Introduction: Standardized patient simulation can be an effective strategy to foster cultural competence education. Methodology: Guided by the Cultural Competence and Confidence Model, this grant-funded, longitudinal, one-group, pretest and posttest study used the Transcultural Self-Efficacy Tool (TSET) to examine the effect of the Diverse Standardized Patient Simulation (DSPS) cultural competence education strategy on students’ (n = 53) transcultural self-efficacy. Developed by following recommended guidelines and standards, the DSPS had content validity review. It aimed to improve students’ knowledge, skills, and attitudes with regard to providing culturally competent nursing care. The statistical methods included t-tests, McNemar’s test, correlation analyses, and Mann–Whitney U-test. Results: The DSPS influenced statistically significant changes (increase) in students’ transcultural self-efficacy perceptions (p <.05). All students regardless of background benefited from formalized cultural competence education. Discussion: Evidence-based strategies such as the DSPS can offer a valuable guide for educators to foster cultural competence education.

Abstract

Introduction: Smoking prevalence is high in Vietnam, yet tobacco dependence treatment (TDT) is not widely available. Methods: We conducted a quasiexperimental study that compared the effectiveness of health care provider advice and assistance (ARM 1) versus ARM 1 plus village health worker (VHW) counseling (ARM 2) on abstinence at 6-month follow-up. This study was embedded in a larger two-arm cluster randomized controlled trial conducted in 26 community health centers (CHCs) in Vietnam. Subjects (N = 1318) were adult patients who visited any participating CHC during the parent randomized controlled trial intervention period and were self-identified as current tobacco users (cigarettes and/or water pipe). Results: At 6-month follow-up, abstinences rates in ARM 2 were significantly higher than those in ARM 1 (25.7% vs. 10.5%; p <. 001). In multivariate analyses, smokers in ARM 2 were almost three times more likely to quit compared with those in ARM 1 (adjusted odds ratio [AOR] = 2.96, 95% confidence interval [CI] = 1.78% to 4.92%). Compared to cigarette-only smokers, water pipe-only smokers (AOR = 0.4, 95% CI = 0.26% to 0.62%) and dual users (AOR = 0.62, 95% CI = 0.45% to 0.86%) were less likely to achieve abstinence; however, the addition of VHW counseling (ARM 2) was associated with higher quit rates compared with ARM 1 alone for all smoker types. Conclusion: A team approach in TDT programs that offer a referral system for health care providers to refer smokers to VHW-led cessation counseling is a promising and potentially scalable model for increasing access to evidence-based TDT and increasing quit rates in low middle-income countries (LMICs). TDT programs may need to adapt interventions to improve outcomes for water pipe users. Implications: The study fills literature gaps on effective models for TDT in LMICs. The addition of VHW-led cessation counseling, available through a referral from primary care providers in CHCs in Vietnam, to health care provider's brief cessation advice, increased 6-month biochemically validated abstinence rates compared to provider advice alone. The study also demonstrated the potential effectiveness of VHW counseling on reducing water pipe use. For LMICs, TDT programs in primary care settings with a referral system to VHW-led cessation counseling might be a promising and potentially scalable model for increasing access to evidence-based treatment.

