Estimated mortality risk and use of palliative care services among home care clients during the last 6 months of life: a retrospective cohort study.

BACKGROUND: In Canada, only 15% of patients requiring palliative care receive such services in the year before death. We describe health care utilization patterns among home care users in their last 6 months of life to inform care planning for older people with varying mortality risks and evolving care needs as they decline. METHODS: Using population health administrative data from Ontario, we performed a retrospective cohort study involving home care clients aged 50 years and older who received at least 1 interRAI (Resident Assessment Instrument) Home Care assessment between April 2018 and September 2019. We report the proportion of clients who used acute care, long-term care, and palliative home care services within 6 months of their assessment, stratified by their predicted 6-month mortality risk using a prognostic tool called the Risk Evaluation for Support: Predictions for Elder-life in their Communities Tool (RESPECT) and vital status. RESULTS: The cohort included 247 377 adults, 11.9% of whom died within 6 months of an assessment. Among decedents, 50.6% of those with a RESPECT-estimated median survival of fewer than 3 months received at least 1 nonphysician palliative home care visit before death. This proportion declined to 38.7% and 29.5% among decedents with an estimated median survival between 3 and 6 months and between 6 and 12 months, respectively. INTERPRETATION: Many older adults in Ontario do not receive any palliative home care before death. Prognostic tools such as RESPECT may improve recognition of reduced life expectancies and palliative care needs of individuals in their final years of life.

Ascertaining the Francophone population in Ontario: validating the language variable in health data.

BACKGROUND: Language barriers can impact health care and outcomes. Valid and reliable language data is central to studying health inequalities in linguistic minorities. In Canada, language variables are available in administrative health databases; however, the validity of these variables has not been studied. This study assessed concordance between language variables from administrative health databases and language variables from the Canadian Community Health Survey (CCHS) to identify Francophones in Ontario. METHODS: An Ontario combined sample of CCHS cycles from 2000 to 2012 (from participants who consented to link their data) was individually linked to three administrative databases (home care, long-term care [LTC], and mental health admissions). In total, 27,111 respondents had at least one encounter in one of the three databases. Language spoken at home (LOSH) and first official language spoken (FOLS) from CCHS were used as reference standards to assess their concordance with the language variables in administrative health databases, using the Cohen kappa, sensitivity, specificity, positive predictive value (PPV), and negative predictive values (NPV). RESULTS: Language variables from home care and LTC databases had the highest agreement with LOSH (kappa = 0.76 [95%CI, 0.735-0.793] and 0.75 [95%CI, 0.70-0.80], respectively) and FOLS (kappa = 0.66 for both). Sensitivity was higher with LOSH as the reference standard (75.5% [95%CI, 71.6-79.0] and 74.2% [95%CI, 67.3-80.1] for home care and LTC, respectively). With FOLS as the reference standard, the language variables in both data sources had modest sensitivity (53.1% [95%CI, 49.8-56.4] and 54.1% [95%CI, 48.3-59.7] in home care and LTC, respectively) but very high specificity (99.8% [95%CI, 99.7-99.9] and 99.6% [95%CI, 99.4-99.8]) and predictive values. The language variable from mental health admissions had poor agreement with all language variables in the CCHS. CONCLUSIONS: Language variables in home care and LTC health databases were most consistent with the language often spoken at home. Studies using language variables from administrative data can use the sensitivity and specificity reported from this study to gauge the level of mis-ascertainment error and the resulting bias.

Building evidence to advance health equity: a systematic review on care-related outcomes for older, minoritised populations in long-term care homes.

