Mixed-Methods Study of Disability Self-Management in Mexican Americans With Osteoarthritis.

BACKGROUND: Health disparities in osteoarthritis (OA) outcomes exist both in the occurrence and treatment of functional limitation and disability for Mexican Americans. Although the effect of self-management of chronic illness is well established, studies demonstrate little attention to self-management of function or disability, despite the strong potential effect on both and, consequently, on patients' lives. OBJECTIVE: The purpose of this study pilot was to develop and test key variable relationships for a measure of disability self-management among Mexican Americans. METHODS: In this sequential, two-phased, mixed-methods, biobehavioral pilot study of Mexican American women and men with OA, a culturally tailored measure of disability self-management was created, and initial relationships among key variables were explored. RESULTS: First, a qualitative study of 19 adults of Mexican American descent born in Texas (United States) or Mexico was conducted. The Mexican American Disability Self-Management Scale was created using a descriptive content analysis of interview data. The scale was tested and refined, resulting in 18 items and a descriptive frequency of therapeutic management efforts. Second, correlations between study variables were estimated: Disability and function were negatively correlated. Disability correlated positively with social support and activity effort. Disability correlated negatively with disability self-management, pain, and C-reactive protein. Function was positively correlated with age, pain, and depression. Liver enzymes (alanine transaminase) correlated positively with pain and anxiety. DISCUSSION: This mixed-methods study indicates directions for further testing and interventions for disability outcomes among Mexican Americans.

Nurse-led web-based self-management program to improve patient activation and health outcomes in patients with chronic low back pain: an acceptability and feasibility pilot study.

BACKGROUND: Patients with chronic low back (cLBP) pain report reduced physical function and ability to participate in social roles and are more likely to use opioid pain medications. While self-management interventions have been shown to support these patients, their effectiveness has been limited due to poor patient engagement. "Patient activation" encompasses the skills, knowledge, and motivation that a person has to manage their health. Supporting patient activation may improve the effectiveness of self-management for cLBP. METHODS: In this single-masked pilot study of adults with cLBP, patients were randomized to receive either no intervention (control) or 6 weekly sessions of an evidence-based web-based self-management program (SMP) with or without health behavior change counseling (HBCC) using motivational interviewing. Participants were assessed at baseline and at 12 and 26 weeks using the Patient Activation Measure, Oswestry Disability Index and PROMIS physical function, social role participation, and pain interference. We assessed acceptability and feasibility based on recruitment, session attendance, and follow-up. RESULTS: Of 187 individuals screened, 105 were eligible and 34 were randomized to control (n = 12), SMP (n = 4), or SMP + HBCC (n = 18). The population had 19 women, 22 patients married or living with significant other, 13 Black or African American patients, and 4 Hispanic or Latino patients. Participants had a mean (SD) Oswestry Disability Index score of 42 (12), moderate impairments in physical function (40 (6.6)) and social roles (45 (10)), and moderately severe pain interference (61 (6.7)). Of 22 participants receiving SMP sessions, 20 participated in at least 1, 15 participated in at least 3, and 7 participated in all 6 sessions. Loss to follow-up was 6 over the 26-week study. Participants in the SMP and SMP + HBCC groups had at least medium effect size improvements in Patient Activation Measures and small-to-medium effect size improvements in Oswestry Disability Index scores and physical function and large effect size improvement in social roles at 12 weeks. Improvements persisted in the SMP + HBCC group at 26 weeks. CONCLUSIONS: A web-based SMP is acceptable and feasible in this population. Participants who received augmentation with HBCC had persistent improvements in health outcomes at 26 weeks. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT06236529 (2/1/2024 - retrospectively registered).

Evidence-based geriatric knowledge among healthcare providers in Vietnam: adaptation, validation, and pilot of the knowledge about older patients quiz.

