Determinants of health after hospital discharge: rationale and design of the Vanderbilt Inpatient Cohort Study (VICS)

Leveraging home health aides to improve outcomes in heart failure: A pilot study protocol

Heart failure (HF) affects six million people in the U.S., is associated with high morbidity, mortality, and healthcare utilization.(1, 2) Despite a decade of innovation, the majority of interventions aimed at reducing hospitalization and readmissions in HF have not been successful.(3-7) One reason may be that most have overlooked the role of home health aides and attendants (HHAs), who are often highly involved in HF care.(8-13) Despite their contributions, studies have found that HHAs lack specific HF training and have difficulty reaching their nursing supervisors when they need urgent help with their patients. Here we describe the protocol for a pilot randomized control trial (pRCT) assessing a novel stakeholder-engaged intervention that provides HHAs with a) HF training (enhanced usual care arm) and b) HF training plus a mobile health application that allows them to chat with a nurse in real-time (intervention arm). In collaboration with the VNS Health of New York, NY, we will conduct a single-site parallel arm pRCT with 104 participants (HHAs) to evaluate the feasibility, acceptability, and effectiveness (primary outcomes: HF knowledge; HF caregiving self-efficacy) of the intervention among HHAs caring for HF patients. We hypothesize that educating and better integrating HHAs into the care team can improve their ability to provide support for patients and outcomes for HF patients as well (exploratory outcomes include hospitalization, emergency department visits, and readmission). This study offers a novel and potentially scalable way to leverage the HHA workforce and improve the outcomes of the patients for whom they care. Clinical trial.gov registration: NCT04239911.

Medication Discrepancies among Older Hospitalized Adults Discharged from Post-Acute Care Facilities to Home

OBJECTIVES

The epidemiology of medication discrepancies during transitions from post-acute care (PAC) to home is poorly described. We sought to describe the frequency and types of medication discrepancies among hospitalized older adults transitioning from PAC to home.

DESIGN

A nested cohort analysis.

SETTING AND PARTICIPANTS

Included participants enrolled in a patient-centered deprescribing trial, for patients (aged ≥50 years and taking at least 5 medications) transitioning from one of 22 PACs to home.

METHODS

We assessed demographic and medication measures at the initial hospitalization. The primary outcome measure was medication discrepancies, with the PAC discharge list serving as reference for comparison to the participant's self-reported medication list at 7 days following PAC discharge. Discrepancies were categorized as additions, omissions, and dose discrepancies and were organized by common medication classes and risk of harm (eg, 2015 Beers Criteria). Ordinal logistic regression assessed for patient risk factors for PAC discharge discrepancy count.

RESULTS

A total of 184 participants had 7-day PAC discharge medication data. Participants were predominately female (67%) and Caucasian (83%) with a median of 16 prehospital medications [interquartile range (IQR) 11, 20]. At the 7-day follow-up, 98% of participants had at least 1 medication discrepancy, with a median number of 7 medication discrepancies (IQR 4, 10) per person, 4 (IQR 2, 6) of which were potentially inappropriate medications as defined by the Beers Criteria. Higher medication discrepancies at index hospital admission and receipt of caregiver assistance with medications were 2 key predictors of medication discrepancies in the week after PAC discharge to home.

CONCLUSIONS AND IMPLICATIONS

Older patients transitioning home from a PAC facility are at high risk for medication discrepancies. This study underscores the need for interventions targeted at this overlooked transition period, especially as patients resume responsibility for managing their own medications after both a hospital and PAC stay.

Patient-reported predictors of postdischarge mortality after cardiac hospitalization

BACKGROUND

Adults hospitalized for cardiovascular events are at high risk for postdischarge mortality. Screening of psychosocial risk is prioritized by the Joint Commission. We tested whether key patient-reported psychosocial and behavioral measures could predict posthospitalization mortality in a cohort of adults hospitalized for a cardiovascular event.

METHODS

We conducted a prospective cohort study to test the prognostic utility of validated patient-reported measures, including health literacy, social support, health behaviors and disease management, and socioeconomic status. Cox survival analyses of mortality were conducted over a median of 3.5 years.

RESULTS

Among 2977 adults hospitalized for either acute coronary syndrome or acute decompensated heart failure, the mean age was 53 years, and 60% were male. After adjusting for demographic, clinical, and other psychosocial factors, mortality risk was greatest among patients who reported being unemployed (hazard ratio [HR]: 1.99, 95% confidence interval [CI]): 1.30-3.06), retired (HR: 2.14, 95% CI: 1.60-2.87), or unable to work due to disability (HR: 2.36, 95% CI: 1.73-3.21), as compared to those who were employed. Patient-reported perceived health competence (PHCS-2) and exercise frequency were also associated with mortality risk after adjusting for all other variables (HR: 0.86, 95% CI: 0.73-1.00 per four-point increase in PHCS-2; HR: 0.86, 95% CI: 0.77-0.96 per 3-day increase in exercise frequency, respectively).

CONCLUSIONS

Patient-reported measures of employment status, perceived health competence, and exercise frequency independently predict mortality after a cardiac hospitalization. Incorporating these brief, valid measures into hospital-based screening may help with prognostication and targeting patients for resources during post-discharge transitions of care.

Vulnerability to functional decline is associated with noncardiovascular cause of 90-day readmission in hospitalized patients with heart failure

BACKGROUND

Hospital readmission is common among patients with heart failure. Vulnerability to decline in physical function may increase the risk of noncardiovascular readmission for these patients, but the association between vulnerability and the cause of unplanned readmission is poorly understood, inhibiting the development of effective interventions.

OBJECTIVES

We examined the association of vulnerability with the cause of readmission (cardiovascular vs. noncardiovascular) among hospitalized patients with acute decompensated heart failure.

DESIGNS, SETTINGS, AND PARTICIPANTS

This prospective longitudinal study is part of the Vanderbilt Inpatient Cohort Study.

MAIN OUTCOME AND MEASURES

The primary outcome was the cause of unplanned readmission (cardiovascular vs. noncardiovascular). The primary independent variable was vulnerability, measured using the Vulnerable Elders Survey (VES-13).

RESULTS

Among 804 hospitalized patients with acute decompensated heart failure, 315 (39.2%) experienced an unplanned readmission within 90 days of discharge. In a multinomial logistic model with no readmission as the reference category, higher vulnerability was associated with readmission for noncardiovascular causes (relative risk ratio [RRR] = 1.36, 95% confidence interval [CI]: 1.06-1.75) in the first 90 days after discharge. The VES-13 score was not associated with readmission for cardiovascular causes (RRR = 0.94, 95% CI: 0.75-1.17).

CONCLUSIONS

Vulnerability to functional decline predicted noncardiovascular readmission risk among hospitalized patients with heart failure. The VES-13 is a brief, validated, and freely available tool that should be considered in planning care transitions. Additional work is needed to examine the efficacy of interventions to monitor and mitigate noncardiovascular concerns among vulnerable patients with heart failure being discharged from the hospital.

Roles of Health Literacy in Relation to Social Determinants of Health and Recommendations for Informatics-Based Interventions: Systematic Review

BACKGROUND

Health literacy (HL) is the ability to make informed decisions using health information. As health data and information availability increase due to online clinic notes and patient portals, it is important to understand how HL relates to social determinants of health (SDoH) and the place of informatics in mitigating disparities.

OBJECTIVE

This systematic literature review aims to examine the role of HL in interactions with SDoH and to identify feasible HL-based interventions that address low patient understanding of health information to improve clinic note-sharing efficacy.

METHODS

The review examined 2 databases, Scopus and PubMed, for English-language articles relating to HL and SDoH. We conducted a quantitative analysis of study characteristics and qualitative synthesis to determine the roles of HL and interventions.

RESULTS

The results (n=43) were analyzed quantitatively and qualitatively for study characteristics, the role of HL, and interventions. Most articles (n=23) noted that HL was a result of SDoH, but other articles noted that it could also be a mediator for SdoH (n=6) or a modifiable SdoH (n=14) itself.

CONCLUSIONS

The multivariable nature of HL indicates that it could form the basis for many interventions to combat low patient understandability, including 4 interventions using informatics-based solutions. HL is a crucial, multidimensional skill in supporting patient understanding of health materials. Designing interventions aimed at improving HL or addressing poor HL in patients can help increase comprehension of health information, including the information contained in clinic notes shared with patients.

