The Relationship Between Health Management and Information Behavior Over Time: A Study of the Illness Journeys of People Living With Fibromyalgia

Mobile App Use among Persons with Fibromyalgia: A Cross-sectional Survey

Persons with fibromyalgia experience a diverse set of symptoms. Recommendations for management generally focus on multidisciplinary approaches involving multiple modalities. Mobile apps can be an essential component for self-management, yet little is known about how persons with fibromyalgia use mobile apps for health-related purposes. A cross-sectional survey (N = 663) was conducted to understand the real-world use of apps among persons with fibromyalgia. The survey included 2 main foci: 1) eHealth literacy and use of information sources, and 2) mobile app use patterns and preferences for health-related purposes, including the types of apps used and usage characteristics of apps currently in use, as well as those that had been discontinued. Respondents' average eHealth literacy as measured by eHealth Literacy Scale (eHEALS) was 31.4 (SD = 7.1), and they utilized diverse information sources. Approximately two-thirds of the sample used mobile apps; the remaining one-third did not. Diverse health management needs were represented in the apps reported, including scheduling/time management, notetaking, fitness, and wellness. Compared to apps that had been discontinued, participants rated apps that they still used higher in terms of ease of use and used them more frequently. Reasons for discontinuing app use included issues with privacy, the effort required, lack of interest, and lack of perceived quality. Other reasons for app nonuse were lack of awareness and how-to knowledge, indicating that disseminating information about apps and addressing other barriers, such as providing user support, are critical to increasing uptake. These study findings can inform both app design and dissemination. PERSPECTIVE: This article presents how persons with fibromyalgia use mobile apps to manage their health. The findings could inform the development of digital interventions or programs for this population.

Assessment of health literacy in patients with polycystic ovary syndrome and its relationship with health behaviours: a cross-sectional study

OBJECTIVE

Healthy behaviours are important for people with polycystic ovary syndrome (PCOS). However, adopting and maintaining lifestyle changes involves a complex set of behavioural changes, which most patients fail to adhere to. The current research on health literacy, which includes individual and social skills needed in health self-management, in patients with PCOS is limited. Therefore, this study aimed to explore health literacy, health behaviours and the relationship between the two to expand research on PCOS management.

DESIGN

Cross-sectional study.

SETTING

A gynaecological outpatient clinic.

PARTICIPANTS

A total of 286 patients with PCOS (≥18 years, diagnosed via Rotterdam criteria, able to self-report and give informed consent) were recruited from March to June 2022.

OUTCOME MEASURES

Health literacy and health behaviours in patients with PCOS were assessed using the Health Literacy Management Scale and the Health Promoting Lifestyle Profile (Chinese version). Multiple logistic regression was used to analyse the factors influencing health literacy, and linear regression to assess the relationship between health literacy and health behaviours, with an F-significance test; p<0.05 was considered statistically significant.

RESULTS

Overall, most patients with PCOS had insufficient health literacy (55.9%). The influencing factors of health literacy in patients with PCOS were age (β=0.154, p<0.05), Body Mass Index (β=-0.140, p<0.05), income (β=1.228, p<0.05), duration of illness (β=0.110, p<0.05) and educational level (β=1.552, p<0.05). Moreover, 40.6% of patients with poor health behaviours, and 31.8% with moderate health behaviours, needed to improve their health behaviours. Health literacy was positively correlated with health behaviours in patients with PCOS (r=0.473, p<0.05).

CONCLUSION

The positive correlation between health literacy and health behaviour in patients with PCOS indicates that promoting health literacy in future treatment and management of PCOS may be beneficial.

Fibromyalgia pain management effectiveness from the patient perspective: a qualitative evidence synthesis

PURPOSE

This qualitative evidence synthesis aimed to identify and integrate findings where adults with fibromyalgia discussed how they managed their pain, and their perceptions of prescribed treatments from healthcare professionals.

MATERIALS AND METHODS

A comprehensive search strategy was implemented in PubMed, Scopus, ISI Web of Science, and Cinahl Plus databases. The GRADE-CERQual framework was used to evaluate the findings confidence. The findings were analyzed using an inductive thematic analysis approach.