Abstract

Background: China has the world's largest aging population and the number of empty-nest older adults is on the rise. In comparison to the aging population in general, empty-nest older adults have a lower level of subjective well-being and poorer mental health status due to a lack of emotional support from their children. The aim of this study is to conduct an empirical study to evaluate the efficacy of the 'Path-oriented Psychological Self-help Intervention' (P-oPSI) led by nurses on the mental health of empty-nest older adults in the community, to provide a scientific foundation for improving their quality of life. Methods: A Quasi-Experimental controlled intervention study was conducted from 2015 to 2017. A total of 76 empty-nest older adults from 2 districts were recruited using a convenience sampling and assigned to 2 groups based on their residential communities in the city of Chifeng in the Inner Mongolia Autonomous Region, China. The wait list control group participated in a mental health lecture to gain knowledge and learn techniques of mental health promotion. The intervention group additionally received 1 month of training in a nurse-led 'P-oPSI' for a month. Both groups were followed-up for 3 months. Mental health status, coping styles, and psychological self-help ability of the participating empty nest older adults were assessed at the baseline, 1 month, and 3-months follow up, respectively. Two-way analysis of variance and a simple effect test were used to analyse the differences of the two groups. Results: The P-oPSI yielded a greater benefit for the mental health status, coping styles, and psychological self-help ability of the participants in the intervention group. Combined with a simple effect test, the scores of the mental health status, positive coping style, and psychological self-help ability of those in the intervention group significantly increased at 1 month after the baseline (F mental health status = 7.59, F positive coping style = 7.24, F psychological self-help ability = 7.07); and the sustainable effect of this program lasted for 3 months after the intervention (F mental health status = 13.24, F positive coping style = 10.42, F psychological self-help ability = 10.45), which reached statistical significance (P < 0.01). Conclusions: The P-oPSI program significantly improved the level of mental health of empty-nest older adults in China. This intervention provides a new approach of self-management to improve mental health of older adults in community settings. Trial registration: chictr.org.cn: ChiCTR1900025552.

Abstract

Purpose: Women with breast cancer report varying frequencies of cognitive problems during adjuvant systemic therapy. This variability suggests latent subgroups. Therefore, we identified latent subgroups of self-reported cognitive problems among postmenopausal women with and without breast cancer. We explored associations between membership in these subgroups and (a) demographic, clinical, and symptom characteristics and (b) variations in candidate gene polymorphisms. Methods: We evaluated frequency of cognitive problems using the Patient Assessment of Own Functioning Inventory. Growth mixture modeling identified latent subgroups over 18 months of adjuvant systemic therapy and at matched time points for women without cancer (N = 331). We evaluated for differences among subgroups in demographic, clinical, and symptom characteristics and in 41 single nucleotide polymorphisms in 10 candidate genes involved in DNA repair and oxidative stress pathways (n = 199). We modeled associations between genotypes and subgroup membership using multinomial logistic regression. Results: We identified three latent subgroups: more frequent, persistent, and almost never. Receipt of chemotherapy plus anastrozole, depressive symptoms, and baseline neuropathic symptoms increased the odds of belonging to the more frequent subgroup. Anxiety and depressive symptoms increased the odds of belonging to the persistent subgroup. With covariates controlled for, carrying the ERCC5 rs873601 G minor allele increased the odds of reporting more frequent cognitive problems. Conclusions: Chemotherapy plus anastrozole, depressive symptoms, and presence of neuropathic symptoms may predict more frequent cognitive problems during systemic therapy that later resolve. Mood dysregulation before therapy may predict persistent cognitive problems during therapy. ERCC5 genotype may influence frequency of cognitive problems after controlling for these risk factors.

Abstract

Background: Hypertension is the leading risk factor for mortality worldwide and is more common in sub-Saharan Africa than any other region. Work to date confirms that a lack of human and material resources for healthcare access contributes to this gap. The ways in which patients' knowledge and attitudes toward hypertension determine their engagement with and adherence to available care, however, remains unclear. Methods: We conducted an exploratory, qualitative descriptive study to assess awareness, knowledge, and attitudes towards hypertension and its management at a large private hospital in Kampala. We interviewed 64 participants (29 with hypertension and 34 without, 1 excluded) in English. General thematic analysis using the Integrated Conceptual Health Literacy Model was used to iteratively generate themes and categories. Results: We identified three main themes: Timing of Hypertension Diagnosis, Aiming for Health Literacy, and the Influence of Knowledge on Behavior. Most participants with hypertension learned of their condition incidentally, speaking to the lack of awareness of hypertension as an asymptomatic condition. Drove nearly all participants to desire more information. However, many struggled to translate knowledge into self-management behaviors due to incomplete information and conflicting desires of participants regarding lifestyle and treatment. Conclusions: Internal patient factors had a substantial impact on adherence, calling attention to the need for educational interventions. Systemic barriers such as cost still existed even for those with insurance and need to be recognized by treating providers.

