Clinical Trial Summary

Patients with Chronic Heart Failure diagnosed and conventional treated, but still symptomatic (i.e. breathlessness, fatigue) is invited.

Eligible patients are randomised to (1) care as usual (i.e. optimized medical treatment) or (2) care as usual (i.e. optimized medical treatment) in combination with an 8-week mindfulness-based educational and training program.

Specific research questions:

• How are self-reported symptoms of breathlessness, fatigue, difficult sleeping, anxiety and depression affected by a mindfulness-based educational and training program (MBI)?

• Does the implementation of an 8-week Mindfulness-based program have any impact on personal experiences of well-being and health?

• What effects does an 8-week MBI have on objective signs of importance for the progression of heart failure?

Description:

Effects of a Mindfulness-Based Intervention on Symptoms and Signs, Well-Being and Health in Patients with Chronic Heart Failure

Rationale: Despite progress in medical treatment, many patients with heart failure, still suffers from limiting symptoms with negative impact on their prognosis, wellbeing and health. Psychological distress, including anxiety and depression, is prevalent and difficult to treat in heart failure. Mindfulness-based interventions (MBIs), have shown beneficial effects on psychological and physiological symptoms, health and quality of life in other chronic conditions. The aims of the project were therefore to explore the feasibility and effects of MBI on symptoms and signs, well-being and health in patients diagnosed with chronic heart failure.

Hypothesis: was that outpatients with chronic heart failure would benefit from participating in an 8-week Mindfulness-based educational and training program (MBI) in addition to usual care (comprising standard health care and optimized medical treatment). With respect to (1) alleviate impact of symptoms (fatigue, breathlessness, impaired sleep, anxiety and depression), and (2) improve perceived wellbeing and health, and the sense of coherence (patient-reported outcomes), and (3) objective signs of importance for heart failure progression (heart rate, breathing rate, functional classification and capacity).

Study design: A prospective study, with a two-armed randomized and controlled designed, including two visits, was planned and initiated, integrated within the framework of a part-financed dissertation project. Complemented with qualitative research on participants' experiences of health, symptoms and the MBI.

Intervention: The intervention group received an 8-week MBI program in addition to treatment and care as usual (UC+MBI), while the control group received only treatment and care as usual (UC).

Data is collected in interviews and with clinical measurement of signs on site, and with validated patient-reported questionnaires, before and after 8-week intervention (UC+MBI) / Control (UC) period. Interviews were recorded and coded. Participants receive a minor physical examination with measurements of blood pressure, heart rate, breathing rate, weight and height, and assessment with a six-minute walk test. Participants is also provided with questionnaires to be answered at home, and send in to the University.

Nature and extend of the burden and risks: Due to the character of the MBI, with focused attention on thoughts, feelings and bodily sensations, emotional reactions may be a risk (as is described in Informed Consent Form). Participants were free to contact with the MBI instructor or a counsellor, during study period. The burden of participation (i.e. time investment in learning the mindfulness-based meditative training and extra study examinations) may be compensated by the possible benefits.

The present study has been carried through within the framework of a part-financed dissertation project with four sub-projects. The feasibility study, showing patients recruitment and flow through the study, with results of the MBI on symptoms and signs in patients with chronic heart failure is published [1].

The study has not prior been registered at clinicalTrial.gov, due to the nature of the interventional pilot study, as was original initiated as a part of a Master Thesis, and registration was not required at the time recruitment began in 2010. Also, it is not until now we realize the value to retrospectively register the study, when able to provide the new knowledge gained by the project in the sub-project II, III and IV.

The study has been conducted in several phases, including a pre-pilot phase and two pilot phases. In the pre-pilot phase, the study protocol with the Research Person Information (Informed Consent Form) was evaluated with patients randomly assigned to a MBI (n=3) or control group (n=3). Results on participants' experiences of the MBI, and the effects on the outcomes, were analyzed with a qualitative approach and described in a Master's thesis (in Swedish).