RESULTS

A total of 35 studies (N = 728) were included. The confidence in the findings ranged from high to low confidence. Patients with fibromyalgia often do not benefit from seeking medical attention due to provider stigma, and have varying views on medication effectiveness commonly reporting feeling like "walking chemists." They find mixed effects from exercise, and consider psychological support essential, although the benefits of cognitive-behavioral therapy were controversial. Combining cognitive-behavioral therapy with physical exercise appears more effective, while natural and complementary therapies have short-term benefits and high costs.

CONCLUSIONS

Pain management is a source for frustration and an unmet need for patients with fibromyalgia. The current findings provide crucial insight for providers and researchers; and support the need for fibromyalgia phenotyping and precision medicine approaches to pain management.Implications for RehabilitationChronic widespread pain is the defining feature of fibromyalgia, yet pain reduction is often an unmet need for these individuals.The lack of effective treatments resulting in long-term relief proves frustrating for patients and healthcare providers.Rehabilitation professional should consider the unique insight into this complex, heterogeneous condition that this qualitative synthesis provides to better understand their patient's perspective on pain management.Given the differing perspectives on pain treatment approaches individuals with fibromyalgia report, providers should discuss with each patient their current strategies and take a patient-centered, individualized approach to form an effective treatment plan.

"It's All in Your Head": A Meta-Synthesis of Qualitative Research About Disenfranchising Talk Experienced by Female Patients with Chronic Overlapping Pain Conditions

Interactions between female patients with chronic pain and their medical providers in which providers question or contest the "realness" or nature of their illness experience (e.g. "It's all in your head") have been reported extensively in the extant qualitative literature, particularly for poorly understood ("contested") chronic pain syndromes. Many terms have been offered to describe this talk (e.g. invalidating, dismissive), resulting in conceptual fragmentation and isolated silos of research which together report about one communicative phenomenon. To rectify this fragmentation, the present study offers a meta-synthesis which explores, analyzes, and integrates the findings of 82 qualitative interview studies representing the patient-provider communication experiences of 2,434 female patients living with one or more of 10 chronic overlapping pain conditions (COPCs). COPCs are costly, gendered, and poorly understood. From the meta-synthesis, three key concepts are identified: (1) Functions of disenfranchising talk: Discrediting, silencing, and stereotyping; (2) Effects of disenfranchising talk: Harmed agency, credibility; access to care, support, and resources; and perception of patient-provider relationship; and (3) Responses to disenfranchising talk: Submission, critique, and resistance. Findings confirm the centrality of gender in the experience of disenfranchising talk, underscore the need to adopt an intersectional approach to the study of this talk along additional axes of race and class, and offer heuristic value toward conceptually unifying research about female COPC patients' experiences of disenfranchising talk from providers.

Social Support in Online Peer Groups for Celiac Disease

Abstract. Background: While there is considerable evidence for the positive effects of onsite peer support on health outcomes, few studies have addressed the impact of online peer support. Aims: This study differentiates between emotional (ES) and informational (IS) online peer support for people with celiac disease. We hypothesize that receiving ES and IS positively correlates with self-reported well-being and dietary compliance and that these relations would be moderated by the duration of illness. Method: We used a correlational, cross-sectional design ( N = 369). Results: Both functions of support were positively related to well-being and dietary compliance. The strengths of the positive relationships between ES and both outcomes and IS and well-being were independent of the duration of illness. IS was significantly positively related to dietary compliance among participants with a longer duration of illness, but unrelated among participants with a shorter duration. Limitations: Due to the correlational design, we cannot infer causality. Conclusion: Our findings advance the understanding of online support in contexts where proper self-management is crucial for health outcomes.

Potential Misfortunes in 'Making Sense': A Cross-Sectional Study in People with Chronic Pain

