End-of-Life Health Resource Utilization for Limited English-Proficient Patients With Advanced Non-Small-Cell Lung Cancer.

Limited English-proficient (LEP) patients with non-small-cell lung cancer (NSCLC) may receive less palliative care services and more likely to receive aggressive end-of-life (EoL) care. Goals of this retrospective cohort study are to compare access to community palliative home care (CPHC), do not resuscitate (DNR) form completion, place of death, and health resource utilization at EoL between English-proficient (EP) and LEP patients with NSCLC in Vancouver, Canada. All patients with advanced NSCLC referred in 2016 and received medical care were included. Patients were classified as LEP if seen with a medical interpreter. Descriptive statistics and univariate and multivariate analyses were used to compare the outcomes between the two groups. One hundred eighty-six patients were referred, 66% EP. Rates of CPHC referral and DNR form completion were the same for both groups (84% and 92%, P = 1.00). LEP patients received earlier access to CPHC (15 v 10 weeks before death, P = .039). Rates of ER visits within 6 months and 30 days of death were 0.89 for EP patients and 0.7 for LEP patients, P = .374, and 0.1 for EP patients and 0.13 for LEP patients, P = .244. Hospitalization rates within 6 months and 30 days of death were 1.4 for EP patients and 1.59 for LEP patients, P = .640, and 0.67 for EP patients and 0.81 for LEP patients, P = .091. EP patients were more likely to have a home death (26% v 14%), whereas LEP patients died in acute care (23% v 14%) or a tertiary palliative care unit (24% v 19%). This was not statistically significant (P = .335). LEP patients had better median overall survival (8.5 v 5.4 months, P < .001), but when controlled by age, mutation, and EP status, only receipt of palliative-intent systemic therapy was statistically significant. EP and LEP patients with NSCLC have similar referral rates to CPHC, DNR form completion, and EoL health resource utilization. The measured EoL variables did not demonstrate significant disparities between EP and LEP patients.

The effects of ketamine on pain control in stage IV cancer patients receiving palliative care

Background: We evaluated the effects of intravenous ketamine on cancer pain in stage IV cancer patients receiving palliative care.Methods: In total, 253 stage IV cancer patients with cancer pain hospitalized at a single tertiary hospital palliative care unit were included. The ketamine group contained 112 patients receiving ketamine, and the control group comprised 141 non-ketamine users. To evaluate the odds ratios (ORs) for favorable pain control, optimal pain control, and opioid-sparing effect among ketamine users, we used multivariable logistic regression adjusted for age and objective prognosis score. Differences in the visual analog scale (VAS) score, oral morphine equivalents, inter-dose frequency, and inter-dose amount were compared between both groups at the time of ketamine introduction (T0), after 24 hours (T1), and after 48 hours (T2) using repeated-measures analysis of covariance.Results: The ketamine group was more likely to show favorable pain control (OR, 3.84; 95% confidence interval [CI], 1.76–8.37) and an optimal response (OR, 3.99; 95% CI, 1.73–9.22) than the control group. Compared to the control group, the ketamine group showed a higher VAS score at T0, but a more evident VAS score reduction at T1 and T2 (pint&lt;0.001). The ketamine group was less likely than the control group to experience depressive mood (OR, 0.31; 95% CI, 0.10–0.92), but had a higher risk of delirium (OR, 2.06; 95% CI, 1.12–3.91).Conclusion: Our findings suggest that ketamine can effectively reduce refractory cancer pain in stage IV cancer patients.

C-reactive protein and white blood cell count are adverse prognostic markers for patients with advanced cancer on parenteral nutrition in a palliative care unit setting: A retrospective cohort study

