Living with non-cardiac chest pain - An inductive qualitative interview study of spouses' perspectives.

AIM: To explore spouses' experiences of living with a partner suffering from non-cardiac chest pain (NCPP). DESIGN: An inductive qualitative study. METHODS: Individual interviews (n = 10) were performed with spouses of partners having NCCP and cardiac anxiety. The analysis was performed according to Patton's guide for content analysis of qualitative data. RESULTS: Three categories and seven subcategories were identified. First, 'a feeling of being neglected', where spouses felt ignored by healthcare professionals and excluded by their partners. Secondly, 'a tension between hope and despair' encompassed feelings of faith, support, unpreparedness for chest pain and situational frustration. Lastly, in 'a threat to ordinary life', spouses noted chest pain-induced changes impacting daily life, finances, leisure and relationships. To conclude, NCCP in partners significantly affects their spouses emotionally and practically. Spouses felt neglected and isolated, oscillating between hope and despair and experiencing faith, powerlessness and frustration. They also faced challenges in daily life and relationships.

Long-term effects and predictors of change of internet-delivered cognitive behavioural therapy on cardiac anxiety in patients with non-cardiac chest pain: a randomized controlled trial.

BACKGROUND: Approximately half of patients who seek care at Emergency Departments due to chest pain are diagnosed with Non-Cardiac Chest Pain (NCCP). Concerns for heart disease and misinterpretation of the symptoms increase cardiac anxiety and have a negative impact on patients' lives. Psychological interventions such as internet-delivered cognitive behavioral therapy (iCBT) are effective in treating psychological conditions such as anxiety, by helping patients to learn how to manage chest pain. AIMS: To evaluate the effects of a nurse-led iCBT program on cardiac anxiety and secondary outcomes, as bodily sensations, depressive symptoms, health-related quality of life and chest pain frequency in patients with NCCP at 6- and 12-month follow-up, and to explore predictors that can have impact on the effects of the iCBT program on psychological distress. METHODS: A longitudinal study of a Randomized Controlled Trial (RCT) evaluating the long-term effects of an iCBT program (n = 54) in patients with NCCP, compared to psychoeducation (n = 55). The primary outcome, cardiac anxiety was measured using the Cardiac Anxiety Questionnaire (CAQ), and the secondary outcomes were measured with The Body Sensations Questionnaire (BSQ), Patient Health Questionnaire-9 (PHQ-9), The EuroQol Visual Analog Scale (EQ-VAS) and a self-developed question to measure chest pain frequency. All measurements were performed before and after the intervention, and 3, 6 and 12 months after the intervention. Linear mixed model was used to test between-group differences in primary and secondary outcomes and multiple regression analysis was used to explore factors that may have an impact on the treatment effect of iCBT on cardiac anxiety. RESULTS: A total of 85% (n = 93/109) participants completed the 12-month follow-up. Mixed model analysis showed no statistically significant interaction effect of time and group between the iCBT and psychoeducation groups regarding cardiac anxiety over the 12-month follow-up. However, there was a statistically significant interaction effect of time and group (p = .009) regarding chest pain frequency favouring the iCBT group. In addition, we found a group effect in health-related quality of life (p = .03) favouring the iCBT group. The regression analysis showed that higher avoidance scores at baseline were associated with improvement in cardiac anxiety at 12-month follow-up. CONCLUSIONS: Cardiac anxiety was reduced in patients with NCCP, but iCBT was not more effective than psychoeducation. Patients with a high tendency to avoid activities or situations that they believe could trigger cardiac symptoms may benefit more from psychological interventions targeting cardiac anxiety. TRIAL REGISTRATION: The trial was registered at ClinicalTrials.gov NCT03336112 on 08/11/2017.

Healthcare use in patients with cardiovascular disease and depressive symptoms - The impact of a nurse-led internet-delivered cognitive behavioural therapy program. A secondary analysis of a RCT.

