Palliative care integration into outpatient heart failure management: pilot study.

OBJECTIVES: People with heart failure have palliative care needs yet services remain underused. The heart failure clinic is a potential setting for initial palliative care delivery though evidence for such services is lacking. We explored the outcomes of an embedded model of palliative medicine within a heart failure clinic. METHODS: We conducted a retrospective cohort study of individuals who received a palliative medicine consultation in a heart failure clinic. Descriptive statistics were used to characterise the cohort and their outcomes, and the McNemar test to compare rates of advance care planning before/after consultation. RESULTS: Majority of individuals who received a palliative medicine consultation experienced New York Heart Association (NYHA) class II symptoms (65.5%) and had a Palliative Performance Scale score of≥60% (66.8%). While only 17% engaged in advance care planning in the year before consultation, 93% had advance care planning during the first consultation (p<0.001). Care was provided in multiple domains including advance care planning (95%), symptom management (97%) and caregiver support (30%), regardless of the reason for referral. CONCLUSIONS: Our embedded model of palliative medicine within the heart failure clinic was associated with increased advance care planning at a time when patients were functional and minimally symptomatic. Further research should substantiate these findings at other sites.

Start of the COVID-19 Pandemic and Palliative Care Unit Utilization: A Retrospective Cohort Study.

CONTEXT: People with noncancer diagnoses have poorer access to palliative care units (PCUs) or hospices compared to those with cancer diagnoses. The COVID-19 pandemic disrupted how specialist palliative care services were delivered and utilized. OBJECTIVE: To determine the association between the start of the COVID-19 pandemic and PCU/hospice utilization in hospitalized individuals with cancer and noncancer diagnoses with specialist palliative care needs. METHODS: Retrospective cohort study using routinely collected data. Percentages of individuals experiencing each disposition from hospital, including discharge to PCU/hospice, were calculated monthly for the total, cancer, and noncancer cohorts and were analyzed descriptively. Hospitalized individuals with specialist palliative care needs at a single academic hospital in Toronto, Canada from January 1, 2017, to September 31, 2022 (pandemic start was defined as April 1, 2020). RESULTS: The cohort comprised 4349 individuals (median age=78 years; 52.4% female); 3065 (70.5%) and 1284 (29.5%) had cancer and noncancer diagnoses, respectively. Among individuals with noncancer diagnoses, the most significant absolute changes were a 13.0%-decrease in in-hospital deaths (prepandemic=49.6%; postpandemic=36.6%) and a 11.6%-increase in discharges to PCU/hospice (prepandemic=35.6%; postpandemic=47.3%). Among individuals with cancer, the most significant absolute changes were a 12.8%-increase in discharges home with formal care (prepandemic=2.3%; postpandemic=15.1%) and a 7.0%-decrease in in-hospital deaths (prepandemic=29.1%; postpandemic=22.0%). CONCLUSION: Despite historically poor PCU/hospice access, the COVID-19 pandemic created circumstances that may have enabled unprecedented utilization in individuals with noncancer diagnoses in our cohort.

Study protocol for the development and validation of a clinical prediction tool to estimate the risk of 1-year mortality among hospitalized patients with dementia.

BACKGROUND: Patients with dementia and their caregivers could benefit from advance care planning though may not be having these discussions in a timely manner or at all. A prognostic tool could serve as a prompt to healthcare providers to initiate advance care planning among patients and their caregivers, which could increase the receipt of care that is concordant with their goals. Existing prognostic tools have limitations. We seek to develop and validate a clinical prediction tool to estimate the risk of 1-year mortality among hospitalized patients with dementia. METHODS: The derivation cohort will include approximately 235,000 patients with dementia, who were admitted to hospital in Ontario from April 1st, 2009, to December 31st, 2017. Predictor variables will be fully prespecified based on a literature review of etiological studies and existing prognostic tools, and on subject-matter expertise; they will be categorized as follows: sociodemographic factors, comorbidities, previous interventions, functional status, nutritional status, admission information, previous health care utilization. Data-driven selection of predictors will be avoided. Continuous predictors will be modelled as restricted cubic splines. The outcome variable will be mortality within 1 year of admission, which will be modelled as a binary variable, such that a logistic regression model will be estimated. Predictor and outcome variables will be derived from linked population-level healthcare administrative databases. The validation cohort will comprise about 63,000 dementia patients, who were admitted to hospital in Ontario from January 1st, 2018, to March 31st, 2019. Model performance, measured by predictive accuracy, discrimination, and calibration, will be assessed using internal (temporal) validation. Calibration will be evaluated in the total validation cohort and in subgroups of importance to clinicians and policymakers. The final model will be based on the full cohort. DISCUSSION: We seek to develop and validate a clinical prediction tool to estimate the risk of 1-year mortality among hospitalized patients with dementia. The model would be integrated into the electronic medical records of hospitals to automatically output 1-year mortality risk upon hospitalization. The tool could serve as a trigger for advance care planning and inform access to specialist palliative care services with prognosis-based eligibility criteria. Before implementation, the tool will require external validation and study of its potential impact on clinical decision-making and patient outcomes. TRIAL REGISTRATION: NCT05371782.

