Shared decision making in transplantation: how patients see their role in the decision process of accepting a donor liver

At the time of the organ offer for transplantation, donor-related risks such as disease transmission and graft failure are weighed against the patient's risk of remaining on the waiting list. The patient's commonly inactive role in decision making and the timing and extent of donor-specific risk information have been discussed in the medical literature. This is the first study revealing the opinions of liver patients on these issues. Forty patients listed for liver transplantation and 179 liver transplant patients participated in an anonymous questionnaire-based survey. The majority of the patients wanted to be informed about donor-related risks (59.8%-74.8%). The preferred timing for being informed about donor-related risks was the time of the organ offer for 53.3% of the patients. Among these patients, 79.8% wished to be involved in making the decision to accept or not accept a liver for transplantation, 10.6% wished to make the final decision alone, and only 9.6% did not want to be involved in the decision-making process. Implementing this knowledge through the standardization of the content, the manner of transfer, and the amount of information that we provide to our patients will improve opportunities for shared decision making at different time points during the transplant allocation process. This will enable us to provide the same opportunities and care to every patient on the waiting list.

Testing the McSad depression specific classification system in patients with somatic conditions: validity and performance

Background

Valuations of depression are useful to evaluate depression interventions offered to patients with chronic somatic conditions. The only classification system to describe depression developed specifically for valuation purposes is the McSad, but it has not been used among somatic patients. The aim of this study was to test the construct validity of the McSad among diabetes and cancer patients and then to compare the McSad to the commonly used EuroQol – 5 Dimensions (EQ-5D^TM) classification system. The comparison was expected to shed light on their capacity to reflect the range of depression states experienced by somatic patients.

Methods

Cross-sectional data were collected online from 114 diabetes and 195 cancer patients; additionally, 241 cancer patients completed part of the survey on paper. Correlational analyses were performed to test the construct validity. Specifically, we hypothesized high correlations of the McSad domains with depression (Center for Epidemiological Studies Depression Scale (CES-D) and the Patient Health Questionnaire (PHQ-9)). We also expected low/moderate correlations with self-esteem (Rosenberg Self-Esteem scale - RSE) and extraversion (Eysenck Personality Questionnaire Extraversion scale - EPQ-e). Multiple linear regression analyses were run so that the proportion of variance in depression scores (CES-D, PHQ-9) explained by the McSad could be compared to the proportion explained by the EQ-5D classification system.

Results

As expected, among all patients groups, we found moderate to high correlations for the McSad domains with the CES-D (.41 to .70) and the PHQ-9 (.52 to .76); we also found low to moderate correlations with the RSE (-.21 to .-48) and the EPQ-e (.18 to .31). Linear regression analyses showed that the McSad explained a greater proportion of variance in depression (CES-D, PHQ-9) (Diabetes: 73%, 82%; Cancer: 72%, 72%) than the EQ-5D classification system (Diabetes: 47%, 59%; Cancer: 51%, 47%).

Conclusions

Findings support the construct validity of the McSad among patients with somatic conditions and demonstrate that it performs better than the EQ-5D classification system to reflect the range of depression states. For future valuation purposes, the McSad classification system could therefore be recommended to describe depression as experienced by patients with a chronic medical condition.

Validation of the Dutch version of the transplant effects questionnaire in liver transplant recipients

Little is known about the extent to which transplant recipients face emotional problems with the receipt of a transplanted organ. The Transplant Effects Questionnaire (TxEQ) enables the quantification of these problems. This study evaluates the psychometric properties of the Dutch translation of the TxEQ (TxEQ-NL) in a group of liver transplant recipients. Confirmatory factor analyses of the TxEQ-NL revealed an adequate fit with the original version. However, four items showed factor loadings <.40. Internal consistency was acceptable (.66-.79). The small correlations between the TxEQ-NL and generic measures of psychological functioning indicated that the constructs measured are related but distinguishable. Therefore, the TxEQ-NL adds a new dimension to the measurement of psychological functioning of transplant recipients.

Perceptions on the effectiveness of treatment and the timeline of Buruli ulcer influence pre-hospital delay reported by healthy individuals

Background

Delay in seeking treatment at the hospital is a major challenge in current Buruli ulcer control; it is associated with severe sequelae and functional limitations. Choosing alternative treatment and psychological, social and practical factors appear to influence delay. Objectives were to determine potential predictors for pre-hospital delay with Leventhal's commonsense model of illness representations, and to explore whether the type of available dominant treatment modality influenced individuals' perceptions about BU, and therefore, influenced pre-hospital delay.

