- Abstract
This paper describes a project undertaken by the Hospice Palliative End-of-Life Care Surveillance Team Network--one of four Cancer Surveillance and Epidemiology Networks established by the Canadian Partnership Against Cancer in 2009 to create information products that can be used to inform cancer control. The project was designed to improve the quality and use of existing electronic patient databases in its member organizations. The project's intent was to better understand terminally ill cancer patients in their final year of life, with noncancer as comparison. The network created an early design for a Web-based end-of-life care surveillance system prototype. Using a flagging process, anonymized data sets on cancer/ noncancer palliative patients and those who died in 2008-2009 were extracted and analyzed. The Australian palliative approach was adapted as the conceptual model based on the data sets available. Common data elements were defined then mapped to local data sets to create a common data set. Information products were created as online reports. Throughout the project, members were engaged in knowledge translation. Overall, the project was well received by network members. There are still major data-quality and linkage issues that require further work.

- Abstract
Purpose: the Thai PPS Adult Suandok tool was translated from the Palliative Performance Scale (PPSv2) and had been used in Chiang Mai, Thailand for several years., Aim: to test the reliability and validity of the Thai translation of PPSv2., Design: a set of 22 palliative cases were used to determine a PPS score on Time-1, and repeated two weeks later as Time-2. A survey questionnaire was also completed for qualitative analysis., Participants: a total of 70 nurses and physicians from Maharaj Nakorn Hospital in Chiang Mai participated., Results: The Time-1 intraclass correlation coefficient (ICC) for absolute agreement is 0.911 (95% CI 0.86-0.96) and for consistency is 0.92 (95% CI 0.87-0.96). The Time-2 ICC for agreement is 0.905 (95% CI 0.85-0.95) and for consistency is 0.912 (95% CI 0.86-0.96). These findings indicate good agreement among participants and also were somewhat higher in the Time-2 re-test phase. Cohen's kappa score is 0.55, demonstrating a moderate agreement. Thematic analysis from the surveys showed that 91% felt PPS to be a valuable clinical tool overall, with it being 'very useful' or 'useful' in several areas, including care planning (78% and 20%), disease monitoring (69% and 27%) and prognostication (61% and 31%), respectively. Some respondents noted difficulty in determining appropriate scores in paraplegic patients or those with feeding tubes, while others found the instructions long or difficult., Conclusion: the Thai PPS Adult Suandok translated tool has good inter- and intra-rater reliability and can be used regularly for clinical care.

- Abstract
Background: There is a paucity of randomized studies evaluating the value of palliative interventions on a prospective basis in newly diagnosed oncology patients. We sought to prospectively evaluate quality of life (QoL) outcomes in advanced cancer patients who received discussion-based palliative care interventions from an advanced registered nurse practitioner (ARNP) integrated into the oncology team, and compare these outcomes with a control population., Methods: Patients with metastatic cancer were randomized to standard care or an ARNP-directed intervention that included discussions of the benefits of hospice, discussions on living wills and advanced directives (Five Wishes document) along with an assessment of QoL. Relevant endpoints included change from baseline QoL and improvement in hospice knowledge., Results: From November 13, 2008, through July 28, 2009, 26 patients were accrued at the Mayo Clinic in Jacksonville, Florida. The study closed early due to published data demonstrating the benefits of early palliative care interventions in the management of metastatic cancer patients. Statistically significant improvements from baseline were noted in emotional and mental QoL assessments in the intervention group that were not seen in the control group. Patients found it useful to have the living will and Five Wishes documents offered as part of the ARNP intervention., Conclusions: An ARNP-directed intervention that explains the benefits of hospice and addresses advanced directives early in the course of metastatic cancer patients' treatment, is well received by the patients and their relatives and leads to measurable improvement in the patient's emotional and mental QoL.

