What is the methodological rigour of palliative care research in long-term care facilities in Europe? A systematic review

Translating the Patient Dignity Inventory

Background:

The Patient Dignity Inventory (PDI) is based on an empirically-driven dignity model that has been developed and used for clinically assessing the various sources of dignity-related distress. In a recent review, it received the highest score as a useful instrument in both practice and research in palliative care. The PDI has been adapted to and validated for use in various countries, but not yet Sweden.

Aims:

To translate the PDI into Swedish, including cultural adaptation for clinical use.

Methods:

A multi-step process of translation, negotiated consensus, expert group discussion (n=7: four invited experts and three researchers) and cognitive interviewing (n=7: persons with palliative care needs).

Findings:

Discussion, by the expert reviewers, of both linguistic and cultural issues regarding the content and readability of the translated Swedish version resulted in revisions of items and response alternatives, focusing mainly on semantic, conceptual, and experiential equivalence. A pilot version for cognitive interviews was produced. The analysis of data showed that most of the items were judged to be relevant by the persons with palliative care needs.

Conclusion:

The process of translation and adaptation added clarity and consistency. The Swedish version of the PDI can be used in assessing dignity-related distress. The next step will be to test this Swedish version for psychometric properties in a larger group of patients with palliative care needs before use in research.

Development and evaluation of oral Cancer quality-of-life questionnaire (QOL-OC)

Background

In this study scales and items for the Oral Cancer Quality-of-life Questionnaire (QOL-OC) were designed and the instrument was evaluated.

Methods

The QOL-OC was developed and modified using the international definition of quality of life (QOL) promulgated by the European Organization for Research and Treatment of Cancer (EORTC) and analysis of the precedent measuring instruments. The contents of each item were determined in the context of the specific characteristics of oral cancer. Two hundred thirteen oral cancer patients were asked to complete both the EORTC core quality of life questionnaire (EORTC QLC-C30) and the QOL-OC. Data collected was used to conduct factor analysis, test-retest reliability, internal consistency, and construct validity.

Results

Questionnaire compliance was relatively high. Fourteen of the 213 subjects accepted the same tests after 24 to 48 h demonstrating a high test-retest reliability for all five scales. Overall internal consistency surpasses 0.8. The outcome of the factor analysis coincides substantially with our theoretical conception. Each item shows a higher correlation coefficient within its own scale than the others which indicates high construct validity.

Conclusions

QOL-OC demonstrates fairly good statistical reliability, validity, and feasibility. However, further tests and modification are needed to ensure its applicability to the quality-of-life assessment of Chinese oral cancer patients.

Integrating palliative care in long-term care facilities across Europe (PACE): protocol of a cluster randomized controlled trial of the 'PACE Steps to Success' intervention in seven countries

Background

Several studies have highlighted the need for improvement in palliative care delivered to older people long-term care facilities. However, the available evidence on how to improve palliative care in these settings is weak, especially in Europe. We describe the protocol of the PACE trial aimed to 1) evaluate the effectiveness and cost-effectiveness of the ‘PACE Steps to Success’ palliative care intervention for older people in long-term care facilities, and 2) assess the implementation process and identify facilitators and barriers for implementation in different countries.

Methods

We will conduct a multi-facility cluster randomised controlled trial in Belgium, Finland, Italy, the Netherlands, Poland, Switzerland and England. In total, 72 facilities will be randomized to receive the ‘Pace Steps to Success intervention’ or to ‘care as usual’. Primary outcome at resident level: quality of dying (CAD-EOLD); and at staff level: staff knowledge of palliative care (Palliative Care Survey). Secondary outcomes: resident’s quality of end-of-life care, staff self-efficacy, self-perceived educational needs, and opinions on palliative care. Economic outcomes: direct costs and quality-adjusted life years (QALYs).

Measurements are performed at baseline and after the intervention. For the resident-level outcomes, facilities report all deaths of residents in and outside the facilities over a previous four-month period and structured questionnaires are sent to (1) the administrator, (2) staff member most involved in care (3) treating general practitioner, and (4) a relative. For the staff-level outcomes, all staff who are working in the facilities are asked to complete a structured questionnaire. A process evaluation will run alongside the effectiveness evaluation in the intervention group using the RE-AIM framework.

