Abstract

Objective Adverse outcomes associated with chronic depressive symptoms are of clinical importance. The objective was to identify subgroups of older adults based on their trajectories of depressive symptoms over a 10-year period and determine if these subgroups predicted oral health outcomes. Methods The sample was 944 adults aged 65+ who participated in the oral health module of the the Health and Retirement Survey in 2008. Depressive symptoms were measured with a modified version of the Center for Epidemiologic Studies-Depression (CES-D) scale. Latent class trajectory analysis was used to identify distinct subgroups of elders based on their CES-D scores from 1998-2008. Group membership was used to predict self-rated oral health, overall mouth condition (problems with bleeding gums, gum sensitivity, and food avoidance), and edentulism in 2008. Results Three distinct subgroups were identified using zero-inflated Poisson regression models: (i) minimal depressive symptoms over the study period (43%), (ii) low but generally stable level of depressive symptoms (41%), and (iii) moderate symptoms and higher CES-D scores than the other groups over the 10 years (16%). Controlling for demographic and health variables and edentulism status, having a trajectory of moderate symptoms was associated with poorer mouth condition (p < 0.0001) and poorer self-rated oral health (p = 0.0003) compared with those with minimal symptoms. Having low levels of depressive symptoms was not significantly associated with these two outcomes. Group membership was not significantly associated with the probability of edentulism. Conclusions Chronic moderate depressive symptoms are associated with poorer oral health in older adults.

Abstract

Objectives: While trends in tooth loss among older adults have been well documented and show a decline over the last few decades, little is known about trends in tooth decay which may lead to tooth loss. The study aim was to examine trends in tooth decay among adults ages 50 years and older in the United States and determine whether these trends were consistent across demographic and socioeconomic subgroups of middle-aged and older adults. Methods: Secondary analysis of data collected through detailed oral health examinations in the National Health and Nutrition Examination (NHANES) surveys 1988–1994 and 1999–2004. Tooth decay was measured as active caries. Multivariable associations were estimated using negative binomial regression models. Results: Averaged over time, the mean number of decayed teeth was 0.54. Rates of decay remained stable over time. Males, non-Hispanic Blacks, Mexican-Americans, and those of other race/ethnicity as well as those with fewer years of education and lower levels of income had more decayed teeth. The increased number of decayed teeth for Mexican-Americans and those of other race/ethnicity was due in part to differing levels of education and income. Trends over time did not vary by any of these demographic and socioeconomic characteristics. Trends in the number of decayed teeth did not meaningfully change when the numbers of missing and filled teeth were controlled. Conclusions: Although studies have shown the number of middle-aged and older Americans experiencing tooth loss has decreased over time, trends in tooth decay have remained relatively stable, with socioeconomic disparities persisting over time.

Abstract

Background and Aims: To address barriers to implementing the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) in medical settings, we adapted the traditional interviewer-administered (IA) ASSIST to an audio-guided computer assisted self-interview (ACASI) format. This study sought to validate the ACASI ASSIST by estimating the concordance, correlation and agreement of scores generated using the ACASI versus the reference standard IA ASSIST. Secondary aims were to assess feasibility and compare ASSIST self-report to drug testing results. Design: Participants completed the ACASI and IA ASSIST in a randomly assigned order, followed by drug testing. Setting: Urban safety-net primary care clinic in New York City, USA. Participants: A total of 393 adult patients. Measurements: Scores generated by the ACASI and IA ASSIST; drug testing results from saliva and hair samples. Findings: Concordance between the ACASI and IA ASSIST in identifying moderate-high-risk use was 92-99% for each substance class. Correlation was excellent for global scores [intraclass correlation (ICC)=0.937, confidence interval (CI)=0.924-0.948] and for substance-specific scores for tobacco (ICC=0.927, CI=0.912-0.940), alcohol (ICC=0.912, CI=0.893-0.927) and illicit drugs (ICC=0.854, CI=0.854-0.900) and good for prescription drugs (ICC=0.676, CI=0.613-0.729). Ninety-four per cent of differences in global scores fell within anticipated limits of agreement. Among participants with a positive saliva test, 74% self-reported use on the ACASI ASSIST. The ACASI ASSIST required a median time of 3.7minutes (range 0.7-15.4), and 21 (5.3%) participants requested assistance. Conclusions: The computer self-administered Alcohol, Smoking and Substance Involvement Screening Test appears to be a valid alternative to the interviewer-administered approach for identifying substance use in primary care patients.

