Empirical relationships between health literacy and treatment decision making: a scoping review of the literature

Communication of benefits and harms in shared decision making with patients with limited health literacy: A systematic review of risk communication strategies

OBJECTIVES

Risk communication (RC), as part of shared decision making, is challenging with people with limited health literacy (LHL). We aim to provide an overview of strategies to communicate benefits and harms of diagnostic and treatment options to this group.

METHODS

We systematically searched PubMed, Embase, Cinahl and PsycInfo. We included 28 studies on RC in informed/shared decision making without restriction to a health setting or condition and using a broad conceptualization of health literacy. Two researchers independently selected studies and one researcher performed data extraction. We descriptively compared findings for people with LHL towards recommendations for RC.

RESULTS

Health literacy levels varied in the included studies. Most studies used experimental designs, primarily on visual RC. Findings show verbal RC alone should be avoided. Framing of risk information influences risk perception (less risky when positively framed, riskier when negatively framed). Most studies recommended the use of icon arrays. Graph literacy should be considered when using visual RC.

CONCLUSIONS

The limited available evidence suggests that recommended RC strategies seem mainly to be valid for people with LHL, but more research is required.

PRACTICE IMPLICATIONS

More qualitative research involving people with LHL is needed to gain further in-depth insights into optimal RC strategies.

"A bit of everything": Health literacy interventions in chronic conditions - a systematic review

OBJECTIVE

To systematically evaluate health literacy (HL) interventions in chronic conditions by exploring theoretical perspectives, intervention content and effectiveness.

METHOD

We searched MEDLINE, Cochrane, CINAHL, EMBASE, ERIC, Web of Science and PsycINFO. Standardised systematic review methods were used, and sequences informing our research question were extracted and analysed. The study includes a descriptive summary of the included papers.

RESULTS

We included 39 unique interventions, with diabetes and heart disease as the most targeted chronic conditions. Fifty-four percent of papers included a definition of HL, but the studies showed significant heterogeneity of theoretical underpinnings, modes, measures and content. We identified 23 HL measures, mostly assessing functional HL. The HL interventions were often more complex than the measures indicated. A significant change in HL was found in 28 studies. Study quality was generally poor.

CONCLUSIONS

Interventions optimizing HL appear important to improve health outcomes in chronic conditions. To ensure cumulative knowledge development of this field we need theory-based interventions, consistency in methods and more tailored and comprehensive measures to capture the interventions' complexity.

PRACTICE IMPLICATIONS

A more valid understanding of HL interventions and measurements is needed to reach an agreed understanding of their components and intentions.

The relationships of health literacy, preferred involvement, and patient activation with perceived involvement in care among Mongolian patients with breast and cervical cancer

OBJECTIVE

To explore the relationships of health literacy, preferred involvement, and patient activation with perceived involvement in care among patients with breast and cervical cancer.

METHODS

A cross-sectional survey was conducted with patients aged 20 years or older, aware of their cancer diagnosis, and currently receiving care at the National Cancer Center, Mongolia. Descriptive statistics and multivariate regression analysis were used to identify the relationships among study variables.

RESULTS

Two hundred twenty-five patients were included in the final analysis. Patients' perceived involvement was examined as two subdomains: patient information seeking (PIS) and patient decision-making (PDM). Patient health literacy was found to only significantly influence PIS, and patient preferred involvement demonstrated a significant influence only on PDM. However, patient activation predictor was found to significantly influence both PIS and PDM (PIS [β = 0.22, p = 0.00] and PDM [β = 0.14, p = 0.00]).

CONCLUSION

Health literacy, preferred involvement, and patient activation each demonstrated distinct influences on patients' perceived involvement subdomains, with patient activation being the most important predictor.

PRACTICE IMPLICATIONS

Comprehensive strategies at the healthcare organization, professional, and patient levels may help to facilitate and advance patient involvement in care, and ultimately improve the quality of healthcare services respective to domain of patient-centeredness.

Patient and carer experience of nutrition care throughout and beyond treatment for head and neck cancer: a qualitative longitudinal study

Nutrition care plays a critical role in optimising outcomes for patients receiving treatment for head and neck cancer (HNC), with carers playing an important role in supporting patients to maintain nutrition intake. This study explores patient and carer experience of nutrition care from diagnosis of HNC to 1 year post treatment completion to identify areas for improvement of service delivery. A longitudinal qualitative study design was used with a heterogeneous sample of 20 patients and 15 carers of patients undergoing curative intent treatment for HNC. Interviews conducted at four time points provided a total of 117 interview datasets that were analysed using reflexive thematic analysis based on Gadamerian hermeneutic inquiry. Patient and carer experiences were reflected in two primary themes: (1) the battle to maintain control and (2) navigating the road ahead. This research identifies the need to co-design strategies to improve nutrition care that is inclusive of patients and carers.

