How palliative care professionals develop coping competence through their career: A grounded theory.

BACKGROUND: Palliative care professionals face emotional challenges when caring for patients with serious advanced diseases. Coping skills are essential for working in palliative care. Several types of coping strategies are mentioned in the literature as protective. However, little is known about how coping skills are developed throughout a professional career. AIM: To develop an explanatory model of coping for palliative care professionals throughout their professional career. DESIGN: A grounded theory study. Two researchers conducted constant comparative analysis of interviews. SETTING/PARTICIPANTS: Palliative care nurses and physicians across nine services from Spain and Portugal (n = 21). Theoretical sampling included professionals who had not continued working in palliative care. RESULTS: Professionals develop their coping mechanisms in an iterative five-stage process. Although these are successive stages, each one can be revisited later. First: commencing with a very positive outlook and emotion, characterized by contention. Second: recognizing one's own vulnerability and experiencing the need to disconnect. Third: proactively managing emotions with the support of workmates. Fourth: cultivating an integrative approach to care and understanding one's own limitations. Fifth: grounding care on inner balance and a transcendent perspective. This is a transformative process in which clinical cases, teamwork, and selfcare are key factors. Through this process, the sensations of feeling overwhelmed sometimes can be reversed because the professional has come to understand how to care for themselves. CONCLUSIONS: The explicative model presents a pathway for personal and professional growth, by accumulating strategies that modulate emotional responses and encourage an ongoing passion for work.

The state of transience, and its influence on the wish to die of advanced disease patients: insights from a qualitative phenomenological study.

BACKGROUND: The experience of Wish to Die is common in patients living with Advanced Disease. It has been studied worldwide and qualitative studies have contributed to the understanding of the complexity of the phenomenon of the WTD but a deeper understanding on the individual's views is still needed. The objective of this study was to identify common characteristics of the experience of wish to die in advanced disease. METHODS: A phenomenological study was carried out with multicenter participation of patients with advanced disease who had expressed their wish to die to health professionals. Semi-structured interviews were employed to obtain an in-depth perspective of each patient's lived experience. A phenomenological analysis of the data collected was performed to describe and explore the characteristic aspects of the phenomenon under study. RESULTS: Fourteen patients with advanced disease were interviewed. Most of them had cancer. In the analysis of the patients' accounts of their experiences, three common characteristics were identified: a) experiencing a state of transience; b) the attempt to reconnect with oneself; and c) additional disease-related aspects that influence the wish to die. Patients expressed the need for a safe space to address the wish to die and the importance of receiving care that considers both 'being' and 'doing'. CONCLUSIONS: Patients with advanced disease and wish to die experience a state of transience where the patient lives and ephemeral state of existence. Interventions focused on reinforcing the intrinsic value of the individual emerge as essential components of a compassionate accompaniment of those facing the wish to die.

Core Palliative Care Research Competencies Framework for Palliative Care Clinicians.

Background: Understanding the principles and practice of research by health care professionals helps to improve the evidence base for palliative care practice and service delivery. Research is a core competency in palliative care that enables the identification and addressing of problems for patients and their families, establishes best practice and improves ways to manage pain, other symptoms, and concerns. This work was undertaken in the research for all palliative care clinicians (RESPACC) Erasmus+ project. Aim: To identify and develop a set of core research competencies within a structured framework for all members of the multidisciplinary palliative team. Design: A multi-method approach was used including rapid review of literature, Nominal Group Technique, and expert consultation. A quiz to self-assess research competencies outlined within the Framework was produced. Results: The Framework includes 17 competencies organized in 7 domains: The clinical context, Scientific thinking and research design, Ethics and regulatory framework for research, Study and site management, Data management and informatics, Communication and relationships, and Research leadership. In the consultation process 6 of the 17 competencies were considered as required by each individual team member, and 3 to be present within the palliative care team. Conclusion: Using a multi-method approach, the first Palliative Care Research Framework identifying core research competencies for palliative care clinicians has been developed. The aim of the framework was not to transform palliative care clinicians into researchers, but to ensure that clinicians understand the important role of research and its integration into clinical practice.

