A cultural and gender-based approach to understanding patient adjustment to chronic heart failure.

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.

Randomized Controlled Trial of E-Counseling for Hypertension: REACH.

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.

A Moderated e-Forum for Adults With Cardiovascular Disease: Usability Study.

BACKGROUND: Self-care behaviors are commonly prescribed to manage both cardiovascular disease and hypertension to reduce modifiable risk factors and improve quality of life. Nevertheless, long-term adherence to self-care recommendations for cardiac patients has been problematic. In cardiac patients, moderated online forums have been found to be particularly useful in supporting maintenance of heart-healthy diet and fewer hospital visits. As such, we developed the e-Forum, a Web-based moderated forum designed to promote continued user engagement and long-term self-care adherence. OBJECTIVE: The objective of this study was to assess the usability of the user interface for the newly designed e-Forum. In addition to overall user satisfaction, we obtained feedback from our target users on the key features of this newly developed interface. METHODS: An iterative design tested the usability of the e-Forum. On the basis of the user feedback, adjustments were made to the design of our e-Forum, and these changes were then tested in the succeeding group. Participants were recruited from the Heart Function Clinic at the Peter Munk Cardiac Center, University Health Network. After consenting to participate in our study, patients were asked to complete a set of goal-oriented tasks and a feedback interview for the e-Forum. A content analysis of the transcripts from the set of goal-oriented tasks and feedback interviews identified several themes, including general feedback and comments regarding 3 key areas of the e-Forum: layout, navigation, and content. RESULTS: Overall, 13 cardiac patients (aged 32-81 years) participated in 3 rounds of testing. Participants across all 3 rounds were highly satisfied with our e-Forum and indicated that they would find such a forum useful in managing their health. Expressions of overall satisfaction with the e-Forum and positive comments regarding layout increased between the initial and the final round. As improvements were made to the e-Forum based on participant feedback, potential barriers, negative comments related to the content, and the number of navigation errors decreased between rounds 1 and 3. CONCLUSIONS: We found evidence to support the usability of the user interface for our e-Forum. These results indicate that the e-Forum will likely be a successful tool to support an online community of cardiac patients in their efforts to sustain long-term lifestyle behavior change.

Usability Testing of an Internet-Based e-Counseling Platform for Adults With Chronic Heart Failure.

BACKGROUND: Chronic heart failure (CHF) is a major cause of hospitalization and mortality. In order to maintain heart function and quality of life, patients with CHF need to follow recommended self-care guidelines (ie, eating a heart healthy diet, exercising regularly, taking medications as prescribed, monitoring their symptoms, and living a smoke-free life). Yet, adherence to self-care is poor. We have developed an Internet-based e-Counseling platform, Canadian e-Platform to Promote Behavioral Self-Management in Chronic Heart Failure (CHF-CePPORT), that aims to improve self-care adherence and quality of life in people with CHF. Before assessing the efficacy of this e-platform in a multisite, double-blind, randomized controlled trial, we evaluated the usability of the prototype website. OBJECTIVE: The objective of the study was to assess the usability of the CHF-CePPORT e-Counseling platform in terms of navigation, content, and layout. METHODS: CHF patients were purposively sampled from the Heart Function Clinic at the Peter Munk Cardiac Center, University Health Network, to participate in this study. We asked the consented participants to perform specific tasks on the website. These tasks included watching self-help videos and reviewing content as directed. Their interactions with the website were captured using the "think aloud" protocol. After completing the tasks, research personnel conducted a semi-structured interview with each participant to assess their experience with the website. Content analysis of the transcripts from the "think aloud" sessions and the interviews was conducted to identify themes related to navigation, content, and layout of the website. Descriptive statistics were used to summarize the satisfaction data. RESULTS: A total of 7 men and women (ages 39-77) participated in 2 iterative rounds of testing. Overall, all participants were very satisfied with the content and layout of the website. They reported that the content was helpful to their management of CHF and that it reflected their experiences in coping with CHF. The layout was professional and friendly. The use of videos made the learning process entertaining. However, they experienced many navigation errors in the first round of testing. For example, some participants were not sure how to navigate across a series of Web pages. Based on the experiences that were reported in the first round, we made several changes to the navigation structure. This included using large navigation buttons to direct users to each section and providing tutorial videos to familiarize users with our website. We assessed whether these changes improved user navigation in the second round of testing. The major finding is that participants made fewer navigation errors and they did not identify any new problems. CONCLUSIONS: We found evidence to support the usability of our CHF-CePPORT e-Counseling platform. Our findings highlight the importance of a clear and easy-to-follow navigation structure on user experience.