BACKGROUND: Vietnam's aging population is growing rapidly, but its health workforce's capacity to provide quality geriatric care is not clearly understood. We aimed to provide a cross-culturally relevant and validated instrument to assess evidence-based geriatric knowledge among healthcare providers in Vietnam. METHODS: We translated the Knowledge about Older Patients Quiz from English to Vietnamese using cross-cultural adaptation methods. We validated the translated version by evaluating its relevance to the Vietnamese context, as well as its semantic and technical equivalence. We fielded the translated instrument on a pilot sample of healthcare providers in Hanoi, Vietnam. RESULTS: The Vietnamese Knowledge about Older Patients Quiz (VKOP-Q) had excellent content validity (S-CVI/Ave) and translation equivalence (TS-CVI/Ave) of 0.94 and 0.92, respectively. The average VKOP-Q score was 54.2% (95% CI: 52.5-55.8) and ranged from 33.3 to 73.3% among 110 healthcare providers in the pilot study. Healthcare providers in the pilot study had low scores on questions related to the physiopathology of geriatric conditions, communication techniques with sensory impaired older adults, and differentiating age related changes from abnormal changes or symptoms. CONCLUSIONS: The VKOP-Q is a validated instrument to assess geriatric knowledge among healthcare providers in Vietnam. The level of geriatric knowledge among healthcare providers in the pilot study was unsatisfactory, which supports the need for further assessment of geriatric knowledge among a nationally representative sample of healthcare providers.

Patient-centered care and geriatric knowledge translation among healthcare providers in Vietnam: translation and validation of the patient-centered care measure.

BACKGROUND: People are living longer, and the majority of aging people reside in low- and middle-income countries (LMICs). However, inappropriate healthcare contributes to health disparities between populations of aging people and leads to care dependency and social isolation. Tools to assess and evaluate the effectiveness of quality improvement interventions for geriatric care in LMICs are limited. The aim of this study was to provide a validated and culturally relevant instrument to assess patient-centered care in Vietnam, where the population of aging people is growing rapidly. METHODS: The Patient-Centered Care (PCC) measure was translated from English to Vietnamese using forward-backward method. The PCC measure grouped activities into sub-domains of holistic, collaborative, and responsive care. A bilingual expert panel rated the cross-cultural relevance and translation equivalence of the instrument. We calculated Content Validity Indexing (CVI) scores at both the item (I-CVI) and scale (S-CVI/Ave) levels to evaluate the relevance of the Vietnamese PCC (VPCC) measure to geriatric care in the Vietnamese context. We piloted the translated instrument VPCC measure with 112 healthcare providers in Hanoi, Vietnam. Multiple logistic regression models were specified to test the a priori null hypothesis that geriatric knowledge is not different among healthcare providers with perception of high implementation compared with low implementation of PCC measures. RESULTS: On the item level, all 20 questions had excellent validity ratings. The VPCC had excellent content validity (S-CVI/Ave of 0.96) and translation equivalence (TS- CVI/Ave of 0.94). In the pilot study, the highest-rated PCC elements were the holistic provision of information and collaborative care, while the lowest-rated elements were the holistic attendance to patients' needs and responsive care. Attention to the psychosocial needs of aging people and poor coordination of care within and beyond the health system were the lowest-rated PCC activities. After controlling for healthcare provider characteristics, the odds of the perception of high implementation of collaborative care were increased by 21% for each increase in geriatric knowledge score. We fail to reject the null hypotheses for holistic care, responsive care and PCC. CONCLUSION: The VPCC is a validated instrument that may be utilized to systemically evaluate the practice of patient-centered geriatric care in Vietnam.

The relationship between older adults' technology use, in-person engagement, and pandemic-related mental health.

OBJECTIVE: The objectives of this study are to 1) describe changes in in-person communication/activity and changes in older adult technology use during the COVID-19 pandemic and 2) examine whether less in-person communication/activity mediates the relationship between pandemic-related mental health and technology use. METHOD: Linear regressions (stratified by age and financial strain) and structural equation modeling were employed using a nationally representative, cross-sectional survey of 3,188 older adults from the 2020 National Health and Aging Trends Study's COVID-19 Questionairre. RESULTS: Older adults engaged in more technology-based activity (b = 0.24; p<.001), more technology-based health care communication (b = 0.22; p<.001), and more technology-based food acquisition (b = 0.21; p<.001) during the COVID-19 pandemic, as compared to before the pandemic. Results indicate that adults <80 years old demonstrated greater increases in technology-based activity, technology-based health communication, and technology-based food acquisition, compared to adults ≥80 years old. Change in in-person communication significantly mediated the relationship between pandemic-related mental health and technology-based communication (standardized coefficient= -0.012; p=.005), and change in in-person activity significantly mediated the relationship between pandemic-related mental health and technology-based activity (standardized coefficient= -0.017; p=.020). CONCLUSIONS: This study suggests that older adults are utilizing technology more, and therefore should be considered in technology design and dissemination. Technology use could be an important positive response to help those with pandemic related worries stay safely engaged with friends and family. Technologies should be produced that are modifiable for older adults with disabilities and affordable for older adults with fixed incomes.