Background: Parenteral nutrition is controversial in patients with advanced cancer. Nevertheless, this treatment is common practice near the end of life. Aim: We aimed to identify factors which were associated with the outcome of patients on parenteral nutrition at an academic tertiary palliative care unit. Design: In this retrospective cohort study patients were assigned to two groups according to parenteral nutrition treatment. Inferential statistics were used to assess whether the dynamics of laboratory variables over 2 weeks of parenteral nutrition were associated with survival. Setting/Participants: Patients admitted to the Department of Palliative Medicine at the Medical University of Vienna between 2016 and 2018 were included in this study. Results: Of 443 patients, 113 patients received parenteral nutrition. Patients had a lower body mass index, lower levels of bilirubin, γ-glutamyltransferase, alkaline phosphatase, and were of younger age compared to patients which did not receive parenteral nutrition. No difference in survival as measured from admission to death was found when comparing the two groups. Levels for γ-glutamyltransferase, alkaline phosphatase, and C-reactive protein significantly increased during 2 weeks of parenteral nutrition. Among patients with parenteral nutrition, an increase in C-reactive protein or white blood cell count levels was associated with lower survival. Conclusion: Patients who responded with an increase of C-reactive protein or white blood cell count during 2 weeks after reinitiation or start of parenteral nutrition had a worse survival. Our findings might support clinicians and patients in their decision to forgo parenteral nutrition in a palliative care setting.

Increased number of deaths within 24 h of admission during a period of social restriction related to the COVID-19 pandemic: A retrospective service evaluation in a metropolitan palliative care unit

Background: COVID-19 has led to implementation of wide-ranging social restriction measures with consequent impact on health care utilisation in many domains. There is little published data on the experience of palliative care services catering to a population with low case numbers of COVID-19. Aim: This study aimed to consider the impact of COVID-19 on utilisation of inpatient palliative care in the context of low community transmission, and low numbers of cases in hospital. Design: A retrospective service evaluation examining differences in number of admissions, diagnoses, number of deaths and time from admission to death, across three discrete 8-week time periods spanning the early COVID-19 pandemic. Setting/participants: All admissions (n = 194) to a metropolitan tertiary hospital inpatient palliative care unit in Melbourne during the study period. Results: An initial 16.9% fall in admissions was followed by a return to baseline admission numbers, with a 46.7% increase in number of deaths compared to baseline. The number of deaths within 24 h rose from 10.8% to 37.3% (p < 0.01). The number of patients with non-malignant diagnoses increased from 32.4% to 52%, and those with non-malignant diagnoses were more likely to die rapidly (p < 0.01). There were no patients with COVID-19 infection. Conclusion: Increased numbers of deaths within 24 h of admission occurred on the palliative care unit despite low COVID-19 case numbers in the wider community, and in the setting of widespread social restriction measures. More research is needed examining the health-related consequences of such restrictions for individuals not infected with COVID-19.

First-line methadone for cancer pain: titration time analysis.

Methadone is a low-cost, strong opioid that is increasingly used as a first-line treatment for pain in palliative care (PC). Its long and unpredictable half-life and slow elimination phase can make titration challenging. Evidence for titration modalities is scarce. To describe the titration phase of the treatment with low-dose first-line methadone and the use of methadone for breakthrough pain. Prospective study with strong opioid-naïve patients with moderate to severe cancer pain followed at a tertiary PC unit in Argentina. Starting methadone dose was 2.5-5 mg/day every 8, 12, or 24 h. Titration allowed daily dose increases from day 1, and prescription of oral methadone 2.5 mg every 2 h with a maximum of 3 rescue doses/day for breakthrough pain. Pain control, methadone stabilization dose, and adverse effects, among other variables, were daily assessed over the first 7 days (T0-T7). Sixty-two patients were included. Initial median (IQR) methadone dose was 5(2.5) mg/day. Pain intensity decreased from a median (IQR) of 8 (2.3) at T0 to 4 (2.3) at T1 and remained ≤ 4 until T7 (all p < 0.0001 compared to T0). Similar results were obtained through the categorical and tolerability scales for pain. Fifty patients (81%) reached pain control, 66% in the first 48 h. Methadone daily doses at T2 and T7 were higher than that at T0: 7.5 (3) and 6.7 (5.5) versus 5 (2.5), respectively (all p < 0.05). The opioid escalation index at T7 was 1.7%. The median (IQR) number of rescues, stabilization dose, and time for stabilization was 0 (1), 5(4.5) mg, and 3(2) days, respectively. Two patients were discontinued due to delirium. All other side effects were mild. First-line, low-dose methadone using rescue methadone resulted in a pronounced and rapid decrease in pain, with minimal need for titration and for breakthrough doses, and no evidence of accumulation or sedation by the end of the week.