Background: Depressive symptoms in patients with cardiovascular disease (CVD) can lead to increased healthcare use. In a randomized controlled trial (ClinicalTrials.gov, NCT02778074), we reported that a 9-week internet-delivered cognitive behavioural therapy (iCBT) program (n = 72) compared to an online discussion forum (ODF) (n = 72) had moderate to large effect on depression in CVD outpatients. In this secondary analysis, we aimed to describe and compare the effect of iCBT compared to ODF regarding healthcare use and to identify factors impacting healthcare use in these groups. Methods: Data on healthcare use were retrieved from care data registries in five hospitals in Southeastern Sweden. Results: The year prior to intervention, the iCBT group had a mean of 31 outpatient clinic/primary care contacts per patient compared with 21 contacts the year after. The corresponding numbers for the ODF group were 37 and 25. The decrease was 32 % in both groups and did not differ significantly (p = 0.261 and p = 0.354) between the groups. Regarding hospital admissions, the iCBT group had 0.8 admissions per patient the year before and 0.6 the year after the intervention, a decrease by 25 %, whereas the ODF group had 1.1 and 0.6 admissions respectively, a decrease by 45 %. The difference was not statistically significant (p = 0.270 and p = 0.883) between the groups. Improvement in depressive symptoms post intervention were significantly (Beta = 0.459, p = 0.047) associated with a decrease in number of outpatient contacts in the iCBT group. In the ODF group, better mental health-related quality of life post intervention was significantly (Beta = -0.429, p = 0.045) associated with a decrease in number of hospital admissions. Conclusion: Reduced depressive symptom scores following intervention were associated with lower outpatient service use, but iCBT was not superior compared to ODF. This implicates that reducing depression in CVD patients, regardless of the type of internet-delivered intervention used, is important since it may reduce healthcare use in these patients.

The effects of internet-based cognitive behavior therapy for depression in cardiovascular disease on symptoms of anxiety: A secondary analysis of a randomized trial.

AIMS: The aims of this study were to evaluate: (I) the short- and long-term effects of the internet-based cognitive behavior (iCBT) program on symptoms of distress and fear disorder in CVD patients, and (II) the association between changes in depression and changes in symptoms of distress and fear disorder from baseline to 12-months follow-up. METHODS AND RESULTS: Secondary analysis of data collected in a randomized controlled study evaluating the effects on depression of an iCBT program compared to an online discussion forum (ODF) in CVD patients (n = 144). Data were collected at baseline, at post-intervention (nine weeks), and at 6- and 12-month follow-up.The results showed that symptoms of distress disorder were statistically significantly more reduced in the iCBT group than the ODF group. For symptoms of fear disorder, no differences were found except for avoidance, which showed a statistically significant reduction in the iCBT group. The long-term analysis in the iCBT group showed that CAQ total score and fear decreased from baseline to 6- and 12-months follow-up respectively. Avoidance and attention both decreased statistically significantly from baseline to post-intervention, but not between post-intervention and 12-months follow-up. CONCLUSION: The results suggest that the iCBT program targeted depression in CVD patients successfully reduced symptoms of distress disorder, and to a lesser extent symptoms of fear disorder. Change in depression was more strongly associated with change in distress than change in fear disorder. REGISTRATION: clinicaltrials.gov NCT02778074.

Mobile care - a possible future for emergency care in Sweden.

INTRODUCTION: Provision of mobile care at the home of patients appears to become necessary as the population becomes increasingly older. But there are challenges in moving emergency care from hospitals to the home of patients. The aim of the study was therefore to describe the experiences of the mobile care in Sweden. METHOD: Semi structured interviews were conducted with 12 persons with experience of mobile care in Sweden, such as nurses, physicians, civil servants and politicians. Qualitative latent content analysis was used as an analysis method. RESULT: The results show that cooperation is of utmost importance to achieve functioning mobile care. Cooperation both on an inter-organizational level and on a close team-work is required for all of the involved parties in mobile care to take on a joint responsibility for the patient. As mobile care is primarily provided to elderly multimorbid patients, a comprehensive view on patient care is required in which the patient and their relatives experience security. CONCLUSION: Mobile care is seen as a moving care that comes to the seeking person and not the other way around. The resources are distributed where they make the most use, that is, closest to the individual. Mobile care is seen as a complement to the traditional hospital care. This means a different way of working that requires close collaboration between different categories of personnel and organizations, where there should not be any discussions about boundaries, rather, the discussion should include patient's needs and situation instead.

