Effects of opioids and sedatives on survival in an Australian inpatient palliative care population

Abstract

Aggregating single patient (n-of-1) trials in populations where recruitment and retention was difficult: the case of palliative care.

Randomized controlled trials (RCTs) are the gold standard for evaluating new interventions. Different RCT designs apply depending on the patient population, clinical setting, and intervention being evaluated. A design that may help to generate evidence in some clinical areas where recruitment is a challenge is aggregated n-of-1 trials. N-of-1 trials are randomized, double-blind, and multiple crossover comparisons of an intervention and a control treatment. Methodologically robust n-of-1 trials provide an objective means of testing the effectiveness of treatments within individual participants. Aggregation of multiple cycle identically conducted n-of-1 trials yield a population estimate of effect, which potentially commensurate with that derived from other RCT designs. Trial participants contribute data for both intervention and control treatments creating matched data sets while using generally smaller sample sizes than conventional RCT trials. Careful choice of symptoms and medications are required for n-of-1 trials to be feasible. A validated and reliable outcome measure sensitive to change is still required. This article reviews the utility and limitations of aggregated n-of-1 trials to gather evidence in populations where conducting formal RCTs is difficult because of the low prevalence of the underlying condition or the clinical condition making recruitment and retention difficult. The article examines a proposed palliative care trial as a test case.

The Troubles of Telling Managing Communication About the End of Life

Communication about palliative care represents one of the most difficult interpersonal aspects of medicine. Delivering the “terminal” diagnosis has traditionally been the focus of research, yet transitions to specialist palliative care are equally critical clinical moments. Here we focus on 20 medical specialists’ strategies for engaging patients around referral to specialist palliative care. Our aim was to develop an understanding of the logics that underpin their communication strategies when negotiating this transition. We draw on qualitative interviews to explore their accounts of deciding whether and when to engage in referral discussions; the role of uncertainty and the need for hope in shaping communication; and their perceptions of how patient biographies might shape their approaches to, and communication about, the end of life. On the basis of our analysis, we argue that communication is embedded in social relations of hope, justice, and uncertainty, as well as being shaped by patient biographies.

Neuropathic pain: are we out of the woods yet?

Patients suffering from neuropathic pain continue to pose challenges in clinical practice. This descriptive review discusses the continuing debate on the definition and concerns about increasing incidence of neuropathic pain. The clinical features of neuropathic pain are outlined, and the current understanding of the possible mechanisms of neuropathic pain is highlighted. Current management strategies are reviewed, and future advances in our understanding of the mechanisms, accurate clinical diagnosis and more effective treatment strategies are eagerly awaited.

Intranasal sufentanil for cancer-associated breakthrough pain

The objective of this study was to demonstrate the efficacy, safety and patient acceptability of the use of intranasal sufentanil for cancer-associated breakthrough pain. This was a prospective, open label, observational study of patients in three inpatient palliative care units in Australia. Patients on opioids with cancer-associated breakthrough pain and clinical evidence of opioid responsiveness to their breakthrough pain were given intranasal (IN) Sufentanil via a GO Medical™ patient controlled IN analgesia device. The main outcome measures were pain scores, need to revert to previous breakthrough opioid after 30 min, number of patients who chose to continue using IN sufentanil, and adverse effects. There were 64 episodes of use of IN sufentanil for breakthrough pain in 30 patients. There was a significant reduction in pain scores at 15 (P < 0.0001) and 30 min (P < 0.0001). In only 4/64 (6%) episodes of breakthrough pain did the participants choose to revert to their prestudy breakthrough medication. Twenty-three patients (77%) rated IN sufentanil as better than their prestudy breakthrough medication. The incidence of adverse effects was low and most were mild. Our study showed that IN sufentanil can provide relatively rapid onset, intense but relatively short lasting analgesia and in the palliative care setting it is an effective, practical, and safe option for breakthrough pain.

Specialists' experiences and perspectives on the timing of referral to palliative care: a qualitative study

BACKGROUND Specialist referral practices regarding palliative care are variable and their decision-making practices regarding timing and communication remains an under-researched issue. More effective referral practices have been shown to enhance patient and carer experiences at the end of life, reduce the burden on pre-palliative care services, and even extend life expectancy in some cases. OBJECTIVE The aim of this study was to examine the logics underpinning the timing of referral to palliative care according to a range of medical specialists in a regional center on the east coast of Australia, in order to facilitate improvements in referral practices. METHODS We conducted semi-structured, qualitative interviews with 20 medical specialists and carried out a thematic analysis of the interview data, utilising the framework analysis approach and NVivo 9 software. Key themes were tested for rigour through inter-rater reliability. RESULTS The major themes identified within this analysis of the interviews were: a) strategies for preparing for palliative care and the importance of planning timely referrals; b) perception of inter-professional variation and reasons for delayed or difficult referrals; and c) the importance of inter-specialty communication and cross-disciplinary dialogue. CONCLUSIONS Significant barriers exist to the timely referral to palliative care, and, in order to improve patient and care quality of life and lessen clinical difficulties, further work is needed to develop streamlined practices that are sensitive to specialty needs and patient desires.