Prevalence and Factors Associated With Will-to-Live in Patients With Advanced Disease: Results From a Portuguese Retrospective Study

ContextWill-to-live (WtL) is a complex and multifactorial dimension of end-of-life experience. Health care decisions on assisted suicide and euthanasia are rarely based on WtL evidence-based discussions. ObjectivesTo inform the debate, we aimed to evaluate the prevalence of WtL and its associations within a tertiary home-based palliative care unit. MethodsRetrospective analysis of all WtL entries registered in our anonymized clinical registry, from October 2018 to September 2020. ResultsOne-hundred and twelve patients were included: 53% were male, average age was 66 years old; 88% had malignancies, with a mean performance status of 55%. Mean for WtL of was 3.26 (SD = 3.87) with a prevalence of 60.7% strong, 8.9% moderate and 30.4% weak WtL. Weaker WtL was observed among patients who were not well adapted to their disease (P = .001), felt a burden to others (P< .001), were depressed (P = .001), anxious (P< .001) and endorsed a desire for death (P< .001). Weaker WtL was associated with pain (P = .002) and lower well-being (P = .001). Results from the logistic regression model found that the adaptation to disease emerged as a significant predictor of WtL (P = .025), and burden to others remained marginally significant (P = .087). ConclusionThe factors associated with lower WtL scores are consistent with previous studies, indicating that these patients experience a myriad of physical, psychological and existential symptoms requiring an interdisciplinary palliative care approach. These factors pertaining to WtL should be made known, as Portugal considers how to navigate death-hastening legislation.

Access to palliative care services for limited English proficient patients with advanced NSCLC.

99 Background: More than a quarter of people living in British Columbia, Canada speak languages other than English in their homes. Immigrants often encounter communication challenges with their health care providers (HCPs), have poor health literacy, and have a limited understanding on navigating the health care system. NSCLC patients with limited English proficiency (LEP) may receive less palliative care services despite high symptom burden and significant needs due to these factors. The study goals were to observe the difference in access to community palliative home care (CPHC) and rate of completing a Do Not Resuscitate (DNR) form between NSCLC patients who are English proficient (EP) and LEP. Methods: All patients with advanced NSCLC referred to BC Cancer–Vancouver Centre in 2016 and received medical care were included (N=176). Patients seen with a medical interpreter were considered to be LEP. Demographics and clinical information were collected retrospectively. UVA using X2 test and Fisher’s exact test were used to compare EP and LEP patients. Mann-Whitney test was used to compare the median time from CPHC referral and signed DNR to death between EP and LEP patients. Results: Language of communication: English 65%, Cantonese 22%, Mandarin 6%, Korean 1%, Tagalog 1%, and other 5%. Baseline characteristics: median age 69 EP vs 76 LEP, female 44% EP vs 65% LEP, non-squamous 68% EP vs 72% LEP and squamous 14% EP vs 6% LEP. There was no difference in the rate of CPHC referral (87% EP vs 80% LEP, p=0.342) and signed DNR form (92% EP vs 89% LEP, p=0.549). The median time from CPHC referral to death was 10 weeks EP vs 15 weeks LEP (p=0.039). The median time from signed DNR to death was 5 weeks EP vs 6 weeks LEP (p=0.806). There was no statistically significant difference in location of death between the two groups: acute care 20% EP vs 24% LEP, home 27% EP vs 13% LEP, hospice 36% EP vs 39% LEP, and tertiary palliative care unit 17% EP vs 24% LEP (p=0.251). Conclusions: EP and LEP patients with NSCLC had similar rates of CPHC service referrals and end of life planning. This suggests assistance of medical interpreters at the time of oncology visits help message delivery between LEP patients and HCPs. LEP patients had earlier referrals to CPHC prior to death which may reflect an enhanced awareness and effort by HCPs to have earlier conversations with patients who may have language and cultural barriers with discussing goals of care. Good communication improves patients and their family’s understanding of the goals and scope of palliative care services and allow HCPs to better understand the patients’ wishes.

The desire for death in Portuguese home-care palliative patients: Retrospective analysis of the prevalence and associated factors.