Costs of an Off-the-Shelf Exergame Intervention in Patients with Heart Failure.

Objectives: Exergaming is promising for patients with heart failure who are less inclined to start or maintain exercise programs involving traditional modes of physical activity. Although no effect on exercise capacity was found for an off-the-shelf exergame, it is important to gain insights into aspects related to costs to develop such interventions further. Materials and Methods: In a randomized controlled trial, the Heart Failure Wii study (HF-Wii study), the intervention group (exergame group) received an introduction to the exergame, the exergame was installed at home and help was offered when needed for 3 months. Patients received telephone follow-ups at 2, 4, 8, and 12 weeks after the installation. The control group (motivational support group) received activity advice and telephone follow-ups at 2, 4, 8, and 12 weeks. We collected data on hospital use and costs, costs of the exergame intervention, patient time-related costs, and willingness to pay. Results: No significant differences were found between the exergame group (n = 300) versus the motivational support group (n = 305) in hospital use or costs (1-year number of hospitalizations: P = 0.60, costs: P = 0.73). The cost of the intervention was 190 Euros, and the patient time-related costs were 98 Euros. Of the total estimated costs for the intervention, 287 Euros, patients were willing to pay, on average, 58%. Conclusion: This study shows that the costs of an intervention using an off-the-shelve exergame are relatively low and that the patients were willing to pay for more than half of the intervention costs. The trial is registered in ClinicalTrials.gov (NCT01785121).

Experience of internet-delivered cognitive behavioural therapy among patients with non-cardiac chest pain.

AIMS AND OBJECTIVE: To explore the experiences of patients with non-cardiac chest pain and cardiac anxiety regarding participation in an internet-delivered cognitive behavioural therapy program. BACKGROUND: Non-cardiac chest pain is common and leads to cardiac anxiety. Internet-delivered cognitive behavioural therapy may be a possible option to decrease cardiac anxiety in these patients. We have recently evaluated the effect of an internet-delivered cognitive behavioural therapy program on cardiac anxiety. DESIGN: An inductive qualitative study using content analysis and the COREQ checklist. METHODS: Semi-structured interviews with 16 Swedish patients, who had participated in the internet-delivered cognitive behavioural therapy program. RESULTS: Three categories were found. The first, 'Driving factors for participation in the internet-delivered cognitive behavioural therapy program' described the impact of pain on their lives and struggle that led them to participating in the program. The second, 'The program as a catalyst' described that the program was helpful, trustworthy and useful and the last category, 'Learning to live with chest pain' described the program as a tool for gaining the strength and skills to live a normal life despite chest pain. CONCLUSIONS: The program was experienced as an opportunity to return to a normal life. The program was perceived as helpful, trustworthy and useful, which helped the participants challenge their fear of chest pain and death, and gain strength and new insights into their ability to live a normal life. RELEVANCE TO CLINICAL PRACTICE: A tailored internet-delivered cognitive behavioural therapy program delivered by a nurse therapist with clinical experience of the patient group is important to improve cardiac anxiety. PATIENT OR PUBLIC CONTRIBUTION: Patients or the general public were not involved in the design, analysis or interpretation of the data of this study, but two patients with experience of non-cardiac chest pain were involved in the development of the pilot study.

Internet-Based Cognitive Behavioral Therapy and its Association With Self-efficacy, Depressive Symptoms, and Physical Activity: Secondary Analysis of a Randomized Controlled Trial in Patients With Cardiovascular Disease.