Unpacking the Public Health Triad of Social Inequality in Health, Health Literacy, and Quality of Life-A Scoping Review of Research Characteristics

Social inequalities in health, health literacy, and quality of life serve as distinct public health indicators, but it remains unclear how and to what extent they are applied and combined in the literature. Thus, the characteristics of the research have yet to be established, and we aim to identify and describe the characteristics of research that intersects social inequality in health, health literacy, and quality of life. We conducted a scoping review with systematic searches in ten databases. Studies applying any design in any population were eligible if social inequality in health, health literacy, and quality of life were combined. Citations were independently screened using Covidence. The search yielded 4111 citations, with 73 eligible reports. The reviewed research was mostly quantitative and aimed at patient populations in a community setting, with a scarcity of reports specifically defining and assessing social inequality in health, health literacy, and quality of life, and with only 2/73 citations providing a definition for all three. The published research combining social inequality in health, health literacy, and quality of life is heterogeneous regarding research designs, populations, contexts, and geography, where social inequality appears as a contextualizing variable.

Patient-reported predictors of post-discharge mortality after cardiac hospitalization

Background

Adults hospitalized for cardiovascular events are at high risk for post-discharge mortality. Hospital-based screening of health-related psychosocial risk factors is now prioritized by the Joint Commission and the National Quality Forum to achieve equitable, high-quality care. We tested our hypothesis that key patient-reported psychosocial and behavioral measures could predict post-hospitalization mortality in a cohort of adults hospitalized for a cardiovascular event.

Methods

This was a prospective cohort of adults hospitalized at Vanderbilt University Medical Center. Validated patient-reported measures of health literacy, social support, disease self-management, and socioeconomic status were used as predictors of interest. Cox survival analyses of mortality were conducted over a median 3.5-year follow-up (range: 1.25 - 5.5 years).

Results

Among 2,977 adults, 1,874 (63%) were hospitalized for acute coronary syndrome and 1,103 (37%) were hospitalized for acute decompensated heart failure; 60% were male; and the mean age was 53 years. After adjusting for demographic, clinical, and other psychosocial factors, mortality risk was greatest among patients who reported being unable to work due to disability (Hazard Ratio (HR) 2.36, 95% Confidence Interval (CI): 1.73-3.21), who were retired (HR 2.14, 95% CI 1.60-2.87), and who reported unemployment (HR 1.99, 95% CI 1.30-3.06) as compared to those who were employed. Patient-reported measures of disease self-management, perceived health competence and exercise frequency, were also associated with mortality risk after full covariate adjustment (HR 0.86, 95% CI 0.73-1.00 per four-point increase), (HR 0.86, 95% CI 0.77-0.96 per three-day change), respectively.

Conclusions

Patient-reported measures of employment status independently predict post-discharge mortality after a cardiac hospitalization. Measure of disease self-management also have prognostic modest utility. Hospital-based screening of psychosocial risk is increasingly prioritized in legislative policy. Incorporating brief, valid measures of employment status and disease self-management factors may help target patients for psychosocial, financial, and rehabilitative resources during post-discharge transitions of care.

Weaknesses in the Continuity of Care of Puerperal Women: An Integrative Literature Review

The aim of the present study was to identify how the transition of care from the hospital to the community occurs from the perspective of puerperal women at risk. An integrative literature review was performed, with the question: "How does the transition of care for at-risk puerperal women from the hospital to the community occur?" The search period ranged from 2013 to 2020, in the following databases: PubMed, LILACS, SciELO, and Scopus. MESH, DeCS and Boolean operators "OR" and "AND" are used in the following crossover analysis: patient transfer OR transition care OR continuity of patient care OR patient discharge AND postpartum period, resulting in 6 articles. The findings denote discontinuity of care, given the frequency of non-adherence to the puerperal consultation. Transition studies of care in the puerperium were not found, which requires proposing new studies.

Association of Perceived Health Competence With Cardiac Rehabilitation Initiation

PURPOSE

Cardiac rehabilitation (CR), a program of supervised exercise and cardiovascular risk management, is widely underutilized. Psychological factors such as perceived health competence, or belief in one's ability to achieve health-related goals, may play a role in CR initiation. The aim of this study was to evaluate the association of perceived health competence with CR initiation among patients hospitalized for acute coronary syndrome (ACS) after adjusting for demographic, clinical, and psychosocial characteristics.

METHODS

The Vanderbilt Inpatient Cohort Study (VICS) characterized the effect of psychosocial characteristics on post-discharge outcomes in ACS inpatients hospitalized from 2011 to 2015. The primary outcome for this analysis was participation in an outpatient CR program. The primary predictor was the two-item Perceived Health Competence Scale (PHCS-2), which yields a score from 2 to 10 (higher scores indicate greater perceived health competence). Multiple logistic regression was used to evaluate the relationship between the PHCS-2 and CR initiation.

RESULTS

A total of 1809 VICS participants (median age: 61 yr, 39% female) with ACS were studied, of whom 294 (16%) initiated CR. The PHCS-2 was associated with a higher odds of CR initiation (OR = 1.15/point increase: 95% CI, 1.06-1.26, P = .001) after adjusting for covariates. Participants with comorbid heart failure had a lower odds of CR initiation (OR = 0.31: 95% CI, 0.16-0.60, P < .001) as did current smokers (OR = 0.64: 95% CI, 0.43-0.96, P = .030).

CONCLUSION

Perceived health competence is associated with outpatient CR initiation in patients hospitalized with ACS. Interventions designed to support perceived health competence may be useful for improving CR participation.

Movement is Life-Optimizing Patient Access to Total Joint Arthroplasty: Housing Security and Discharge Planning Disparities

Patients undergoing total joint arthroplasty should be screened for housing insecurity. Housing insecurity in the United States ranges from 10% to 15%, which is predisposed to those who are low-income, racial minorities, and unmarried. Osteoarthritic pain has a notable effect on function and quality of life and may prevent many individuals from continuing with their jobs. There is an inexorable, cyclic, structurally reinforced relationship between housing and health: where chronic illness affects housing security leading to issues with access to care and ultimately issues with health status. Housing insecurity is currently an imposed barrier to surgery. However, creative solutions exist to address housing insecurity, such as insurance company waivers, community resources (eg, churches) and organizations (eg, Meals on Wheels), halfway houses, and temporary housing (eg, hotels). Optimization for discharge planning in these vulnerable populations includes short-term stay in rehabilitation or skilled nursing facilities, home health services, or outpatient therapy.

Impact of Limited E-Health Literacy on the Overall Survival of Patients With Cancer

PURPOSE

Digitalization of the health care system is transforming cancer patient care. Although many studies have investigated the determinants of a limited digital health literacy, the association between frailty factors and overall survival (OS) of these patients has never been assessed.

METHODS

A retrospective noninterventional study included 15,244 adult patients with cancer diagnosed between January 1, 2015, and December 31, 2017, and treated at the Centre Léon Bérard. Limited e-health literacy was defined as the absence of an e-mail address in the electronic patient record. An Inverse Probability of Treatment-Weighted Kaplan-Meier estimate and a multivariate Cox proportional hazards model including interaction terms were used to adjust for confounding on measured covariates.

RESULTS

In total, 15,244 adults with cancer were included: 55% women, with a median age of 62 years (19-103), and 35.5% had a metastatic disease. More than half (n = 8,771, 57.5%) had entered their e-mail address in their electronic patient record, and 4,020 (26.4%) opened their own patient portal. The median follow-up was 3.6 years (range: 0-6.8). Inverse Probability of Treatment-weighted Kaplan-Meier estimates showed a significantly better OS for patients with an e-mail address (P < .001). In multivariate analysis integrating interaction terms, male gender (hazard ratio [HR] = 1.27; 95% CI, 1.15 to 1.41; P < .001), older age (HR = 1.02; 95% CI, 1.02 to 1.03; P < .001), de novo metastatic setting (HR = 2.63; 95% CI, 2.47 to 2.79; P < .001), and no e-mail address (HR = 1.63; 95% CI, 1.33 to 2.00; P < .001) were significantly associated with worse OS.

