Psychological distress of surgical patients after orthotopic heart transplantation

Complication Is Inevitable, but Suffering is Optional-Psychological Aspects of Dealing with Complications in Surgery

Surgical complications remain common in health care and constitute a significant challenge for hospitals, surgeons, and patients. While they cause significant physical, financial, and psychological harm to patients and their families, they also heavily burden the involved physicians. This phenomenon, known as the "second victim," results in negative short and long-term physical, cognitive, and psychological consequences on the surgeon. In this review, we explored the intricate connections between the surgeons' emotional response to adverse events concerning the patient outcome, perceived peer reaction, and existing social and institutional support systems. Using a selective literature review coupled with personal experiences, we propose a model of this complex interaction and suggest specific interventions to ameliorate the severity of response within this framework. The institution of the proposed interventions may improve the psychological well-being of surgeons facing complications and promote a cultural shift to better support physicians when they occur.

Role of Personal Resources in Depression and Stress in Heart Transplant Recipients

BACKGROUND

Heart transplantation is the primary option for heart failure treatment and increases the survival rate and the quality of life for recipients. However, this surgical intervention induces numerous psychological problems, such as depression and anxiety. Protective factors and personal recourses are a significant force behind healthy adjustment to life stresses. The aim of this study was to assess the role of personal recourses in terms of depression and stress in heart transplant recipients.

METHODS

The study involved a sample of 131 post-heart transplant patients. Standardized instruments were used to measure the key constructs: Beck Depression Inventory Short Form for prevalence of depression, Perceived Stress Scale for prevalence distress, and Sense of Coherence (SOC-29), Life Orientation Test, and General Self-Efficacy Scale for measuring personal resources.

RESULTS

We found that sense of coherence, optimism, and self-efficacy proved to be significant predictors for the prevalence of both depression and stress.

CONCLUSIONS

These result suggest that the assessment of coping strategies and sense of coherence in heart transplant recipients requires exploration. Evaluating coping strategies and sense of coherence before surgery seems significant and begins with developing skills in this domain.

Deservingness and gratitude in the context of heart transplantation

Heart transplantation is now routinely offered as a treatment for end-stage heart failure, and the "gift-of-life" metaphor has become pervasive in this context, forming the foundation on which transplantation discourses rest. In this article, we question organ-as-gift understandings of transplantation. One can also legitimately think of the transplanted organ as a donation, with distinct implications in terms of the transplantation experience for the recipient. We explored the transplantation experience of 13 heart recipients in Australia. We conducted semistructured interviews, and our interpretative phenomenological analysis of the data resulted in three themes: deservingness, nuances of gratitude, and giving forward. Our results indicate that differences between organ-as-gift and organ-as-donation understandings of transplantation are more than merely semantic. Organ-as-donation understandings raise the issue of deservingness, with recipients' assessments of their worthiness influencing their posttransplant experience of gratitude and, ultimately, the meaning(s) gleaned from their transplant experiences.

Factors associated with stress and coping at 5 and 10 years after heart transplantation

BACKGROUND

Heart transplant-related stressors and coping are related to poor outcomes early after transplant. The purposes of our study were to (1) identify the most frequent and bothersome stressors and most used and effective coping strategies and (2) compare the most frequent and bothersome stresses and most used and effective coping styles between patients at 5 and 10 years after heart transplantation. We also examined differences in coping styles by patient characteristics and factors associated with frequency and intensity of stress at 5 and 10 years after heart transplantation.

METHODS

This report is a secondary analysis of data from a prospective, multisite study of quality of life outcomes. Data are from separate cohorts of 199 patients at 5 years after transplant and 98 patients at 10 years. Patients completed the Heart Transplant Stressor Scale and Jalowiec Coping Scale. Statistical analyses included frequencies, measures of central tendency, t-tests, chi-square, and generalized linear models.

RESULTS

At 5 and 10 years after heart transplantation, the most bothersome stressors were regarding work, school, and financial issues. Patients who were 10 years after transplant reported less stress, similar stress intensity, and less use and perceived effectiveness of negative coping than patients who were 5 years after transplant. Long-term after transplant, demographic characteristics, psychologic problems, negative coping, and clinical factors were related to stress frequency and/or intensity.

