Palliative sedation in a specialized unit for acute palliative care in a cancer hospital: comparing patients dying with and without palliative sedation

Palliative sedation is undergoing extensive debate. The aims of this study were to describe the practice of palliative sedation at a specialized acute palliative care unit and to study whether patients who received palliative sedation differed from patients who did not. We performed a systematic retrospective analysis of the medical and nursing records of all 157 cancer patients who died at the acute palliative care unit between 2001 and 2005. Palliative sedation, defined as continuous deep sedation prior to death, was used for 43% of all deceased patients. In 87% of the sedated patients, it was started in the last two days before death. Sedated and nonsedated patients did not differ in survival after admission (eight days vs. seven days, P = 0.12). Sedated patients were younger (55 years vs. 59 years, P = 0.04) and more often had malignancies of the digestive tract (P < 0.01). In both groups, common symptoms at admission were pain (79% vs. 87%, P = 0.23), constipation, (40% vs. 48%, P = 0.46), and dyspnea (32% vs. 29%, P = 0.77). On the day that palliative sedation was started, sedated patients more often suffered from dyspnea and delirium than nonsedated patients at a comparable day before death. The most important indications for palliative sedation were terminal restlessness (60%) and dyspnea (46%). We conclude that at the studied acute palliative care unit, patients who ultimately received palliative sedation did not have symptoms different than nonsedated patients at admission, but on the day at which the sedation was started, they suffered more often from delirium and dyspnea.     

Changes in medical and nursing care in cancer patients transferred from a palliative care team to a palliative care unit

The primary aim of this study was to explore the changes in medical/nursing care in patients who transferred from a palliative care team (PCT) to a palliative care unit (PCU) in the same hospital, and to explore the reasons why new or modified interventions were required. This was a retrospective study of 50 consecutive patients who were transferred from PCT to PCU in a 750-bed general hospital. A trained nurse performed a chart review and recorded the changes in 1) medical/nursing care, 2) help with decision-making within 48 hours after PCU admission, and 3) documentation of family and psycho-existential care. Group discussions among PCT and PCU staff members explored the potential reasons for the changes. Five patients were excluded due to admission periods of shorter than 48 hours. The number of new/modified medical and nursing care interventions after PCU admission averaged 1.9 ± 1.5 and 1.5 ± 1.3 per patient, respectively. The most common medical treatments were: reduction in hydration volume, dose titration of opioids, change in opioid administration device, opioid rotation, and addition of NSAIDs and steroids. The most common nursing interventions were: allowing patient to take a bath, changing mattress, use of massage, and discontinuation of bronchial suctioning. In addition, PCU staff newly coordinated opportunities to discuss preferred end-of-life care with primary caregivers in 38% of the cases, family members other than primary caregivers in 16%, and patients in 6.7%. The chart documentation of family care and psycho-existential care increased considerably after PCU admission. The chief reasons for these changes were: under-recognition of the problems and unavailability of treatments (pharmacological treatments), no intention to intervene and recommendations not followed by primary physicians (rehydration therapy), no intention to intervene (nursing care), and no intention to intervene and under-recognition of the problems (help with decision-making). These data demonstrate that many patients under PCT consultation receive new or modified interventions after PCU admission. Potentially useful strategies to strengthen the PCT interventions are: modification of intervention structure to minimize under-recognition of symptoms and decision making problems (e.g., use of standardized assessment tools, regular conferences), changes in the health care system to allow unlicensed drugs, clinical studies to clarify the benefits of artificial hydration therapy, and greater efforts to intervene in the areas of nursing care, help with decision making, family care, and psycho-existential care.     

Efficacy and safety of remimazolam-based sedation for intensive care unit patients undergoing upper gastrointestinal endoscopy: a cohort study

BACKGROUND:Remimazolam is a novel ultra-short-acting sedative, but its safety and adverse events (AEs) in high-risk patients in the intensive care unit (ICU) setting remain unknown.METHODS:This was a single-center, retrospective study that compared remimazolam to propofol and midazolam in patients undergoing upper gastrointestinal endoscopy. The primary outcome was the incidence of treatment-related AEs. The secondary outcomes were the time to extubation, the length of ICU stay, and the average ...     

