Dyspnea and quality of life indicators in hospice patients and their caregivers

Caregiver Burden in Pulmonary Patients

Caregiving has become an increasingly important medical and social issue in recent decades. We performed a cross-sectional study on pulmonary patients and accompanying informal caregivers who were hospitalized in the chest disease ward of a tertiary center in Turkey between January 2020 and April 2021. Informal caregivers were asked to complete the Zarit Caregiver Burden Interview. A total of 141 inpatients (39% female, mean age: 76.8 ± 10.2 years) and their informal caregivers (77% female, mean age: 54 ± 11.9 years) were evaluated. The caregivers were classified as light to medium burden (group 1, burden score ≤40) and medium to heavy burden (group 2, burden score >40). The mean burden score was 35.7 ± 13.3 points. The number of female caregivers was higher in group 2 (p = 0.025). There was a positive correlation between the burden score and female gender (p = 0.002) and the number of chronic diseases of caregivers (p = 0.020). Statistical analysis revealed a negative correlation between the burden score and the level of education (r = > -0.174, p = 0.040). Caregiver burden is related to the characteristics of the caregiver rather than those of the patient being cared for. Female caregivers with lower education and more than one chronic disease perceive a higher caregiver burden.

Developing and Assessing the Effectiveness of a Nurse-Led Home-Based Educational Programme for Managing Breathlessness in Lung Cancer Patients. A Feasibility Study

Introduction: Breathlessness is the most common and refractory symptom in lung cancer patients. Even though various educational programmes have been developed, only a few were intended for implementation in the home setting for its management.

Aim: Feasibility of a study for implementing a nurse-led educational programme for breathlessness management of lung cancer patients at home.

Method: A randomized feasibility study was undertaken between February 2017 and October 2018. Patients were recruited through referral from oncologists from two oncology centers in Cyprus under certain inclusion and exclusion criteria. Patients were randomized in the intervention or control group via a computer programme, and their named family caregivers (f.c.) were allocated in the same group. Participants were not blinded to group assignment. The intervention consisted of a PowerPoint presentation and implementation of three non-pharmacological interventions. The control group received usual care. Patients were assessed for breathlessness, anxiety, and depression levels, whereas f.c. were assessed for anxiety, depression, and burden levels. F.c. also assessed patients' dyspnea level. The duration of the study process for both the intervention and control group was over a period of 4 weeks.

Results: Twenty-four patients and their f.c. (n = 24) were allocated equally in the intervention and control group. Five patients withdrew, and the final sample entered analysis was 19 patients and 19 family caregivers. In the intervention group n = 11 + 11, and in the control group n = 8 + 8. In the intervention group patients' breathlessness and anxiety levels showed improvement and their f.c.s in the anxiety and burden levels. Major consideration was the sample size and the recruitment of the patients by the referring oncologists. Attrition was minor during the study process. No harm was recorded by the participants of the study.

Conclusions: The study provided evidence of the feasibility of the implementation of the educational programme. For the future definitive study major consideration should be patients' recruitment method in order to achieve adequate sample size. Moreover, qualitative data should be collected in relation to the intervention and the involvement of f.c. The feasibility study was registered to the Cyprus Bioethics Committee with the registration number 2016/16. There was no funding of the study.

Missed opportunity? Worsening breathlessness as a harbinger of death: a cohort study

The aim of the study was to explore trajectories of breathlessness intensity by function and life-limiting illness diagnosis in the last 3 weeks of life in palliative care patients.

A prospective, consecutive cohort study obtained point-of-care data of patients of Silver Chain Hospice Care Service (Perth, Australia) over the period 2011–2014 (n=6801; 51 494 data-points). Breathlessness intensity (0–10 numerical rating scale) and physical function (Australia-modified Karnofsky Performance Status (AKPS)) were measured at each visit. Time was anchored at death. Breathlessness trajectory was analysed by physical function and diagnosis using mixed effects regression.

Mean±sdage was 71.5±15.1 years and 55.2% were male, most with cancer. The last recorded AKPS was >40 for 26.8%. Breathlessness was worst in people with cardiorespiratory disease and AKPS >40, and breathlessness in the last week of life increased most in this group (adjusted mean 2.92versusall others 1.51; p=0.0001). The only significant interaction was with diagnosis and function in the last week of life (p<0.0001).

Breathlessness is more intense and increases more in people with better function and cardiorespiratory disease immediately before death. Whether there are reversible causes for these people should be explored prospectively. Omitting function from previous population estimates may have overestimated breathlessness intensity for many patients in the days preceding death.

Psychometric properties of carer-reported outcome measures in palliative care: A systematic review

BACKGROUND

Informal carers face many challenges in caring for patients with palliative care needs. Selecting suitable valid and reliable outcome measures to determine the impact of caring and carers' outcomes is a common problem.

AIM

To identify outcome measures used for informal carers looking after patients with palliative care needs, and to evaluate the measures' psychometric properties.

DESIGN

A systematic review was conducted. The studies identified were evaluated by independent reviewers (C.T.J.M., M.B., M.P.). Data regarding study characteristics and psychometric properties of the measures were extracted and evaluated. Good psychometric properties indicate a high-quality measure.