Desire for death (DfD) is a complex and multifactorial dimension of end-of-life experience. We aimed to evaluate the prevalence of DfD and its associations, arising within the setting of a tertiary home-based palliative care (PC) unit. Retrospective analysis of all DfD entries registered in our anonymized database from October 2018 to April 2020. Of the 163 patients anonymously registered in our database, 122 met entry criteria; 52% were male, the average age was 69 years old; 85% had malignancies, with a mean performance status (PPS) of 56%. The prevalence of DfD was 20%. No statistical differences were observed between patients with and without DfD regarding sex, age, marital status, religion, social support, prior PC or psychological follow-up, type of diagnosis, presence of advanced directives/living will, time since diagnosis and PC team's follow-up time. Statistically significant associations were found between higher PPS scores and DfD (OR = 0.96; 95% confidence interval (CI) [0.93-0.99]); Edmonton Symptom Assessment Scale scores for drowsiness (OR = 4.05; 95% CI [1.42-11.57]), shortness of breath (OR = 3.35; 95% CI [1.09-10.31]), well-being (OR = 7.64; 95% CI [1.63-35.81]). DfD was associated with being depressed (OR = 19.24; 95% CI [3.09-+inf]); feeling anxious (OR = 11.11; 95% CI [2.51-49.29]); HADS anxiety subscale ≥11 (OR = 25.0; 95% CI [2.10-298.29]); will-to-live (OR = 39.53; 95% CI [4.85-321.96]). Patients feeling a burden were more likely to desire death (OR = 14.67; 95% CI [1.85-116.17]), as well as those who were not adapted to the disease (OR = 4.08; 95% CI [1.30-12.84]). In multivariate regression analyses predicting DfD, three independent factors emerged: higher PPS scores were associated with no DfD (aOR = 0.95; 95% CI [0.91-0.99]), while the sense of being a burden (aOR = 12.82; 95% CI [1.31-125.16]) and worse well-being (aOR = 7.72; 95% CI [1.26-47.38]) predicted DfD. Prevalence of DfD was 20% and consistent with previous Portuguese evidence on DfD in PC inpatients. Both physical and psychosocial factors contribute to a stronger DfD.

Art Therapy in a Palliative Care Unit: Symptom Relief and Perceived Helpfulness in Patients and Their Relatives

ContextCreative arts therapies aim to expand conventional palliative care interventions by making clinical care more holistic. ObjectivesThe objective of the present study was to evaluate the benefits of an art therapy intervention in a tertiary hospital palliative care unit, directly in adult cancer inpatients and indirectly in their relatives. MethodsWe evaluated the intensity of pain, anxiety, depression, and well-being using the Edmonton Symptom Assessment Scale before and after the first, third, and fifth art therapy sessions. After the third and fifth sessions, perceived helpfulness was assessed via a questionnaire developed by the palliative care team, combining open-ended questions and a checklist. We categorized the narrative data into three predetermined types: generally helpful (some positive experience), helpfulness related to a dyadic relationship (patient-art therapist), and helpfulness related to a triadic relationship (patient-image-art therapist). ResultsWe observed a significant reduction in anxiety, depression, and pain as well as a significant increase in well-being at each of the time points evaluated. Ninety-eight percent of the patients considered the art therapy helpful, which could be categorized as generally helpful in 54.8%, related to a triadic relationship in 32.9%, and to a dyadic relationship in 12.3%. Relatives gave similar opinions regarding the effects on patients and, in addition, reported an indirect helpful effect for themselves. The most frequently selected experiences from the checklist were feeling calm, being entertained, and expressing and communicating emotions. ConclusionThis art therapy intervention was beneficial in reducing symptom intensity. Almost all the participants directly or indirectly involved in the creative art process considered it helpful. They reported a wide variety of sensory, emotional, cognitive, and spiritual experiences.

A Retrospective Thematic Analysis of Patient, Family, and Staff Creative Art Tiles Developed on a Tertiary Palliative Care Unit.

Clinical use of the creative arts in palliative care is well established, yet there are few evaluation studies of these programs. In this first phase of a 3-phase evaluation of a creative arts program entitled "Tile Tales," we conducted a retrospective thematic analysis of 85 painted tiles and accompanying stories that were publically displayed on a tertiary palliative care unit. Each story was independently coded, using content analysis. Themes were derived through consensus, using the constant comparative method. Tiles were created by staff (n = 36, 42%), family (n = 32, 38%), patients (n = 9, 11%), or patients and family (n = 8, 9%). Six major themes emerged from the artwork: "Spirituality," "Relationships," "Journey," "Story," "Symbolism," and "Paradox." These results illustrate how the creative arts can support the expression of diverse palliative care experiences, for patients, their families and palliative care staff, when words alone may not suffice.