Treatment selection and medication adherence for stable angina: The role of area-based health literacy

RATIONALE, AIMS, AND OBJECTIVES

Clinical studies show equivalent health outcomes from interventional procedures and treatment with medication only for stable angina patients. However, patients may be subject to overuse or access barriers for interventional procedures and may exhibit suboptimal adherence to medications. Our objective is to evaluate whether community-level health literacy is associated with treatment selection and medication adherence patterns.

METHOD

The sample included Medicare fee-for-service beneficiaries (20% random sample) with stable angina in 2007-2013. We used an area-level health literacy variable because of the lack of an individual measure in claims. We measured the association between (a) area-based health literacy with treatment selection (medication only, percutaneous coronary intervention [PCI], or coronary artery bypass grafting (CABG) surgery) and (b) area-based health literacy with medication adherence. We controlled for other factors including demographics, co-morbidity burden, dual eligibility, and area deprivation index.

RESULTS

We identified 8300 patients of whom 8.7% lived in a low health literacy area. Overall, 56% of patients received medication only, 28% received PCI, and 15% received CABG. Patients in low health literacy areas were less likely to receive CABG (-3.5 percentage points; 95% CI, -6.8 to -0.3) than were patients in high health literacy areas, but the significance was sensitive to specification. Overall, 81.5% and 71.5% of patients were adherent to antianginals and statins, respectively. Living in low health literacy areas was associated with lower adherence to antianginals (-3.3 percentage points; 95% CI, -6.1 to -0.6) but not statins.

CONCLUSIONS

Low area-based health literacy was associated with being less likely to receive CABG and lower adherence, but the differences between low and high health literacy areas were small and sensitive to model specification. Individual factors such as dual eligibility status and race/ethnicity had stronger associations with outcomes than had area-based health literacy, suggesting that this area-based measure was inadequate to account for social determinants in this study.

Factors predicting collaborative willingness of surrogates making medical decisions on the Physician Order for Scope of Treatment (POST)

Objective: The Physician's Order for Scope of Treatment (POST) indicates patient preferences regarding cardiopulmonary resuscitation (CPR), levels of care, and fluids/nutrition provision decisions. When patients become incapacitated, 'surrogates' often collaborate with physicians on POST decisions. Surrogates may vary in their willingness to collaborate, which can be problematic when physicians expect shared decision-making. No research has yet investigated collaborative decision-making among surrogates on the POST. This study investigated how six psychological variables predicted participants' desires for collaboration when completing an online decision-making task.Methods: Participants served as hypothetical surrogates and made decisions for another person on the three sections of the West Virginia POST. One-hundred-and-seventy-two adults were recruited from Amazon Mechanical Turk.Results: The six variables contributed significantly to the prediction of collaborative willingness, F (6, 163) = 5.29, p < .001, R²= 0.19. Two variables uniquely contributed: confidence and consideration of future consequences. The model most strongly predicted collaborative willingness for the CPR decision.Conclusion: This study provides a novel examination of under-researched areas: surrogate collaborative willingness and the POST. Differing risks associated with the three POST decisions may influence how surrogates value collaboration. Ways to enhance collaborative willingness when making POST decisions are discussed.

Patient and carer experience of nutrition care throughout treatment for head and neck cancer: a systematic qualitative review and thematic synthesis

Nutrition care plays a critical role in the provision of best practice care to head and neck cancer (HNC) patients, with carers playing an important role in supporting patients to maintain nutrition intake. This qualitative systematic review investigated patient and carer experience of nutrition care throughout and beyond HNC treatment. Five databases were systematically searched for qualitative studies reporting on patient and carer experience of nutrition care throughout HNC. Twenty-five studies including 435 patients and 46 carers were identified, revealing three themes: information and support in the healthcare setting, enteral feeding challenges and management, and life outside hospital. Findings highlight the importance of providing individualised person-centred nutrition care to patients with HNC and their carers. Further qualitative research is needed to inform healthcare professionals about the needs of patients and carers to provide appropriate support throughout the treatment trajectory across and between different treatment modalities.

Implementation of a health-literate patient decision aid for chest pain in the emergency department

OBJECTIVE

The aim of this study was to investigate the implementation of a new health-literacy-tested patient decision aid for chest pain in Emergency Department (ED) patients. Outcomes included disposition, knowledge, decisional conflict and satisfaction prior to discharge. Patient health literacy was explored as a factor that may explain disparities in sub-group analysis of all outcomes.

METHODS

A health-literacy adapted tool was deployed using a pre/post intervention design. Patients enrolled during the intervention period were given the adapted chest pain decision aid that was used in conversation with their emergency medicine physician to decide on their course of action prior to being discharged.

RESULTS

A total of 169 participants were surveyed and used in the final analysis. Patients in the usual care group were 2.6 times more likely to be admitted for chest pain than patients in the intervention group. Knowledge scores were higher in the intervention group, while no significant differences were observed in decisional conflict and patient satisfaction, or by patient health literacy level.