BACKGROUND: Advancing health equity requires more contextualised evidence. OBJECTIVES: To synthesise published evidence using an existing framework on the origins of health disparities and determine care-related outcome disparities for residents of long-term care, comparing minoritised populations to the context-specific dominant population. DESIGN: Systematic review. SUBJECTS: Residents of 24-hour long-term care homes. METHODS: The protocol was registered a priori with PROSPERO (CRD42021269489). Literature published between 1 January 2000 and 26 September 2021, was searched, including studies comparing baseline characteristics and outcomes in minoritised versus dominant populations. Dual screening, two-reviewer verification for extraction, and risk of bias assessments were conducted to ensure rigour. Studies were synthesized using a conceptual framework to contextualise evidence according to multi-level factors contributing to the development of care disparities. RESULTS: Twenty-one of 34 included studies demonstrated disparities in care outcomes for minoritised groups compared to majority groups. Thirty-one studies observed differences in individual-level characteristics (e.g. age, education, underlying conditions) upon entry to homes, with several outcome disparities (e.g. restraint use, number of medications) present at baseline and remaining or worsening over time. Significant gaps in evidence were identified, particularly an absence of literature on provider information and evidence on the experience of intersecting minority identities that contribute to care-related outcome disparities in long-term care. CONCLUSION: This review found differences in minoritised populations' care-related outcomes. The findings provide guidance for future health equity policy and research-supporting diverse and intersectional capacity building in long-term care.

Initial treatment is associated with improved survival and end-of-life outcomes for patients with pancreatic cancer: a cohort study.

BACKGROUND: We describe the association between initial treatment and end-of-life (EOL) outcomes among patients with pancreatic ductal adenocarcinoma (PDAC). METHODS: This population-based cohort study included patients with PDAC who died from April 2010-December 2017 in Ontario, Canada using administrative databases. We used multivariable models to explore the association between index cancer treatment (no cancer-directed therapy, radiation, chemotherapy, surgery alone, and surgery and chemotherapy), and primary (mortality, healthcare encounters and palliative care) and secondary outcomes (location of death, hospitalizations, and receipt of chemotherapy within the last 30 days of life). RESULTS: In our cohort (N = 9950), 56% received no cancer-directed therapy, 5% underwent radiation, 27% underwent chemotherapy, 7% underwent surgery alone, and 6% underwent surgery and chemotherapy. Compared to no cancer-directed therapy, radiation therapy (HR = 0.63), chemotherapy (HR = 0.43) surgery alone (HR = 0.32), and surgery and chemotherapy (HR = 0.23) were all associated with decreased mortality. Radiation (AMD = - 3.64), chemotherapy (AMD = -6.35), surgery alone (AMD = -6.91), and surgery and chemotherapy (AMD = -6.74) were all associated with fewer healthcare encounters per 30 days in the last 6 months of life. Chemotherapy (AMD = -1.57), surgery alone (AMD = -1.65), and surgery and chemotherapy (AMD = -1.67) were associated with fewer palliative care visits (all p-values for estimates above < 0.05). Treatment groups were associated with lower odds of institutional death and hospitalization at EOL, and higher odds of chemotherapy at EOL. CONCLUSIONS: Receiving cancer-directed therapies was associated with higher survival, fewer healthcare visits, lower odds of dying in an institution and hospitalization at EOL, fewer palliative care visits, and higher odds of receiving chemotherapy at EOL.

Using Patient Simulation to Promote Best Practices in Fall Prevention and Postfall Assessment in Nursing Homes.

BACKGROUND: Fall-related injuries rise with age and are of particular concern for frail populations living in nursing homes. LOCAL PROBLEM: The Perley and Rideau Veterans' Health Centre is a large nursing home in Ontario, Canada. In 2019, we conducted internal audits of our Falls Prevention Program and identified notable variations in staff's response to a resident fall. INTERVENTIONS: We developed an in situ patient simulation program of a resident fall. METHODS: This was a mixed-methods evaluation of participants' perspectives of a simulation-based interprofessional education program for fall prevention. RESULTS: Participants indicated high-level support for simulation-based learning, with more than 80% of the participants expressing that they will apply these skills in the future when caring for a resident who falls. CONCLUSIONS: Our findings indicate that simulation-based training is well received by frontline workers in a nursing home setting and can be conducted as part of a typical shift with minimal disruption to resident care.