Abstract

Background Patients treated for atrial fibrillation with an ablation can experience decreased mental health. Little is known about the effect of a psychoeducation intervention on this patient group. Objectives The aim of this study was to explore the effect of a psychoeducation intervention on patients' mental health after participating in a cardiac rehabilitation program, with a focus on elaborating on the lack of mental health improvements. Method Sequential explanatory mixed methods including secondary analysis of qualitative and quantitative data collected in a randomized rehabilitation trial was performed. Perceived health was measured by a questionnaire (n = 95), and qualitative interviews were performed (n = 10). Results Patients scoring high on perceived health experienced positive effects of the intervention. Patients scoring low appear to have either low physical capacity and severe atrial fibrillation symptoms, bigger life issues, or lack of social support. Conclusion: A more in-depth understanding of the effect of a psychoeducational intervention included in a cardiac rehabilitation program has been achieved.

Abstract

Objective: To examine the relationship of the symptoms of diarrhea and fatigue by testing a model that included multiple dimensions of the cancer-related-symptom experience. Methods: A secondary data analysis was conducted on data from the self-reports of 102 cancer patients co-experiencing diarrhea and fatigue during treatment at a comprehensive cancer center in the Southeastern United States. Structural equational modeling was employed to examine the relationship between the 2variables. Fatigue and diarrhea were assessed using items from the Cancer Symptom Scale. Results: The structural model results showed that (a) the model fit was adequate (b) diarrhea explained 7% of the variance in fatigue, and (c) the structural or path coefficient between diarrhea and fatigue was significant (0.267; p<0.05). Diarrhea had the strongest effect on fatigue interference (0.251). Conclusion: Diarrhea is a potential contributing factor to the symptom of fatigue and a potential target for interventions to prevent and ameliorate fatigue.

Abstract

OBJECTIVES:The primary objective was to investigate the prevalence and factors associated with elevated alcohol consumption among older adults 65 years and above in China and Norway. The secondary objective was to compare the prevalence and factors in the two countries.DESIGN:A secondary data analysis was conducted using two large cross-sectional studies (Chinese Longitudinal Healthy Longevity Survey data in 2008-2009 and Nord-Trøndelag Health Study data in 2006-2008).PARTICIPANTS:A total of 3223 (weighted) Chinese older adults and 6210 Norwegian older adults who responded drinking alcohol were included in the analysis.OUTCOME MEASURES:The dependent variable was elevated alcohol consumption, which was calculated as a ratio of those with elevated drinking among current drinkers. Multivariable logistic regression was used to test the dependent variable.RESULTS:The prevalence of elevated alcohol consumption among current drinkers for the Chinese and Norwegian samples were 78.3% (weighted) and 5.1%, respectively. Being male was related to a higher likelihood of elevated alcohol consumption in both Chinese and Norwegian samples (OR=2.729, 95% CI 2.124 to 3.506, OR=2.638, 95% CI 1.942 to 3.585). Being older, with higher levels of education and a living spouse or partner were less likely to have elevated drinking in the Chinese sample (OR=0.497, 95% CI 0.312 to 0.794, OR=0.411, 95% CI 0.260 to 0.649, OR=0.533, 95% CI 0.417 to 0.682, respectively). Among Norwegian older adults, a higher level of education was related to higher likelihood of elevated drinking (OR=1.503, 95% CI 1.092 to 2.069, OR=3.020, 95% CI 2.185 to 4.175). Living in rural areas and higher life satisfaction were related to lower likelihood of elevated drinking in the Norwegian sample (OR=0.739, 95% CI 0.554 to 0.984, OR=0.844, 95% CI 0.729 to 0.977, respectively).CONCLUSIONS:The elevated alcohol consumption patterns were strikingly different between China and Norway in regards to prevalence and socioeconomic distribution. To develop and implement culturally appropriate public health policies regarding alcohol in the future, public health policy makers and professionals need to be aware of the cultural differences and consider the demographic, social and economic characteristics of their intended population.

