Health literacy and health outcomes in hypertension: An integrative review.
Ontology highlight
ABSTRACT: Objective
The aim of this study was to summarize the evidence of health literacy and health outcomes in hypertensive patients.Methods
Articles published in English were searched from six databases: MEDLINE, CINAHL, Embase, ERIC, psycINFO, and SCOPUS. The articles published up to September 2017 were included.Results
Nineteen publications were included in the review. There was quality and consistent evidence that hypertensive patients with lower literacy had poorer knowledge. There was inconsistent evidence to show the relationship between health literacy and clinical outcomes, of systolic and diastolic blood pressure, and blood pressure control; behavioral outcomes, of self-care, self-efficacy, adherence; patient-physician interactions outcomes, of patient-physician communication, patient trust, involvement in decision making and other outcomes.Conclusion
The person with low health literacy is likely to have poor knowledge of hypertension. However, there is insufficient evidence to suggest that health literacy is associated with outcomes of hypertension independently.

Project description:BackgroundOlder adults, identified as 65 years and over, a population for which low health literacy is prevalent, represented most people attending primary health care services provided by the Health Service Executive (HSE) in Ireland in 2019. Any limitation in a person's health literacy, specifically their ability to access, understand and use health information, can affect their ability to make healthcare related decisions. Information on the evidence for health literacy interventions is also required by healthcare providers and policy makers to inform decision-making and service development to improve outcomes for older people. This review aimed to synthesise the evidence on health literacy interventions and health literacy-related outcomes for older adults. The specific objectives were to (1) identify what health literacy interventions exist in relation to older adults' ability to access, understand, and use health information, (2) determine the health literacy-related outcomes of these interventions, and (3) identify any trends or patterns which may exist between intervention type and outcome.MethodsThis review was conducted by following PRISMA guidelines. The electronic databases PubMed, Embase and Scopus were searched for relevant studies concerning health literacy interventions for older persons. Study data were subsequently analysed using a narrative thematic approach in the context of the three key health literacy characteristics; the ability to access, understand and use health information.ResultsThirty-four studies were identified that met the inclusion criteria. The findings show a potential link between individual-focussed health literacy interventions and positive health literacy-related outcomes in relation to older persons' ability to understand and use health information. The review also found that use of health literacy level assessment tools varied with studies either using different tools for the same older adult cohort, or failing to assess pre-intervention health literacy levels altogether.ConclusionsThe potential trend found between individual-focused interventions and positive health literacy outcomes suggests that implementing health literacy-related interventions directly to the individual is key. Furthermore, our study found an inconsistency amongst the included studies in relation to the implementation of health literacy assessment tools, with different tools used across most studies, and some studies choosing not to utilise any assessment tool.

Project description:BackgroundLow health literacy is considered a potential barrier to improving health outcomes in people with diabetes and other chronic conditions, although the evidence has not been previously systematically reviewed.ObjectiveTo identify, appraise, and synthesize research evidence on the relationships between health literacy (functional, interactive, and critical) or numeracy and health outcomes (i.e., knowledge, behavioral and clinical) in people with diabetes.MethodsEnglish-language articles that addressed the relationship between health literacy or numeracy and at least one health outcome in people with diabetes were identified by two reviewers through searching six scientific databases, and hand-searching journals and reference lists.FindingsSeven hundred twenty-three citations were identified and screened, 196 were considered, and 34 publications reporting data from 24 studies met the inclusion criteria and were included in this review. Consistent and sufficient evidence showed a positive association between health literacy and diabetes knowledge (eight studies). There was a lack of consistent evidence on the relationship between health literacy or numeracy and clinical outcomes, e.g., A1C (13 studies), self-reported complications (two studies), and achievement of clinical goals (one study); behavioral outcomes, e.g., self-monitoring of blood glucose (one study), self-efficacy (five studies); or patient-provider interactions (i.e., patient-physician communication, information exchange, decision-making, and trust), and other outcomes. The majority of the studies were from US primary care setting (87.5 %), and there were no randomized or other trials to improve health literacy.ConclusionsLow health literacy is consistently associated with poorer diabetes knowledge. However, there is little sufficient or consistent evidence suggesting that it is independently associated with processes or outcomes of diabetes-related care. Based on these findings, it may be premature to routinely screen for low health literacy as a means for improving diabetes-related health-related outcomes.