Differences in trends in discharge location in a cohort of hospitalized patients with cancer and non-cancer diagnoses receiving specialist palliative care: A retrospective cohort study.

BACKGROUND: Patients with and without cancer are frequently hospitalized, and have specialist palliative care needs. In-hospital mortality can serve as a quality indicator of acute care. Trends in acute care outcomes have not previously been evaluated in patients with confirmed specialist palliative care needs or between diagnostic groups. AIM: To compare trends in discharge location between hospitalized patients with and without cancer who received specialist palliative care. DESIGN: Retrospective cohort study. Association between diagnosis (cancer, non-cancer) and in-hospital mortality was assessed using multivariable logistic regression, controlling for demographic, clinical, and admission-specific information. SETTING/PARTICIPANTS: Patients who received specialist palliative care at an academic tertiary hospital in Toronto, Canada from 2013 to 2019. RESULTS: The cohort comprised 6846 patients, 5024 with and 1822 without cancer. A higher proportion of patients without cancer had a Palliative Performance Scale score <30%, anticipated prognosis of <1 month, and were referred for end-of-life care (all p < 0.001). The adjusted odds of dying in hospital was 1.24-times higher among patients without cancer (95% CI: 1.05-1.46; p = 0.011). Though the proportion of patients without cancer who died in hospital decreased by 8.4% from 2013 to 2019, this proportion (41.2%) remained substantially higher compared to patients with cancer (14.0%) in 2019. CONCLUSIONS: Hospitalized patients without cancer were referred to specialist palliative care at a lower functional status, a poorer anticipated prognosis, and more likely for end-of-life care; and were more likely to die in hospital. Future studies are required to determine whether a proportion of hospital deaths in patients without cancer represent goal-discordant end-of-life care.

Specialist Palliative Care Referral Practices Among Oncologists, Cardiologists, Respirologists: A Comparison of National Survey Studies.

CONTEXT: Although patients with nonmalignant diseases have palliative care needs similar to those of cancer patients, they are less likely to receive specialist palliative care (SPC). Referral practices of oncologists, cardiologists, and respirologists could provide insight into reasons for this difference. OBJECTIVES: We compared referral practices to SPC among cardiologists, respirologists, and oncologists, discerned from surveys (the Canadian Palliative Cardiology/Respirology/Oncology Surveys). METHODS: Descriptive comparison of survey studies; multivariable linear regression analysis of association between specialty and referral frequency. Surveys for each specialty were disseminated to physicians across Canada in 2010 (oncologists) and 2018 (cardiologists, respirologists). RESULTS: The combined response rate of the surveys was 60.9% (1568/2574): 603 oncologists, 534 cardiologists, and 431 respirologists. Perceived availability of SPC services was higher for cancer than for noncancer patients. Oncologists were more likely to make a referral to SPC for a symptomatic patient with a prognosis of

Pediatric and Adult Cardiologists' and Respirologists' Referral Practices to Palliative Care.