A reflection on the essence of gratitude in palliative care: healing in severe disease and professional affirmation through accompanying patients until the end.

Background: Gratitude has sparked interest in the world of health. It is considered as a personality characteristic or as an emotion. However, little has been explored in the context of the interpersonal relationship of caring. An exploration in the context of end of life is ground-breaking. Objectives: This study analyses and reflects on the object of gratitude from the perspective of both the persons being cared for and the professionals providing health care. What are patients and their family members grateful for in palliative care? What is the reason for gratitude? What do these health professionals perceive when there is gratitude? These questions were answered considering the gratitude generated in health care encounters, not gratitude as personality trait. Methods: The phenomenological approach was used starting from lived clinical experiences. In the light of the dialogue between clinical experiences and philosophy, this study proposes an explanation of the 'real' or essential object of gratitude in palliative care. It was conducted within the context of palliative care. The study materials were manifestations of gratitude expressed or felt in clinical encounters and published in newspapers or shared in daily encounters. These were the basis for analysis and reflection and interdisciplinary dialogue. Findings: The analyses performed indicated healing or deep relief in serious diseases as objects of gratitude according to patients' perspective, and professional self-affirmation until the end according to the professionals' perspective. Conclusion: The two perspectives shared an important common fact, namely, the need to consider the persons in their entirety, and the importance of not losing sight of the value they have. This concept would characterize the nature of gratitude, its object being the 'objective good' for patients, family members, and palliative care professionals.

Monitoring the clinical practice of palliative sedation (PALSED) in patients with advanced cancer: an international, multicentre, non-experimental prospective observational study protocol.

BACKGROUND: Palliative sedation involves the intentional lowering of consciousness at the end of life. It can be initiated to relieve a patient's burden caused by refractory symptoms at the end of life. The impact of palliative sedation needs to be clinically monitored to adjust the proper dose and regimen of sedative medication to ensure that patients are at ease and comfortable at the end of their lives. Although there is consensus among health care professionals and within guidelines that efficacy of palliative sedation needs to be closely monitored, there is no agreement about how, when, and by whom, this monitoring should be performed. The aim of this study is to evaluate the effects of palliative sedation by measuring the discomfort levels and sedation/agitation levels of the patients at regular timepoints. In addition, the clinical trajectories of those patients receiving palliative sedation will be monitored and recorded. METHODS: The study is an international prospective non-experimental observational multicentre study. Patients are recruited from in-patient palliative care settings in Belgium, Germany, Italy, Spain and the Netherlands. Adult patients with advanced cancer are monitored by using proxy observations of discomfort (DS-DAT) and depth of sedation/agitation levels (RASS-PAL) during palliative sedation. After the palliative sedation period, the care for the specific participant case is evaluated by one of the attending health care professionals and one relative via a questionnaire. DISCUSSION: This study will be the first international prospective multicenter study evaluating the clinical practice of palliative sedation including observations of discomfort levels and levels of sedation. It will provide valuable information about the practice of palliative sedation in European countries in terminally ill cancer patients. Results from this study will facilitate the formulation of recommendations for clinical practice on how to improve monitoring and comfort in patients receiving palliative sedation. TRIAL REGISTRATION: This study is registered at Clinicaltrials.gov since January 22, 2021, registration number: NCT04719702.

WhatsApp as a facilitator of expressions of gratitude for palliative care professionals.

INTRODUCTION: Family members significantly value the professional and humane support that medical teams provide in the process of caring for patients with advanced diseases. Communication is currently changing, making it of interest to explore technology's possible influence on communication and on the care relationship. It remains unknown whether this can vary based on increased use of technology in patient care. Using communication technologies can facilitate recognition of professional support through the expression of gratitude aimed at healthcare professionals. The objective here is to describe expressions of gratitude sent via WhatsApp messages by patients who receive treatment from a palliative care team and their relatives. METHOD: A generic qualitative methodology was used. The palliative care service studied used WhatsApp in the patient/family-professional relationship. A content analysis of 130 WhatsApp messages sent to the professionals and containing expressions of gratitude was carried out. Two researchers inductively performed the analysis. Analysis included aspects for which senders were most grateful and others, such as who the messages came from, whether they were reactive or spontaneous and to whom they were directed. RESULTS: Almost all of the patients treated transmitted their gratitude via WhatsApp. It was also observed that family members were most grateful for features of the care received (i.e., affection, availability), the professional's support (i.e., accompaniment, comfort) and the professional's qualities (i.e., professionalism, kindness). They also appreciated symptom control and attempts to resignify loss; these aspects received the most expressions of gratitude in the messages. In turn, all the messages contain expressions of support for palliative care professionals, evidencing a patient/family-professional relationship. CONCLUSION: The use of communication technologies like WhatsApp can contribute to the perception of professionals' availability and closeness and become a facilitator of expressions of gratitude that specify the aspects that family members most appreciate from the palliative care team, such as skills related to humane care and availability.

