Multisymptom Profile Predicts Increased Risk of Poor Outcomes After Initial Placement of Implantable Cardioverter Defibrillator

CONTEXT

Patients with implantable cardioverter defibrillators (ICDs) are at risk for multiple physical and psychological symptoms. Identification of specific symptom profiles associated with poor outcomes may elucidate novel strategies to enhance symptom management.

OBJECTIVES

The objectives were to determine common symptoms after initial ICD implantation, identify classes of individuals with similar symptom profiles, describe patient characteristics associated with different symptom profiles, and determine if symptom profiles at hospital discharge predicted outcomes three and 12 months after implantation.

METHODS

This was a secondary data analysis of a randomized controlled trial that compared patient + partner versus patient-only interventions designed to help patients manage symptoms, prepare for ICD shocks, and resume daily activities. Symptoms were measured with the Patient Concerns Assessment. Latent class regression analysis was used to identify symptom classes at baseline, three-month, and 12-month follow-up. Associations between patient characteristics, class membership, and outcomes were examined using chi-square, analysis of variance, and Poisson regression.

RESULTS

The study included 301 patients (74% male, mean age 64 ± 11.9 years). Three classes were identified: Multi-Symptom (N = 119, 40%), Tired-Rundown (N = 130, 43%), and Mostly Asymptomatic (N = 52, 17%). Patients in the Multi-Symptom class were younger (59.9 years, P < 0.001) and reported more anxiety (P < 0.001) and depression (P < 0.01) than the other classes. Membership in the Multi-Symptom class predicted lower quality of life and resulted in nearly double the rate of hospitalizations after 12 months (P = 0.02, IRR 1.9).

CONCLUSION

Evaluation of symptom profiles after ICD implantation offers a promising strategy for identifying patients at risk for poor health outcomes.

Compromised Sexual Health Among Male Patients With Implantable Cardioverter Defibrillator: A Cross-Sectional Questionnaire Study

Introduction

In cardiac patients with implantable cardioverter defibrillator (ICD), sexual function is sparsely described.

Aim

To determine the prevalence and distribution of sexual dysfunction, and to describe whether primary or secondary prophylactic ICD indication and antitachycardia pacing (ATP) or shock is associated with sexual function.

Methods

A cross-sectional survey of men with an implanted ICD was conducted at 2 university hospitals in Denmark. Inclusion criteria were men over the age of 18 with an ICD. Exclusion criterion was no partner.

Main Outcome Measure

Sexual function was assessed by the International Index of Erectile Function questionnaire and data on implantation indication (primary/secondary prevention) and therapy such as ATP and shock (both appropriate and inappropriate) was obtained from the Danish ICD Register.

Results

Data from 415 questionnaires were analyzed (response rate 50.2%). Patients had a mean age of 63.9±12.1 years. Erectile dysfunction (ED) was present in 70% of patients, orgasmic dysfunction was present in 57.9% of patients, 82.8% had reduced sexual desire, 85.8% had intercourse satisfaction problems, and 76.9% experienced overall satisfaction problems (non-validated metric except for ED). Patients with an ICD on primary prophylactic indication had more sexual dysfunction and ED compared with patients with an ICD on secondary prophylactic indication. ATP therapy, but not shock, was associated with more ED.

Conclusion

Sexual dysfunction is common in patients with ICD and is not limited to ED, but also orgasmic function, desire, intercourse, and overall satisfaction are affected. Primary prophylactic ICD indication and ATP, but not shock therapy, is associated with compromised sexual function.

Exploring the Patient's Experiences of Learning to Live with an Implantable Cardioverter Defibrillator (ICD) from One UK Centre: A Qualitative Study

BACKGROUND

International expansion of indications for implantable cardioverter defibrillator (ICD) implant means increasing numbers of patients with devices worldwide. However, smaller numbers of patients with ICDs in the UK has meant that clinical expertise available to care for this specialized group is limited. Whilst North American patients' experiences of living with an ICD are well documented, European perspectives remain underrepresented.

AIM

The aim of this study was to explore and describe patient's experiences around the time of their ICD device implant and after they returned home from one UK centre.

METHODS AND RESULTS

Eligible patients were recruited from one regional cardiothoracic centre and interviewed in their own homes using semi-structured schedules. Analysis of data elicited three themes; non-individualised nature of information, adjustments to living with the device and future outlook. Unique findings identified were; (a) concealment of concerns and symptoms; (b) funding issues; and (c) unavailability of appropriate support and advice during and after time in hospital.

CONCLUSION

Individualized care and support for these ICD patients appeared lacking according to respondents. Opportunities to discuss concerns appeared non-existent, which may indicate that UK patients are disadvantaged in the domain of psychological support compared with their European and North American counterparts. Findings remain tentative until explored with a larger, more representative and international sample.

Partners of ICD Patients—An Exploratory Study of Their Experiences

BACKGROUND

The experiences of partners who care for and support the needs of a loved one with an implantable cardiac defibrillator (ICD) remain largely unknown within Europe.

AIMS

This study explored the nature of partner's experiences from the pre-ICD implantation phase up until a maximum of 20 months at home.