CONCLUSION

Our results support a strong association between the limited level of literacy and OS. A more in-depth study integrating variables such as socioeconomic level and location of residence would enrich these results.

Trust in Hospital Physicians Among Patients With Substance Use Disorder Referred to an Addiction Consult Service: A Mixed-methods Study

BACKGROUND

Trust is essential in patient-physician relationships. Hospitalized patients with substance use disorders (SUDs) often experience stigma and trauma in the hospital, which can impede trust. Little research has explored the role of hospital-based addictions care in creating trusting relationships with patients with SUDs. This study describes how trust in physicians changed among hospitalized people with SUDs who were seen by an interprofessional addiction medicine service.

METHODS

We analyzed data from hospitalized patients with SUD seen by an addiction consult service from 2015 to 2018. Participants completed surveys at baseline and 30 to 90 days after hospital discharge. Follow-up assessments included open-ended questions exploring participant experiences with hospitalization and the addiction consult service. We measured provider trust using the Wake Forest Trust scale. We modeled trust trajectories using discrete mixture modeling, and sampled qualitative interviews from those trust trajectories.

RESULTS

Of 328 participants with SUD who had prior hospitalizations but had not previously been seen by an addiction consult service, 196 (59.8%) had both baseline and follow-up trust scores. We identified 3 groups of patients: Persistent-Low Trust, Increasing Trust, and Persistent-High Trust and 4 qualitative themes around in-hospital trust: humanizing care, demonstrating addiction expertise, reliability, and granting agency.

CONCLUSIONS

Most participants retained or increased to high trust levels after hospitalization with an addiction consult service. Addiction consult services can create environments where healthcare providers build trust with, and humanize care for, hospitalized patients with SUD, and can also mitigate power struggles that hospitalized patients with SUD frequently experience.

Social Determinants of Health and 30-Day Readmissions Among Adults Hospitalized for Heart Failure in the REGARDS Study

BACKGROUND

It is not known which social determinants of health (SDOH) impact 30-day readmission after a heart failure (HF) hospitalization among older adults. We examined the association of 9 individual SDOH with 30-day readmission after an HF hospitalization.

METHODS AND RESULTS

Using the REGARDS study (Reasons for Geographic and Racial Differences in Stroke), we included Medicare beneficiaries who were discharged alive after an HF hospitalization between 2003 and 2014. We assessed 9 SDOH based on the Healthy People 2030 Framework: race, education, income, social isolation, social network, residential poverty, Health Professional Shortage Area, rural residence, and state public health infrastructure. The primary outcome was 30-day all-cause readmission. For each SDOH, we calculated incidence per 1000 person-years and multivariable-adjusted hazard ratios of readmission. Among 690 participants, the median age was 76 years at hospitalization (interquartile range, 71-82), 44.3% were women, 35.5% were Black, 23.5% had low educational attainment, 63.0% had low income, 21.0% had zip code-level poverty, 43.5% resided in Health Professional Shortage Areas, 39.3% lived in states with poor public health infrastructure, 13.1% were socially isolated, 13.3% had poor social networks, and 10.2% lived in rural areas. The 30-day readmission rate was 22.4%. In an unadjusted analysis, only Health Professional Shortage Area was significantly associated with 30-day readmission; in a fully adjusted analysis, none of the 9 SDOH were individually associated with 30-day readmission.

CONCLUSIONS

In this modestly sized national cohort, although prevalent, none of the SDOH were associated with 30-day readmission after an HF hospitalization. Policies or interventions that only target individual SDOH to reduce readmissions after HF hospitalizations may not be sufficient to prevent readmission among older adults.

Variability in skilled nursing facility screening and admission processes: Implications for value-based purchasing

BACKGROUND

Hospitalized older adults are increasingly admitted to skilled nursing facilities (SNFs) for posthospital care. However, little is known about how SNFs screen and evaluate potential new admissions. In an era of increasing emphasis on postacute care outcomes, these processes may represent an important target for interventions to improve the value of SNF care.

PURPOSE

The aim of this study was to understand (a) how SNF clinicians evaluate hospitalized older adults and make decisions to admit patients to an SNF and (b) the limitations and benefits of current practices in the context of value-based payment reforms.

METHODS

We used semistructured interviews to understand the perspective of 18 clinicians at three unique SNFs-including physicians, nurses, therapists, and liaisons. All transcripts were analyzed using a general inductive theme-based approach.

RESULTS

We found that the screening and admission processes varied by SNF and that variability was influenced by three key external pressures: (a) inconsistent and inadequate transfer of medical documentation, (b) lack of understanding among hospital staff of SNF processes and capabilities, and (c) hospital payment models that encouraged hospitals to discharge patients rapidly. Responses to these pressures varied across SNFs. For example, screening and evaluation processes to respond to these pressures included gaining access to electronic medical records, providing inpatient physician consultations prior to SNF acceptance, and turning away more complex patients for those perceived to be more straightforward rehabilitation patients.

CONCLUSIONS

We found facility behavior was driven by internal and external factors with implications for equitable access to care in the era of value-based purchasing.

PRACTICE IMPLICATIONS

SNFs can most effectively respond to these pressures by increasing their agency within hospital-SNF relationships and prioritizing more careful patient screening to match patient needs and facility capabilities.

The Role of Social Determinates of Health in Discharge Practices

Major risks associated with inadequate discharge preparation and execution include medication errors, adverse drug events, and hospital readmissions. Nurses must develop pertinent skills to assess how the social environment impacts patients' likelihood of a safe and healthy transition back into the community as they prepare patients for discharge. Recognition and consideration of social determinants of health are critical to minimizing health disparities, enhancing health equity and supporting positive patient outcomes. Examples of strategies for enhanced discharge practices include implicit bias assessment and training, screening for food insecurity, and assessment for quality referral sources.

Health Literacy and Outcomes Among Patients With Heart Failure: A Systematic Review and Meta-Analysis

OBJECTIVES

The purpose of this study was to determine if health literacy is associated with mortality, hospitalizations, or emergency department (ED) visits among patients living with heart failure (HF).

BACKGROUND

Growing evidence suggests an association between health literacy and health-related outcomes in patients with HF.

METHODS

We searched Embase, MEDLINE, PsycINFO, and EBSCO CINAHL from inception through January 1, 2019, with the help of a medical librarian. Eligible studies evaluated health literacy among patients with HF and assessed mortality, hospitalizations, and ED visits for all causes with no exclusion by time, geography, or language. Two reviewers independently selected studies, extracted data, and assessed the methodological quality of the identified studies.

RESULTS

We included 15 studies, 11 with an overall high methodological quality. Among the observational studies, an average of 24% of patients had inadequate or marginal health literacy. Inadequate health literacy was associated with higher unadjusted risk for mortality (risk ratio [RR]: 1.67; 95% confidence interval [CI]: 1.18 to 2.36), hospitalizations (RR: 1.19; 95% CI: 1.09 to 1.29), and ED visits (RR: 1.17; 95% CI: 1.03 to 1.32). When the adjusted measurements were combined, inadequate health literacy remained statistically associated with mortality (RR: 1.41; 95% CI: 1.06 to 1.88) and hospitalizations (RR: 1.12; 95% CI: 1.01 to 1.25). Among the 4 interventional studies, 2 effectively improved outcomes among patients with inadequate health literacy.

CONCLUSIONS

In this study, the estimated prevalence of inadequate health literacy was high, and inadequate health literacy was associated with increased risk of death and hospitalizations. These findings have important clinical and public health implications and warrant measurement of health literacy and deployment of interventions to improve outcomes.

Should We Implement Geographic or Patient-Reported Social Determinants of Health Measures In Cardiovascular Patients

Objectives

To compare patient-reported social determinants of health (SDOH) to the Brokamp Area Deprivation Index (ADI), and evaluate the association of patient-reported SDOH and ADI with mortality in patients with cardiovascular disease (CVD).

Design

Prospective cohort.

Setting

Academic medical center.

Participants

Adults with acute coronary syndrome (ACS) and/or acute exacerbation of heart failure (HF) hospitalized between 2011 and 2015.

Methods

Patient-reported SDOH included: income range, education, health insurance, and household size. ADI was calculated using census tract level variables of poverty, median income, high school completion, lack of health insurance, assisted income, and vacant housing.

