Increasing Prevalence and Stable Incidence Rates of Inflammatory Bowel Disease Among First Nations: Population-Based Evidence From a Western Canadian Province

BACKGROUND

There is limited to no evidence of the prevalence and incidence rates of inflammatory bowel disease (IBD) among Indigenous peoples. In partnership with Indigenous patients and family advocates, we aimed to estimate the prevalence, incidence, and trends over time of IBD among First Nations (FNs) since 1999 in the Western Canadian province of Saskatchewan.

METHODS

We conducted a retrospective population-based study linking provincial administrative health data from the 1999-2000 to 2016-2017 fiscal years. An IBD case definition requiring multiple health care contacts was used. The prevalence and incidence data were modeled using generalized linear models and a negative binomial distribution. Models considered the effect of age groups, sex, diagnosis type (ulcerative colitis [UC], Crohn disease [CD]), and fiscal years to estimate prevalence and incidence rates and trends over time.

RESULTS

The prevalence of IBD among FNs increased from 64/100,000 (95% confidence interval [CI], 62-66) in 1999-2000 to 142/100,000 (95% CI, 140-144) people in 2016-2017, with an annual average increase of 4.2% (95% CI, 3.2%-5.2%). Similarly, the prevalence of UC and CD, respectively, increased by 3.4% (95% CI, 2.3%-4.6%) and 4.1% (95% CI, 3.3%-4.9%) per year. In contrast, the incidence rates of IBD, UC, and CD among FNs depicted stable trends over time; no statistically significant changes were observed in the annual change trend tests. The ratio of UC to CD was 1.71.

CONCLUSIONS

We provided population-based evidence of the increasing prevalence and stable incidence rates of IBD among FNs. Further studies are needed in other regions to continue understanding the patterns of IBD among Indigenous peoples.

Evolution of a community-centred experiential learning module: A mixed-methods approach to promote social accountability and community partnership in undergraduate medical education

This article was migrated. The article was marked as recommended. Background: Education in social determinants of health (SDH) has become an important part of medical curricula, facilitated increasingly through students' experiential learning with communities. The Community and Workplace Centred Learning Experience (CWCLE) module of the University of Saskatchewan, Canada, intends to integrate and extend second-year medical students' attitudes, skills, and knowledge about SDH and community resources. We aimed to: 1) Solicit students' self-evaluation of their ability to perform module learning objectives, 2) Assess module impact on student attitudes toward SDH, 3) Obtain feedback from community partners and students about their community experiences, and 4) Use feedback to collaboratively develop recommendations to enhance the CWCLE module. Methods: We used a mixed-method approach to combine quantitative data with stories and personal experiences. We developed an online survey for two cohorts of students who had completed the module, soliciting students to self-evaluate their perceived abilities to perform the module's learning objectives and evaluating students' attitudes towards SDH. We invited representatives from community agencies involved in the CWCLE module to participate in focus groups. We also held separate focus groups with students who participated in the online survey to elaborate on their survey comments. Results: In total, 145 students participated in the online survey (response rate=72.5%). Eleven community agency representatives and seven students participated in five focus groups. Our results demonstrate that medical students benefit from community-based experiential learning of SDH and community resources. We trace evaluations and discussions in the ongoing development of this community-based experiential learning module from its initial, primarily medical-school driven designs, towards a substantial involvement of community-based organizations in its operation and continuing redevelopment. Conclusions: Our mixed method offered us a better understanding of module impact and opportunities for improvement. This module evaluation and reform generated opportunities for community partners to influence decisions in medical education and led to a collaborative evolution of a community-centred learning experience. Medical schools should actively engage community partners in teaching behavioural and social components of the curriculum and acknowledge their partners' expertise to promote community engagement and social accountability in medical education.

A4 A FRAMEWORK TO STUDY INFLAMMATORY BOWEL DISEASE AMONG INDIGENOUS PEOPLES AND PRELIMINARY RESULTS FROM SASKATCHEWAN, CANADA

Background

Inflammatory Bowel Disease (IBD) is a chronic condition with significant life-threatening disease-related complications and reductions in quality of life if left untreated. Despite available research about IBD in the general population, there is limited-to-no evidence about IBD among Indigenous peoples in Canada and around the world.

Aims

We aimed to define a collaborative framework, estimate the prevalence and incidence rates of IBD among First Nations in Saskatchewan, Canada, and explore perceptions of IBD among Indigenous peoples in the province.