BACKGROUND: In patients with cardiovascular disease (CVD), knowledge about the associations among changes in depressive symptoms, self-efficacy, and self-care activities has been requested. This is because such knowledge can be helpful in the design of behavioral interventions aimed to improve self-efficacy, reduce depressive symptoms, and improve performance of self-care activities in CVD patients. OBJECTIVE: We aim to evaluate if internet-based cognitive behavioral therapy (iCBT) improves self-efficacy and explore the relationships among changes in depressive symptoms, self-efficacy, and physical activity, as well as the influence of iCBT on these relationships. METHODS: This study received funding in January 2015. Participant recruitment took place between January 2017 and February 2018, and the main findings were published in 2019. This study is a secondary analysis of data collected in a randomized controlled study evaluating the effects of a 9-week iCBT program compared to an online discussion forum (ODF) on depressive symptoms in patients with CVD (N=144). Data were collected at baseline and at the 9-week follow-up. Analysis of covariance was used to evaluate the differences in self-efficacy between the iCBT and ODF groups. Structural equation modeling explored the relationships among changes in depressive symptoms, self-efficacy, and physical activity, as well as the influence of iCBT on these relationships. RESULTS: At follow-up, a significant difference in the increase in self-efficacy favoring iCBT was found (P=.04, Cohen d=0.27). We found an indirect association between changes in depressive symptoms and physical activity (ß=-.24, P<.01), with the change in self-efficacy acting as a mediator. iCBT had a direct effect on the changes in depressive symptoms, which in turn influenced the changes in self-efficacy (ß=.23, P<.001) and physical activity (ß=.12, P<.001). CONCLUSIONS: Self-efficacy was improved by iCBT. However, the influence of iCBT on self-efficacy and physical activity was mostly mediated by improvements in depressive symptoms.

The experience of participating in an internet-based cognitive behavioral therapy program among patients with cardiovascular disease and depression: a qualitative interview study.

BACKGROUND: Depression in conjunction with cardiovascular disease (CVD) is associated with worsening in CVD, higher mortality, and poorer quality of life. Despite the poor outcomes there is a treatment gap of depression in CVD patients. Recently we found that an Internet-based cognitive behavioral therapy (iCBT) tailored for CVD patients led to reduced symptoms of depression. However, we still have little knowledge about CVD patients' experiences of working with iCBT. The aim of this study was therefore to explore CVD patients' experiences of engaging in a tailored iCBT program. METHODS: A qualitative interview study using inductive thematic analysis. Data was obtained from 20 patients with CVD and depressive symptoms who had participated in a randomized controlled trial (RCT) evaluating the impact of a nine-week iCBT program on depression. RESULTS: Three main themes emerged: (1) Taking control of the disease, (2) Not just a walk in the park, and (3) Feeling a personal engagement with the iCBT program. The first theme included comments that the tailored program gave the patients a feeling of being active in the treatment process and helped them achieve changes in thoughts and behaviors necessary to take control of their CVD. The second theme showed that patients also experienced the program as demanding and emotionally challenging. However, it was viewed as helpful to challenge negative thinking about living with CVD and to change depressive thoughts. In the third theme patients reported that the structure inherent in the program, in the form of organizing their own health and the scheduled feedback from the therapist created a feeling of being seen as an individual. The feeling of being acknowledged as a person also made it easier to continuously work with the changes necessary to improve their health. CONCLUSIONS: Engaging in an iCBT program tailored for patients with CVD and depression was by the patients perceived as helpful in the treatment of depression. They experienced positive changes in emotions, thoughts, and behaviors which a result of learning to take control of their CVD, being confirmed and getting support. The patients considered working with the iCBT program as demanding and emotionally challenging, but necessary to achieve changes in emotions, thoughts, and behaviors.

Cost-effectiveness of internet-delivered cognitive behavioural therapy in patients with cardiovascular disease and depressive symptoms: secondary analysis of an RCT.

INTRODUCTION: Cost-effectiveness evaluations of psychological interventions, such as internet-delivered cognitive behavioural therapy (iCBT) programmes, in patients with cardiovascular disease (CVD) are rare. We recently reported moderate to large effect sizes on depressive symptoms in CVD outpatients following a 9-week iCBT programme compared with an online discussion forum (ODF), in favour of iCBT. In this paper, we evaluate the cost-effectiveness of this intervention. METHODS: Cost-effectiveness analysis of a randomised controlled trial. The EQ-5D-3L was used to calculate quality-adjusted life-years (QALYs). Data on healthcare costs were retrieved from healthcare registries. RESULTS: At 12-month follow-up, the QALY was significantly higher in iCBT compared with the ODF group (0.713 vs 0.598, p=0.007). The mean difference of 0.115 corresponds with 42 extra days in best imaginable health status in favour of the iCBT group over the course of 1 year. Incremental cost-effectiveness ratio (ICER) for iCBT versus ODF was €18 865 per QALY saved. The cost-effectiveness plane indicated that iCBT is a cheaper and more effective intervention in 24.5% of the cases, and in 75% a costlier and more effective intervention than ODF. Only in about 0.5% of the cases, there was an indication of a costlier, but less effective intervention compared with ODF. CONCLUSIONS: The ICER of €18 865 was lower than the cost-effectiveness threshold range of €23 400-€35 100 as proposed by the NICE guidelines, suggesting that the iCBT treatment of depressive symptoms in patients with CVD is cost-effective.