Abstract

Objectives: The objective of this study was to determine the relationship of serum vitamin D deficiency (VDD) to histologic features of non-alcoholic fatty liver disease (NAFLD), and associated demographic, clinical, laboratory, and transcriptomic data in the well-characterized Non-alcoholic Steatohepatitis Clinical Research Network (NASH CRN) cohort. METHODS: Serum vitamin D 25(OH)D (VD) was quantified by liquid chromatography-tandem mass spectrometry in 190 adults (>18 years) with biopsy-proven NAFLD. Subjects were categorized according to their level of VD as either sufficient (>30 ng/ml), insufficient (≥20≤30 ng/ml), or deficient (VDD; <20 ng/ml). Multivariable logistic regression was used to investigate the association of VDD and the presence of definite NASH and individual histological features of NAFLD after adjusting for age, sex, race, body mass index, alanine aminotransferase, and diabetes status. Hepatic transcriptomic data was compared between VDD and non-VDD subjects. Results: VDD was present in 55% of subjects and was independently associated with definitive NASH (odds ratio (OR) 3.15, 95% confidence interval (CI), 1.62-6.15, P=0.001), increased lobular inflammation (OR=1.98, 95% CI, 1.08-3.61, P=0.026), more ballooning (OR=2.38, 95% CI, 1.32-4.30, P=0.004), and the presence of fibrosis (OR=2.32, 95% CI, 1.13-4.77, P=0.022). There was a significant inverse relationship between lower levels of serum resistin and increased VD level category (P=0.013). The KRT10, SEMA3B, SNORD3C, ARSD, and IGKV4-1 genes were differentially expressed (false discovery rate <0.05) between VDD and non-VDD subjects. Gene ontology and pathway analysis suggest activation of the mitogen-activated protein kinase and nuclear factor-κB pathways in VDD NAFLD subjects. Conclusions: VDD is prevalent among US adult NAFLD patients and is independently associated with a definitive diagnosis of NASH and increased histological severity. Novel associations in proinflammatory pathways were identified, which suggest the mechanism for VDD in the pathogenesis of NASH and support dietary and/or lifestyle modifications to increase vitamin D levels in these patients.

Abstract

Introduction: Cardiovascular disease has been identified as the leading cause of maternal mortality in the United States, with cardiomyopathy, including peripartum cardiomyopathy (PPCM), accounting for 12% to 16% of all pregnancy-related deaths. The purpose of this study was to describe women's experiences being diagnosed with PPCM. Methods: This investigation was conducted using a qualitative design. We collected publicly available narratives posted by 92 women with PPCM (mean [SD] age 29 [6] years, mean [SD] ejection fraction 25.5 [10.8]%) in 3 online support groups. Data were coded and thematically organized so as to produce a richly detailed account of this experience. Results: The experience of diagnosis was marked by the women's distinct memories of their initial symptoms and whether they were dismissed or taken seriously. The most commonly reported symptoms were extreme shortness of breath, orthopnea, tachycardia, palpitations, chest pain, cough, and edema. Nearly 40% of women experienced symptom dismissal by health care providers. One-fourth of women were initially given inaccurate diagnoses ranging from “new mom anxiety” to asthma. Women described their initial reaction to diagnosis as feeling terrified, devastated, and feeling a sense of doom. Women had difficulty caring for their newborns during the postpartum period, and they struggled with the medical advice they received to not get pregnant again. Discussion: Despite experiencing severe subjective and objective symptoms, nearly 40% of women with PPCM experienced symptom dismissal by health care providers, in part due to the overlap between normal symptoms of pregnancy or the postpartum period and symptoms of heart failure.

