RESUMO

OBJECTIVES: While state-based models of health-related quality of life (HRQL) are well-established in providing clinically relevant descriptions of HRQL status, they do not provide information on how to maintain or improve HRQL. The EvalUation of goal-diRected activities to prOmote well-beIng and heAlth (EUROIA), rooted in a novel process-based model of HRQL, measures goal-directed activities that are self-reported to promote HRQL as part of an individual's process of adapting to dynamic changes in health status. Our objectives were to condense and summarize the psychometric properties of the EUROIA by (i) defining and confirming its factor structure, (ii) evaluating its construct validity, and (iii) examining its internal consistency. METHODS: Principal component analysis was performed on the 18-item EUROIA to explore the underlying factor structure and condense the scale. Confirmatory factor analysis was conducted on the revised 14-item, 4-factor structure EUROIA instrument to evaluate the model fit. Data was obtained from adult participants with a diagnosis of chronic heart failure or advanced chronic kidney disease from 3 hospitals in Toronto, Canada. RESULTS: The revised 14-item EUROIA demonstrated 4 dimensions-Social Affiliation, fulfillment of Social Roles and Responsibilities, Self-Affirmation, and Eudaimonic Well-being-with a Cronbach's alpha of 0.83, representing good internal consistency. Our confirmatory factor analysis final model achieved good overall model fit: (χ2 / df = 1.80; Tucker-Lewis index = 0.90; comparative fit index = 0.93; standardized root-mean-square residual = 0.06; root-mean-square error of approximation = 0.06). All items exhibited a factor loading greater than λ > 0.4 and p < 0.001. CONCLUSION: The EUROIA holds clinical potential in its ability to provide informed feedback to patients on how they might maintain or modify their use of goal-directed activities to maintain and optimize perceived well-being.

RESUMO

BACKGROUND: Individual appraisals of personal well-being consider a spectrum of constructs including the reflections on the degree to which one's life is ultimately secure, meaningful, or valued in the context of dynamic changes in their bio-psycho-social environments. Standardized questionnaires for well-being evaluate an ideal state of health which is operationally defined by abstract constructs. Patient reports describe well-being as a more dynamic construct that relates to how they adapt to successive changes in their life situations. While response shift theory addresses this dynamic nature, little is known about how personal well-being is pursued as personal aspirations evolve. In this study, we identify regularly practiced goal-directed activities reported to contribute to the pursuit of personal well-being. We then propose a taxonomy of these reported activities to inform a process-based model for well-being. METHODS: Purposive sampling was conducted with individuals, 30 to 60 years of age, with diverse ethnicities reflecting the Singaporean population. Individual semi-structured interviews were administered with the primary question: "What are the things or activities you have done in the last two weeks that made you feel like you had a good day?" Probes explored the personally salient meaning of each activity. A thematic approach was used for data analysis followed by a framework analysis to categorize the activities into major themes. RESULTS: We interviewed 40 individuals comprised of 60% female participants. Thematic analysis identified eight types of goal-directed activities, which were categorized under three major themes: (i) Self-Affirming Care through individual self-care and maintaining interpersonal relationships, (ii) Achievement-Focused Tasks as indicated by work-related accomplishments and developing a skill or hobby, (iii) Affiliative Growth and Support as reflected through religious practices and community services. Planned physical activity contributed to self-affirming care and achievement-focused tasks. Social affirming roles were associated with both achievement-focused tasks and affiliative growth and support. CONCLUSIONS: In the dimensions of goal-directed activities identified, there is close alignment between Self-Affirming Care and attachment theory; Achievement-Focused Tasks and self-determination theory; and Affiliative Growth and Support and social mattering. These findings can contribute to a comprehensive process-based model of well-being which is more closely aligned to patient-report appraisals of personal well-being.

