Lifestyle and quality of life in long-term cardiac transplant recipients

Pretransplant variables associated with quality of life in liver transplant recipients

OBJECTIVE

With an increasing number of liver transplant recipients living, understanding quality-of-life issues is essential. Our goal is to identify pretransplant variables associated with post-transplant quality of life in liver transplant recipients.

METHODS

Three hundred and eight liver transplant recipients were administered the Short Form 36 and a basic demographical questionnaire. Variables associated with post-transplant quality of life were studied in a multivariate regression analysis. Interaction terms were used to examine effect modification.

RESULTS

Male gender, longer pretransplant work hours and interaction term between work hours and male gender were independently associated with Physical Functioning. Work hours positively correlated with Role-Physical, while viral hepatitis and ascites were negatively associated with Role-Physical. Ascites and viral hepatitis were independently negatively associated with Bodily Pain. Encephalopathy, hepatocellular carcinoma and viral hepatitis were independently associated with General Health. Ascites was also negatively associated with Social Functioning, Role-Emotional, Bodily Pain, General Health and Vitality. Viral hepatitis was negatively correlated with Vitality and Mental Functioning.

CONCLUSIONS

Pretransplant variables such as ascites, encephalopathy, hepatocellular carcinoma, viral hepatitis, work hours, time unable to work and gender were significantly associated with post-transplant quality of life in liver transplant recipients. Interventions addressing these issues may be initiated to improve the post-transplant quality of life.

Healthy lifestyles and health-related quality of life among men living with HIV infection

Although healthy lifestyles are related to improved quality of life in the general population, little is known about the role of healthy lifestyles during HIV infection. The authors examined the relationships between health-promoting behaviors, risk behaviors, stress, and health-related quality of life (HRQOL) among 226 men with HIV infection who were attending three infectious disease clinics. As hypothesized, health-promoting behaviors were positively related and stress was negatively related with most of the HRQOL dimensions. Contrary to the hypothesis, tobacco use, recreational drug use, and unsafe sexual behaviors were not related to the HRQOL dimensions. Hazardous alcohol use was negatively associated with one HRQOL dimension--social functioning. The association of modifiable factors, such as health-promoting behaviors and stress, with HQROL offers opportunities for improving HIV-related health care. Relatively simple, straightforward changes in lifestyles such as eating well, remaining active, and avoiding stressful life events may result in improvements in HRQOL.

Patterns and predictors of physical functional disability at 5 to 10 years after heart transplantation

BACKGROUND

Researchers have not examined relationships between perception of physical functional disability and demographic, clinical, and psychological variables at 5 to 10 years after heart transplantation. Therefore, the purposes of this study were to describe physical functional disability over time and identify predictors of physical functional disability from 5 to 10 years after heart transplantation.

METHODS

The study enrolled 555 patients who were between 5 and 10 years post-heart transplant (age, 54 +/- 9 years; 78% male, 88% white, 79% married). Patients completed 6 instruments that measure physical functional disability and factors that may impact physical functional disability. Statistical analyses included calculation of frequencies, means +/- standard deviation (plotted over time), Pearson correlation coefficients, and multiple regression coupled with repeated measures.

RESULTS

Between 5 and 10 years after heart transplantation, physical functional disability was low, and 34% to 45% of patients reported having no functional disability. More physical functional disability was associated with having more symptoms, having depression/mood/negative affect and lower use of negative coping strategies, having more comorbidities and more specific comorbidities (e.g., more orthopedic problems and diabetes); higher New York Heart Association functional class; having more acute rejection, infection, or cardiac allograft vasculopathy; being female, older, less educated, and unemployed; higher body mass index; and more hospital readmissions (explaining 46% of variance [F = 84.75, p < 0.0001]).

CONCLUSIONS

Demographic, clinical, and psychological factors were significantly related to physical functional disability. Knowledge of these factors provides the basis for development of therapeutic plans of care.

Patterns and predictors of quality of life at 5 to 10 years after heart transplantation

BACKGROUND

Although studies have provided us with a cross-sectional analysis of long-term quality of life (QOL) after transplantation, relatively few longitudinal studies have been done that allow us to understand changes in QOL over time. The purposes of our study were to describe QOL over time and identify predictors of QOL longitudinally from 5 to 10 years after heart transplantation.

METHODS

All 555 subjects enrolled in this study completed booklets of questionnaires. These patients had a mean age of approximately 54 years (range 21 to 75 years) at time of transplant. Seventy-eight percent were men and 88% were white. Participants completed nine self-report QOL instruments for this study. Statistical analyses included frequencies, means +/- standard deviations (plotted over time), Pearson correlation coefficients and multiple regression coupled with repeated measures.

RESULTS

At 5 to 10 years after heart transplantation, recipients reported high levels of satisfaction with overall QOL and with health-related QOL, which was stable over the 5-year period. Predictors of satisfaction with overall QOL (that individually accounted for 1% variance or more) were primarily psychosocial variables (overall model explaining 71% of variance), whereas predictors of satisfaction with QOL related to health and functioning (that also explained > or =1% variance) included symptom distress and physical function, as well as psychosocial variables (overall model explaining 72% of variance).