Methodology

130 healthy individuals aged >18 years, living in BU-endemic areas in Benin without any history of BU were included in this cross-sectional study. Sixty four participants from areas where surgery was the dominant treatment and sixty six participants from areas where antibiotic treatment was the dominant treatment modality were recruited. Using a semi-structured interview we measured illness perceptions (IPQ-R), knowledge about BU, background variables and estimated pre-hospital delay.

Principal Findings

The individual characteristics ‘effectiveness of treatment’ and ‘timeline acute-chronic’ showed the strongest association with pre-hospital delay. No differences were found between regions where surgery was the dominant treatment and regions where antibiotics were the dominant treatment modality.

Conclusions

Individual characteristics, not anticipated treatment modality appeared predictors of pre-hospital delay.

Delay in seeking treatment for Buruli ulcer (BU) is a major challenge in current BU control. Research to date shows that several factors relate to delay, including a lack of knowledge about BU and its treatment, beliefs in a supernatural cause of the disease, feelings of fear and worry regarding the treatment, fear of surgery, direct and indirect costs, social isolation as a consequence of unbearable costs to the patients' family, a lack of confidence in the treatment, and stigma. This study focused upon the relationship between Illness perceptions and pre-hospital delay by using the Illness Perceptions Model of Moss-Morris et al in a sample of healthy community members living in 3 endemic areas for Buruli ulcer in Benin. We found that a chronic timeline perspective on Buruli ulcer and a higher perceived effectiveness of the treatment were independently associated with pre-hospital delay. The available dominant treatment modality in endemic areas (surgery or antibiotics) did not influence pre-hospital delay, a finding contrary to the previous suggestion that a fear of surgery would be related to delay in presenting to the hospital. This study has identified several individual characteristics which can form the basis of future interventions.

Complementary and alternative medicine use of women with breast cancer: self-help CAM attracts other women than guided CAM therapies

OBJECTIVE

Examine stability of use of complementary and alternative medicine (CAM) of breast cancer patients, reasons for CAM use, and sociodemographic, clinical, and psychological predictors of CAM use.

METHODS

CAM use was assessed after adjuvant therapy and six months later. Following the CAM Healthcare Model, CAM use was divided into use of provider-directed (guided) and self-directed (self-help) CAM. Stability and reasons for CAM use were examined with McNemar's tests and descriptive statistics. Cross-sectional and longitudinal associations between predictors and CAM use were examined with univariate and multivariate logistical analyses.

RESULTS

Use of provider-directed and self-directed CAM was stable over time (N=176). Self-directed CAM was more often used to influence the course of cancer than provider-directed CAM. Both were used to influence well-being. Openness to experience predicted use of provider-directed CAM, while clinical distress predicted use of self-directed CAM, after adjusting for other predictors. Perceived control did not predict CAM use.

CONCLUSION

CAM use is stable over time. It is meaningful to distinguish provider-directed from self-directed CAM.

PRACTICE IMPLICATIONS

Providers are advised to plan a 'CAM-talk' before adjuvant therapy, and discuss patients' expectations about influence of CAM on the course of cancer. Distressed patients most likely need information about self-directed CAM.

The impact of low vision on activities of daily living, symptoms of depression, feelings of anxiety and social support in community-living older adults seeking vision rehabilitation services

PURPOSE

Previous studies showed that older persons with vision loss generally reported low levels of health-related quality of life, although study outcomes with respect to feelings of anxiety and social support were inconsistent. The objective of this study was to examine the impact of low vision on health-related quality of life, including feelings of anxiety and social support, among community-living older adults seeking vision rehabilitation services.

METHODS

Differences of activities of daily living (Groningen Activity Restriction Scale-GARS), symptoms of depression and feelings of anxiety (Hospital Anxiety and Depression Scales-HADS) and social support (Social Support Scale Interactions-SSL12-I) between 148 older persons ≥57 years with low vision and a reference population (N = 4,792) including eight patient groups with different chronic conditions were tested with Student's t tests.

RESULTS

Older persons with vision loss reported poorer levels of functioning with respect to activities of daily living, symptoms of depression and feelings of anxiety as compared to the general older population as well as compared to older patients with different chronic conditions. In contrast, older persons with vision loss reported higher levels of social support.