Abstract

The purpose of the current study was to explore how Minimum Data Set (MDS) coordinators perceive their role and the assessment process. Eleven MDS coordinators from 10 geographically dispersed nursing homes (NHs) were interviewed between May and September 2013. Four broad themes emerged from content analysis: (a) information gathering, (b) interdisciplinary coordination, (c) role challenges, and (d) resources. The fi rst two themes referred to key components and competencies in the MDS coordinators' role, the third theme dealt with certain challenges inherent in the role, and the fourth theme highlighted resources that helped address these challenges. The current study provides insight into how MDS coordinators perceive their role, as well as some of the challenges they face to successfully enact that role. The current fi ndings can help inform NH management staff, such as directors of nursing and NH administrators, and policy makers, on how best to support MDS coordinators' work to enable effi cient and accurate resident assessment processes.

Abstract

Physical activity and cardiac rehabilitation (CR) are components of heart failure (HF) self-care. The aims of this study were to describe patterns of physical activity in African Americans (n = 30) with HF and to explore experience in CR. This was a mixed method, concurrent nested, predominantly qualitative study. Qualitative data were collected via interviews exploring typical physical activity, and CR experience. It was augmented by quantitative data measuring HF severity, self-care, functional capacity and depressive symptoms. Mean age was 60 ± 15 years; 65% were New York Heart Association (NYHA) class III HF. Forty-three percent reported that they did less than 30 min of exercise in the past week; 23% were told “nothing” about exercise by their provider, and 53% were told to do “minimal exercise”. A measure of functional capacity indicated the ability to do moderate activity. Two related themes stemmed from the narratives describing current physical activity: “given up” and “still trying”. Six participants recalled referral to CR with one person participating. There was high concordance between qualitative and quantitative data, and evidence that depression may play a role in low levels of physical activity. Findings highlight the need for strategies to increase adherence to current physical activity guidelines in this older minority population with HF.

Abstract

Background Substance use screening is widely encouraged in health care settings, but the lack of a screening approach that fits easily into clinical workflows has restricted its broad implementation. The Substance Use Brief Screen (SUBS) was developed as a brief, self-administered instrument to identify unhealthy use of tobacco, alcohol, illicit drugs, and prescription drugs. We evaluated the validity and test-retest reliability of the SUBS in adult primary care patients. Methods Adults aged 18-65 years were enrolled from urban safety net primary care clinics to self-administer the SUBS using touch-screen tablet computers for a test-retest reliability study (n = 54) and a 2-site validation study (n = 586). In the test-retest reliability study, the SUBS was administered twice within a 2-week period. In the validation study, the SUBS was compared with reference standard measures, including self-reported measures and oral fluid drug tests. We measured test-retest reliability and diagnostic accuracy of the SUBS for detection of unhealthy use and substance use disorder for tobacco, alcohol, and drugs (illicit and prescription drug misuse). Results Test-retest reliability was good or excellent for each substance class. For detection of unhealthy use, the SUBS had sensitivity and specificity of 97.8% (95% confidence interval [CI], 93.7-99.5) and 95.7% (95% CI, 92.4-97.8), respectively, for tobacco; and 85.2% (95% CI, 79.3-89.9) and 77.0% (95% CI, 72.6-81.1) for alcohol. For unhealthy use of illicit or prescription drugs, sensitivity was 82.5% (95% CI, 75.7-88.0) and specificity 91.1% (95% CI, 87.9-93.6). With respect to identifying a substance use disorder, the SUBS had sensitivity and specificity of 100.0% (95% CI, 92.7-100.0) and 72.1% (95% CI, 67.1-76.8) for tobacco; 93.5% (95% CI, 85.5-97.9) and 64.6% (95% CI, 60.2-68.7) for alcohol; and 85.7% (95% CI, 77.2-92.0) and 82.0% (95% CI, 78.2-85.3) for drugs. Analyses of area under the receiver operating curve (AUC) indicated good discrimination (AUC 0.74-0.97) for all substance classes. Assistance in completing the SUBS was requested by 11% of participants. Conclusions The SUBS was feasible for self-administration and generated valid results in a diverse primary care patient population. The 4-item SUBS can be recommended for primary care settings that are seeking to implement substance use screening.