Making sense of one's circumstances is normally regarded as helpful, including in the context of chronic pain. However, sense-making may be associated with adverse impacts in daily functioning. To better understand the functions of sense-making, the objective of the current study was to develop, validate, and preliminarily examine a measure of potentially helpful and unhelpful forms of sense-making behavior in people seeking treatment for chronic pain. This measure is called the Sense Making Questionnaire (SMQ). Research participants included 451 adults consecutively attending a specialty interdisciplinary treatment for chronic pain. Data for this study derived from a standard set of measures participants completed prior to treatment. Exploratory Factor Analysis (EFA) produced a 3-factor solution based on 15 items, including Avoidance of Incoherence, Overthinking, and Functional Coherence. The first 2 of these factors and the total achieved adequate internal consistency. Construct validity of the SMQ scores was supported by significant correlations with measures of pain acceptance, committed action, cognitive fusion, and intolerance of uncertainty. The SMQ total score correlated significantly with pain interference, r = .23, depression, r = .41, and work and social adjustment, r = .30, all P < .001. In multiple regression analyses the total score also significantly predicted depression after age, gender, education, pain duration, pain intensity, and pain acceptance were statistically controlled, and it accounted for an additional 8.0% in explained variance. It appears that there is a distinction between literal coherence and functional coherence. In some situations, it may benefit people with chronic pain to shift focus from efforts to make literal sense of pain and instead to keep the focus on taking effective action even if this does not appear at first to make sense. PERSPECTIVE: This study in people seeking treatment for chronic pain includes development of a measure of behavior patterns related to making sense in chronic pain. It shows that sometimes these behavior patterns can be ineffective, as they appear negatively associated with emotional, physical, and social functioning.

Internet-Based Information Behavior After Pregnancy Loss: Interview Study

BACKGROUND

Information behavior describes all human behaviors in relation to information. Individuals experiencing disruption or stigma often use internet-based tools and spaces to meet their associated information needs. One such context is pregnancy loss, which, although impactful and common, has been absent from much of feminist and reproductive health and information behavior scholarship. By understanding information behavior after pregnancy loss and accounting for it in designing internet-based information spaces, we can take a meaningful step toward countering the stigma and silence that many who experience such loss endure, facilitate coping, and make space for diverse pregnancy narratives in our society.

OBJECTIVE

This study's objective is to provide a characterization of internet-based information behavior after pregnancy loss.

METHODS

We examined internet-based information behavior after pregnancy loss through 9 in-depth interviews with individuals residing in the United States. We analyzed the data by using open and axial coding.

RESULTS

We identified the following three themes in relation to participants' information behavior in internet-based spaces: needed information types, information-related concerns, and information outcomes. We drew from information behavior frameworks to interpret the processes and concerns described by participants as they moved from recognizing information needs to searching for information and to using information and experiencing outcomes. Specifically, we aligned these themes with information use concepts from the information behavior literature-information search, knowledge construction, information production, information application, and information effects. Participants' main concerns centered on being able to easily find information (ie, searchability), particularly on topics that had already been covered (ie, persistence), and, once found, being able to assess the information for its relevance, helpfulness, and credibility (ie, assessability). We suggest the following design implications that support health information behavior: assessability, persistence, and searchability.

CONCLUSIONS

We examined internet-based information behavior in the context of pregnancy loss, an important yet silenced reproductive health experience. Owing to the prevalence of information seeking during pregnancy, we advocate that generic pregnancy-related information spaces should address the needs related to pregnancy loss that we identified in addition to spaces dedicated to pregnancy loss. Such a shift could not only support those who use these spaces to manage pregnancies and then experience a loss but also help combat the silence and stigma associated with loss and the linear and normative narrative by which pregnancies are often represented.

Preferences and Experiences of People with Chronic Illness in Using Different Sources of Health Information: Results of a Mixed-Methods Study

Background: People with chronic illness are particularly dependent on adequate health literacy (HL), but often report difficulties in accessing, understanding, appraising, and applying health information. To strengthen the HL of people with chronic illness, in-depth knowledge about how they deal with health information is crucial. Methods: To this end, quantitative data from the Second Health Literacy Survey Germany (HLS-GER 2) and qualitative data from seven focus group discussions were used to examine the interest in health information, preferred sources of information as well as experiences and challenges with information management among people with chronic illness. Results: The results show that people with chronic illness have a great interest in health information and use very different sources of health information, preferring personal information from physicians most. The results also point to several challenges in health information management that seem to be influenced by the illness duration as well as by the experiences made with the respective sources. Conclusions: Overall, the study provides important starting points for intervention development for the provision and communication of health-related information, but also to research on health information behavior and HL.

Recommendations by the Spanish Society of Rheumatology on Fibromyalgia. Part 1: Diagnosis and treatment

OBJECTIVE

To prevent the impairment of fibromyalgia patients due to harmful actions in daily clinical practice that are potentially avoidable.