Effects of Internet-delivered cognitive behavioural therapy adapted for patients with cardiovascular disease and depression: a long-term follow-up of a randomized controlled trial at 6 and 12 months posttreatment.

BACKGROUND: Internet-based cognitive behavioural treatment (iCBT) has shown positive short-term effects on depression in patients with cardiovascular disease (CVD). However, knowledge regarding long-term effects and factors that may impact the effect of iCBT is lacking. AIMS: This study therefore sought (i) to evaluate the effect of iCBT on depression in CVD patients at 6- and 12-month follow-ups and (ii) to explore factors that might impact on the effect of iCBT on change in depression at 12-month follow-up. METHODS AND RESULTS: A longitudinal follow-up study of a randomized controlled trial evaluating the effects of a 9-week iCBT programme compared to an online discussion forum (ODF) on depression in CVD patients (n = 144). After 9 weeks, those in the ODF group were offered the chance to take part in the iCBT programme. The Patient Health Questionnaire (PHQ-9) and the Montgomery-Åsberg Depression Rating Scale-self-rated version (MADRS-S) measured depression at baseline, 9 weeks, 6 months, and 12 months. Linear mixed model and multiple regression analysis were used for statistical computing. The iCBT programme significantly improved depression at 9-week follow-up and this was stable at 6- and 12-month follow-ups (PHQ-9 P = 0.001, MADRS-S P = 0.001). Higher levels of depression at baseline and a diagnosis of heart failure were factors found to impact the effect of iCBT on the change in depression. CONCLUSION: A 9-week iCBT programme in CVD patients led to long-term improvement in depression. Higher levels of depression scores at baseline were associated with improvement in depression, whereas heart failure had opposite effect. CLINICAL TRIAL: The trial is registered at ClinicalTrials.gov, NCT02778074.

The Effect of Internet-Delivered Cognitive Behavioral Therapy Versus Psychoeducation Only on Psychological Distress in Patients With Noncardiac Chest Pain: Randomized Controlled Trial.

BACKGROUND: Patients with recurrent episodes of noncardiac chest pain (NCCP) experience cardiac anxiety as they misinterpret the pain to be cardiac related and avoid physical activity that they think could threaten their lives. Psychological interventions, such as internet-delivered cognitive behavioral therapy (iCBT), targeting anxiety can be a feasible solution by supporting patients to learn how to perceive and handle their chest pain. OBJECTIVE: This study aims to evaluate the effects of a nurse-led iCBT program on cardiac anxiety and other patient-reported outcomes in patients with NCCP. METHODS: Patients with at least two health care consultations because of NCCP during the past 6 months, and who were experiencing cardiac anxiety (Cardiac Anxiety Questionnaire score ≥24), were randomized into 5 weeks of iCBT (n=54) or psychoeducation (n=55). Patients were aged 54 (SD 17) years versus 57 (SD 16) years and were mainly women (32/54, 59% vs 35/55, 64%). The iCBT program comprised psychoeducation, mindfulness, and exposure to physical activity, with weekly homework assignments. The primary outcome was cardiac anxiety. The secondary outcomes were fear of bodily sensations, depressive symptoms, health-related quality of life, and chest pain frequency. Intention-to-treat analysis was applied, and the patients were followed up for 3 months. Mixed model analysis was used to determine between-group differences in primary and secondary outcomes. RESULTS: No significant differences were found between the iCBT and psychoeducation groups regarding cardiac anxiety or any of the secondary outcomes in terms of the interaction effect of time and group over the 3-month follow-up. iCBT demonstrated a small effect size on cardiac anxiety (Cohen d=0.31). In the iCBT group, 36% (16/44) of patients reported a positive reliable change score (≥11 points on the Cardiac Anxiety Questionnaire), and thus an improvement in cardiac anxiety, compared with 27% of (13/48) patients in the psychoeducation group. Within-group analysis showed further significant improvement in cardiac anxiety (P=.04) at the 3-month follow-up compared with the 5-week follow-up in the iCBT group but not in the psychoeducation group. CONCLUSIONS: iCBT was not superior to psychoeducation in decreasing cardiac anxiety in patients with NCCP. However, iCBT tends to have better long-term effects on psychological distress, including cardiac anxiety, health-related quality of life, and NCCP frequency than psychoeducation. The effects need to be followed up to draw more reliable conclusions. TRIAL REGISTRATION: ClinicalTrials.gov NCT03336112; https://www.clinicaltrials.gov/ct2/show/NCT03336112.