CONCLUSION AND PRACTICE IMPLICATIONS

Using the adapted chest pain decision tool in emergency medicine may improve knowledge and reduce admissions, while addressing known barriers to understanding related to patient health literacy.

Health numeracy skills of medical students:cross-sectional and controlled before-and-after study

BACKGROUND

Although numeracy, defined as understanding and handling numbers, is an important skill for the medical profession, it is not clear whether it changes during graduate medical education and whether it can be improved by specific interventions. The objective of this study was to assess objective and subjective numeracy levels at different stages of medical education and explore whether a research methodology/statistics course improves numeracy levels in a longer period.

METHODS

We performed cross-sectional and controlled before-and-after studies. First-year sociology students and first- to sixth-year medical students from the in the cross sectional study and two groups of first-year medical students in a controlled before-and-after study. The intervention was a course on biostatistics and research methodology using blended approach. Numeracy was measured using Subjective Numeracy Scale (Cronbach α = 0.70) and Numeracy Understanding in Medicine instrument (Cronbach α = 0.75).

RESULTS

Whereas first-year medical students did not differ from first-year sociology students in objective numeracy, medicine students had higher results on subjective numeracy. Students from higher years of medical school had generally higher subjective and objective numeracy scores. In the controlled before-and-after study, the intervention group improved more in subjective numeracy (median difference on a 0-8 scale = 0.5, 95% CI 0.3 to 0.7 vs - 0.4, 95% CI - 0.4 to - 0.1, P < 0.001) but not in objective numeracy.

CONCLUSIONS

Although the numeracy levels at the beginning of the medical school are within the range of non-medical population, both objective and subjective numeracy improve during the higher years of medical school. Curriculum during medical school may help in numeracy increase, while research methodology training may help to increase subjective but not objective numeracy skills.

Association of Preferences for Papillary Thyroid Cancer Treatment With Disease Terminology: A Discrete Choice Experiment

Importance

Given recent evidence of overdiagnosis and overtreatment of small papillary thyroid cancers (PTCs) and other low-risk cancers, strategies are needed to help patients consider less invasive treatment options.

Objectives

To determine which factors influence treatment preferences for patients with PTC, and the trade-offs in treatment factors people are willing to accept, and to understand how terminology influences preferences and benefit-harm trade-offs.

Design, Setting, and Participants

Preferences in PTC treatment were evaluated using a discrete choice experiment (DCE) conducted as a web-based survey using an existing public online research panel. Participants were randomized to receive 1 of 2 frames of information based on the terminology used to describe the condition: "cancer" or "lesion." Participants chose between 3 treatment options for PTC (thyroidectomy, hemithyroidectomy, and active surveillance). Analyses were conducted using a mixed logit model.

Main Outcomes and Measures

The main outcome variable was treatment preference; attributes of treatment options and sociodemographic characteristics were explanatory variables.

Results

The DCE was completed by 2054 participants (993 [48.3%] men and 1061 [51.7%] women; mean [SD] age, 46.0 [16.5] years) with no history of thyroid cancer. Participants preferred options with less frequent follow-up, lower out-of-pocket costs, lower chances of having voice and calcium level problems, and a lower risk of developing invasive thyroid cancer and of dying of thyroid cancer. When trading benefits against harms, participants were willing to accept a higher number of extra patients experiencing adverse effects to avoid a thyroid cancer death when the condition was described as a cancer compared with a lesion. Specifically, participants for whom the condition was described as a cancer were willing to accept more patients requiring lifelong medication (mean, 273; 95% CI, 207-339 vs mean, 98; 95% CI, 66-131), experiencing calcium problems (mean, 110; 95% CI, 77-144 vs mean, 56; 95% CI, 55-58), and fatigue (mean, 958; 95% CI, 691-1224 vs mean, 469; 95% CI, 375-564). For both the cancer and lesion terminology, health literacy consistently was associated with preferences for treatment options. Those with lower health literacy had a significantly lower preference for less invasive treatment options.

Conclusions and Relevance

This study makes an important contribution to understanding how attributes of treatment options, terminology, and patient characteristics, in particular health literacy, influence treatment decision making for PTC. As a result of increasing evidence of the indolent nature of PTC and other low-risk cancers, strategies to deal with potential overtreatment are critically needed.