METHODS

A multidisciplinary team identified the main areas of interest and carried out an analysis of scientific evidence and established recommendations based on the evidence and "formal evaluation" or "reasoned judgment" qualitative analysis techniques.

RESULTS

A total of 39 recommendations address diagnosis, unsafe or ineffective treatment interventions and patient and healthcare workers' education. This part I shows the first 27 recommendations on the first 2 areas.

CONCLUSIONS

Establishing a diagnosis improves the patient's coping with the disease and reduces healthcare costs. NSAIDs, strong opioids and benzodiazepines should be avoided due to side effects. There is no good evidence to justify the association of several drugs. There is also no good evidence to recommend any complementary medicine. Surgeries show a greater number of complications and a lower degree of patient satisfaction and therefore should be avoided if the surgical indication is not clearly established.

Human information behavior during the Covid-19 health crisis. A literature review

The research carried out on human information behavior (HIB) during the Covid-19 health crisis was reviewed, with the premise that HIB and information practices allow humans to adapt to the changing circumstances of existence. A literature search was run on the LISTA and Google Scholar databases from middle March 2020 up to the end of March 2021. After filtering retrieved results, 52 studies were selected. Results are summarized into seven main themes, including the use of traditional and social media, infoveillance of search engines and social media activity, misinformation, disinformation and infodemics, and uncertainty and emotions. Results point to the need to carry out additional research in specific contexts and addressing vulnerable and marginalized groups. Further areas of inquiry include the interplay of emotions, knowledge and behaviors during the information seeking process, a better understanding of local knowledge and experiential knowledge, and the need to comprehend the limitations of ICT.

Factors in the Building of Effective Patient-Provider Relationships in the Context of Fibromyalgia

Objective

Fibromyalgia patients face particular challenges in building relationships with health care providers. In this study, we examine, from patients’ perspectives, factors that influence the formation of effective patient–provider relationships.

Design

This research employed a qualitative approach to analyze data collected from a study that employed semistructured interviews.

Methods

Multiple methods were used to recruit 23 fibromyalgia patients for interviews. Semistructured interviews were conducted to explore how participants’ information behaviors, including their communication with and relationships to providers, changed over time. The interview data were analyzed using a qualitative analytic method based on interpretative phenomenological analysis and constructivist grounded theory.

Results

We identified three important factors that influenced the building of effective relationships: patients and providers’ interactions involving information, identifying health care providers that fit patients’ needs, and realizing shared responsibilities. With regard to information, we described three important themes: information gaps, providers as educators/facilitators, and collaborative information behavior.

Conclusions

Understanding of the key elements of relationship development between patients and providers can be utilized in various ways to improve clinical care. First, the knowledge gained in this study can inform the design of patient education materials that assist patients to identify providers that fit their needs, prepare for consultations, and develop realistic expectations for providers. The findings of this study can also inform the design of resources and tools to enable clinicians to communicate and relate better with their patients.

Patient Perspectives to Inform a Health Literacy Educational Program: A Systematic Review and Thematic Synthesis of Qualitative Studies

Patient-centred care is tailored to the needs of patients and is necessary for better health outcomes, especially for individuals with limited health literacy (LHL). However, its implementation remains challenging. The key to effectively address patient-centred care is to include perspectives of patients with LHL within the curricula of (future) healthcare providers (HCP). This systematic review aimed to explore and synthesize evidence on the needs, experiences and preferences of patients with LHL and to inform an existing educational framework. We searched three databases: PsychInfo, Medline and Cinahl, and extracted 798 articles. One-hundred and three articles met the inclusion criteria. After data extraction and thematic synthesis, key themes were identified. Patients with LHL and chronic diseases encounter multiple problems in the care process, which are often related to a lack of person-centeredness. Patient perspectives were categorized into four key themes: (1) Support system; (2) Patient self-management; (3) Capacities of HCPs; (4) Barriers in healthcare systems. "Cultural sensitivity" and "eHealth" were identified as recurring themes. A set of learning outcomes for (future) HCPs was developed based on our findings. The perspectives of patients with LHL provided valuable input for a comprehensive and person-centred educational framework that can enhance the relevance and quality of education for (future) HCPs, and contribute to better person-centred care for patients with LHL.

