Family Management of Hypertension in Brazil: A Cross-Sectional Study

Sales, P. C. D., McCarthy, M. M., Dickson, V. V., Sullivan-Bolyai, S., D’Eramo Melkus, G., & Chyun, D. (2025). Clinical Nursing Research, 34(1), 12-22. 10.1177/10547738241282114
Abstract
Abstract
In Brazil, research indicates that primary family members are the main source of support for individuals with chronic conditions such as hypertension (HTN). The burden of caregiving not only hinders effective HTN management but can also cause stress and anxiety, potentially leading to HTN in caregivers. Despite this, few studies have explored the impact of caregiving on these family members. Aims of the study were to: (1) Describe the prevalence of blood pressure (BP) control in family members of individuals with HTN; (2) identify family member perspectives on facilitators and barriers to HTN management; and (3) identify influences that help or interfere with family member functioning (levels of stress, quality of life [QOL], and caregiver burden). This descriptive, cross-sectional study included 213 family members randomly selected from 3 Family Health Strategy units. Family members were largely female (n = 143; 67.1%); the mean age was 60.1 years (SD ± 17.02) and 42.6% (n = 96) had less than a high school education. The three most important facilitators and barriers were related to medication, medical visits, healthy eating, physical activity, and stress. The mean systolic BP was 132.7 (SD ± 21.9) mmHg and a diastolic BP of 85.9 (SD ± 18.1) mmHg with 120 (56.3%) of family members classified as having normal BP. In regard to family member contributions to the self-care of the individual with HTN, family members displayed low levels of self-care maintenance (n = 148; 69.4%) and management (n = 47; 71.2%) support, while a slight majority (n = 114; 53.5%) had adequate levels of self-care confidence in supporting the individual with HTN. Family members (n = 189; 88.8%) showed moderate-to-high levels of perceived stress, but good physical (n = 189; 88.7%) and mental QOL (n = 196; 92%) and low levels of caregiver burden (n = 113; 53.1%). A variety of contextual sociocultural influences were associated with the outcomes under study. Family-based interventions are urgently needed to address the inadequate management of HTN.

Woersching, J., Van Cleave, J., Gonsky, J. P., Ma, C., Haber, J., Chyun, D., & Egleston, B. L. (2024). Cancer Causes and Control. 10.1007/s10552-024-01921-0
Abstract
Abstract
Purpose: Mental health disorders, substance abuse, and tobacco use are prevalent in the US population. However, the association between these conditions and head and neck cancer (HNC) stage is poorly understood. This research aims to uncover the relationship between pre-existing mental health disorders, substance abuse, and tobacco use and HNC stage at diagnosis in patients receiving care in an integrated, public safety-net healthcare system. Methods: This study was a secondary data analysis of linked hospital tumor registries and electronic health record (EHR) data. The study’s primary independent variables were the comorbidities of mental health disorders, substance abuse, and tobacco use. The dependent variable was HNC stage at diagnosis, operationalized as early stage (i.e., stages I, II, and III) and advanced stage (stage IV, IVA, IVB, or IVC). The analysis included multivariable logistic regression adjusted for covariates of demographic variables, tumor anato Results: The study population consisted of 357 patients with median age of 59 years, and was primarily male (77%), diverse (Black or African American 41%; Hispanic 22%), and from neighborhoods with low income (median average annual household income $39,785). Patients with a history of mental health disorders with or without tobacco use had significantly lower odds of advanced stage HNC at diagnosis (adjusted OR = 0.35, 95% Confidence Interval [CI]: 0.17–0.72.) while patients with a history of substance abuse with or without tobacco use had significantly higher odds of advanced stage HNC at diagnosis (adjusted OR 1.41, 95% CI: 1.01–1.98) than patients with no history of mental health disorders, substance abuse, or tobacco use. Conclusions: The relationship between HNC stage at diagnosis and the comorbidities of mental health disorders, substance abuse, or tobacco differs depending on the type and co-occurrence of these comorbidities. These findings demonstrate the need for innovative care delivery models and education initiatives tailored to meet the needs of patients with mental health disorders, substance abuse, and tobacco use that facilitate early detection of HNC.