DATA SOURCES

The search was conducted, unrestricted to publication year, in the following electronic databases: Applied Social Sciences Index and Abstracts, Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library, EMBASE, PubMed, PsycINFO, Social Sciences Citation Index and Sociological Abstracts.

RESULTS

Our systematic search revealed 4505 potential relevant studies, of which 112 studies met the inclusion criteria using 38 carer measures for informal carers of patients with palliative care needs. Psychometric properties were reported in only 46% (n = 52) of the studies, in relation to 24 measures. Where psychometric data were reported, the focus was mainly on internal consistency (n = 45, 87%), construct validity (n = 27, 52%) and/or reliability (n = 14, 27%). Of these, 24 measures, only four (17%) had been formally validated in informal carers in palliative care.

CONCLUSION

A broad range of outcome measures have been used for informal carers of patients with palliative care needs. Little formal psychometric testing has been undertaken. Furthermore, development and refinement of measures in this field is required.

Informal caregiving of hospice patients

BACKGROUND

Informal caregivers play a critical role in the provision of care to hospice patients. The care they provide often impacts their physical and psychological well-being.

OBJECTIVE

This study synthesized 58 articles pertaining to informal hospice caregiving, focusing on caregivers' satisfaction with hospice services, the physical and psychological well-being of caregivers, the predictors of caregivers' well-being, the direct impact of hospice services on caregivers, and the effectiveness of targeted interventions for hospice caregivers.

METHOD

A systematic literature review of journal articles published between 1985 and 2012 was conducted.

RESULTS

The studies reviewed found hospice caregivers to experience clinically significant levels of anxiety, depression, and stress; however, results for caregiver burden and quality of life were mixed. Caregivers' perceptions regarding the meaningfulness of care as well as their levels of social support were associated with enhanced psychological outcomes.

CONCLUSIONS

Beyond satisfaction with hospice services, the direct impact of standard hospice care on caregivers remains uncertain. Caregiver intervention studies have demonstrated promising outcomes signifying a need for additional investigations into hospice-specific interventions that improve caregiver outcomes. Additional research and resources are needed to assist hospice caregivers, with the ultimate goal of minimizing their psychiatric and physical morbidity and enhancing their caregiving and subsequent bereavement processes.

Comparing unmet needs between community-based palliative care patients with heart failure and patients with cancer

BACKGROUND

As the role of palliative care (PC) has yet to be clearly defined in patients with heart failure (HF), such patients may face barriers regarding PC referral. In order to maximally meet the needs of HF patients, it is necessary to understand how they compare to the classic PC population: patients with cancer.

OBJECTIVE

To characterize the unresolved symptom and treatment needs with which patients with HF and those with cancer present to PC.

METHODS

We used data from the Palliative Care Research Registry (PCRR), a repository of quality improvement data from three community-based PC organizations. We abstracted first PC visit data from the PCRR for patients with primary diagnoses of HF or cancer seen between 2008 and 2012. We assessed the association of primary diagnosis (i.e., HF or cancer) on three outcomes: unresolved symptoms, treatment gaps, and a composite indicator of symptom control and quality of life. Analyses included descriptive statistics and multivariate Poisson regression.

RESULTS

Our analytic sample comprised 334 patients with HF and 697 patients with cancer, the majority of whom were white and male. Compared to patients with cancer, patients with HF presented with fewer unresolved symptoms, both overall and at moderate/severe distress levels. Patients with HF more commonly reported moderately/severely distressful dyspnea (25% versus 18%, p=0.02), and more commonly experienced dyspnea-related treatment gaps (17% versus 8%, p<0.001).

CONCLUSIONS

Patients with HF possess care needs that are squarely within the purview of PC. Future work is needed to delineate how PC referral policies should be refined to optimize PC access for patients with HF.

Provider approaches to palliative dyspnea assessment: implications for informatics-based clinical tools

AIM

To understand provider practices around dyspnea assessment to inform the development of an electronic medical record (EMR)-based dyspnea assessment module in an inpatient palliative care consultation template.

DESIGN

Qualitative analysis of palliative care provider interviews.

RESULTS

Three themes emerged: (1) integration of patient self-report of breathlessness with a clinical observation of dyspnea; (2) identification of patients for dyspnea assessment based on perceived patient need; and (3) variability in preferences for and use of existing severity scales for dyspnea.

CONCLUSIONS

The assessment approaches described by providers underscore the challenge of developing an informatics tool that supports the natural clinical experience and facilitates standardized care. The complexity of the dyspnea assessment process and variation in provider practices necessitate a level of flexibility and choice to be built into a computer-based tool.

Do the trajectories of dyspnea differ in prevalence and intensity by diagnosis at the end of life? A consecutive cohort study

CONTEXT

Breathlessness reportedly worsens as death approaches for many people, but the differences in intensity and time course between underlying causes are not well described.

OBJECTIVES

To determine differences in the intensity of breathlessness by diagnosis over time as death approaches in a consecutive cohort seen by a specialist palliative care service.