METHODS

Eight partners cohabiting with a recipient of an ICD were interviewed using a semistructured schedule. All interviews were transcribed and content analysed for emerging categories and themes.

FINDINGS

Four themes representing 11 categories conceptualised the partners' experiences, these included: Acknowledging the patient's need for the device, reactions to the device, safeguarding the patient, and returning to normality.

CONCLUSION

This qualitative study suggests that partners of ICD recipients progress through various difficult and adaptive stages when learning how best to support the patient. A point is reached when most are able to assume control and normalise their lives. This transformation is slow; however, to improve this process and empower partners, nurses should provide relevant information and include them in decisions affecting the patient. Further research into the unique needs of partners, which includes international perspectives, would be significant in developing practice and theory in this area.

A Review of Instruments on Cognitive Appraisal of Stress

PURPOSE

The purpose of this paper is to present a review of theoretically based measures of cognitive appraisal, and discuss psychometric strengths and limitations.

BACKGROUND

Understanding how an individual appraises stressful events becomes important when faced with alterations in mental health. Cognitive appraisals influence how an individual copes with stressful events and life crises that leads to changes in mental health. Measures on how an individual appraises a stressful event lack conceptual soundness and are limited by weak psychometric properties.

DATA SOURCES

Health and Psychosocial Instruments (HAPI) electronic database was searched using combinations of the key words cognitive appraisal, primary appraisal, secondary appraisal, appraisal of illness, appraisal of health, and stress appraisal. The quality of these instrument sources was assessed by published psychometric data in the primary source.

RESULTS

Five instruments were found that measure cognitive appraisal as theoretically described: the Meaning of Illness Questionnaire, the Stress Appraisal Measure, the Appraisal of Illness Scale, the Cognitive Appraisal of Health Scale, and the Primary Appraisal/Secondary Appraisal scale. A description of each tool, including purpose, scoring, and psychometric support, is provided.

CONCLUSION

There are a limited number of instruments that measure cognitive appraisal as theoretically described. Theoretically sound instruments with established psychometric support are needed to make accurate inferences about the role of cognitive appraisal in the mental and physical health of individuals experiencing stress.

When the Topic Turns to Sex: CASE SCENARIOS IN SEXUAL COUNSELING AND CARDIOVASCULAR DISEASE

Patients with cardiovascular disease and their partners frequently have concerns about sexual intimacy, and sexual counseling is needed across health care settings to ensure that patients receive information to safely resume sexual activity. The purpose of this review is to provide practical, evidence-based approaches to enable health care providers to discuss sexual counseling, illustrated by several case scenarios. Evidence shows that patients expect health care providers to initiate sexual activity discussions, although providers may be hesitant and often rely on patients to ask questions. Although some providers cite lack of knowledge or confidence in their ability to provide sexual counseling, others mention time pressures in the clinical setting. Although such barriers exist, sexual counseling can be individualized to the cardiac condition of a patient with a few select questions. The representative examples of patients with angina pectoris, myocardial infarction, coronary artery bypass surgery, heart failure, and implantable cardioverter defibrillator are used to illustrate key points and provide a model for sexual counseling in practice.

Psychological effects of implantable cardioverter defibrillator shocks. A review of study methods

Background: The implantable cardioverter defibrillator (ICD) saves lives but clinical experience suggests that it may have detrimental effects on mental health. The ICD shock has been largely blamed as the main offender but empirical evidence is not consistent, perhaps because of methodological differences across studies.

Objective: To appraise methodologies of studies that assessed the psychological effects of ICD shock and explore associations between methods and results.

Data Sources: A comprehensive search of English articles that were published between 1980 and 30 June 2013 was applied to the following electronic databases: PubMed, EMBASE, NHS HTA database, PsycINFO, Sciencedirect and CINAHL.

Review Methods: Only studies testing the effects of ICD shock on psychological and quality of life outcomes were included. Data were extracted according to a PICOS pre-defined sheet including methods and study quality indicators.

Results: Fifty-four observational studies and six randomized controlled trials met the inclusion criteria. Multiple differences in methods that were used to test the psychological effects of ICD shock were found across them. No significant association with results was observed.

Conclusions: Methodological heterogeneity of study methods is too wide and limits any quantitative attempt to account for the mixed findings. Well-built and standardized research is urgently needed.

Development and feasibility testing of decision support for patients who are candidates for a prophylactic implantable defibrillator: a study protocol for a pilot randomized controlled trial

BACKGROUND

Patients, identified to be at risk for but who have never experienced a potentially lethal cardiac arrhythmia, have the option of receiving an implantable cardioverter defibrillator (ICD) as prophylaxis against sudden cardiac death - a primary prevention indication. In Canada, there is no clear framework to support patients' decision-making for these devices. Decision support, using a decision aid, could moderate treatment-related uncertainty and prepare patients to make well-informed decisions. Patient decision aids provide information on treatment options, risks, and benefits, to help patients clarify their values for outcomes of treatment options. The objectives of this research are: 1) develop a decision aid, 2) evaluate the decision aid, and 3) determine the feasibility of conducting a trial.

