Palliative sedation: more data and fewer opinions

Continuous Deep Sedation Until Death: First National Survey in France after the 2016 Law Promulgating It

CONTEXT

The French parliament passed a groundbreaking law in 2016, opening a right for patients to access continuous and deep sedation until death (CDS) at the end of life, under conditions. Parliamentarians' goal was to consolidate patients' rights whilst avoiding legislating on medical aid in dying.

OBJECTIVES

To conduct a first national retrospective survey on CDS to evaluate the number of CDS requested, proposed and performed in 2017 and to elicit qualitative data from physicians on the practice and on the terms used by patients to refer to CDS.

METHODS

Early 2018, an online survey was sent to all French hospitals, nursing homes, hospital at homes services and general practitioners (GPs). Descriptive statistics and qualitative inductive content analysis were used to analyze the data and comments of respondents.

RESULTS

The qualitative data show that respondents generally approve the law on CDS as it sets a legal framework; nonetheless, there is a persistent controversy about CDS vs. euthanasia for some physicians in all settings. GPs reported limited access to midazolam and the difficulty in organizing multidisciplinary procedures as major constraints. In hospital settings in particular, differentiating CDS from other sedation practices is uneasy. All physicians reported patients use multiple elements of language to request CDS.

CONCLUSION

After the law was passed in France, CDS were requested, proposed and performed in all medical settings, in nursing homes, at home. The qualitative data presented here show the relevance of exploring physicians' reflexive stances on this practice in different settings and within the context of a patient-physician relationship marked by a new patient's right. The study highlights the wide range of elements of language used by patients at the end of life, as understood by respondent physicians to mean a request for CDS and underscores the polymorphous meaning of CDS.

Clinical Aspects of Palliative Sedation in Prospective Studies. A Systematic Review

CONTEXT

Near the end of life when patients experience refractory symptoms, palliative sedation may be considered as a last treatment. Clinical guidelines have been developed, but they are mainly based on expert opinion or retrospective chart reviews. Therefore, evidence for the clinical aspects of palliative sedation is needed.

OBJECTIVES

To explore clinical aspects of palliative sedation in recent prospective studies.

METHODS

Systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and registered at PROSPERO. PubMed, CINAHL, Cochrane, MEDLINE, and EMBASE were searched (January 2014-December 2019), combining sedation, palliative care, and prospective. Article quality was assessed.

RESULTS

Ten prospective articles were included, involving predominantly patients with cancer. Most frequently reported refractory symptoms were delirium (41%-83%), pain (25%-65%), and dyspnea (16%-59%). In some articles, psychological and existential distress were mentioned (16%-59%). Only a few articles specified the tools used to assess symptoms. Level of sedation assessment tools were the Richmond Agitation Sedation Scale, Ramsay Sedation Scale, Glasgow Coma Scale, and Bispectral Index monitoring. The palliative sedation practice shows an underlying need for proportionality in relation to symptom intensity. Midazolam was the main sedative used. Other reported medications were phenobarbital, promethazine, and anesthetic medication-propofol. The only study that reported level of patient's discomfort as a palliative sedation outcome showed a decrease in patient discomfort.

CONCLUSION

Assessment of refractory symptoms should include physical evaluation with standardized tools applied and interviews for psychological and existential evaluation by expert clinicians working in teams. Future research needs to evaluate the effectiveness of palliative sedation for refractory symptom relief.

Palliative sedation: beliefs and decision-making among Spanish palliative care physicians

PURPOSE

To describe physician attitudes to deep palliative sedation.

METHODS

A nationwide e-survey of Spanish palliative care specialists was performed using vignettes which described patients close to death with intractable symptoms. Sedation levels were defined according to the Richmond Agitation-Sedation Scale. Multivariate analyses were performed to assess the explanatory factors involved in decision-making.

RESULTS

Responses of 292 palliative care specialists were analyzed (response rate 40%). Ninety-four percent, 87%, and 81% of the respondents supported the use of palliative sedation in cases of irreversible refractory symptoms as hyperactive delirium and dyspnea at rest secondary to lung cancer and GOLD stage IV COPD; 60% agreed with the use of palliative sedation in cases of existential suffering. Logistic regression analysis found as the explanatory factor in not performing palliative sedation the physicians' belief that sedation therapy constitutes undercover euthanasia (OR = 12, p < 0.01). Around 80% of physicians who decided on palliative sedation chose deep/complete sedation for every vignette; there were no common explanatory factors for decision-making for every vignette. The belief that sedation therapy equates to undercover euthanasia justifies not performing deep sedation in cases of irreversible refractory agitated delirium (OR = 7) and irreversible intractable dyspnea (OR = 6). Physician background in palliative care and sedation were associated with the selection of deep/complete sedation in cases of refractory delirium and cancer-associated dyspnea.

CONCLUSIONS

Spanish palliative physicians generally agree with the use of deep sedation as a proportionate treatment in dying patients with refractory symptoms. Decision-making is associated with physician beliefs regarding euthanasia and with the physician's background in palliative care and sedation.

The Path of Cicely Saunders: The “Peculiar Beauty” of Palliative Care

This paper is aimed at focusing on the writings and the experience of the Hospice movement Founder, Dame Cicely Saunders. The in-depth analysis carried out had the objective of verifying if “the way” of Cicely to understand, live and propose palliative care was still current and “beautiful”, so that we can nowadays refer to her fascinating “Original Palliative Care”. With “beauty” we mean, on the one hand, a way able to allow a personal path of research of the meaning of the disease and of the care, both for those who care and for those who are cared for. On the other hand, it seems to us that Cicely strongly suggests how this path can not be carried out alone, but is only possible within the context of a network of relationships and support, in a so called “relational autonomy”, for the patient, included in a “care ethics”. The authors believe that the work extensively documents as the overall approach of Cicely, traditional but always to be rediscovered, is still today the most convincing way of conception and action of palliative care.