The present study protocol was approved in 2010, by the Regional Ethical Board in Gothenburg, Sweden (No. 265:10), with a few minor revisions, including tuning down the benefits, and the advice to review if possible, to reduce the number of instruments in the study.

All through the study has been performed according to the principles of the Declaration of Helsinki. All participants provided written and Informed Consent and signed the ICF before beginning the study, and were informed of the right of free withdrawal.

The first pilot phase lasted from 2010 to 2011. In February 2012 the study was approved for a doctoral student position, with research grants from the Centre for Person-Centred Care at the University of Gothenburg (GPCC). GPCC was founded by the Swedish Government´s grant for Strategic Research Areas, Care Sciences (Application to Swedish Council no. 2009-1088). The second phase of the study was conducted in 2013, called the "Main study", but the RCT was to be transformed to a feasibility study.

The Analysis plan into the dissertation project: Effects of a Mindfulness-Based Intervention on Symptoms and Signs, Well-being and Health in patients with Chronic Heart Failure, includes both qualitative and quantitative methods. Briefly, the original focus on qualitative research, shifted to emphasis quantitative methods. The original plan to use parametric methods, to compare the study groups, shifted to Non-parametric Mann-Whitney U test. Due to the small sample size, and the ordinal level of data. Statistical analysis was carried out in consultation with Healthmetrics, University of Gothenburg, Sweden. Two separate sets of outcome variables were constructed prior analysis. The first set was on symptoms and signs and included in published paper [1]. The other set is on the psychological outcomes (anxiety and depression), well-being, sense of coherence and health [paper II). Paper III is a qualitative: Experiences of Breathing and Shortness of Breath with Chronic Heart Failure - A descriptive and explorative study. The 4th paper is a Mixed-Method study on the effects of MBI on problematic shortness of breath experiences with heart failure.

Topics of research in this project may be relevant for many patients with heart failure and professionals. The reasons for delay of publishing results in the present study is several, what matters now is the ability to share the new knowledge on the effects of MBI on psychological distress and health in heart failure with patients and professionals all over the world. That is the heart goal for this application to ClinicalTrial.gov.

