Periprocedural complications of cardiac implantable electronic device implantation in very elderly patients with cognitive impairment: A prospective study

Very elderly people (over 80 years) with cardiac implantable electronic devices (CIEDs) indications often have a higher prevalence of aging comorbidity, among which cognitive impairment is not uncommon. This study aimed to investigate periprocedural complications of CIED implantation among very elderly patients with and without cognitive impairment. One hundred eighty patients ≥80 years of age indicated for CIED implantation were included in our study. During hospitalization, the cognitive evaluation was performed according to the Diagnostic and Statistical Manual of Mental Disorders (fifth edition). According to the cognitive test results, patients were divided into 2 groups (90 patients with normal cognitive function and 90 patients with cognitive impairment). Meanwhile, their physical parameters and laboratory measurements were completed. The procedural data and periprocedural complications were collected from both groups. The association between cognitive impairment and periprocedural complications was analyzed using univariate and multiple logistic regression analyses. During a one-month follow-up, the most frequent periprocedural complications in very elderly patients were pocket hematoma and thrombosis events. Cognitively impaired patients had a higher incidence of complications than normal cognitive patients. Multivariate regression analysis showed that cognitive impairment was positively correlated with periprocedural complications in very elderly patients. Cognitive impairment is associated with increased periprocedural complications of CIED implantation in very elderly patients.

The Effect of Religious Intervention Using Prayer for Quality of Life and Psychological Status of Patients with Permanent Pacemaker

The development of heart disease, followed by the pacemaker implantation, has reduced the quality and psychological problems for patients. Thus, the present study was conducted to determine the effect of prayer on the quality of life and the psychological status of patients with permanent pacemaker. This is a quasi-experimental study in which 75 patients were assigned to experimental and control groups. Religious intervention was conducted for the experimental group, including the Tavasol prayer and four recommended (mustahab) remembrances in 7 sessions. Before and after the intervention, the patients were provided with the quality of life questionnaire and psychological status. Then, the questionnaires were analyzed using descriptive and analytical tests. Before intervention, there was no difference between quality of life status and psychological status of patients, but after intervention, their quality of life increased and their psychological status improved significantly. The implementation of religious intervention based on prayer positively affects the quality of life and psychological status of patients; thus, implementing this intervention is necessary for patients.

The influence of age on the psychological profile of patients with cardiac implantable electronic devices: results from the Italian population in a multicenter study conducted by the European Heart Rhythm Association

BACKGROUND

Cardiac implantable electronic devices (CIEDs) are widely used to treat bradyarrhythmias or improve the prognosis of patients with heart failure (HF).

AIMS

To evaluate age-related (≤ 75 vs. > 75 years) attitudes, worries, psychological effects and needs in an Italian CIEDs population.

METHODS

Patients attending their periodical ambulatory evaluation received a questionnaire conceived by the European Heart Rhythm Association Scientific Initiatives Committee as part of a multicenter, multinational snapshot survey. Seven countries participated in the study, and 1646 replies were collected. Of these, 437 (27%) were from Italy. Present results refer to the Italian population only. CIEDs were stratified into devices to treat bradycardia or HF.

RESULTS

The use of CIEDs was more common in advanced age. Older patients needed less information about CIEDs than younger ones (p = 0.044), who would prefer to be better informed about CIEDs-related consequences on psychologic profile (p = 0.045), physical (p < 0.001) and sexual (p < 0.001) activities, and driving limitations (p = 0.003). When compared to older subjects, younger individuals experienced more difficulties (p = 0.035), especially in their professional (p < 0.001) and private life (p = 0.033), feeling their existence was limited by the device (p < 0.001). Conversely, quality of life (HRQL) more often improved in the elderly (p = 0.001). Information about what to do with CIEDs at the end of life is scant independently of age.

CONCLUSIONS

HRQL after CIEDs implantation improves more frequently in older patients, while the psychological burden of CIEDs is usually higher in younger patients. End of life issues are seldom discussed.

Patients' experiences of remote communication after pacemaker implant: The NORDLAND study

BACKGROUND

The concept of 'patient experience' has become central to how to improve healthcare. Remote communication with patients is today a frequent practice in healthcare services, showing similar outcomes to standard outpatient care while enabling cost reduction in both formal and informal care. The purpose of this study was to analyse the experiences of people with telemonitoring pacemakers.

METHODS

Patients were randomly allocated to either the telemonitoring or hospital monitoring follow-ups. Using the 'Generic Short Patient Experiences Questionnaire' (GS-PEQ), as well as an ad-hoc survey from the 'telehealth patient satisfaction survey' and 'costs survey', patients' experiences were measured six months after the pacemaker implant in a cohort of 50 consecutive patients. The mean age was 74.8 (± 11.75) years and 26 (52%) patients were male of which 1 was lost in follow-up. Finally, 24 patients were followed up with standard hospital monitoring, while 25 used the telemonitoring system. Differences in baseline characteristics between groups were not found.

RESULTS

Findings showed overall positive and similar experiences in patients living with telemonitoring and hospital monitoring pacemakers. Significant differences were found in GS-PEQ concerning how telemonitoring patients received less information about their diagnosis/afflictions (p = 0.046). We did not find significant differences in other items such as 'confidence in the clinicians' professional skills', 'treatment perception adapted to their situation', 'involvement in decisions regarding the treatment', 'perception of hospital organisation', 'waiting before admission', 'satisfaction of help and treatment received', 'benefit received', and 'incorrect treatment'.

CONCLUSIONS

The remote communication of pacemakers was met with positive levels of patients' experiences similarly to patients in the hospital monitoring follow-up. However, telemonitoring patients received less information. Thus, improving the quality and timing of information is required in telemonitoring patients in the planning and organisation of future remote communication healthcare services for people living with a pacemaker implant.