Palliative Professionals' Experiences of Receiving Gratitude: A Transformative and Protective Resource.

Providing palliative care can be both challenging and rewarding. It involves emotionally demanding work and yet research shows that burnout is lower than in other fields of health care. Spontaneous expressions of gratitude from patients and family members are not uncommon and are highly valued. This study explored the experience of Spanish palliative professionals who received expressions of gratitude from their patients and families. A phenomenological approach was used to better understand the role of receiving gratitude in participants' lives. Interviews were transcribed verbatim and a phenomenological approach to analysis was undertaken using macro-thematic and micro-thematic reflection. Two team members independently engaged in this reflection with an inductive approach. The analysis was shared and discussed at periodic meetings to identify the key themes and sub-themes of the gratitude experience. Ten palliative professionals were interviewed. Participants engaged in a process of recognizing, internalizing, and treasuring the expressions of gratitude which they then used for reflection and growth. These expressions were a powerful and deeply meaningful resource that the palliative professionals revisited over time. Receiving expressions of gratitude invited a stronger sense of the value of one's self and one's work that was motivational and protective, particularly during challenging times.

The Decision-Making Process for Palliative Sedation for Patients with Advanced Cancer-Analysis from a Systematic Review of Prospective Studies.

BACKGROUND: The involvement of patients in decision making about their healthcare plans is being emphasized. In the context of palliative sedation, it is unclear how these decisions are made and who are involved in. The aim of the study is to understand how this decision-making is taken. METHOD: Information from a systematic review on clinical aspects of palliative sedation prospective studies were included. PubMed, CINAHL, Cochrane, MEDLINE, and EMBASE were searched (January 2014-December 2019). Data extraction and analysis regarded: (a) When and by whom the decision-making process is initiated; (b) patient involvement; (c) family involvement and (d) healthcare involvement. RESULTS: Data about decision making were reported in 8/10 included articles. Palliative sedation was reported in 1137 patients (only 16 of them were non-cancer). Palliative sedation was introduced by the palliative care team during the disease process, at admission, or when patients experienced refractory symptoms. Only two studies explicitly mentioned the involvement of patients in decision making. Co-decision between families and the regular health care professionals was usual, and the health care professionals involved had been working in palliative care services. CONCLUSION: Patient participation in decision making appeared to be compromised by limited physical or cognitive capacity and family participation is described. The possibility of palliative sedation should be discussed earlier in the disease process.

Gratitude from patients and relatives in palliative care-characteristics and impact: a national survey.

OBJECTIVES: To explore the expressions of gratitude (EoG) received from patients and relatives and their influence on palliative care professionals (PCPs). METHODS: A national online survey was sent to a representative of PCPs of each service listed in the national directory of palliative care (PC) services (n=272) (ie, hospital PC support team, hospice, paediatrics, etc). The questionnaire was pilot tested with experts. It comprised three sections: the overall perspective of receiving gratitude in the service, the personal experience of its influence and sociodemographic questions. A mailing schedule was designed to enhance the response rate. RESULTS: 186 representatives from all over Spain completed the questionnaire (68% response rate). 79% of service representatives reported that they almost always received EoG. These came mainly from families (93%). These EoG were very often put on display (84%) and shared with other health professionals (HPs) involved in care (45%). EoG evoked positive feelings in the team members. Based on their experience, respondents attributed different functions to these EoG: increased professional satisfaction (89%), a source of support in difficult times (89%), mood improvement, encouragement to continue and rewards for effort (88%). Services, where gratitude was more frequently received, were associated with PCPs who more frequently reported being proud of their work (p=0.039, Pearson's correlation test). CONCLUSIONS: Gratitude from patients and relatives was frequent and significant to those who work in PC. HPs considered that EoG offer multiple beneficial effects and also a protective role in their practice against distress and an increase in resilience skills.