RESUMO

This paper proposes that resources from philosophy as a way of life (PWL), in particular the prescription of targeted 'spiritual exercises' (Hadot) can be used in palliative counselling, addressing Alexandrova's critique that philosophy as 'big picture' theories alone are insufficient. Part I shows how the disciplines of philosophy and medicine for a long time intersected, in particular in competing prescriptive notions of 'regimen' or 'way of life' (diaitês) in the ancient world, in which philosophy was considered widely as PWL. Part II applies PWL work on the ancient philosophical spiritual exercises to contemporary clinical settings. We show how six ancient spiritual exercises respond to patients' needs as persons, whose quality of life is importantly shaped by their beliefs and sense-making, as they face profound existential or spiritual challenges, as well as forms of physical disability and diminished capabilities which they may never have previously countenanced.

RESUMO

Background: Task force statements support the use of cognitive behavioral therapy (CBT) and motivational interviewing (MI) to promote self-care in chronic heart failure (CHF) patients. Digital counseling interventions have the potential to complement conventional programs. However, therapeutic components of digital programs associated with improved outcomes are not clearly established. Objective: Identify therapeutic components of the Canadian e-Platform to Promote Behavioral Self-Management in Chronic Heart Failure (CHF-CePPORT) protocol that were associated with improved health-related quality of life (HRQL). Materials and methods: Ordinal logistic regression was used to identify therapeutic components of the CHF-CePPORT protocol. The primary outcome was the 12-month Kansas City Cardiomyopathy Questionnaire Overall Summary (KCCQ-OS) tertile. Logistic regressions determined the association between 12-month KCCQ-OS tertile, using logon hours for key segments of the protocol, modality of content delivery, and clinical themes. Results: A total of 117 patients were enrolled in the e-Counseling arm of the CHF-CePPORT trial. Median age was 60 years (IQR 52-69). Total logon hours in the initial 4-month segment of CHF-CePPORT (Sessions 1-16) was associated with increased 12-month KCCQ-OS tertile (Odds Ratio, OR = 1.31, 95% CI, 1.1-1.5, P = 0.001). Within sessions 1-16, improved KCCQ-OS was associated with logon hours for self-assessment tools/trackers (OR = 1.49, 95% CI, 1.1-2.0, P = 0.007), and videos (OR = 1.57, 95% CI, 1.03-2.4, P = 0.04), but not for CHF information pages. Conclusion: This study highlights the importance of using evidence-based guidelines from CBT and MI as core components of digital counseling, delivered through videos and interactive tools/trackers, to improve HRQL with CHF.

RESUMO

BACKGROUND: Chronic conditions are characterized by their long duration (≥1 year), need for ongoing medical attention, and limitations in activities of daily living. These can often co-occur with depression and anxiety as common and detrimental comorbidities among the growing population living with chronic conditions. Digital health interventions (DHIs) hold promise in overcoming barriers to accessing mental health support for these individuals; however, the design and implementation of DHIs for depression and anxiety in people with chronic conditions are yet to be explored. OBJECTIVE: This study aimed to explore what is known in the literature regarding DHIs for the prevention, detection, or treatment of depression and anxiety among people with chronic conditions. METHODS: A scoping review of the literature was conducted using the Arksey and O'Malley framework. Searches of the literature published in 5 databases between 1990 and 2019 were conducted in April 2019 and updated in March 2021. To be included, studies must have described a DHI tested with, or designed for, the prevention, detection, or treatment of depression or anxiety in people with common chronic conditions (arthritis, asthma, diabetes mellitus, heart disease, chronic obstructive pulmonary disease, cancer, stroke, and Alzheimer disease or dementia). Studies were independently screened by 2 reviewers against the inclusion and exclusion criteria. Both quantitative and qualitative data were extracted, charted, and synthesized to provide a descriptive summary of the trends and considerations for future research. RESULTS: Database searches yielded 11,422 articles across the initial and updated searches, 53 (0.46%) of which were included in this review. DHIs predominantly sought to provide treatment (44/53, 83%), followed by detection (5/53, 9%) and prevention (4/53, 8%). Most DHIs were focused on depression (36/53, 68%), guided (32/53, 60%), tailored to chronic physical conditions (19/53, 36%), and delivered through web-based platforms (20/53, 38%). Only 2 studies described the implementation of a DHI. CONCLUSIONS: As a growing research area, DHIs offer the potential to address the gap in care for depression and anxiety among people with chronic conditions; however, their implementation in standard care is scarce. Although stepped care has been identified as a promising model to implement efficacious DHIs, few studies have investigated the use of DHIs for depression and anxiety among chronic conditions using such models. In developing stepped care, we outlined DHI tailoring, guidance, and intensity as key considerations that require further research.

