Individual and systems-related factors associated with heart failure self-care: a systematic review.

BACKGROUND: Heart failure (HF) is a prevalent condition worldwide. HF self-care is a set of behaviors necessary for improving patient outcomes. This study aims to review and summarize the individual and system-related factors associated with HF self-care published in the last seven years (Jan 2015 - Dec 2021) using the Socioecological Model as a review framework. METHODS: An experienced nursing librarian assisted authors in literature searches of CINAHL Plus with Full Text, Ovid Nursing, PsychINFO, and PubMed databases for peer-reviewed descriptive studies. Inclusion criteria were HF sample with self-care as the outcome variable, and a quantitative descriptive design describing individual and/or system-level factors associated with self-care. Exclusion criteria were interventional or qualitative studies, reviews, published before 2015, non-English, and only one self-care behavior as the outcome variable. The search yielded 1,649 articles. Duplicates were removed, 710 articles were screened, and 90 were included in the full-text review. RESULTS: A subset of 52 articles met inclusion and exclusion criteria. Study quality was evaluated using modified STROBE criteria. Study findings were quantitated and displayed based on socioecological levels. Self-care confidence, HF knowledge, education level, health literacy, social support, age, depressive symptoms, and cognitive dysfunction were the most frequently cited variables associated with self-care. Most factors measured were at the individual level of the Socioecological Model. There were some factors measured at the microsystem level and none measured at the exosystem or macrosystem level. CONCLUSION: Researchers need to balance the investigation of individual behaviors that are associated with HF self-care with system-level factors that may be associated with self-care to better address health disparities and inequity.

African-Americans Have a Higher Propensity for Death from COVID-19: Rationale and Causation.

The purpose of this article is to provide an understanding about the mechanisms that contribute to the proliferation of COVID-19 morbidity and mortality among high-risk populations, and especially African-Americans. African-Americans are succumbing to novel SARS-CoV-2 (COVID-19) at an alarming rate. Current data indicate that while African-Americans represent less than 13.4% of the United States' population, they account for one-third of more than 4.77 million persons with verified COVID-19 infections. Currently, more than 50,258 African-Americans have succumbed to the disease. African-Americans are disproportionately impacted by COVID-19 to an extent unobserved in other racial/ethnic subgroups. In addition, this article describes the physiological event inflammation-mediation storming (cytokine storming). Social determinants of health such as income, education, and employment are hypothesized to impact cogent health care delivery for African-Americans. Included in this article are data on clinical outcomes that highlight the role of pre-existing (health disparities) conditions like diabetes, hypertension, cardiovascular disease, obesity, and lung disease, as barriers to optimal outcomes among African-Americans who are hospitalized with COVID-19. Also explored in this article is causation for vascular complications. A further aim of this article is to provide insight into cause and effect rationales for COVID-19 and health disparities, from both biosocial and health inequality perspectives. Linkages between these selected health disparities and COVID-19 are examined to determine possible deteriorating effects of COVID-19. Finally, techniques are offered to render culturally competent care to African-Americans diagnosed with COVID-19 who present concomitantly with health disparities.

Chloroquine and Hydroxychloroquine for the Treatment of COVID-19: Review and Appraisal of Current Evidence.

Novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and associated coronavirus disease 19 (COVID-19) began ravaging most of the globe in November 2019. In the United States more than 25 million people have been infected with SARS-CoV-2. To date, COVID-19 has killed close to 400,000 U.S. citizens. In the face of limited pharmacotherapies, the current burden of SARS-CoV-2 and COVID-19 signals overwhelming sickness and trillions in healthcare costs ahead. The need to expeditiously identify safe and efficacious prophylaxis and treatment options is critical. Drug repositioning may be a promising strategy toward mitigating the impact of SARS-CoV-2 and COVID-19. This rapid review appraises available evidence on the viability of vintage antimalarial drugs chloroquine (CHQ) and its analog hydroxychloroquine (HCQ) repositioned for SARS-CoV-2 prophylaxis and COVID-19 treatment. Findings suggest neither the use of CHQ nor HCQ singularly, or concomitantly, with azithromycin and/or zinc provide definitive benefits for use against SARS-CoV-2 infection or COVID-19 illness. Moreover, administration of these medications was linked to significant and sometimes fatal complications.

Heart Failure Among African-Americans: Suggested Culturally Appropriate Intervention Strategies.

Cardiovascular disease is a serious problem in the United States. It is the most common cause of death among African-Americans. Heart failure is associated with poor health outcomes and a diminished quality of life. Some of the issues that affect the health of African-Americans with heart failure are cost of health care, their access to care, and the quality of that care. The aim of this paper is to identify those issues that are related to cost, quality, and access to health care in African-Americans with heart failure. African-Americans with heart failure usually have less access to health care services than Whites do; moreover, they are also faced with higher costs and a lower quality of care.

The Impact of Physiological Factors on 30-day Unplanned Rehospitalization in Adults with Heart Failure.

Heart failure (HF) patients have high rates of 30-day unplanned rehospitalization. This study assessed the impact of physiological factors on 30-day HF unplanned rehospitalization. METHODS: The cross-sectional study used secondary data from electronic medical records of 270 patients. RESULTS: Findings revealed several factor types were related to 30-day HF unplanned rehospitalization such as chronic kidney disease (p = 0.001), the use of CPAP machine (p = 0.028), and B-type natriuretic peptide (p = 0.050). CONCLUSION: Many physiological factors were associated with 30-day HF unplanned rehospitalization. Identifying these factors will help health care providers to plan a variety of interventions that reduce 30-day HF unplanned rehospitalization.