Abstract

Background Registered nurses are often underprepared with the knowledge and skills to care for hospitalized older adult patients. One strategy to bridge this gap is for hospitals to adopt the Nurses Improving Care for Healthsystem Elders (NICHE) program: A nurse-led interdisciplinary organizational intervention to improve care of hospitalized older adults. Objectives This study aimed to identify the market, organizational and managerial, and sociotechnical factors associated with the adoption of NICHE among U.S. hospitals in order to understand factors that promote and inhibit the adoption of models to improve care for elders and to provide a basis for future studies that evaluate the effects of NICHE participation on patient outcomes. Methods We used an observational, retrospective design, linking three national administrative data sources, in a secondary analysis. Data included the 2012-2013 American Hospital Association Annual Survey, NICHE database, and the American Nurses Credentialing Center Magnet database. Multivariate logistic regression models were completed at the hospital level (n = 3,506). Results Statistically significant variables associated with hospital adoption of the NICHE program include using a medical home model, being in a network, having a pain services program, being in an urban location, and having over 100 beds. Discussion Understanding factors that promote the adoption of organizational interventions like NICHE holds promise for accelerating the use of evidence-based clinical practices to promote health, function, and well-being for older hospitalized adults. Our results provide a foundation for assessing the effects of NICHE participation on patient outcomes by identifying factors that account for membership in NICHE.

Abstract

Failure to rescue refers to the inability to prevent death from health care complications. The fact that more than half of severe maternal morbidity and maternal deaths are classified as preventable, and black women have 2 to 3 times the risk for adjusted severe morbidity and maternal mortality suggest there is a problem with failure to rescue in US maternity care. This article reviews national efforts to improve rescue capacity in maternity care and data on communication breakdowns and disrespect in maternity care, and outlines individual and organizational actions that can be taken to improve communication and rescue processes.

Abstract

Background: Nurses can be exposed to hundreds of alarms during their shift, contributing to alarm fatigue. Purpose: The purposes were to explore similarities and differences in perceptions of clinical alarms by labor nurses caring for generally healthy women compared with perceptions of adult intensive care unit (ICU) and neonatal ICU nurses caring for critically ill patients and to seek nurses' suggestions for potential improvements. Methods: Nurses were asked via focus groups about the utility of clinical alarms from medical devices. Results: There was consensus that false alarms and too many devices generating alarms contributed to alarm fatigue, and most alarms lacked clinical relevance. Nurses identified certain types of alarms that they responded to immediately, but the vast majority of the alarms did not contribute to their clinical assessment or planned nursing care. Conclusions: Monitoring only those patients who need it and only those physiologic values that are warranted, based on patient condition, may decrease alarm burden.

Abstract

Background: Cardiovascular disease accounts for more than half of all deaths in the hemodialysis (HD) population. Although much of this mortality is associated with fluid overload (FO), FO is difficult to measure, and many HD patients have significant pulmonary congestion despite the absence of clinical presentation. Cohort studies have observed that FO, as measured by bioimpedance spectroscopy (BIS), correlates with mortality. Other studies have observed that lower sodium intake is associated with less fluid-related weight gain, improved hypertension, and survival. Whether sodium intake influences FO in HD patients as measured by BIS is not known. Objective: The aims of the study were to determine the feasibility of assessing the impact of sodium restriction on body fluid composition as measured by BIS among patients with three levels of sodium intake and to determine if there are statistical and/or clinical differences in BIS measures across sodium intake groups. Methods: We used a double-blinded randomized controlled trial design with three levels of sodium restriction, 2,400 mg per day, 1,500 mg per day, and unrestricted (control group), to test our aims. Forty-two HD patients from a tertiary acute care academic institution associated with three urban DaVita dialysis centers were enrolled. Participants remained in the inpatient center for 5 days and 4 nights and were randomly assigned to sodium intake groups. Body fluid composition was measured with BIS. Results: Recruitment, enrollment, and retention statistics supported the feasibility of the study design. Regression analyses showed that there were no statistically significant differences among sodium intake groups on any of the outcomes. Discussion: Our data suggest the need for additional research into the effects of sodium restriction on body fluid composition.

