Self-Perceived Burden to Others: Patient and Family Caregiver Correlates

Aims

To provide further evidence about the prevalence and correlates of the sense of “self-perceived burden” (SPB) to others, and to examine its association with caregiver reports of burden.

Methods

The participants were 65 patients with advanced cancer and their family caregivers. Patients completed measures of SPB and family members completed a caregiver burden scale.

Results

SPB was experienced at minimal to mild levels by 35% of patients, and at moderate to extreme levels by another 28%. It was correlated with some physical symptoms, but more frequently with psychological symptoms. The family members of patients who reported that SPB was a significant problem had higher scores on the caregiver burden scale than family members of other patients (p=0.048), although the overall correlation was modest.

Conclusions

SPB is a common and distressing concern for many patients receiving palliative care and is associated with a number of other distressing concerns.

Demoralization Syndrome — a Relevant Psychiatric Diagnosis for Palliative Care

Hopelessness, loss of meaning, and existential distress are proposed as the core features of the diagnostic category of demoralization syndrome. This syndrome can be differentiated from depression and is recognizable in palliative care settings. It is associated with chronic medical illness, disability, bodily disfigurement, fear of loss of dignity, social isolation, and — where there is a subjective sense of incompetence — feelings of greater dependency on others or the perception of being a burden. Because of the sense of impotence or helplessness, those with the syndrome predictably progress to a desire to die or to commit suicide. A treatment approach is described which has the potential to alleviate the distress caused by this syndrome. Overall, demoralization syndrome has satisfactory face, descriptive, predictive, construct, and divergent validity, suggesting its utility as a diagnostic category in palliative care.

Burden to others and the terminally ill

Studies of patients who are terminally ill consistently identify strong associations between "sense of burden to others" and marked end-of-life distress. However, little research has addressed the issue of burden to others among patients nearing death. The aim of this study was to carefully examine "burden to others" and clarify its relationship with various psychosocial, physical, and existential issues arising in patients who are terminally ill. A cohort of 211 patients with end-stage cancer was assessed, using an assortment of validated psychometrics to document psychosocial, physical, and existential aspects of their end-of-life experience. This included an assessment of their sense of "burden to others." Forty percent of participants indicated a negligible sense of burden to others, scoring within the lowest quarter on an ordinal measure of "burden to others;" 25% scored within the second lowest quarter; 12% within the third quarter; and 23% within the highest or most severe range. The most highly correlated variables with "sense of burden to others" included depression (r=0.460; df=201, P<0.0001), hopelessness (r=0.420; df=199, P<0.0001), and outlook (r=0.362; df=200, P<0.0001). Four variables emerged in a multiple regression analysis predicting burden to others, including hopelessness, current quality of life, depression, and level of fatigue [R(2) adj=0.32, F(6,174)=13.76, P<0.0001]. There was no association between sense of burden to others and actual degree of physical dependency. Feeling a sense of burden to others is common among dying patients. Although 40% of the sample reported little in the way of sense of burden to others, the remainder endorsed higher degrees of burden-related distress, with 23% scoring within the most severe range. The lack of association between "sense of burden to others" and the degree of physical dependency suggests this perception is largely mediated through psychological and existential considerations. Strategies that target meaning and purpose, depression, and level of fatigue could lessen this source of distress and enhance quality, dignity-conserving care.

A review of psychosocial aspects of motor neurone disease

Motor neurone disease (MND) is an illness involving the progressive degeneration of upper and lower motor neurones. There is no known cause or cure. The physical aspects of MND frequently receive the majority of attention, with psychosocial aspects accorded secondary importance. We undertook a comprehensive search of the available literature published between 1966 and 2006 on the psychosocial aspects of MND, including quality of life (QoL), depression, social support, life sustaining treatment (LST), coping, spirituality and current practice. The literature identified that QoL correlated more strongly with measures of suffering, social support and hopelessness than with the physical state of the patient. Depression is relatively common (prevalence rates up to 50%), as are other forms of psychological distress in the MND population, and is not associated with illness severity and functional status. Depression strongly correlates with QoL. Social support is often limited for MND patients and this also influences QoL. Hope and hopelessness are important issues for MND patients with hopelessness contributing significantly to suffering and, for some, a desire for hastened death. Choices and decisions about life sustaining treatments pose a burden for patients and carers. Despite the physical and emotional suffering associated with MND, a significant number cope well and find positive meaning in life. Many patients opting for life sustaining treatment report a satisfactory QoL. In conclusion, psychosocial aspects of life are important for patients with MND. Depression and other expressions of distress require recognition and treatment. Issues of hope, spirituality and life and death also require attention in clinical practice. Although guidelines exist to direct physicians to attend to the physical care, there is a distinct lack of guidance to attend to the psychological state of the MND patient.

Feeling like a burden to others: a systematic review focusing on the end of life

Research into the burden of illness has focused predominantly on family caregivers, with little consideration of the other side of the caregiving relationship-care recipients' perspectives on having become a 'burden to others'. However, there is now a small but growing body of evidence to suggest that worry about creating burden to others is a common and troubling concern for people who are nearing the end of their lives. This concern is referred to as 'self-perceived burden'. The present study provides a systematic review of the literature, addressing self-perceived burden at the end of life. Using standard methods, literature was searched for relevant studies in palliative care and related fields. The review revealed that self-perceived burden is reported as a significant problem by 19- 65% of terminally ill patients. It is correlated with loss of dignity, suffering, and a 'bad death'. Self-perceived burden has also been identified as a relevant factor in death-hastening acts among patients with life-threatening illness, as well as in clinical decisions, such as the choice of place of care at the end of life, advance directives, and acceptance of treatment. Given the unique challenges faced by patients with advanced disease and their families, there is a need for further investigation into this under-researched area.

A Burden to Others: A Common Source of Distress for the Terminally Ill

Recent research into the desire for death among people with terminal illness has begun to recognize the importance of "feeling oneself a burden to others" as a factor in suicidal behaviour. In this study, 69 patients with advanced cancer underwent semi-structured interviews. The sense of self-perceived burden was found to be a common experience, reported by 39.1% of participants as a minimal or mild concern and by 38% as a moderate to extreme concern. The sense of burden showed a low correlation with physical symptoms (r = 0.02-0.24) and higher correlations with psychological problems (r = 0.35-0.39) and existential issues (r = 0.45-0.49). Comparisons of participants with high or low levels of self-perceived burden showed the importance of this factor for overall quality of life. In summary, self-perceived burden is an important but underestimated dimension of social cognition in the medically ill.