The Context of Caregiving in Heart Failure: A Dyadic, Mixed Methods Analysis.

BACKGROUND: Caregiving for persons with heart failure (HF) varies based on the individual, family, and home contexts of the dyad, yet the dyadic context of HF caregiving is poorly understood. OBJECTIVE: The aim of this study was to explore dyadic perspectives on the context of caregiving for persons with HF. METHODS: Family caregivers and persons with HF completed surveys and semistructured interviews. Investigators also photographed caregiving areas to complement home environment data. Descriptive qualitative analysis resulted in 7 contextual domains, and each domain was rated as strength, need, or neutral. We grouped dyads by number of challenging domains of context, categorizing dyads as high (≥3 domains), moderate (1-2 domains), or minimal (0 domains) needs. Quantitative instruments included the 36-item Short Form Health Survey, ENRICHD Social Support, HF Symptom Severity, and Zarit Burden Interview. We applied the average score of each quantitative measure to the groups derived from the qualitative analysis to integrate data in a joint display. RESULTS: The most common strength was the dyadic relationship, and the most challenging domain was caregiving intensity. Every dyad had at least 2 domains of strengths. Of 12 dyads, high-needs dyads (n = 3) had the worst average score for 7 of 10 instruments including caregiver and patient factors. The moderate-needs dyads (n = 6) experienced the lowest caregiver social support and mental health, and the highest burden. CONCLUSION: Strengths and needs were evident in all patient-caregiver dyads with important distinctions in levels of need based on assessment of multiple contextual domains. Comprehensive dyadic and home assessments may improve understanding of unmet needs and improve intervention tailoring.

The Life-Course Perspectives of Mexican American Men With Mobility Limitation.

The life-history narratives of 10 Mexican American men with mobility limitations, age 55-77 years (mean = 63.8, SD = 5.8), were explored using a qualitatively driven, life-history mixed-methods study to understand perceptions of mobility limitations over the life course. Within that methodological and paradigmatic framework, conceptualizations of alterity and masculinity guided interpretation of data. Through an iterative, thematic analysis, we detail the way the men's lives were influenced by growing familial responsibility with age. Quantitative data were integrated into themes of narrative inheritance, family, and masculinity. It was posited that masculinity with mobility limitations shaped and was shaped by ethnic identity and responsibility. This has implications for understanding the experience of Mexican American men over the life course.

Barriers and facilitators to deprescribing before surgery: A qualitative study of providers and older adults.

INTRODUCTION: Deprescribing, the collaborative process between providers and patients to streamline medication regimen, may reduce the risk of adverse events following surgery among older adults with multimorbidity. However, barriers and facilitators to deprescribing for surgery has not been explored. METHODS: We conducted a qualitative study of Primary Care Providers (PCP) and patients aged 65 and older who were scheduled for surgery. We used the Theoretical Domains Framework, which informed the interview guide and analysis. RESULTS: A total of 16 participants (n=8 providers, n=8 patients) were included. Themes were regarding: 1) attitudes towards deprescribing before surgery, 2) perceived benefits of deprescribing before surgery, 3) patient-provider relationship and shared decision-making, 4) hope for surgery, 5) barriers to deprescribing before surgery, and 6) preferences for deprescribing follow-up. CONCLUSION: Our study findings regarding provider- and patient-related barriers and facilitators for deprescribing and desired processes before surgery may inform future deprescribing intervention targets before surgery.

Depressive Symptoms in Older African Immigrants with Mobility Limitations: A Descriptive Study.