Abstract

Background We created the Measurement of Transitions in Cancer Scale to assess patients' perceptions of the extent of change they experience with cancer-related transitions and how well they feel they are managing these transitions. For some transitions, we found that the more change that was reported, the worse management was reported; however, the benchmark by which patients assess how well they have managed may vary with the extent of change. Objectives The aim of the study was to identify approaches to combine reports of extent and management of change. Methods Among women with breast cancer, we explored relationships of composite measures (arithmetic and geometric means, subtractive and proportional need for improvement) with other indicators of well-being (symptoms, anxiety, depression, uncertainty, self-efficacy, knowledge of care options, medical communication competence). We examined statistical significance using false rate discovery for multiple tests on correlations with clinical outcomes. Results Greater extent and less management were significantly associated with higher total symptoms, anxiety, depression, uncertainty, and less self-efficacy in Personal Transitions, but not in Care Transitions. The arithmetic and geometric means had weak correlations with clinical outcomes, whereas the subtractive and proportional need for improvement had significant correlations with most clinical outcomes both in Personal and Care Transitions. The combined proportional need for improvement in Personal Transitions was significantly associated with total symptoms, anxiety, depression, uncertainty, and self-efficacy. The Care Transitions score was also significantly associated with total symptoms, anxiety, uncertainty, and self-efficacy. Discussion These approaches can be applied to other aspects of self-management that require assessment of the extent and management of an experience. The four approaches yield different results. We recommend the need for improvement composites to capture correlations with the clinical outcomes.

Abstract

Objective: This study aims to examine gender differences in the association between migration and cognitive function among adults in China and India. Methods: Data from the World Health Organization Study on global AGEing and adult health (SAGE) study were used that included adults aged 50 + from China (N = 12,937) and India (N = 6244). Migration status included: urban residents, rural residents, urban-to-urban, rural-to-urban, rural-to-rural, and urban-to-rural migrants. Cognitive function was assessed by immediate and delayed recall tests, digit span tests, and verbal fluency test. Ordinary least square regression models were used to adjust for sociodemographic characteristics, psychosocial factors, health behaviors, and physical health status. Results: Controlling for multiple covariates, significant differences in cognitive function were found between men and women, and across migration groups. A consistent female disadvantage was found in China and India for cognitive function. Women who were rural residents or rural-to-rural migrants had the poorest cognitive function in both the Chinese and the Indian samples. Among males in China, rural residents had poorer cognitive function than urban residents, while urban-to-urban migrants had highest cognition scores; however, for male counterparts in India, rural-to-rural migrants had the poorest cognitive function. Conclusions: The results suggest that the association between migration and cognitive function differs by gender and country. In our study populations, major sociodemographic characteristics play a key role in accounting for the differences in cognitive function.

Abstract

Increase of peripheral blood CD4 lymphocyte counts is a key goal of combined antiretroviral therapy (cART); most, but not all, recipients respond adequately and promptly. A small number of studies have examined specific genetic factors associated with the extent of CD4 recovery. We report a genome-wide examination of factors that predict CD4 recovery in HIV-infected women. We identified women in in a cohort study who were on cART with viral load below 400 copies, and drew racially and ethnically matched samples of those with good CD4 response over 2 years or poor response. We analyzed the exomes of those women employing next generation sequencing for genes associated with CD4 recovery after controlling for non-genetic factors identified through forward stepwise selection as important. We studied 48 women with good CD4 recovery and 42 with poor CD4 recovery during virologically-suppressive cART. Stepwise logistic regression selected only age as a statistically significant (p<0.05) non-genetic predictor of response type (each additional year of age reduced the odds of good recovery by 11% (OR = 0.89, CI = 0.84–0.96, p = 0.0009). After adjustment for age and genomic estimates of race and ethnicity, 41 genes harbored variations associated with CD4 recovery group (p0.001); 5 of these have been previously reported to be associated with HIV infection, 4 genes would likely influence CD4 homeostasis, and 13 genes either had known functions or were members of product families that had functions for which interactions with HIV or effects on lymphocyte homeostasis were biologically plausible. Greater age was the strongest acquired factor that predicted poor CD4 cell recovery. Sequence variations spanning 41 genes were independently predictive of CD4 recovery. Many of these genes have functions that impact the cell cycle, apoptosis, lymphocyte migration, or have known interactions with HIV. These findings may help inform new hypotheses related to responses to HIV therapy and CD4 lymphocyte homeostasis.