De Sales, P. C., Mccarthy, M. M., Dickson, V. V., Sullivan-Bolyai, S., D’Eramo Melkus, G., & Chyun, D. (2024). Journal of Cardiovascular Nursing. 10.1097/JCN.0000000000001108
Abstract
Abstract
Background The prevalence of hypertension (HTN) is high in Brazil, and control rates are low. Little is known about the factors that contribute to HTN control from a family-based perspective. Objectives Guided by the Family Management Style Framework, specific aims were to (1) describe the prevalence of adequate blood pressure (BP) control in individuals cared for the Family Health Strategy, (2) identify facilitators and barriers to HTN management, and (3) identify individual contextual sociocultural influences (sociocultural context and social and Family Health Strategy support), definition of the situation, and management behaviors that help or interfere with individual functioning (BP control in the individual with HTN). Methods This descriptive, cross-sectional study included 213 individuals with HTN randomly selected from 3 Family Health Strategy units from July 2016 until July 2017. Results Most of the individuals were female (n = 139, 65.3%), retired (n = 129, 60.5%), and White (n = 129, 60.2%) and had less than a high school education (n = 123, 57.6%). Family income (n = 166, 77.8%) was less than 5500 reals (US $1117/month). Mean (SD) systolic BP was 137.1 (±24.1) mm Hg, and mean (SD) diastolic BP was 83.8 (±18.6) mm Hg, with 47.9% (n = 102) having uncontrolled BP. In the multivariate logistic model, only high levels of perceived social support were significantly associated (odds ratio, 3.29; 95% confidence interval, 1.44-7.5; P =.005) with controlled BP. Conclusions Social support is strongly associated with BP control. Optimizing support may play an important role in BP control and preventing HTN-related complications.

Abstract
Abstract
Background: Nurses’ knowledge of heart failure (HF) is highly variable, ranging from expert to poor, potentially leading to inadequate self-care. Objectives: (1) document the knowledge variation of HF assessment and management among specialist and generalist nurses; (2) determine factors that may be associated with nurses’ knowledge; and (3) describe nurses’ views of knowledge deficits and ways to improve nurses’ knowledge to better meet the needs educational interventions. Method: Members of the American Association of Heart Failure Nurses and Registered Nurses were invited to participate in a cross-sectional survey. Independent samples t-test, chi-square, and linear regression were used for quantitative analysis. Text analysis was applied to analyze the themes of qualitative comments. Results: A total of 918 nurses completed the survey. Specialist nurses had higher scores than generalist nurses with statistically significant F-test for diet, fluid, signs/symptoms, medication, and exercise. Both specialist and generalist nurses were least knowledgeable about dry weight, asymptomatic hypotension, and transient dizziness. Being a specialist nurse was associated with higher level of knowledge scores. Years of experience and race were significant factors associated with knowledge scores in generalist nurses. Confidence level and race were significant predictors for specialist nurses. Three themes emerged regarding the cause of nurses’ insufficient knowledge and several approaches were provided. Conclusions: Specialist nurses are not only knowledgeable, but their knowledge levels are less variable compared to generalist nurses. There is a need to identify additional factors that may potentially influence nurses’ knowledge, contributing to the effectiveness of interventions.

Abstract
Abstract
Cardiovascular disease remains the leading cause of death in patients with diabetes. Cardiovascular disease in diabetes is multifactorial, and control of the cardiovascular risk factors leads to substantial reductions in cardiovascular events. The 2015 American Heart Association and American Diabetes Association scientific statement, "Update on Prevention of Cardiovascular Disease in Adults With Type 2 Diabetes Mellitus in Light of Recent Evidence," highlighted the importance of modifying various risk factors responsible for cardiovascular disease in diabetes. At the time, there was limited evidence to suggest that glucose-lowering medications reduce the risk of cardiovascular events. At present, several large randomized controlled trials with newer antihyperglycemic agents have been completed, demonstrating cardiovascular safety and reduction in cardiovascular outcomes, including cardiovascular death, myocardial infarction, stroke, and heart failure. This AHA scientific statement update focuses on (1) the evidence and clinical utility of newer antihyperglycemic agents in improving glycemic control and reducing cardiovascular events in diabetes; (2) the impact of blood pressure control on cardiovascular events in diabetes; and (3) the role of newer lipid-lowering therapies in comprehensive cardiovascular risk management in adults with diabetes. This scientific statement addresses the continued importance of lifestyle interventions, pharmacological therapy, and surgical interventions to curb the epidemic of obesity and metabolic syndrome, important precursors of prediabetes, diabetes, and comorbid cardiovascular disease. Last, this scientific statement explores the critical importance of the social determinants of health and health equity in the continuum of care in diabetes and cardiovascular disease.

