Palliative Sedation in Patients With Advanced Cancer Followed at Home: A Prospective Study

ContextHome care programs in Italy.ObjectivesThe aim of this study was to assess a protocol for palliative sedation (PS) performed at home.MethodsA total of 219 patients were prospectively assessed to evaluate a PS protocol in patients with advanced cancer followed at home by two home care programs with different territorial facilities. The protocol was based on stepwise administration of midazolam.ResultsA total of 176 of the patients died at home, and PS was performed in 24 of these patients (13.6%). Younger patients received the procedure more frequently than older patients (P = 0.012). The principal reasons to start PS were agitated delirium (n = 20) and dyspnea (n = 4). Mean duration of PS was 42.2 ± 30.4 hours, and the mean doses of midazolam were 23–58 mg/day. Both the home care team and the patients' relatives expressed optimal or good levels of satisfaction with the procedure in all but one case, respectively.ConclusionThis protocol for PS was feasible and effective in minimizing distress for a subgroup of patients who died at home. The characteristics of patients who may be effectively sedated at home should be better explored in future studies.

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

ContextNear 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.ObjectivesTo explore clinical aspects of palliative sedation in recent prospective studies.MethodsSystematic 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.ResultsTen 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.ConclusionAssessment 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.     

Belgian General Practitioners' Perspectives on the Use of Palliative Sedation in End-of-Life Home Care: A Qualitative Study

ContextPalliative sedation (PS) is a far-reaching palliative measure with a life-shortening potential. Guidelines provide only for a restricted use of PS and as a last resort.ObjectivesTo explore PS practice in end-of-life (EoL) home care.MethodsThis was a qualitative analysis of semi-structured interviews with 52 general practitioners (GPs) of Flanders, Belgium.ResultsApart from GPs who adhere to the existing prerequisites for PS, opinions diverge among GPs on the indication area for PS and on possible life-shortening intentions. The key to GPs' broadened view on “which suffering merits PS” is the fragile context of EoL home care, and the key to GPs' possible life-shortening intentions is their need to facilitate the dying process, when trying or lengthy. When honoring a terminally ill patient's request for euthanasia, several GPs prefer slow euthanasia using PS to a lethal injection.ConclusionPS home practice deviates from the PS guidelines' recommendations. In addition to the GPs' shortage of knowledge, the guidelines' recommendations do not always meet the particular needs of EoL home care. If one consideration of EoL home care is to respect a patient's wish to die at home, then the pre-emptive use of PS to avoid a futile transfer to the hospital in the case of an undesirable turn of events deserves more attention in the PS debate.     

Late Referrals to Palliative Care Units in Japan: Nationwide Follow-Up Survey and Effects of Palliative Care Team Involvement After the Cancer Control Act

Referral to palliative care units tends to be delayed. In Japan, the Cancer Control Act was established in 2006 to improve the quality of life of cancer patients by facilitating greater access to specialized palliative care services. The primary aims of this study were to clarify the family-perceived appropriateness of the timing of referral to palliative care units after the Cancer Control Act, and to determine the effects of the involvement of the palliative care team on the family-perceived referral timing. An additional aim of this study was to clarify the family-perceived usefulness of the palliative care team. A multicenter questionnaire survey was conducted on a sample of 661 bereaved family members of cancer patents who were admitted to palliative care units in Japan. A total of 451 responses were analyzed (response rate: 68%). Half of the bereaved family members regarded the timing of referrals to palliative care units as late or too late: too late (25%, n = 114), late (22%, n = 97), appropriate (47%, n = 212), early (2.4%, n = 11), and very early (1.8%, n = 8). Among 228 families who reported that patients had commented on the timing of referrals, about half reported that the patients said the timing of referral was late or too late: too late (23%, n = 52), late (21%, n = 49), appropriate (48%, n = 110), early (4.4%, n = 10), and very early (3.1%, n = 7). The families of patients with a palliative care team (n = 191) tended to report less frequently that they believed the referral timing to be late or too late (43% vs. 51%, P = 0.073); they also reported significantly less frequently that the patients said that the referral timing was late or too late (36% vs. 52%, P = 0.037). The percentages of families who evaluated the palliative care team as useful or very useful were: 93% (symptom control), 90% (emotional support), 92% (family support), and 87% (care coordination). Half of the Japanese bereaved families of patients admitted to palliative care units regarded the timing of referrals as late or too late, and the rates identified in the survey were similar to those recorded before the Cancer Control Act. Involvement of the palliative care team, however, significantly correlated with lower family- and patient-perceived late referrals, and palliative care team activity was generally perceived as useful by the bereaved family members. Further dissemination of palliative care teams could contribute to better access to palliative care units and quality palliative care throughout the country.