OBJECTIVES: Before, during, and after their immigration to the United States, immigrants face stressful life circumstances that may render them at risk for depressive symptoms. However, there is a dearth of research on the mental health of African immigrants. We performed secondary data analyses of two studies in the Baltimore-Washington area to describe and identify correlates of depressive symptoms in older African immigrants. METHODS: Chi square tests, one-way ANOVAs, and linear regressions were used to describe and examine associations between depressive symptoms and immigrant-related risk factors. RESULTS: This sample included 148 participants who had a mean age of 62 (SD ± 8.2). Clinical depressive symptoms were present in 8.1% of participants, and trouble falling asleep for more than half of the days was the most prevalent symptom (20%). Levels of education, income, and migration reasons differed significantly from clinical depressive symptoms, but these were not significantly associated with more depressive symptoms after controlling for covariates. CONCLUSIONS: Longitudinal designs may further elucidate incidence, correlates, and long-term effects of depressive symptoms within this population. CLINICAL IMPLICATIONS: Knowledge of depressive symptom burden and risk factors can inform timely assessment, referral, and treatment of depressive symptoms and other mental health outcomes in older African immigrants.

Prevalence of functional limitations among foreign and US-born Black older adults: 2010-2016 National Health Interview Surveys.

OBJECTIVE: To determine whether the prevalence of functional limitations in United States (US) born differs from that of foreign-born Black older adults. DESIGN: We performed a cross-sectional analysis of data from 14,438 US-born and 1583 foreign-born Black older adults (≥50 years) in the 2010-2016 National Health Interview Surveys (NHIS). Functional limitations were defined by upper and lower extremity limitations, and global functional limitations. Generalized linear modeling using a Poisson distribution and logarithmic link function was used to compare the predicted probabilities of functional limitations in both groups. RESULTS: The mean age (SE) of US-born Blacks was 63.56 (0.12) years and foreign-born Blacks was 62.06 (0.32). The majority (92%) of foreign-born Blacks had resided in the US for ≥10 years. US-born older adults were more likely to have upper (46% vs. 29%, p < .001) and lower (61% vs. 40%, p < .001) extremity limitations than foreign-born Blacks. The prevalence of lower extremity limitations was 22% less in foreign-born Blacks compared to US-born Blacks after adjusting for sociodemographic and health profiles (Prevalence Ratio [PR]: 0.78, 95% CI:0.73-0.84). The adjusted prevalence of upper extremity limitations in foreign-born Blacks was 27% (PR: 0.73, 95% CI: [0.68-0.79]), compared to US-born Black older adults. And that of global functional limitations was 22% less (PR: 0.78, 95% CI [0.73-0.83]) in foreign-born compared to US-born Blacks. CONCLUSION: Compared to their US-born counterparts, foreign-born Black older adults had a markedly lower prevalence of upper and lower extremity functional limitations. Future comparative studies should examine reasons for this apparent health advantage among foreign-born adults to inform social and medical interventions to prevent functional decline in Black older adults in the US.

Promoting sleep in low-income older adults with disabilities: Comparing CAPABLE with a social engagement control.

Sleep plays a vital role in older adults' health. The Community Aging in Place-Advancing Better Living for Elders (CAPABLE) trial, conducted in Maryland between 2012 and 2016, is a 5-month biobehavioral environmental intervention study to reduce functional disabilities in 300 low-income older adults. Individual and environmental factors impacting sleep were addressed in CAPABLE. This secondary data analysis was to test the preliminary effect of CAPABLE on actigraph-measured sleep, compared with a social engagement control in 73 CAPABLE participants with pretest-posttest actigraph data. Participants in this analysis were aged 75.8±7.5 years; 86.3% of them were females and 84.9% were Black/African Americans. Both CAPABLE intervention and social engagement control improved sleep efficiency and reduced sleep onset latency. The effect of CAPABLE on sleep was comparable to social engagement. These findings underline the importance of promoting physical function and maintaining social activity for sleep in low-income older adults with disabilities.

Pain catastrophizing: A patient-centered approach to assessment.