Pandemic Preparedness and Beyond: Person-Centred Care for Older Adults Living in Long-Term Care during the COVID-19 Pandemic.

The increasing complexity of residents' needs, emphasis on social distancing and limited access to high-quality support presented challenges to patient-centred care during the pandemic. Yet the pandemic created an opportunity to explore novel approaches to achieving person-centred care within long-term care (LTC). We share three projects designed to enhance care delivery in the context of the pandemic: to address personhood needs during outbreaks, to improve the quality of medical care and to deliver personalized palliative and end-of-life care using a prediction algorithm. These projects enabled better care during the pandemic and will continue to advance person-centred care beyond the pandemic.

Immediate and Long-Term Health Care Support Needs of Older Adults Undergoing Cancer Surgery: A Population-Based Analysis of Postoperative Homecare Utilization.

BACKGROUND: Functional outcomes are central to decision-making by older adults (OA), but long-term risks after cancer surgery have not been described beyond 1 year for this population. This study aimed to evaluate long-term health care support needs by examining homecare use after cancer surgery for OA. METHODS: This population-based study investigated adults 70 years of age or older with a new cancer diagnosis between 2007 and 2017 who underwent resection. The outcomes were receipt and intensity of homecare from postoperative discharge to 5 years after surgery. Time-to-event analysis with competing events was used. RESULTS: Among 82,037 patients, homecare use was highest (43.7% of eligible patients) in postoperative month 1. The need for homecare subsequently decreased to stabilize between year 1 (13.9%) and year 5 (12.6%). Of the patients not receiving preoperative homecare, 10.9% became long-term users at year 5 after surgery. Advancing age, female sex, frailty, high-intensity surgery, more recent period of surgery, and receipt of preoperative homecare were associated with increased hazards of postoperative homecare. Intensity of homecare went from 10.3 to 10.1 days per patient-month between month 1 and year 1, reaching 12 days per patient-month at year 5. The type of homecare services changed from predominantly nursing care in year 1 (51.9%) to increasing personal support services from year 2 (69.6%) to year 5 (77.5%). CONCLUSION: Receipt of homecare increased long-term after cancer surgery for OA, peaking in the first 6 months and plateauing thereafter at a new baseline. One tenth of the patients without preoperative homecare became long-term homecare users postoperatively, indicating changing health care needs focused on personal support services from year 2 to year 5.

Predicting death in home care users: derivation and validation of the Risk Evaluation for Support: Predictions for Elder-Life in the Community Tool (RESPECT).

BACKGROUND: Prognostication tools that report personalized mortality risk and survival could improve discussions about end-of-life and advance care planning. We sought to develop and validate a mortality risk model for older adults with diverse care needs in home care using self-reportable information - the Risk Evaluation for Support: Predictions for Elder-Life in the Community Tool (RESPECT). METHODS: Using a derivation cohort that comprised adults living in Ontario, Canada, aged 50 years and older with at least 1 Resident Assessment Instrument for Home Care (RAI-HC) record between Jan. 1, 2007, and Dec. 31, 2012, we developed a mortality risk model. The primary outcome was mortality 6 months after a RAI-HC assessment. We used proportional hazards regression with robust standard errors to account for clustering by the individual. We validated this algorithm for a second cohort of users of home care who were assessed between Jan. 1 and Dec. 31, 2013. We used Kaplan-Meier survival curves to estimate the observed risk of death at 6 months for assessment of calibration and median survival. We constructed 61 risk groups based on incremental increases in the estimated median survival of about 3 weeks among adults at high risk and 3 months among adults at lower risk. RESULTS: The derivation and validation cohorts included 435 009 and 139 388 adults, respectively. We identified a total of 122 823 deaths within 6 months of a RAI-HC assessment in the derivation cohort. The mean predicted 6-month mortality risk was 10.8% (95% confidence interval [CI] 10.7%-10.8%) and ranged from 1.54% (95% CI 1.53%-1.54%) in the lowest to 98.1% (95% CI 98.1%-98.2%) in the highest risk group. Estimated median survival spanned from 28 days (11 to 84 d at the 25th and 75th percentiles) in the highest risk group to over 8 years (1925 to 3420 d) in the lowest risk group. The algorithm had a c-statistic of 0.753 (95% CI 0.750-0.756) in our validation cohort. INTERPRETATION: The RESPECT mortality risk prediction tool that makes use of readily available information can improve the identification of palliative and end-of-life care needs in a diverse older adult population receiving home care.