The role of non-medical factors in physicians' decision-making process in a pediatric telemedicine service

The complex process of medical decision-making is prone also to medically extraneous influences or "non-medical" factors. We aimed to investigate the possible role of non-medical factors in doctors' decision-making process in a telemedicine setting. Interviews with 15 physicians who work in a pediatric telemedicine service were conducted. Those included a qualitative section, in which the physicians were asked about the role of non-medical factors in their decisions. Their responses to three clinical scenarios were also analyzed. In an additional quantitative section, a random sample of 339 parent -physician consultations, held during 2014-2017, was analyzed retrospectively. Various non-medical factors were identified with respect to their possible effect on primary and secondary decisions, the accuracy of diagnosis, and "reasonability" of the decisions. Various non-medical factors were found to influence physicians' decisions. Those factors were related to the child, the applying parent, the physician, the interaction between the doctor and parents, the shift, and to demographic considerations, and were also found to influence the ability to make an accurate diagnosis and "reasonable" decisions. Our conclusion was that non-medical factors have an impact on doctor's decisions, even in the setting of telemedicine, and should be considered for improving medical decisions in this milieu.

Patient-Clinician Decision Making for Stable Angina: The Role of Health Literacy

BACKGROUND

Stable angina patients have difficulty understanding the tradeoffs between treatment alternatives. In this analysis, we assessed treatment planning conversations for stable angina to determine whether inadequate health literacy acts as a barrier to communication that may partially explain this difficulty.

METHODS

We conducted a descriptive analysis of patient questionnaire data from the PCI Choice Trial. The main outcomes were the responses to the Decisional Conflict Scale and the proportion of correct responses to knowledge questions about stable angina. We also conducted a qualitative analysis on recordings of patient-clinician discussions about treatment planning. The recordings were coded with the OPTION12 instrument for shared decision-making. Two analysts independently assessed the number and types of patient questions and expressions of preferences.

RESULTS

Patient engagement did not differ by health literacy level and was generally low for all patients with respect to OPTION12 scores and the number of questions related to clinical aspects of treatment. Patients with inadequate health literacy had significantly higher decisional conflict. However, the proportion of knowledge questions answered correctly did not differ significantly by health literacy level.

CONCLUSIONS

Patients with inadequate health literacy had greater decisional conflict but no difference in knowledge compared to patients with adequate health literacy. Inadequate health literacy may act as a barrier to communication, but gaps were found in patient engagement and knowledge for patients of all health literacy levels. The recorded patient-clinician encounters and the health literacy measure were valuable resources for conducting research on care delivery.

Enhancing Equitable Access to Assistive Technologies in Canada: Insights from Citizens and Stakeholders

Les besoins en technologies d’assistance augmentent au Canada, mais l’accès à ces technologies est inégal et fragmentaire, ce qui ferait en sorte que des besoins demeureraient non comblés. Cette étude visait à identifier les valeurs et préférences des citoyens concernant les moyens à utiliser pour favoriser un accès équitable aux technologies d’assistance. Elle visait également à impliquer les décideurs politiques, les parties prenantes et les chercheurs dans des discussions afin d’élaborer des actions dans ce domaine. Au printemps 2017, nous avons organisé trois panels de citoyens et un dialogue avec les parties prenantes. Les principales conclusions des panels ont été incluses dans une synthèse qui a été partagée avec les participants du dialogue. Trente-sept citoyens ont participé aux panels et ont souligné l’importance de l’accès à de l’information fiable, d’un accès équitable aux technologies d’assistance (et ce, quelle que soit la capacité de payer), et de la collaboration. Les vingt-deux participants au dialogue ont fait valoir la nécessité d’un cadre d’orientation pour appuyer l’évolution des pratiques dans l’ensemble au pays. Le cadre d’orientation proposé combinerait des politiques et programmes simplifiés incluant la collecte et l’évaluation de données robustes pour appuyer l’innovation et l’imputabilité à travers le pays.

Health Literacy Studies Conducted in Australia: A Scoping Review

Health literacy (HL) is an essential component of various literacies mentioned in the field of health and education, including cultural, technological, media and scientific literacies. It is important for motivating higher consumer engagement. We aimed to review previous studies of HL in Australia to inform future studies, extend current knowledge and further enhance HL. Using search strings, a systematic search of four databases (i.e., MEDLINE; Embase; CINAHL and Eric) was carried out. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) based search strategy led to identification of a total of N = 9696 records, that were further screened for inclusion in the review. The review findings were categorized into three major themes: (1) HL and health numeracy; (2) contrast of: knowledge deficiency, knowledge gained, problems of current health care system and (3) HL measurement methods and its domains. The findings from this scoping review show a dearth of measurement tools with sound psychometric properties for assessing HL. The findings also reveal low levels of HL in consumers which is in turn affecting health-related behaviors, utilization of health services and navigation of the health system. More recent developments have tried to integrate vital aspects, including introduction of applications to increase HL and exploring HL in Aboriginal communities.

Beginning with high value care in mind: A scoping review and toolkit to support the content, delivery, measurement, and sustainment of high value care

OBJECTIVE

To create a shared vision for the content, delivery, measurement, and sustainment of patient-centered high value care.