ABSTRACT: Pain is a subjective experience and its perception and expression vary widely. Pain catastrophizing, which refers to patients' thoughts or feelings about their pain, may impact their communication of pain and nurses' subsequent response. This article discusses how nurses can more readily recognize, assess, and manage pain catastrophizing.

Testimonial Injustice: Linguistic Bias in the Medical Records of Black Patients and Women.

BACKGROUND: Black Americans and women report feeling doubted or dismissed by health professionals. OBJECTIVE: To identify linguistic mechanisms by which physicians communicate disbelief of patients in medical records and then to explore racial and gender differences in the use of such language. DESIGN: Cross-sectional. SETTING/PARTICIPANTS: All notes for patients seen in an academic ambulatory internal medicine practice in 2017. MAIN MEASURES: A content analysis of 600 clinic notes revealed three linguistic features suggesting disbelief: (1) quotes (e.g., had a "reaction" to the medication); (2) specific "judgment words" that suggest doubt (e.g., "claims" or "insists"); and (3) evidentials, a sentence construction in which patients' symptoms or experience is reported as hearsay. We used natural language processing to evaluate the prevalence of these features in the remaining notes and tested differences by race and gender, using mixed-effects regression to account for clustering of notes within patients and providers. KEY RESULTS: Our sample included 9251 notes written by 165 physicians about 3374 unique patients. Most patients were identified as Black (74%) and female (58%). Notes written about Black patients had higher odds of containing at least one quote (OR 1.48, 95% CI 1.20-1.83) and at least one judgment word (OR 1.25, 95% CI 1.02-1.53), and used more evidentials (ß 0.32, 95% CI 0.17-0.47), compared to notes of White patients. Notes about female vs. male patients did not differ in terms of judgment words or evidentials but had a higher odds of containing at least one quote (OR 1.22, 95% CI 1.05-1.44). CONCLUSIONS: Black patients may be subject to systematic bias in physicians' perceptions of their credibility, a form of testimonial injustice. This is another potential mechanism for racial disparities in healthcare quality that should be further investigated and addressed.

Community-dwelling older adults who are low-income and disabled weathering financial challenges.

Despite interventions aiming to improve outcomes among older adults experiencing financial challenges, the challenges and strategies employed to handle them are poorly understood. This study examined the experiences of financial challenges among low-income adults aged ≥65 years. Eleven semi-structured interviews were analyzed using thematic analyses. An overarching theme was "I guess it balances", capturing attempts to maintain hope and proactively address challenges despite stress, uncertainty and limitations. Balancing was demonstrated within four domains, including cognitive bandwidth ("think a lot" versus "I don't dwell on that"), emotional experience ("depressing" versus "be thankful"), learned resilience ("that was a shock" versus "there's always a way"), and meeting daily needs ("we learned to do without" versus "take a dollar and stretch it"). Participants described being weathered by challenges and using predominately high-effort coping strategies to weather the challenges. These findings call for strengthening the safety net for older adults facing financial challenges.

Home/community-based interventions to improve function in persons with mild cognitive impairment/early dementia.

Persons with mild cognitive impairment/early dementia have a possible 20-year trajectory of disability and dependence with little information on the effectiveness of interventions to improve function. This review investigates the literature of home/community-based interventions for physical and executive function in persons with mild cognitive impairment/early dementia. A 2007-2020 systematic literature search was conducted through PubMed, CINAHL Plus with Full Text and PsycINFO. Of the 1749 articles retrieved, 18 eligible studies were identified and consisted of three types of interventions: cognitive training-only (n = 7), multicomponent (n = 9), and physical activity-only (n = 2). Results showed that the interventions impacting function in persons with cognitive impairment incorporated a visual/written element, technology-based training, caregiver support, and modified duration/increased frequency of interventions. In studies improving function, participants simulated Instrumental Activities of Daily Living. They addressed cognitive function using both objective and subjective cognitive measures. We found gaps in the literature in incorporating race/ethnicity and appropriate socioeconomic status measures.

"All I know is that there is a lot of discrimination": Older African immigrants' experiences of discrimination in the United States.