Discussion

The lack of high quality trials in palliative care has been recognized throughout the field of palliative care research. This cross-national cluster RCT designed to evaluate the impact of the palliative care intervention for long-term care facilities ‘PACE Steps to Success’ in seven countries, will provide important evidence concerning the effectiveness as well as the preconditions for optimal implementation of palliative care in nursing homes, and this within different health care systems.

Palliative Care for Patients and Families With Parkinson's Disease

Parkinson's disease is the second most common neurodegenerative disease worldwide. There is widespread consensus that Parkinson patients, their carers, and clinicians involved in their care would benefit from a fully integrated, need-based provision of palliative care. However, the concept of palliative care in Parkinson's disease is still poorly defined and, consequently, poorly implemented into daily clinical practice. A particular challenge is the gradually progressive nature of Parkinson's disease-with insidiously increasing disability-making it challenging to clearly define the onset of palliative care needs for Parkinson patients. As people with Parkinson's disease are now living longer than in the past, future research needs to develop a more robust evidence-based approach to clarify the disease events associated with increased palliative care needs, and to examine these, prospectively, in an integrated palliative care service. The modern palliative care outlook, termed "simultaneous care,",is no longer restricted to the final stage of disease. It involves incorporating a continuity of care, effective management of the chronic-palliative interface, and a multidisciplinary network of professionals working both in the community and in specialized clinics, with active involvement of caregivers. Although promising, there is still a need to demonstrate the effectiveness of palliative care for patients with Parkinson's disease.

Clinical trials in palliative care: a systematic review of their methodological characteristics and of the quality of their reporting

Background

Over the past decades there has been a significant increase in the number of published clinical trials in palliative care. However, empirical evidence suggests that there are methodological problems in the design and conduct of studies, which raises questions about the validity and generalisability of the results and of the strength of the available evidence. We sought to evaluate the methodological characteristics and assess the quality of reporting of clinical trials in palliative care.

Methods

We performed a systematic review of published clinical trials assessing therapeutic interventions in palliative care. Trials were identified using MEDLINE (from its inception to February 2015). We assessed methodological characteristics and describe the quality of reporting using the Cochrane Risk of Bias tool.

Results

We retrieved 107 studies. The most common medical field studied was oncology, and 43.9% of trials evaluated pharmacological interventions. Symptom control and physical dimensions (e.g. intervention on pain, breathlessness, nausea) were the palliative care-specific issues most studied. We found under-reporting of key information in particular on random sequence generation, allocation concealment, and blinding.

Conclusions

While the number of clinical trials in palliative care has increased over time, methodological quality remains suboptimal. This compromises the quality of studies. Therefore, a greater effort is needed to enable the appropriate performance of future studies and increase the robustness of evidence-based medicine in this important field.

End-of-life expectations and experiences among nursing home patients and their relatives--a synthesis of qualitative studies

OBJECTIVE

Synthesize research about patients' and relatives' expectations and experiences on how doctors can improve end-of-life care in nursing homes.

METHODS

We systematically searched qualitative studies in English in seven databases (Medline, Embase, PsycINFO, CINAHL, Ageline, Cochrane Systematic Reviews and Cochrane Trials). We included 14 publications in the analysis with meta-ethnography.

RESULTS

Patients and families emphasized the importance of health personnel anticipating illness trajectories and recognizing the information and palliation needed. Family members who became proxy decision-makers reported uncertainty and distress when guidance from health personnel was lacking. They worried about staff shortage and emphasized doctor availability. Relatives and health personnel seldom recognized patients' ability to consent, and patients' preferences were not always recognized.

CONCLUSION

Nursing home patients and their relatives wanted doctors more involved in end-of-life care. They expected doctors to acknowledge their preferences and provide guidance and symptom relief.

PRACTICE IMPLICATIONS

High-quality end-of-life care in nursing homes relies on organization, funding and skilled staff, including available doctors who are able to recognize illness trajectories and perform individualized Advance Care Planning.