Modeling the Longitudinal Transitions of Performance Status in Cancer Outpatients: Time to Discuss Palliative Care

ContextUnderstanding the longitudinal transitions of performance status among persons with cancer can assist providers in determining the appropriate time to initiate palliative care support.ObjectivesTo model longitudinal transitions of performance status in cancer outpatients, to determine the probabilities of improvement and deterioration in performance status over time, and to evaluate the factors associated with rates of transitions.MethodsThis population-based, retrospective, cohort study comprised adult outpatients diagnosed with any type of cancer and assessed for performance status throughout their observation period using the Palliative Performance Scale (PPS; scale 0–100; 0 indicates death). At every PPS assessment, patients were assigned to one of four states: stable state (PPS score 70–100), transitional state (PPS score 40–60), end-of-life state (PPS score 10–30), or dead. A Markov multistate model under the presence of interval censoring was used to examine the rate of state-to-state transitions.ResultsThere were 11,374 patients representing nearly 71,000 assessments. Patients with lung cancer in the transitional state had a 27.7% chance of being dead at the end of one month vs. 17.5% in patients with breast cancer. The average time spent in the transitional state was 6.6 weeks for patients diagnosed with gastrointestinal cancer vs. 8.8 weeks for patients with breast cancer. The rate at which one moves from the transitional state to death was higher for patients with lung cancer than those with breast cancer.ConclusionWe estimated the probability and direction of change in performance status in cancer outpatients. Entry into the transitional state may serve as an indicator for referral for palliative care support. Mean end-of-life sojourn times are too short to allow meaningful integration of palliative care.     

Risk Factors for Developing Prolonged Grief During Bereavement in Family Carers of Cancer Patients in Palliative Care: A Longitudinal Study

ContextFamily carers of palliative care patients report high levels of psychological distress throughout the caregiving phase and during bereavement. Palliative care providers are required to provide psychosocial support to family carers; however, determining which carers are more likely to develop prolonged grief (PG) is currently unclear.ObjectivesTo ascertain whether family carers reporting high levels of PG symptoms and those who develop PG disorder (PGD) by six and 13 months postdeath can be predicted from predeath information.MethodsA longitudinal study of 301 carers of patients receiving palliative care was conducted across three palliative care services. Data were collected on entry to palliative care (T1) on a variety of sociodemographic variables, carer-related factors, and psychological distress measures. The measures of psychological distress were then readministered at six (T2; n = 167) and 13 months postdeath (T3; n = 143).ResultsThe PG symptoms at T1 were a strong predictor of both PG symptoms and PGD at T2 and T3. Greater bereavement dependency, a spousal relationship to the patient, greater impact of caring on schedule, poor family functioning, and low levels of optimism also were risk factors for PG symptoms.ConclusionScreening family carers on entry to palliative care seems to be the most effective way of identifying who has a higher risk of developing PG. We recommend screening carers six months after the death of their relative to identify most carers with PG.     

Latent Class Analysis of Specialized Palliative Care Needs in Adult Intensive Care Units From a Single Academic Medical Center

Context

In the intensive care unit (ICU), 14% of patients meet criteria for specialized palliative care, but whether subgroups of patients differ in their palliative care needs is unknown.

Prevalence of Delirium in End-of-Life Palliative Care Patients: An Observational Study

ObjectivesThe aim of this study was to assess the prevalence of delirium, using the Assessment Test for Delirium and Cognitive Impairment (4AT) in end-of-life palliative care patients.Subjects and MethodsThis retrospective cross-sectional study was conducted on end-of-life patients in a hospice or at home. All patients were evaluated with the 4AT for the presence of delirium.ResultsOf the 461 patients analyzed, 76 (16.5%) were inpatients and 83.5% (385) outpatients. The median age was 79.5 (72–86) years, and 51.0% were female. According to the 4AT score, 126 patients (27.3%) had delirium (A4T ≥4) at admission, 28 (36.8%) were inpatients, and 98 (25.5%) outpatients. Around 33.8% of the cancer inpatients had delirium, while 20.6% of the cancer outpatients had delirium. The prevalence of delirium varied according to the setting, clinical condition, and life expectancy. In addition, 55.0% (11) actively dying inpatients, within 3 days, had delirium, and 56.7% (17) outpatients had delirium; while among those with life expectancy longer than 4 days, 30.4% (17) inpatients and 22.8% (81) outpatients were with delirium.ConclusionsOur study confirms that delirium is common in cancer and noncancer palliative care patients. Further research on delirium in end-of-life palliative care patients should consider the complexity of palliative care of this population as well as of the characteristics of the settings.