Intervention

Behavioral:
• Mindfulness-based intervention
Eight, 2-hour instructor-led MBI group sessions once a week for 8 weeks, combined with formal meditative training at home for 20 minutes per day, 6 days a week. Course material consists of facts booklet, weekly training manuals, audio recordings on a CD, with the five formal guided meditative exercises (body scan, breathing anchor, breathing space, mindful movements, sitting meditation). The weekly home-work also included informal training of being present in daily life activities. The program is provided according to the standard MBI protocol. Compared to MBSR and MBCT durations of formal meditative practices are shorter and no 'all-day in silence' session is included. Because of participants' physical limitations and safety, the 'mindful movements' sequence, is adapted and performed in a sitting position. Adherence to the MBI was followed by self-reported weekly training in manuals asked to be submitted at group sessions.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Heart rate	Change from baseline to follow-up at week 10, in heart rate (beats/min), will be measured in sitting position after rest (>5 min) using an automated non-invasive monitor (Omron Memory Intelli Sense, model 705 IT; Omron Healthcare, Hoofddorp, The Netherlands). With a lower heart rate frequency representing a better prognostic sign.	10 weeks
Other	Respiratory rate	Change from baseline to follow-up at week 10, in respiratory rate, will be assessed manually using the pulse clock, at rest within a set of 60 s. With a calmer breathing rate representing a better sign, and higher rates to be a worsening heart failure sign, as linked to fluid retention in the body and decompensation.	10 weeks
Other	Functional classification	Change from baseline to follow-up at week 10, in New York Heart Association (NYHA class). With the NYHA class based on patient-reported symptoms on five-point Likert scale (breathlessness and tiredness) as related to physical exertion. Patient response alternatives ranged from (1) 'I am never breathless/tired' to (5) 'when I am at rest', with each symptom reported separately. With a lower NYHA class indicating lower severity degree of symptoms and improved physical function.	10 weeks
Other	Breathlessness related to physical exertion	Change from baseline to follow-up at week 10, in the patient-reported severity of breathlessness related to physical activity, using five-point Likert scale. Patients' response alternatives ranged from: (1) asymptomatic 'I am never breathless'; (2) 'When I am walking up the stairs (one floor) or in a slope at normal pace'; (3) 'Walking at normal pace on a flat surface (< 200 m)'; (4) 'Walking slowly on flat surface (< 100 m) or during washing or dressing'; up to (5) 'When I am at rest'.	10 weeks
Other	Tiredness related to physical exertion	Change from baseline to follow-up at week 10, in the patient-reported severity of tiredness, related to physical activity, using five-point Likert scale. Patients' response alternatives ranged from (1) asymptomatic 'I am never tired'; (2) 'When I am walking up the stairs (one floor) or in a slope at normal pace'; (3) 'Walking at normal pace on a flat surface (< 200 m)'; (4) 'Walking slowly on flat surface (< 100 m) or during washing or dressing'; up to (5) ('When I am at rest').	10 weeks
Other	Functional capacity	Change from baseline to follow-up at week 10, measured in distance (in meter) walked at the 6-min walk test. With a longer distance walked in 6 minutes, indicating improved functional capacity. Additional outcome assessed as 'objective sign', in participants in the second phase of the study.	10 weeks
Other	Shortness of breath	Change from baseline to follow-up at week 10, will be measured and described in self-reported experiences of breathing and shortness of breath explored in semi structured interviews, guided by an extended assessment tool "Experiences of Breathing and Shortness of breath" (Exp-BeSoB), in development within the project. The Exp-BeSoB includes both open-ended questions, where participants are allowed to explore their own experiences in several dimensions, and pre-formulated descriptors, and self-rating scales related to shortness of breath experiences. With lower scores indicating alleviated breathing symptoms.	10 weeks
Other	Other symptoms	Change from baseline to follow-up at week 10, will be measured in six other self-reported symptoms (ankle swelling, impaired appetite; nausea, pain at rest/moving, thirst/dryness in the throat, and unsteadiness/dizziness) commonly reported by patients with chronic heart failure. Occurrence of symptom within a timeframe of "last week" ("no/yes"), and the degree of symptom severity self-reported by participants using 11-point numerical rating scale (NRS) ranging from 0 ("not at all bothersome") to 10 ("worst possible"), with higher rating degree indicating more severe symptom experiences.	10 weeks
Other	Health self-rated on Visual Analogue Scale	Change from baseline to follow-up at week 10, in health will be measured using self-rating scales. In the first pilot (2010 - 2011) health was also assessed on an ungraded vertical visual analog scale (VAS), with the anchor points "worse health" and "best health" (at the top of the scale). The scale was in 2013, changed into a horizontal 11-point numerical rating scale (NRS) ranging from 0 ("worst possible health") to 10 ("best possible health"). Due to different scale measures, outcome was not possible to include in statistical analysis. Health measures on VAS were used in the 2nd sub-project to identify outliers among participants who didn't answer the SF-36, in the first pilot.	10 weeks
