining 88 records, along with the addition of 5 citations from expert consult or review of bibliographies, resulted in 41 articles being included.

LIMITATIONS

Quantitative meta-analysis was not possible because of study heterogeneity.

CONCLUSIONS

Overall, this systematic review revealed complex racial and/or ethnic disparities in structure, process, and outcome measures, most often disadvantaging infants of color, especially African American infants. There are some exceptions to this pattern and each area merits its own analysis and discussion.

Do racial and ethnic disparities in health care use vary with health?

OBJECTIVE

To determine the relationship between health status and the magnitude of black-white and Hispanic-white disparities in the likelihood of having any office-based or hospital outpatient department visits, as well as number of visits.

DATA SOURCE

2010-2014 Medical Expenditure Panel Survey.

STUDY DESIGN

The probability of having a visit is modeled using a Probit model, and the number of visits using a negative binomial model. We use a nonlinear rank-and-replace method to adjust minority health status to be comparable to that of whites, and predict utilization at different levels of health by fixing an indicator of health status. We compare estimated differences in predicted utilization across racial/ethnic groups for each level of health status to map out the relationship between the racial/ethnic disparity and health status, also stratifying by health insurance coverage.

EXTRACTION METHODS

We subset to nonelderly adults.

PRINCIPAL FINDINGS

We find that Hispanic-white differences in the probability of having an office-based or hospital outpatient department were widest among adults in excellent health (27 percentage points, 95% CI: [23, 31]) and narrowest when reporting poor or fair health (15 p.p. [13, 17]). Black-white and Hispanic-white differences in the number of visits were wider for adults who report poor or fair health (5.3 visits [4.0, 6.6] and 5.7 [4.3, 7.0], respectively) compared to excellent health (1.7 [1.2, 2.1] and 1.5 [1.1, 2.0], respectively) among adults who are full-year privately insured.

CONCLUSIONS

The magnitudes of racial/ethnic disparities vary with level of health.