Family experience with palliative sedation therapy for terminally ill cancer patients

Symptomatic sedation is often required in terminally ill cancer patients, and could cause significant distress to their family. The aims of this study were to clarify the family experience during palliative sedation therapy, including their satisfaction and distress levels, and the determinants of family dissatisfaction and high-level distress. A multicenter questionnaire survey assessed 280 bereaved families of cancer patients who received sedation in 7 palliative care units in Japan. A total of 185 responses were analyzed (response rate, 73%). The families reported that 69% of the patients were considerably or very distressed before sedation. Fifty-five percent of the patients expressed an explicit wish for sedation, and 89% of families were clearly informed. Overall, 78% of the families were satisfied with the treatment, whereas 25% expressed a high level of emotional distress. The independent determinants of low levels of family satisfaction were: poor symptom palliation after sedation, insufficient information-giving, concerns that sedation might shorten the patient's life, and feelings that there might be other ways to achieve symptom relief. The independent determinants of high levels of family distress were: poor symptom palliation after sedation, feeling the burden of responsibility for the decision, feeling unprepared for changes in the patient's condition, feeling that the physicians and nurses were not sufficiently compassionate, and shorter interval to patient death. Palliative sedation therapy was principally performed to relieve severe suffering based on family and patient consent. Although the majority of families were comfortable with this practice, clinicians should minimize family distress by regular monitoring of patient distress and timely modification of sedation protocols, providing sufficient information, sharing the responsibility of the decision, facilitating grief, and providing emotional support.     

Differences in physician-reported practice in palliative sedation therapy

Background Although palliative sedation therapy is often required in terminally ill cancer patients, little is known about actual practice. The aims of this study were to clarify the physician-reported sedation practices and the factors influencing the sedation rates.Methods A questionnaire was sent to 105 representative physicians of all certified palliative care units in Japan. A total of 81 responses were analyzed (effective response rate, 80%).Results The prevalence of continuous-deep sedation for physical symptoms was <10% in 33 institutions (41%), 10–50% in 43 institutions (53%), and >50% in 5 institutions (6.2%). The prevalence of continuous-deep sedation for psychoexistential suffering was 0% in 52 institutions (64%), 0.5–5% in 26 institutions (32%) and more than 10% in 3 institutions (3.6%). Continuous-deep sedation was more frequently performed by physicians who did not believe clear consciousness was necessary for a good death, who did not believe that sedation often shortened patient life, who worked with nurses specializing in cancer/palliative care, who judged the symptoms as refractory without actual trials of treatments, who performed continuous sedation first rather than intermittent sedation, and who used phenobarbitones frequently.Conclusions Physician-reported practice in palliative sedation therapy varied widely among institutions. The differences were mainly associated with the physicians philosophy about a good death, physicians belief about the effects of sedation on patient survival, and physicians medical practice. Discussion should be focused on these divergent areas, and clear clinical guidelines are urgently needed to provide valid end-of-life care.     

A national guideline for palliative sedation in the Netherlands

The first national guideline on palliative sedation in The Netherlands has been adopted by the General Board of the Royal Dutch Medical Association. By law, the physician is obliged to take this guideline into consideration. In this paper, we present the main principles of the guideline. Palliative sedation is defined as the intentional lowering of consciousness of a patient in the last phase of his or her life. The aim of palliative sedation is to relieve suffering, and lowering consciousness is a means to achieve this. The indication for palliative sedation is the presence of one or more refractory symptoms that lead to unbearable suffering for the patient. Palliative sedation is given to improve patient comfort. It is the degree of symptom control, not the level to which consciousness is lowered, which determines the dose and the combinations of the sedatives used and duration of treatment. Palliative sedation is normal medical practice and must be clearly distinguished from the termination of life.     

Implementation and evaluation of a network-based pilot program to improve palliative care in the intensive care unit

Background

Intensive care unit (ICU) care could be improved by implementation of time-triggered evidence-based interventions including identification of a patient/family medical decision maker, the patient’s advance directive status, and cardiopulmonary resuscitation preferences by Day 1; offer of social work and spiritual support by Day 3; and a family meeting establishing goals of care by Day 5. We implemented a program to improve care for ICU patients in five Department of Veterans Affairs’ ICUs.

Measures

We measured the percent of ICU patients with lengths of stay of five or more days that received the care processes by the appropriate day.