Hybrid bodies and the materiality of everyday life: how people living with pacemakers and defibrillators reinvent everyday routines and intimate relations

Technologies inside bodies pose new challenges in a technological culture. For people with pacemakers and defibrillators, activities such as passing security controls at airports, using electromagnetic machines, electrical domestic appliances and electronic devices, and even intimate contacts with their loved ones can turn into events where the proper functioning of their device may be at risk. Anticipation of potentially harmful events and situations thus becomes an important part of the choreography of everyday life. Technologies inside bodies not only pose a challenge for patients living with these devices but also to theorising body-technology relations. Whereas researchers usually address the merging of bodies and technologies, implants ask us to do the opposite as well. How are we to understand human-technology relations in which technologies should not entangle with bodies because they serve other purposes? Based on a study of the daily life practices of people with pacemakers and defibrillators in the Netherlands and the US, I argue that disentanglement work, i.e. work involved to prevent entanglements with objects and people that may inflict harm upon implanted devices, is key to understanding how hybrid bodies can survive in today's densely populated technological landscape.

Validity and Reliability of the Indonesian Version of SF-36 Quality of Life Questionnaire on Patients with Permanent Pacemakers

AIM

to construct and validate Indonesian version of SF-36.

METHODS

this is a cross-sectional study, which consist of 2 stages process: 1) language and cultural adaption; and 2) validity and reliability evaluation. We evaluated 32 pacemaker patients during language and cultural adaptation stage and 20 pacemaker patients during validity and reliability evaluation stages from September 2014 to August 2015. We followed cross-cultural adaptation guideline to produce Indonesian version of the questionnaire. The final translated questionnaire was checked by assessing the correlation of SF-36 and 6-minutes walking test (6MWT) and NT pro-BNP result.

RESULTS

Indonesian version of SF-36 showed positive correlation between 6MWT result and physical functioning (PF) (r=0.363; p=0.001) and negative correlation between NT pro-BNP score with general health (GH) (r=-0.269; p=0.020) and mental health (MH) (r=-0.271; p=0.019). The internal consistency of Indonesian version of SF-36 questionnaire, which measured by Cronbach's alpha, was good with value of >0.70. Repeatability between day 1 and day 8 was good, with strong positive correlation (r=0.626; p=0.003).

CONCLUSION

the Indonesian version of SF-36 could be used as a general questionnaire to assess quality of life in patients with permanent pacemaker.

Sustaining cyborgs: sensing and tuning agencies of pacemakers and implantable cardioverter defibrillators

Recently there has been a renewed interest in cyborgs, and particularly in new and emerging fusions of humans and technologies related to the development of human enhancement technologies. These studies reflect a trend to follow new and emerging technologies. In this article, I argue that it is important to study 'older' and more familiar cyborgs as well. Studying 'the old' is important because it enables us to recognize hybrids' embodied experiences. This article addresses two of these older hybrids: pacemakers and implantable cardioverter defibrillators inserted in the bodies of people suffering from heart-rhythm disturbances. My concern with hybrid bodies is that internal devices seem to present a complex and neglected case if we wish to understand human agency. Their 'users' seem to be passive because they cannot exert any direct control over the working of their devices. Technologies inside bodies challenge a longstanding tradition of theorizing human-technology relations only in terms of technologies external to the body. Cyborg theory is problematic as well because most studies tend to conceptualize the cyborg merely as a discursive entity and silence the voices of people living as cyborgs. Inspired by feminist research that foregrounds the materiality of the lived and intimate relations between bodies and technologies, I argue that creating these intimate relations requires patients' active involvement in sustaining their hybrid bodies. Based on observations of these monitoring practices in a Dutch hospital and interviews with patients and technicians, the article shows that heart cyborgs are far from passive. On the contrary, their unique experience in sensing the entangled agencies of technologies and their own heart plays a crucial role in sustaining their hybrid bodies.

[Comorbid anxiety disorders and quality of life in patients with an artificial cardiac pacemaker]

AIM

To investigate correlations between anxiety disorders, quality of life (QoL) and patient's age, mode, duration and course of cardiac pacing (CP).

MATERIAL AND METHODS

Examination covered 134 patients (75 females and 59 males) with artificial pacemaker (APM). It included psychological testing with Hospital Anxiety and Depression Scale (HADS), QoL study with questionnaire MOS-SF-36.

RESULTS

APM implantation caused anxiety disorders in 80.6% patients, 51.5% had clinical symptoms of anxiety. An physiological and frequency-adaptive modes of PC, at the age under 50, in the absence of ECS complications frequency and severity of anxiety disorders are the lowest. Staged changes in the course of anxiety disorders were seen after primary APM implantation and in uncomplicated PC. APM implantation, irrespective of PC mode, significantly increased physical and mental parameters of QoL in patients under 50 years of age as well as mental health parameters in patients over 70.

CONCLUSION

It is necessary to conduct psychological testing in APM patients and their psychic rehabilitation for improvement of QoL.

Quality of life and psychological well-being in patients with various pacing modes

AIM

of the study was to assess the influence of different pacing modes on the quality of life (QOL), anxiety and depression.

METHODS

QOL was assessed in 101 patients (58 men, mean age 69.39 +/- 14.64 years) with implanted pacemaker (35 patients received VVI pacemaker, 17 patients VVIR, 21 patients DDD, 28 patients DDDR). QOL was measured by the SF-36 and Aquarel questionnaires, anxiety by Beck scale and depression by Zung scale.

RESULTS

No differences in QOL were observed between patients with single chamber and dual chamber pacing. Patients with rate-adaptive pacing had higher scores in SF 36 scales (physical component summary, mental component summary, vitality and bodily pain), Aquarel (chest pain and dyspnea) and they exhibited lower degree of anxiety and depression compared to non-rate-adaptive pacing. Differences were shown only in a group of dual chamber pacemakers, not in the group of single chamber pacemakers. There was a strong correlation between the degree of anxiety and depression and the QOL in pacemaker patients.

