Background: Asian Americans are one of the fastest growing minority populations in the United States. With increases in the older adult population too, there needs to be research dedicated to their health. Past studies have shown that social isolation and loneliness predict greater physical, mental, and cognitive decline. This literature review was conducted to address this emerging need to understand the scope of research focused on social isolation and Asian American older adults. Methods: The PRISMA guidelines were used to guide this review. Four interdisciplinary databases searched were: PubMed, CINAHL, PsychINFO, and AgeLine. Search terms included variations on the words social isolation, loneliness, Asian Americans, and older adults. The date of the last search was July 6th, 2016. Articles were reviewed based on 5 eligibility criteria: (1) topic relevance, (2) study participants > 60 years of age, (3) Asian immigrants as main participants, (4) conducted in a Western country, and (5) published in the English language. The remaining studies were assessed on eight categories: ethnic group, health topic, geographic location, subject population, recruitment site, study design, outcomes accessed, and outcomes measures. Results: The search yielded 203 articles from the four databases. 49 articles were removed as duplicates. The 154 remaining studies were reviewed based on their abstract and 34 met the eligibility criteria and underwent full text review. Existing research has focused primarily on immigrant Chinese and Korean older adult populations located in major gateway cities (ex: Los Angeles, New York City). Studies were largely observational studies that were conducted using small community-based samples which makes generalizability difficult. There were zero interventional studies. Conclusions: There are critical gaps in the literature on social isolation in Asian immigrant populations. Future studies should prioritize health promotion intervention research and focus on diverse understudied Asian subgroups (e.g. South Asians, Cambodians, Filipinos). Potential pitfalls of this literature review include: accessing only four major databases, limiting searches to after 1995, and studies were conducted throughout countries with different healthcare systems

Geriatric syndromes are common in hospitalized elders with heart failure (HF), but association with clinical outcomes is not well characterized. The purpose of this study (N = 289) was to assess presence of geriatric syndromes using Joint Commission-mandated measures, the Braden Scale (BS) and Morse Fall Scale (MFS), and to explore prognostic utility in hospitalized HF patients. Data extracted from the electronic medical record included sociodemographics, medications, clinical data, comorbid conditions, and the BS and MFS. The primary outcome of mortality was assessed using Social Security Death Master File. Statistical analysis included Cox proportional hazards models to assess association between BS and MFS scores and all-cause mortality with adjustment for known clinical prognostic factors. Higher risk BS and MFS scores were common in hospitalized HF patients, but were not independent predictors of survival. Further study of the clinical utility of these scores and other measures of geriatric syndromes in HF is warranted.

Interdisciplinary care teams are important in managing older patients. Geriatric patients with cardiovascular problems represent a unique paradigm for interdisciplinary teams, and patients benefit from the assistance of physicians, nurses, social workers, pharmacists, and therapists collaborating on treatment plans. Teams work on the inpatient and outpatient sides and at patients' homes to maximize function and prevent readmissions to the hospital.

Older adults with multiple conditions receive care that is often fragmented, burdensome, and of unclear benefit. An advisory group of patients, caregivers, clinicians, health system engineers, health care system leaders, payers, and others identified three modifiable contributors to this fragmented, burdensome care: decision making and care focused on diseases, not patients; inadequate delineation of roles and responsibilities and accountability among clinicians; and lack of attention to what matters to patients and caregivers (ie, their health outcome goals and care preferences). The advisory group identified patient priority-directed care as a feasible, sustainable approach to addressing these modifiable factors.