Prospective audit of short-term concurrent ketamine, opioid and anti-inflammatory ('triple-agent') therapy for episodes of acute on chronic pain.

Aim:  This prospective audit was undertaken in order to document the analgesic response and adverse effects of concurrent short‐term (‘burst’) triple‐agent analgesic (ketamine, an opioid and an anti‐inflammatory agent – either steroidal or non‐steroidal) administration, for episodes of acute on chronic pain. The clinical hypothesis in this study is that better pain control may be obtained by simultaneous multiple target receptor blockade.

A discourse analysis of difficult clinical situations in relation to nutrition and hydration during end of life care

AIM AND OBJECTIVES The following discussion builds upon a previous publication that reported on the perceptions and discourses of palliative care nurses and doctors in relation to nutrition and hydration at the end of life. The aim of this paper is to report the discourses of nurses and doctors in relation to the challenges they faced when managing the care of patients with severe brain injury vs. the clearer cut situations when caring for terminally ill patients with cancer. The objectives of the study were to: explore the tensions in the discourses during end of life care, explore the challenges regarding nutrition and hydration at the end of life. BACKGROUND The decision to withdraw life support seems to be made more readily than the decision to withdraw nutrition and hydration at the end of life. The abatement of nutrition and hydration during the terminal phase of life is a controversial issue for a range reasons. Indeed, whilst it is accepted practice in the palliative care setting, nurses and doctors often struggle with the idea. DESIGN The design for this study used discourse analysis framed by a post structural framework. METHOD Focus groups were conducted with nurses working in palliative care units. Single interviews were conducted with doctors from a tertiary palliative care unit. RESULTS The findings revealed contesting discourses involving quality of life and the prolongation of life. CONCLUSIONS The provision of food and fluid has profound emotional and social meanings for patients and families. The study reported here examined these issues with health professionals. The findings point to the challenges and tensions faced by health professionals in relation to decision making and medical hydration during end of life care. The concern is that tensions arise when decisions need to be made and how best to make these. The contesting discourses for nurses and doctors when nutrition and hydration is ceased involve maintaining quality of life vs. the prolongation of life. RELEVANCE TO CLINICAL PRACTICE Medical and nursing staff have different attitudes and beliefs towards end of life care. Tensions arise when decisions need to be made based on quality of life or prolongation of life. The successful merging of curative and palliative care is not without challenges. There has been little exploration of this situation.

Families and the transition to specialist palliative care

Abstract Families play important roles in transitions to end-of-life care, yet we know little about the social relations between doctors and families at the point of referral to specialist palliative care. In this study, we explore how medical specialists negotiated the transition to specialist palliative care with families. Drawing on data from 20 qualitative interviews, we examine data accounts about the roles of family members in discussions with clinical specialists about palliative care, and how families shape interpersonal dynamics. Our results indicate that families fulfil important ‘functions’ and ‘roles’ in these delicate and emotionally laden conversations. Specialists’ accounts articulated referral processes as distinctly relational moments, with families viewed as potential ‘resources’ but also as ‘complications’, in attempts to encourage the ‘smooth’ transition to end-of-life care. On the basis of these results, we argue that further attention should be paid to the centrality of families in key moments in care (and communication therein) and how they may be utilised, managed and experienced by a range of health professionals.

Death and dying in Australia: perceptions of a Sudanese community

AIMS The aims of this study were to obtain information to support Palliative Care healthcare workers to meet the needs of the Sudanese population in death, dying, and bereavement. BACKGROUND Australia is a multicultural society and healthcare workers are faced with increasing numbers and diversity of immigrants to whom healthcare professionals strive to provide quality health care. METHODS A qualitative interpretive approach was used with data collected from a sample of 15 participants during focus group discussions. Data were collected in 2008-2009, transcribed and analysed. RESULTS The main themes and ideas identified in the dialogues were analysed under five main headings--Communication issues including disclosure and consent; Concepts of disease and illness; Attitudes towards medical treatments; Customs surrounding death, dying and bereavement; and Spiritual and religious issues. CONCLUSION The cultures and traditions of African countries vary widely; this study provides a snapshot of the views of a Sudanese African community about death and dying in Australia.