CONCLUSION

Dual chamber rate-adaptive pacing offered better QOL and psychological profile compared to dual chamber non-rate-adaptive pacing. No differences were observed between single chamber and dual chamber pacing (Tab. 3, Fig. 3, Ref. 24).

Pacing for neurally mediated syncope: is placebo powerless?

BACKGROUND

After two recent controlled trials failed to prove superiority of cardiac pacing over placebo in patients affected by neurally mediated syncope, a widely accepted opinion is that cardiac pacing therapy is not very effective and that a strong placebo effect exists.

AIM

To measure the effect of placebo pacing therapy.

METHOD AND RESULTS

We compared the recurrence rate of syncope during placebo vs. no treatment in controlled trials of drug or pacing therapy. Syncope recurred in 38% of 252 patients randomized to placebo pooled from five trials vs. 34% of 881 patients randomized to no treatment pooled from eight trials. The corresponding recurrence rate with active cardiac pacing was 15% in 203 patients from six trials.

CONCLUSIONS

Placebo is not an effective therapy for neurally mediated syncope. Different selection criteria in patients who are candidates for cardiac pacing-for example, presence, absence, or severity of the cardioinhibitory reflex may separate positive from negative trials.

La adjudicación de recursos en los pacientes con mal pronóstico: la necesidad de un debate

OBJECTIVE

Assess the opinion of health care professions on the awarding of resources when the patient has a bad prognosis.

DESIGN

Survey type test where a scenario of a patient with a 6 month life prognosis is posed, differentiating between good and bad quality of life. It is evaluated if the following resources would be indicated if necessary: admission to ICU, hemodialysis, hip prosthesis, transplant, Hospital admission, antibiotics for bacterial infection, permanent pacemaker and surgery. To analyze the possible association between the variables, the Pearson's Chi Square Test or that of linear tendency was used. To determine if each person interviewed was appropriate in a different way based on the patient's quality of life status, the McNemar test was used.

SETTING

University Hospital of 480 beds.

PARTICIPANTS

Sample of 256 volunteers (physicians and nurses) from the Emergency Service, Intensive Care Unit and Operating Room.

INTERVENTIONS

A responsible physician was in charge of personally distributing the survey during a 2-week period and to explain the possible doubts that could arise on it.

RESULTS

A total of 23.8% of those surveyed considered that transplant would be indicated and 79.8% that permanent pacemaker would be indicated if the patient had a good quality of life. If there was bad quality of life, 9.1% would have always indicated hemodialysis (60.5% never), 2.8% hip prosthesis (81.1% never) and 4% complex surgery (78.8% never). There were also significant differences in all the variables studied, depending on whether the patient had good or bad quality of life.

CONCLUSION

There is great variability on the allotment of resources for patients with limited possibilities of survival.

Effects of a self-care program on the health-related quality of life of pacemaker patients: a nursing intervention study

An experimental, multi-centre, randomized study with a nurse-led intervention was conducted with the aim of evaluating the effects on HRQoL of a 10-month self-care program for pacemaker patients. In the present study, there were no significant differences in HRQoL when comparisons were made between the experimental group and the control group. Results show two main findings for patients in the self-care program (n = 97; mean age 71 years): a significantly better HRQoL in terms of experiencing the symptoms that were the reason for pacemaker implantation, as having decreased or disappeared, and a higher level of perceived exertion in a 1 1/2-minute stair test compared with patients who had standard checkups (n = 115; mean age 73 years). It is important to actively include pacemaker patients in a self-care program while still in the acute phase in the hospital. Health care professionals should support the patient in a kind and professional manner by providing clear, relevant information, and planning a self-care program based on the nurse's assessment of the patient's needs. To enable patients to manage their life situations, training and continued education for health care professionals is necessary so that their efforts are based on a holistic approach to nursing care and recognition of the patient perspective, with emphasis on developing education and counselling for women, patients with atrial fibrillation/sick sinus disease, and patients whose pacemakers have ventricular pacing.

Clinical predictors of health-related quality of life after pacemaker implantation

BACKGROUND

Health-related quality of life (HRQL) is increasingly accepted as an outcome measure when considering the effectiveness of therapeutic interventions. Little is known about the HRQL of patients with different clinical circumstances before and after pacemaker implantation (PMI). The purpose of this study was to investigate the influence of clinical symptoms and ECG diagnoses as predictors of improved HRQL in patients referred for PMI.

METHODS

Sixty eight patients with different indications for PMI completed the MacNew Heart Disease Health-related Quality of Life Questionnaire (MacNew) and the Short Form-36 Health Survey (SF-36) before and one, three and six months after PMI. Symptoms, ECG indications and pacing mode were collected using the European Pacemaker Patient Identification Card codes.

RESULTS

Within the first month after PMI overall Mac-New but not SF-36 scores improved significantly and was maintained during the entire 6 month follow up period. Improvement in HRQL as measured with the MacNew was rather related to baseline symptoms and ECG diagnosis than to the pacing mode.

CONCLUSION

The important finding of this study is that improved HRQL seen after PMI appears to be largely driven by baseline symptoms and the ECG diagnoses rather than the pacing mode of the device.

Implantation of a cardiac pacemaker –

BACKGROUND

An increasing number of cardiac pacemaker implantations are performed in the outpatient setting. Studies have compared costs and complication rates of outpatient versus inpatient pacemaker implantations but little is known on the subjective experience of the procedure by patients.

METHODS

Between 1999 and 2000, patients were prospectively included at admission to a teaching hospital and to an outpatient clinic for elective pacemaker implantations in Cottbus, Germany. Perioperative stress was assessed prior to the operation as well as on the day after the implantation and 3-4 days later. We used three validated questionnaires to assess stress: the "Short Questionnaire of Current Stress", the "Multidimensional Mood Questionnaire", and the "List of Mood and Emotion Descriptors".