- Abstract
Objective: The Bereavement Risk Assessment Tool (BRAT) was designed to consistently communicate information affecting bereavement outcomes; to predict the risk for difficult or complicated bereavement based on information obtained before the death; to consider resiliency as well as risk; and to assist in the efficacy and consistency of bereavement service allocation. Following initial development of the BRAT's 40 items and its clinical use, this study set out to test the BRAT for inter-rater reliability along with some basic validity measures., Method: Case studies were designed based on actual patients and families from a hospice palliative care program. Bereavement professionals were recruited via the internet. Thirty-six participants assessed BRAT items in 10 cases and then estimated one of 5 levels of risk for each case. These were compared with an expert group's assignment of risk., Results: Inter-rater reliability for the 5-level risk scores yielded a Fleiss' kappa of 0.37 and an intra-class correlation (ICC) of 0.68 (95% CI 0.5-0.9). By collapsing scores into low and high risk groups, a kappa of 0.63 and an ICC of 0.66 (95% CI 0.5-0.9) was obtained. Participant-estimated risk scores yielded a kappa of 0.24. Although opinion varied on the tool's length, participants indicated it was well organized and easy to use with potential in assessment and allocation of bereavement services. Limitations of the study include a small sample size and the use of case studies. Limitations of the tool include the subjectivity of some items and ambiguousness of unchecked items., Significance of Results: The collapsed BRAT risk levels show moderately good inter-rater reliability over clinical judgement alone. This study provides introductory evidence of a tool that can be used both prior to and following a death and, in conjunction with professional judgment, can assess the likelihood of bereavement complications.

- Abstract
Background: This retrospective study analyzed sudden functional decline using the Palliative Performance Scale (PPSv2) for patients recently admitted to a palliative care unit (PCU) to determine if this adversely affects survival. There were 3328 patients in the cohort over a 13-year period admitted to a tertiary palliative care bed (71.1%) or a residential hospice bed (28.9%). Patient age ranged from 17-102 years old with 51.9% female and 48.1% male; the majority (88.3%) had a cancer diagnosis., Results: Given several limitations noted in the study, six preliminary findings emerged: (1) The lower the initial PPS at PCU admission, the higher the likelihood of an abrupt drop occurring shortly after admission; (2) An abrupt decline in function appears to be associated with smaller survival probabilities; (3) A greater increment change in PPS may be associated with shorter survival probabilities; (4) The lower the PPS on admission, the shorter the survival; (5) When dropping a specific increment amount, the new survival projection appears similar to the PPS level dropped to; and (6) Sudden or abrupt functional decline may be a sentinel event., Conclusions: The data provide evidence that abrupt functional decline implies the likelihood of shorter survival in palliative care patients and may act as a sentinel marker. It is unclear whether these findings would be generalizable outside of a PCU. These results should be interpreted with caution as a prospective evaluation is needed to confirm the results. If substantiated, it may be that incorporating sudden functional decline into palliative prognostic models may increase their predictive accuracy.

- Abstract
Although there is a growing body of knowledge on survival prediction in populations with advanced cancer receiving palliative care using the Palliative Performance Scale (PPS), this literature has focused on disease, gender, and care location, and less is known about how to apply such knowledge to be clinically meaningful. To address this issue, we evaluated a database comprising 13 years of initial PPS scores on 6066 patients, which were recorded on their first assessment by the Victoria Hospice palliative care team in the home or palliative care unit setting. Our results reaffirmed PPS as a significant predictor of survival, with increasing survival times associated with higher PPS levels. We explored survival time distributions, a life expectancy table, and a survival nomogram as three potential ways to assist in estimating survival times in palliative care. We also evaluated the concept of Kaplan-Meier survival curve "nose-tail" refinement, and observed that this approach requires more research. More work is needed to better identify those who live "longer than expected" or die "sooner than expected" to provide clinical utility in discussion with patients and families.