RESUMO

Background: Self-management has shown to improve the quality of life in patients with chronic kidney disease (CKD). Readily accessible self-management tools are essential in promoting adherence to self-care behaviors. In recognizing that digital health facilitates efficient access to self-management programs, we developed a digital counseling program, ODYSSEE Kidney Health, to promote self-care behaviors while supporting health-related quality of life. Objective: To present the design and development of ODYSSEE Kidney Health for digital counseling for patients with CKD. Design: The study involved an iterative design process based on user-centered design principles to develop the digital counseling program, ODYSSEE Kidney Health. Setting: A sample of 10 to 15 participants were purposively sampled from nephrology clinics at the University Health Network, Toronto, Canada. Methods: Participants underwent 2 phases in the development process. In each phase, participants were presented with a component of the program, asked to perform goal-oriented tasks, and participate in the "think-aloud" process. Semi-structured interviews followed the first phase to identify feedback about the overall program. Thematic analysis of the interviews identified themes from the usability testing. Descriptive statistics were used to summarize patient demographic data. Results: We enrolled 11 participants (n = 7 males, n = 4 females, ages 30-82). The main themes generated anchored on (1) impact on nephrology care, (2) technical features, and (3) CKD content. Overall, participants reported positive satisfaction toward the navigation, layout, and content of the program. They cited the value of the program in their daily CKD care. Limitations: Study limitations included using a single center to recruit participants, most of the participants having prior technology use, and using one module as a representative of the entire digital platform. Conclusion: The acceptability of a digital counseling program for patients with CKD relies on taking the patients' perspective using a user-centered design process. It is vital in ensuring adoption and adherence to self-management interventions aimed at sustaining behavioral change.


Contexte: L'autogestion s'est avérée efficace pour améliorer la qualité de vie des patients atteints d'insuffisance rénale chronique (IRC). Des outils d'autogestion facilement accessibles sont essentiels pour favoriser l'adhésion aux comportements d'autogestion. Conscients que la santé numérique facilite l'accès efficace aux programmes d'autogestion, nous avons mis au point un programme de consultation numérique, ODYSSEE Kidney Health, afin de promouvoir les comportements d'autogestion tout en soutenant la qualité de vie liée à la santé. Objectif: Présenter la conception et le développement du programme de consultation numérique ODYSSEE Kidney Health, destiné aux patients atteints d'IRC. Conception: L'étude a impliqué un processus de conception itératif fondé sur des principes de conception axés sur l'utilisateur pour développer le programme de consultation numérique, ODYSSEE Kidney Health. Participants: Un échantillon de 10 à 15 participants choisis à dessein dans des cliniques de néphrologie du University Health Network de Toronto (Canada). Méthodologie: Les participants ont pris part à deux phases du processus de développement. À chaque phase, une composante du programme a été présentée aux participants et ceux-ci ont été invités à effectuer des tâches axées sur les objectifs et à participer à un processus de « réflexion à voix haute ¼. Des entretiens semi-structurés ont suivi la première phase pour fournir de la rétroaction sur le programme dans son ensemble. L'analyse thématique des entretiens a permis de dégager les thèmes des tests d'utilisabilité. Des statistiques descriptives ont servi à présenter les données démographiques des patients. Résultats: Nous avons inclus 11 participants (7 hommes, 4 femmes; de 30 à 82 ans). Les principaux thèmes générés sont ancrés sur: 1) l'impact sur les soins de néphrologie, 2) les caractéristiques techniques et 3) le contenu sur l'IRC. Dans l'ensemble, les participants étaient satisfaits de leur expérience de navigation, de la disposition des contenus et du contenu du programme. Ils ont mentionné la valeur du programme dans leurs soins quotidiens d'IRC. Limites: Un seul centre a été utilisé pour recruter des participants, la majorité des participants avait déjà utilisé la technologie et un seul module a été utilisé pour représenter l'ensemble de la plateforme numérique. Conclusion: L'acceptabilité d'un programme de consultation numérique destiné aux patients atteints d'IRC repose sur la prise en compte du point de vue des patients par le biais d'un processus de conception axé sur l'utilisateur. Ceci est essentiel pour garantir l'adoption et l'adhésion aux interventions d'autogestion visant à pérenniser les changements de comportement.