Frailty Is Associated With Decreased Time Spent at Home After Critical Illness: A Population-Based Study.

BACKGROUND: Frailty is characterized by vulnerability to stressors due to an accumulation of multiple functional deficits. Frailty is increasingly recognized as a risk factor for accelerated functional decline, increasing dependency, and risk of mortality. The objective of this study was to examine the association of frailty, at the time of critical care admission, with days alive at home and health care costs post-discharge. METHODS: This retrospective cohort study used linked administrative data (2010-2016) in Ontario, Canada. We identified all patients admitted at the intensive care unit (ICU), aged 19 years and above, assessed using the Resident Assessment Instrument for Home Care (RAI-HC), within 6 months prior to index hospitalization including an ICU stay. Patients were stratified as robust, pre-frail, or frail based on a validated Frailty Index. The primary outcome was days alive at home in the year after admission. Secondary outcomes included mortality, health care-associated costs, ICU interventions, long-term care admissions, and hospital readmissions. RESULTS: Frail patients spent significantly fewer days at home within 1 year of index hospitalization (mean 159 days vs 223 days in robust cohort, P < .001). Mortality was higher among frail patients at 1 year (59.6% in the frail cohort vs 45.9% in robust patients; odds ratio for death 1.59 [1.49-1.69]). Frail patients also had higher rates of long-term care admission within 1 year (30.1% vs 10.6% in robust patients). Total health care-associated costs per person alive were $30 450 higher the year after admission in the frail cohort. CONCLUSIONS: Frailty prior to ICU admission among patients who were eligible for RAI-HC assessment was associated with higher mortality and fewer days spent at home following admission. Frail patients had markedly higher rates of long-term care admission and increased costs per life saved following critical illness. These findings add to the discussion of risk-benefit trade-offs for ICU admission.

Examining the course of transitions from hospital to home-based palliative care: A mixed methods study.

BACKGROUND: Hospital-to-home transitions in palliative care are fraught with challenges. To assess transitions researchers have used patient reported outcome measures and qualitative data to give unique insights into a phenomenon. Few measures examine care setting transitions in palliative care, yet domains identified in other populations are likely relevant for patients receiving palliative care. AIM: Gain insight into how patients experience three domains, discharge readiness, transition quality, and discharge-coping, during hospital-to-home transitions. DESIGN: Longitudinal, convergent parallel mixed methods study design with two data collection visits: in-hospital before and 3-4 weeks after discharge. Participants completed scales assessing discharge readiness, transition quality, and post discharge-coping. A qualitative interview was conducted at both visits. Data were analyzed separately and integrated using a merged transformative methodology, allowing us to compare and contrast the data. SETTING AND PARTICIPANTS: Study was set in two tertiary hospitals in Toronto, Canada. Adult inpatients (n = 25) and their caregivers (n = 14) were eligible if they received a palliative care consultation and transitioned to home-based palliative care. RESULTS: Results were organized aligning with the scales; finding low discharge readiness (5.8; IQR: 1.9), moderate transition quality (66.7; IQR: 33.33), and poor discharge-coping (5.0; IQR: 2.6), respectively. Positive transitions involved feeling well supported, managing medications, feeling well, and having healthcare needs met. Challenges in transitions were feeling unwell, confusion over medications, unclear healthcare responsibilities, and emotional distress. CONCLUSIONS: We identified aspects of these three domains that may be targeted to improve transitions through intervention development. Identified discrepancies between the data types should be considered for future research exploration.

Impact of physician-based palliative care delivery models on health care utilization outcomes: A population-based retrospective cohort study.