METHODS

We performed a scoping review and translated findings into toolkit for system leaders. For our scoping review, we searched Medline, 2005-November 2015, for literature on patient-centered care (PCC) and its relationship to a high value care change model. We supplemented searches with key author, Google Scholar, and key website searches. One author reviewed all titles, abstracts, and articles for inclusion; another reviewed a random 20%. To develop our toolkit, we translated evidence into simple, actionable briefs on key topics and added resources. We then iteratively circulated briefs and the overall toolkit to potential users, making updates as needed.

RESULTS

In our scoping review, we found multiple interventions and measures to support the components of PCC and our change model. We found little on the overall effects of PCC or how PCC creates value. Potential users reported our toolkit was simple, understandable, thorough, timely, and likely to be globally useful.

CONCLUSIONS

Considerable evidence supports patient-centered high value care and a toolkit garnered enthusiasm.

PRACTICE IMPLICATIONS

The toolkit is ready for use, but needs comparison to other approaches.

The relationship between health literacy and perceived shared decision making in patients with breast cancer

OBJECTIVES

We explored the relationship between patient-perceived shared decision making (SDM) and three domains of health literacy (HL) in patients with breast cancer.

METHODS

In this cross-sectional study, we prospectively recruited a convenience sample of 511 breast cancer patients from 3 hospitals in Taiwan. Patients completed questionnaires about HL and perceived SDM in a recent consultation. Sequential regressions, controlling for International Classification of Functioning, Disability and Health (ICF)-related factors) were conducted. Interactions of each HL domain with age or education were also assessed for the relationship with perceived SDM.

RESULTS

Higher scores in the HL domains of healthcare and disease prevention, but lower scores in the health promotion domain, were significantly associated with a higher perceived level of SDM after controlling for ICF-related factors (R² = 33.44%). The association of SDM with two domains of HL varied with age, while the relationship between the 3 HL domains and SDM differed across education levels.

CONCLUSION

Each HL domain was significantly associated with perceived SDM after controlling for the ICF-related factors and across different age- and education-stratifications.

PRACTICE IMPLICATIONS

Clinicians should be cognizant of patients' HL levels and incorporate HL best practices into consultations and interactions with patients with breast cancer to facilitate SDM.

IUHPE Position Statement on Health Literacy: a practical vision for a health literate world

The International Union for Health Promotion and Education (IUHPE) Position Statement on Health Literacy provides an overview of existing evidence and continuing debate on health literacy. Developed by the IUHPE Global Working Group on Health Literacy, including experts from around the globe, the Statement provides a basis for discussion and advocacy, by and with IUHPE, both within the health promotion community, and among stakeholders and partners in health promotion. The Statement offers a detailed introduction to the concept of health literacy, calling for global action to improve health literacy in populations. It positions health literacy as an important and modifiable social determinant of health, that plays a significant role in broadly-based strategies for health promotion. The Statement emphasises the necessity of a systems approach to health literacy, underpinned by global, national, regional and local policies. It summarises key evidence to guide practice and policy development, recognising the importance of continued investment in intervention research, in professional and consumer capacity building, and in the transfer of research findings into frontline health promotion practice. In summary, health literacy is understood as an important cross-cutting issue in health promotion throughout the lifespan, which has practical application in guiding clinical practice, public health interventions and public policy for the advancement of global health.

Preferences of Patients and Pharmacists with Regard to the Management of Drug-Drug Interactions: A Choice-Based Conjoint Analysis

Introduction

The management of drug–drug interactions (DDIs) is a complex process in which risk–benefit assessments should be combined with the patient’s perspective.

Objective

The aim of this study was to determine patients’ and pharmacists’ preferences regarding DDI management.

Methods

We conducted a choice-based conjoint survey about a fictitious DDI concerning the combination of a cardiovascular drug and an antibiotic for pneumonia. Patients and pharmacists had to choose 12 times between two management options. The options were described by five attributes, including risk, benefit and practical consequences. Each attribute could have two different levels, which were varied over the choice tasks. Latent class analysis was used to identify potential classes of respondents with distinct patterns of similar preferences.

Results

In total, 298 patients and 178 pharmacists completed the questionnaire. The latent class model for both patients and pharmacists resulted in three classes. For patients, in one class the most importance was attached to avoiding switch of medication (class probability 20%), in a second class to fewer adverse events (41%), and in a third class to blood sampling (39%). For pharmacists, again one class attached the highest importance to avoiding switch of medication (31%). The other classes gave priority to curing pneumonia (31%) and avoiding blood sampling (38%).

Conclusion

The results showed diverging preferences regarding DDI management among both patients and pharmacists. Different groups attached different value to risk and benefit versus practical considerations. Awareness of existing variability in preferences among and between pharmacists and patients is a step towards shared decision making in DDI management.

Aspects influencing patients' preferences for the management of drug-drug interactions: A focus group study

OBJECTIVE

The management of drug-drug interactions (DDIs) involves a complex risk-benefit assessment, in which patients' preferences should be taken into account. The aim of this study was to examine the aspects influencing patients' preferences with regard to DDI management options.

