Delirium in advanced cancer patients

Delirium in advanced cancer is often poorly identified and inappropriately managed. It is one of the most common causes for admission to clinical institutions and is the most frequently cited psychiatric disorder in terminal cancer. Diagnosis of delirium is defined as a disturbance of consciousness and attention with a change in cognition and/or perception. In addition, it develops suddenly and follows a fluctuating course and it is related to other causes, such as cancer, metabolic disorders or the effects of drugs. Delirium occurs in 26% to 44% of cancer patients admitted to hospital or hospice. Of all advanced cancer patients, over 80% eventually experience delirium in their final days. In advanced cancer, delirium is a multifactorial syndrome where opioids factor in almost 60% of episodes. Delirium in such patients, excluding terminal delirium, may be reversible in 50% of cases. Providing adequate end-of-life care for a patient with delirium is the main challenge. The family needs advice and it is important to create a relaxing environment for the patient. The primary therapeutic approach is to identify the reversible causes of delirium. Some therapeutic strategies have been shown to be effective: reduction or withdrawal of the psychoactive medication, opioid rotation, and hydration. Haloperidol is the most frequently used drug, and new neuroleptics such as risperidone or olanzapine are being tested with good results. Methylphenidate has been used for hypoactive delirium.

Education, implementation, and policy barriers to greater integration of palliative care: A literature review

Background: Early integration of palliative care into the management of patients with serious disease has the potential to both improve quality of life of patients and families and reduce healthcare costs. Despite these benefits, significant barriers exist in the United States to the early integration of palliative care in the disease trajectory of individuals with serious illness. Aim: To provide an overview of the barriers to more widespread palliative care integration in the United States. Design and data sources: A literature review using PubMed from 2005 to March 2015 augmented by primary data collected from 405 hospitals included in the Center to Advance Palliative Care’s National Palliative Care Registry for years 2012 and 2013. We use the World Health Organization’s Public Health Strategy for Palliative Care as a framework for analyzing barriers to palliative care integration. Results: We identified key barriers to palliative care integration across three World Health Organization domains: (1) education domain: lack of adequate education/training and perception of palliative care as end-of-life care; (2) implementation domain: inadequate size of palliative medicine–trained workforce, challenge of identifying patients appropriate for palliative care referral, and need for culture change across settings; (3) policy domain: fragmented healthcare system, need for greater funding for research, lack of adequate reimbursement for palliative care, and regulatory barriers. Conclusion: We describe the key policy and educational opportunities in the United States to address and potentially overcome the barriers to greater integration of palliative care into the healthcare of Americans with serious illness.

Cómo validar un instrumento de medida de la salud

Cada vez es mas necesario disponer de instrumentos de medida en el ambito de la salud que se puedan utilizar en la practica clinica e investigacion. Para garantizar la calidad de su medicion es imprescindible que los instrumentos sean sometidos a un proceso de validacion. Este proceso consiste en adaptar culturalmente un instrumento al medio donde se quiere administrar y comprobar sus caracteristicas psicometricas como: fiabilidad, validez, sensibilidad y factibilidad. Hay instrumentos de medida del ambito de la salud, disponibles en otros idiomas pero sin validar al espanol. Ademas la metodologia para validar un instrumento es poco conocida por profesionales sanitarios, lo que explica el uso indiscriminado de instrumentos solo adaptados o validados de manera poco consistente. El objetivo de esta revision es realizar una puesta al dia del proceso de validacion de un instrumento de medida de la salud y en que consiste de manera practica. La accesibilidad de instrumentos de evaluacion adaptados culturalmente y validados en distintos idiomas facilitara comparar resultados obtenidos con el mismo instrumento y desarrollar estudios internacionales en distintas culturas.

Barriers to the Development of Palliative Care in the Countries of Central and Eastern Europe and the Commonwealth of Independent States

During the years of communist rule in the countries of Central and Eastern Europe (CEE) and the Commonwealth of Independent States (CIS), there were few significant palliative care developments. Since the political changes of the 1990s, however, there has been a steady development of palliative care services in this region. In 2005, the European Association for Palliative Care Task Force for the Development of Palliative Care in Europe undertook a qualitative survey among boards of national associations to identify barriers to the development of palliative care in CEE and CIS. By July 2006, 44 of 52 (85%) European countries had responded to the survey, but we report here on the specific results from 22 of 27 (81%) countries in CEE and CIS. Data were analyzed thematically by geographic region and by the degree of development of palliative care in each country. Four significant barriers to the development of palliative care were identified: 1) financial and material resources; 2) problems relating to opioid availability; 3) lack of public awareness and government recognition of palliative care as a field of specialization; and 4) lack of palliative care education and training programs. Despite huge variations in the levels of provision across the countries of CEE and the CIS, data collected in the qualitative survey reveal that the development of palliative care in many countries continues to remain uneven, uncoordinated, and poorly integrated across wider health care systems, mainly as a result of inadequate investment and limited palliative care service capacity.