Mining and standardizing chinese consumer health terms

Background

Health professionals and consumers use different terms to express medical events or concerns, which makes the communication barriers between the professionals and consumers. This may lead to bias in the diagnosis or treatment due to the misunderstanding or incomplete understanding. To solve the issue, a consumer health vocabulary was developed to map the consumer-used health terms to professional-used medical terms.

Methods

In this study, we extracted Chinese consumer health terms from both online health forum and patient education monographs, and manually mapped them to medical terms used by professionals (terms in medical thesauri or in medical books). To ensure the above annotation quality, we developed annotation guidelines.

Results

We applied our method to extract consumer-used disease terms in endocrinology, cardiology, gastroenterology and dermatology. In this study, we identified 1349 medical mentions from 8436 questions posted in an online health forum and 1428 articles for patient education monographs. After manual annotation and review, we released 1036 Chinese consumer health terms with mapping to 480 medical terms. Four annotators worked on the manual annotation work following the Chinese consumer health term annotation guidelines. Their average inter-annotator agreement (IAA) score was 93.91% ensuring high consistency of the released terms.

Conclusions

We extracted Chinese consumer health terms from online forum and patient education monographs, and mapped them to medical terms used by professionals. Manual annotation efforts have been made for term annotating and mapping. Our study may contribute to the Chinese consumer health vocabulary construction. In addition, our annotated corpus, both the contexts of consumer health terms and consumer-professional term mapping, would be a useful resource for automatic methodology development. The dataset of the Chinese consumer health terms (CHT) is publicly available at http://www.phoc.org.cn/cht/.

Characterizing Websites That Provide Information About Complementary and Integrative Health: Systematic Search and Evaluation of Five Domains

Background

In recent years, there has been an increase in the utilization of complementary and integrative health (CIH) care, and an increase in information-seeking behavior focused on CIH. Thus, understanding the quality of CIH information that is available on the internet is imperative. Although there have been a limited number of studies evaluating the quality of websites providing information about specific CIH-related topics, a broad evaluation of CIH websites has not been conducted.

Objective

This study was designed to fill that gap. We set out to assess website quality in 5 CIH domains: (1) acupuncture, (2) homeopathy, (3) massage, (4) reiki, and (5) yoga. This study aimed to 1) characterize the websites by type and quality; 2) evaluate website characteristics which may affect readers’ perceptions, specifically message content, structural features, and presentation style, and 3) investigate the extent to which harms, benefits and purposes of use are stated on websites.

Methods

This study employed a systematic search strategy to identify websites in each of the target domains to be evaluated. The websites were then classified by type, and a set of checklists focusing on quality, message content, structural features, and presentation style was used to evaluate the websites. Lastly, we performed content analysis to identify harms, benefits, and perceived purposes of use.

Results

There were similarities across domains regarding their overall quality and their message content. Across all domains, a high proportion of websites received strong scores in terms of ownership, currency, interactivity and navigability. Scores were more variable concerning authorship, balanced presentation of information and the use of sources of information. However, there were differences regarding their structural features and presentation style. Acupuncture and reiki sites tended to include more external links, and yoga, fewer. There was variation across domains in the extent to which the websites contained domain-specific terminology. Websites tended to provide an extensive list of potential benefits, while reporting of harms was scarce.

Conclusions

This is the first study to perform a multidimensional assessment of websites in multiple CIH domains. This review showed that while there are similarities among websites of different CIH domains, there are also differences. The diverse distribution of website types suggests that, regardless of CIH domain, the public encounters information through many different types of media, and it would be useful to consider how the presentation of this content may differ depending on the medium. The characteristics for which variability exist are areas that warrant greater attention from researchers, policy makers, clinicians and patients. There is also a need to better understand how individuals may interact with CIH websites, and to develop tools to assist people to interpret the CIH-related information that they encounter.

The User Knows What to Call It: Incorporating Patient Voice Through User-Contributed Tags on a Participatory Platform About Health Management

BACKGROUND

Body listening, described as the act of paying attention to the body's signals and cues, can be an important component of long-term health management.

OBJECTIVE

The aim of this study was to introduce and evaluate the Body Listening Project, an innovative effort to engage the public in the creation of a public resource-to leverage collective wisdom in the health domain. This project involved a website where people could contribute their experiences of and dialogue with others concerning body listening and self-management. This article presents an analysis of the tags contributed, with a focus on the value of these tags for knowledge organization and incorporation into consumer-friendly health information retrieval systems.

