Introduction: Patients with transplant-ineligible (TIE) multiple myeloma (MM) have high rates of symptom burden. The aim of this study was to develop and validate a prognostic model to predict symptoms in patients with TIE MM.

Methods: In this population-based, retrospective cohort study, using multiple administrative health care databases linked using a unique encrypted patient identifier in Ontario, Canada, symptoms were identified using the patient self-reported Edmonton Symptom Assessment System (ESAS) at each clinic visit.

Article Synopsis
  • A survival prognostication model was developed for pancreatic ductal adenocarcinoma (PDAC) patients using clinical data, patient-reported symptoms, and treatment specifics to aid in their treatment decisions.
  • The study analyzed data from 17,450 PDAC patients in Ontario over a 13-year period, finding significant predictors of survival, including tumor location, disease stage, hospitalizations, heart failure, and various pain and performance scores.
  • The model demonstrated good predictive accuracy with a C index of 0.76, suggesting it could enhance shared decision-making between patients and healthcare providers regarding treatment options.

Importance: Despite research supporting the benefits of early palliative care, timely initiation by gynecologic oncology patients is reportedly low, which may limit the effectiveness of palliative care.

Objective: To investigate the association of the timing of palliative care initiation with the aggressiveness of end-of-life care using established quality indicators among patients with ovarian cancer.

Design, Setting, And Participants: This population-based retrospective cohort study of ovarian cancer decedents used linked administrative health care data to identify palliative care provision across all health care sectors and health care professionals (specialist and nonspecialist) and end-of-life quality indicators in Ontario, Canada, from 2006 to 2018.

Interprofessional collaboration in palliative care is essential to ensuring high-quality care for seriously ill patients. Education interventions to increase competency in palliative care should incorporate team-building skills to encourage an interprofessional approach. We developed and piloted a virtual educational program named CAPACITI for interprofessional teams to promote a community palliative approach to care.

Purpose: Many cancer survivors have ongoing follow-up with their oncologist(s), despite evidence that this care can be competently managed by primary care and transitioning well survivors could relieve growing pressure on cancer care systems. We analyzed population-based administrative data from Ontario, Canada, to examine rates of transition to primary care-led follow-up care during the survivorship phase, including clinical and demographic predictors associated with being transitioned.

Methods: We conducted a retrospective cohort study to describe the patterns of survivorship follow-up care among all patients with breast cancer in Ontario from 2006 to 2016.

Objectives: To describe the rate, timing, and pattern of changes in advance directives (ADs) of do not resuscitate (DNR) and do not hospitalize (DNH) orders among new admissions to nursing homes (NHs).

Design: A retrospective cohort study.

Setting And Participants: Admissions to all publicly funded NHs in Ontario, Canada, between January 1, 2013, and December 31, 2017.

Developing prognostic tools specifically for patients themselves represents an important step in empowering patients to engage in shared decision-making. Incorporating patient-reported outcomes may improve the accuracy of these prognostic tools. We conducted a retrospective population-based study of transplant-ineligible (TIE) patients with multiple myeloma (MM) diagnosed between January 2007 and December 2018.

Indices of aggressive or supportive end-of-life (EOL) care are used to evaluate health services quality. Disparities according to sex were previously described, with studies showing that male sex is associated with aggressive EOL care. This is a secondary analysis of 69,983 patients who died of a GI malignancy in Ontario between 2006 and 2018.

Purpose: This study aims to describe the treatment patterns, outcomes, health care utilization and symptom burden of triple class exposed (TCE) relapsed/refractory patents with multiple myeloma (MM) receiving a subsequent line of treatment (LOT).

Methods: This is a retrospective observational cohort study using administrative databases in Ontario, Canada. Outcomes were captured for TCE patients receiving a subsequent LOT and included: treatment regimen details, time to next treatment (TTNT), overall survival (OS), health care utilization, palliative care referral, and patient reported symptoms.

Background: Primary- and specialist-level palliative care services are needed. They should work collaboratively and synergistically. Although several service models have been described, these remain open to different interpretations and deployment.

Article Synopsis
  • - The COVID-19 pandemic significantly impacted cancer care delivery, particularly concerning where patients died and the availability of specialized palliative care (SPC).
  • - A study analyzed data from Ontario’s Cancer Registry to assess the association between the pandemic and home deaths or SPC delivery, focusing on socioeconomic disparities.
  • - Findings showed that while home deaths increased during the pandemic, this rise was less pronounced among the most deprived socioeconomic group, revealing potential disparities in end-of-life care access.

Background: CAPACITI is a virtual education program that teaches primary care teams how to provide an early palliative approach to care. After piloting its implementation, we conducted an in-depth qualitative study with CAPACITI participants to assess the effectiveness of the components and to understand the challenges and enablers to virtual palliative care education.

Methods: We applied a qualitative case study approach to assess and synthesize three sources of data collected from the teams that participated in CAPACITI: reflection survey data, open text survey data, and focus group transcriptions.

Background: Children with life-threatening conditions frequently experience high intensity care at the end of life, though most of this research only focused on children with cancer. Some research suggests inequities in care provided based on age, disease type, socioeconomic status, and distance that the child lives from a tertiary hospital. We examined: 1) the prevalence of indicators of high intensity end-of-life care (e.

Objectives: Because of an increasing need to build capacity for end-of-life care, improving access to palliative care is a priority. Where a physician practices (eg, hospital, outpatient clinic, home) directly relates to the type of service and the stage of illness at which care is provided. In this study, we describe the physician palliative care specialist workforce and the settings of care within which they practice.

Survival has improved in patients diagnosed with multiple myeloma (MM) over the last two decades; however, there remains a paucity of data on the causes of death in MM patients and whether causes of death change during the disease trajectory. We conducted a retrospective population-based study to evaluate the rates of MM-specific versus non-MM cause of death and to identify factors associated with cause-specific death in MM patients, stratified into autologous stem cell transplant (ASCT) and non-ASCT cohorts. A total of 6,677 patients were included, 2,576 in the ASCT group and 4,010 in the non-ASCT group.

Background: Several clinician training interventions have been developed in the past decade to address serious illness communication. While numerous studies report on clinician attitudes and confidence, little is reported on individual education modalities and their impact on actual behavior change and patient outcomes.

Aim: To examine what is known about the education modalities used in serious illness communication training and their impact on clinician behaviors and patient outcomes.

Objective: Early palliative care (PC) is associated with improved patient quality of life, less aggressive end-of-life care, and prolonged survival. We evaluated patterns of PC delivery in gynecologic oncology.

Methods: We conducted a population-based, retrospective cohort study of gynecologic cancer decedents in Ontario from 2006 to 2018 using linked administrative health care data.
