Racial/ethnic differences in treatment recommendations: lifestyle changes and medication prescriptions for high cholesterol

Using Patient Decision Aids for Cardiology Care in Diverse Populations

PURPOSE OF REVIEW

Patient decision aids (PDAs) are tools that help guide treatment decisions and support shared decision-making when there is equipoise between treatment options. This review focuses on decision aids that are available to support cardiac treatment options for underrepresented groups.

RECENT FINDINGS

PDAs have been developed to support multiple treatment decisions in cardiology related to coronary artery disease, valvular heart disease, cardiac arrhythmias, heart failure, and cholesterol management. By considering the unique needs and preferences of diverse populations, PDAs can enhance patient engagement and promote equitable healthcare delivery in cardiology. In this review, we examine the benefits, challenges, and current trends in implementing PDAs, with a focus on improving decision-making processes and outcomes for patients from underrepresented racial and ethnic groups. In addition, the article highlights key considerations when implementing PDAs and potential future directions in the field.

Association Between Dietary and Serum Cholesterol and Cognitive Function Among the U.S. Elderly from NHANES 2011-2014

BACKGROUND

The association between dietary or serum cholesterol and cognitive performance in older adults has not been well-established.

OBJECTIVE

This study aimed to investigate the potential association between dietary or serum cholesterol and cognitive performance in the elderly population.

METHODS

A cross-sectional analysis was conducted using data from the National Health and Nutrition Examination Survey (NHANES) 2011-2012 and 2013-2014. Diet and supplement cholesterol was estimated based on two non-consecutive 24-hour dietary recalls. Cognitive function was assessed using various statistical tests. Poor cognitive performance was defined as scores below the lowest quartile within age groups. Regression models were adjusted for demographic factors, and subgroup analyses were performed for non-Hispanic White (NHW) and non-Hispanic Black (NHB) individuals.

RESULTS

Among 759 participants aged 60 years and above, dietary cholesterol was only associated with dietary saturated fatty acids and serum high-density lipoprotein cholesterol. There was no evidence of an association between dietary cholesterol and cognitive function, except for NHB individuals, where dietary cholesterol showed a positive correlation with cognitive function. In the overall sample and NHW participants, there were consistent positive associations between serum total cholesterol and cognitive performance across statistical tests, while such associations were rare among NHB individuals. Although not statistically significant, NHB individuals had higher dietary/supplementary/total cholesterol intake compared with NHW individuals.

CONCLUSION

Within the normal range, increasing serum cholesterol may be a potential factor to prevent or relieve cognitive dysfunction. However, ethnic differences should be taken into account when considering the association between cholesterol and cognitive performance.

How the National Ambulatory Medical Care Survey has been used to identify health disparities in the care of patients in the United States

BACKGROUND

Healthcare disparities negatively impact patient health outcomes; addressing disparities could improve quality of life and decrease overall healthcare cost. The National Ambulatory Medical Care Survey (NAMCS) is an objective and reliable source for collecting information on United States (U.S.) ambulatory medical care service visits and may be a useful tool for identifying potential disparities in care.

OBJECTIVE

The purpose of this literature review is to describe studies utilizing NAMCS to capture U.S. healthcare disparities.

METHODS

PubMed was searched for scientific articles that utilized NAMCS to determine health disparities in the U.S. The keywords queried included "NAMCS" or "National Ambulatory Medical Care Survey" and "disparity" or "disparities" as a pair or additionally paired with one of the following: "race", "ethnicity", "age", "gender", "geography", or "insurance".

RESULTS

66 studies were found that incorporated NAMCS data from 1980-2016 into their methods to measure outcomes relating to health disparities. Disparities were found in the following categories: race/ethnicity, geographic location, age, insurance type, gender, specialist care versus primary care, body habitus, and preexisting conditions affecting patient outcomes. Disparities were identified in pain management, neurology, dermatology, psychiatry, patient communication access, and non-specialty specific or primary care visits related to disease conditions, screening, and treatment plans.

LIMITATIONS

Only PubMed was utilized as a search engine and may not encompass all studies on NAMCS and health disparities. NAMCS is a cross-sectional database and does not allow for longitudinal analyses.

CONCLUSIONS

NAMCS may be an underused tool given the limited number of articles that identify health disparities using it. Research studies utilizing NAMCS may identify potential disparities ultimately leading to better healthcare outcomes.