RESULTS

A total of 138 patients were enrolled. Of those, 74 patients (mean age: 71+/-12 years; 45% female) had an outpatient implantation compared to 64 patients in the hospital setting (mean age: 73+/-12 years; 53% female). Stress was highest immediately prior to the implantation and lowest on day 3-4 in both groups. Inpatients were significantly less likely to experience agitation compared to outpatients (P=0.002). On the other hand, outpatients reported a significantly higher activity level. There were no differences regarding any of the other dimensions between the two groups.

CONCLUSION

Both in- and outpatient cardiac pacemaker implantation are associated with increased preoperative stress. In both groups, however, stress decreases rapidly following the intervention. In the referral of patients, sociodemographic factors such as area of residence will probably play the key role.

Hastening death and the boundaries of the self

When applying moral principles to concrete cases, we assume a background shared understanding of the boundaries of the persons to whom the principles apply. In most contexts, this assumption is unproblematic. However, in end-of-life contexts, when patients are receiving 'artificial' life-support, judgments about where a person's self begins and ends can become controversial. To illustrate this possibility, this paper presents a case in which a decision must be made whether to deactivate a patient's pacemaker as a means to hasten his death. After discussing some common moral principles that are often applied to resolve ethical problems at the end of life and after explaining why they are of no help here, the paper argues that the correct analysis of this case, and of cases of this sort, turns on considerations that relate to the constitution of the self. These considerations, the paper further argues, sometimes resist resolution. The constitution of the self is fixed in large measure by our concepts and social conventions, and these do not always provide determinate grounds for delimiting the boundaries of the self.

Health-related quality of life of patients with implantable cardioverter defibrillators compared with that of pacemaker recipients

AIMS

Studies indicate a poorer quality of life (QoL) for implantable cardioverter defibrillator (ICD) patients than for the general population. However, studies comparing the QoL of ICD patients with that of patients with other implantable cardiac devices are scarce. We hypothesized that ICD patients had a poorer QoL than pacemaker patients.

METHODS AND RESULTS

All ICD patients living in Iceland at the beginning of 2002 (44 subjects), and a comparison group of 81 randomly selected patients with pacemakers were invited to participate. The Icelandic Quality of Life Questionnaire (IQL), the General Health Questionnaire (GHQ), the Beck Anxiety Inventory (BAI), and the Beck Depression Inventory (BDI) were submitted to measure QoL, psychiatric distress, and symptoms of anxiety and depression. The ICD and pacemaker groups did not differ on IQL, BAI, BDI, or GHQ scores. ICD patients were as a group more fearful of death (P = 0.056) and showed more concerns about returning to work (P = 0.072), although these items fell just short of statistical significance.

CONCLUSION

Contrary to our expectations, ICD patients had a comparable QoL with pacemaker recipients and were not more likely to suffer from anxiety, depression, or general psychiatric distress. These findings are encouraging in view of expanding ICD indications.

Development of the implanted devices adjustment scale

Advances in microelectronics have resulted in exponential growth in the number of implanted medical devices. Most people do well adjusting to their devices, but others show signs of depression and/or anxiety. The Implanted Device Adjustment Scale (IDAS) was developed to measure how well a person is adjusting to an implanted device. First, a pool of items was generated and reviewed by 2 panels of clinicians and psychometricians for content validity. The revised version was then administered to a small sample that provided information about problematic items. Finally, a convenience sample of 45 persons (66% males) with implanted devices (18 pacemakers only, 37 cardioverter/defibrillators) completed the revised IDAS twice. After deleting weak items, the Cronbach alpha was 0.90. No age, gender, or device differences were found. Test-retest reliability was 0.92. The IDAS may be useful to evaluate how well a person is adjusting to her/his device. This may lead to more timely and appropriate interventions to improve outcomes.

Psychometric Properties of an Established Heart Disease Specific Health-related Quality of Life Questionnaire for Pacemaker Patients

Little is known about the HRQL of pacemaker patients due to the limited availability of disease-specific instruments. The aim of the Pacemaker Patients Quality of Life (PAPQoL) study was to determine the psychometric properties for the MacNew Heart Disease Health-related Quality of Life Questionnaire (MacNew) in patients before and after pacemaker implantation. Patients with a given indication for pacemaker therapy (N = 68) completed two self-administered HRQL instruments, the SF-36, a well-known and psychometrically sound health survey, and the MacNew, a reliable and valid heart-disease-specific HRQL instrument, before and one, three and six months after pacemaker implantation. We assessed disease severity with the New York Heart Association (NYHA) classification. Test-retest reliability, intra-class correlation, Cronbach's alpha, validity coefficients, sensitivity analyses (effect sizes) and confirmatory factor analysis were carried out. The MacNew demonstrated adequate reliability (Cronbach's alpha and ICCs > 0.80 on all scales), validity (correlations between similar SF-36 and MacNew subscales > 0.80), and responsiveness (all effect sizes > or = 0.67) in pacemaker patients. The MacNew demonstrates adequate psychometric properties for evaluating HRQL in patients before and after pacemaker implantation.

Measuring patient acceptance of implantable cardiac device therapy: initial psychometric investigation of the Florida Patient Acceptance Survey

INTRODUCTION

Patient acceptance of implantable device therapy has been established as an important outcome but the operationalization and validation of a measure of patient acceptance of implantable device therapy has not been fully completed. This study sought to validate a new measure of patient acceptance of cardiac implantable devices called the Florida Patient Acceptance Survey (FPAS).

METHODS

The sample consisted of implantable cardioverter defibrillator (ICD; n = 58), and implantable atrioverter defibrillator (ICD-AT; n = 96), and pacemaker (PM, n = 84) patients. Mean age of all participants was 69 years; they were mostly male (62%) and married (75%). The final FPAS comprised 15 items with four consistent factors: Return to Function, Device-Related Distress, Positive Appraisal, and Body Image Concerns.

