Concepts and definitions for “supportive care,” “best supportive care,” “palliative care,” and “hospice care” in the published literature, dictionaries, and textbooks

PurposeCommonly used terms such as “supportive care,” “best supportive care,” “palliative care,” and “hospice care” were rarely and inconsistently defined in the palliative oncology literature. We conducted a systematic review of the literature to further identify concepts and definitions for these terms.MethodsWe searched MEDLINE, PsycInfo, EMBASE, and CINAHL for published peer-reviewed articles from 1948 to 2011 that conceptualized, defined, or examined these terms. Two researchers independently reviewed each citation for inclusion and then extracted the concepts/definitions when available. Dictionaries/textbooks were also searched.ResultsNine of 32 “SC/BSC,” 25 of 182 “PC,” and 12 of 42 “HC” articles focused on providing a conceptual framework/definition. Common concepts for all three terms were symptom control and quality-of-life for patients with life-limiting illness. “SC” focused more on patients on active treatment compared to other categories (9/9 vs. 8/37) and less often involved interdisciplinary care (4/9 vs. 31/37). In contrast, “HC” focused more on volunteers (6/12 vs. 6/34), bereavement care (9/12 vs. 7/34), and community care (9/12 vs. 6/34). Both “PC” and “SC/BSC” were applicable earlier in the disease trajectory (16/34 vs. 0/9). We found 13, 24, and 17 different definitions for “SC/BSC,” “PC,” and “HC,” respectively. “SC/BSC” was the most variably defined, ranging from symptom management during cancer therapy to survivorship care. Dictionaries/textbooks showed similar findings.ConclusionWe identified defining concepts for “SC/BSC,” “PC,” and “HC” and developed a preliminary conceptual framework unifying these terms along the continuum of care to help build consensus toward standardized definitions.

Survival prediction for advanced cancer patients in the real world: A comparison of the Palliative Prognostic Score, Delirium-Palliative Prognostic Score, Palliative Prognostic Index and modified Prognosis in Palliative Care Study predictor model

PURPOSE The aim of this study was to investigate the feasibility and accuracy of the Palliative Prognostic Score (PaP score), Delirium-Palliative Prognostic Score (D-PaP score), Palliative Prognostic Index (PPI) and modified Prognosis in Palliative Care Study predictor model (PiPS model). PATIENTS AND METHODS This multicentre prospective cohort study involved 58 palliative care services, including 19 hospital palliative care teams, 16 palliative care units and 23 home palliative care services, in Japan from September 2012 to April 2014. Analyses were performed involving four patient groups: those treated by palliative care teams, those in palliative care units, those at home and those receiving chemotherapy. RESULTS We recruited 2426 participants, and 2361 patients were finally analysed. Risk groups based on these instruments successfully identified patients with different survival profiles in all groups. The feasibility of PPI and modified PiPS-A was more than 90% in all groups, followed by PaP and D-PaP scores; modified PiPS-B had the lowest feasibility. The accuracy of prognostic scores was ⩾69% in all groups and the difference was within 13%, while c-statistics were significantly lower with the PPI than PaP and D-PaP scores. CONCLUSION The PaP score, D-PaP score, PPI and modified PiPS model provided distinct survival groups for patients in the three palliative care settings and those receiving chemotherapy. The PPI seems to be suitable for routine clinical use for situations where rough estimates of prognosis are sufficient and/or patients do not want invasive procedure. If clinicians can address more items, the modified PiPS-A would be a non-invasive alternative. In cases where blood samples are available or those requiring more accurate prediction, the PaP and D-PaP scores and modified PiPS-B would be more appropriate.