METHODS/DESIGN

A development panel comprised of the core investigative team, health service researchers, decision science experts, cardiovascular healthcare practitioners, and ICD patient representatives will collaborate to provide input on the content and format of the aid. To generate probabilities to include in the aid, we will synthesize primary prevention ICD evidence. To obtain anonymous input about the facts and content, we will employ a modified Delphi process. To evaluate the draft decision aid will invite ICD patients and their families (n = 30) to rate its acceptability. After we evaluate the aid, to determine the feasibility, we will conduct a feasibility pilot randomized controlled trial (RCT) in new ICD candidates (n = 80). Participants will be randomized to receive a decision aid prior to specialist consultation versus usual care. Results from the pilot RCT will determine the feasibility of research processes; inform sample size calculation, measure decision quality (knowledge, values, decision conflict) and the influence of health related quality of life on decision-making.

DISCUSSION

Our study seeks to develop a decision aid, for patients offered their first ICD for prophylaxis against sudden cardiac death. This paper outlines the background and methods of a pilot randomized trial which will inform a larger multicenter trial. Ultimately, decision support prior to specialist consultation could enhance the decision-making process between patients, physicians, and families, associated with life-prolonging medical devices like the ICD.

Comparison of male and female psychological outcomes related to implantable cardioverter defibrillators (COMFORTID)

BACKGROUND

While randomised, controlled trials have established the efficacy of the implantable cardioverter defibrillator (ICD) for primary and secondary prevention of life threatening arrhythmias, psychosocial responses remain complex and poorly understood, especially across Europe. There appears to be a greater need to understand differences in the experience of men and women.

AIM

The aim of this prospective study was to explore differences in psychosocial adjustment over a 12 month period following ICD implantation.

METHODS

Fourteen female and thirty three male device recipients completed a series of questionnaires over a 12 month period. Instruments included a generic and an ICD specific Quality of Life (QOL) measure and the state-trait anxiety inventory.

RESULTS

Women reported higher levels of anxiety than men at discharge but over time demonstrated a significant improvement such that at 4, 8 and 12 months men were more anxious. Women reported significantly poorer emotional wellbeing at discharge, however by 12 months this was significantly improved with no difference in the perceptions held by men and women. Women consistently across the 12 months worried more than men about the impact of the device on appearance.

CONCLUSION

This study confirmed that most individuals adjust positively to the ICD during the first 12 months. Some gender differences in adjustment were evident. Further studies across Europe are warranted to establish gender specific interventions to support men and women as they adapt to life with ICD implants.

The prevalence of anxiety and depression in adults with implantable cardioverter defibrillators: a systematic review

OBJECTIVE

The implantable cardioverter defibrillator (ICD) is used to treat life-threatening ventricular arrhythmias and in the prevention of sudden cardiac death. A significant proportion of ICD patients experience psychological symptoms including anxiety, depression or both, which in turn can impact adjustment to the device. The objective of this systematic review was to assess the prevalence of anxiety and depression or symptoms of anxiety and depression among adults with ICDs.

METHODS

Search of MEDLINE®, CINAHL®, PsycINFO®, EMBASE® and Cochrane® for English-language articles published through 2009 that used validated diagnostic interviews to diagnose anxiety or depression or self-report questionnaires to assess symptoms of anxiety or depression in adults with an ICD.

RESULTS

Forty-five studies that assessed over 5000 patients were included. Between 11% and 28% of patients had a depressive disorder and 11-26% had an anxiety disorder in 3 small studies (Ns=35-90) that used validated diagnostic interviews. Rates of elevated symptoms of anxiety (8-63%) and depression (5-41%) based on self-report questionnaires ranged widely across studies and times of assessment. Evidence was inconsistent on rates pre- versus post-implantation, rates over time, rates for primary versus secondary prevention, and for shocked versus non-shocked patients.

CONCLUSION

Larger studies utilizing structured interviews are needed to determine the prevalence of anxiety and depression among ICD patients and factors that may influence rates of anxiety and depressive disorders. Based on existing data, it may be appropriate to assume a 20% prevalence rate for both depressive and anxiety disorders post-ICD implant, a rate similar to that in other cardiac populations.

A comparative study of uncertainty, optimism and anxiety in patients receiving their first implantable defibrillator for primary or secondary prevention of sudden cardiac death

BACKGROUND

Increasingly, patients are receiving implantable cardioverter defibrillators (ICDs) for prevention of sudden cardiac death. ICDs are implanted for primary prevention (patients at risk for ventricular arrhythmia [PP]) and secondary prevention (patients who have had/survived a sustained ventricular arrhythmia or cardiac arrest [SP]). Few prospective studies have examined psychosocial factors associated with these patients.

OBJECTIVES

To determine if patients receiving their first ICD for PP versus SP differed in uncertainty, anxiety, and optimism, before, 1 week, and 1 month after implant.

DESIGN

Prospective, descriptive, correlational pilot.

PARTICIPANTS AND SETTING

Fifteen PP and 15 SP patients receiving their first ICD were enrolled. Mean ages (+/- SD) were 65.7+/-11.3 and 67.9+/-7.7 respectively.