RESULTS

The total FPAS demonstrated good internal consistency (Cronbach's alpha = 0.83), and internal consistency for each of the subscales ranged from 0.74 to 0.89. The FPAS demonstrated convergent, divergent, and discriminant validity when compared to other self-report measures of QOL, atrial symptoms, depression, and anxiety. A total FPAS score can be formed and between group comparisons with this sample indicated that ICD patients report a high level of acceptance (mean = 76), ICD-AT patients report a significantly higher level of acceptance (mean = 81.1), and PM patients reported the highest level of patient acceptance (mean = 85.4) of these implantable device groups.

CONCLUSION

This initial psychometric investigation of the FPAS suggests that the FPAS may be useful in both clinical and research settings to assess patient acceptance of implantable cardiac devices.

Pacemakers and Implantable Cardioverter Defibrillators:. Device Longevity Is More Important Than Smaller Size: The Patient's Viewpoint

The size of pacemakers and implantable cardioverter defibrillators (ICDs) has been diminishing progressively. If two devices are otherwise identical in components, features and technology, the one with a larger battery should have a longer service life. Therefore, patients who receive smaller devices may require more frequent surgery to replace the devices. It is uncertain whether this tradeoff for smaller size is desired by patients. We surveyed 156 patients to determine whether patients prefer a larger, longer-lasting device, or a smaller device that is less noticeable but requires more frequent surgery. The effects of subgroups were evaluated; these included body habitus, age, gender, and patients seen at time of pulse generator replacement (PGR), initial implant, or follow-up. Among 156 patients surveyed, 151 expressed a preference. Of these, 90.1% preferred the larger device and 9.9% the smaller device (P <0.0001). Among thin patients, 79.5% preferred a larger device. Ninety percent of males and 89.2% of females selected the larger device. Among younger patients (< or =72 years), 89.6% preferred the larger device, as did 90.5% of older patients (>72 years). Of patients undergoing PGR or initial implants, 95% favored the larger device, as did 86% of patients presenting for follow-up. The vast majority of patients prefer a larger device to reduce the number of potential replacement operations. This preference crosses the spectrum of those with a previously implanted device, those undergoing initial implants, those returning for routine follow-up, and patients of various ages, gender, and habitus.

Body image changes associated with dual-chamber pacemaker insertion in women

PURPOSE

The study's purpose was to examine body image changes in subjects participating in a long-term multicenter pacemaker trial.

METHODS

At study closeout, 383 adults, all of whom had received a dual-chamber pacemaker, completed questionnaires evaluating what effect their pacemaker or pacemaker site and scar had on them or their spouses or significant others.

RESULTS

Most reported that their pacemaker did not change the way they or their spouses or significant others felt about their body (73.2% and 93.5%, respectively). Most (87.1%) denied feeling differently because of the pacemaker site and scar. Most were not concerned how their clothes fit or about wearing a swimsuit (92.0% and 90.7%, respectively). Women were more concerned about how the pacemaker site and scar made them feel about their body (P =.001), clothes fitting (P =.002), and wearing a swimsuit (P =.004). Men were more concerned with how their spouses or significant others perceived them postimplantation (P =.021).

CONCLUSIONS

Most subjects did not express undue concern about changes in body image.

The postmodern heart: war veterans' experiences of invasive cardiac technology

BACKGROUND

The consequences of war and medical discourse have historical connections to pacemaker technology. Understanding these consequences is important because war veterans, medicine and cardiac technology have a shared history that continues into the present. The incidence of Australian war veterans needing cardiac pacemakers has increased many-fold in recent years, due to advancing age. This need was recognized by the Australian Department of Veteran Affairs and a cardiac programme was established in the veteran hospital that was the setting for this study.

AIM

This paper reports on a study aimed at capturing the interest and sensitizing the practice of nurses involved in the care of war veterans and other health care consumers who have been diagnosed as requiring a cardiac pacemaker. The study sought to answer the question, 'How does the war veteran experience his body in relation to invasive cardiac technology?'.

METHOD

The research was guided by the principles of interpretive interactionism, and used unstructured interviews with eight male war veterans. The data were collected in 2000.

FINDINGS

Thematic and content analysis revealed five themes: emotional knowing; the medical encounter; belief in the myth of miracle; technological constraint; and the altered heart. The findings indicated that the human dimension was characterized by experiences of ambivalence, inner conflict, powerlessness and suffering.

CONCLUSION

Nursing is at the interface of science and patient care, and this study contributes to nursing knowledge by focusing on a previously unresearched topic, namely embodied interactions between war veterans and invasive cardiac pacemakers. Within a highly technical area such as cardiology, nurses can still work around the technology and keep patients as their primary focus, thus promoting quality care. A humanistic rather than a technological focus locates nurses between patients and cardiac technology. In this in-between location, nurses are not an extension of cardiac technology but a valuable source of information, education, and counselling.

Emotion and cardiac technology: an interpretive study

This paper presents a frequently overlooked aspect of advanced technological care--that of the human dimension and emotions. Emotionality is defined as the emotional ways that a client experiences their embodied experience as a recipient of a cardiac pacemaker. One individual's story from a larger interpretive study of clients who received pacemakers is presented and interpreted. Kev's story encapsulates the difficulties of dealing with and understanding cardiac technology. When Kev's heart malfunctions he confronts a new reality; an experience where the 'technological body' is linked confusingly with emotion. This complex interplay between technology, the body and emotionality is discussed to demonstrate the importance of the mediating role that nurses can and should play in clients' adaptation and recovery.