Abstract

Maternal lipid profiles are associated with risk for preterm birth (PTB), although the lipid component and effect size are inconsistent between studies. It is also unclear whether these associations are the result of excessive changes in lipid metabolism during pregnancy or genetic variability in genes controlling basal lipid metabolism. This study investigates the association between genetic risk scores (GRS) for four lipid components (high-density lipoprotein [HDL-C], low-density lipoprotein [LDL-C], triacylglycerols [TAG], and total cholesterol [TC]) with risk for PTB. Subjects included 954 pregnant women from California for whom second trimester serum samples were available, of which 479 gave birth preterm and 475 gave birth at term. We genotyped 96 single-nucleotide polymorphisms, which were selected from genome-wide association studies of lipid levels in adult populations. Lipid-specific GRS were constructed for HDL-C, LDL-C, TAG, and TC. The associations between GRS and PTB were analyzed using logistic regression. A higher HDL-C GRS was associated with increased risk for PTB overall and spontaneous PTB. Higher TAG and TC GRS were associated with decreased risk for PTB overall and spontaneous PTB. This study identifies counter-intuitive associations between lipid GRS and spontaneous PTB. Further replication studies are needed to confirm these findings, but they suggest that our current scientific understanding of the relationship between lipid metabolism, PTB, and genetics is incomplete.

Abstract

Objective grocery transactions may reflect diet, but it is unclear whether the diet quality of grocery purchases mirrors geographic and racial/ethnic disparities in diet-related diseases. This cross-sectional analysis of 3961 households in the nationally representative Food Acquisition and Purchase Survey evaluated geographic and racial/ethnic disparities in grocery purchase quality. Respondents self-reported demographics and recorded purchases over 7 days; the Healthy Eating Index (HEI) 2015 assessed diet quality. Survey-weighted multivariable-adjusted regression determined whether there were geographic and racial/ethnic differences in HEI-15 scores. Respondents were, on average, 50.6 years, non-Hispanic white (NHW) (70.3%), female (70.2%), and had attended some college (57.8%). HEI-15 scores differed across geographic region (p < 0.05), with the highest scores in the West (57.0 ± 0.8) and lowest scores in the South (53.1 ± 0.8), and there was effect modification by race/ethnicity (p-interaction = 0.02). Regionally, there were diet disparities among NHW and non-Hispanic black (NHB) households; NHWs in the South had HEI-15 scores 3.2 points lower than NHWs in the West (p = 0.003). Southern NHB households had HEI-15 scores 8.1 points lower than Western NHB households (p = 0.013). Racial/ethnic disparities in total HEI-15 by region existed in the Midwest and South, where Hispanic households in the Midwest and South had significantly lower diet quality than NHW households. Heterogeneous disparities in the diet quality of grocery purchases by region and race/ethnicity necessitate tailored approaches to reduce diet-related disease.

Abstract

Background/Objectives: Somatization of depressive symptoms among Chinese American older adults remains understudied. This study aimed to identify whether the relationship between depressive symptoms and use of health services (ie, doctor visits, hospital, and emergency department) could be due to pain and whether acculturation played a role in the relations among depressive symptoms, pain, and health service use. Design and Participants: Secondary data came from the Population Study of Chinese Elderly in Chicago that surveyed 3159 Chinese community‐dwelling older adults in the greater Chicago area. The average age was 76.3 years (standard deviation = 8.4); 57.95% were female). Negative binominal models were used to identify the effects of depression and pain on each type of health service use, controlling for sociodemographics and health‐related factors (eg, chronic illness). Measurements: Depressive symptoms were assessed using the Patient Health Questionnaire‐9; pain was assessed by self‐reported pain severity. Participants were classified into low, moderate, and high acculturation groups based on acculturation scores.Results: Depressive symptoms and pain were positively related to health service use on the bivariate level. For groups with both low and high acculturation levels, depression and pain each independently predicted more health service use, whereas for the group with a moderate acculturation level, the effect of somatization was substantialized. Conclusion: Depression largely influenced health service use independently and partially through pain for older Chinese Americans. The somatization tended to be only salient for the moderate acculturation group, calling for more research attention to the complicated effect of acculturation.