BACKGROUND: Increasing involvement of palliative care generalists may improve access to palliative care. It is unknown, however, if their involvement with and without palliative care specialists are associated with different outcomes. AIM: To describe physician-based models of palliative care and their association with healthcare utilization outcomes including: emergency department visits, acute hospitalizations and intensive care unit (ICU) admissions in last 30 days of life; and, place of death. DESIGN: Population-based retrospective cohort study using linked health administrative data. We used descriptive statistics to compare outcomes across three models (generalist-only palliative care; consultation palliative care, comprising of both generalist and specialist care; and specialist-only palliative care) and conducted a logistic regression for community death. SETTING/PARTICIPANTS: All adults aged 18-105 who died in Ontario, Canada between April 1, 2012 and March 31, 2017. RESULTS: Of the 231,047 decedents who received palliative services, 40.3% received generalist, 32.3% consultation and 27.4% specialist palliative care. Across models, we noted minimal to modest variation for decedents with at least one emergency department visit (50%-59%), acute hospitalization (64%-69%) or ICU admission (7%-17%), as well as community death (36%-40%). In our adjusted analysis, receipt of a physician home visit was a stronger predictor for increased likelihood of community death (odds ratio 9.6, 95% confidence interval 9.4-9.8) than palliative care model (generalist vs consultation palliative care 2.0, 1.9-2.0). CONCLUSION: The generalist palliative care model achieved similar healthcare utilization outcomes as consultation and specialist models. Including a physician home visit component in each model may promote community death.

Association between high cost user status and end-of-life care in hospitalized patients: A national cohort study of patients who die in hospital.

BACKGROUND: Studies comparing end-of-life care between patients who are high cost users of the healthcare system compared to those who are not are lacking. AIM: The objective of this study was to describe and measure the association between high cost user status and several health services outcomes for all adults in Canada who died in acute care, compared to non-high cost users and those without prior healthcare use. SETTINGS AND PARTICIPANTS: We used administrative data for all adults who died in hospital in Canada between 2011 and 2015 to measure the odds of admission to the intensive care unit (ICU), receipt of invasive interventions, major surgery, and receipt of palliative care during the hospitalization in which the patient died. High cost users were defined as those in the top 10% of acute healthcare costs in the year prior to a person's hospitalization in which they died. RESULTS: Among 252,648 people who died in hospital, 25,264 were high cost users (10%), 112,506 were non-high cost users (44.5%) and 114,878 had no prior acute care use (45.5%). After adjustment for age and sex, high cost user status was associated with a 14% increased odds of receiving an invasive intervention, a 15% increased odds of having major surgery, and an 8% lower odds of receiving palliative care compared to non-high cost users, but opposite when compared to patients without prior healthcare use. CONCLUSIONS: Many patients receive aggressive elements of end-of-life care during the hospitalization in which they die and a substantial number do not receive palliative care. Understanding how this care differs between those who were previously high- and non-high cost users may provide an opportunity to improve end of life care for whom better care planning and provision ought to be an equal priority.

The association between varying levels of palliative care involvement on costs during terminal hospitalizations in Canada from 2012 to 2015.