METHODS

Mishel's Uncertainty in Illness Scale (MUIS-C), State-Trait Anxiety Inventory (STAI) and the Life Orientation Test (LOT-R) were taken pre-implant, at the first post-implant visit, and at 1 month. Measures were compared using Student't-tests and ANOVA.

RESULTS

Pre-implant, both groups had moderately high MUIS-C scores (mean+/-SD; PP=67.67+/-13.36; SP=70.27+/-6.80; t=0.67; t(df)=28; p=0.507). LOT-R scores were 15.67+/-3.8 for PP and 16.47+/-3.6 for SP; t=0.59; t(df)=28; p=0.557. Pre-implant state anxiety scores were (mean PP=37.40+/-10.0, SP=37.73+/-13.6; t=0.076; t(df)=28; p=0.940). At 1-month PP patients had significantly lower uncertainty scores than the SP group (mean 62.33+/-4.17 versus 67.87+/-4.61; t=3.45; t(df)=28; p=0.002). A main effect for time, between pre-implant and 1-month, was found for uncertainty (F(2,56)=3.26; p<0.05) and state anxiety (F(2,56)=3.61, p<0.05), where both groups showed lower scores.

CONCLUSION

This study identified moderately high uncertainty in PP and SP patients prior to receiving their ICD. Though uncertainty was high, both groups reported an optimistic disposition and normal anxiety. At 1-month, SP patients had higher uncertainty scores than PP patients. This post-intervention uncertainty among patients who experienced an arrhythmic event warrants attention from nurses caring for ICD patients. Interventions to ameliorate uncertainty should be tailored to consider ICD indication.

Effect of a psychoeducational intervention on depression, anxiety, and health resource use in implantable cardioverter defibrillator patients

BACKGROUND

Psychological responses have been reported for some patients after the insertion of an implantable cardioverter defibrillator (ICD). This study tested the effects of a psychoeducational intervention on anxiety, depressive symptoms, functional status, and health resource use during the first year after ICD implantation.

METHODS

ICD patients (n = 246) were randomized to usual care (UC), group (GRP), or telephone counseling (TC) intervention that included education, symptom management, and coping skill training. Participants were 58 +/- 11 years, 73% men, and 23% minorities. Anxiety (State-Trait Anxiety Inventory [STAI]), depressive symptoms (Beck Depression Inventory II [BDI-II]), and functional status (Duke Activity Status Inventory [DASI]) were measured at baseline and after 1, 3, 6, and 12 months. Health resource use and disability days were tracked. Analyses were repeated-measures analysis of covariance to assess Group x Time effects,chi(2)for percentage with clinically significant anxiety and depression at each time point, and logistic regression.

RESULTS

All groups experienced decreased anxiety and depressive symptoms over the 12 months; GRP intervention had lower STAI (P = 0.03) than UC at 3 months. Logistic regression revealed group differences for predicted probability of having depressive symptoms at 12 months (UC = 0.31, GRP = 0.17, TC = 0.13, P = 0.03). UC had greater calls to providers at 1 and 6 months (P < 0.05) and more sick/disability days at 12 months (P = 0.01) than intervention groups.

CONCLUSIONS

A psychoeducational intervention reduced anxiety and depressive symptoms early after ICD implant, lowered probability of depressive symptoms at 1 year, and decreased disability days/calls to providers. These findings support further study and clinical use of both group and telephone interventions to yield better psychological outcomes after ICD implant.

The experiences and concerns of young adults (18-40 years) living with an implanted cardioverter defibrillator (ICD)

BACKGROUND

Although the implanted cardioverter defibrillator (ICD) is a widely accepted life-saving technology, adjusting to life after ICD implantation may vary according to the recipient's age. Few studies have investigated how young adults manage life with an ICD and there are no studies describing their concerns or experiences of living with an ICD.

AIM

The aim of the study was to describe the experiences and concerns of young adults (18-40 years) living with an ICD.

METHODS

Qualitative descriptive methodology was chosen incorporating interviews and written narrative responses to investigate twenty young adult's experiences of living with an ICD.

RESULTS

There were four descriptive categories: psychosocial, developmental, physical, and economical. Themes in the psychosocial category were: returning to normal, mood disturbances, and body image concerns. Themes in the developmental category were unique to young adults: childbearing and childrearing, while themes in the physical category were expectation regarding physical activity, and the economical category, the issue of financial security.

CONCLUSIONS

These data reveal that young adults with ICDs experience the unique concerns of childbearing, childrearing, and are worried about their financial security. These findings provide insight for the development of age-appropriate interventions for young adults before and after ICD implantation.

Changes in psychosocial distress in outpatients with heart failure with implantable cardioverter defibrillators

Patients given implantable cardioverter defibrillators (ICDs) after arrhythmic events or sudden cardiac arrest (SCA) experience psychosocial distress. ICDs now are inserted for the primary prevention of SCA in patients with heart failure; the psychosocial impact of ICDs on patients with heart failure is unknown. Changes in psychosocial status in these ICD recipients were examined. ICD recipients (n = 57) completed depression, anxiety, and social support inventories every 6 months for up to 2 years. Initially, 35% of recipients were depressed and 45% of recipients were anxious. In linear mixed models, depression decreased over time overall but increased in those who experienced ICD shocks. Anxiety decreased in New York Heart Association class III ICD recipients but not in class II ICD recipients. Decreases in social support were related to age: the younger the patient the greater the decrease. A significant proportion of ICD recipients were depressed or anxious, or had diminished social support even after 2 years. Investigation of strategies to improve ICD recipients' psychosocial status is warranted.