CONTEXT: Children and adults with advanced cardiac or respiratory disease may benefit from specialized palliative care (SPC), but there has been little SPC research in this area. OBJECTIVES: To explore pediatric cardiologists' and respirologists' (pediatric clinicians) beliefs about and referral practices to SPC and compare these results to adult cardiologists and respirologists (adult clinicians). METHODS: Pediatric and adult clinicians were sent a survey exploring SPC referral practices and beliefs. Responses were summarized with descriptive statistics. Pediatric and adult clinicians' responses were compared using Pearson's chi-square test. RESULTS: The response rate was 56% (989/1759); 9% (87/989) were pediatric clinicians. Pediatric clinicians were more likely than adult clinicians to be female, work in an academic center, and experience fewer patient deaths (P<0.001). Pediatric clinicians reported better access to SPC clinical nurse specialists, spiritual care specialists and bereavement counselors (P<0.001), while adult clinicians reported better access to palliative care units (P<0.001). Pediatric clinicians referred to SPC earlier, while adult clinicians tended to refer after disease directed therapies were stopped (P<0.001). More than half of all clinicians felt patients had negative perceptions of the phrase "palliative care". Although most clinicians were satisfied with SPC quality (73-82%), fewer adult clinicians were satisfied with SPC availability (74 vs. 47%; P<0.001). Fewer pediatric clinicians felt that SPC prioritized oncology patients (13 vs. 53%; P<0.001). CONCLUSION: There are important differences between pediatric and adult clinicians' beliefs about and referral practices to SPC. This may reflect unique features of pediatric diseases, provider characteristics, care philosophies, or service availability.

Race and birth country are associated with discharge location from hospital: A retrospective cohort study of demographic differences for patients receiving inpatient palliative care.

BACKGROUND: While past studies investigated access to palliative care among marginalized groups, few assessed whether there are differences in clinical process indicators based on demographics among those receiving palliative care. We aimed to: describe demographics among patients receiving inpatient palliative care; and evaluate whether demographic variables are associated with differences in disposition (i.e., discharge location), length of stay (LOS), and timing of inpatient palliative care referral and consultation. METHODS: Retrospective cohort study using electronic medical record data to study patients seen by inpatient palliative care at Mount Sinai Hospital in Toronto, Canada between April 2018 to March 2019. Primary outcome was disposition. Secondary outcomes were LOS, time from admission to palliative referral, and time from referral to consultation. We summarized quantitative data descriptively and used fisher exact tests to explore relationships between categorial variables. For continuous outcomes, we ran one-way ANOVA tests. FINDINGS: A total of 187 patients were referred to palliative care and met inclusion criteria. Mean age was 68·8 and 55·6% were female. 46·7% were born in Canada, 58·2% were White and 78·4% preferred English communication. Variables significantly associated with disposition were: birth country (p = 0·04), and race/ethnicity (p = 0·03). Language (F ratio = 3·6, p = 0·004) was significantly associated with time from admission to palliative care referral. No variables were associated with LOS or time from referral to consult. INTERPRETATION: Inequalities in disposition, and how long it takes to refer to palliative care may exist. Further studies should focus on understanding the underlying practices that constructed, and maintained these inequalities in care. FUNDING: This research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors.

Pulmonary referrals to specialist palliative medicine: a survey.

OBJECTIVES: Patients with chronic respiratory disease have significant palliative care needs, but low utilisation of specialist palliative care (SPC) services. Decreased access to SPC results in unmet palliative care needs among this patient population. We sought to determine the referral practices to SPC among respirologists in Canada. METHODS: Respirologists across Canada were invited to participate in a survey about their referral practices to SPC. Associations between referral practices and demographic, professional and attitudinal factors were analysed using regression analyses. RESULTS: The response rate was 64.7% (438/677). Fifty-nine per cent of respondents believed that their patients have negative perceptions of palliative care and 39% were more likely to refer to SPC earlier if it was renamed supportive care. While only 2.7% never referred to SPC, referral was late in 52.6% of referring physicians. Lower frequency of referral was associated with equating palliative care to end-of-life care (p<0.001), male sex of respirologist (p=0.019), not knowing referral criteria of SPC services (p=0.015) and agreement that SPC services prioritise patients with cancer (p=0.025); higher referral frequency was associated with satisfaction with SPC services (p=0.001). Late referral was associated with equating palliative care to end-of-life care (p<0.001) and agreement that SPC services prioritise patients with cancer (p=0.013). CONCLUSIONS: Possible barriers to respirologists' timely SPC referral include misperceptions about palliative care, lack of awareness of referral criteria and the belief that SPC services prioritise patients with cancer. Future studies should confirm these barriers and evaluate the effectiveness of strategies to overcome them.