Effect of continuous deep sedation on survival in patients with advanced cancer (J-Proval): a propensity score-weighted analysis of a prospective cohort study

BACKGROUND Continuous deep sedation (CDS) before death is a form of palliative sedation therapy that has become a focus of strong debate, especially with respect to whether it shortens survival. We aimed to examine whether CDS shortens patient survival using the propensity score-weighting method, and to explore the effect of artificial hydration during CDS on survival. METHODS This study was a secondary analysis of a large multicentre prospective cohort study that recruited and followed up patients between Sept 3, 2012, and April 30, 2014, from 58 palliative care institutions across Japan, including hospital palliative care settings, inpatient palliative care units, and home-based palliative care services. Adult patients (aged ≥ 20 years) with advanced cancer who received care through the participating palliative care services were eligible for this secondary analysis. Patients with missing data for outcome variables or who lived for more than 180 days were excluded. We compared survival after enrolment between patients who did and did not receive CDS. We used a propensity score-weighting method to control for patient characteristics, disease status, and symptom burden at enrolment. FINDINGS Of 2426 enrolled patients with advanced cancer, we excluded 289 (12%) for living longer than 180 days and 310 (13%) with missing data, leaving an analysis population of 1827 patients. 269 (15%) of 1827 patients received CDS. Unweighted median survival was 27 days (95% CI 22-30) in the CDS group and 26 days (24-27) in the no CDS group (median difference -1 day [95% CI -5 to 4]; HR 0·92 [95% CI 0·81-1·05]; log-rank p=0·20). After propensity-score weighting, these values were 22 days (95% CI 21-24) and 26 days (24-27), respectively (median difference -1 day [95% CI -6 to 4]; HR 1·01 [95% CI 0·87-1·17]; log-rank p=0·91). Age (p(interaction)=0·67), sex (p(interaction)=0·26), performance status (p(interaction)=0·90), and volume of artificial hydration (p(interaction)=0·14) did not have an effect modification on the association between sedation and survival, although care setting did have a significant effect modification (p(interaction)=0·021). INTERPRETATION CDS does not seem to be associated with a measurable shortening of life in patients with advanced cancer cared for by specialised palliative care services, and could be considered a viable option for palliative care in this setting.

Referral criteria for outpatient specialty palliative cancer care: an international consensus.

Although outpatient specialty palliative-care clinics improve outcomes, there is no consensus on who should be referred or the optimal timing for referral. In response to this issue, we did a Delphi study to develop consensus on a list of criteria for referral of patients with advanced cancer at secondary or tertiary care hospitals to outpatient palliative care. 60 international experts (26 from North America, 19 from Asia and Australia, and 11 from Europe) on palliative cancer care rated 39 needs-based criteria and 22 time-based criteria in three iterative rounds. Nearly all experts responded in each round. Consensus was defined by an a-priori agreement of 70% or more. Panellists reached consensus on 11 major criteria for referral: severe physical symptoms, severe emotional symptoms, request for hastened death, spiritual or existential crisis, assistance with decision making or care planning, patient request for referral, delirium, spinal cord compression, brain or leptomeningeal metastases, within 3 months of advanced cancer diagnosis for patients with median survival of 1 year or less, and progressive disease despite second-line therapy. Consensus was also reached on 36 minor criteria for specialist palliative-care referral. These criteria, if validated, could provide guidance for identification of patients suitable for outpatient specialty palliative care.

Surprise Questions for Survival Prediction in Patients With Advanced Cancer: A Multicenter Prospective Cohort Study