Partner quality of life in the antiarrhythmics versus implantable defibrillators trial

BACKGROUND AND OBJECTIVE

The quality of life (QOL) of patients with ventricular dysrhythmias is well studied, but less is known about the QOL of their partners. This study describes the QOL of partners of patients with serious ventricular dysrhythmias enrolled in the Antiarrhythmics Versus Implantable Defibrillators trial.

SUBJECTS AND METHODS

A convenience sample of 124 partners of patients randomized to antiarrhythmic drugs (n = 59) or an implantable cardioverter defibrillator (n = 65) in the Antiarrhythmics versus Implantable Defibrillators trial was obtained. The Short Form-36 and Quality of Life Index were assessed at baseline (postrandomization) and at 3-, 6-, and 12-month follow-up.

RESULTS AND CONCLUSIONS

The mean age of the partners was 62 years. Most were white and female. Their mean Short Form-36 scores were comparable to a normative age group. Partner and participant mean Short Form-36 and Quality of Life Index scores correlated modestly (range 0.25-0.36). The physical summary scores of partners using the Short Form-36 declined over time, whereas their mental summary scores remained stable. Partner concerns related to death, dysrhythmia recurrence, and the impact of dysrhythmias on enjoyment of life lessened from baseline to 12 months. Concern about implantable cardioverter defibrillator function remained stable over time. Although the sample size of this study was relatively small and limited by missing data for some assessments, it is the largest prospective study of QOL in partners of patients with serious dysrhythmias. The results offer a foundation for future research of the partners of patients with serious dysrhythmias in terms of identifying their needs, offering support, and maximizing QOL.

Depressive coping is a predictor for emotional distress and poor quality of life in a German-Austrian sample of cardioverter-defibrillator implant recipients at 3 months and 1 year after implantation

OBJECTIVE

The implantable cardioverter defibrillator (ICD) has been proven to prolong the lives of patients with life-threatening ventricular arrhythmia. However, implant recipients must cope with numerous challenges. We studied the effects of specific coping strategies and the adaptability of coping in ICD implant recipients.

METHOD

This prospective study investigated the subjective well-being and objective disease course in 180 patients with life-threatening cardiac arrhythmias, who were recruited while awaiting implantation of a cardioverter defibrillator. Patients completed well-validated self-assessment questionnaires before implantation (T0), as well as 3 months (T1) and 1 year (T2) after implantation. In addition, cardiological findings were documented.

RESULTS

Depressive coping (range Beta, -0.36 to -0.58) was found to be a stable highly-significant predictor for low emotional well-being and quality of life. Active problem-oriented coping showed small positive influence (range Beta, 0.10 to 0.19). Employing a broad range of coping strategies was predictive of less emotional distress and better quality of life.

CONCLUSIONS

Depressive coping is a risk factor for emotional distress and poor quality of life after ICD implantation. Patients with this tendency should be identified early and offered supportive psychotherapy.

Depression and anxiety status of patients with implantable cardioverter defibrillator and precipitating factors

BACKGROUND

Implantable cardioverter defibrillators (ICDs) are life-saving devices in treatment of life-threatening arrhythmia. We evaluate the emotional status of Turkish patients with ICD and try to explain factors that affect emotional status of the patients.

METHODS

Ninety-one patients with previously implanted ICD were included in the study. Follow-up periods, presence of ICD shock, shock frequency, time of the recent shock, age, and gender were noted. Depression and anxiety scores were evaluated according to Hospital Anxiety and Depression (HAD) chart.

RESULTS

Mean anxiety and depression scores were found as 9.1 +/- 5.3 and 7.2 +/- 5.1, respectively. According to HAD charts, 42 patients (46%) had anxiety and 37 patients (41%) had depression. Depression scores indicated significant difference between subgroups divided on the basis of follow-up periods (P = 0.026) and on the basis of time of recent shock (P = 0.028). There was significant difference in anxiety scores (P = 0.016) between patients with ICD shocks and patients with no shocks. When the patients were divided into subgroups according to shock frequency, both depression (P = 0.024) and anxiety (P = 0.016) scores presented significant difference. In female patients, depression and anxiety scores were found significantly higher compared to male patients (P = 0.046 and P = 0.016, respectively). In multivariate analysis, gender and shock frequency were found as predictors for anxiety scores (P = 0.019 and P = 0.044, respectively). However same analysis revealed no predictive factor for depression score.

CONCLUSION

Our study indicates presence of depression and anxiety in nearly half of the patients with ICD. Consultation with psychiatry should be a part of the treatment for patients with ICD, especially for those who constitute high-risk groups.