Change in quality of life in patients with permanent cardiac pacemakers: a six-month follow-up study

The purpose of this study was to investigate the quality of life (QOL) in patients before and after permanent pacemaker implantation. A follow-up study design was adopted and purposive sampling was applied to recruit subjects from two medical centers in Taipei City. Subjects were interviewed before pacemaker implantation. Follow-up interviews were conducted at second, fourth, and sixth month after pacemaker implantation. There were 42 subjects enrolled in this study. These subjects had moderate QOL (62.4 +/- 15.9 on a scale of 97) before pacemaker implantation and the QOL improved significantly after pacemaker implantation(p <.05). The QOL improvement reached a peak at the end of the fourth month and the scores decreased at the end of the sixth month vs. the fourth month (p <.05). They had significant improvement in general well-being, sleeping, appetite, physical activity, and physical symptoms (p <.05), but not in cognitive function, social participation, work capability and sexual function (p >.05). Subjects with spouses as their main caregivers had significantly better improvement in QOL after pacemaker implantation. Subjects perceptions of distress from arrhythmia were the most significant determinant in their QOL pre and post pacemaker implantation. The findings suggest that aggressively resolving arrhythmia distress is important for improving QOL.

Focused life stories of women with cardiac pacemakers

Biotechnical devices such as cardiac pacemakers are implanted into people to manage a range of disorders, yet comparatively little is known about the emotional impact of this experience. Women may have a unique response to implanted devices due to cultural messages about the masculinity of technology. In this qualitative study using Hall's focused life stories design, 11 women from teenagers to elders with permanent cardiac pacemakers were asked to describe their experiences using semistructured interviews. The themes that emerged are relinquishing care, owning the device, experiencing fears and/or resistance, imaging the body, normalizing, positioning as caretaker, finding resilience, and sensing omnipotence. Understanding what it means for women to live with an implanted biotechnical device may facilitate planning interventions to support their psychological and physiological health. Effective pacemaker function may depend, in part, on recipients' successful emotional attachment to the device.

How different from pacemaker patients are recipients of implantable cardioverter-defibrillators with respect to psychosocial adaptation, affective disorders, and quality of life?

OBJECTIVE

To assess differences in psychosocial adaptation, quality of life, and incidence of affective disorders between patients with pacemakers and those with implantable cardioverter-defibrillators (ICDs).

DESIGN

Patients aged 40-70 years who underwent a first pectoral implantation of a pacemaker or an ICD system were studied. All subjects were asked to complete the hospital anxiety and depression scale (HAD), the short form general health survey (SF-36), and a specially designed device related questionnaire. Data analysis was performed for three patient groups: pacemaker (n = 76), ICD patients who received therapeutic shocks (n = 45), and ICD patients who did not receive shocks (n = 31).

RESULTS

There were no differences between the three patient groups in HAD scores or in any of the SF-36 subscales or summary ratings. Probable depressive disorder (depression score > 10) was observed in 5.2%, 6.5%, and 6.6%, and probable anxiety disorder (anxiety score > 10) in 13.1%, 9.7%, 13.3% of the pacemaker, non-shocked ICD, and shocked ICD patients, respectively. There were no sex differences. However, patients in the shocked ICD group were more likely than those in the other groups to report limitations in their leisure activities, to perceive their device as a "life extender," and to admit anxiety about battery depletion and technical problems. Forty per cent of shocked ICD patients would be interested in joining a support group.

CONCLUSIONS

Despite having distinctly different medical histories and treatments, patients with pacemakers and ICDs responded similarly to validated tools of health status assessment. ICD patients who had received shocks perceived their device as prolonging their life and had greater anxiety about technical problems. Their endorsement of the potential benefits of a support group warrants further investigation.

Psychometric properties of Aquarel. a disease-specific quality of life questionnaire for pacemaker patients

In cardiac pacing current clinical practice permits the use of ventricular or atrioventricular-synchronous pacemakers. However, it is not known which type of pacemaker results in superior clinical and patient outcomes. To date, there is no feasible and validated disease-specific questionnaire for pacemaker patients to assess quality of life (QoL) available. The Aquarel questionnaire was developed as a disease-specific extension to the Short-Form-36 (SF-36). A cross-sectional study was carried out in 74 pacemaker patients to evaluate validity and reliability of this instrument. Items were selected and scales constructed based on factorial analysis. Internal consistency, content validity and test-retest reliability were moderate to excellent. Correlations with the SF-36 scales, pacing mode and functional tests were as hypothesized, demonstrating the individual value and distinctiveness of the Aquarel subscales. The results support the feasibility and usefulness of evaluating QoL in pacemaker patients when using Aquarel as an extension to the SF-36.

Quality-of-life of pacemaker patients: a reappraisal of current instruments

Current clinical practice permits the use of single chamber ventricular or dual chamber pacemakers. However, it is not known which type of pacemaker results in superior clinical and patient outcomes. This is of growing importance because of the higher costs and increased risk of technical failures of dual chamber pacemakers. Patient outcomes can be assessed with quality of life questionnaires, but it is unclear which questionnaires are valid for use in pacemaker patients. This article reappraises studies on quality of life instruments for pacemaker patients. We searched MEDLINE (1985-1998) for studies assessing quality-of-life in general and in pacemaker patients. The SF-36 appeared to be the best among generic questionnaires because of its psychometric characteristics and experience of use. Concerning disease specific instruments, the Karolinska quality of life questionnaire has desirable content validity but lacks more rigorous psychometric validation, which constitutes a serious limitation. Previous studies suggested that implantation of atrioventricular pacemakers improves quality-of-life compared to ventricular pacemakers, but since no well-designed and validated questionnaire exists, these results should be interpreted with caution. The best outcome measure to evaluate quality-of-life in pacemaker patients would be a combination of a generic health profile with established reliability and validity supplemented with a cardiovascular assessment adjusted to suit pacemaker patients. By doing so, individual scores can be compared within a disease cohort and to same-aged, nondiseased persons, as well as other diseased populations. The development and validation of such an instrument is currently needed.