Towards integration of palliative care in patients with chronic heart failure and chronic obstructive pulmonary disease: A systematic literature review of European guidelines and pathways

BackgroundDespite the positive impact of Palliative Care (PC) on the quality of life for patients and their relatives, the implementation of PC in non-cancer health-care delivery in the EU seems scarcely addressed. The aim of this study is to assess guidelines/pathways for integrated PC in patients with advanced Chronic Heart Failure (CHF) and Chronic Obstructive Pulmonary Disease (COPD) in Europe via a systematic literature review.MethodsSearch results were screened by two reviewers. Eligible studies of adult patients with CHF or COPD published between 01/01/1995 and 31/12/2013 in Europe in 6 languages were included. Nine electronic databases were searched, 6 journals were hand-searched and citation tracking was also performed. For the analysis, a narrative synthesis was employed.ResultsThe search strategy revealed 26,256 studies without duplicates. From these, 19 studies were included in the review; 17 guidelines and 2 pathways. 18 out of 19 focused on suffering reduction interventions, 13/19 on a holistic approach and 15/19 on discussions of illness prognosis and limitations. The involvement of a PC team was mentioned in 13/19 studies, the assessment of the patients’ goals of care in 12/19 and the advance care planning in 11/19. Only 4/19 studies elaborated on aspects such as grief and bereavement care, 7/19 on treatment in the last hours of life and 8/19 on the continuation of goal adjustment.ConclusionThe results illustrate that there is a growing awareness for the importance of integrated PC in patients with advanced CHF or COPD. At the same time, however, they signal the need for the development of standardized strategies so that existing barriers are alleviated.

Barriers to the development of palliative care in Western Europe

The Eurobarometer Survey of the EAPC Task Force on the Development of Palliative Care in Europe is part of a programme of work to produce comprehensive information on the provision of palliative care across Europe. Aim: To identify barriers to the development of palliative care in Western Europe. Method: A qualitative survey was undertaken amongst boards of national associations, eliciting opinions on opportunities for, and barriers to, palliative care development. By July 2006, 44/52 (85%) European countries had responded to the survey; we report here on the results from 22/25 (88%) countries in Western Europe. Analysis: Data from the Eurobarometer Survey were analysed thematically by geographical region and by the degree of development of palliative care in each country. Results: From the data contained within the Eurobarometer, we identified six significant barriers to the development of palliative care in Western Europe: (i) lack of palliative care education and training programmes; (ii) lack of awareness and recognition of palliative care; (iii) limited availability of/knowledge about opioid analgesics; (iv) limited funding; (v) lack of coordination amongst services; and (vi) uneven palliative care coverage. Conclusion: Findings from the EAPC Eurobarometer Survey suggest that barriers to the development of palliative care in Western Europe may differ substantially from each other in both their scope and context and that some may be considered to be of greater significance than others. A number of common barriers to the development of the discipline do exist and much work still remains to be done in the identified areas. This paper provides a road map of which barriers need to be addressed.

Official certification of doctors working in palliative medicine in Europe: data from an EAPC study in 52 European countries.

There is an increasing move to recognize palliative medicine as an area of certificated specialization. Drawing on a survey of palliative care provision in the World Health Organization European region, an overview of palliative care specialization and accreditation practices was presented. Within an international survey to key experts in palliative care carried out in 2005, conducted in 52 countries, a question about the certification for palliative care professionals was included. Information was obtained for 43 of the 52 countries surveyed and all 43 countries (83%) provided data on certification. Palliative medicine has specialty status in just two European countries: Ireland and the UK. In five countries it is considered as a sub-specialty, for which a second certification is required: Poland, Romania, Slovakia and Germany and, recently, France. Some 10 other countries have started the process of certification for palliative medicine, in all cases opting for sub-specialty status that follows full recognition in an established specialty. Across countries there is disparity in the certification criteria followed and considerable variability in the demands that are made in order to achieve certification. Further studies are needed to focus in depth on palliative medicine certification and accreditation across Europe. Establishing uniform approaches to certification for palliative medicine in different European countries will contribute to wider take-up of specialty status and the improved recognition of palliative care as a discipline.