Primary Outcome

All-cause mortality, up to 5 years follow-up.

Results

The sample was 60% male, 84% White, and 93% insured; mean patient-reported household income was $48,000 (SD $34,000). ADI components were significantly associated with corresponding patient-reported variables. In age, sex, and race adjusted Cox regression models, ADI was associated with mortality for ACS (HR 1.23, 95% CI 1.06, 1.42), but not HF (HR 1.09, 95% CI .99, 1.21). Mortality models for ACS improved with consideration of social determinants data (C-statistics: base demographic model=.612; ADI added=.644; patient-reported SDOH added=.675; both ADI and patient-reported SDOH added=.689). HF mortality models improved only slightly (C-statistics: .600, .602, .617, .620, respectively).

Conclusions

The Brokamp ADI is associated with mortality in hospitalized patients with CVD. In the absence of available patient-reported data, hospitals could implement the Brokamp ADI as an approximation for patient-reported data to enhance risk stratification of patients with CVD.

Disparities in Research Participation by Level of Health Literacy

OBJECTIVE

To determine at which phase in the recruitment process for participation in clinical research studies do health literacy and other patient characteristics influence recruitment outcomes.

PATIENTS AND METHODS

Using a sample of 5872 patients hospitalized with cardiovascular disease approached for participation in the Vanderbilt Inpatient Cohort Study from October 2011 through December 2015, we examined the independent association of patients' health literacy with two steps in their research participation decision-making process: (1) research interest - willingness to hear more about a research study; and (2) research participation - the decision to enroll after an informed consent discussion. Best practices for effective health communication were implemented in recruitment approaches and informed consent processes. Using logistic regression models, we determined patient characteristics independently associated with patients' willingness to hear about and participate in the study.

RESULTS

In unadjusted analyses, participants with higher health literacy, and those who were younger, female, or had more education had higher levels of both research interest and research participation. Health literacy remained independently associated with both outcomes in multivariable models, after adjustment for sociodemographic factors.

CONCLUSION

Because identical variables predicted both research interest and eventual consent, efforts to recruit broad populations must include acceptable methods of approaching potential participants as well as explaining study materials.

Práticas de enfermeiros de um hospital universitário na continuidade do cuidado para a atenção primária

Resumo Objetivo compreender as práticas dos enfermeiros de um hospital universitário na continuidade do cuidado para a atenção primária. Método estudo exploratório, descritivo e qualitativo, realizado entre agosto e novembro de 2019, em hospital universitário no Sul do Brasil, com 21 enfermeiros e a diretora de Enfermagem, aplicando-se, respectivamente, um instrumento on-line na plataforma Survey Monkey e uma entrevista semiestruturada. Os dados coletados foram submetidos à Análise de Conteúdo segundo Minayo. Resultados emergiram três categorias: práticas dos enfermeiros; fortalezas e fragilidades e competências para a continuidade do cuidado. Na admissão e alta, os enfermeiros realizam entrevista e exame físico do paciente. Os pontos positivos foram a comunicação e o conhecimento do contexto familiar da equipe multiprofissional hospitalar e os negativos, a falta de sistema informatizado, a integração dos profissionais do hospital com a atenção primária, o enfermeiro gestor de altas e o protocolo de contrarreferência. A continuidade do cuidado requer, dos enfermeiros, experiência profissional, conhecimento sobre a rede de atenção, habilidades de comunicação, liderança e tomada de decisão. Conclusão e implicações para a prática os enfermeiros compreendem a importância da continuidade do cuidado, entretanto, algumas fragilidades encontradas na instituição dificultam a realização dessas práticas.

Health literacy and quality of life in hospitalized heart failure patients: a cross-sectional study

INTRODUCTION

Heart Failure (HF) treatment may be improved by good knowledge of the disease (Health Literacy) that, despite the well-established role on improving self-care, preventing complications and avoiding worse outcomes, has little evidence on affecting QoL of HF patients. Therefore, the objective of the present study was to evaluate the impact of Health Literacy on QoL in hospitalized HF patients.

METHODOLOGY

A cross-sectional exploratory study was conducted with HF patients hospitalized at a public cardiological hospital. Health Literacy was assessed using the "Questionnaire about Heart Failure Patients' Knowledge of Disease" and QoL using the "Minnesota Living with Heart Failure Questionnaire" (MLHFQ). The association between Health Literacy and QoL was assessed by linear regression (P<0.05).

RESULTS

50 patients were included in the study; the mean Health Literacy score was 34.2 ± 15.1 (the majority presenting acceptable or better knowledge). The mean MLHFQ score was 73.5 ± 19.8. The one-year hospital readmission rate (β=+3.8; P=0.009) and the patients' Health Literacy score (β=-0.4; P=0.024) or good knowledge category (β=-20.2; P=0.016) were independently associated with QoL.

CONCLUSION

While the readmission rate was inversely associated with QoL, the better the HF knowledge the better QoL in hospitalized HF patients.

Social Determinants of Health and 90-Day Mortality After Hospitalization for Heart Failure in the REGARDS Study

Background

Outcomes following heart failure (HF) hospitalizations are poor, with 90‐day mortality rates of 15% to 20%. Although prior studies found associations between individual social determinants of health (SDOH) and post‐discharge mortality, less is known about how an individuals’ total burden of SDOH affects 90‐day mortality.

Methods and Results

We included participants of the REGARDS (Reasons for Geographic and Racial Differences in Stroke) Study who were Medicare beneficiaries aged ≥65 years discharged alive after an adjudicated HF hospitalization. Guided by the Healthy People 2020 Framework, we examined 9 SDOH. First, we examined age‐adjusted associations between each SDOH and 90‐day mortality; those associated with 90‐day mortality were used to create an SDOH count. Next, we determined the hazard of 90‐day mortality by the SDOH count, adjusting for confounders. Over 10 years, 690 participants were hospitalized for HF at 440 unique hospitals in the United States; there were a total of 79 deaths within 90 days. Overall, 28% of participants had 0 SDOH, 39% had 1, and 32% had ≥2. Compared with those with 0, the age‐adjusted hazard ratio for 90‐day mortality among those with 1 SDOH was 2.89 (95% CI, 1.46–5.72) and was 3.06 (1.51–6.19) among those with ≥2 SDOH. The adjusted hazard ratio was 2.78 (1.37–5.62) and 2.57 (1.19–5.54) for participants with 1 SDOH and ≥2, respectively.

Conclusions

While having any of the SDOH studied here markedly increased risk of 90‐day mortality after an HF hospitalization, a greater burden of SDOH was not associated with significantly greater risk in our population.

Opioid Prescriptions at Hospital Discharge Are Associated With More Postdischarge Healthcare Utilization

Background

Many patients use opioids for nonmalignant pain, and opioid use in the general population has been associated with poor long‐term outcomes. The use of high‐risk medications, including opioid analgesics, may increase the risk of unplanned healthcare utilization.

Methods and Results

We performed a nested evaluation in the VICS (Vanderbilt Inpatient Cohort Study) (N=3000) on patients with an admitting diagnosis of acute coronary syndrome and/or acute decompensated heart failure. Patient enrollment occurred from October 2011 until December 2015 and involved a single investigational site, Vanderbilt University Medical Center (Nashville, TN). Of the 2495 eligible patients, 501 (20%) were discharged with an opioid prescription and were predominantly white and men, with a median age of 59 (interquartile range, 53–67) years. Our primary outcome was unplanned healthcare utilization, which included emergency department presentation or readmission. Secondary outcomes included mortality and a composite of planned utilization behaviors: cardiac rehabilitation and provider follow‐up within 30 days. Cox proportional hazards models did not show a statistically significant association with increased unplanned utilization (adjusted hazard ratio, 1.06; 95% CI, 0.87–1.28) or mortality (adjusted hazard ratio, 1.08; 95% CI, 0.84–1.39), compared with those without opioids at discharge. Patients discharged with opioids were less likely to complete planned healthcare utilization (adjusted odds ratio, 0.69; 95% CI, 0.52–0.91).

Conclusions

There are decreased odds of planned healthcare utilization among patients with acute coronary syndrome and acute decompensated heart failure discharged with opioid medication. It is imperative to understand how opioid use can affect a patient's relationship with the healthcare system.