BACKGROUND Predicting the short-term survival in cancer patients is an important issue for patients, family, and oncologists. Although the prognostic accuracy of the surprise question has value in 1-year mortality for cancer patients, the prognostic value for short-term survival has not been formally assessed. The primary aim of the present study was to assess the prognostic value of the surprise question for 7-day and 30-day survival in patients with advanced cancer. PATIENTS AND METHODS The present multicenter prospective cohort study was conducted in Japan from September 2012 through April 2014, involving 16 palliative care units, 19 hospital-based palliative care teams, and 23 home-based palliative care services. RESULTS We recruited 2,425 patients and included 2,361 for analysis: 912 from hospital-based palliative care teams, 895 from hospital palliative care units, and 554 from home-based palliative care services. The sensitivity, specificity, positive predictive value, and negative predictive value of the 7-day survival surprise question were 84.7% (95% confidence interval [CI], 80.7%-88.0%), 68.0% (95% CI, 67.3%-68.5%), 30.3% (95% CI, 28.9%-31.5%), and 96.4% (95% CI, 95.5%-97.2%), respectively. The sensitivity, specificity, positive predictive value, and negative predictive value for the 30-day surprise question were 95.6% (95% CI, 94.4%-96.6%), 37.0% (95% CI, 35.9%-37.9%), 57.6% (95% CI, 56.8%-58.2%), and 90.4% (95% CI, 87.7%-92.6%), respectively. CONCLUSION Surprise questions are useful for screening patients for short survival. However, the high false-positive rates do not allow clinicians to provide definitive prognosis prediction. IMPLICATIONS FOR PRACTICE The findings of this study indicate that clinicians can screen patients for 7- or 30-day survival using surprise questions with 90% or more sensitivity. Clinicians cannot provide accurate prognosis estimation, and all patients will not always die within the defined periods. The screened patients can be regarded as the subjects to be prepared for approaching death, and proactive discussion would be useful for such patients.

Referral Criteria for Outpatient Palliative Cancer Care: A Systematic Review

Outpatient clinics are increasingly being recognized for their critical role in facilitating early palliative care access. This systematic review highlighted the lack of consensus in the literature on which patients should be referred in the ambulatory setting. Cancer diagnosis, prognosis, physical symptoms, performance status, psychosocial distress, and end-of-life care planning needs may be taken into consideration when appropriate candidates are being identified.

Complications of a Gastrostomy Tube Used for Decompression of an Inoperable Bowel Obstruction in a Patient with Advanced Cancer

Percutaneous gastrostomy tubes (G-tubes) are used to decompress symptomatic patients with inoperable malignant bowel obstruction. Complications of G-tubes have rarely been reported in the palliative care literature. Nonetheless, complications are not uncommon and could interfere with the quality of life of patients, as illustrated by our case report. Given the increased use of percutaneous G-tubes, more attention needs to be paid to the prevention, early detection, and treatment of potential adverse events. Patients and their caregivers must receive appropriate education about complications of G-tubes and be made aware of the early signs and symptoms that must be brought to the attention of health care providers. Management of complications requires the use of health care resources that often can be found only in an acute care setting, and often requires referral to an interventional radiologist or endoscopist. Routine referral for G-tube placement before medical management has been maximized may not minimize suffering in patients with life-limiting illnesses.

Uniform definition of continuous-deep sedation

www.thelancet.com/oncology Vol 17 June 2016 e222 Richmond Agitation-Sedation Scale. The use of an intervention protocol will enable us to compare the results on the actual consciousness levels, efficacy, and safety of CDS. The benefits and risks should—and can—be compared in clinical trials. If empirical study findings suggest that some types of protocol-based so-called CDS do not actually reduce patient consciousness levels, this intervention can be called a part of standard symptom management in the future. Not intent alone, not results alone, but a standardised protocol with reasonable intent and reproducible outcomes is the key to future investigations.

Hypocalcemia Associated with Strontium-89 Administration in a Patient with Diffuse Bone Metastases from Neuroendocrine Carcinoma

Metastatic bone disease is often associated with severe pain in cancer patients, and has become an increasingly important quality-of-life issue. Radionuclides, such as strontium-89 (Sr-89), have provided effective palliation of metastatic bone pain. Although strontium follows the biochemical pathways of calcium in the body, changes in calcium homeostasis related to Sr-89 therapy have rarely been reported. We present a case of a 32-year-old male with poorly differentiated neuroendocrine carcinoma and extensive skeleton metastases who developed profound hypocalcemia after Sr-89 administration.

Prevalence and predictors of conflict in the families of patients with advanced cancer: A nationwide survey of bereaved family members

Family conflict has several adverse impacts on caregivers. Thus, there is significant value in determining the prevalence and predictors of family conflict, which can enable the health care provider to intervene if family conflict arises during end‐of‐life care. Accordingly, we aimed to explore the prevalence and predictors of conflict among the families of patients with advanced cancer who died in palliative care units.