Abstract
Abstract
EHRs provide an opportunity to conduct research on underrepresented oncology populations with mental health and substance use disorders. However, a lack of data quality may introduce unintended bias into EHR data. The objective of this article is describe our analysis of data quality within automated comorbidity lists commonly found in EHRs. Investigators conducted a retrospective chart review of 395 oncology patients from a safety-net integrated healthcare system. Statistical analysis included κ coefficients and a condition logistic regression. Subjects were racially and ethnically diverse and predominantly used Medicaid insurance. Weak κ coefficients (κ = 0.2-0.39, P <.01) were noted for drug and alcohol use disorders indicating deficiencies in comorbidity documentation within the automated comorbidity list. Further, conditional logistic regression analyses revealed deficiencies in comorbidity documentation in patients with drug use disorders (odds ratio, 11.03; 95% confidence interval, 2.71-44.9; P =.01) and psychoses (odds ratio, 0.04; confidence interval, 0.02-0.10; P <.01). Findings suggest deficiencies in automatic comorbidity lists as compared with a review of provider narrative notes when identifying comorbidities. As healthcare systems increasingly use EHR data in clinical studies and decision making, the quality of healthcare delivery and clinical research may be affected by discrepancies in the documentation of comorbidities.

The Effect of Psychosocial Factors and Functional Independence on Poststroke Depressive Symptoms: A Cross-Sectional Study

Babkair, L. A., Chyun, D., Dickson, V. V., & Almekhlafi, M. A. (2022). Journal of Nursing Research, 30(1), E189. 10.1097/JNR.0000000000000464
Abstract
Abstract
Background Stroke is the second leading cause of death and a major cause of serious, long-term disability worldwide. The approximately 15 million people each year who experience stroke are at risk of developing depression. Poststroke depressive symptoms affect one third of survivors of stroke. Patients who develop poststroke depressive symptoms experience decreased functional independence, poor cognitive recovery, decreased quality of life, and increased mortality. Survivors of stroke use social support to deal with stress and defend against the adverse effects of negative stroke outcomes. Purpose This study was designed to examine the influence of perceived social support (emotional and informational, tangible, affectionate, and positive social interaction), stress level, and functional independence on depressive symptoms in survivors of stroke. Methods A cross-sectional observational study design in outpatient settings and rehabilitation centers was conducted. A convenience sample of 135 survivors of stroke completed the psychometrically valid instruments. Results Most of the sample had mild or moderate depressive symptoms (26% and 29%, respectively). The mean score for perceived social support was 77.53 (SD = 21.44) on the Medical Outcomes Study Social Support Survey. A negative association was found between depressive symptoms and the social support total score (r = -.65, p <.01). All of the social support subcategories were negatively associated with depressive symptoms. Hierarchical multiple linear regression showed that social support, stress level, and literacy were associated with depressive symptoms (β = -.31, p <.001; β =.45, p <.001; and β =.16, p =.01, respectively) and partially mediated the association between depressive symptoms and functional independence. Conclusions/Implications for Practice Poststroke depressive symptoms are common among survivors of stroke. Social support may improve health by protecting these individuals from the negative outcomes of stroke and enhance their recovery. Future research is required to examine how related interventions improve social support in caregivers and reduce depressive symptoms in stroke survivors.

Back pain and heart failure in community-dwelling older adults: Findings from the Health ABC study

Chen, J., Zhang, Y., Simonsick, E., Starkweather, A., Chen, M. H., McCauley, P., Chyun, D., & Cong, X. (2021). Geriatric Nursing, 42(3), 643-649. 10.1016/j.gerinurse.2021.03.016
Abstract
Abstract
This study explored the association of back pain and heart failure (HF) with health outcomes among community-dwelling older adults. Older adults who completed a follow-up in the 11th year (2007–2008) of the Health, Aging, and Body Composition (Health ABC) study were included. The mean age was 83.4 ± 2.78 years. Back pain and heart failure were reported by 55.40% (n = 657) and 8.09 % (n = 96) of the total subjects (N = 1186), respectively. Regression analysis indicated that older adults with back pain reported worse depressive symptoms, fatigue, and physical performance and function compared with those without back pain (p < 0.05), and HF presence increased fatigue levels and decreased physical function (p < 0.05) among older adults with back pain. The high incidence and negative impact of back pain highlight the need to develop strategies for pain management among older adults with and without HF.