[Patients with diaphragmatic pacemakers]

Due to the implantation of diaphragmatic pacemakers, the hope and quality of life for those with upper spinal column injuries has increased considerably. Until about 10 years ago, these patients depended on a mechanical ventilator with all of its corresponding limitations. Nurses have had to learn how to use diaphragmatic pacemakers so they may provide patients with the specific treatment these make available and so that they may offer adequate health education to relatives of these patients. The greatest challenge for our profession is to succeed in having these patients abandon the hospital and integrate into society again. This article analyzes how diaphragmatic pacemakers work and the specific nursing treatment these patients require, placing emphasis on psycho-sociological aspects.

Learning retention in patients receiving midazolam during permanent pacemaker implantation

This pilot study (N = 20) tested the effects of intravenous midazolam administration on learning retention after pacemaker implantation. Patients were randomized to receive teaching at 1 or 3 hours after the last dose of midazolam. Using a standardized teaching format, one of two study nurses performed the teaching that included incision care, activity restrictions, environmental factors potentially affecting pacemaker function, and follow-up requirements. Learning was evaluated by one of the investigators blinded to teaching time. Subjects in the 1-hour group retained significantly less information than those taught at 3 hours after drug administration. Patients taught later answered similar numbers of questions correctly, whereas there was much more variability in correct responses for the group taught earlier. This article reviews the effects of midazolam on memory and learning as well as provides suggestions for alterations in patient education protocols for patients receiving midazolam for pacemaker implantation. The effect of shortened length of stay on care practices is also discussed.

Final-year-of life pacemaker recipients

BACKGROUND

Older persons who have initial cardiac pacemakers implanted during their final year of life have not been characterized as a group, which makes it difficult to evaluate the suitability of some of their health services utilizations.

OBJECTIVE

To help determine how prudently pacemakers are used in this group, we assessed its pacemaker candidates from the perspective of health and ability to perform physical activities of daily living.

DESIGN

A retrospective, population-based, cross-sectional study.

SETTING

The 1993 National Mortality Followback Survey.

PARTICIPANTS

An estimated 1,647,955 persons aged 65 years or older who died in the US in 1993.

MEASUREMENTS

Demographic and cause-of-death frequencies obtained by analyzing age, sex, race, and underlying cause-of-death variables in the survey. For persons who had initial pacemakers implanted during their last year of life, we determined the percent of persons, within 10-year age groups, who had no difficulty at any time during their final year of life performing 11 specific physical activities of daily living (e.g., climbing stairs, preparing meals, bathing). These data were obtained from negative responses to questions that asked if the decedents, at any time during their last year of life, had difficulty performing the specific activities.

RESULTS

Of the estimated 78,941 persons aged 65 years or older with a pacemaker who died in the US in 1993, 14,158 (18%) had their first pacemaker implanted during their last year of life. Estimated median survival of the final-year-of-life recipients of pacemakers after pacemaker implantation was 5 months. Compared with the general older population that died in 1993, the final-year-of-life recipients of pacemakers group had higher percentages of persons who died of acute disorders (49% vs 19%) and who lived alone in a private home (47% vs 20%), and a lower percentage of persons with Alzheimer's disease (1% vs 7%). The age-stratified means of the percentages of final-year-of-life recipients of pacemakers who had no difficulty performing each physical activity of daily living were all greater than 50.

CONCLUSION

Our results suggest that older persons who had initial pacemakers implanted during their final year of life and who died in 1993 were not terminally ill, inactive pacemaker candidates, in general, but relatively independent, physically functional candidates who frequently died abruptly. The physical, mental, and life expectancy factors recommended for consideration by expert guidelines for the implantation of cardiac pacemakers were generally applied to persons in this subgroup.

Psychiatric morbidity and depressive symptomatology in patients with permanent pacemakers

Implantation of a permanent pacemaker requires a psychological effort on the patient's part for adaptation in the acute term, and chronically, it restricts activities of the patient and may cause some psychiatric disturbances. To investigate psychiatric morbidity and depressive symptomatology of the patients with permanent pacemakers, 84 pacemaker patients were diagnosed using the DSM-III-R criteria and depressive symptoms were determined by modified Hamilton Depression Rating Scale (mHDRS). Sixteen (19.1%) patients had been given a psychiatric diagnosis. The most frequent diagnoses were adjustment disorder (5.9%) and major depressive episode (4.7%). Nine patients (10.7%) were diagnosed as having clinical depression (mHDRS > or = 17). The mean score of mHDRS was 7.57 +/- 7.46, and the severity of depression was significantly higher in females. The most frequent symptoms are difficulties in work and activities (53.6%), psychic anxiety (48.8%), loss of energy (42.9%), and hypochondriasis and insomnia (39.3%). Depressed mood, psychic anxiety, loss of energy, loss of interest, insomnia, and hypochondriasis were significantly more frequent in females. Uneducated patients had a more significant loss of energy than educated patients. Depressed mood, psychic anxiety, and somatic concerns and symptoms were more frequent in patients with permanent pacemakers than in the general population. These symptoms, resembling mixed anxiety-depression disorder, were related to fears of having a permanent pacemaker, since our series were composed of uneducated patients who did not have enough knowledge about the device.

Maintaining physiological pacing in AV block using a new generation single lead VDD pacemaker

OBJECTIVE

A prospective evaluation of patients with AV block using a single pass lead, VDD pacing system.

DESIGN

Fifteen patients with AV block, eight males, seven females, average age 68.1 years (range 22.3 to 86.5) were implanted with the THERA VDD 8948 pacemaker and 5032 single pass steroid eluting lead (Medtronic, Inc). P wave sensing and ventricular thresholds were done predischarge and at one, three, and six months and subsequent six-month periods postimplant. P wave sensing was evaluated with exercise testing and other provocative tests. Twenty-four hour Holter monitoring was done before discharge. Patients were given a quality of life questionnaire pre- and postimplant.