CONCLUSIONS

Vision loss has a substantial impact on activities of daily living, symptoms of depression and feelings of anxiety. Professionals working at vision rehabilitation services may improve their quality of care as they take such information into account in their intervention work.

The tenacious goal pursuit and flexible goal adjustment scales: a validation study

The flexible goal adjustment (FLEX) and tenacious goal pursuit (TEN) scales are used regularly in aging research. The current study examined their validity in a sample of 517 women (30-75 years) in multiple ways. Overall, the findings show that the scales do not clearly distinguish between FLEX and TEN. The direction in which the items were formulated was just as important as what was being measured. Moreover, face validity of the inversely phrased items in particular appeared to be weak. On the basis of these findings, the authors recommend a revision of the concept definitions as well as of the items.

Effect of adaptive abilities on utilities, direct or mediated by mental health?

Background

In cost-utility analyses gain in health can be measured using health state utilities. Health state utilities can be elicited from members of the public or from patients. Utilities given by patients tend to be higher than utilities given by members of the public. This difference is often suggested to be explained by adaptation, but this has not yet been investigated in patients. Here, we investigate if, besides health related quality of life (HRQL), persons' ability to adapt can explain health state utilities. Both the direct effect of persons' adaptive abilities on health state utilities and the indirect effect, where HRQL mediates the effect of ability to adapt, are examined.

Methods

In total 125 patients with Rheumatoid Arthritis were interviewed. Participants gave valuations of their own health on a visual analogue scale (VAS) and time trade-off (TTO). To estimate persons' ability to adapt, patients filled in questionnaires measuring Self-esteem, Mastery, and Optimism. Finally they completed the SF-36 measuring HRQL. Regression analyses were used to investigate the direct and mediated effect of ability to adapt on health state utilities.

Results

Persons' ability to adapt did not add considerably to the explanation of health state utilities above HRQL. In the TTO no additional variance was explained by adaptive abilities (Δ R² = .00, β = .02), in the VAS a minor proportion of the variance was explained by adaptive abilities (Δ R² = .05, β = .33). The effect of adaptation on health state utilities seems to be mediated by the mental health domain of quality of life.

Conclusions

Patients with stronger adaptive abilities, based on their optimism, mastery and self-esteem, may more easily enhance their mental health after being diagnosed with a chronic illness, which leads to higher health state utilities.

Positive psychology in cancer care: a story line resistant to evidence

Background

Aspinwall and Tedeschi (Ann Behav Med, 2010) summarize evidence they view as supporting links between positive psychological states, including sense of coherence (SOC) and optimism and health outcomes, and they refer to persistent assumptions that interfere with understanding how positive states predict health.

Purpose

We critically evaluate Aspinwall and Tedeschi’s assertions.

Methods

We examine evidence related to SOC and optimism in relation to physical health, and revisit proposed processes linking positive psychological states to health outcomes, particularly via the immune system in cancer.

Results

Aspinwall and Tedeschi’s assumptions regarding SOC and optimism are at odds with available evidence. Proposed pathways between positive psychological states and cancer outcomes are not supported by existing data. Aspinwall and Tedeschi’s portrayal of persistent interfering assumptions echoes a disregard of precedent in the broader positive psychology literature.

Conclusion

Positive psychology’s interpretations of the literature regarding positive psychological states and cancer outcomes represent a self-perpetuating story line without empirical support.

Invited commentary: personality as a causal factor in cancer risk and mortality--time to retire a hypothesis?

In this issue of the Journal, Nakaya et al. (Am J Epidemiol. 2010;172(4):377-385) report null findings from a large-scale prospective study of the prognostic value of 2 personality dimensions, neuroticism and extraversion, for cancer risk and mortality. The study stands out because of its exceptionally large sample size and its methodological strengths. The authors discuss the Nakaya et al. study in the context of persistent beliefs about the role of personality in cancer onset and survival despite a pattern of null findings in the literature, as well as the influence of extreme outlier findings from one investigator group that continue to be cited. They question whether it is time for the field to move on from considering a role for personality in cancer to more promising and modifiable factors.

Personal control over the cure of breast cancer: adaptiveness, underlying beliefs and correlates

OBJECTIVES

Although cognitive adaptation theory suggests that personal control acts as a stress buffer when facing adversity, maladaptive outcomes might occur when control is disconfirmed. The moderating effect of disappointing news on the adaptiveness of personal control over cure in women with breast cancer was examined and contrasted with the effect on the adaptiveness of general control over life. Additionally, the underlying beliefs and correlates of control over cure were explored.

