To analyze how structural determinants and barriers within social systems shape options for dying well at home in Canada, while also shaping preferences for dying at home.
Methods
To inform a descriptive thematic analysis, 24 Canadian stakeholders were interviewed about their views, experiences, and preferences about dying at home. Participants included compassionate community advocates, palliative care professionals, volunteers, bereaved family caregivers, residents of rural and remote regions, service providers working with structurally vulnerable populations, and members of francophone, immigrant, and 2SLGBTQ+ communities.
Results
Analysis of stakeholders’ insights and experiences led to the conceptualization of several structural barriers to dying well at home: inaccessible public and community infrastructure and services, a structural gap in death literacy, social stigma and discrimination, and limited access to relational social capital.
Significance of results
Aging in Canada, as elsewhere across the globe, has increased demand for palliative care and support, especially in the home. Support for people wishing to die at home is a key public health issue. However, while Canadian policy documents normalize dying in place as ideal, it is uncertain whether these fit with the real possibilities for people nearing the end of life. Our analysis extends existing research on health equity in palliative and end-of-life care beyond a focus on service provision. Results of this analysis identify the need to expand policymakers’ structural imaginations about what it means to die well at home in Canada.
Cannabis use has been linked to psychotic disorders but this association has been primarily observed in the Global North. This study investigates patterns of cannabis use and associations with psychoses in three Global South (regions within Latin America, Asia, Africa and Oceania) settings.
Methods
Case–control study within the International Programme of Research on Psychotic Disorders (INTREPID) II conducted between May 2018 and September 2020. In each setting, we recruited over 200 individuals with an untreated psychosis and individually-matched controls (Kancheepuram India; Ibadan, Nigeria; northern Trinidad). Controls, with no past or current psychotic disorder, were individually-matched to cases by 5-year age group, sex and neighbourhood. Presence of psychotic disorder assessed using the Schedules for Clinical Assessment in Neuropsychiatry and cannabis exposure measured by the World Health Organisation Alcohol, Smoking and Substance Involvement Screening Test (ASSIST).
Results
Cases reported higher lifetime and frequent cannabis use than controls in each setting. In Trinidad, cannabis use was associated with increased odds of psychotic disorder: lifetime cannabis use (adj. OR 1.58, 95% CI 0.99–2.53); frequent cannabis use (adj. OR 1.99, 95% CI 1.10–3.60); cannabis dependency (as measured by high ASSIST score) (adj. OR 4.70, 95% CI 1.77–12.47), early age of first use (adj. OR 1.83, 95% CI 1.03–3.27). Cannabis use in the other two settings was too rare to examine associations.
Conclusions
In line with previous studies, we found associations between cannabis use and the occurrence and age of onset of psychoses in Trinidad. These findings have implications for strategies for prevention of psychosis.
Extensive evidence indicates that rates of psychotic disorder are elevated in more urban compared with less urban areas, but this evidence largely originates from Northern Europe. It is unclear whether the same association holds globally. This study examined the association between urban residence and rates of psychotic disorder in catchment areas in India (Kancheepuram, Tamil Nadu), Nigeria (Ibadan, Oyo), and Northern Trinidad.
Methods
Comprehensive case detection systems were developed based on extensive pilot work to identify individuals aged 18–64 with previously untreated psychotic disorders residing in each catchment area (May 2018–April/May/July 2020). Area of residence and basic demographic details were collected for eligible cases. We compared rates of psychotic disorder in the more v. less urban administrative areas within each catchment area, based on all cases detected, and repeated these analyses while restricting to recent onset cases (<2 years/<5 years).
Results
We found evidence of higher overall rates of psychosis in more urban areas within the Trinidadian catchment area (IRR: 3.24, 95% CI 2.68–3.91), an inverse association in the Nigerian catchment area (IRR: 0.68, 95% CI 0.51–0.91) and no association in the Indian catchment area (IRR: 1.18, 95% CI 0.93–1.52). When restricting to recent onset cases, we found a modest positive association in the Indian catchment area.
Conclusions
This study suggests that urbanicity is associated with higher rates of psychotic disorder in some but not all contexts outside of Northern Europe. Future studies should test candidate mechanisms that may underlie the associations observed, such as exposure to violence.
There is evidence of an association between life events and psychosis in Europe, North America and Australasia, but few studies have examined this association in the rest of the world.
Aims
To test the association between exposure to life events and psychosis in catchment areas in India, Nigeria, and Trinidad and Tobago.