SETTING

Tertiary care hospital.

RESULTS

Average follow-up was 6.4 months (1.5 to 18). Ventricular thresholds remained stable. P wave amplitude at implant (average 2.2 mV; 1.6 to 3.6) showed a significant decrease at the initial visit (average 1.1 mV, 0.5 to 2.4), however, it remained stable at subsequent visits. This initial decrease had no clinical significance as the maximum atrial sensitivity of the device is 0.18 mV. The 24 hr Holter monitoring confirmed reliable AV synchronous pacing in 14 of 15 patient pacemakers programmed in the VDD mode. The sleep function maintained AV synchrony during nocturnal bradycardia; atrial rate histograms available at follow-up imply appropriate intrinsic rate variation and provocative sensing tests and exercise protocol demonstrated reliable atrial sensing. There was a significant improvement in overall patient well-being score using a quality of life questionnaire.

CONCLUSIONS

During the follow-up period, this new generation VDD pacemaker, using a single pass lead, provided reliable AV synchronous pacing for patients diagnosed with AV block and normal sinus node function, as well as improved patient well-being.

Medical devices and attachment: holistic healing in the age of invasive technology

The environment is filled with wonderful examples of medical technology that provide emergency life support, improve well-being, and offer the possibility of a longer and more productive life. But these devices are no longer only a part of the external environment. As technology advances, more devices are becoming a part of the internal environment (i.e., our bodies) as well. For some people an implanted mechanical device, such as a cardiac pacemaker or a cardioverter defibrillator, is readily accepted; for others it may be seen as an encroachment. It may be a symbol of loss and debilitation or of independence and resilience. What makes the difference? How can nurses facilitate a healthy adjustment and healing in an era permeated with technology? A discussion of the symbolism, related theory, and nursing implications is provided.

[Quality of life in patients with pacemakers]

INTRODUCTION AND OBJECTIVES

On the occasion of the doctoral thesis "Epidemiologic study in pacemaker patients", the social and some health factors around the pacemaker patient has been studied.

METHODS

Data were obtained by a patient verbal questionnaire and the pacemaker follow-up form. The social parameters studied are: employment aspects, change life feeling, health feeling, sporting activity and change of intensity of pharmacologic treatment. Just to get alone a quantitative social parameter, a social resulting punctuation or "social balance" has been designed. It has been used in bi-variable relation against the symptoms, electrocardiogram, complications, time from the pacemaker implantation, pacemaker type, dependence of the pacemaker and social variables between himself. Among the 108 variables considered, it has been studied which of them had more weight in the "pacemaker profitability". Greatest profitability (and vice versa): greatest profit in symptoms and in social conditions, smallest number of complications; greater time passed and worst evolution of electrocardiogram. The numerical value of the "profitability" is set up by assigning 20 points to each foregoing concepts, obtaining a greatest theoretical punctuation of 100 points and a smallest of 0 points.

RESULTS

We obtained values of arithmetical mean, a frequency profile of quality life parameters, a profile of the better and worst situation in the bi-variable relation and the definition of those social factors who contributed to the segmentation of the "pacemaker profitability".

CONCLUSIONS

The kind of job and the time of going out of it after the pacemaker implantation, the changing life feeling, the health feeling after the pacemaker and the transport means to the hospital are the variables which contributed to discriminate the major and the minor profitability.

[Psychosomatic aspects of pacemaker therapy]

Modern pacemaker therapy offers a highly differentiated treatment of symptomatic bradycardia, hardly susceptible to failure, combined with low operative intervention and risk. Only little attention has been paid to psychosocial aspects during the past; this explains the sketchy knowledge of this field. Prior to implantation there is, at first, a high rate of depression, which decreases after the operation. A number of favourable and unfavourable factors are described, concerning the acute and the long-term adaptation to the unit. Emotional and cognitive functions usually improve significantly during the follow-up period compared to the pre-operative state. This fact as well as social rehabilitation, which can only be realized partially, lead to an acceptable quality of life; therefore, for the majority of pacemaker patients, no essential modification of the usual control examinations seems to be necessary. But a small group of risk patients need the enhanced attention of their cardiologists and eventually interdisciplinary assistance.

[Munchausen syndrome by proxy]

The term "Munchausen by proxy" denotes a special form of factitious disorder and a rare kind of child abuse. We present the case of a 12-year-old boy, whose mother's manipulations culminated in his immobilization in a wheelchair and the implantation of a pacemaker. Problems of diagnosis and clinical management of Munchausen by proxy are discussed.

Patient acceptance of implantable cardioverter defibrillator devices: changing attitudes

Clinical experience suggests that the implantable cardioverter defibrillator (ICD) can reduce sudden cardiac death and total mortality in patients with malignant ventricular arrhythmia who meet the selection criteria for implantation. In addition to surgical problems, patients are faced with psychological and social adjustments. Patient acceptance for such therapy is marked by perceived concerns regarding device discharge, life-style alterations, and complications. We included 57 patients with ICDs in a study of their acceptance of the device. Results of a specially designed questionnaire (state-trait personality inventory) showed that 47 of 57 patients felt that their symptoms improved with the ICD system, 32 were constantly aware of the device, and 24 patients acclimated to the ICD system within less than 2 months. With respect to the need for battery replacement, only 27 patients requested a repeat electrophysiologic evaluation, 20 patients stated fear of ICD discharges, 12 patients revealed physical discomfort from the device, and limited quality of life occurred in eight patients. Fifty-five of 57 patients answered that it was worth having an ICD device implanted, 30 (53%) patients returned to active life, and 56 (98%) would advise another patient to have an ICD implantation if necessary. In conclusion, in general, the acceptance of the ICD as a tool for management of life-threatening ventricular tachyarrhythmias is very high. Quality of life and patient acceptance are important criteria for successful ICD therapy in addition to the improved survival rate.