Abstract

AIM This article assesses the knowledge of faculty in baccalaureate nursing programs and their readiness to teach about lesbian, gay, bisexual, and transgender (LGBT) health. BACKGROUND Although health disparities affecting the LGBT population are increasingly acknowledged in the literature, a dearth of information exists on how LGBT health is integrated in nursing programs. METHOD A survey was sent to a nonprobability purposive sample of nursing school administrative leaders (A/=739); they were asked to share the link with their faculty. More than 1, 000 faculty completed the survey. RESULTS The knowledge, experience, and readiness for teaching LGBT health among baccalaureate faculty are limited. LGBT faculty reported greater awareness, knowledge, and readiness compared with heterosexual faculty. The estimated median time devoted to teaching LGBT health was 2.12 hours. CONCLUSION Findings will help inform the design of faculty development programs and guide in aligning the curricula with current LGBT health priorities.

Abstract

Background: Research on self- and family management of chronic conditions has advanced over the past 6 years, but the use of simple frameworks has hampered the understanding of the complexities involved. Purpose: We sought to update our previously published model with new empirical, synthetic, and theoretical work. Methods: We used synthesis of previous studies to update the framework. Discussion: We propose a revised framework that clarifies facilitators and barriers, processes, proximal outcomes, and distal outcomes of self- and family management and their relationships. Conclusions: We offer the revised framework as a model that can be used in studies aimed at advancing self- and family management science. The use of the framework to guide studies would allow for the design of studies that can address more clearly how self-management interventions work and under what conditions.

Abstract

Background: Key predictors of early career nurses' turnover are job satisfaction, organizational commitment, job search, intent to stay, and shock (back injuries) based on the literature review and our previous research. Existing research has often omitted one of these key predictors. Objectives: The purpose of this study in a sample of early career nurses was to compare predictors of turnover to nurses' actual turnover at two time points in their careers. Design: A multi-state longitudinal panel survey of early career nurses was used to compare a turnover model across two time periods. The sample has been surveyed five times.Participants: The sample was selected using a two-stage sample of registered nurses nested in 51 metropolitan areas and nine non-metropolitan, rural areas in 34 states and the District of Columbia. Methods: The associations between key predictors of turnover were tested using structural equation modeling and data from the earliest and latest panels in our study. We used predictors from the respondents who replied to the Wave-1 survey in 2006 and their turnover status from Wave 2 in 2007 (N = 2386). We compared these results to the remaining respondents' predictors from Wave 4 in 2011 and their turnover status in Wave 5 in 2013 (N = 1073). We tested and found no effect for missingness from Wave 1-5 and little evidence of attrition bias. Results: Strong support was found for the relationships hypothesized among job satisfaction, organizational commitment, intent to stay, and turnover, with some support for shock and search in the Wave 1-2 sample. However, for Wave 4-5 sample (n = 1073), none of the paths through search were significant, nor was the path from shock to turnover. Conclusions: Nurses in the second analysis who had matured longer in their career did not have a significant response to search or shock (back injuries), which may indicate how easily experienced registered nurses find new jobs and/or accommodation to jobs requiring significant physicality. Nurse turnover is a major concern for healthcare organizations because of its costs and related outcomes. The relevant strength and relationships of these key turnover predictors will be informative to employers for prioritizing strategies to retain their registered nurse workforce. We need more research on programs that implement changes in the work environment that impact these two outcomes, as well as research that focuses on the relevant strength or impact to help administrators prioritize translation of results.