METHODS

Women with newly diagnosed breast cancer were assessed after surgery (n=228). For a sub-sample (n=133) data before surgery and after the end of treatment were available as well. Data were collected through questionnaires and face-to-face interviews. The prescription of chemotherapy after surgery was used as an indicator of disappointing news.

RESULTS

A chemotherapy prescription neither enhances nor limits the adaptiveness of disease-specific or general control perceptions. Women reported that maintaining a positive attitude, accepting treatment and adopting a healthy life style gave them a sense of control over cure. Women with a strong sense of control over cure more often had invasive cancer, were younger and were best characterized by high optimism and strong sense of control over life.

CONCLUSIONS

The findings add to our understanding of exaggerated control perceptions in cancer patients treated with curative intent and do not give reason to assume that such perceptions should be altered because of potentially maladaptive effects. On the contrary, a strong sense of control over the cure of breast cancer seems to reflect the capacity to adapt.

Partner support and distress in women with breast cancer: The role of patients' awareness of support and level of mastery

The aim of the present study was to investigate the associations between partners' ways of providing support (both active engagement and protective buffering) and distress in women with breast cancer as a function of patients' awareness of the support received and their sense of mastery. These associations were investigated both cross-sectionally and longitudinally (i.e. changes in distress over time). At 3 months (T1) after diagnosis, women with breast cancer and their partners (n = 82 couples) were assessed regarding partners' supportive behaviour. Women also indicated their sense of mastery. At both 3 and 9 months (T2) after diagnosis, women reported their level of distress. Cross-sectional as well as longitudinal analyses showed that active engagement was unrelated to distress, regardless of patients' awareness of the support received and their feelings of mastery. In contrast, perceived protective buffering was found to be associated with more concurrent distress (i.e. cross-sectionally). Moreover, protective buffering that was reported by partners but remained unnoticed by patients was associated with higher levels of concurrent distress, but only for patients who were low in mastery. Over time, protective buffering that remained unnoticed by patients was associated with more distress, regardless of women's sense of mastery.

The structure of adversarial growth in a sample of cancer patients 8 years post-diagnosis: a revision of the SLQ-38

Stressful and traumatic events may trigger positive life changes, so-called adversarial growth. Despite growing interest in this topic, the structure and dimensionality of this concept has not been established. Recently, empirical reviews have suggested that the factors underlying this construct are highly related. Currently, the use of confirmatory factor analysis to test this hypothesis is advocated. Using data from cancer patients (n = 206), this study investigated the dimensionality of a Dutch translated version of the Silver Lining Questionnaire (SLQ-38). A 16-item SLQ (SLQ-16), with three subscales or first-order factors (enhanced personal relationships, changes in life philosophy and changes within the self) loading on a second-order general adversarial growth factor, was a good fitting model. In conclusion, the SLQ-16 may prove useful in the assessment of adversarial growth following illness.

More evidence that depressive symptoms predict mortality in COPD patients: is type D personality an alternative explanation?

Background/Purpose

The present study attempted to replicate our previous finding that depressive symptoms are a risk factor for mortality in stable chronic obstructive pulmonary disease (COPD), but in a different population with a different measure of depressive symptoms. We further investigated whether type D personality is associated with mortality in patients with COPD and whether it explains any relationship observed between depressive symptoms and mortality.

Methods

In 122 COPD patients, mean age 60.8 ± 10.3 years, 52% female, and mean forced expiratory volume in 1 s (FEV₁) 41.1 ± 17.6%pred, we assessed body mass index, post bronchodilator FEV₁, exercise capacity, depressive symptoms with the Hospital Anxiety and Depression Scale, and type D with the Type D Scale.

Results

In the 7 years follow-up, 48 (39%) deaths occurred. The median survival time was 5.3 years. Depressive symptoms (hazard ratio = 1.07, 95% confidence intervals = 1.00–1.14) were an independent risk factor for mortality. Type D was not associated with mortality.

Conclusions

We can rule out type D as an explanation for the relationship between depressive symptoms and mortality observed in this sample. However, ambiguity remains as to the interpretation of the value of depressive symptoms in predicting death.

