Reducing racial and ethnic disparities in hypertension prevention and control: what will it take to translate research into practice and policy?

ABSTRACT: INTRODUCTION:Despite available, effective therapies, racial and ethnic disparities in care and outcomes of hypertension persist. Several interventions have been tested to reduce disparities; however, their translation into practice and policy is hampered by knowledge gaps and limited collaboration among stakeholders. METHODS:We characterized factors influencing disparities in blood pressure (BP) control by levels of an ecological model. We then conducted a literature search using PubMed, Scopus, and CINAHL databases to identify interventions targeted toward reducing disparities in BP control, categorized them by the levels of the model at which they were primarily targeted, and summarized the evidence regarding their effectiveness. RESULTS:We identified 39 interventions and several state and national policy initiatives targeted toward reducing racial and ethnic disparities in BP control, 5 of which are ongoing. Most had patient populations that were majority African-American. Of completed interventions, 27 demonstrated some improvement in BP control or related process measures, and 7 did not; of the 6 studies examining disparities, 3 reduced, 2 increased, and 1 had no effect on disparities. CONCLUSIONS:Several effective interventions exist to improve BP in racial and ethnic minorities; however, evidence that they reduce disparities is limited, and many groups are understudied. To strengthen the evidence and translate it into practice and policy, we recommend rigorous evaluation of pragmatic, sustainable, multilevel interventions; institutional support for training implementation researchers and creating broad partnerships among payers, patients, providers, researchers, policymakers, and community-based organizations; and balance and alignment in the priorities and incentives of each stakeholder group.

Project description:ImportanceWith the stabilization of breast cancer incidence and substantial improvement in survival, more attention has focused on postmastectomy breast reconstruction (PBR). Despite its demonstrated benefits, wide disparities in the use of PBR remain. Physician-patient communication has an important role in disparities in health care, especially for elective surgical procedures. Recognizing this, the State of New York enacted Public Health Law (NY PBH Law) 2803-o in 2011 mandating that physicians communicate about reconstructive surgery with patients undergoing mastectomy.ObjectiveTo evaluate whether mandated physician-patient communication is associated with reduced racial/ethnic disparities in immediate PBR (IPBR).Design, setting, and participantsThis retrospective study used state inpatient data from January 1, 2008, through December 31, 2011, in New York and California to evaluate a final sample of 42 346 women aged 20 to 70 years, including 19 364 from New York (treatment group) and 22 982 from California (comparison group). The primary hypothesis tested the effect of the New York law on racial/ethnic disparities, using California as a comparator. The National Academy of Medicine's (formerly Institute of Medicine) definition of a disparity was applied, and a difference-in-differences method (before-and-after comparison design) was used to evaluate the association of NY PBH Law 2803-o mandating physician-patient communication with disparities in IPBR. Data were analyzed from July 1, 2016, to February 24, 2017.ExposuresNew York PBH Law 2803-o was implemented on January 1, 2011. The preexposure period included January 1, 2008, through December 31, 2010 (3 years); the postexposure period, January 1 through December 31, 2011 (1 year).Main outcomes and measuresThe primary outcome was use of IPBR among white, African American, Hispanic, and other minority groups before and after the implementation of NY PBH Law 2803-o.ResultsAmong the 42 346 women (mean [SD] age, 53 [10] years), 65.3% (27 654) were white, 12.7% (5365) were Hispanic, 9.4% (3976) were African American, and 12.6% (5351) were other minorities. The new legislation was not associated with the overall IPBR rate or disparity in IPBR between whites and African Americans (reduction of 1 percentage point; 95% CI, -0.02 to 0.04), but it was associated with a reduction in disparities in IPBR between Hispanic and white patients by 9 (95% CI, 0.06-0.11) percentage points and between other minorities and white patients by 13 (95% CI, 0.11-0.16) percentage points.Conclusions and relevancePhysician-patient communication may help to address inequity in the use of elective surgical procedures, such as IPBR. However, lack of patient trust and/or effective physician-patient communication may reduce the potential effect of mandatory communication for some subpopulations, including African American individuals.

Project description:IntroductionDetailed evaluations of racial and ethnic trends and disparities in NSCLC outcomes are lacking, and it remains unclear whether recent advances in screening and targeted therapies for NSCLC have benefited all population groups equally.MethodsUsing the Surveillance, Epidemiology, and End Results 18-registry data, we evaluated trends in overall and stage-specific NSCLC incidence (2007-2018) among patients aged 55 to 79 years by sex and race and ethnicity. Overall and stage-specific 2-year cause-specific survival rates were calculated by sex and race and ethnicity. Health Disparities software calculated absolute (difference) and relative (ratio) disparity measures comparing racial and ethnic groups with the highest and lowest rates (range measures) and comparing white patients (reference group) with other groups (pairwise rate measures). Joinpoint software assessed changes in rates and disparities.ResultsBoth men and women experienced substantial declines in NSCLC incidence from 2007 to 2018, largely due to significant declines in the incidence of distant-stage NSCLC over the study period (p < 0.05). During the same time period, the incidence of local-stage NSCLC significantly increased among black and Hispanic women (p < 0.05) and remained stable among all other groups. Overall, 2-year cause-specific survival rates improved across most racial and ethnic groups, especially among those diagnosed in regional and distant stages. For both sexes, absolute disparities in overall and stage-specific incidence of NSCLC significantly decreased over time (p < 0.05), whereas relative disparities remained unchanged. Pairwise comparison revealed persistent disparities in NSCLC burden between black and white men.ConclusionWe found evidence of narrowing racial and ethnic disparities in NSCLC incidence over time; however, important disparities persist. More work is needed to ensure consistent and equitable access to high-quality screening, diagnosis, and treatment to reduce and eliminate cancer disparities.

Project description:ObjectivesThe prevalence of childhood obesity is significantly higher among racial and/or ethnic minority children in the United States. It is unclear to what extent well-established obesity risk factors in infancy and preschool explain these disparities. Our objective was to decompose racial and/or ethnic disparities in children's weight status according to contributing socioeconomic and behavioral risk factors.MethodsWe used nationally representative data from ∼10 700 children in the Early Childhood Longitudinal Study Birth Cohort who were followed from age 9 months through kindergarten entry. We assessed the contribution of socioeconomic factors and maternal, infancy, and early childhood obesity risk factors to racial and/or ethnic disparities in children's BMI z scores by using Blinder-Oaxaca decomposition analyses.ResultsThe prevalence of risk factors varied significantly by race and/or ethnicity. African American children had the highest prevalence of risk factors, whereas Asian children had the lowest prevalence. The major contributor to the BMI z score gap was the rate of infant weight gain during the first 9 months of life, which was a strong predictor of BMI z score at kindergarten entry. The rate of infant weight gain accounted for between 14.9% and 70.5% of explained disparities between white children and their racial and/or ethnic minority peers. Gaps in socioeconomic status were another important contributor that explained disparities, especially those between white and Hispanic children. Early childhood risk factors, such as fruit and vegetable consumption and television viewing, played less important roles in explaining racial and/or ethnic differences in children's BMI z scores.ConclusionsDifferences in rapid infant weight gain contribute substantially to racial and/or ethnic disparities in obesity during early childhood. Interventions implemented early in life to target this risk factor could help curb widening racial and/or ethnic disparities in early childhood obesity.