Comparing the physical, psychological, social, and spiritual needs of patients with non-cancer and cancer diagnoses in a tertiary palliative care setting.

The purpose was to describe the physical, psychological, social, and spiritual needs of patients with non-cancer serious illness diagnoses compared to those of patients with cancer. We conducted a retrospective chart review of all patients with a non-cancer diagnosis admitted to a tertiary palliative care unit between January 2008 and December 2017 and compared their needs to those of a matched cohort of patients with cancer diagnoses. The prevalence of needs within the following four main concerns was recorded and the data analyzed using descriptive statistics and content analysis: •Physical: pain, dyspnea, fatigue, anorexia, edema, and delirium•Psychological: depression, anxiety, prognosis, and dignity•Social: caregiver burden, isolation, and financial•Spiritual: spiritual distress. The prevalence of the four main concerns was similar among patients with non-cancer and cancer diagnoses. Pain, nausea/vomiting, fatigue, and anorexia were more prevalent among patients with cancer. Dyspnea was more commonly the primary concern in patients with non-cancer diagnoses (39%), who also had a higher prevalence of anxiety and concerns about dignity. Spirituality was addressed more often in patients with cancer. The majority of patients admitted to tertiary palliative care settings have historically been those with cancer. The tertiary palliative care needs of patients with non-cancer diagnoses have not been well described, despite the increasing prevalence of this population. Our description of the palliative care needs of patients with non-cancer diagnoses will help guide future palliative care for the increasing population of patients with non-cancer serious illness diagnoses.

Development and evaluation of an innovative creative arts program on a tertiary palliative care unit.

167 Background: The use of creative arts in palliative care is a unique psychosocial-spiritual intervention, yet there are limited evaluation studies of these programs. The purpose of this presentation is to describe the development and evaluation of a creative arts program, entitled “Tile Tales,” on a 20-bed tertiary palliative care unit. Methods: The “Tile Tales” program encourages the creative exploration of emotions, values and beliefs through the creation of a visual expression on a ceramic tile, with an accompanying story. In this second phase of a three-phase evaluation, participants (18 years or older) were asked to complete a survey at the end of their experience. Results: Over a two-year period (January, 2016 – December, 2017), 40 tiles were completed by 52 participants. Children under 18 years (n = 16) were excluded from further analysis. Twenty-one of 36 adult participants (58%) completed surveys, consisting of family members (n = 9, 43%), patients (n = 6, 28.5%) and staff (n = 6, 28.5%). Participants rated their experience as very meaningful (M 4.8, SD 0.5, scale 0-5). The three highest average impact scores (scale 0-5) were: raising spirits (M 4.9, SC 0.3), expression of feelings (M 4.6, SD .6) and working through grief (M 4.6, SD 0.7). Qualitative comments included themes of gratitude, leaving a legacy, meaning and connecting with others. Conclusions: This innovative creative arts program benefited patients, family and staff, in the expression of emotions and sharing personal stories. These findings will assist with improving program delivery and future planning of the creative arts in palliative care.

Single-Nucleotide Polymorphisms in TAOK3 Are Associated With High Opioid Requirement for Pain Management in Patients With Advanced Cancer Admitted to a Tertiary Palliative Care Unit