How Healthcare Professionals in Cardiac Care Address Depressive Symptoms: Experiences of Patients With Cardiovascular Disease.

BACKGROUND: Depressive symptoms are common in patients with cardiovascular disease (CVD) and are associated with a poorer quality of life and prognosis. Despite the high prevalence and negative consequences, the recognition of depressive symptoms is low. More knowledge about patients' perceptions of how depressive symptoms are addressed by healthcare professionals is therefore needed. OBJECTIVES: The aim of this study was to explore the experiences of patients with CVD of how healthcare professionals address and manage depressive symptoms in clinical cardiac care encounters. METHODS: A qualitative, semistructured interview study was performed. Data were analyzed using inductive thematic analysis. RESULTS: In total, 20 patients with CVD previously treated for depressive symptoms were included (mean age, 62 [range, 34-79] years; 45% women). Three main themes emerged: (1) "not being seen as a whole person," (2) "denying depressive symptoms," and (3) "being provided with help." The patients perceived that healthcare professionals mainly focused on somatic symptoms and disregarded their need for help for depressive symptoms when patients raised the issue. Some patients stated that they received help for depressive symptoms, but this depended on the patients' own ability to communicate their needs and/or having social support that could alert them to the importance of doing so. Patients also described that they downplayed the burden of depressive symptoms and/or did not recognize themselves as having depressive symptoms. CONCLUSION: Depressive symptoms were overlooked in patients with CVD, and psychological needs had not been met. A good ability to address needs and having good social support were useful for receiving help with depressive symptoms.

The associations between psychological distress and health-related quality of life in patients with non-cardiac chest pain.

BACKGROUND: Recurrent chest pain episodes with no clear explanation may affect patients' psychological wellbeing and health-related quality of life (HRQoL) negatively. Despite the fact that a significant amount of patients with non-cardiac chest pain (NCCP) might have a history of Cardiac Disease (CD), there is today a lack of knowledge on how CD influences the association between psychological wellbeing and HRQoL in patients with NCCP. Therefore, the aim of this study is to describe HRQoL in patients with NCCP, with or without history of CD, and to explore the association between HRQoL and cardiac anxiety, depressive symptoms, fear of body sensations and somatization. METHODS: Five hundred fifty-two patients discharged with NCCP from four hospitals in Southeast Sweden completed the EQ-5D, Cardiac Anxiety Questionnaire, Patient Health Questionnaire-9, Body Sensations Questionnaire, and Patient Health Questionnaire-15. RESULTS: Fifty precent reported at least moderate problems regarding pain/discomfort and 25% reported at least moderate problems in the HRQoL dimensions mobility, usual activities, and anxiety/depression. Patients with NCCP and history of CD reported significantly lower HRQoL (p ≤ 0.05) compared to patients with NCCP without CD. In the total study population, cardiac anxiety, depressive symptoms, and somatization had weak significant negative associations (beta = 0.187-0.284, p < 0.001) with HRQoL. In patients with history of CD, the association between depressive symptoms and HRQoL was moderate (beta = - 0.339, p < 0.001), compared to weak association in patients without CD (beta = - 0.193, p < 0.001). On the other hand, the association between cardiac anxiety and HRQoL was weak in both patients with history of CD (beta = - 0.156, p = 0.05), and in those without (beta = - 0.229, p < 0.001). CONCLUSIONS: Patients with NCCP, in particular those with history of CD, reported low levels of HRQoL, which was associated with psychological distress. This should be considered when developing psychological interventions aiming to improve HRQoL in patients with NCCP.