Gender differences in implantable cardioverter-defibrillator patients at the time of insertion

Gender differences in physical and psychological health and responses in persons receiving implantable cardioverter-defibrillators (ICDs) have been reported but are not well delineated. This study examined symptoms of pain and sleep difficulties, functional status, and psychological responses in 180 (75%) men and 60 (25%) women before and immediately following their first ICD implantation. Women were significantly younger, less likely to be married, and had less history of coronary artery disease than men. Forty-eight percent of women were New York Heart Association class III-IV vs. 27% of men (p<0.05). Women had lower functional status and were more likely to report symptoms of increased pain severity and sleep difficulties. Differences in functional status and pain were reduced after adjusting for New York Heart Association class and age, respectively. There were no differences in depressive symptoms or anxiety. Clinical implications of gender-related responses include the need to address symptoms of heart failure as well as increased pain and sleep difficulties in women at the time surrounding ICD implantation. Longitudinal studies and gender-focused nursing interventions should be developed to promote better understanding of responses and to improve recovery outcomes for ICD patients.

A CNS-facilitated ICD support group: a clinical project evaluation

PURPOSE

The purpose of this article is to describe and evaluate a clinical nurse specialist (CNS)-facilitated support group for recipients of implantable cardioverter defibrillator. Specific evaluation aims were as follows: (1) How do demographic and clinical factors differ between those who attended the support group and those who did not? (2) Is there a difference in the quality of life index (QLI) of individuals with an implantable cardioverter defibrillator who attended the CNS-facilitated support group and those who did not? (3) What demographic and clinical factors are related to QLI?

DESIGN AND METHOD

Clinical project theory-based objectives were described. Implementation of the project was evaluated by retrospective survey of all implantable cardioverter defibrillator recipients during a 10-year time frame using the Ferrans and Powers' Quality of Life Index: Cardiac Version and demographic questionnaire. Attendance sheets defined who attended so comparisons could be made.

EVALUATION RESULTS

One hundred and twelve surveys were returned (34% return rate). A positive relationship between CNS visit during hospitalization, number of and value of supports, years of education, and ejection fraction was noted with attendance at the support group. No between-group differences on total QLI, or on any subscales, were found. Comorbidity was the only clinical factor correlated with QLI.

CONCLUSION

CNS-facilitated support groups can be offered as an additional support. Evaluation design issues limited the measuring outcomes of existing interventions. Future prospective studies are recommended to determine the affect of the support group on quality of life.

Perceived threat in compliance and adherence research

Within the broader agenda of adherence research, health beliefs have been identified as being significant predictors of adherence. Specifically, perceived threat as a health belief has received considerable attention in compliance and adherence research from multiple perspectives in multiple patient populations. The purpose of this paper is to analyze the concept of perceived threat as it relates to treatment adherence through a series of perspectives: conceptual, methodological, and empirical. Analysis of the literature reveals that there is lack of consistency in operationalization of perceived threat as it relates to treatment adherence. Perceived threat is most commonly cited in studies that focus on health beliefs or utilize a stress and coping paradigm. Instruments have been developed with items that measure perceived threat. Measures of threat occur primarily through uni-dimensional measures that do not reflect the inter-relatedness of the threat experience to personal and contextual factors. Future research examining perceived threat from a cognitive appraisal perspective, where both primary and secondary appraisals can be examined, may provide additional insight into factors affecting treatment adherence.

Sexual concerns and educational needs after an implantable cardioverter defibrillator

BACKGROUND

Patients with an implantable cardioverter defibrillator (ICD) describe anxiety, fears, and other psychosocial issues, although sexual concerns are not well understood.

PURPOSE

The purpose of this descriptive study was to explore the experiences of patients and partners with return to sexual activity post-ICD implantation.

PARTICIPANTS

Subjects were 12 patients with an ICD (10 men, 2 women) and 4 partners (1 man, 3 women). Most patients with an ICD and partners were age 55 years or older, with a mean age of 62 years for patients and 47 years for partners.

METHODS

A semistructured interview was used to explore the meaning and influence of the ICD on the sexual relationship. Interviews were recorded, transcribed verbatim, and analyzed using a qualitative descriptive approach.

RESULTS

Themes identified were (1) anxiety and apprehension, with subthemes of partner overprotectiveness and fear of ICD discharge with sexual activity; (2) varying interest and pattern of sexual activity; (3) powerfulness of ICD discharge; and (4) a need for information and sexual counseling.

IMPLICATIONS

Additional research is needed to further understand the experience of ICD discharge with sexual activity and to develop educational strategies.

Quality of life in implanted cardioverter defibrillator recipients: the impact of a device shock

BACKGROUND

The success of the implanted cardioverter defibrillator (ICD) in prolonging the life of patients with arrhythmia suggests a need to assess quality of life (QOL), especially in those who receive an ICD shock.

OBJECTIVES

The purpose of this study was to compare QOL in a group who received an ICD shock with a group who did not receive an ICD shock during the first year.

METHODS

Fifty-nine subjects, 42 men and 17 women with a mean age 63 years, completed the Medical Outcomes Study Short Form-36, Ferrans and Powers QOL Index, Profile of Mood States at implantation and 1 year, and the Brodsky ICD Questionnaire at 1 year.