PurposeDifferent amounts of opioid are required for the relief of cancer pain in different individuals, raising the possibility that genetic factors play a role. We tested the hypothesis that genetic variations in the TAOK3 (TAO kinase 3, encoding serine/threonine-protein kinase) explain some of the interindividual variations related to the morphine-equivalent daily dose (MEDD) in patients with cancer. Experimental DesignWe selected two single-nucleotide polymorphisms (SNPs) in the TAOK3, reported earlier to associate with higher MEDD in postoperative pain based on genome-wide association study. We investigated their association with MEDD in Canadian patients with cancer (n = 110) admitted to a tertiary palliative care unit. SNPs analyzed were rs1277441 (C/T, C = minor allele) and rs795484 (A/G, A = minor allele). ResultsMinor allele frequencies in our population were 0.29 (rs1277441) and 0.28 (rs795484). These SNPs were in perfect linkage disequilibrium (r2 = 0.97). SNPs in TAOK3 showed a significant association with mean MEDD ≥800 mg. For rs795484, MEDD values ≥800 mg occurred in patients who were GG (7%), GA (18%), and AA (57%) (P = 0.004; Fisher's exact test); similar results were obtained for rs1277441. Homozygous variants for either SNP had received higher numbers of different opioids (P = 0.021). ConclusionIn this cohort of patients with advanced cancer pain, TAOK3 SNPs were associated with opioid doses. This result supports the original findings from a GWAS in postoperative patients. The proportions of variant homozygotes (8.2% of patients) and their requirement for higher doses of opioids would appear potentially clinically important and should be validated in further studies.

What is stable pain control? A prospective longitudinal study to assess the clinical value of a personalized pain goal

Background: A universal consensus regarding standardized pain outcomes does not exist. The personalized pain goal has been suggested as a clinically relevant outcome measure. Aim: To assess the feasibility of obtaining a personalized pain goal and to compare a clinically based personalized pain goal definition versus a research-based study definition for stable pain. Design: Prospective longitudinal descriptive study. Measures: The attending physician completed routine assessments, including a personalized pain goal and the Edmonton Classification System for Cancer Pain, and followed patients daily until stable pain control, death, or discharge. Stable pain for cognitively intact patients was defined as pain intensity less than or equal to desired pain intensity goal (personalized pain goal definition) or pain intensity ⩽3 (Edmonton Classification System for Cancer Pain study definition) for three consecutive days with <3 breakthroughs per day. Setting/participants: A total of 300 consecutive advanced cancer patients were recruited from two acute care hospitals and a tertiary palliative care unit. Results: In all, 231/300 patients (77%) had a pain syndrome; 169/231 (73%) provided a personalized pain goal, with 113/169 (67%) reporting a personalized pain goal ⩽3 (median = 3, range = 0–10). Using the personalized pain goal definition as the gold standard, sensitivity and specificity of the Edmonton Classification System for Cancer Pain definition were 71.3% and 98.5%, respectively. For mild (0–3), moderate (4–6), and severe (7–10) pain, the highest sensitivity was for moderate pain (90.5%), with high specificity across all three categories (95%–100%). Conclusion: The personalized pain goal is a feasible outcome measure for cognitively intact patients. The Edmonton Classification System for Cancer Pain definition closely resembles patient-reported personalized pain goals for stable pain and would be appropriate for research purposes. For clinical pain management, it would be important to include the personalized pain goal as standard practice.

Methadone as first-line opioid treatment for cancer pain in a developing country palliative care unit.

The use of methadone for cancer pain is limited by the need of expertise and close titration due to variable half-life. Yet, it is a helpful palliative strategy in low-resources countries given its long-acting effect at low cost and worth additional study. Our aim was to describe the prescription and outcomes of methadone as a first-line treatment for cancer pain in a tertiary palliative care unit (PCU) in Argentina. Retrospective review of medical records of patients with moderate to severe cancer pain seen at the PCU in 1-year period, who initiated strong opioids at the first consultation. Data collected during the first month of treatment included disease and pain characteristics, initial and final opioid type and dose and need for opioid rotation. Methadone was the most frequent opioid both at the initial and last assessment (71 and 66% of the prescriptions). In all, treatment with strong opioids provided considerable decrease in pain intensity (p<0.001) with low and stable opioid dose. Median and interquartile range (IR) of oral morphine equivalent daily dose (OMEDD) was 26 (16-32) and 39 (32-55)mg for initial and final assessments, respectively (p=0.3). In patients initiated with methadone, the median (IR) daily methadone dose was 5 (4-6)mg at first and 7.5 (6-10)mg at final assessment, and the median (IR) index of opioid escalation was 0 (0-4)mg; (p<0.05). Patients on methadone underwent less percentage of opioid rotation (15 versus 50%; p<0.001) and longer time to rotation (20.6±4.4 versus 9.0±2.7days; p<0.001) than patients on other opioids. Results indicate the preference of methadone as first-line strong opioid treatment in a PCU, providing good pain relief at low doses with low need for rotation. Several considerations about the costs of strong opioids in the region are given.