METHODS

Patients referred to Silver Chain Hospice Care Service over a period of four years (January 2004 to December 2007) had dyspnea evaluated at every clinical encounter until death. A numeric rating scale (NRS) was used to measure the intensity. Patients were categorized into five clusters (lung cancer, secondary cancer to lung, heart failure, end-stage pulmonary disease, and no identifiable cardiorespiratory cause) at three time points (60-53 [T(3)], 30-23 [T(2)], and 7-0 [T(1)] days before death [T(0)]). Group differences were assessed using analysis of variance. Joinpoint regression models defined significant changes in mean breathlessness intensity.

RESULTS

For 5,862 patients, data were collected an average of 20 times (median: 13; 116,982 data points) for an average of 86 days (median: 48). Breathlessness was significantly higher at all three time points in people with noncancer diagnoses. Breathlessness increased significantly at days 10 and 3 before death for people with cancer (P<0.001 for both), but remained unchanged, albeit significantly higher for patients with noncancer diagnoses. In the three months leading to death, the prevalence of "no breathlessness" decreased from 50% to 35%, and the proportion of patients with severe breathlessness (>7 out of 10) increased from 10% to 26%.

CONCLUSION

Prevalence of breathlessness increases rapidly at life's end, especially for people with primary lung cancer; the levels of breathlessness became close to those experienced by people with noncancer diagnoses despite symptom control measures.

Does palliative home oxygen improve dyspnoea? A consecutive cohort study

Palliative oxygen for refractory dyspnoea is frequently prescribed, even when the criteria for long-term home oxygen (based on survival, rather than the symptomatic relief of breathlessness) are not met. Little is known about how palliative home oxygen affects symptomatic breathlessness. A 4-year consecutive cohort from a regional community palliative care service in Western Australia was used to compare baseline breathlessness before oxygen therapy with dyspnoea sub-scales on the symptom assessment scores (SAS; 0-10) 1 and 2 weeks after the introduction of oxygen. Demographic and clinical characteristics of people who responded were included in a multi-variable logistic regression model. Of the study population (n = 5862), 21.1% (n = 1239) were prescribed oxygen of whom 413 had before and after data that could be included in this analysis. The mean breathlessness before home oxygen was 5.3 (SD 2.5; median 5; range 0-10). There were no significant differences overall at 1 or 2 weeks (P = 0.28) nor for any diagnostic sub-groups. One hundred and fifty people (of 413) had more than a 20% improvement in mean dyspnoea scores. In multi-factor analysis, neither the underlying diagnosis causing breathlessness nor the demographic factors predicted responders at 1 week. Oxygen prescribed on the basis of breathlessness alone across a large population predominantly with cancer does not improve breathlessness for the majority of people. Prospective randomised trials in people with cancer and non-cancer are needed to determine whether oxygen can reduce the progression of breathlessness compared to a control arm.

The impact of symptoms, coping capacity, and social support on quality of life experience over time in patients with lung cancer

The aims of the study were to investigate lung cancer patients' quality of life (QoL) over time in a palliative setting and to determine how QoL is influenced by symptoms, coping capacity, and social support. One hundred and five consecutive patients with incurable lung cancer were included. A comprehensive set of questionnaires was used at baseline, including the Assessment of Quality of Life at the End of Life, Cancer Dyspnea Scale, Visual Analog Scale of Dyspnea, Hospital Anxiety and Depression scale, Sense of Coherence Questionnaire, and Social Support Survey, of which the first four were used also at three, six, nine, and 12 months. Dyspnea, depression, and global QoL deteriorated over time. Performance status, anxiety, depression, components of dyspnea, pain, and the meaningfulness component of coping capacity correlated with global QoL at all, or all but one follow-up measurements. In a multivariate analysis with global QoL as the dependent variable, depression was a significant predictor at four out of five assessments, whereas coping capacity, anxiety, performance status, pain, and social support entered the model at one or two assessments. Emotional distress and coping capacity influence QoL and might be targets for intervention in palliative care.

Quality of life among Norwegians with chronic mental health problems living in the community versus the general population

We used the Quality of Life Scale to assess quality of life among 107 Norwegians with chronic mental health problems (MHP) from the community health care system versus 1893 general population adults. The groups differed in quality of life, including broader life domains. Age and quality of life were more strongly positively correlated in the MHP group than in the general population. Mental symptoms (measured by the Symptom Checklist-90 Revised) and quality of life were strongly negatively correlated in the MHP group. Services for people with chronic MHP should focus on enhancing quality of life and on its role as an outcome variable.

Spiritual needs of persons with advanced cancer

Spiritual needs, spiritual distress, and spiritual well-being of patients with terminal illnesses can affect their quality of life. The spiritual needs of patients with advanced cancer have not been widely studied. This study assessed the spiritual needs of 90 patients with advanced cancer who were newly admitted to hospice home care. They completed a demographic data form and the Spiritual Needs Inventory shortly after hospice admission. Scores could range from a low of 17 to a high of 85; study scores were 23 to 83. Results showed great variability in spiritual needs. Being with family was the most frequently cited need (80%), and 50% cited prayer as frequently or always a need. The most frequently cited unmet need was attending religious services. Results suggest the importance of a focus on the spiritual more than the religious in providing care to patients at the end of life.