CONCLUSIONS

Heart transplant-related stress occurs long-term after surgery. Types of transplant-related stress and factors related to stress confirm the importance of ongoing psychologic and clinical support after heart transplantation.

The occurence of mood and anxiety disorders in heart transplant recipients

Fortynine heart transplant recipients were evaluated during the first weeks after orthotopic heart transplantation. Using the ICD-10 (International Classification of Diseases-10th revision) criteria, we studied the incidence of anxiety disorders as well as 17 demographic and medical factors potentially influencing the probability of their occurrence. A smaller 36-person group was evaluated using standard psychopathologic scales for anxiety and mood disorders. Cox regression analysis was used to specify which of 11 demographic and medical factors influenced the time to occurrence of the first episode of a mental disorder. Anxiety episodes occurred in 25 patients, depressive episodes in 27, (hypo)manic in 3, and 12 manifested a slightly elevated mood. The risk of occurrence of anxiety and mood disorders was highest during the first 3 weeks after OHT. "False alarms," namely, calls to the clinic not ending up in transplantation, and coexisting illnesses were related to higher incidences and earlier appearance of anxiety and mood disorders. The risk of occurrence of an anxiety syndrome was greater among older patients. Anxiety syndromes were manifested earlier in patients who underwent transplantation due to ischemic cardiomyopathy than in patients with heart failure caused by other factors. A greater number of false alarms, of long-lasting hospitalizations, and of low mean cyclosporine levels were risk factors for depressive episodes.

Comparison of hospital-supervised exercise versus home-based exercise in patients after orthotopic heart transplantation: effects on functional capacity, quality of life, and psychological symptoms

In heart transplant patients it is common to observe a reduced exercise capacity and diminished quality of life. The objective of this study was to compare the effectiveness of a hospital-based exercise program versus that of a home-based exercise program on the functional capacity, quality of life, and psychological symptoms among heart transplant patients.

METHODS

Thirty-eight heart transplant patients were randomly placed into two groups: a hospital-based exercise program (group 1, n = 15) or a home-based exercise program (group 2, n = 13). All patients performed flexibility, stretching, aerobic, strengthening, breathing, and relaxation exercise programs for 8 weeks. We performed estimates of functional capacity (maximal oxygen consumption-pVO2), quality of life (Short Form-36-SF36), and psychological symptoms (Beck Depression Inventory-BDI, the State-Trait Anxiety Inventory-STAI).

RESULTS

In group 1, significant increases were observed in pVO2 and all SF36 subgroups, with the exception of vitality and social function subgroups (P < .05). Significant increases were not observed on the BDI or STAI (P > .05). Group 2 failed to show significant improvements in any variable, with the exception of the score on the bodily pain subgroup of the SF36 (P > .05).

CONCLUSION

Based on our clinical results, we recommend a well-organized exercise program performed in a rehabilitation unit to improve postoperative exercise capacity and quality of life among heart transplant patients.

The relationship between depressive symptoms and anxiety and quality of life and functional capacity in heart transplant patients

OBJECTIVE

To establish the relationship between depressive symptoms and anxiety with both the quality of life and functional capacity of heart transplant patients.

METHODS

Thirty-four patients were included. Outcome measures were the Beck Depression Inventory (BDI), the State- Trait Anxiety Inventory (STAI), the Short Form 36 (SF36) and peak oxygen consumption (pVO2).

RESULTS

After the transplant there was a significant negative correlation between the BDI and most of subgroups on the SF36 (p<0.05). There were significant negative correlations found between the pVO2 and both the BDI and STAI-trait anxiety score (p<0.05). Statistically significant improvements were noted in all subgroups on the SF36 and all BDI scores after the transplant, in comparison to the pre-transplant period (p<0.05).

CONCLUSIONS

The functional capacity of a person affects the state of their depression and anxiety. We recommend participation in a cardiac rehabilitation program in the early stages of transplantation and believe that the quality of life, which has been shown to be related to the functional capacity and psychological symptoms, would benefit from this program.