RESUMO

Background: Music performance anxiety is a common experience among elite and professional musicians and impedes performers from achieving flow state, or a state of focused, sustained engagement that promotes optimal performance. Objective: The aim of this study was to use heart rate variability (HRV) to determine the psychophysiological underpinnings of optimal music performance. Methods: We assessed HRV to study how autonomic-cardiac modulation was associated with flow during piano performance. Twenty-two pianists (15-22 years) with at least a Grade 8 Royal Conservatory of Music certification prepared two standardized pieces and a self-selected piece. Performer heart rate data were measured with a Polar 800 watch in 5-min periods immediately before performances, during performances and post-performance. HRV was employed to assess autonomic modulation of cardiac intervals. HRV indices of sympathetic and parasympathetic modulation of the heart were analyzed in 2.5-min segments to monitor short-term autonomic adjustments using the Kubios HRV Software. Flow state was measured using the 36-item Flow State Scale (FSS). Relationships were analyzed using zero-order correlations and multiple linear regressions. Results: Our sample consisted of 22 RCM Grade 8 certified pianists. Participants achieved the highest level of flow during performance of the Bach piece. Decreased HRV was observed during performance, as indicated by a significant drop in total power. Flow state was positively associated with High Frequency (HF) power during the pre-performance phase, and inversely associated with Low Frequency (LF) power during performance. Conclusion: Inverse association of flow with LF-HRV during performance affirms the importance of vagal-HR modulation for achievement of flow state. Increased HF-HRV and reduced LF-HRV immediately prior to performance suggests that flow state may be shaped as much by physiological preparation during pre-performance as it is by physiologic responses during performance. Further research is required to validate the correlation between autonomic modulation of the heart and flow state. Evidence of this correlation between autonomic modulation of the heart and achievement of flow state may pave the way for further research on enhancing musical performance and targeting MPA through HRV-based interventions.

RESUMO

INTRODUCTION: Heart failure (HF) symptoms improve through self-care, for which adherence remains low among patients despite the provision of education for these behaviours by clinical teams. Open Access Digital Community Promoting Self-Care, Peer Support and Health Literacy (ODYSSEE-vCHAT) combines automated digital counselling with social network support to improve mortality and morbidity, engagement with self-care materials, and health-related quality of life. METHODS AND ANALYSIS: Use of ODYSSEE-vCHAT via Internet-connected personal computer by 162 HF patients will be compared with a control condition over 22 months. The primary outcome is a composite index score of all-cause mortality, all-cause emergency department visits, and HF-related hospitalisation at trial completion. Secondary outcomes include individual components of the composite index, engagement with self-care materials, and patient-reported measures of physical and psychosocial well-being, disease management, health literacy, and substance use. Patients are recruited from tertiary care hospitals in Toronto, Canada and randomised on a 1:1 ratio to both arms of the trial. Online assessments occur at baseline (t=0), months 4, 8 and 12, and trial completion. Ordinal logistic regression analyses and generalised linear models will evaluate primary and secondary outcomes. ETHICS AND DISSEMINATION: The trial has been approved by the research ethics boards at the University Health Network (20-5960), Sunnybrook Hospital (5117), and Mount Sinai Hospital (21-022-E). Informed consent of eligible patients occurs in person or online. Findings will be shared with key stakeholders and the public. Results will allow for the preparation of a Canada-wide phase III trial to evaluate the efficacy of ODYSSEE-vCHAT in improving clinical outcomes and raising the standard of outpatient care. TRIAL REGISTRATION NUMBER: NCT04966104.