Referral Practices of Cardiologists to Specialist Palliative Care in Canada.

BACKGROUND: Patients with heart failure have palliative care needs that can be effectively addressed by specialist palliative care (SPC). Despite this, SPC utilization by this patient population is low, suggesting barriers to SPC referral. We sought to determine the referral practices of cardiologists to SPC. METHODS: Cardiologists across Canada were invited to participate in a survey about their referral practices to SPC. Associations between referral practices and demographic, professional, and attitudinal factors were analyzed using multiple and logistic regression. RESULTS: The response rate was 51% (551 of 1082). Between 35.1% and 64.2% of respondents were unaware of referral criteria to local SPC services. Of the respondents, 29% delayed SPC referral because of prognostic uncertainty, and 46.8% believed that SPC prioritizes patients with cancer. In actual practice, nearly three-fourths of cardiologists referred late. Referral frequency was associated with greater availability of SPC services for patients with nonmalignant diseases (P = 0.008), a higher number of palliative care settings accepting patients receiving continuous infusions or pursuing acute care management (P < 0.001), satisfaction with services (P < 0.001), and less equation of palliative care with end-of-life care (P < 0.001). Early timing of referral was associated with greater availability of SPC services for patients with nonmalignant diseases and less equation of palliative care with end-of-life care. CONCLUSIONS: The findings suggest that barriers to timely SPC referral include an insufficiency of services for patients with nonmalignant diseases especially in the outpatient setting, the perception that SPC services do not accept patients receiving cardiology-specific treatments, and a misperception about the identity of palliative care.

CONTEXTE: Les services de soins palliatifs spécialisés (SPS) peuvent répondre efficacement aux besoins des patients présentant une insuffisance cardiaque. Malgré tout, les patients de cette population n'ont pas beaucoup recours aux SPS, ce qui semble indiquer la présence d'obstacles à l'orientation vers les SPS. Nous avons entrepris de déterminer les pratiques des cardiologues en matière d'orientation des patients vers les SPS. MÉTHODOLOGIE: Les cardiologues de partout au Canada ont été invités à participer à un sondage sur leurs pratiques en matière d'orientation des patients vers les SPS. Les associations entre ces pratiques et certaines caractéristiques démographiques, professionnelles et comportementales ont été analysées au moyen d'une régression multiple et logistique. RÉSULTATS: Le taux de participation au sondage a été de 51 % (551 réponses sur 1 082 invitations). Entre 35,1 et 64,2 % des répondants ne connaissaient pas les critères pour l'orientation des patients vers les services locaux de SPS. Parmi les répondants, 29 % ont dit reporter l'orientation vers les SPS en raison du caractère incertain du pronostic, et 46,8 % croyaient que les SPS s'adressaient en priorité aux patients atteints d'un cancer. Dans la pratique, près des trois quarts des cardiologues ont orienté tardivement les patients. La fréquence des orientations a été associée à une disponibilité plus grande de services de SPS pour les patients atteints de maladies non cancéreuses (p = 0,008), à un nombre plus élevé de milieux de soins palliatifs admettant les patients nécessitant des perfusions continues ou prenant en charge les soins actifs (p < 0,001), à la satisfaction à l'égard des services (p < 0,001) et à une assimilation moins importante des soins palliatifs avec les soins de fin de vie (p < 0,001). L'orientation rapide des patients était associée à une disponibilité plus grande de services de SPS pour les patients atteints de maladies non cancéreuses et à une assimilation moins importante des soins palliatifs avec les soins de fin de vie. CONCLUSIONS: Nos observations semblent indiquer que l'insuffisance des services destinés aux patients atteints de maladies non cancéreuses (en particulier dans le contexte des soins ambulatoires), la perception que les services de SPS n'admettent pas les patients nécessitant des traitements en cardiologie et la perception erronée de la finalité des soins palliatifs constituent des obstacles à l'orientation des patients vers les SPS en temps opportun.

Presence of urinary symptoms in bacteremic urinary tract infection: a retrospective cohort study of Escherichia coli bacteremia.