BACKGROUND: Inpatient palliative care is associated with lower inpatient costs; however, this has yet to be studied using a more nuanced, multi-tiered measure of inpatient palliative care and a national population-representative dataset. Using a population-based cohort of Canadians who died in hospital, our objectives were to: describe patients' receipt of palliative care and active interventions in their terminal hospitalization; and examine the relationship between inpatient palliative care and hospitalization costs. METHODS: Retrospective cohort study using data from the Discharge Abstract Database in Canada between fiscal years 2012 and 2015. The cohort were Canadian adults (age ≥ 18 years) who died in hospital between April 1st, 2012 and March 31st, 2015 (N = 250,640). The exposure was level of palliative care involvement defined as: medium-high, low, or no palliative care. The main measure was acute care costs calculated using resource intensity weights multiplied by the cost of standard hospital stay, represented in 2014 Canadian dollars (CAD). Descriptive statistics were represented as median (IQR), and n(%). We modelled cost as a function of palliative care using a gamma generalized estimating equation (GEE) model, accounting for clustering by hospital. RESULTS: There were 250,640 adults who died in hospital. Mean age was 76 (SD 14), 47% were female. The most common comorbidities were: metastatic cancer (21%), heart failure (21%), and chronic obstructive pulmonary disease (16%). Of the decedents, 95,450 (38%) had no palliative care involvement, 98,849 (38%) received low involvement, and 60,341 (24%) received medium to high involvement. Controlling for age, sex, province and predicted hospital mortality risk at admission, the cost per day of a terminal hospitalization was: $1359 (95% CI 1323: 1397) (no involvement), $1175 (95% CI 1146: 1206) (low involvement), and $744 (95% CI 728: 760) (medium-high involvement). CONCLUSIONS: Increased involvement of palliative care was associated with lower costs. Future research should explore whether this relationship holds for non-terminal hospitalizations, and whether palliative care in other settings impacts inpatient costs.

Cost-effectiveness of Investment in End-of-Life Home Care to Enable Death in Community Settings.

BACKGROUND: Many people with terminal illness prefer to die in home-like settings-including care homes, hospices, or palliative care units-rather than an acute care hospital. Home-based palliative care services can increase the likelihood of death in a community setting, but the provision of these services may increase costs relative to usual care. OBJECTIVE: The aim of this study was to estimate the incremental cost per community death for persons enrolled in end-of-life home care in Ontario, Canada, who died between 2011 and 2015. METHODS: Using a population-based cohort of 50,068 older adults, we determined the total cost of care in the last 90 days of life, as well as the incremental cost to achieve an additional community death for persons enrolled in end-of-life home care, in comparison with propensity score-matched individuals under usual care (ie, did not receive home care services in the last 90 days of life). RESULTS: Recipients of end-of-life home care were nearly 3 times more likely to experience a community death than individuals not receiving home care services, and the incremental cost to achieve an additional community death through the provision of end-of-life home care was CAN$995 (95% confidence interval: -$547 to $2392). CONCLUSION: Results suggest that a modest investment in end-of-life home care has the potential to improve the dying experience of community-dwelling older adults by enabling fewer deaths in acute care hospitals.

Five-year risk of admission to long-term care home and death for older adults given a new diagnosis of dementia: a population-based retrospective cohort study.

BACKGROUND: After diagnosis of a health condition, information about survival and potential transition from community into institutional care can be helpful for patients and care providers. We sought to describe the association between a new diagnosis of dementia and risk of admission to a long-term care home and death at 5 years. METHODS: We conducted a population-based retrospective cohort study using linked health administrative databases. We identified individuals aged 65 years or older, living in the community, with a first documented diagnosis of dementia between Jan. 1, 2010, and Dec. 31, 2012, in Ontario, Canada. Dementia diagnosis was captured using diagnostic codes from hospital discharges, physician billings, assessments conducted for home care and long-term care, and dispensed prescriptions for cholinesterase inhibitors. Our primary outcome measures were 5-year risk of death and placement in a long-term care home, adjusted for sociodemographic and clinical factors. RESULTS: We identified 108 757 individuals in our study cohort. By the end of 5 years, 24.4% remained alive in the community and 20.5% were living in a long-term care home. Of the 55.1% who died, about half (27.9%) were admitted to a long-term care home before death. Three risk factors were associated with increased odds of death: older age (age ≥ 90 yr; odds ratio [OR] 9.5, 95% confidence interval [CI] 8.8-10.2 [reference: age 65-69 yr]), male sex (OR 1.7, 95% CI 1.6-1.7), and the presence of organ failure, including chronic obstructive pulmonary disease (OR 1.7, 95% CI 1.7-1.8), congestive heart failure (OR 2.0, 95% CI 1.9-2.0) and renal failure (OR 1.7, 95% CI 1.6-1.8). Groups formed by combinations of these 3 factors had an observed 5-year risk of death varying between 22% and 91%. INTERPRETATION: Among community-dwelling older adults with newly identified dementia in Ontario, the majority died or were admitted to a long-term care home within 5 years. This information may be helpful for discussions on prognosis and need for admission to long-term care.