RESUMO

BACKGROUND: International task force statements advocate telehealth programs to promote health-related quality of life for patients with chronic heart failure (CHF). To that end, we evaluated the efficacy and usability of an automated e-counseling program. METHODS: This Canadian multi-site double-blind randomized trial assessed whether usual care plus either internet-based e-counseling (motivational and cognitive-behavioral tools for CHF self-care) or e-based conventional CHF self-care education (e-UC) improved 12-month Kansas City Cardiomyopathy Questionnaire Overall Summary (KCCQ-OS). Secondary outcomes included program engagement (total logon weeks, logons, and logon hours), total CHF self-care behaviors, diet (fruit and vegetable servings), 6-minute walk test, and 4-day step count. The association between program engagement and health-related quality of life was assessed using KCCQ-OS tertiles. RESULTS: We enrolled 231 patients, median age =59.5 years, 22% female, and elevated median KCCQ-OS=83.0 (interquartile range, 68-93). KCCQ-OS increase ≥5 points was not more prevalent for e-counseling, n=29 (29.6%) versus e-UC, n=32 (34.0%), P=0.51. E-Counseling versus e-UC increased total logon weeks (P=0.02), logon hours (P=0.001), and logons (P<0.001). Only e-counseling showed a positive association between 12-month KCCQ-OS tertile and logon weeks (P=0.04) and logon hours (P=0.004). E-Counseling increased CHF self-care behavior and diet but not 6-minute walk test or 4-day step count. CONCLUSIONS: The primary KCCQ-OS end point was negative for this trial. Only e-counseling showed a positive association between program engagement and 12-month KCCQ-OS tertile, and it improved CHF self-care behavior and diet.

RESUMO

BACKGROUND: Persons identifying as Black, Chinese, or South Asian make up the largest minority groups in Canada. Individuals with chronic heart failure (CHF) from these groups experience a greater rate of re-hospitalization and poorer quality of life. Although experts agree that culture can shape the experience of CHF, little is known about how patients from these minority populations define a good quality of life with CHF and what barriers they experience when carrying out self-care behaviours. The aim of this qualitative study was to examine cultural and gender-based influences on quality of life in patients with CHF. METHODS: Purposive sampling included 30 patients (67% male), 18 to 75 years of age, who self-identified as Black (n = 8), Chinese (n = 9), or South Asian (n = 6). Caucasians (n = 7) were included as a comparison group. Semi-structured interviews (see the online appendix), lasting approximately 60 min, were conducted, which focused on personal understanding of CHF and living with the disease, including impact on lifestyle and quality of life. An inductive qualitative approach with thematic content analysis was used to develop key insights into individual experience of CHF, as well as cultural and gender-based influences on self-care and quality of life. Descriptive statistics were generated from questionnaire responses. RESULTS: Five key themes emerged from the narrative analysis of participant interviews: (i) CHF as an emergent reality, (ii) quality of life and disruption of lifecourse milestones, (iii) the challenge to accept CHF and re-evaluation of quality of life; (iv) impact on social activities essential to quality of life, and (v) life with CHF as a commitment to culturally tailored self-care. Participants described the unique impact of CHF on their quality of life, including life trajectory milestones such as dating, parenting, and retirement planning, as well as the importance of accepting their diagnosis, and the reframing goals for living well with heart failure. Positive and negative impacts on social relationships were noted, including sexual intimacy and interactions with spouses, other family members, and co-workers. CONCLUSIONS: Study findings highlight important lifespan, cultural, and gender considerations that can inform the improvement of patient care and quality of life for patients and their families.