RESULTS

Thirty-seven percent received an ICD shock. Those in the shock group had worse mental health ( P < or = .04) and vitality scores ( P < or = .03) on the Short Form-36, increased anxiety ( P < or = .015), fatigue ( P < or = .005), and psychologic distress ( P < or = .02), as measured by Profile of Mood States, compared with the no shock group at 1 year.

CONCLUSIONS

Shocked ICD recipients demonstrate mental health concerns.

Psychosocial Issues of Patients With Implantable Cardioverter Defibrillators

Use of implantable cardioverter defibrillators has become standard therapy for patients at high risk for life-threatening ventricular arrhythmias. Although acceptance of the device is generally high among patients and their families, quality of life and psychosocial issues associated with use of the defibrillators deserve greater attention to improve outcomes. Psychosocial issues, their ramifications, and theory-and evidence-based approaches to improving outcomes are described.

Ventricular Dysrhythmias

Cardiovascular nurses contribute significantly to health outcomes and frequently assume responsibility for the clinical and organizational processes to ensure positive outcomes for patients and families. In ventricular dysrhythmia populations, nurses have provided evidence for practices that influence outcomes and have studied patient outcomes related to mortality, morbidity, quality of life, psychological and physical functioning, symptoms, and family responses. Additionally, nurses have contributed to understanding organizational outcomes, such as costs and resource use related to patients with dysrhythmias. Most ventricular dysrhythmia outcome studies are descriptive. More intervention research is needed to develop a cohesive and comprehensive body of evidence upon which to base dysrhythmia nursing care to improve patient outcomes.

Can nurses in cardiology areas prepare patients for implantable cardioverter defibrillator implant and life at home?

This study explored nurses' confidence and competence in preparing patients for having an implantable cardioverter defibrillator implanted and for life at home after discharge. Whilst research has identified various physical and psychosocial effects to patients and their partners associated with device implant and subsequent lifestyle adjustments, no research has explored nurses' knowledge of the device or these effects. A survey was designed using a purposive sample of 152 nurses from cardiology areas in four large teaching hospitals and a 28-point postal questionnaire to explore knowledge of the device and its impact. Most subjects were not confident in their abilities to prepare patients for implant or life at home after implant. Knowledge of the device and its effects appeared poorly understood by all nurses, irrespective of additional qualifications, length of time since qualifying or area of work. Many participants were aware of the poor knowledge level of nurses and identified it as a weakness in current care practices. Lack of understanding may impair preparation of patients for implantation of or for living with an implantable cardioverter defibrillator, and feasible strategies to change this situation will require careful consideration and further investment.

Patient experiences with atrial fibrillation and treatment with implantable atrial defibrillation therapy

BACKGROUND

Patient perspectives about their illness experiences, symptoms, and treatment are essential aspects of quality of life and provide direction for patient and provider decision making regarding innovative therapies such as implantable devices for arrhythmia.

PURPOSE

The purpose of this qualitative study was to describe: 1) the experience of patients living with symptomatic, drug-refractory atrial fibrillation (AF) and 2) patient experiences and acceptance of treatment with the implantable cardioverter defibrillator (ICD) with atrial therapies (ICD-AT) including ventricular and atrial defibrillation therapy.

PARTICIPANTS

Subjects were 3 women and 8 men, 35 to 80 years of age, who received the Medtronic Jewel AF 7250 ICD-AT as therapy for recurrent, drug-refractory AF, had a history of AF for 3 to 20 years and had experienced multiple treatment modalities including frequent external cardioversion in an effort to control their AF.

METHODS

A semi-structured interview addressed experiences of symptoms and prior treatment for AF and experiences, concerns, and perceived benefits of the ICD-AT. Interviews were recorded and transcribed verbatim. Narratives were coded and categorized using Atlas Ti(R) software. Qualitative interpretive analysis methods were used to identify key themes.

RESULTS

Before ICD-AT, patient themes focused on AF that was: 1) misdiagnosed, minimized, and poorly treated; 2) distressful because of frequent and intense AF symptoms (fatigue, dizziness, shortness of breath, and anxiety) before ICD-AT; 3) limiting of activities of daily living; 4) associated with distress from enduring previous treatment; and 5) associated with the continuous pursuit of successful treatment and maintenance of normalcy. Decision making regarding ICD-AT therapy included weighing symptom or treatment distress versus anticipated risks or benefits, hope for better outcomes, and lack of options. After ICD-AT, themes included positive perceptions of the device because of AF symptom relief, ability to resume normalcy, and medication tolerance; incorporation of shock experiences into life routines; and patient suggestions regarding preparation and social support.

IMPLICATIONS

Symptoms of AF have a major negative impact on overall quality of life. Treatment with the ICD-AT confers a sense of security and reduced symptom distress. Greater provider attention to patient preparation and facilitating social support are important for future ICD-AT patient care.