Other	Well-being self-rated on Likert-scale	Change from baseline to follow-up at week 10, in well-being as measured on self-rating scales. In the first pilot (2010 - 2011) well-being was also assessed on a 5-point Likert scale (1-5), with the anchor points (1) "no well-being" and (5) "best possible well-being". The scale was in 2013, also changed into a horizontal 11-point numerical rating scale (NRS) ranging from 0 to 10 with the anchor points (1) "worst possible well-being" and (10) "best possible well-being". Due to different scale measures, outcome was not possible to include in statistical analysis.	10 weeks
Primary	Self-reported impact of fatigue	Change from baseline to follow-up at week 10, will be measured at the Fatigue Severity Scale (FSS), a self-administered questionnaire including nine items investigating the impact of disabling fatigue on daily functioning during the past week. Grading of each item ranges from 1 to 7, with the total possible fatigue sum score ranging from 9 to 63, and higher scores indicating higher levels of indexed impact of fatigue. The FSS had not previously been tested in a heart failure population, and no cut-off score was found. The FSS was provided at visits and answered at home, and sent in to University address.	10 weeks
Secondary	Anxiety	Change from baseline to follow-up at week 10, will be measured at the Hospital Anxiety and Depression Scale (HADS). The HADS is a self-administered questionnaire with two sub-scales to detect possible presence of anxiety (HADS-A) and/or depression (HADS-D). Both sub-scales include 7 items, with four-point scales ranging from 0 to 3, with total sum-score ranging from 0-21, and defined as 0-7 (normal), 8-10 (possible case), and 11-21 (probable case) of anxiety disorders or depression, and the patient in need of additional psychiatric treatment. Optimal cut-off for both subscales is set to =8. The HADS was provided at visits, answered at home, and sent to University address.	10 weeks
Secondary	Depression	Change from baseline to follow-up at week 10, will be measured at the Hospital Anxiety and Depression Scale (HADS). The HADS is a self-administered questionnaire with two sub-scales to detect possible presence of anxiety (HADS-A) and/or depression (HADS-D). Both sub-scales include 7 items, with four-point scales ranging from 0 to 3, with total sum-score ranging from 0-21, and defined as 0-7 (normal), 8-10 (possible case), and 11-21 (probable case) of anxiety disorders or depression, and the patient in need of additional psychiatric treatment. Optimal cut-off for both subscales is set to =8. The HADS was provided at visits, answered at home, and sent to University address.	10 weeks
Secondary	Psychological and General Well-Being	Change from baseline to follow-up at week 10, will be measured at the Psychological and General Well-Being (PGWB) index. The PGWB is a 22-item self-administered questionnaire designed to measure "self-representations of intrapersonal affective or emotional states reflecting a sense of subjective well-being or distress. The six response options were coded 1-6 in accordance with Swedish studies, and the total PGWB sum score was ranging from 22 to 132, with defined categories (1) score 22-82 (Severe distress); (2) score 83-94 (Moderate distress); score 95-132 (Positive well-being). The PGWB was provided at visits, answered at home, and sent in to University address.	10 weeks
Secondary	Sense of coherence	Change from baseline to follow-up at week 10, will be measured at the self-administered questionnaire Sense of coherence (SOC-13) total index. The SOC-13 consisting of 13 items, all with seven-point scale and two anchoring responses. With higher scores indicating higher personal capabilities to perceive the world and stressful events in life as comprehensible, manageable, and meaningful defined as high SOC. The psychometric tested Swedish version of SOC-13, and the total score categories defined as: 30-60 (Low SOC); 61-75 (Moderate SOC); 76-91 (High SOC) is used. The SOC-13 was provided at visits, answered at home, and sent in to University address.	10 weeks
Secondary	Health	Change from baseline to follow-up at week 10, on self-reported health, will be measured at the Swedish version of the 36-item Short Form Health Survey (SF-36) General Health (GH) Index. The SF-36 GH index consists of five items, with questions focusing participants' perception of their health, with five response choices each, and higher points indicating better health. The SF-36 questionnaire were included in the first phase (pilot 1), then temporary removed. The value of health status as measured in the SF-36, was reconsidered 2012 and the instrument was reinstated in 2013 (pilot 2). The SF-36 was provided at visits, answered at home, and sent in to University address.	10 weeks
Secondary	Self-reported symptoms of impaired sleep	Change from baseline to follow-up at week 10, will be measured at the Karolinska Sleep Questionnaire - sleep quality index (KSQ-sqi). Which is a sub-scale including four questions, with high scores indicating good sleep quality. The KSQ was provided at visits, answered at home, and sent to University address.	10 weeks