Adaptation and continuous learning: integrative review of coping strategies of palliative care professionals.

BACKGROUND: Coping is essential to manage palliative care professionals' challenges. The focus has been on the effects of coping mechanism; however, little is known about coping itself in palliative care. AIM: To synthesise evidence of coping strategies in palliative care professionals, and how different strategies play roles over time. DESIGN: Systematically conducted integrative review. DATA SOURCES: PubMed; CINAHL; Medline; PsycINFO and B-ON were searched (1996-2021) combining 'coping' AND 'palliative care'. A predefined data extraction sheet was developed to report data. Two researchers performed constant comparative analysis using Nvivo®. RESULTS: Thirty-one studies were included. Four main strategies with recurrent reference to time were found: (a) proactive coping, involving activities to achieve self-confidence and control situations and emotions; (b) self-care based coping, including self-protection and self-awareness activities, with behavioural disconnection; (c) self-transformation coping, involving activities to accept limits; and (d) encountering deep professional meaning, is a coping mechanism based on meaning, frequently considering the deepest meaning of work. The dynamic and influencing factors were training, team interaction, professional motivation and family. They were usually protective factors, though sometimes they represented risk factors. The emotional burden associated with healthcare and systemic stressors were always risk factors. An explanatory model describes a complex and dynamic process, in which everyday strategies and more introspective strategies are combined. CONCLUSIONS: The model showed a process of adaptation and learning to persevere in palliative care. It changes over time under factors and strategies, and evolves in a personal and professional transformation, parallel to the working life. It would be worth assessing coping in healthcare professionals who chose to leave palliative care and to investigate the reasons they did so and their coping mechanisms.

Undertaking Research Using Online Nominal Group Technique: Lessons from an International Study (RESPACC).

Background: Nominal group technique (NGT) is a well-established research method for establishing consensus. Owing to the COVID-19 pandemic, research methods need to be adapted to engage with participants online. Objective: To determine the feasibility and acceptability of adapting NGT to an online format. Setting: Palliative care clinicians (n = 31) in Greece, Romania, and Spain. Methods: NGT discussions were used to elicit palliative care clinicians' opinions, and to rank priorities regarding their understanding and needs about clinical research. Preliminary online training of country-based facilitators was followed by content analysis of debriefing reports to capture learning related to the online NGT format. Results/Implementation: Three NGT sessions used online platforms (Zoom/MS Office/Mentimeter) for the meetings. Analysis of the facilitator reports generated three themes: preparation/facilitation/timing; optimizing technology; and interactions. Conclusions: Conducting NGT meetings online is viable and may be advantageous when compared with traditional face-to-face meetings, but requires careful preparation for participants to contribute effectively.

Wish to die and hasten death in palliative care: a cross-sectional study factor analysis.

OBJECTIVES: The wish to die (WTD) is a complex experience sometimes accompanied by intention to hasten death. The aim of this study is to identify the predictive factors for WTD and hastening death intention (HDI) in Spanish patients with advanced illness. METHODS: This is a subanalysis of a larger cross-sectional study conducted on patients experiencing advanced illness (N=201). Sociodemographic data and data related to symptom burden (Edmonton Symptom Assessment System-Revised), depressive and anxious symptoms (Hospital Anxiety and Depression Scale), demoralisation (Spanish version of the Demoralisation Scale), perceived loss of dignity (Patient Dignity Inventory) and WTD (Assessing Frequency and Extent of Desire to Die) were collected. The analysis used univariate and multivariate logistic regression. RESULTS: The prevalence of WTD in the sample was 18%, with 8 out of 36 patients reporting HDI. The independent factors predictive of WTD were (1) knowledge of approximate prognosis (OR=4.78; 95% CI 1.20 to 10.8; p=0.001); (2) symptom burden (OR=1.05; 95% CI 1.00 to 1.09; p=0.038); and (3) the Demoralisation Scale subsection 'lack of meaning and purpose in life' (OR=1.61; 95% CI 1.30 to 1.99; p=0.000). An independent predictive factor for HDI was the Demoralisation Scale subsection 'patients' distress and coping abilities' (OR=1.47; 95% CI 1.04 to 2.08; p=0.028), while having religious beliefs was a protective factor (OR=0.13; 95% CI0.17 to 0.97; p=0.047). CONCLUSIONS: Demoralisation was found to be the only common triggering factor for WTD and HDI, although experiences share certain features. Identification of the predictive factors for WTD and HDI may contribute to their prevention and management.