- Abstract
This study examines the use of the Palliative Performance Scale (PPS) in end-of-life prognostication within a regional palliative care program in a Canadian province. The analysis was done on a prospective cohort of 513 patients assessed by a palliative care consult team as part of an initial community/hospital-based consult. The variables used were initial PPS score, age, gender, diagnosis, cancer type, and survival time. The findings revealed initial PPS to be a significant predictor of survival, along with age, diagnosis, cancer type and site, but not gender. The survival curves were distinct for PPS 10%, 20%, and 30% individually, and for 40%-60% and > or =70% as bands. This is consistent with earlier findings of the ambiguity and difficulty when assessing patients at higher PPS levels because of the subjective nature of the tool. We advocate the use of median survival and survival rates based on a local cohort where feasible, when reporting individual survival estimates.

- Abstract
This paper aims to reconcile the use of Palliative Performance Scale (PPSv2) for survival prediction in palliative care through an international collaborative study by five research groups. The study involves an individual patient data meta-analysis on 1,808 patients from four original datasets to reanalyze their survival patterns by age, gender, cancer status, and initial PPS score. Our findings reveal a strong association between PPS and survival across the four datasets. The Kaplan-Meier survival curves show each PPS level as distinct, with a strong ordering effect in which higher PPS levels are associated with increased length of survival. Using a stratified Cox proportional hazard model to adjust for study differences, we found females lived significantly longer than males, with a further decrease in hazard for females not diagnosed with cancer. Further work is needed to refine the reporting of survival times/probabilities and to improve prediction accuracy with the inclusion of other variables in the models.

- Abstract
With changes in bowel function being a common and often distressful issue for palliative care patients, the ability to easily monitor and record changes in bowel status would be helpful in addressing quality of care. Most bowel tools record either constipation or diarrhea, but not both. A new tool, the Victoria Bowel Performance Scale (BPS), was designed as an ordinal nine-point scale from -4 (severe constipation) to +4 (severe diarrhea) and includes three parameters: visual stool characteristics, bowel pattern, and ability to control defecation. This study tested the reliability of BPS using case scenarios in a test-retest format. Sixty-seven raters in Time Period 1 and 54 raters in Time Period 2 ranked the 18 cases. The intraclass correlation coefficients for absolute agreement were 0.822 and 0.853 for Time Periods 1 and 2, respectively. Results showed that the raters were consistent in their scoring over time, with an average Cohen's kappa of 0.70 over all of the raters. The average Pearson correlation coefficient between Time Periods 1 and 2 scores was 0.92. Further prospective testing in day-to-day clinical care is needed to further confirm the reliability and clinical utility of the BPS. A BPS management guideline has been developed to assist with decision making for each BPS score, which also requires validation.

- Abstract
Background: Current literature suggests clinicians are not accurate in prognostication when estimating survival times of palliative care patients. There are reported studies in which the Palliative Performance Scale (PPS) is used as a prognostic tool to predict survival of these patients. Yet, their findings are different in terms of the presence of distinct PPS survival profiles and significant covariates., Objective: This study investigates the use of PPS as a prognostication tool for estimating survival times of patients with life-limiting illness in a palliative care unit. These findings are compared to those from earlier studies in terms of PPS survival profiles and covariates., Methods: This is a retrospective cohort study in which the admission PPS scores of 733 palliative care patients admitted between March 3, 2000 and August 9, 2002 were examined for survival patterns. Other predictors for survival included were age, gender, and diagnosis., Results: Study findings revealed that admission PPS score was a strong predictor of survival in patients already identified as palliative, along with gender and age, but diagnosis was not significantly related to survival. We also found that scores of PPS 10% through PPS 50% led to distinct survival curves, and male patients had consistently lower survival rates than females regardless of PPS score., Conclusion: Our findings differ somewhat from earlier studies that suggested the presence of three distinct PPS survival profiles or bands, with diagnosis and noncancer as significant covariates. Such differences are likely attributed to the size and characteristics of the patient populations involved and further analysis with larger patient samples may help clarify PPS use in prognosis.