Intervention

Critical care and palliative care providers trained ICU nurse teams to improve care through auditing, performance feedback, improvement tools, education, and monthly team meetings.

Outcomes

Pre- and postintervention care were compared. Offering social work and spiritual support, identification of the medical decision maker, and documentation of family meetings significantly improved.

Conclusions/Lessons Learned

ICU nurse teams can be engaged to improve care under the aegis of a collaborative quality improvement project.     

Bringing palliative care to a Canadian cancer center: the palliative care program at Princess Margaret Hospital

It is increasingly recognized that complete care of the patient with cancer includes palliative care, which is applicable early in the course of illness, in conjunction with life-prolonging treatment. Princess Margaret Hospital (PMH) is Canada’s largest center for cancer care and research, and it is an international referral center for patients with cancer. The Palliative Care Program at PMH has developed into a comprehensive clinical, educational, and research program, with an acute palliative care unit, daily palliative care clinics, a cancer pain clinic, and a consultation service that sees urgent consultations on a same-day basis in inpatient and outpatient areas. We will describe the components, successes, and challenges of our program, which may be useful for others, who are developing palliative care programs in an academic setting.     

Ethical issues in palliative care

Ethical problems in medicine are common, especially when caring for patients at the end of life. However, many of these issues are not adequately identified in the outpatient setting. Primary care providers are in a unique and privileged position to identify ethical issues, prevent future conflicts, and help patients make medical decisions that are consistent with their individual values and preferences. This article describes some of the more common ethical issues faced by primary care physicians caring for patients with life-limiting illness.     

A critical review of daily sedation interruption in the intensive care unit

Background. Daily sedation interruption (DSI) has been proposed as a method of improving sedation management of critically ill patients by reducing the adverse effects of continuous sedation infusions. Aim. To critique the research regarding daily sedation interruption, to inform education, research and practice in this area of intensive care practice. Design. Literature review. Method. Medline, CINAHL and Web of Science were searched for relevant key terms. Eight research‐based studies, published in the English language between 1995–December 2006 and three conference abstracts were retrieved. Results. Of the eight articles and three conference abstracts reviewed, five originated from one intensive care unit (ICU) in the USA. The research indicates that DSI reduces ventilation time, length of stay in ICU, complications of critical illness, incidence of post‐traumatic stress disorder and is reportedly used by 15–62% of ICU clinicians in Australia, Europe, USA and Canada. Conclusions. DSI improves patients’ physiological and psychological outcomes when compared with routine sedation management. However, research relating to these findings has methodological limitations, such as the use of homogenous samples, single‐centre trials and retrospective design, thus limiting their generalisability. Relevance to clinical practice. DSI may provide clinicians with a simple, cost‐effective method of reducing some adverse effects of sedation on ICU patients. However, the evidence supporting DSI is limited and cannot be generalised to heterogeneous ICU populations internationally. More robust research is required to assess the potential impact of DSI on the physical and mental health of ICU survivors.     

Association between symptom distress and survival in outpatients seen in a palliative care cancer center

Clinical observation and preliminary reports suggest that higher scores for symptoms such as pain may be associated with shorter survival. We undertook a survival analysis to determine whether symptom expression in outpatients with complex cancer is related to the duration of their survival. Participants were 225 outpatients with cancer evaluated in our comprehensive cancer center for pain management or palliative care over a 10-week period ending June 2000. In addition to age and other clinical and demographic information, the patients completed the Anderson Symptom Assessment System (ASAS), which assesses pain, fatigue, nausea, depression, anxiety, drowsiness, shortness of breath (dyspnea), appetite, sleep, and feeling of well-being on a 0–10 scale. Univariate analyses showed that higher symptoms of dyspnea, drowsiness, problems with appetite, and nausea were significantly associated with shorter survival whereas pain, depression and other ASAS items were not. In multivariate analyses, only higher levels of dyspnea and drowsiness showed a significant association (P = 0.01 and P = 0.02, respectively) with shorter survival. Knowledge about these symptoms may be important in formulating adaptive randomization techniques for clinical trials and for research concerning estimates of survival.     