Method
We conducted a population-based, matched case–control study of 194 participants in India, Nigeria, and Trinidad and Tobago. Cases were recruited through comprehensive population-based, case-finding strategies. The Harvard Trauma Questionnaire was used to measure life events. The Screening Schedule for Psychosis was used to screen for psychotic symptoms. The association between psychosis and having experienced life events (experienced or witnessed) was estimated by conditional logistic regression.
Results
There was no overall evidence of an association between psychosis and having experienced or witnessed life events (adjusted odds ratio 1.19, 95% CI 0.62–2.28). We found evidence of effect modification by site (P = 0.002), with stronger evidence of an association in India (adjusted odds ratio 1.56, 95% CI 1.03–2.34), inconclusive evidence in Nigeria (adjusted odds ratio 1.17, 95% CI 0.95–1.45) and evidence of an inverse association in Trinidad and Tobago (adjusted odds ratio 0.66, 95% CI 0.44–0.97).
Conclusions
This study found no overall evidence of an association between witnessing or experiencing life events and psychotic disorder across three culturally and economically diverse countries. There was preliminary evidence that the association varies between settings.
To identify potential participants for clinical trials, electronic health records (EHRs) are searched at potential sites. As an alternative, we investigated using medical devices used for real-time diagnostic decisions for trial enrollment.
Methods:
To project cohorts for a trial in acute coronary syndromes (ACS), we used electrocardiograph-based algorithms that identify ACS or ST elevation myocardial infarction (STEMI) that prompt clinicians to offer patients trial enrollment. We searched six hospitals’ electrocardiograph systems for electrocardiograms (ECGs) meeting the planned trial’s enrollment criterion: ECGs with STEMI or > 75% probability of ACS by the acute cardiac ischemia time-insensitive predictive instrument (ACI-TIPI). We revised the ACI-TIPI regression to require only data directly from the electrocardiograph, the e-ACI-TIPI using the same data used for the original ACI-TIPI (development set n = 3,453; test set n = 2,315). We also tested both on data from emergency department electrocardiographs from across the US (n = 8,556). We then used ACI-TIPI and e-ACI-TIPI to identify potential cohorts for the ACS trial and compared performance to cohorts from EHR data at the hospitals.
Results:
Receiver-operating characteristic (ROC) curve areas on the test set were excellent, 0.89 for ACI-TIPI and 0.84 for the e-ACI-TIPI, as was calibration. On the national electrocardiographic database, ROC areas were 0.78 and 0.69, respectively, and with very good calibration. When tested for detection of patients with > 75% ACS probability, both electrocardiograph-based methods identified eligible patients well, and better than did EHRs.
Conclusion:
Using data from medical devices such as electrocardiographs may provide accurate projections of available cohorts for clinical trials.
OBJECTIVES/SPECIFIC AIMS: Objective: Approximately 86 million people in the US have prediabetes, but only a fraction of them receive proven effective therapies to prevent diabetes. Further, the effectiveness of these therapies varies with individual risk of progression to diabetes. We estimated the value of targeting those individuals at highest diabetes risk for treatment, compared to treating all individuals meeting inclusion criteria for the Diabetes Prevention Program (DPP). METHODS/STUDY POPULATION: METHODS: Using a micro-simulation model, we estimated total lifetime costs and quality-adjusted life expectancy (QALE) for individuals receiving: (1) lifestyle intervention involving an intensive program focused on healthy diet and exercise, (2) metformin administration, or (3) no intervention. The model combines several components. First a Cox proportional hazards model predicted onset of diabetes from baseline characteristics for each pre-diabetic individual and yielded a probability distribution for each alternative. We derived this risk model from the Diabetes Prevention Program (DPP) clinical trial data and the follow-up study DPP-OS. The Michigan Diabetes Research Center Model for Diabetes then estimated costs and outcomes for individuals after diabetes diagnosis using standard of care diabetes treatment. Based on individual costs and QALE, we evaluated NMB of the two interventions at population and individual levels, stratified by risk quintiles for diabetes onset at 3 years. RESULTS/ANTICIPATED RESULTS: Results: Compared to usual care, lifestyle modification conferred positive benefits for all eligible individuals. Metformin’s NMB was negative for the lowest population risk quintile. By avoiding use among individuals who would not benefit, targeted administration of metformin conferred a benefit of $500-$800 per person, depending on duration of treatment effect. When treating only 20% of the population (e.g., due to capacity constraints), targeting conferred a NMB of $14,000-$18,000 per person for lifestyle modification and $16,000-$20,000 for metformin. DISCUSSION/SIGNIFICANCE OF IMPACT: Conclusions: Metformin confers value only among higher risk individuals, so targeting its use is worthwhile. While lifestyle modification confers value for all eligible individuals, prioritizing the intervention to high risk patients when capacity is constrained substantially increases societal benefits.