Rethinking rehabilitation after percutaneous coronary intervention: a protocol of a multicentre cohort study on continuity of care, health literacy, adherence and costs at all care levels (the CONCARDPCI)

INTRODUCTION

Percutaneous coronary intervention (PCI) aims to provide instant relief of symptoms, and improve functional capacity and prognosis in patients with coronary artery disease. Although patients may experience a quick recovery, continuity of care from hospital to home can be challenging. Within a short time span, patients must adjust their lifestyle, incorporate medications and acquire new support. Thus, CONCARD^PCI will identify bottlenecks in the patient journey from a patient perspective to lay the groundwork for integrated, coherent pathways with innovative modes of healthcare delivery. The main objective of the CONCARD^PCI is to investigate (1) continuity of care, (2) health literacy and self-management, (3) adherence to treatment, and (4) healthcare utilisation and costs, and to determine associations with future short and long-term health outcomes in patients after PCI.

METHODS AND ANALYSIS

This prospective multicentre cohort study organised in four thematic projects plans to include 3000 patients. All patients undergoing PCI at seven large PCI centres based in two Nordic countries are prospectively screened for eligibility and included in a cohort with a 1-year follow-up period including data collection of patient-reported outcomes (PRO) and a further 10-year follow-up for adverse events. In addition to PROs, data are collected from patient medical records and national compulsory registries.

ETHICS AND DISSEMINATION

Approval has been granted by the Norwegian Regional Committee for Ethics in Medical Research in Western Norway (REK 2015/57), and the Data Protection Agency in the Zealand region (REG-145-2017). Findings will be disseminated widely through peer-reviewed publications and to patients through patient organisations.

Active Life: a project for a safe hospital-community transition after arthroplasty

ABSTRACT Objective: To define the criteria for the continuity of care to elderly people submitted to arthroplasty. Method: This is a qualitative study, inserted in the constructivist paradigm, whose methodological option fell on research-action. The participants were the health professionals of an orthopedic service and of the community care teams in the area of the hospital. Results: The different techniques allowed us to identify the difficulties in the safe transition from the hospital to the community. At this level, two categories of criteria for continuity of care emerged: criteria associated with the risk of ineffective management of the therapeutic regimen, and criteria associated with the knowledge and level of competence of the informal caregiver. Final Considerations: An elderly person undergoing arthroplasty (hip or knee) has functional alterations that affect their capacity for self-care and may lead to dependence, our findings allowed the design of an algorithm to facilitate clinical decision making and promote a safe hospital-community transition.

Changes in vulnerability among older patients with cardiovascular disease in the first 90 days after hospital discharge: A secondary analysis of a cohort study

OBJECTIVES

(1) To compare changes in vulnerability after hospital discharge among older patients with cardiovascular disease who were discharged home with self-care versus a home healthcare (HHC) referral and (2) to examine factors associated with changes in vulnerability in this period.

DESIGN

Secondary analysis of longitudinal data from a cohort study.

PARTICIPANTS AND SETTING

834 older (≥65 years) patients hospitalised for acute coronary syndromes and/or acute decompensated heart failure who were discharged home with self-care (n=713) or an HHC referral (n=121).

OUTCOME

Vulnerability was measured using Vulnerable Elders Survey 13 (VES-13) at baseline (prior to hospital admission) and 30 days and/or 90 days after hospital discharge. Effects of HHC referral on postdischarge change in vulnerability were examined using three linear regression approaches, with potential confounding on HHC referral adjusted by propensity score matching.

RESULTS

Overall, 44.4% of the participants were vulnerable at prehospitalisation baseline and 34.4% were vulnerable at 90 days after hospital discharge. Compared with self-care patients, HHC-referred patients were more vulnerable at baseline (66.9% vs 40.3%), had more increase (worsening) in VES-13 score change (B=-1.34(-2.07, -0.61), p<0.001) in the initial 30 days and more decrease (improvement) in VES-13 score change (B=0.83(0.20, 1.45), p=0.01) from 30 to 90 days after hospital discharge. Baseline vulnerability and the HHC referral attributed to 14%-16% of the variance in vulnerability change during the 90 postdischarge days, and 6% was attributed by patient age, race (African-American), depressive symptoms, and outpatient visits and hospitalisations in the past year.

CONCLUSION

After adjusting for preceding vulnerability and covariates, older hospitalised patients with cardiovascular disease referred to HHC had delayed recovery in vulnerability in first initial 30 days after hospital discharge and greater improvement in vulnerability from 30 to 90 days after hospital discharge. HHC seemed to facilitate improvement in vulnerability among older patients with cardiovascular disease from 30 to 90 days after hospital discharge.

Preparation of the discharge of relatives of children using antibiotics: contributions of nursing

Abstract Objective: To describe the discharge preparation for relatives of hospitalized children for continuing antibiotic therapy at home, from the nurse perspective. Method: A descriptive and qualitative research, performed in the ward of a pediatric hospital in Rio de Janeiro. It was attended by fifteen nurses through semi-structured interviews, between April and May 2018, and data was submitted to Thematic Analysis. Results: The following thematic units emerged: Preparing the relatives for the discharge as a punctual moment; Professionals involved in the preparation of the discharge for relatives; Educational strategies in preparing the relatives for the discharge; and Communication among professionals in preparing the relatives for the discharge. Conclusion and implications for practice: There is a need to systematize the discharge process of the child that leaves the hospital to finish their therapeutic scheme with antibiotics at home, thereby avoiding inappropriate use and therapeutic errors.

Health Literacy and 1-Year Mortality: Mechanisms of Association in Adults Hospitalized for Cardiovascular Disease

OBJECTIVE

To test theorized patient-level mediators in the causal pathway between health literacy (HL) and 1-year mortality in adults with cardiovascular disease (CVD).

PATIENTS AND METHODS

A total of 3000 adults treated at Vanderbilt University Hospital from October 11, 2011, through December 18, 2015, for acute coronary syndrome or acute decompensated heart failure (ADHF) participated in the Vanderbilt Inpatient Cohort Study. Participants completed a bedside-administered survey and consented to health record review and longitudinal follow-up. Multivariable mediation models examined the direct and indirect effects of HL (a latent variable with 4 indicators) with 1-year mortality after discharge (dichotomous). Hypothesized mediators included social support, health competence, health behavior, comorbidity index, type of CVD diagnosis, and previous-year hospitalizations.

RESULTS

Of the 2977 patients discharged from the hospital (60% male; mean age, 61 years; 83% non-Hispanic white, 37% admitted for ADHF), 17% to 23% had inadequate HL depending on the measure, and 10% (n=304) died within 1 year. The total effect of lower HL on 1-year mortality (adjusted odds ratio [AOR]=1.31; 95% CI, 1.01-1.69) was decomposed into an indirect effect (AOR=1.50; 95% CI, 1.35-1.67) via the mediators and a nonsignificant direct effect (AOR=0.87; 95% CI, 0.66-1.14). Each SD decrease in HL was associated with an absolute 3.2 percentage point increase in the probability of 1-year mortality via mediators admitted for ADHF, comorbidities, health behavior, health competence, and previous-year hospitalizations (listed by contribution to indirect effect).

CONCLUSION

Patient-level factors link low HL and mortality. Health competence and health behavior are modifiable mediators that could be targeted by interventions post hospitalization for CVD.

Something Old, Something New: When Gender Matters in the Relationship between Social Support and Health

This paper investigates how social support differentially benefits self-rated health among men and women hospitalized with heart disease. Using cross-sectional data about patients admitted to a university hospital, we examine the extent to which gender moderates effects for the frequency of contact with family, friends, and neighbors on health and whether these effects differ between those with new versus established diagnoses. We find that gender differentiates the effect of nonmarital family contact on health but only when heart disease is newly diagnosed. When newly diagnosed, more frequent contact with family is associated with better self-rated health for women but not men. Men and women with preexisting diagnoses benefit equally from more frequent contact with family.

Numeracy, Health Literacy, Cognition, and 30-Day Readmissions among Patients with Heart Failure

BACKGROUND

Numeracy, health literacy, and cognition are important for chronic disease management. Prior studies have found them to be associated with poorer selfcare and worse clinical outcomes, but limited data exists in the context of heart failure (HF), a condition that requires patients to monitor their weight, fluid intake, and dietary salt, especially in the posthospitalization period.