Psychological therapies for recipients of implantable cardioverter defibrillators

Implantable Cardioverter Defibrillators (ICDs) are an increasingly common therapy for the treatment of ventricular arrhythmias. Whereas most ICD recipients adjust well to living with the implant, a substantial minority suffer anxiety, depression, and anger that appears to be related to the ICD. A large number of studies have reported on the incidence of psychopathology and common psychosocial problems among patients with ICDs, however very few psychological interventions with this cohort have been reported. In an extensive literature search we identified only a handful of studies that described outcomes of psychological interventions, and most of these were in pilot form. Only one randomized controlled study with a homogenous sample of ICD patients has been reported to date. Given the unique situation of patients with ICDs and the particular vulnerability of those who experience frequent shocks, the evaluation of interventions that may improve psychological adjustment within this group would appear a worthwhile endeavor.

Sexual concerns of patients and partners after an implantable cardioverter defibrillator

Sexual concerns of patients after an implantable cardioverter defibrillator (ICD) exist, but are not well understood. This study explored sexual concerns and educational needs of those living with an ICD and their partners. Study results suggest a need for written patient education tools specific to sexual issues for patients and partners, and educational resources for health professionals. Addressing the fears and concerns related to sexual function of ICD patients and partners is an essential aspect of rehabilitation and recovery.

A new foundation for methodological triangulation

PURPOSE

To show how triangulation with qualitative and quantitative methods can help confirm a theory to a greater degree than can either method alone. CONSTRUCT: Coherence view of theory structure and confirmation. Evidence helps confirm a theory if the theory is the most coherent way of accounting for the evidence, and one theory is more coherent than another insofar as it leaves fewer unanswered questions (and fewer unquestioned answers).

METHODS

The method of this theoretical essay is analytic. Analysis of the debate over methodological triangulation reveals presuppositions about theory structure and confirmation. Well-known arguments in the philosophy of science are presented to show that the presuppositions are false. The arguments provide evidence for the construction of an alternative, coherence model of theory structure and confirmation.

FINDINGS

Three consequences of the analysis are: (a) qualitative and quantitative methods do not produce theories with different structures; (b) qualitative and quantitative methods help to confirm theory in the same ways; and (c) used together, qualitative and quantitative methods can confirm a theory to a greater degree than the use of either method alone.

CONCLUSIONS AND IMPLICATIONS

A coherence of model of theory structure and confirmation supports a version of the blending view of methodological triangulation. Triangulation can provide completeness, abductive inspiration, and confirmation. This version of blending provides principles for resolving issues of methodological dominance and order, and it indicates how different methods can disconfirm theory.

Redefining life while forestalling death: living with an implantable cardioverter defibrillator after a sudden cardiac death experience

Secondary analysis is a resourceful approach for making further use of existing data sets to answer questions not previously addressed or to expand on content not specifically examined in the original study. Using Heideggerian hermeneutics, the author analyzed transcripts of the stories of individuals with implantable cardioverter defibrillators (ICD) from three of her earlier phenomenological studies to obtain a description of the experience of living with an ICD after a sudden cardiac death experience. Three related themes emerged: (a) losing control: technology as lifesaving yet changing everything; (b) getting on with living: regaining control or conditional acceptance; and (c) creating a new vision: transformation or tenuous truce. The constitutive pattern was redefining life while forestalling death.

Classic conditioning and dysfunctional cognitions in patients with panic disorder and agoraphobia treated with an implantable cardioverter/defibrillator

OBJECTIVE

A model for the development of anxiety disorders (panic disorder with or without agoraphobia) is needed. Patients with an implantable cardioverter/defibrillator (ICD) are exposed to repeated electric shocks. If the theory of anxiety development by aversive classic conditioning processes is valid, these repeated shocks should lead to an increased risk of anxiety disorders. To study this hypothesis, we retrospectively studied 72 patients after implantation of an automatic ICD.

METHODS

Patients were assessed with the semistructured Diagnostic Interview of Psychiatric Disease 1 to 6 years after implantation of an automatic ICD. Panic disorder and/or agoraphobia was diagnosed in patients who fulfilled all DSM-III-R criteria for those conditions.

RESULTS

Anxiety disorder developed in 15.9% of patients after ICD implantation. This was significantly related to the frequency of repeated defibrillation (shocks) to stop malignant ventricular arrhythmias. Dysfunctional cognitions are an additional vulnerability factor.

CONCLUSIONS

The data support both the conditioning hypothesis and the cognitive model of anxiety development. These findings suggest that ICD patients are an appropriate risk population for a prospective study of the development of anxiety disorders.

Living with an implantable cardioverter-defibrillator: a review of the current literature related to psychosocial factors

Sudden cardiac death (SCD) is responsible for 300,000 deaths annually. Lethal ventricular dysrhythmias account for the majority of SCDs. Implantable cardioverter-defibrillators (ICDs) are the emerging treatment for lethal dysrhythmias. Although reductions in SCD mortality with ICDs are clear, the psychologic and social consequences of these devices reveal a mixed success. Patients with ICDs have high levels of anxiety and depressive symptoms. Conversely, most studies of quality of life in patients with ICDs report that the device is well accepted despite fears of being shocked. The ICD shocks are a unique aspect of treatment and have the potential to cause psychologic distress. Nursing needs to provide care from a holistic perspective. Support groups provide reassurance and allow patients to discuss expectations and fears related to the ICD. Research needs to be conducted to explore the impact of these devices on the lives of patients and their families.