METHODS

First, we performed content analysis of the tags contributed, identifying a set of categories and refining the relational structure of the categories to develop a preliminary classification scheme, the Body Listening and Self-Management Taxonomy. Second, we compared the concepts in the Body Listening and Self-Management Taxonomy with concepts that were automatically identified from an extant health knowledge resource, the Unified Medical Language System (UMLS), to better characterize the information that participants contributed. Third, we employed visualization techniques to explore the concept space of the tags. A correlation matrix, based on the extent to which categories tended to be assigned to the same tags, was used to study the interrelatedness of the taxonomy categories. Then a network visualization was used to investigate structural relationships among the categories in the taxonomy.

RESULTS

First, we proposed a taxonomy called the Body Listening and Self-Management Taxonomy, with four meta-level categories: (1) health management strategies, (2) concepts and states, (3) influencers, and (4) health-related information behavior. This taxonomy could inform future efforts to organize knowledge and content of this subject matter. Second, we compared the categories from this taxonomy with the UMLS concepts that were identified. Though the UMLS offers benefits such as speed and breadth of coverage, the Body Listening and Self-Management Taxonomy is more consumer-centric. Third, the correlation matrix and network visualization demonstrated that there are natural areas of ambiguity and semantic relatedness in the meanings of the concepts in the Body Listening and Self-Management Taxonomy. Use of these visualizations can be helpful in practice settings, to help library and information science practitioners understand and resolve potential challenges in classification; in research, to characterize the structure of the conceptual space of health management; and in the development of consumer-centric health information retrieval systems.

CONCLUSIONS

A participatory platform can be employed to collect data concerning patient experiences of health management, which can in turn be used to develop new health knowledge resources or augment existing ones, as well as be incorporated into consumer-centric health information systems.

A constant conversation: tuning into and harmonizing the needs and priorities of the body and mind

Purpose: Individuals rely upon many types of information to manage an illness, including information provided by their own bodies. This study investigated how people tune into and manage the flow of information from their bodies to manage their health. Method: We developed a platform for participants to share and collaboratively reflect on how they engaged in this dialogic process, in which participants contributed to a discussion on topics relating to body listening and body awareness. Though the study was open to anyone interested in or wanting to contribute to knowledge on “body listening,” the social media recruitment focused on chronic conditions requiring self-care and having overlapping symptomatology, with chronic pain as the primary characteristic. A qualitative analysis method based on grounded theory was used to analyse the data. Results: Six main themes emerged: learning the language, recognizing and heeding limits, experiencing emotional fatigue and despair, regulating the channel, moving from conflict to communication, and settling into an uneasy acceptance. Conclusion: The monitoring and filtering of information from one’s body, and the appeasement of conflicting demands and voices, is difficult work. Knowledge of this process can be used in patient education and in the development of tools to support body listening.

Classifying Chinese Questions Related to Health Care Posted by Consumers Via the Internet

Background

In question answering (QA) system development, question classification is crucial for identifying information needs and improving the accuracy of returned answers. Although the questions are domain-specific, they are asked by non-professionals, making the question classification task more challenging.

Objective

This study aimed to classify health care–related questions posted by the general public (Chinese speakers) on the Internet.

Methods

A topic-based classification schema for health-related questions was built by manually annotating randomly selected questions. The Kappa statistic was used to measure the interrater reliability of multiple annotation results. Using the above corpus, we developed a machine-learning method to automatically classify these questions into one of the following six classes: Condition Management, Healthy Lifestyle, Diagnosis, Health Provider Choice, Treatment, and Epidemiology.

Results

The consumer health question schema was developed with a four-hierarchical-level of specificity, comprising 48 quaternary categories and 35 annotation rules. The 2000 sample questions were coded with 2000 major codes and 607 minor codes. Using natural language processing techniques, we expressed the Chinese questions as a set of lexical, grammatical, and semantic features. Furthermore, the effective features were selected to improve the question classification performance. From the 6-category classification results, we achieved an average precision of 91.41%, recall of 89.62%, and F₁ score of 90.24%.

Conclusions

In this study, we developed an automatic method to classify questions related to Chinese health care posted by the general public. It enables Artificial Intelligence (AI) agents to understand Internet users’ information needs on health care.