Discrimination is implicated in the disproportionate burden of disease and health disparities in racial/ethnic minorities. This qualitative descriptive study explored the experiences of discrimination and its impact on the health of older African immigrants. Semi-structured interviews were conducted with 15 participants. Three main themes and six sub-themes were identified. These included: (1) types of discrimination which were: (a) accent-based, (b) unfair treatment during routine activities, (c) experience with systems; (2) consequences of discrimination; and (3) surviving and thriving with discrimination: (a) "blind eye to it", (b) reacting to it, (c) avoiding it. These themes described common experiences of discrimination, current strategies used to deal with discrimination, and the impact of discrimination on this sample. Health care providers should be aware of discrimination experiences, how to assess for it, and identify when to refer patients to appropriate community resources that include mental health, employment, cultural groups and legal services.

Pain in persons with dementia and the direct and indirect impacts on caregiver burden.

OBJECTIVES: Unresolved pain is related to neuropsychiatric symptoms (NPS) in persons living with dementia (PLWD), and an increase in NPS is distressing for PLWD and their caregivers. Hence, we examined whether pain in PLWD was related to caregiver burden and whether caregiver upset with NPS mediated this relationship. METHOD: We examined, cross-sectionally, the relationships among pain in PLWD, caregiver burden, and upset with NPS. Data from 272 PLWD and their caregivers who participated in the Advancing Caregiver Training (ACT) trial were analyzed using structural equation modeling (SEM). RESULTS: Model fit was satisfactory, and caregiver upset with NPS fully mediated the association between pain in PLWD and caregiver burden. CONCLUSION: Caregiver upset with NPS helps explain the relationship between pain in PLWD and burden in their caregivers. Pain and NPS are amenable to modification, as is caregiver burden, suggesting great opportunity to impact the lives of PLWD and their caregivers.

Quality and Quantity of Social Support Show Differential Associations With Stress and Depression in African Americans.

Social support (SS) is typically associated with lower emotional distress (e.g., stress and depression) in individuals. However, SS is a multifaceted construct that can vary by quality, quantity (amount), and type (i.e., it can be emotional or instrumental in nature). OBJECTIVE: The current study examined the relationships between characteristics of SS, stress, and depression in aging African Americans. PARTICIPANTS: Analyses focused on data from 705 participants aged 22-92 years from the Carolina African American Twin Study of Aging. MEASUREMENTS: Measures included the quality and quantity of emotional and instrumental support received, as well as stress and depression. DESIGN: A series of univariate and increasingly complex multivariate regression models were conducted in MPlus (using the cluster option to control for family structure) to examine the relationships between SS and emotional distress variables. RESULTS: Overall, better quality of emotional SS predicted fewer depression symptoms and less perceived stress, after controlling for age, gender, socioeconomic status variables, and the other subtypes of SS. However, more instances of emotional SS were associated with higher levels of perceived stress, depression symptoms, and more stressful life events within the past year. Likewise, more instrumental SS predicted more perceived stress, while holding the other variables constant. CONCLUSION: African Americans who experience more emotional distress report more SS, but the quality of emotional support appears to play an important role in the association between reduced levels of stress and depression. These findings suggest that interventions should include approaches to reduce emotional distress as well as enhance the quality SS.

Distinct clusters of older adults with common neuropsychological symptoms: Findings from the National Health and Aging Trends Study.

This study aims to identify distinct clusters of community-dwelling older adults (N = 7580) based on characteristics of common neuropsychological symptoms and examine how these clusters differ in socio-demographics and health-related attributes. Four clusters were identified: 1-No Symptoms (41%), 2-Pain Only (32%), 3-Pain+Moderate+Insomnia+Mild Depression+Mild Anxiety (17%), and 4-Pain+Mild insomnia+Moderate Depression+Moderate Anxiety (10%). Compared to clusters 1 and 2, individuals in clusters 3 and 4 tended to be older, Hispanic or non-Hispanic Black, female, obese, have high school education or less, not live with anyone, and rate their health fair or poor. Compared to cluster 1, others were significantly associated with worse health-related attributes. This association was distinctly stronger in clusters with more symptoms that were more severe. Interventions focusing on pain may need to incorporate strategies to deal with sleep and psychological symptoms and the severity to improve associated health-related attributes and reduce health care burden.