Project description:BackgroundOptimal management of chronic diseases, such as type 2 diabetes and hypertension, often include prescription medications. Medication adherence (MA) is one component of self-management. Optimization through digital health-eHealth and mHealth-could enhance patient awareness and/or communication between the patient and provider.ObjectiveMedication adherence is a major issue that affects 50%-60% of chronically ill adults. Digital health refers to eHealth and mHealth, collectively, and as these technologies become more accessible, remote health delivery is increasingly available as an adjunct to improve medication adherence; communicate with patients and providers; and provide education to patients, families, and communities. The objective of this integrative review was to examine the types of digital health technologies that targeted medication adherence in the adult population with diabetes or hypertension.MethodsAn integrative review was conducted using databases within EBSCOhost, PubMed, and Scopus. Eligible studies available as of September 2016 had to be written in English, had to contain digital health interventions to improve medication adherence to prescription medications in adults 18 years or older, and had to focus on diabetes or hypertension.ResultsOf the 337 located studies, 13 (3.9%) used a digital health intervention for medication adherence to prescribed medications for diabetes or hypertension and were assessed according to the Chronic Care Model.ConclusionsThe 13 studies included in this review found no conclusive evidence of improved medication adherence using digital health interventions such as interactive voice response (IVR), short message service (SMS) text messaging, telemonitoring, and interactive software technology. Among the 13 studies were digital health interventions that foster medication adherence via one-way communication to the patient or two-way communication between the patient and health care provider for adjunct medication adherence strategies. More research is needed to determine which digital health interventions are most beneficial for individuals with diabetes or hypertension.

Project description:BackgroundDigital health literacy has emerged as a critical skill set to navigate the digital age.ObjectiveThis review sought to broadly summarize the literature on associations between digital health literacy and (1) sociodemographic characteristics, (2) health resource use, and (3) health outcomes in the general population, patient groups, or parent or caregiver groups.MethodsA rapid review of literature published between January 2016 and May 2022 was conducted through a search of 4 web-based databases. Articles were included on the basis of the following keywords: "measured digital health literacy," "digital literacy," "ehealth literacy," "e-health literacy," "electronic health literacy," or "internet health literacy" in adult populations; participants were from countries where English was the primary language; studies had to be cross-sectional, longitudinal, prospective, or retrospective, and published in English.ResultsThirty-six articles met the inclusion criteria. Evidence on the associations between digital health literacy and sociodemographic characteristics varied (27/36, 75% included studies), with higher education (16/21, 76.2% studies that examined the association) and younger age (12/21, 57.1% studies) tending to predict higher digital health literacy; however, other studies found no associations. No differences between genders were found across the majority of studies. Evidence across ethnic groups was too limited to draw conclusions; some studies showed that those from racial and ethnic minority groups had higher digital health literacy than White individuals, while other studies showed no associations. Higher digital health literacy was associated with digital health resource use in the majority of studies (20/36, 55.6%) that examined this relationship. In addition, higher digital health literacy was also associated with health outcomes across 3 areas (psychosocial outcomes; chronic disease and health management behaviors; and physical outcomes) across 17 included studies (17/36, 47.2%) that explored these relationships. However, not all studies on the relationship among digital health literacy and health resource use and health outcomes were in the expected direction.ConclusionsThe review presents mixed results regarding the relationship between digital health literacy and sociodemographic characteristics, although studies broadly found that increased digital health literacy was positively associated with improved health outcomes and behaviors. Further investigations of digital health literacy on chronic disease outcomes are needed, particularly across diverse groups. Empowering individuals with the skills to critically access and appraise reliable health information on digital platforms and devices is critical, given emerging evidence that suggests that those with low digital health literacy seek health information from unreliable sources. Identifying cost-effective strategies to rapidly assess and enhance digital health literacy capacities across community settings thus warrants continued investigation.

Project description:OBJECTIVE: To impute limited health literacy from commonly measured socio-demographic data and to compare it to the Short-Test of Functional Health Literacy in Adults (S-TOFHLA) for estimating the influence of limited health literacy on health status in the elderly. METHODS: The Prudential Medicare Study assesses the S-TOFHLA score, leading to a "reference standard" classification of 25% of people with inadequate literacy; the National Health Interview Survey has no such assessment. We estimated a regression of S-TOFHLA on sex, age, years of schooling, and race/ethnicity in The Prudential Medicare Study data to derive a Demographic Assessment for Health Literacy (DAHL) score, and imputed inadequate literacy to the 25% with the lowest DAHL scores. Using regression, we then examined associations between several health status measures (including hypertension, diabetes, physical and mental SF-12) and inadequate literacy (imputed or test-based). RESULTS: Estimates of association using imputed inadequate literacy closely approximate those obtained using S-TOFHLA-based inadequate literacy for most outcomes examined. CONCLUSIONS: As few population surveys measure health literacy, the DAHL, a readily calculated health literacy proxy score, may be useful for expanding the scope of health literacy research in national survey data.

Project description:Low health literacy (HL) is associated with poor healthcare outcomes; mechanisms for these associations remain unclear.To elucidate how HL influences patients' interest in participating in healthcare, medical visit communication, and patient reported visit outcomes.Cross-sectional study of enrollment data from a randomized controlled trial of interventions to improve patient adherence to hypertension treatments. Participants were 41 primary care physicians and 275 of their patients. Prior to the enrollment visit, physicians received a minimal intervention or communication skills training and patients received a minimal intervention or a pre-visit coaching session. This resulted in four intervention groups (minimal patient/minimal physician; minimal patient/intensive physician; intensive patient/minimal physician; and intensive patient/intensive physician).Rapid Estimate of Adult Literacy in Medicine; patients' desire for involvement in decision making; communication behaviors; patient ratings of participatory decision making (PDM), trust, and satisfaction.A lower percentage of patients with low versus adequate literacy had controlled blood pressure. Both groups were similarly interested in participating in medical decision making. Communication behaviors did not differ based on HL except for medical question asking by patients, which was lower among low literacy patients. This was particularly true in the intensive patient /intensive physician group (3.85 vs. 6.42 questions; p = 0.002). Overall, ratings of care didn't differ based on HL; however, in analyses stratified by intervention assignment, patients with low literacy in minimal physician intervention groups reported significantly lower PDM scores than adequate literacy patients.Patients with low and adequate literacy were similarly interested in participating in medical decision making. However, low literacy patients were less likely to experience PDM in their visits. Low literacy patients in the intensive physician intervention groups asked fewer medical questions. Patients with low literacy may be less able to respond to physicians' use of patient-centered communication approaches than adequate literacy patients.