The presence of a child afflicted with a life-threatening illness is a difficult situation for the child's siblings, especially when their own needs are left unmet. The present article describes the first three phases of research involved in the conceptualization, development, and content validation of an initial version of the Inventaire des Besoins de la Fratrie d'Enfants Malades Sévèrement (IBesFEMS) [Needs Inventory for Siblings of Critically ill Children].
Method:
The first phase of the development of this instrument was conducted using qualitative methodology (focus groups: 6 siblings, 8 parents). The second phase consisted of validating the content of a pool of items developed according to the needs identified in the first phase. Some 21 participants (3 psychometricians, 3 researchers, 9 clinicians, and 6 siblings) evaluated each item for relevance and clarity. Finally, during the third phase, the acceptability and administration procedures of the preliminary version of the instrument were assessed qualitatively by five siblings.
Results:
The first phase led to production of a typology made up of 43 needs in 10 different environments. The second phase allowed for selection of the items that were clearest and most relevant, based on expert opinion. This procedure gave rise to a first version of the IBesFEMS, which consisted of 48 items.
Significance of results:
The IBesFEMS appears to be a promising tool for specifically assessing the needs of the adolescent siblings of seriously ill children.
Life-threatening illnesses in children have a significant impact on the lives of their brothers and sisters. Consequently, special attention must be paid to the specific needs of these siblings to help them cope with their situations. To address this issue, we developed an inventory of the needs of the adolescent siblings of severely ill children, the Inventaire des Besoins de la Fratrie d'Enfants Malades Sévèrement (IBesFEMS) [Needs Inventory for Siblings of Critically Ill Children]. The present article describes a preliminary validation study of this new instrument.
Method:
In a prospective cohort study, the 48-item instrument was administered via a website or paper to 58 siblings.
Results:
Our study revealed that the measure has an estimated internal consistency of 0.96 and a temporal stability intraclass correlation coefficient (ICC) of 0.86 (p < 0.01). Its convergence validity is also satisfactory.
Significance of results:
Our findings suggest that the IBesFEMS is highly relevant for pediatric palliative care clinicians and researchers. Future studies should investigate its factorial structure and predictive validities.
To provide a richer understanding of food access and purchasing practices among US urban food desert residents and their association with diet and BMI.
Design
Data on food purchasing practices, dietary intake, height and weight from the primary food shopper in randomly selected households (n 1372) were collected. Audits of all neighbourhood food stores (n 24) and the most-frequented stores outside the neighbourhood (n 16) were conducted. Aspects of food access and purchasing practices and relationships among them were examined and tests of their associations with dietary quality and BMI were conducted.
Setting
Two low-income, predominantly African-American neighbourhoods with limited access to healthy food in Pittsburgh, PA, USA.
Subjects
Household food shoppers.
Results
Only one neighbourhood outlet sold fresh produce; nearly all respondents did major food shopping outside the neighbourhood. Although the nearest full-service supermarket was an average of 2·6 km from their home, respondents shopped an average of 6·0 km from home. The average trip was by car, took approximately 2 h for the round trip, and occurred two to four times per month. Respondents spent approximately $US 37 per person per week on food. Those who made longer trips had access to cars, shopped less often and spent less money per person. Those who travelled further when they shopped had higher BMI, but most residents already shopped where healthy foods were available, and physical distance from full-service supermarkets was unrelated to weight or dietary quality.
Conclusions
Improved access to healthy foods is the target of current policies meant to improve health. However, distance to the closest supermarket might not be as important as previously thought, and thus policy and interventions that focus merely on improving access may not be effective.
This extensive survey of migration in the modern world begins in the sixteenth century with the establishment of European colonies overseas, and covers the history of migration to the late twentieth century, when global communications and transport systems stimulated immense and complex flows of labour migrants and skilled professionals. In ninety-five contributions, leading scholars from twenty-seven different countries consider a wide variety of issues including migration patterns, the flights of refugees and illegal migration. Each entry is a substantive essay, supported by up-to-date bibliographies, tables, plates, maps and figures. As the most wide-ranging coverage of migration in a single volume, The Cambridge Survey of World Migration will be an indispensable reference tool for scholars and students in the field.
The purpose of this study was to explore the impact of advanced cancer patients' denial on their family caregivers and how they cope, in order to enable clinicians to better support them and their caregiving.