RESUMO

OBJECTIVES: To evaluate the compliance with prospective registration and inclusion of the trial registration number (TRN) in published randomised controlled trials (RCTs), and to analyse the rationale behind, and detect selective registration bias in, retrospective trial registration. DESIGN: Cross sectional analysis. DATA SOURCES: PubMed, the 17 World Health Organization's trial registries, University of Toronto library, International Committee of Medical Journal Editors (ICMJE) list of member journals, and the InCites Journal Citation Reports. STUDY SELECTION CRITERIA: RCTs registered in any WHO trial registry and published in any PubMed indexed journal in 2018. RESULTS: This study included 10 500 manuscripts published in 2105 journals. Overall, 71.2% (7473/10500) reported the TRN and 41.7% (3013/7218) complied with prospective trial registration. The univariable and multivariable analyses reported significant relations (P<0.05) between reporting the TRN and the impact factor and ICMJE membership of the publishing journal. A significant relation (P<0.05) was also observed between prospective trial registration and the registry, region, condition, funding, trial size, interval between paper registration and submission dates, impact factor, and ICMJE membership of the publishing journal. A manuscript published in an ICMJE member journal was 5.8 times more likely to include the TRN (odds ratio 5.8, 95% confidence interval 4.0 to 8.2), and a published trial was 1.8 times more likely to be registered prospectively (1.8, 1.5 to 2.2) when published in an ICMJE member journal compared with other journals. This study detected a new form of bias, selective registration bias, with a higher proportion (85.2% (616/723)) of trials registered retrospectively within a year of submission for publication. Higher rates of retrospective registrations were observed within the first three to eight weeks after enrolment of study participants. Within the 286 RCTs registered retrospectively and published in an ICMJE member journal, only 2.8% (8/286) of the authors included a statement justifying the delayed registration. Reasons included lack of awareness, error of omission, and the registration process taking longer than anticipated. CONCLUSIONS: This study found a high compliance in reporting of the TRN for trial papers published in ICMJE member journals, but prospective trial registration was low.

RESUMO

BACKGROUND: Behavioural counselling via internet- or mobile-based digital platforms is recommended for hypertension; however, outcome heterogeneity is problematic in trials of this digital intervention. Our objective was to assess how therapeutic outcome was optimized in digital trials for hypertension, according to key features of the intervention design and protocol. METHODS: We identified randomized controlled digital trials for systolic blood pressure (SBP) reduction in taskforce guideline and policy statements, systematic reviews, and meta-analyses published since 2010, by searching the EMBASE, Cochrane Library, psycINFO, and PubMed databases. This search was updated to January 2019. Trials included patients with elevated cardiovascular risk or cardiovascular disease. We classified digital trials by the number of components of the intervention, and whether the protocol was organized by an explicit model of behavioural change or counselling. The influence of these features was evaluated for treatment efficacy and heterogeneity of SBP outcomes. RESULTS: Seventeen trials met inclusion criteria: pooled n = 5780, 33% female, 93% taking antihypertensive medications. SBP reduction was -7.3 mm Hg for digital counselling (95% confidence interval: -7.0 to -7.5) vs -3.6 mm Hg for control (95% confidence interval: -3.4 to -3.9), P < 0.0001, with high-moderate heterogeneity (I2 = 67%). Trials with multiple behavioural intervention components and an organized theoretical framework of behaviour change or counselling demonstrated optimal SBP reduction with low-moderate heterogeneity (I2 = 49%). CONCLUSIONS: Digital health interventions optimize the efficacy of medical therapy for SBP reduction. There is opportunity to promote a disruptive change in clinical science that accompanies technological developments in digital health promotion.

RESUMO

OBJECTIVE: 1) Evaluate the efficacy of e-Counseling vs. Control to promote lifestyle behaviors at 4 and 12-month follow-ups, 2) examine whether these behaviors changes were associated with lower blood pressure (BP), and Framingham Risk Index (FRI) at 12-month. METHODS: Hypertensive patients (n = 264) were randomized to the e-Counseling or the Control group. Primary trial outcome was BP and secondary outcomes included exercise and diet behaviors. This study presented the results of secondary outcomes. Linear mixed models evaluated treatment effects at 4 and 12-month. Treatment-by-sex exploratory analyses were conducted if no main treatment effect was observed. RESULTS: Daily steps significantly improved in e-Counseling vs. Controls at 12-month. Urinary sodium at 12-month did not significantly differ between the groups, but treatment-by-sex analysis showed that e-Counseling females lowered urinary sodium relative to Controls at 12 months. Improvements in steps and dietary sodium were significantly associated with improvements in BP and FRI at 12-month. CONCLUSION: This hypertension e-Counseling protocol can promote long-term lifestyle behavior changes. Adherence to the lifestyle behavior change was associated with BP and FRI reduction at 12-month. PRACTICE IMPLICATIONS: The hypertension e-counseling protocol has the potential to improve hypertension care and intervention reach.