Project description:BACKGROUND:Improving the training of physicians about communication skills and patient health literacy (HL) is a major priority that remains an open question. We aimed to examine the effectiveness of communication skills training for physicians on the hypertension outcomes and the health literacy skills, self-efficacy and medication adherence in patients with uncontrolled blood pressure (BP). METHODS:A randomized, controlled trial method was conducted on 240 hypertensive patients and 35 physicians presenting to healthcare clinics in the Mashhad, Iran, from 2013 to 2014. Using stratified blocking with block sizes of 4 and 6, eligible patients with uncontrolled blood pressure were randomly allocated to the intervention and control groups. Physicians in the intervention group received educational training over 3 sessions of Focus -Group Discussion and 2 workshops. The control group received the routine care. The primary outcome was a reduction in systolic and diastolic BP from baseline to 6 months. The secondary outcome was promoting HL skills in hypertensive patients. Data were analyzed using the regression model and bivariate tests. RESULTS:After the physician communication training, there was a significant improvement in physicians-patient communication skills, hypertension outcomes, medication adherence, and self-efficacy among the patients being managed by the physicians receiving training, compared to the control group. CONCLUSION:The educational intervention leads to better BP control; it may have been sufficient training of physicians change to impact counseling, HL and self-efficacy and adherence. The quality of physician-patient communication is an important modifiable element of medical communication that may influences health outcomes in hypertensive Iranian patients.

Project description:ObjectivesThe 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).BackgroundGrowing evidence suggests an association between health literacy and health-related outcomes in patients with HF.MethodsWe 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.ResultsWe 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.ConclusionsIn 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.

Project description:Organizational health literacy (OHL)-interventions can reduce inequality and demands in health care encountered by patients. However, an overview of their impact and critical factors for organization-wide implementation is lacking. The aim of this scoping review is to summarize the evidence on: (1) the outcomes of OHL-interventions at patient, professional and organizational levels; and (2) the factors and strategies that affect implementation and outcomes of OHL-interventions. We reviewed empirical studies following the five-stage framework of Arksey and O'Malley. The databases Scopus, PubMed, PsychInfo and CINAHL were searched from 1 January 2010 to 31 December 2019, focusing on OHL-interventions using terms related to "health literacy", "health care organization" and "intervention characteristics". After a full-text review, we selected 24 descriptive stu-dies. Of these, 23 studies reported health literacy problems in relation to OHL-assessment tools. Nine out of thirteen studies reported that the use of interventions resulted in positive changes on OHL-domains regarding comprehensible communication, professionals' competencies and practices, and strategic organizational changes. Organization-wide OHL-interventions resulted in some improvement of patient outcomes but evidence was scarce. Critical factors for organization-wide implementation of OHL-interventions were leadership support, top-down and bottom-up approaches, a change champion, and staff commitment. Organization-wide interventions lead to more positive change on OHL-domains, but evidence regarding OHL-outcomes needs strengthening.

Project description:IntroductionLow health literacy is widely reported in people with chronic kidney disease (CKD) and has been associated with reduced disease self-management, poor health outcomes, increased mortality and poorer quality of life. However, these associations are still not well understood.MethodsElectronic-based systematic searches were performed to identify studies examining associations between health literacy and self-management behaviours and/or health outcomes in patients with CKD. A tabular and narrative synthesis of the data was performed. Meta-analysis was not appropriate due to the heterogeneity of study designs and methods.ResultsSearches identified 48 studies that met the inclusion criteria. A total of 41 published articles, six conference abstracts, and one thesis were included. Of the 48 studies, 11 were cohort and 37 were cross-sectional. In total there were 25,671 patients; 16,952 from cohort studies. Median study sample size was 159 (IQR 92-275). Study quality was high (5), moderate (24) and poor (19). Thirteen measures of health literacy were used. Despite the limitations of the available evidence, there appear to be consistent relationships between higher health literacy and favourable self-management behaviours for patients with CKD. Definitive relationships between health literacy and patient outcomes are far less clear and remain incompletely understood.DiscussionConclusive evidence describing a causal link between health literacy and patient outcomes remains limited, but for many outcomes, a consistent association is described. In addition to associations with mortality, hospitalisation and clinical events, there were consistent associations between health literacy and favourable self-management behaviours which could support the development of patient education aimed at improving health literacy.