Hyponatremia as an independent prognostic factor in patients with terminal cancer.

Hyponatremia is a common and associated with poor clinical outcome in cancer patients. But little is known regarding hyponatremia in terminal cancer patients. The purpose of this study is to investigate the prognostic role of the hyponatremia in terminal cancer patients. A retrospective observational study was conducted between January 2010 and December 2012 in a tertiary hospital palliative care unit. Medical records were collected from hospitalized patients who were eligible for obtaining serum sodium level. Hyponatremia was defined as serum sodium <136 mEq/L. And we classified patients into three groups; eunatremia (sodium 136-145 mEq/L), mild to moderate hyponatremia (sodium 126-135 mEq/L), and severe hyponatremia (sodium ≤125 mEq/L). Univariate and multivariate Cox regression analyses were performed to determine factors affecting survival time. Of the 576 patients, hyponatremia was present in 367 individuals (63.7 %). In the univariate analysis, serum CRP, PPS, and sodium ≤125 mEq/L were associated with survival time (HR = 1.22; p < 0.001, HR = 0.69; p < 0.001, HR = 1.91; p < 0.001). In the multivariate analysis, serum CRP, PPS, sodium 126-135 mEq/L, and sodium ≤125 mEq/L were associated with survival time (HR = 1.16; p < 0.001, HR = 0.70; p < 0.001, HR = 1.19; p = 0.048, HR = 1.75; p < 0.001). Hyponatremia is an independent prognostic factor in terminal cancer patients and careful clinical concern is needed. In the future, large prospective study is warranted in terminal cancer patients.

Does gynecologic malignancy predict likelihood of a tertiary palliative care unit hospital admission? A comparison of local, provincial and national death rates

The purpose of this study was to determine whether the presence of gynecologic malignancies predicts the likelihood of a tertiary palliative care unit hospital admission. In this study, patients admitted to a specialized tertiary palliative care unit (TPCU) with gynecologic malignancies were compared to national and provincial death rates to determine if gynecologic malignancy predicts admission, and subsequent death, in a TPCU. Eighty-two gynecologic cancer patients were admitted to our TPCU over the 5- year study period. Out of all cancer deaths in the TPCU, death from ovarian cancer was 3.7% compared with 2.4% (p = 0.0068) of all cancer deaths in Manitoba and 2.3% (p = 0.0043) of all cancer deaths in Canada. Cervical cancer accounted for 1.7% of all our patients deaths compared with 0.7% (p = 0.0001) provincially and 0.6% (p = 0.0001) nationally. Uterine cancer deaths were not significantly different from the provincial and national death rates, whereas vulvar and fallopian cancers were too rare to allow for statistical analysis. Gynecologic cancers may be predictive of admission to a palliative care unit.

Exploring the Challenges of Implementing the Edmonton Symptom Assessment Scale in a Specialist Palliative Care Unit

Background: Many symptom assessment tools have been developed to aid evaluation of patient’s symptoms. The Edmonton Symptom Assessment Scale is one such tool. The ESAS was introduced on the inpatient unit in Milford Hospice (a 30 bedded tertiary palliative care unit) in December 2007. However, a 3-month chart review revealed a low completion rate (20%) of the ESAS. Aim: The aim of this study was to assess the reasons for the low completion rate of the ESAS in the unit. Methods: A mixed methods approach using both questionnaire and focus group was undertaken. The population sampled was the nursing staff who were responsible for ensuring the completion of the ESAS in the unit on a daily basis. Results: The main reason for the low completion rate of the ESAS was that nursing staff perceived that it was too burdensome for sick patients to complete (76%). Also, nursing staff felt that the tool was not clinically helpful and that it was too time consuming for patients to regularly complete. Other important issues relating to the introduction process for symptom assessment tools are also identified. Conclusions: The results of this study are consistent with findings in the literature relating to other symptom assessment tools. Implementing such tools may be burdensome for patients with a poor functional status in an advanced cancer setting. Areas of focus for further research include shorter symptom assessment tools which are more reflective of a patients twenty four hour symptom profile, and also proxy rated assessment tools.