An Internet-Based Cognitive Behavioral Therapy Program Adapted to Patients With Cardiovascular Disease and Depression: Randomized Controlled Trial.

BACKGROUND: Depression is a common cause of reduced well-being and prognosis in patients with cardiovascular disease (CVD). However, there is a lack of effective intervention strategies targeting depression. OBJECTIVE: The study aimed to evaluate the effects of a nurse-delivered and adapted internet-based cognitive behavioral therapy (iCBT) program aimed at reducing depression in patients with CVD. METHODS: A randomized controlled trial was conducted. A total of 144 patients with CVD with at least mild depression (Patient Health Questionnaire-9 [PHQ-9] score ≥5) were randomized 1:1 to a 9-week program of iCBT (n=72) or an active control participating in a Web-based discussion forum (online discussion forum [ODF], n=72). The iCBT program, which included 7 modules, was adapted to fit patients with CVD. Nurses with an experience of CVD care provided feedback and a short introduction to cognitive behavioral therapy. The primary outcome, depression, was measured using PHQ-9. Secondary outcomes were depression measured using the Montgomery-Åsberg Depression Rating Scale-self-rating version (MADRS-S), health-related quality of life (HRQoL) measured using Short Form 12 (SF-12) survey and EuroQol Visual Analogue Scale (EQ-VAS), and the level of adherence. An intention-to-treat analysis with multiple imputations was used. Between-group differences in the primary and secondary outcomes were determined by the analysis of covariance, and a sensitivity analysis was performed using mixed models. RESULTS: Compared with ODF, iCBT had a significant and moderate treatment effect on the primary outcome depression (ie, PHQ-9; mean group difference=-2.34 [95% CI -3.58 to -1.10], P<.001, Cohen d=0.62). In the secondary outcomes, compared with ODF, iCBT had a significant and large effect on depression (ie, MADRS-S; P<.001, Cohen d=0.86) and a significant and moderate effect on the mental component scale of the SF-12 (P<.001, Cohen d=0.66) and the EQ-VAS (P<.001, Cohen d=0.62). Overall, 60% (n=43) of the iCBT group completed all 7 modules, whereas 82% (n=59) completed at least half of the modules. No patients were discontinued from the study owing to a high risk of suicide or deterioration in depression. CONCLUSIONS: Nurse-delivered iCBT can reduce depression and improve HRQoL in patients with CVD, enabling treatment for depression in their own homes and at their preferred time.

The associations between psychological distress and healthcare use in patients with non-cardiac chest pain: does a history of cardiac disease matter?

BACKGROUND: Psychological distress such as somatization, fear of body sensations, cardiac anxiety and depressive symptoms is common among patients with non-cardiac chest pain, and this may lead to increased healthcare use. However, the relationships between the psychological distress variables and healthcare use, and the differences in relation to history of cardiac disease in these patients has not been studied earlier. Therefore, our aim was to explore and model the associations between different variables of psychological distress (i.e. somatization, fear of body sensations, cardiac anxiety, and depressive symptoms) and healthcare use in patients with non-cardiac chest pain in relation to history of cardiac disease. METHODS: In total, 552 patients with non-cardiac chest pain (mean age 64 years, 51% women) responded to the Patient Health Questionnaire-15, Body Sensations Questionnaire, Cardiac Anxiety Questionnaire, Patient Health Questionnaire-9 and one question regarding number of healthcare visits. The relationships between the psychological distress variables and healthcare visits were analysed using Structural Equation Modeling in two models representing patients with or without history of cardiac disease. RESULTS: A total of 34% of the patients had previous cardiac disease. These patients were older, more males, and reported more comorbidities, psychological distress and healthcare visits. In both models, no direct association between depressive symptoms and healthcare use was found. However, depressive symptoms had an indirect effect on healthcare use, which was mediated by somatization, fear of body sensations, and cardiac anxiety, and this effect was significantly stronger in patients with history of cardiac disease. Additionally, all the direct and indirect effects between depressive symptoms, somatization, fear of body sensations, cardiac anxiety, and healthcare use were significantly stronger in patients with history of cardiac disease. CONCLUSIONS: In patients with non-cardiac chest pain, in particular those with history of cardiac disease, psychological mechanisms play an important role for seeking healthcare. Development of interventions targeting psychological distress in these patients is warranted. Furthermore, there is also a need of more research to clarify as to whether such interventions should be tailored with regard to history of cardiac disease or not.