Insight and Inner Peace in Palliative Care Professionals after an Art Therapy Workshop Focused on Personal Self-Care: A Preliminary Experience.

Background: Emotional exhaustion is a problem many palliative care (PC) professionals face during their activity. Art therapy is emotionally beneficial for palliative patients who experience suffering, but its impact on professionals' experience of suffering has not been researched. Objective: To examine the immediate reactions of professionals after an art therapy workshop focused on personal self-care, also considering previously used coping strategies. Design: A four-hour art therapy workshop was designed including a generic qualitative study of participants. Participants were PC professionals and their reactions were examined using an ad hoc questionnaire with open-ended questions. Descriptive analysis of quantitative variables and thematic analysis of open-ended questions were conducted. Results: Seventeen professionals participated voluntarily. They rated the workshop positively, using words such as "calm" and "relaxation" to express the effects of the workshop, which they considered therapeutic and a source of self-awareness. For some, it allowed them to release emotions; for others, it enabled introspection and opened up a more elaborated emotional response. They thought artistic expression would be useful for their colleagues, or even for their own personal development. In the workshop, professionals opened up and explained how they face intense moments on a day-to-day basis: how they approach the situation, or how they try to control their surroundings; how they disconnect/distance themselves; and how they consider circumstances as a learning process and source of self-nurturing. Participants described art therapy as calming, healing the most intense feelings, and feeding the soul. Conclusion: Professionals reacted immediately with enthusiasm to art therapy, positively assessing its effects. Some attributed effects are in line with daily strategies of connecting with one's inner self. Others are about promoting self-awareness and inner peace, while providing healing opportunities. Art therapy may play a role in self-care for the PC professional, and should be researched further. Research Ethics Committee of the Universidad de Navarra approved the study (Number: 2019.167).

Palliative Care Professionals' Message to Others: An Ethnographic Approach.

INTRODUCTION: Palliative care continues to be misunderstood within the world of healthcare. Palliative care professionals are key agents for promoting a greater understanding of their field. This study aims to examine the messages, both implicit and explicit, that palliative care professionals transmit about themselves and their work within their teams and to other health professionals. METHODS: Focused ethnographic secondary analysis, exploring the interactions of palliative care professionals as it happens at everyday work. An inductive thematic analysis was developed from 242 h of observation of the daily work practices of palliative care professionals, focusing on their interactions with others. The data was coded without predefined categories, and the analysis was performed independently by two researchers. RESULTS: Palliative professionals communicate that they are part of an active team working in an organized manner. They value and feel proud of their work. Despite the intensity of their work, these professionals are always available to others, to whom they demonstrate a clear professional identity. They convey their expertise in alleviating suffering, respectful behavior and collaborative ability. CONCLUSION: Professionals, in their daily work, communicate through their messages the essence of palliative care. It is essential that palliative care professionals perceive themselves as potential influencers and explicitly transmit the reasons for their intervention. Otherwise, others will perpetuate the myths, misunderstandings, and lack of a positive reputation for palliative care.

Innovative teaching strategies in palliative care: Reading of a phenomenological text on the experience of living with advanced cancer.