BACKGROUND: It is important to understand clinical features of bacteremic urinary tract infection (bUTI), because bUTI is a serious infection that requires prompt diagnosis and antibiotic therapy. Escherichia coli is the most common and important uropathogen. The objective of our study was to characterize the clinical presentation of E coli bUTI. METHODS: Retrospective cohort study of consecutive adult patients admitted for community acquired E. coli bacteremia from January 1, 2015 to December 31, 2016 was conducted at 4 acute care academic and community hospitals in Toronto, Ontario, Canada. Logistic regression models were developed to identify E coli bUTI cases without urinary symptoms. RESULTS: Of 462 patients with E. coli bacteremia, 284 (61.5%) patients had a urinary source. Of these 284 patients, 161 (56.7%) had urinary symptoms. In a multivariable model, bUTI without urinary symptoms were associated with older age (age < 65 years as reference, age 65-74 years had OR of 2.13 95% CI 0.99-4.59 p = 0.0523; age 75-84 years had OR of 1.80 95% CI 0.91-3.57 p = 0.0914; age > =85 years had OR of 2.95 95% CI 1.44-6.18 p = 0.0036) and delirium (OR of 2.12 95% CI 1.13-4.03 p = 0.0207). Sepsis by SIRS criteria was present in 274 (96.5%) of all bUTI cases and 119 (96.8%) of bUTI cases without urinary symptoms. CONCLUSION: The majority of patients with E. coli bacteremia had a urinary source. A significant proportion of bUTI cases had no urinary symptoms elicited on history. Elderly and delirious patients were more likely to have bUTI without urinary symptoms. In elderly and delirious patients with sepsis by SIRS criteria but without a clear infectious source, clinicians should suspect, investigate, and treat for bUTI.

Association between Chinese or South Asian ethnicity and end-of-life care in Ontario, Canada.

BACKGROUND: Ethnicity may be associated with important aspects of end-of-life care, such as what treatments are received, access to palliative care and where people die. However, most studies have focused on end-of-life care of white, Hispanic and black patients. We sought to compare end-of-life care delivered to people of Chinese and South Asian ethnicity with that delivered to others from the general population, in Ontario, Canada. METHODS: In this population-based cohort study, we included all people who died in Ontario, Canada, between Apr. 1, 2004, and Mar. 31, 2015. People were identified as having Chinese or South Asian ethnicity on the basis of a validated surname algorithm. We used modified Poisson regression analyses to assess location of death and care received in the last 6 months of life. RESULTS: We analyzed 967 339 decedents, including 18 959 (2.0%) of Chinese and 11 406 (1.2%) of South Asian ethnicity. Chinese (13.6%) and South Asian (18.5%) decedents were more likely than decedents from the general population (10.1%) to die in the intensive care unit (ICU). The adjusted relative risk of dying in intensive care was 1.21 (95% confidence interval [CI] 1.15 to 1.27) for Chinese and 1.25 (95% CI 1.20 to 1.30) for South Asian decedents. In their last 6 months of life, decedents of Chinese and South Asian ethnicity experienced significantly more ICU admission, hospital admission, mechanical ventilation, dialysis, percutaneous feeding tube placement, tracheostomy and cardiopulmonary resuscitation than the general population. INTERPRETATION: Decedents of Chinese and South Asian ethnicity in Ontario were more likely than decedents from the general population to receive aggressive care and to die in an ICU. These findings may be due to communication difficulties between patients and clinicians, differences in preferences about end-of-life care or differences in access to palliative care services.

Salmonella Thompson splenic abscess in a healthy female.

A 26-year-old woman presented with a 5-day history of fever and 3-day history of left upper quadrant abdominal pain and cough associated with left shoulder tip pain. Initial blood cultures did not display growth. On CT imaging, there was a cyst measuring 7.2×8 cm originally interpreted to be haemorrhagic in nature. Repeat cultures during admission revealed Salmonella Thompson. Percutaneous drainage and antibiotic treatment, rather than splenectomy, was successfully pursued with the patient afebrile and in no pain at 6 weeks follow-up.

Prosthetic vascular graft infection and prosthetic joint infection caused by Pseudomonas stutzeri.