Abstract

Purpose In the United States, the prevalence of the use of alternative tobacco products (ATPs) (e.g., hookahs, e-cigarettes, cigars/cigarillos) has increased sharply. As future health care providers, medical students will play a critical role in health promotion and disease prevention. This study investigated medical students' use, knowledge, and beliefs about cigarettes and ATPs. Method In 2014, the authors surveyed all students enrolled at one medical school in New York City. The survey included questions about personal use of tobacco products, perceptions about the harms of ATPs and their role in disease causation, education about ATPs, and cessation training and practices related to ATPs and cigarettes. The authors compared results across medical school classes. Results Of 720 students, 431 (59.9%) completed the survey. Of those, 64 (14.7%) were current users of tobacco or smoking products, including cigarettes (17; 3.9%), ATPs (21; 4.8%), or marijuana (39; 8.9%). Many believed that ATPs contributed less than cigarettes to various diseases. Respondents received less cessation training regarding ATPs than cigarettes (P <.0001). They felt less confident providing ATP cessation counseling than cigarette cessation counseling (P <.0001) and were less likely to report counseling patients on ATP cessation than cigarette cessation (46 [10.7%] versus 280 [64.8%], P <.0001). Conclusions A concerning percentage of surveyed medical students use tobacco products, including ATPs, and lack the knowledge, education, and cessation counseling skills to provide accurate information about them to patients. ATP education should be added to medical school curricula to address this gap.

Abstract

Background: Shortages of health workers and large number of HIV-infected persons in Africa mean that time to provide antiretroviral therapy (ART) adherence and other messages to patients is limited. Methods: Using time-motion methodology, we documented the intensity and nature of counseling delivered to patients. The study was conducted at a rural and an urban HIV clinic in western Kenya. We recorded all activities of 190 adult patients on ART during their return clinic visits to assess type, frequency, and duration of counseling messages. Results: Mean visit length for patients at the rural clinic was 44.5 (SD = 27.9) minutes and at urban clinic was 78.2 (SD = 42.1) minutes. Median time spent receiving any counseling during a visit was 4.07 minutes [interquartile range (IQR), 1.57-7.33] at rural and 3.99 (IQR, 2.87-6.25) minutes at urban, representing 11% and 8% of total mean visit time, respectively. Median time patients received ART adherence counseling was 1.29 (IQR, 0.77-2.83) minutes at rural and 1.76 (IQR, 1.23-2.83) minutes at urban (P = 0.001 for difference). Patients received a median time of 0.18 (0- 0.72) minutes at rural and 0.28 (IQR, 0-0.67) minutes at urban clinic of counseling regarding contraception and pregnancy. Most patients in the study did not receive any counseling regarding alcohol/ substance use, emerging risks for ongoing HIV transmission. Conclusions: Although ART adherence was discussed with most patients, time was limited. Reproductive counseling was provided to only half of the patients, and "positive prevention" messaging was minimal. There are strategic opportunities to enhance counseling and information received by clients within HIV programs in resource-limited settings.

Abstract

Background: Although urinary incontinence is prevalent among older women living in rural Korea, a lack of awareness and education exists in this population and among health professionals. Geographic isolation and limited resources also contribute to having few educational offerings for rural nurses. The authors’ aim was to develop an online continuing education course on continence care for community health nurses and to examine its effectiveness. Method: A one-group, pretest–posttest design was used to detect changes in knowledge and attitudes after taking the online education course. Participant satisfaction was also measured at the end of the training. Results: A signifi cant improvement in knowledge and attitudes toward continence care was noted. More than 95% of participants responded that they would recommend the online program to other health care providers and indicated the program would be helpful regarding continence care in their practice. Conclusion: The continuing education online course is a feasible strategy to support rural community health nurses’ learning to improve knowledge and attitudes toward urinary incontinence management and care.

Abstract

We propose the Adaptive Leadership Framework for Chronic Illness as a novel framework for conceptualizing, studying, and providing care. This framework is an application of the Adaptive Leadership Framework developed by Heifetz and colleagues for business. Our framework views health care as a complex adaptive system and addresses the intersection at which people with chronic illness interface with the care system. We shift focus from symptoms to symptoms and the challenges they pose for patients/families. We describe how providers and patients/families might collaborate to create shared meaning of symptoms and challenges to coproduce appropriate approaches to care.