OBJECTIVE

To examine the relationship between numeracy, health literacy, and cognition with 30-day readmissions among patients hospitalized for acute decompensated HF (ADHF).

DESIGN, SETTING, PATIENTS

The Vanderbilt Inpatient Cohort Study is a prospective longitudinal study of adults hospitalized with acute coronary syndromes and/or ADHF. We studied 883 adults hospitalized with ADHF.

MEASUREMENTS

During their hospitalization, a baseline interview was performed in which demographic characteristics, numeracy, health literacy, and cognition were assessed. Through chart review, clinical characteristics were determined. The outcome of interest was 30-day readmission to any acute care hospital. To examine the association between numeracy, health literacy, cognition, and 30-day readmissions, multivariable Poisson (log-linear) regression was used.

RESULTS

Of the 883 patients admitted for ADHF, 23.8% (n = 210) were readmitted within 30 days; 33.9% of the study population had inadequate numeracy skills, 24.6% had inadequate/marginal literacy skills, and 53% had any cognitive impairment. Numeracy and cognition were not associated with 30-day readmissions. Though (objective) health literacy was associated with 30-day readmissions in unadjusted analyses, it was not in adjusted analyses.

CONCLUSIONS

Numeracy, health literacy, and cognition were not associated with 30-day readmission among this sample of patients hospitalized with ADHF.

Financial strain is associated with medication nonadherence and worse self-rated health among cardiovascular patients

Non-traditional indicators of socioeconomic status (SES; e.g., home ownership) may be just as or even more predictive of health outcomes as traditional indicators of SES (e.g., income). This study tested whether financial strain (i.e., difficulty paying monthly bills) predicted medication non-adherence and worse self-rated health. Research assistants administered surveys to 1,527 patients with acute coronary syndromes or acute decom-pensated heart failure. In adjusted models, having a higher income was associated with being more adherent (p &lt; .001), but was non-significant when adjusted for financial strain. Education, income, less financial strain, and being employed were each associated with better self-rated health (p &lt; .001). Financial strain was associated with less adherence (β =-.17, p &lt; .001) and worse self-rated health (β = -.23, p &lt; .001), and mediated the effect of income on adherence (coeff = .078 [BCa 95% CI: .051 to .108]). Future research should further explore the nuanced link between SES and health behaviors and outcomes.

Investigating the effect of sociodemographic factors on 30-day hospital readmission among medical patients in Toronto, Canada: a prospective cohort study

OBJECTIVE

To examine the influence of patient-level sociodemographic factors on the incidence of hospital readmission within 30 days among medical patients in a large Canadian metropolitan city.

DESIGN

Prospective cohort study.

SETTING AND PARTICIPANTS

Patients admitted to the General Internal Medicine service of an urban teaching hospital in Toronto, Canada participated in a survey of sociodemographic information. Patients were not surveyed if deemed medically unstable, receiving care in medical/surgical step-down beds or were isolated for infection control. Included in the final analysis was a diverse cohort of 1427 adult, non-palliative, patients who were discharged home.

MEASURES

Thirteen patient-level sociodemographic variables were examined in relation to time to unplanned all-cause readmission within 30 days. Illness level was accounted for by the following covariates: self-perceived health status, previous hospital utilisation, primary diagnosis case mix group, Charlson Comorbidity Index score and inpatient length of stay.

RESULTS

Approximately, 14.4% (n=205) of patients experienced readmission within 30 days. Sociodemographic factors were not significantly associated with time to readmission in unadjusted and adjusted analyses. Indicators of illness level, namely, previous hospitalisations, were the strongest risk factors for readmission within this cohort. One previous admission (adjusted HR 1.78; 95% CI 1.22 to 2.59, P<0.01) and at least four previous emergency department visits (adjusted HR 2.33; 95% CI 1.46 to 4.43, P<0.01) were associated with increased hazard of readmission within 30 days.

CONCLUSIONS

Patient-level sociodemographic factors did not influence the incidence of unplanned all-cause readmission within 30 days. Further research is needed to understand the generalisability of our findings and investigate whether contextual factors, such as access to universal health insurance coverage, attenuate the effects of sociodemographic factors.

Know thy eHealth user: Development of biopsychosocial personas from a study of older adults with heart failure

BACKGROUND

Personas are a canonical user-centered design method increasingly used in health informatics research. Personas-empirically-derived user archetypes-can be used by eHealth designers to gain a robust understanding of their target end users such as patients.

OBJECTIVE

To develop biopsychosocial personas of older patients with heart failure using quantitative analysis of survey data.

METHOD

Data were collected using standardized surveys and medical record abstraction from 32 older adults with heart failure recently hospitalized for acute heart failure exacerbation. Hierarchical cluster analysis was performed on a final dataset of n=30. Nonparametric analyses were used to identify differences between clusters on 30 clustering variables and seven outcome variables.

RESULTS

Six clusters were produced, ranging in size from two to eight patients per cluster. Clusters differed significantly on these biopsychosocial domains and subdomains: demographics (age, sex); medical status (comorbid diabetes); functional status (exhaustion, household work ability, hygiene care ability, physical ability); psychological status (depression, health literacy, numeracy); technology (Internet availability); healthcare system (visit by home healthcare, trust in providers); social context (informal caregiver support, cohabitation, marital status); and economic context (employment status). Tabular and narrative persona descriptions provide an easy reference guide for informatics designers.

DISCUSSION

Personas development using approaches such as clustering of structured survey data is an important tool for health informatics professionals. We describe insights from our study of patients with heart failure, then recommend a generic ten-step personas development process. Methods strengths and limitations of the study and of personas development generally are discussed.

Clusters of Healthy and Unhealthy Eating Behaviors Are Associated With Body Mass Index Among Adults

OBJECTIVE

To identify eating styles from 6 eating behaviors and test their association with body mass index (BMI) among adults.

DESIGN

Cross-sectional analysis of self-report survey data.

SETTING

Twelve primary care and specialty clinics in 5 states.

PARTICIPANTS

Of 11,776 adult patients who consented to participate, 9,977 completed survey questions.

VARIABLES MEASURED

Frequency of eating healthy food, frequency of eating unhealthy food, breakfast frequency, frequency of snacking, overall diet quality, and problem eating behaviors. The primary dependent variable was BMI, calculated from self-reported height and weight data.

ANALYSIS

k-Means cluster analysis of eating behaviors was used to determine eating styles. A categorical variable representing each eating style cluster was entered in a multivariate linear regression predicting BMI, controlling for covariates.

RESULTS

Four eating styles were identified and defined by healthy vs unhealthy diet patterns and engagement in problem eating behaviors. Each group had significantly higher average BMI than the healthy eating style: healthy with problem eating behaviors (β = 1.9; P < .001), unhealthy (β = 2.5; P < .001), and unhealthy with problem eating behaviors (β = 5.1; P < .001).

CONCLUSIONS AND IMPLICATIONS

Future attempts to improve eating styles should address not only the consumption of healthy foods but also snacking behaviors and the emotional component of eating.

Health Literacy and Heart Failure: A Systematic Review

BACKGROUND

Low health literacy affects millions of Americans, putting those who are affected at a disadvantage and at risk for poorer health outcomes. Low health literacy can act as a barrier to effective disease self-management; this is especially true for chronic diseases such as heart failure (HF) that require complicated self-care regimens.

PURPOSE

This systematic review examined quantitative research literature published between 1999 and 2014 to explore the role of health literacy among HF patients. The specific aims of the systematic review are to (1) describe the prevalence of low health literacy among HF patients, (2) explore the predictors of low health literacy among HF patients, and (3) discuss the relationship between health literacy and HF self-care and common HF outcomes.

METHODS

A systematic search of the following databases was conducted, PubMed, CINAHL Plus, Embase, PsycINFO, and Scopus, using relevant keywords and clear inclusion and exclusion criteria.

CONCLUSIONS

An average of 39% of HF patients have low health literacy. Age, race/ethnicity, years of education, and cognitive function are predictors of health literacy. In addition, adequate health literacy is consistently correlated with higher HF knowledge and higher salt knowledge.