Method:
As the objective was to obtain clinically useful findings, an interpretive descriptive design was used. Data consisted of prospective semi-structured interviews with 16 family caregivers of advanced cancer patients in denial, field notes, reflexive journals, and memos during the analysis.
Results:
Caregivers experienced extra burdens with the patient's denial. Feeling bound to preserve the denial, which they perceived as immutable, they were prevented from seeking information to manage the patient's care. Additionally, those caring for noncompliant patients felt disenfranchised from their role, resulting in feelings of powerlessness and guilt, and felt burdened by managing medical situations that arose from noncompliance. Caregivers described the ambivalence of feeling frustrated and burdened by the denial while recognizing it as a long-standing coping pattern for the patient. The denial prevented them from acknowledging their own needs to the patients or seeking informal support. They therefore developed solitary coping strategies, sought professional psychosocial support, and/or employed denial themselves.
Significance of results:
Caregivers of patients in denial experience added burdens, which they must bear without most of the usual sources of support. The burden is accentuated when patients are noncompliant with care, placing themselves in dangerous situations. Healthcare providers should identify patients in denial and support their caregivers in meeting both their caregiving and their own needs. Evidence-based strategies to accomplish this should be developed and implemented.
To encourage communication and contribute to the palliative care movement's need for interdisciplinary care, this article offers to explore the stance of volunteers on two fundamental concepts, “health” and “illness,” as well as their related understanding of “palliative care.” Volunteers' understandings are then compared with the concepts put forth by the Canadian Hospice Palliative Care Association (CHPCA) in its “Model to Guide Hospice Palliative Care.”
Method:
Focus groups with volunteers, and individual interviews with coordinators from five selected palliative care community action organizations from across Canada, are used. A total of 65 participants from three Canadian provinces were interviewed.
Results:
Participants view illness as a subjective, multidimensional, and transformative experience that requires multiple adjustments. It is an impediment to personal equilibrium and a challenge for the terminally ill and their close ones. Health, on the other hand, is a complex phenomenon that consists of physical, psychological, social, and spiritual well-being. For participants, health is most often embodied by a person's capacity to adjust to their challenging circumstances. Both volunteers and coordinators see palliative care as an alternative approach to care that centers on helping patients and their families through their ordeal by offering comfort and respite, and helping patients enjoy their life for as long as possible.
Significance of Results:
Participants describe illness as a destabilizing loss and palliative care as a means to compensate for the numerous consequences this loss brings; their actions reflect these principles and are compatible with the CHPCA model.
We have chosen the name of GYES, one of the mythological giants with one hundred arms,offspring of Gaia and Uranus, for our instrument study of a multifibre spectrograph forthe prime focus of the Canada-France-Hawaii Telescope. Such an instrument could provide anexcellent ground-based complement for the Gaia mission and a northern complement to theHERMES project on the AAT. The CFHT is well known for providing a stable prime focusenvironment, with a large field of view, which has hosted several imaging instruments, buthas never hosted a multifibre spectrograph. Building upon the experience gained at GÉPIwith FLAMES-Giraffe and X-Shooter, we are investigating the feasibility of a highmultiplex spectrograph (about 500 fibres) over a field of view one degree in diameter. Weare investigating an instrument with resolution in the range 15 000 to 30 000, whichshould provide accurate chemical abundances for stars down to 16th magnitude and radialvelocities, accurate to 1 km s-1 for fainter stars. The study is led byGÉPI-Observatoire de Paris with a contribution from Oxford for the study of thepositioner. The financing for the study comes from INSU CSAA and Observatoire de Paris.The conceptual study will be delivered to CFHT for review by October 1st 2010.
When a family member is faced with a terminal illness, the impending death presents a crisis and a challenge to the entire family as a system. This article highlights the importance of caring for a family when one member has a life-threatening illness, and describes the applicability of Family Systems Theory and its major tenets to the palliative cancer population.
Methods:
A MedLine and CINAHL search of Family Systems Theory related papers was conducted.
Results:
Research studies that have been done fail to capture the view of the entire family system, often limiting the perspectives of the family to one single member. The concepts of holism, balance, boundaries, and hierarchal subsystems must be addressed in the care of any family, including those who have a family member who is dying.
Significance of results:
A Family Systems Theory framework can be useful in helping health care providers, and particularly nurses, deliver optimal care to palliative cancer patients and their families and standardize the way research is done by providing an appropriate framework with which to study the family. In addition, the adoption of Family Systems Theory as the standard framework from which to study families in palliative care will provide consistency for future studies that is presently lacking. Finally, nursing interventions to care for the family are suggested based on Family Systems Theory.