The impact of the palliative care mobile team on symptom assessment and medication profiles in patients admitted to a comprehensive cancer center

Goals of work In recent years, tertiary care hospitals and cancer centers have shown great interest in forming palliative care consultation teams. Thus, these centers may be interested in the types of care that such teams give, which could help the other centers put together their own teams. However, the availability of such information is limited. The purpose of our study was therefore to describe the experience of a palliative care team at our comprehensive cancer center. Materials and methods We reviewed the medical records of 100 consecutive patients who were referred to our palliative care mobile team between November 2004 and January 2005; we then analyzed the primary interventions of this team. Results The median patient age was 61 years; 57 patients were female. The most frequent symptoms were fatigue in 78% and pain in 62% of patients. The main interventions by the palliative team were changes in medication types (opioids, antiemetics, neuroleptics, and laxatives) and in medication doses. Conclusions Palliative care mobile teams make multiple changes in previous medications and provide almost universal counseling services to patients and families. The length of involvement with the patient and family is short; therefore, rapid stabilization and counseling are required. Our findings regarding medication changes could be helpful to tertiary care hospitals and cancer centers considering palliative care consultation teams.     

Quality of end-of-life treatment for cancer patients in general wards and the palliative care unit at a regional cancer center in Japan: a retrospective chart review

Goals In Japan, most cancer patients die in the hospital. The aim of this study was to assess the quality of end-of-life treatment for dying cancer patients in general wards and palliative care unit (PCU). Materials and methods A retrospective chart review study was conducted. The following data on cancer patients who died in general wards (N = 104) and PCU (N = 201) at a regional cancer center were collected: do-not-resuscitate (DNR) decisions, treatments in the last 48 h of life, and aggressiveness of cancer care for dying patients. Main results DNR orders were documented for most patients (94% in general wards, 98% in PCU, p = 0.067) and families usually consented (97%, 97%, p = 0.307). Comparison of general wards with PCU showed that, in the last 48 h of life, significantly more patients in general wards received life-sustaining treatment (resuscitation, 3.8%, 0%, p = 0.001; mechanical ventilation, 4.8%, 0%, p = 0.004), large volume hydration (>1,000 ml/day, 67%, 10%, p < 0.001) with continuous administration (83%, 5%, p = 0.002) and fewer palliative care drugs (strong opioids, 68%, 92%, p < 0.001; corticosteroids, 49%, 70%, p < 0.001; nonsteroidal anti-inflammatory drugs, 34%, 85%, p < 0.001). Regarding aggressiveness of cancer care, patients received a new chemotherapy regimen within 30 days of death (3.0%), chemotherapy within 14 days of death (4.3%), and intensive care unit admission in the last month of life (3.3%). Conclusion We found that families, not patients, consented to DNR, and life-sustaining treatments were appropriately withheld; however, patients on general wards received excessive hydration, and the use of palliative care drugs could be improved. Application of our findings can be used to improve clinical care in general wards.     

Palliative sedation: a review of the research literature

The overall aim of this paper is to systematically review the following important aspects of palliative sedation: prevalence, indications, survival, medication, food and fluid intake, decision making, attitudes of physicians, family experiences, and efficacy and safety. A thorough search of different databases was conducted for pertinent research articles published from 1966 to June 2007. The following keywords were used: end of life, sedation, terminal sedation, palliative sedation, refractory symptoms, and palliative care. Language of the articles was limited to English, French, German, and Dutch. Papers reporting solely on the sedatives used in palliative care, without explicitly reporting the prevalence or intensity of sedation, and papers not reporting on primary research (such as reviews or theoretical articles) were excluded. Methodological quality was assessed according to the criteria of Hawker et al. (2002). The search yielded 130 articles, 33.8% of which were peer-reviewed empirical research studies. Thirty-three research papers and one thesis were included in this systematic review. This review reveals that there still are many inconsistencies with regard to the prevalence, the effect of sedation, food and fluid intake, the possible life-shortening effect, and the decision-making process. Further research to clarify all of this should be based on multicenter, prospective, longitudinal, and international studies that use a uniform definition of palliative sedation, and valid and reliable instruments. Only through such research will it be possible to resolve some of the important ethical issues related to palliative sedation.     