Mechanical Circulatory Support as a Bridge to Heart Transplantation: What Remains? Long-term Emotional Sequelae in Patients and Spouses

BACKGROUND

Implantation of a ventricular assist device (VAD) reduces short-term mortality and morbidity and provides patients with reasonable quality of life even though it may also be a long-lasting emotional burden. This study was conducted to analyze the long-time emotional consequences of VAD implantation, followed by heart transplantation in patients and spouses.

METHODS

This cross-sectional study used the Impact of Event Scale-Revised (IES-R) Version, recording avoidance, intrusion, and hyperarousal, to investigate symptoms of post-traumatic stress disorder (PTSD), and VAD-related fears and concerns. The study cohort comprised 38 patients (36 men, 2 women) and 27 spouses (26 women, 1 man), 6 to 135 months post-operatively.

RESULTS

Seven (26%) of the 27 spouses but none of the patients met the criteria for PTSD. Patients who were operated at the early stage of our VAD program (82.0 +/- 31.4 months between implantation and evaluation) were significantly more likely to have a spouse with PTSD syndromes than those whose operation took place later on (42.1 +/- 31.1 months, p = 0.007). Patients with higher avoidance scores and a higher level of hyperarousal were significantly more often affiliated with a PTSD spouse than those with lower avoidance (p = 0.008) and hyperarousal scores (p = 0.001). Spouses displayed significantly higher scores in all IES-R dimensions, and they worried more about device-related problems (malfunctioning, pain, infection, and stroke) than the patients themselves. The noise of the device system was not a crucial issue.

CONCLUSION

Our study found that implantation of a VAD, followed by transplantation, does not lead to PTSD in patients but it does in their spouses in the long run. Their emotional well being deserves much closer attention.

Psychological disorders and distress after adult cardiothoracic transplantation

This review summarizes and integrates evidence concerning mental health outcomes following heart, lung, and heart-lung transplantation. Drawing on English-language case reports and empirical studies published between January 1980 and December 2004, the goals of the review were to (a) describe the prevalence and clinical characteristics of psychological disorders, as well as the level and pattern of clinically significant distress in the years posttransplant; (b) review the major risk factors for poor posttransplant psychological outcomes; (c) consider evidence suggesting that posttransplant psychological outcomes predict physical morbidity and mortality after transplant; (d) summarize findings from intervention studies designed to improve posttransplant psychological outcomes; and (e) provide patient care recommendations for the practicing clinician and recommendations for continued clinical research. Several major conclusions can be drawn from this literature. First, depressive and anxiety-related disorders and associated distress are common posttransplant. While new onsets of disorder may decline after the first year posttransplant, the development of new medical complications in the late years posttransplant may provoke renewed distress and recurrences of disorder. Second, risk factors for posttransplant psychological disorders and elevated distress include both standard risk factors observed in other populations (eg, younger age, lifetime history of psychiatric disorder) and transplant-specific factors related to physical functional impairments, social supports, and strategies for coping with health problems. Third, while little evidence has been published to date, there is some indication that posttransplant psychological outcomes can predict subsequent physical health outcomes. Fourth, extremely few intervention studies in cardiothoracic transplant recipients have been performed. The few reports indicate that multicomponent psychosocial strategies focused on risk factor reduction and enhancement of personal coping resources may lead to reductions in psychological distress. An important caveat in considering all of the evidence reviewed is that most studies focus on heart rather than lung or heart-lung recipients. Recommendations for practicing clinicians focus on assessment and treatment options, based on the evidence to date. Research recommendations focus on the need for intervention effectiveness studies.

Two-year follow-up of quality of life in patients referred for heart transplant

BACKGROUND

Assessment of physical and mental health has become one of the ultimate tests of health-related quality of life (HRQOL) for patients with advanced heart failure. Little is known, however, about the comparative effects of surgical or medical treatment on the HRQOL of these chronically ill patients over time.

METHODS

We examined 77 patients (74% of whom were male), aged 56.1 +/- 12.7 years who were referred for heart transplant evaluation at a single heart failure center to describe the effects of time and treatment status on changes in HRQOL scores (physical and mental health and depression) using the Short Form-12 and the Beck Depression Inventory at 2 time points during their illness trajectory. The 2 evaluations on average were 2 years apart (mean 24.5 +/- 2.8 months). All patients were evaluated at baseline, and 3 groups were identified at the time of the 2-year follow-up: transplant recipients (n = 17), transplant candidates (n = 13), and medically stable patients considered too well to receive a transplant (n = 47). Nonparametric statistics were used to analyze group differences in HRQOL scores. The significance level was set at a P value less than .05.