Pseudomonas stutzeri is infrequently isolated from clinical specimens, and if isolated, more likely represents colonization or contamination rather than infection. Despite this, there are dozens of case reports which describe clinically significant P. stutzeri infections at variable sites. A 69-year-old man had a P. stutzeri infection of a prosthetic vascular graft infection, which he received in Panama City. He was successfully treated with a single antipseudomonal agent for 6 weeks and the removal of the infected vascular graft. A 70-year-old man had a P. stutzeri infection of a prosthetic joint, which was successfully treated with a single anti-pseudomonal agent for 6 weeks. There is only one other documented case of a prosthetic vascular graft infection secondary to P. stutzeri. There are 5 documented cases of P. stutzeri prosthetic joint infections. The previous cases were treated with antibiotics and variably, source control with the removal of prosthetic material. Most cases of P. stutzeri infection are due to exposure in health care settings. Immunocompromised states such as HIV or hematological and solid tumor malignancies are risk factors for P. stutzeri infection. Infections caused by P. stutzeri are far less frequent and less fatal than those caused by P. aeruginosa. The etiology of a P. stutzeri infection could be exposure to soil and water, but also contaminated material in the health care setting or an immunocompromised state. Iatrogenic infections that are secondary to health care tourism are a potential cause of fever in the returned traveler.

Unruptured intracranial aneurysm treatment effects on cognitive function: a meta-analysis.

OBJECTIVE: The treatment of an unruptured intracranial aneurysm (UIA) is not free of morbidity and mortality, and the decision is made by weighing the risks of treatment complications against the risk of aneurysm rupture. This meta-analysis quantitatively analyzed the literature on the effects of UIA treatment on cognition. METHODS: MEDLINE, Embase, and PsycInfo were systematically searched for studies that reported on the cognitive status of UIA patients before and after aneurysm treatment. The search was restricted to prospective cohort and case-control studies published between January 1, 1998, and January 1, 2013. The analyses focused on the effect of treatment on general cognitive functioning, with an emphasis on 4 specific cognitive domains: executive functions, verbal and visual memory, and visuospatial functions. RESULTS: Eight studies, with a total of 281 patients, were included in the meta-analysis. Treatment did not affect general cognitive functioning (effect size [ES] -0.22 [95% CI -0.78 to 0.34]). Executive functions and verbal memory domains trended toward posttreatment impairment (ES -0.46 [95% CI -0.93 to 0.01] and ES -0.31 [95% CI -1.24 to 0.61]), and performance of visual memory tasks trended toward posttreatment improvement (ES 1.48 [95% CI -0.36 to 3.31]). Lastly, treatment did not significantly affect visuospatial functions (ES -0.08 [95% CI -0.30 to 0.45]). CONCLUSIONS: The treatment of an UIA does not seem to affect long-term cognitive function. However, definitive conclusions were not possible due to the paucity of studies addressing this issue.

Behavioral profile of unruptured intracranial aneurysms: a systematic review.

OBJECTIVES: To systematically review the literature on the neuropsychological, psychosocial, and functional profiles of patients with unruptured intracranial aneurysms. METHODS: This review was limited to peer-reviewed research articles that reported cognitive, psychosocial, and/or functional profiles of patients with unruptured intracranial aneurysms. Studies were identified through Medline and PsychINFO by searching "(unruptured [intracranial OR cerebral] aneurysm) AND (cogniti* OR neuropsycholog* OR anxiety OR depression OR [quality of life] OR work OR employment OR [activities of daily living] OR [instrumental activities of daily living])." Only articles that were published since January 1997 were considered. Reference lists of included articles were inspected for additional studies. Only articles in English were included. Case studies were excluded. Twenty-two articles were included in this review. RESULTS: The literature demonstrates that although treatment for unruptured intracranial aneurysms allays anxiety, it also results in an observable, though transient decline in cognition and daily functioning. Even before treatment, preliminary evidence hints that these patients are not free of such impairments. CONCLUSIONS: The algorithm that underlies the decision to treat an unruptured intracranial aneurysm ought to add more weight to the neuropsychological, psychosocial, and functional profiles of these patients. The clinical relevance of these patients does not begin and end with their risk of rupture.