METHODS

A qualitative study consisting of five focus groups with patients chronically using cardiovascular drugs was conducted. Key questions concerned preferences regarding DDI management options for a provided fictitious DDI. Thematic analysis of the verbatim transcripts was performed.

RESULTS

Despite their limited knowledge with respect to DDIs, patients easily chose a management option for the presented DDI. When additional information was provided, preferences showed to be fluid. Ten interdependent aspects influencing preferences were derived from patients' argumentations: risk perception, fear, acceptance of uncertainty, openness to change, willingness to take risk, trust in health care professional, financial & practical burdens, health condition, experience, and knowledge & assumptions.

CONCLUSION

Patients' preferences regarding DDI management options were often determined by provided information. Preferences were dependent on an interplay of diverse aspects.

PRACTICE IMPLICATIONS

Tailored provision of information and individualized counseling is needed for active patient involvement in DDI decision making.

Adult patient decision-making regarding implantation of complex cardiac devices: a scoping review

BACKGROUND

Complex cardiac rhythm management device (CRMD) therapy provides an important treatment option for people at risk of sudden cardiac death. Despite the survival benefit, device implantation is associated with significant physical and psychosocial concerns presenting considerable challenges for the decision-making process surrounding CRMD implantation for patients and physicians.

AIMS

The purpose of this scoping review was to explore what is known about how adult (>16 years) patients make decisions regarding implantation of CRMD therapy.

METHODS

Published, peer reviewed, English language studies from 2000 to 2016 were identified in a search across eight healthcare databases. Eligible studies were concerned with patient decision-making for first time device implantation. Quality assessment was completed using the mixed methods appraisal tool for all studies meeting the inclusion criteria.

RESULTS

The findings of eight qualitative and seven quantitative studies, including patients who accepted or declined primary or secondary sudden cardiac death prevention devices, were clustered into two themes: knowledge acquisition and the process of decision-making, exposing similarities and distinctions with the treatment decision-making literature.

CONCLUSION

The review revealed some insight in to the way patients approach decision-making but also exposed a lack of clarity and research activity specific to CRMD patients. Further research is recommended to support the development and application of targeted decision support mechanisms.

Assessing the predictive power of psychological empowerment and health literacy for older patients' participation in health care: a cross-sectional population-based study

BACKGROUND

Research has confirmed a positive link between patient involvement in decision-making and improvements in health outcomes. The objective of this study was to examine the roles of psychological empowerment and health literacy on the elderly's willingness to engage in treatment decisions.

METHODS

A self-administered questionnaire was completed by a randomly selected sample of Swiss adults aged 65-80 years old (N = 826). Multivariate logistic regression was applied to determine the contribution of health literacy, psychological empowerment, and trust in physician on participants' preference to be active, collaborative or passive in decision-making.

RESULTS

Most of the survey respondents preferred some participation in dealing with health related decisions (collaborative: 51%, and active: 35.6%). More than two-thirds of the sample was satisfied with their current involvement in medical decision-making (72.7%). Roughly one-fifth (18.8%) wished to attain a more active engagement than currently experienced, and the remainder of the sample preferred the opposite (8.5%). Due to higher reported levels of psychological empowerment and health literacy, Swiss-German seniors significantly preferred and assumed higher participation in medical decisions than Swiss-Italians. Psychological empowerment correlated with older adults' preferred and perceived involvement in medical decision-making. However, health literacy only predicted actual involvement in the last treatment decision that had to be made, differentiating only the active from the passive involvement group. Additionally, this research showed that health literacy mediated the relationship between psychological empowerment and the actual involvement in the last treatment decision that had to be made by the participant. Trust in physician and age appeared to be barriers to involvement, whereas education served as a facilitator.

CONCLUSIONS

As older adults' health literacy plays a role in individuals' willingness to attain an active role in health care decision-making, public health efforts should aim at developing programs and appropriate information that facilitate this process, especially for individuals with moderate or lower levels of health literacy. The current investigation showed that adequate health literacy levels are essential (but not sufficient) in order to reach higher rates of participation in the healthcare context. This research complements past evidence by adding knowledge on the psychosocial antecedents, and their combined effects on patients' involvement in healthcare.

Understanding scoping reviews: Definition, purpose, and process

BACKGROUND/PURPOSE

Scoping review design represents a methodology that allows assessment of emerging evidence, as well as a first step in research development. Despite its increasing use, to date no article reflecting use of scoping review methodology has been submitted for review at JAANP. The purpose of this article is to provide detailed information on scoping reviews, including definition, related processes, and uses, and discuss the relationship to nurse practitioner (NP) practice, policy, education, and research. The longer-term goal is that NPs will understand the related techniques, consider the methodology as a viable one for NP scholarship, and bring related reports to the forefront of NP publications.