RESUMO

BACKGROUND: Clinical trials are key to advancing evidence-based medical research. The medical research literature has identified the impact of publication bias in clinical trials. Selective publication for positive outcomes or nonpublication of negative results could misdirect subsequent research and result in literature reviews leaning toward positive outcomes. Digital health trials face specific challenges, including a high attrition rate, usability issues, and insufficient formative research. These challenges may contribute to nonpublication of the trial results. To our knowledge, no study has thus far reported the nonpublication rates of digital health trials. OBJECTIVE: The primary research objective was to evaluate the nonpublication rate of digital health randomized clinical trials registered in ClinicalTrials.gov. Our secondary research objective was to determine whether industry funding contributes to nonpublication of digital health trials. METHODS: To identify digital health trials, a list of 47 search terms was developed through an iterative process and applied to the "Title," "Interventions," and "Outcome Measures" fields of registered trials with completion dates between April 1, 2010, and April 1, 2013. The search was based on the full dataset exported from the ClinlicalTrials.gov database, with 265,657 trials entries downloaded on February 10, 2018, to allow publication of studies within 5 years of trial completion. We identified publications related to the results of the trials through a comprehensive approach that included an automated and manual publication-identification process. RESULTS: In total, 6717 articles matched the a priori search terms, of which 803 trials matched our latest completion date criteria. After screening, 556 trials were included in this study. We found that 150 (27%) of all included trials remained unpublished 5 years after their completion date. In bivariate analyses, we observed statistically significant differences in trial characteristics between published and unpublished trials in terms of the intervention target condition, country, trial size, trial phases, recruitment, and prospective trial registration. In multivariate analyses, differences in trial characteristics between published and unpublished trials remained statistically significant for the intervention target condition, country, trial size, trial phases, and recruitment; the odds of publication for non-US-based trials were significant, and these trials were 3.3 (95% CI 1.845-5.964) times more likely to be published than US-based trials. We observed a trend of 1.5 times higher nonpublication rates for industry-funded trials. However, the trend was not statistically significant. CONCLUSIONS: In the domain of digital health, 27% of registered clinical trials results are unpublished, which is lower than nonpublication rates in other fields. There are substantial differences in nonpublication rates between trials funded by industry and nonindustry sponsors. Further research is required to define the determinants and reasons for nonpublication and, more importantly, to articulate the impact and risk of publication bias in the field of digital health trials.

RESUMO

BACKGROUND: The efficacy of internet-based interventions to improve hypertension management is not established. We evaluated the therapeutic benefit of e-counseling by adapting best evidence guidelines for behavioral counseling. METHODS AND RESULTS: This multicenter double-blind randomized controlled trial included assessments at baseline, 4 months, and 12 months. Participants were 35 to 74 years of age and diagnosed with hypertension: systolic/diastolic blood pressure (BP) 130 to 180/85 to 110 mm Hg. BP was assessed by automated office measurement. E-Counseling used multimedia and interactive tools to increase motivation and skill for self-care (exercise, diet, medication adherence, and smoking cessation). Control used self-care education. Frequency of contact by our e-platform was equal for both trial arms. Primary end points were change at 4 and 12 months in systolic BP, diastolic BP, pulse pressure, total lipoprotein cholesterol, low-density lipoprotein cholesterol, total lipoprotein cholesterol/high-density lipoprotein cholesterol ratio, non-high-density lipoprotein cholesterol, and Framingham 10-year cardiovascular risk index. Intention-to-treat analysis used generalized linear models adjusted for baseline measures, sex, and medications. Among 264 participants, mean age was 57.6 years (SE, 0.6), 58% were women, with 83% on antihypertensive medications. At 12 months, e-counseling versus control evoked greater reduction in systolic BP (-10.1 mm Hg [95% confidence interval (CI), -12.5, -7.6] versus -6.0 mm Hg [95% CI, -8.5, -3.5]; P=0.02); pulse pressure (-5.2 mm Hg [95% CI, -6.9, -3.5] versus -2.7 mm Hg [95% CI, -4.5, -0.9]; P=0.04), and Framingham risk index (-1.9% [95% CI, -3.3, -0.5] versus -0.02% [95% CI, -1.2, 1.7]; P=0.02), respectively. Among males in e-counseling versus control, 12-month end points included lower diastolic BP (P=0.01), non-high-density lipoprotein cholesterol (P=0.04), total lipoprotein cholesterol (P=0.03), and a trend for total lipoprotein cholesterol/high-density lipoprotein cholesterol ratio (P=0.07). CONCLUSIONS: To our knowledge, this is the first double-blind randomized trial of e-counseling for hypertension. Added benefit for medical therapy was achieved by combining available technology with a clinically organized protocol of motivational and cognitive-behavioral counseling.