Economic evaluations of palliative care models: A systematic review.

BACKGROUND: Palliative care aims to improve quality of life by relieving physical, emotional, and spiritual suffering. Health system planning can be informed by evaluating cost and effectiveness of health care delivery, including palliative care. AIM: The objectives of this article were to describe and critically appraise economic evaluations of palliative care models and to identify cost-effective models in improving patient-centered outcomes. DESIGN: We conducted a systematic review and registered our protocol in PROSPERO (CRD42016053973). DATA SOURCES: A systematic search of nine medical and economic databases was conducted and extended with reference scanning and gray literature. Methodological quality was assessed using the Drummond checklist. RESULTS: We identified 12,632 articles and 5 were included. We included two modeling studies from the United States and England, and three economic evaluations from England, Australia, and Italy. Two studies compared home-based palliative care models to usual care, and one compared home-based palliative care to no care. Effectiveness outcomes included hospital readmission prevented, days at home, and palliative care symptom severity. All studies concluded that palliative care was cost-effective compared to usual care. The methodological quality was good overall, but three out of five studies were based on small sample sizes. CONCLUSION: Applicability and generalizability of evidence is uncertain due to small sample sizes, short duration, and limited modeling of costs and effects. Further economic evaluations with larger sample sizes are needed, inclusive of the diversity and complexity of palliative care populations and using patient-centered outcomes.

Does inpatient palliative care consultation impact outcomes following hospital discharge? A narrative systematic review.

BACKGROUND: While most patients desire to die at home or in a community-based hospice, the transition from hospital to community settings often lacks streamlined coordination of care to ensure that adequate support is provided in the preferred care setting. The impact of hospital-based palliative care consultations on post-discharge care and outcomes has not been extensively studied. AIM: The aim of this study was to appraise available research on the impact of inpatient palliative care consultations on transitions from hospital to community settings. DESIGN: We conducted a narrative systematic review and used the Effective Public Health Practice Project tool to appraise the quality of selected studies. Studies were included if they assessed the transition from hospital to community and examined outcomes after an inpatient palliative care consultation. A protocol for this study was registered and published in PROSPERO, Centre for Reviews and Dissemination (ID: CRD42018094924). DATA SOURCES: We searched for quantitative studies indexed in PubMED, CINAHL and Cochrane and published between 1 January 1 2000 and 11 March 2018. RESULTS: Our search retrieved 2749 articles. From these, 123 articles were full-text screened and 15 studies met our inclusion criteria. Studies reported that inpatient palliative care consultations are associated with high rates of discharge to community settings, greater provision of services post-discharge, improved coordination and lower rates of rehospitalization. CONCLUSION: Existing evidence suggest that inpatient palliative care consultations have a positive impact on patient outcomes and transitions to the community, demonstrating the potential to improve patient quality of life and relieve overburdened acute care systems.

Associations between the receipt of inpatient palliative care and acute care outcomes: A retrospective study.

BACKGROUND: Palliative care (PC) has been shown to improve outcomes for individuals at the end of life. Despite this, many Canadians do not receive PC prior to death. The present study examines the receipt of inpatient PC and its association with location of death, as well as with admission to intensive care units (ICUs) and use of alternate level of care (ALC) beds in hospital in the last 30 days of life. DATA AND METHODS: The study sample is a retrospective cohort of adult Canadians (aged 19 and older) who died between April 1, 2010, and December 31, 2014. Deaths were ascertained from the Canadian Vital Statistics Database and linked to hospitalizations records in the Discharge Abstract Database to identify the receipt of inpatient PC. RESULTS: More than half (57.7%) of Canadian adults died in hospital, with only 12.6% receiving any inpatient PC in the year prior to death, and 1.7% receiving a preterminal PC designation (i.e., PC initiated prior to the last 30 days of life). In the adjusted analyses, receipt of any inpatient PC was associated with a higher likelihood of death in hospital but lower odds of ICU admission. Pre-terminal PC was associated with lower odds of death in hospital, ICU admission and ALC bed use. DISCUSSION: This study offers new insights into the association between inpatient PC and outcomes at the end of life among Canadians. Future studies could expand on these observations to further understanding of the role of inpatient PC in the end-of-life experience for different populations in Canada.