The adaptive role of perceived control before and after cancer diagnosis: A prospective study

Cancer is generally considered a low-control situation. Stability of perceptions of control before and after cancer was examined, as well as the adaptive value of maintenance versus relinquishment of control in the psychological adjustment to cancer. This study, conducted in the northern Netherlands, was carried out in a prospective design with four assessment points (one pre-morbid and three post-morbid assessments) involving semi-structured interviews and self-report questionnaires. Ninety-nine newly diagnosed cancer patients all aged over 57 years completed all four assessment points. We found that perceptions of control declined before and after disease, possibly as a consequence of the diagnosis of cancer. Further, maintenance of control after cancer diagnosis was related to lower levels of psychological distress 6 and 12 months after diagnosis. These results suggest that maintenance of perceptions of control is beneficial to the psychological adjustment to cancer.

[Waiting times in breast disease clinics and psychological well-being: speedy care is better care]

OBJECTIVE

To examine the effect of diagnostic speed and the waiting time before surgery on the psychological well-being of patients in breast disease clinics.

DESIGN

Prospective cohort study

METHOD

Women with suspected breast cancer completed questionnaires about their psychological well-being before the first outpatient clinic visit (time T1: with malignancy (n = 149); without malignancy (n = 515)), shortly after diagnosis (T2: n = 96 and n = 432, respectively) and 2-3 months later (T3: with malignancy (n = 139)). Two months after the end of treatment (T4: with malignancy (n = 202)), women with breast cancer indicated which period they considered most stressful in retrospect. Diagnostic speed and the waiting time before surgery were categorized and the relation with well-being was examined. Analyses were controlled for age and cancer stage.

RESULTS

Although the period before diagnosis was experienced as stressful, diagnostic speed did not affect emotional well-being after a breast cancer diagnosis. However, a diagnosis that took a long time (> 2 weeks) did affect the emotional well-being of women who were not diagnosed with breast cancer. These women were worried and distressed for a longer period of time after diagnosis than women who received the favourable news sooner. The length of the waiting time before surgery did not affect the emotional well-being of patients thereafter: women who had surgery within two weeks were not worse or better off than women who had to wait longer. Yet, patients' emotional well-being did improve considerably after surgery, which indicates that short waiting times might shorten a period of psychological distress.

CONCLUSION

The results support a speedy diagnosis and surgery. There was no support for short waiting times having a negative psychological effect.

Socioeconomic status and the course of quality of life in older patients with coronary heart disease

Background

Previous research suggests that socioeconomic status (SES) might be related to the course of quality of life (QoL) in coronary heart disease (CHD) patients. The authors sought to determine whether there are differences in the course of QoL before and after the incidence of CHD among older persons of differing SES.

Method

Two hundred two CHD patients were followed up longitudinally using a community-based survey. Data on patients’ QoL were collected before the diagnosis and at three follow-up assessments.

Results

High SES patients reported better outcomes at the premorbid assessment with fewer depressive feelings and better physical functioning. In physical functioning, similar results were repeated 6 and 12 months after the diagnosis. Additionally, high SES patients showed better role and social functioning 1 year after CHD. A multivariate analysis of variance revealed differential longitudinal pathways in relation to SES in role, social, and physical functioning.

Conclusion

CHD modulates premorbid differences in depressive feelings. Conversely, high SES leads to better outcomes in all functional domains in the long-term after diagnosis. Postmorbid differences in physical functioning are not directly related to CHD, but rather the reestablishment of a premorbid situation. In contrast, socioeconomic inequalities in social and role functioning are a direct response to the impact of the disease.

The mediating role of perceived control on the relationship between socioeconomic status and functional changes in older patients with coronary heart disease

Using a prospective design, this study examines the mediating effect of perceived control in explaining the predictive role of socioeconomic status (SES) in long-term changes in functional status as a consequence of the occurrence of coronary heart disease (CHD). We followed 221 older CHD patients by using a community-based survey. We collected data on patients' functional status before the onset of disease and 1 year after the diagnosis. Multiple linear regressions show that SES predicts functional changes only in relation to physical functioning. Furthermore, self-efficacy, but not mastery, mediates the predictive role of SES in changes in physical functioning in CHD patients. Self-efficacy is the only aspect of control that mediates the relation between SES and changes in physical functioning. Our findings provide a basis for future interventions in disadvantaged groups of older persons and new theoretical models of recovery processes.