Screening for Constipation in Palliative Care Patients

INTRODUCTION The objective of this study was to establish screening criteria for constipation in palliative care and, subsequently, to determine data for diagnostic suspicion of constipation in a palliative care population. Also we investigate the incidence of fecal impaction in the same sample of palliative care patients. MATERIALS AND METHODS A descriptive, multicenter cross-sectional study was done. All patients in active care by a group of hospital and home palliative care teams were studied. A questionnaire on signs (frequency and consistency of stools) and symptoms (pain, discomfort, or a sensation of incomplete evacuation when having a bowel movement) of constipation in last weeks, and a verbal numerical scale (VNS) (0-10) on discomfort or difficulty with constipation was completed by the patients. The patients were asked about impaction in the last 3 months. RESULTS One hundred twenty patients from 21 palliative care teams were included; the majority of patients received opiates (66%) and also laxatives (60%). Bowel movement rate less than three stools per week was found in 13% of patients, stools harder than normal were experienced in 24% patients, and 33% exhibited pain, discomfort, or sensation of incomplete evacuation. Of the patients studied 13% had some signs of habitual constipation but they did not complain of symptoms, others (17%) had some discomfort in spite of not having signs of constipation. As screening criteria for constipation in palliative care we elected to include indistinct presence of constipation symptoms or constipation signs in recent weeks. A diagnosis of suspicion of constipation was established in almost 1 of 2 patients (48%) of our palliative care population. VNS with cutoff point of 3 or more of 10, showed a sensitivity of 0.70 and a specificity of 0.74 and positive predictive value (PPV) of 73% positive and negative predictive value (NPV) of 70%. In addition to these findings a considerable number of our palliative care patients (20%) reported episodes of fecal impaction in the last 3 months. CONCLUSION The screening for constipation in palliative care should be performed exploring subjective symptoms and other objective signs. A diagnosis of suspected constipation was found in almost half of the palliative care patients studied. A VNS of constipation did not produce good predictive values for the detection of constipation in our sample.

An International Consensus Definition of the Wish to Hasten Death and Its Related Factors

Background The desire for hastened death or wish to hasten death (WTHD) that is experienced by some patients with advanced illness is a complex phenomenon for which no widely accepted definition exists. This lack of a common conceptualization hinders understanding and cooperation between clinicians and researchers. The aim of this study was to develop an internationally agreed definition of the WTHD. Methods Following an exhaustive literature review, a modified nominal group process and an international, modified Delphi process were carried out. The nominal group served to produce a preliminary definition that was then subjected to a Delphi process in which 24 experts from 19 institutions from Europe, Canada and the USA participated. Delphi responses and comments were analysed using a pre-established strategy. Findings All 24 experts completed the three rounds of the Delphi process, and all the proposed statements achieved at least 79% agreement. Key concepts in the final definition include the WTHD as a reaction to suffering, the fact that such a wish is not always expressed spontaneously, and the need to distinguish the WTHD from the acceptance of impending death or from a wish to die naturally, although preferably soon. The proposed definition also makes reference to possible factors related to the WTHD. Conclusions This international consensus definition of the WTHD should make it easier for clinicians and researchers to share their knowledge. This would foster an improved understanding of the phenomenon and help in developing strategies for early therapeutic intervention.

Does palliative care education matter to medical students? The experience of attending an undergraduate course in palliative care

Background Palliative care (PC) education has become a priority in many European countries where PC is quickly developing. There remains, however, a lack of information on acceptability and medical students’ experiences in PC education. This kind of information is important because it could encourage universities to adapt their curricula appropriately to the demographic and societal necessity. Objective To explore medical students’ reactions to an optional PC course using their reflective written comments. Methods 316 medical students at the University of Navarra, over a period of 4 years, wrote evaluative comments regarding their experience and what they perceived as the courses contribution to their education. With these comments, a qualitative thematic analysis was carried out. Results With a response ratio of 90%, five main themes were identified: (1) The course helped medical students to become and act as doctors, (2) The benefits of having a holistic view of the patient and taking the family into account, (3) PC opens up a new a field of knowledge, (4) The course makes students think and reflect on their personal development and encourages them to deepen humanistic aspects of their practice, (5) The practical aspect is essential in PC learning. In addition, significantly, students used vigorous and positive expressions when writing about their experiences. Discussion The subject of PC turns out to be very important to students, who almost unanimously evaluated their experience positively and highlighted the benefits of attending a PC course. Students especially reported being surprised by the humane and holistic features of the course, and they found that what they learned in the course is applicable to all patients and prepares them to work better as doctors. Participants recommend the course for all undergraduate students as a core component of the curricula.