Guided Internet-delivered cognitive behavioural therapy in patients with non-cardiac chest pain - a pilot randomized controlled study.

BACKGROUND: Patients with recurrent episodes of non-cardiac chest pain may experience cardiac anxiety and avoidance behavior, leading to increased healthcare utilization. These patients might benefit from help and support to evaluate the perception and management of their chest pain. The purpose of this study was to test the feasibility of a short guided Internet-delivered cognitive behavioural therapy (CBT) program and explore the effects on cardiac anxiety, fear of body sensations, depressive symptoms, and chest pain in patients with non-cardiac chest pain, compared with usual care. METHODS: A pilot randomized controlled study was conducted. Fifteen patients with non-cardiac chest pain with cardiac anxiety or fear of body sensations, aged 22-76 years, were randomized to intervention (n = 7) or control (n = 8) groups. The four-session CBT program contained psychoeducation, physical activity, and relaxation. The control group received usual care. Data were collected before and after intervention. RESULTS: Five of seven patients in the intervention group completed the program, which was perceived as user-friendly with comprehensible language, adequate and varied content, and manageable homework assignments. Being guided and supported, patients were empowered and motivated to be active and complete the program. Patients in both intervention and control groups improved with regard to cardiac anxiety, fear of body sensations, and depressive symptoms, but no significant differences were found between the groups. CONCLUSIONS: The Internet-delivered CBT program seems feasible for patients with non-cardiac chest pain, but needs to be evaluated in larger groups and with a longer follow-up period.

Depressive Symptoms, Cardiac Anxiety, and Fear of Body Sensations in Patients with Non-Cardiac Chest Pain, and Their Relation to Healthcare-Seeking Behavior: A Cross-Sectional Study.

BACKGROUND: Patients with non-cardiac chest pain (NCCP) suffer from recurrent chest pain and make substantial use of healthcare resources. OBJECTIVE: To explore the prevalence of depressive symptoms, cardiac anxiety, and fear of body sensations in patients discharged with a NCCP diagnosis; and to describe how depressive symptoms, cardiac anxiety, and fear of body sensations are related to each other and to healthcare-seeking behavior. METHODS: Cross-sectional design. Data were collected between late October 2013 and early January 2014 in 552 patients with NCCP from four hospitals in southeast Sweden, using the Patient Health Questionnaire-9, Cardiac Anxiety Questionnaire, and Body Sensations Questionnaire. RESULTS: About 26 % (n = 141) of the study participants reported at least moderate depressive symptoms, 42 % (n = 229) reported at least moderate cardiac anxiety, and 62 % (n = 337) reported some degree of fear of body sensations. We found strong positive relationships between depressive symptoms and cardiac anxiety (r s = 0.49; P < 0.01), depressive symptoms and fear of body sensations (r s = 0.50; P < 0.01), and cardiac anxiety and fear of body sensations (r s = 0.56; P < 0.01). About 60 % of the participants sought care because of chest pain once, 26 % two or three times, and the rest more than three times. In a multivariable regression analysis, and after adjustment for multimorbidity, cardiac anxiety was the only variable independently associated with healthcare-seeking behavior. CONCLUSION: Patients with NCCP and many healthcare consultations had high levels of depressive symptoms and cardiac anxiety, and moderate levels of fear of body sensations. Cardiac anxiety had the strongest relationship with healthcare-seeking behavior and may therefore be an important target for intervention to alleviate suffering and to reduce healthcare use and costs.