Epigenetic and transcriptional regulation of IL4-induced CCL17 production in human monocytes and murine macrophages.

Interleukin 4 (IL4) is generally viewed as a Th2 cytokine capable of polarizing macrophages into an anti-inflammatory phenotype, whereas granulocyte macrophage-colony-stimulating factor (GM-CSF) is often viewed as a proinflammatory cytokine with part of this function due to its action on monocytes/macrophages. Paradoxically, these two cytokines act additively to enhance the in vitro differentiation of dendritic cells from precursors such as monocytes. One up-regulated marker of an IL4-polarized M2 macrophage is the chemokine (C-C motif) ligand 17 (CCL17), which we have recently reported to be induced by GM-CSF in monocytes/macrophages in an interferon regulatory factor 4 (IRF4)-dependent manner. In this study, we report that IL4 also induces CCL17 production by acting through IRF4 in human monocytes and murine macrophages. Furthermore, evidence is presented that IL4 up-regulates IRF4 expression at the epigenetic level by enhancing the expression and activity of jumonji domain-containing protein 3 (JMJD3) demethylase. Intriguingly, silencing the signal transducer and activator of transcription 6 (STAT6) gene led to a decrease in not only CCL17 formation, but also in that of its upstream regulators, JMJD3 and IRF4. Moreover, IL4 treatment of human monocytes resulted in an increased association of STAT6 to the promoter regions of the CCL17, IRF4, and JMJD3 genes. Thus, despite their vastly different functions, IL4 and GM-CSF appear to share elements of a common signaling pathway in regulating CCL17 production in human monocytes and murine macrophages.

Rates of emergency department visits attributable to alcohol use in Ontario from 2003 to 2016: a retrospective population-level study.

BACKGROUND: Alcohol use causes a large burden on the health of Canadians, and alcohol-related harms appear to be increasing in many high-income countries. We sought to analyze changes in emergency department visits attributable to alcohol use, by sex, age and neighbourhood income over time. METHODS: All individuals aged 10 to 105 years living in Ontario, Canada, between 2003 and 2016 were included in this study. The primary outcome was age-standardized rates of emergency department visits attributable to alcohol use, defined using diagnostic codes from the Canadian Institute for Health Information Health Indicator "hospitalizations entirely caused by alcohol." We compared rates of these visits using a retrospective population-level design. RESULTS: Among 15 121 639 individuals, there were 765 346 emergency department visits attributable to alcohol use over the study period. Between 2003 and 2016, the age-standardized rates of these visits increased more in women (86.5%) than in men (53.2%), and the increase in rates of emergency department visits attributable to alcohol use was 4.4 times greater than the increases in the rates of overall emergency department visits. Individuals aged 25-29 years experienced the largest change in the rate of emergency department visits attributable to alcohol use (175%). We found evidence of age-cohort effects, whereby the rate of emergency department visits attributable to alcohol use at age 19 years increased on average by 4.07% (95% confidence interval [CI] 3.71%-4.44%) per year for each cohort born between 1986 and 1999. Individuals in the lowest neighbourhood income quintile had 2.37 (95% CI 2.27-2.49) times the rate of emergency department visits attributable to alcohol use than those in the highest income quintile. This disparity increased slightly over the study period. INTERPRETATION: Although men and lower-income individuals have the highest burden of emergency department visits attributable to alcohol use, the largest increases in visits have been in women and younger adults. Further research should focus on potential causes of these trends to provide guidance on how to reduce alcohol-related harms.