吸入镇静在重症医学科的应用

重症医学科（ICU）镇静治疗已成为一项基本的治疗措施。最近文献报道ICU应用吸入镇静在唤醒时间、简单遵医嘱动作时间上要短于持续静脉注射镇静,而且有心脏、大脑等器官功能保护作用。目前国内ICU尚未见吸入镇静报道,本文将对吸入镇静在ICU中的应用做一综述。     

Application of quality audit tools to evaluate care quality received by terminal cancer patients admitted to a palliative care unit

GOALS: We aimed to evaluate the palliative care quality for terminal cancer patients as a reference for prospective service improvements. PATIENTS AND METHODS: A prospective study was conducted to analyze the quality audit data collected from 1,476 samples in one medical center's palliative care unit. Lai's modified version of the support team assessment schedule was utilized for 2-year data collection, applying 17 categories of audit criteria rated on a scale of 0 to 4 (0-no symptoms, 4-significant symptoms). The quality audit criteria were scored weekly for 2 weeks following patient admission. RESULTS: Average scores of quality audit criteria from admission to week 2 were 10.05, 8.85, and 8.49, respectively, with statistical differences noted weekly. Efficacy of palliative care was most evident 2 weeks after hospitalization. Factors with statistically significant differences between admission and week 1 included: pain control, constipation, vomiting, anorexia, other symptom control, patient anxiety, self awareness and preparation of patient for illness, self awareness and preparation of family for illness, and satisfaction of patient's spiritual belief and life philosophy. Factors with statistically significant differences between weeks 1 and 2 included: pain control, other symptom control, self awareness and preparation of family for illness, and satisfaction of patient's spiritual belief and life philosophy. CONCLUSIONS: Patients in hospice care received adequate symptom relief. Total quality audit scores declined progressively over the 2 weeks following patient admission, indicating efficacy of palliative care quality.     

Adoption of a sedation scoring system and sedation guideline in an intensive care unit

AIM: The paper presents a study assessing the rate of adoption of a sedation scoring system and sedation guideline. BACKGROUND: Clinical practice guidelines including sedation guidelines have been shown to improve patient outcomes by standardizing care. In particular sedation guidelines have been shown to be beneficial for intensive care patients by reducing the duration of ventilation. Despite the acceptance that clinical practice guidelines are beneficial, adoption rates are rarely measured. Adoption data may reveal other factors which contribute to improved outcomes. Therefore, the usefulness of the guideline may be more appropriately assessed by collecting adoption data. METHOD: A quasi-experimental pre-intervention and postintervention quality improvement design was used. Adoption was operationalized as documentation of sedation score every 4 hours and use of the sedation and analgesic medications suggested in the guideline. Adoption data were collected from patients' charts on a random day of the month; all patients in the intensive care unit on that day were assigned an adoption category. Sedation scoring system adoption data were collected before implementation of a sedation guideline, which was implemented using an intensive information-giving strategy, and guideline adoption data were fed back to bedside nurses. After implementation of the guideline, adoption data were collected for both the sedation scoring system and the guideline. The data were collected in the years 2002-2004. FINDINGS: The sedation scoring system was not used extensively in the pre-intervention phase of the study; however, this improved in the postintervention phase. The findings suggest that the sedation guideline was gradually adopted following implementation in the postintervention phase of the study. Field notes taken during the implementation of the sedation scoring system and the guideline reveal widespread acceptance of both. CONCLUSION: Measurement of adoption is a complex process. Appropriate operationalization contributes to greater accuracy. Further investigation is warranted to establish the intensity and extent of implementation required to positively affect patient outcomes.     

Supportive and palliative care of cancer patients at the Kantonsspital St. Gallen,Switzerland

In 1991, the first unit for oncology palliative care within an oncology centre in the country was opened in St. Gallen, Switzerland. The main admission criterion is symptom distress due to advanced cancer disease. The mean duration of hospitalisation was 23 days in 140 patients in 1994. Approximately one third of the patients die within the unit, while one third can be discharged for home care. The aims and strategies of interdisciplinary palliative care are described. The need for the 11-bed unit is documented by its high occupancy, by patient satisfaction and by its influence on palliative care development in and outside the country.     

Predictors of inpatient mortality in an acute palliative care unit at a comprehensive cancer center

Goals of work  

Predicting inpatient mortality has clinical and financial implications and helps improve the care of patients with advanced cancer and their families. Models with excellent validity and reliability are available for mortality prediction in intensive care units. The purpose of the current study was to determine factors associated with increased likelihood of mortality in an acute palliative care unit (APCU).