RESULTS

Demographic and HRQOL scores were not significantly different among the 3 groups at baseline. During follow-up, physical health and depression scores significantly improved over time in all patients, but changes in mental health were minimal. Group comparisons showed that although all patients continued to have low HRQOL scores at the time of follow-up evaluation, medically stable patients had higher mental health scores and less depressive symptoms than their counterparts.

CONCLUSION

Our results support the need for ongoing HRQOL assessment with an emphasis on timely recognition and treatment of psychologic distress throughout the heart failure illness trajectory. Heart transplant recipients and candidates equally need special attention and follow-up because they both seem to have emotional and psychologic repercussions.

Posttraumatic stress disorder after implantation of a Mechanical Assist Device Followed by Heart Transplantation: Evaluation of Patients and Partners

AIM

We sought to investigate the prevalence of posttraumatic stress disorder, anxiety, and depression in patients and their partners after implantation of a mechanical assist device as a bridge to heart transplantation.

METHODS

This was a retrospective assessment of 41 patients (age 46.3 +/- 12.0 years; male-female ratio, 38:3; time since transplantation, 55.3 +/- 34.2 months [range, 7-122 months) and 27 partners (male-female ratio 2:25) by standardized instruments (Impact of Event Scale, Hospital Anxiety and Depression Scale), in 2 University Heart Transplant Centers (Vienna, Austria, Munster, Germany). The duration of the support systems (MicroMed DeBakey-VAD in 17 patients, Novacor in 10, Thoratec in 8, TCI HeartMate in 5, and Berlin Heart Incor in 1 patient) ranged from 28 to 711 (176 +/- 146) days.

RESULTS

None of the patients, but 23% of the partners (n = 6), met the criteria for posttraumatic stress disorder (Maercker cutoff >0). The Impact of Event Scale (IES) sum scales differed significantly between the 2 groups (21.2 +/- 15.1, mean +/- SD) for the patients versus 38.1 +/- 27.8 for the partners, respectively; P = .001). Two percent of the patients, but 19% of the partners, showed mild to moderate depression; 4% of patients, but 23% of their partners, reported mild to moderate anxiety. None of the results were significantly influenced by the time since transplantation, patient age, diagnoses, type of assist device, or indication for heart transplantation.

CONCLUSIONS

Despite patients being much closer to a life threat, their partners experience significantly more psychologic distress even in the long run. Our findings highlight the need for attention to the supporting persons.

An internet-based intervention to improve psychosocial outcomes in heart transplant recipients and family caregivers: development and evaluation

BACKGROUND

Although quality of life (QOL) is generally improved by heart transplantation, medical noncompliance and mental health and QOL limitations often emerge and persist. Transplant teams' ability to address these issues is hampered because many patients reside long distances from the transplant program. We therefore conducted the first empirical evaluation of an internet-based psychosocial intervention for heart recipients and their families.

METHODS

Based on focus group work and previous research, a multifaceted web-based intervention was developed with stress and medical regimen management workshops; monitored discussion groups; access to electronic communication with the transplant team; and information on transplant-related health issues. Intervention effectiveness was evaluated with 20 patients and family caregivers who used the website for 4 months (plus usual clinical care). Pre- and post-intervention assessments of mental health, QOL and medical compliance were performed. Comparison groups of 40 patients and their caregivers who received only usual care were similarly assessed.

RESULTS

Relative to the comparison groups, intervention patients' depressive and anxiety symptoms, and caregivers' anxiety and hostility symptoms declined significantly (P < 0.05). QOL in social functioning significantly improved. Mental health and QOL benefits were greater among more frequent users of the website. Overall, intervention patients' medical compliance did not change. However, the sub-group using the website's medical regimen workshop showed significantly better compliance at follow-up than all other patients in attending clinic appointments, completing blood work and following diet.

CONCLUSIONS

These preliminary findings suggest that a web-based intervention could have a vital role in follow-up care and in patients' and families' adjustment to heart transplantation.