CLINICAL IMPLICATIONS

Considering the prevalence of low health literacy among in the HF population, nurses and healthcare professionals need to recognize the consequences of low health literacy and adopt strategies that could minimize its detrimental effect on the patient's health outcomes.

Human factors analysis, design, and evaluation of Engage, a consumer health IT application for geriatric heart failure self-care

Human factors and ergonomics (HFE) and related approaches can be used to enhance research and development of consumer-facing health IT systems, including technologies supporting the needs of people with chronic disease. We describe a multiphase HFE study of health IT supporting self-care of chronic heart failure by older adults. The study was based on HFE frameworks of "patient work" and incorporated the three broad phases of user-centered design: study or analysis; design; and evaluation. In the study phase, data from observations, interviews, surveys, and other methods were analyzed to identify gaps in and requirements for supporting heart failure self-care. The design phase applied findings from the study phase throughout an iterative process, culminating in the design of the Engage application, a product intended for continuous use over 30 days to stimulate self-care engagement, behavior, and knowledge. During the evaluation phase, we identified a variety of usability issues through expert heuristic evaluation and laboratory-based usability testing. We discuss the implications of our findings regarding heart failure self-care in older adults and the methodological challenges of rapid translational field research and development in this domain.

Perceived health competence predicts health behavior and health-related quality of life in patients with cardiovascular disease

OBJECTIVE

Evaluate the effect of perceived health competence, a patient's belief in his or her ability to achieve health-related goals, on health behavior and health-related quality of life.

METHODS

We analyzed 2063 patients hospitalized with acute coronary syndrome and/or congestive heart failure at a large academic hospital in the United States. Multivariable linear regression models investigated associations between the two-item perceived health competence scale (PHCS-2) and positive health behaviors such as medication adherence and exercise (Health Behavior Index) as well as health-related quality of life (5-item Patient Reported Outcome Information Measurement System Global Health Scale).

RESULTS

After multivariable adjustment, perceived health competence was highly associated with health behaviors (p<0.001) and health-related quality of life (p<0.001). Low perceived health competence was associated with a decrease in health-related quality of life between hospitalization and 90days after discharge (p<0.001).

CONCLUSIONS

Perceived health competence predicts health behavior and health-related quality of life in patients hospitalized with cardiovascular disease as well as change in health-related quality of life after discharge.

PRACTICE IMPLICATIONS

Patients with low perceived health competence may be at risk for a decline in health-related quality of life after hospitalization and thus a potential target for counseling and other behavioral interventions.

What Patient Characteristics Influence Nurses' Assessment of Health Literacy?

Overestimation of patients' health literacy skills is common among nurses and physicians. At Vanderbilt University Hospital, nurses routinely ask patients the 3 Brief Health Literacy Screen (BHLS) questions. Data from 2 studies that recruited patients at Vanderbilt University Hospital-the Health Literacy Screening (HEALS) study and the Vanderbilt Inpatient Cohort Study (VICS)-were analyzed to compare the BHLS score recorded by nurses during clinical care with the score recorded by trained research assistants during the same hospitalization. Logistic regression models determined which patient characteristics were associated with nurses documenting higher health literacy scores than research assistants. Overall, the majority (60%) of health literacy scores were accurate, though nurses recorded meaningfully higher health literacy scores in 28.4% of HEALS patients and 35.6% of VICS patients. In the HEALS cohort, patients who were male and had less education were more likely to have higher health literacy scores recorded by nurses (odds ratio [OR] = 1.93, 95% confidence interval [CI] [1.24, 3.00]; and OR = 0.80, 95% CI [0.74, 0.88], respectively). In the VICS cohort, patients who were older, were male, and had less education were more likely to have higher health literacy scores recorded by nurses (OR = 1.01, 95% CI [1.003, 1.02]; OR = 1.49, 95% CI [1.20, 1.84]; and OR = 0.87, 95% CI [0.83, 0.90], respectively). These findings suggest that health literacy scores recorded by nurses for male patients and patients with less education could be overestimated. Thus, health care professionals should be aware of this tendency and should verify the results of routine health literacy screening tests, especially in certain patient groups.

Preparedness for hospital discharge and prediction of readmission

BACKGROUND, OBJECTIVE

Patients' self-reported preparedness for discharge has been shown to predict readmission. It is unclear what differences exist in the predictive abilities of 2 available discharge preparedness measures. To address this gap, we conducted a comparison of these measures.

DESIGN, SETTING, PATIENTS

Adults hospitalized for cardiovascular diagnoses were enrolled in a prospective cohort.

MEASUREMENTS

Two patient-reported preparedness measures assessed during postdischarge calls: the 11-item Brief Prescriptions, Ready to re-enter community, Education, Placement, Assurance of safety, Realistic expectations, Empowerment, Directed to appropriate services (B-PREPARED) and the 3-item Care Transitions Measure (CTM-3). Cox proportional hazard models analyzed the relationship between preparedness and time to first readmission or death at 30 and 90 days, adjusted for readmission risk using the administrative database-derived Length of stay, Acuity, Comorbidity, and Emergency department use (LACE) index and other covariates.

RESULTS

Median preparedness scores were: B-PREPARED 21 (interquartile range [IQR] 18-22) and CTM-3 77.8 (IQR 66.7-100). In individual Cox models, a 4-point increase in B-PREPARED score was associated with a 16% decrease in time to readmission or death at 30 and 90 days. A 10-point increase in CTM-3 score was not associated with readmission or death at 30 days, but was associated with a 6% decrease in readmission or death at 90 days. In models with both preparedness scores, B-PREPARED retained an association with readmission or death at both 30 and 90 days. However, neither preparedness score was as strong a predictor as the LACE index when all were included in the model predicting 30- and 90-day readmission or death.

CONCLUSION

The B-PREPARED score was more strongly associated with readmission or death than the more widely adopted CTM-3, but neither predicted readmission as well as the LACE index. Journal of Hospital Medicine 2016;11:603-609. © 2016 Society of Hospital Medicine.

Health literacy is independently associated with self-care behavior in patients with heart failure

OBJECTIVE

Health literacy (HL) has been recognized as an important concept in patient education and disease management for heart failure (HF). However, previous studies on HL have focused predominantly on the relationships between functional HL (the ability to read and write), comprehensive HL including the ability to access information (communicative HL), and the ability to critically evaluate information (critical HL). Self-care behavior has not been evaluated. This study determined the relationship between functional, communicative, and critical HL and self-care behavior in HF patients.

METHODS

Cross-sectional analysis of the data was completed for HL, HF-related knowledge, and HF-related self-care behaviors. Sociodemographic and clinical characteristics were also assessed. Multivariate linear regression analysis was used to estimate the associations between literacy and self-care behavior.

RESULTS

249 patients with HF were assessed (mean age, 67.7±13.9years). Patients with low HL had poorer knowledge and self-care behavior than those with high HL. Critical HL was an independent determinant of self-care behavior (sβ=-0.154, P=0.027).

CONCLUSIONS

Critical HL was independently associated with self-care behavior in HF patients.

PRACTICE IMPLICATIONS

Effective intervention should be developed to improve patient skills for critically analyzing information and making decisions.

Psychometric Evaluation of a Korean Version of the Adherence to Refills and Medications Scale (ARMS) in Adults With Type 2 Diabetes

PURPOSE

The purpose of the study was to examine the reliability and validity of the Adherence to Refills and Medications Scale-Korean (ARMS-K) among Korean adults with type 2 diabetes.

METHODS

The Korean translated ARMS-K was back-translated to ensure translation equivalency. A cross-sectional survey was used to evaluate the psychometric properties with exploratory factor analysis for validity and Cronbach's alpha coefficients for reliability.

RESULTS

The factor analysis of construct validity identified 3 dimensions of the ARMS-K, explaining 54.7% of the total variance. The internal consistency reliability for the total instrument was acceptable with a Cronbach's alpha of .801. There was good correlation between the ARMS-K and 8-item Morisky Medication Adherence Scale-Korean version (r = -0.698), indicating that these scales measure theoretically related constructs as evidence of convergent validity. As evidence of known groups validity, there was a significant association between the ARMS-K score and glycemic control (P = .048), indicating that the good glycemic controlled group was more likely to have a higher rate of adherence to refills and medications than the poor glycemic controlled group.