BACKGROUND: Pedagogical strategies in palliative care are diverse and mainly aimed to understand patients with advanced disease and improving their care. Phenomenological texts are stories intended to evoke lived experiences and help understand complex situations. AIM: To determine what thoughts, experiences and feelings nursing students have when reading a phenomenological text about the experience of a person living with advanced cancer. DESIGN AND METHOD: A descriptive qualitative study with palliative care students of the nursing degree at two university centres. The students reflected on a phenomenological text. A thematic analysis of the 14 reflections was performed. The reflections were analysed inductively and independently, and periodic sessions were held to discuss the identified categories and topics. RESULTS: The students' writings showed that reading the phenomenological text caused them to reflect and feel moved and challenged. The impact on the students is grouped into three categories: the experience of the corporeality of patients with advanced disease makes students aware of the importance of the body; the disease as an individual transformative process challenges students; and the experiences of people with advanced cancer make students aware of the importance of how they care for patients and their families. CONCLUSION: The reading of a phenomenological text on the experience of living with advanced cancer may be a teaching method that can generate experiences that promote reflective and experiential learning in nursing students. It seems to be a useful tool for teaching in subjects focusing on person-centred care.

Cross-sectional survey of the wish to die among palliative patients in Spain: one phenomenon, different experiences.

OBJECTIVE: Cultural backgrounds and values have a decisive impact on the phenomenon of the wish to die (WTD), and examination of this in Mediterranean countries is in its early stages. The objectives of this study were to establish the prevalence of WTD and to characterise this phenomenon in our cultural context. METHODS: A cross-sectional study with consecutive advanced inpatients was conducted. Data about WTD (Assessing Frequency & Extent of Desire to Die (AFFED) interview) and anxiety and depression (Edmonton Symptom Assessment System-revised (ESAS-r)) were collected through two face-to-face clinical encounters. Data were analysed with descriptive statistics, χ2 and analysis of variance. RESULTS: 201 patients participated and 165 (82%) completed both interviews. Prevalence of WTD was 18% (36/201) in the first interview and 16% (26/165) in the second interview (p=0.25). After the first interview, no changes in depression (p=0.60) or anxiety (p=0.90) were detected. The AFFED shows different experiences within WTD: 11% of patients reported a sporadic experience, while 7% described a persistent experience. Thinking about hastening death (HD) appeared in 8 (22%) out of 36 patients with WTD: 5 (14%) out of 36 patients considered this hypothetically but would never take action, while 3 (8%) out of 36 patients had a more structured idea about HD. In this study, no relation was detected between HD and frequency of the appearance of WTD (p=0.12). CONCLUSIONS: One in five patients had WTD. Our findings suggest the existence of different experiences within the same phenomenon, defined according to frequency of appearance and intention to hasten death. A linguistically grounded model is proposed, differentiating the experiences of the 'wish' or 'desire' to die, with or without HD ideation.

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.

How to measure the effects and potential adverse events of palliative sedation? An integrative review.

BACKGROUND: Palliative sedation is the monitored use of medications intended to relieve refractory suffering. The assessment of palliative sedation has been focused on the assess of the level of consciousness but a more comprehensive approach to assessment is needed. AIM: To understand how the potential effects and possible adverse events of palliative sedation in Palliative Care patients are measured. DESIGN: Integrative review of most recent empirical research. DATA SOURCES: Cochrane Library, Embase, Medline, PubMed, and CINAHL were searched (2010-2020) using the terms sedation, palliative care, terminal care, assessment. Limits included studies in English and adults. Inclusion criteria were: scientific assessment papers, effects and complications of palliative sedation; patients with incurable illness. RESULTS: Out of 588 titles, 26 fulfilled inclusion criteria. The Discomfort Scale-Dementia of Alzheimer Type and Patient Comfort Score were used to assess comfort. The Richmond Agitation-Sedation Scale and The Ramsay Sedation Scale are the most used to measure its effect. Refractory symptoms were assessed through multi-symptom or specific scales; except for psychological or existential distress. Delirium was assessed using the Memorial Delirium Assessment Scale and pain through the Critical Care Pain Observation Tool. The use of technical approaches to monitor effects is upcoming. There is lack of measurement of possible adverse events and variability in timing measurement. CONCLUSIONS: There are palliative care validated instruments to assess the sedation effect but this review shows the need for a more standardized approach when assessing it. Instruments should be used within an experienced and trained expert, providing a holistic assessment.