METHODS

This manuscript represents a brief report. Processes to develop the brief include detailed search and review of scoping review literature in CINAHL and PubMed. Both methodologic reports and reviews were included. Definitions and uses of scoping reviews were reviewed.

CONCLUSION

The definition and process of scoping review are evolving. Although there is controversy regarding the methodology, there is increasing visibility of scoping review methodology in the published literature since the year 2000, with over 500 published reviews currently available.

IMPLICATIONS FOR PRACTICE

A well-executed scoping review has potential to inform NP practice, policy, education, and research.

Role of Psychosocial Factors and Health Literacy in Pregnant Women's Intention to Use a Decision Aid for Down Syndrome Screening: A Theory-Based Web Survey

BACKGROUND

Deciding about undergoing prenatal screening is difficult, as it entails risks, potential loss and regrets, and challenges to personal values. Shared decision making and decision aids (DAs) can help pregnant women give informed and values-based consent or refusal to prenatal screening, but little is known about factors influencing the use of DAs.

OBJECTIVE

The objective of this study was to identify the influence of psychosocial factors on pregnant women's intention to use a DA for prenatal screening for Down syndrome (DS). We also added health literacy variables to explore their influence on pregnant women's intention.

METHODS

We conducted a survey of pregnant women in the province of Quebec (Canada) using a Web panel. Eligibility criteria included age >18 years, >16 weeks pregnant, low-risk pregnancy, and having decided about prenatal screening for the current pregnancy. We collected data based on an extended version of the Theory of Planned Behavior assessing 7 psychosocial constructs (intention, attitude, anticipated regret, subjective norm, descriptive norm, moral norm, and perceived control), 3 related sets of beliefs (behavioral, normative, and control beliefs), 4 health literacy variables, and sociodemographics. Eligible women watched a video depicting the behavior of interest before completing a Web-based questionnaire. We performed descriptive, bivariate, and ordinal logistic regression analyses.

RESULTS

Of the 383 eligible pregnant women who agreed to participate, 350 pregnant women completed the Web-based questionnaire and 346 were retained for analysis (completion rate 350/383, 91.4%; mean age 30.1, SD 4.3, years). In order of importance, factors influencing intention to use a DA for prenatal screening for DS were attitude (odds ratio, OR, 9.16, 95% CI 4.02-20.85), moral norm (OR 7.97, 95% CI 4.49-14.14), descriptive norm (OR 2.83, 95% CI 1.63-4.92), and anticipated regret (OR 2.43, 95% CI 1.71-3.46). Specific attitudinal beliefs significantly related to intention were that using a DA would reassure them (OR 2.55, 95% CI 1.73-4.01), facilitate their reflections with their spouse (OR 1.55, 95% CI 1.05-2.29), and let them know about the advantages of doing or not doing the test (OR 1.53, 95% CI 1.05-2.24). Health literacy did not add to the predictive power of our model (P values range .43-.92).

CONCLUSIONS

Implementation interventions targeting the use of a DA for prenatal screening for DS by pregnant women should address a number of modifiable factors, especially by introducing the advantages of using the DA (attitude), informing pregnant women that they might regret not using it (anticipated regret), and presenting the use of DAs as a common practice (descriptive norm). However, interventions on moral norms related to the use of DA should be treated with caution. Further studies that include populations with low health literacy are needed before decisive claims can be made.

Health literacy in pregnant women facing prenatal screening may explain their intention to use a patient decision aid: a short report

BACKGROUND

It has been suggested that health literacy may impact the use of decision aids (DAs) among patients facing difficult decisions. Embedded in the pilot test of a questionnaire, this study aimed to measure the association between health literacy and pregnant women's intention to use a DA to decide about prenatal screening. We recruited a convenience sample of 45 pregnant women in three clinical sites (family practice teaching unit, birthing center and obstetrical ambulatory care clinic). We asked participating women to complete a self-administered questionnaire assessing their intention to use a DA to decide about prenatal screening and assessed their health literacy levels using one subjective and two objective scales.

RESULTS

Two of the three scales discriminated between levels of health literacy (three numeracy questions and three health literacy questions). We found a positive correlation between pregnant women's intention to use a DA and subjective health literacy (Spearman coefficient, Rho 0.32, P = 0.04) but not objective health literacy (Spearman coefficient, Rho 0.07, P = 0.65). Hence subjective health literacy may affect the intention to use a DA among pregnant women facing a decision about prenatal screening.

CONCLUSION

Special attention should be given to pregnant women with lower health literacy levels to increase their intention to use a DA and ensure that every pregnant women can give informed and value-based consent to prenatal screening.

“These patients look lost” – Community pharmacy staff’s identification and support of patients with limited health literacy

Objective

To date, routine use of health literacy assessment in clinical settings is limited. The objective of this study was to explore if community pharmacy staff can identify patients with limited health literacy, how they identify patients and how they support patients to improve medication use. In addition, perceived barriers in providing care for patients with limited health literacy were assessed.