CONCLUSIONS

These results support the cross-cultural applicability of the concepts underlying the ARMS-K. The ARMS-K can be used not only to assess adherence to refills and medications in Koreans with diabetes but also to examine the potential role of adherence to refills and medications in enhanced glycemic control of people with diabetes in a variety of clinical settings.

Effects of stress, health competence, and social support on depressive symptoms after cardiac hospitalization

Little is known about the role of stress on the psychological well-being of patients after cardiac hospitalization or about factors that protect against or exacerbate the effects of stress. We use prospective data from 1542 patients to investigate the relationship between post-discharge stress and changes in depressive symptoms, and whether the level of prior depressive symptoms, health competence, and perceived social support moderate this relationship. Net of depressive symptoms in the 2 weeks prior to hospitalization, higher levels of post-discharge stress significantly increase depressive symptoms 30 days after discharge. The level of prior depressive symptoms moderates the effect of stress. On the other hand, perceived health competence and social support buffer the negative effects of post-discharge stress. Knowing which patients are particularly vulnerable to experiencing stress and a subsequent increase in depressive symptoms can help trigger interventions prior to discharge and possibly ameliorate the prevalence of depression.

Development of a multivariable model to predict vulnerability in older American patients hospitalised with cardiovascular disease

OBJECTIVES

To identify vulnerable cardiovascular patients in the hospital using a self-reported function-based screening tool.

PARTICIPANTS

Prospective observational cohort study of 445 individuals aged ≥ 65 years admitted to a university medical centre hospital within the USA with acute coronary syndrome and/or decompensated heart failure.

METHODS

Participants completed an inperson interview during hospitalisation, which included vulnerable functional status using the Vulnerable Elders Survey (VES-13), sociodemographic, healthcare utilisation practices and clinical patient-specific measures. A multivariable proportional odds logistic regression model examined associations between VES-13 and prior healthcare utilisation, as well as other coincident medical and psychosocial risk factors for poor outcomes in cardiovascular disease.

RESULTS

Vulnerability was highly prevalent (54%) and associated with a higher number of clinic visits, emergency room visits and hospitalisations (all p<0.001). A multivariable analysis demonstrating a 1-point increase in VES-13 (vulnerability) was independently associated with being female (OR 1.55, p=0.030), diagnosis of heart failure (OR 3.11, p<0.001), prior hospitalisations (OR 1.30, p<0.001), low social support (OR 1.42, p=0.007) and depression (p<0.001). A lower VES-13 score (lower vulnerability) was associated with increased health literacy (OR 0.70, p=0.002).

CONCLUSIONS

Vulnerability to functional decline is highly prevalent in hospitalised older cardiovascular patients and was associated with patient risk factors for adverse outcomes and an increased use of healthcare services.

Potentials of internet-based patient engagement and education programs to reduce hospital readmissions: a spotlight on need in heart failure

Internet-based applications and mobile health technology has advanced at unprecedented rates over the last decade and has proved to be a highly effective platform for communication. Simultaneously, the United States health care system has reached a critical and unsustainable level of spending, arising largely from ingrained system inefficiencies and overall suboptimum communication. Internet-based and mobile health technology offers an innovative solution to both of these problems. The prevention of readmissions for heart failure provides an excellent example of how this new technology can be used in today's health care environment to improve patient care.

Validation of a Short, 3-Item Version of the Subjective Numeracy Scale

BACKGROUND AND OBJECTIVE

Efficiency in scale design reduces respondent burden. A brief but reliable measure of numeracy may provide a useful research tool eligible for integration into large epidemiological studies or clinical trials. Our goal was to validate a 3-item version of the Subjective Numeracy Scale (SNS-3).

DESIGN AND SETTING

We examined 7 separate cross-sectional data sets: patients in the emergency department (n = 208), clinic (n = 205), and hospital (n = 460; n = 2053) and patients with chronic kidney disease (n = 147), with diabetes (n = 318), and on hemodialysis (n = 143).

MEASUREMENTS

Internal reliability of the SNS-3 was assessed with Cronbach's α. Criterion validity was determined by nonparametric correlations of the SNS-3 with SNS-8 and other measures of numeracy; construct validity was determined by correlations with measures of health literacy and education.

RESULTS

The SNS-3 had good internal reliability (median Cronbach's α = 0.78) and correlated highly with the full SNS (median ρ = 0.91). The SNS-3 was significantly correlated with other measures of numeracy (e.g., median ρ = 0.57 with the Wide Range Achievement Test 4), health literacy (e.g., median ρ = 0.35 with the Shortened Test of Functional Health Literacy in Adults), and education (median ρ = 0.41), providing good evidence of criterion and construct validity.

CONCLUSION

The SNS-3 is sufficiently reliable and valid to be used as a measure of subjective numeracy.

Effect of Health Literacy on Research Follow-Up

Previous research has not examined the effect of health literacy on research subjects' completion of scheduled research follow-up. This article evaluates patient factors associated with incomplete research follow-up at three time points after enrollment in a large, hospital-based prospective cohort study. Predictor variables included health literacy, age, race, gender, education, employment status, difficulty paying bills, hospital diagnosis, length of stay, self-reported global health status, depression, perceived health competence, medication adherence, and health care system distrust. In a sample of 2,042 patients, multivariable models demonstrated that lower health literacy and younger age were significantly associated with a lower likelihood of completing research follow-up interviews at 2-3 days, 30 days, and 90 days after hospital discharge. In addition, patients who had less education, were currently employed, and had moderate financial stress were less likely to complete 90-day follow-up. This study is the first to demonstrate that lower health literacy is a significant predictor of incomplete research follow-up.

Medication Nonadherence Before Hospitalization for Acute Cardiac Events

Medication nonadherence increases the risk of hospitalization and poor outcomes, particularly among patients with cardiovascular disease. The purpose of this study was to examine characteristics associated with medication nonadherence among adults hospitalized for cardiovascular disease. Patients in the Vanderbilt Inpatient Cohort Study who were admitted for acute coronary syndrome or heart failure completed validated assessments of self-reported medication adherence (the Adherence to Refills and Medications Scale), demographic characteristics, health literacy, numeracy, social support, depressive symptoms, and health competence. We modeled the independent predictors of nonadherence before hospitalization, standardizing estimated effects by each predictor's interquartile range. Among 1,967 patients studied, 70.7% indicated at least some degree of medication nonadherence leading up to their hospitalization. Adherence was significantly lower among patients with lower health literacy (0.18-point change in adherence score per interquartile range change in health literacy), lower numeracy (0.28), lower health competence (0.30), and more depressive symptoms (0.52) and those of younger age, of non-White race, of male gender, or with less social support. Medication nonadherence in the period before hospitalization is more prevalent among patients with lower health literacy, numeracy, or other intervenable psychosocial factors. Addressing these factors in a coordinated care model may reduce hospitalization rates.

Design and rationale of the comprehensive evaluation of risk factors in older patients with AMI (SILVER-AMI) study

Background

While older adults (age 75 and over) represent a large and growing proportion of patients with acute myocardial infarction (AMI), they have traditionally been under-represented in cardiovascular studies. Although chronological age confers an increased risk for adverse outcomes, our current understanding of the heterogeneity of this risk is limited. The Comprehensive Evaluation of Risk Factors in Older Patients with AMI (SILVER-AMI) study was designed to address this gap in knowledge by evaluating risk factors (including geriatric impairments, such as muscle weakness and cognitive impairments) for hospital readmission, mortality, and health status decline among older adults hospitalized for AMI.

Methods/Design

SILVER-AMI is a prospective cohort study that is enrolling 3000 older adults hospitalized for AMI from a recruitment network of approximately 70 community and academic hospitals across the United States. Participants undergo a comprehensive in-hospital assessment that includes clinical characteristics, geriatric impairments, and health status measures. Detailed medical record abstraction complements the assessment with diagnostic study results, in-hospital procedures, and medications. Participants are subsequently followed for six months to determine hospital readmission, mortality, and health status decline. Multivariable regression will be used to develop risk models for these three outcomes.

Discussion

SILVER-AMI will fill critical gaps in our understanding of AMI in older patients. By incorporating geriatric impairments into our understanding of post-AMI outcomes, we aim to create a more personalized assessment of risk and identify potential targets for interventions.