RESUMO

BACKGROUND: Practice guidelines advocate combining pharmacotherapy with lifestyle counseling for patients with hypertension. To allow for appropriate tailoring of interventions to meet individual patient needs, a comprehensive understanding of baseline patient characteristics is essential. However, few studies have empirically assessed behavioral profiles of hypertensive patients in Web-based lifestyle counseling programs. OBJECTIVE: The objectives of this study were to (1) specify baseline psychobehavioral profiles of patients with hypertension who were enrolled in a Web-based lifestyle counseling trial, and (2) examine mean differences among the identified profile groups in demographics, psychological distress, self-reported self-care behaviors, physiological outcomes, and program engagement to determine prognostic implications. METHODS: Participants (N=264; mean age 57.5 years; 154/264, 58.3% female; 193/264, 73.1% white) were recruited into a longitudinal, double-blind, randomized controlled trial, designed to evaluate an online lifestyle intervention for hypertensive patients. A series of latent profile analyses identified psychobehavioral profiles, indicated by baseline measures of mood, motivation, and health behaviors. Mean differences between profile groups were then explored. RESULTS: A 2-class solution provided the best model fit (the Bayesian information criterion (BIC) is 10,133.11; sample-size adjusted BIC is 10,006.54; Lo-Mendell-Rubin likelihood ratio test is 65.56, P=.001). The 2 profile groups were (1) adaptive adjustment, marked by low distress, high motivation, and somewhat satisfactory engagement in health behaviors and (2) affectively distressed, marked by clinically significant distress. At baseline, on average, affectively distressed patients had lower income, higher body mass index, and endorsed higher stress compared with their adaptive adjustment counterparts. At 12-months post intervention, treatment effects were sustained for systolic blood pressure and Framingham risk index in the adaptive adjustment group, and those in the adaptive adjustment group were 2.4 times more likely to complete the 12-month intervention study, compared with their affectively distressed counterparts. CONCLUSIONS: Interventions for patients who are adaptively adjusted may differ in focus from those designed for the affectively distressed patients. As such, this study underscores the importance of identifying psychobehavioral profiles, as they allow for evidence-based tailoring of lifestyle counseling programs for patients with hypertension.

RESUMO

BACKGROUND: North American adults with congenital heart disease (CHD) are known to be at elevated risk of mood and anxiety disorders. This was the first trial of a group psychosocial intervention targeting this patient population. METHODS: Within this feasibility study, we conducted a 2-arm pilot randomized controlled trial (RCT) in which patients were randomized to Usual Care or an 8-session group psychosocial intervention (Adult Congenital Heart Disease-Coping and Resilience [ACHD-CARE]). Here, we report feasibility outcomes in accordance with published recommendations: (1) process, (2) resources, (3) management, (4) acceptability of the intervention, and (5) scientific outcomes (for which the primary outcome measures were anxiety and depression symptoms). RESULTS: Forty-two patients were randomized in the pilot RCT. The study was executable within a realistic timeline and revealed no significant human and data-management problems. The intervention was determined to be acceptable and highly valued by participants who participated in the ACHD-CARE program. The main challenges were practical barriers (eg, transportation, scheduling group sessions in-person given competing schedules) and retention. With regard to scientific outcomes, there were no adverse outcomes, and treatment fidelity was confirmed. Although not powered to test efficacy, there was a medium effect size (in favour of the intervention group) for depression symptoms. CONCLUSIONS: We determined it would be feasible to conduct a full-scale trial of a psychosocial intervention targeting adults with CHD, although with modifications to address practical barriers to participation. Should this intervention prove effective, a manualized intervention could be made be available.