CONCLUSIONS

At 5 to 10 years after heart transplantation, QOL remained positive and stable. Bio-psychosocial variables predicted satisfaction with overall QOL and health-related QOL. Understanding of these bio-psychosocial variables provides direction for the development of long-term therapeutic strategies after heart transplantation so that patients can have good post-transplant outcomes.

Satisfaction with heart transplantation

This research investigated patient satisfaction with heart transplantation (HT) 6 months after surgery. The authors explored whether HT patients would make the decision to have HT again and examined medical, psychosocial, and demographic factors associated with satisfaction or dissatisfaction in 257 HT recipients. Nonparametric statistics were used. Satisfaction with HT could be rated from 1 (not satisfied) to 10 (very satisfied). Eighty-seven percent of the patients were highly satisfied with HT 6 months after surgery (ratings of 8-10); 1% rated their satisfaction as low (1-3), and 12% rated it as moderate (4-7). Factors associated with less satisfaction with HT were: more symptom distress, greater disability, more stress, poor coping ability, feeling that the interventions of the HT team were not very helpful, less life satisfaction, and lower quality of life. Ninety-three percent indicated that they either definitely or probably would decide to have HT again; 7% responded "probably not" or "not sure." Factors associated with a negative perception of having another HT were: poor coping ability, less life satisfaction, lower quality of life, being male, and being married.

Predictors of quality of life at 5 to 6 years after heart transplantation

BACKGROUND

Only a few researchers have examined quality of life (QOL) outcomes more than 5 years after heart transplantation. Therefore, the purpose of this study was to describe QOL (overall, satisfaction with, and perceived importance); identify differences in QOL by age, sex, and race; and identify predictors of QOL at 5 to 6 years after heart transplantation.

METHODS

A nonrandom sample of 231 patients (60 years of age, 76% men, 90% white, 79% married, and fairly well educated) who were 5 to 6 years after heart transplantation were investigated. Patients completed 12 QOL instruments via self-report. Data analyses included descriptive statistics, chi2, independent t-tests, correlations, and stepwise multiple regression. Level of significance was set at 0.05.

RESULTS

Patient satisfaction with all areas of life was high at 5 to 6 years after heart transplantation. Similarly, patients believed that these same areas of life were very important. Yet areas of QOL with lower levels of satisfaction were identified. Patients who were > or =60 years were more satisfied with their QOL than patients <60 years. At 5 to 6 years after heart transplantation, almost 80% of variance in QOL was explained by psychological, physical, social, clinical, and demographic variables.

CONCLUSIONS

At 5 to 6 years after heart transplantation, patients were very satisfied with their QOL, although differences in level of satisfaction were identified by demographic variables, and areas of QOL with lower levels of satisfaction were identified. Understanding those variables that contribute to QOL in the long term after heart transplantation provides direction for assisting patients to improve their QOL.

Who Returns to Work After Heart Transplantation?

BACKGROUND

Detailed information regarding the work history of heart transplant patients is limited. Therefore, the work history and factors associated with return to work at 1 year after heart transplantation were examined in 237 heart transplant patients as part of a longitudinal quality-of-life study at two university medical centers. Patient characteristics were as follows: 81% male; 89% white; mean age 54 years (range 24 to 71); mean level of education 13 years; and 84% were married.

METHODS

Data were collected using the following instruments: Work History tool; Rating Question Form; Heart Transplant Stressor Scale; Quality of Life Index; Sickness Impact Profile; Jalowiec Coping Scale; Social Support Index; Heart Transplant Symptom Checklist; and Chart Review Form. Frequency distributions, chi-square, t-tests and stepwise regression were used to examine the work history of patients.

RESULTS

Pre-transplant, only 17% of patients were working as compared with 26% (61 of 237) working by 1 year after transplant (p = 0.003). Pre-transplant non-working patients (n = 197) were hospitalized more frequently, were more physically disabled, had more symptom distress, and rated their health as poorer. After heart transplant non-working patients (n = 176) had more rejection, infection and medical complications and more hospital days. Patients who were working either pre- or post-transplant were more likely to hold jobs that were less physically demanding. Factors significantly associated with return to work by 1 year after heart transplant were better functional ability, higher education, fewer endocrine problems, fewer acute rejection episodes and shorter heart transplant waiting time.

CONCLUSIONS

Clinical and demographic variables influence return to work after heart transplantation. Knowledge of these variables provides the health-care team with information to assist patients in securing gainful employment.

Patient Education and Health-related Quality of Life

The purpose of this study was to analyze the connections between patient education and health-related quality of life as an outcome variable. Data were collected among surgical hospital patients (n = 237) in Finland. On the basis of the results, there seems to be a positive relationship between received knowledge and health-related quality of life, and as such, the study produced knowledge about one quality indicator in nursing care. More research is needed to explore this connection in greater details.

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.