Methods

Structured face-to-face interviews with pharmacy staff were performed in 27 community pharmacies. Questions concerned pharmacy staff’s experiences with limited health literacy during their work, e.g. recognition of patients, communication strategies and possible interventions for this patient group to improve medication use.

Key findings

Results from 74 interviews were included for analysis. Sixty-eight interviewees (92%) mentioned to identify patients with limited health literacy during their work, mostly based on intuition. Suggested strategies to improve medication use included tailored education and information, intensive support or use of aids such as a multidose drug dispensing system. Pharmacy staff indicated lack of time as a barrier to provide tailored pharmaceutical care.

Conclusions

Most participants mentioned to recognize patients with limited health literacy merely on intuition or based on certain patient characteristics. Thus, an unknown number of patients with limited health literacy might be missed. This underlines the need to create more awareness of health literacy among pharmacy professionals. Moreover, training of pharmacy staff and use of aids to identify limited health literacy may help to identify more patients who need additional counselling.

Empirical relationships between numeracy and treatment decision making: A scoping review of the literature

OBJECTIVES

To determine what is known from the existing literature about empirical relationships between numeracy and the three stages of the treatment decision making process (information exchange, deliberation, and deciding on the treatment to implement). We also examined if, and how, numeracy was mentioned in relation to health literacy.

METHODS

A search of four databases returned 2772 records. After de-duplication and three levels of relevance screening, 38 primary studies were included in this review.

RESULTS

Relationships between numeracy and the information exchange stage have received greater attention than relationships between numeracy and the deliberation and deciding on the treatment to implement stages. The lack of overlap in the empirical relationships examined in studies, the measure(s) of numeracy used, and the characteristics of study populations, made findings difficult to compare. Multiple knowledge gaps and measurement-related problems were identified. Numeracy and health literacy have largely been treated as separate concepts.

CONCLUSION

More research is needed to better understand the importance of numeracy and health literacy to treatment decision making.

PRACTICE IMPLICATIONS

Decision aids designed for patients with different levels of health literacy may not meet the needs of patients with different levels of numeracy. The numeracy skills of health professionals require attention.

Cyberchondria: Parsing Health Anxiety From Online Behavior

BACKGROUND

Individuals with questions about their health often turn to the Internet for information about their symptoms, but the degree to which health anxiety is related to online checking, and clinical variables, remains unclear. The clinical profiles of highly anxious Internet checkers, and the relationship to checking behavior itself, have not previously been reported.

OBJECTIVE

In this article, we test the hypothesis, derived from cognitive-behavioral models, that individuals with higher levels of illness anxiety would recall having experienced worsening anxiety after reassurance-seeking on the Internet.

METHOD

Data from 731 volunteers who endorsed engaging in online symptom-searching were collected using an online questionnaire. Severity of health anxiety was assessed with the Whiteley Index, functional impairment with the Sheehan Disability Scale, and distress recall during and after searching with a modified version of the Clinician׳s Global Impairment scale. Multiple regression analyses were conducted to determine variables contributing to distress during and after Internet checking.

RESULTS

Severity of illness anxiety on the Whiteley Index was the strongest predictor of increase in anxiety associated with, and consequent to, online symptom-searching. Individuals with high illness anxiety recalled feeling worse after online symptom-checking, whereas those with low illness anxiety recalled relief. Longer-duration online health-related use was associated with increased functional impairment, less education, and increased anxiety during and after checking.

CONCLUSION

Because individuals with moderate-high levels of illness anxiety recall experiencing more anxiety during and after searching, such searching may be detrimental to their health. If replicated in controlled experimental settings, this would suggest that individuals with illness anxiety should be advised to avoid using the Internet for illness-related information.

Assessment of the Chinese Resident Health Literacy Scale in a population-based sample in South China

Background

A national health literacy scale was developed in China in 2012, though no studies have validated it. In this investigation, we assessed the reliability, construct validity, and measurement invariance of that scale.

Methods

A population-based sample of 3731 participants in Hunan Province was used to validate the Chinese Resident Health Literacy Scale based on item response theory and classical test theory (including split-half coefficient, Cronbach’s alpha, and confirmatory factor analysis). Measurement invariance was examined by differential item functioning.

Results

The overall Cronbach’s alpha of the scale was 0.95 and Spearman-Brown coefficient 0.94. Confirmatory factor analysis showed that the test measured a unidimensional construct with three highly correlated factors. Highest discrimination was found among participants with limited to moderate health literacy. In all, 64 items were selected from the original scale based on factor loading, Pearson’s correlation coefficient, and discrimination and difficulty parameters in item response theory. Measurement invariance was significant but slight. According to the two-level linear model, health literacy was associated with education level, occupation, and income.

Conclusions

The 2012 national health literacy scale was validated, and 64 items were selected based on classical test theory and item response theory. The revised version of the scale has strong psychometric properties with minor measurement invariance.