Methods

This study began when Indigenous patients shared their health experiences with IBD with research team members. An interdisciplinary research team was formed including Indigenous patient and family advocates (IPFAs, Indigenous patients living with IBD and parents of an Indigenous person with IBD), an IBD gastroenterologist, knowledge users, and Indigenous and non-Indigenous researchers. Our research team committed to raise awareness of IBD among Indigenous peoples within Indigenous communities and among health care providers and to advocate for better healthcare and well-being by providing evidence of IBD among Indigenous peoples living with IBD in Saskatchewan. We defined a mixed methodology. The first phase of the study used Saskatchewan administrative health data to estimate the prevalence and incidence rates with 95% confidence intervals (95%CI) of IBD among First Nations. The second phase of the study will use a photovoice methodology to gather “the voices” of Indigenous peoples with IBD, encouraging self-interpretation of pictures, engaging their communities, and empowering them with the study findings.

Results

The IPFAs play a critical role in the project by sharing their experiences and defining the directions of the project, as well as defining our research framework (Figure 1). Preliminary results show that the prevalence of IBD among First Nations in Saskatchewan increased from 66 (95%CI 65–68) per 100,000 population in 1999 to 148 (95%CI 145–151) per 100,000 people in 2015. In contrast, the incidence rates appear to be stable over time, 11/100,000 (95%CI 4–24) in 1999 and 11/100,000 (95%CI 5–20) in 2015. We started recruiting participants for the photovoice study in September 2019.

Conclusions

This ground-breaking patient-driven study is the first stage to improve health among Indigenous peoples living with IBD in Saskatchewan. This project will generate community-engaged knowledge and expertise to inform the development of an Indigenous IBD framework that could promote better and knowledge-based healthcare for Indigenous peoples with IBD in Canada and worldwide.

Size Matters: Package Size Influences Recognition of Serving Size Information

PURPOSE

To identify the impact of package size on an individual's use of serving size information. The hypothesis was that participants would make more serving size assumption errors on a nutrition facts table (NFT) interpretation task when assessing packages that appear as a single serving but contain multiple servings, compared with products that appear as a multi-serving and contain multiple servings.

METHODS

Sixty participants were randomized into 1 of 3 conditions (n = 20 each); products that appeared as a single serving and contain a single serving (SSSS), products that appeared as a single serving and contain multiple servings (SSMS), and products that both appear as a multi-serving and contain multiple servings (MSMS). All 3 conditions were tested on a NFT interpretation task while participants were being presented food items that were appropriate to their given condition.

RESULTS

Participants in the SSMS (9.55 ± 7.78) condition made significantly more serving size assumption errors than the SSSS (0.00 ± 0.00; P < 0.001) and MSMS (0.40 ± 0.75; P < 0.001) conditions.

CONCLUSIONS

Participants did not address serving size information when they perceived a product to be a single serving. This resulted in people misinterpreting nutritional and caloric content of foods that were single unit foods with multiple servings.

Reduced prevalence of small-for-gestational-age and preterm birth for women of low socioeconomic position: a population-based cohort study comparing antenatal midwifery and physician models of care

OBJECTIVE

Our aim was to investigate if antenatal midwifery care was associated with lower odds of small-for-gestational-age (SGA) birth, preterm birth (PTB) or low birth weight (LBW) compared with general practitioner (GP) or obstetrician (OB) models of care for women of low socioeconomic position.

SETTING

This population-level, retrospective cohort study used province-wide maternity, medical billing and demographic data from British Columbia, Canada.

PARTICIPANTS

Our study included 57 872 pregnant women, with low socioeconomic position, who: were residents of British Columbia, Canada, carried a singleton fetus, had low to moderate medical/obstetric risk, delivered between 2005 and 2012 and received medical insurance premium assistance.

PRIMARY AND SECONDARY OUTCOME MEASURES

We report rates, adjusted ORs (aOR), and 95% CIs for the primary outcome, SGA birth (<the 10th percentile), and secondary outcomes, PTB (<37 weeks' completed gestation) and LBW (<2500 g).

RESULTS

Our sample included 4705 midwifery patients, 45 114 GP patients and 8053 OB patients. Odds of SGA birth were reduced for patients receiving antenatal midwifery versus GP (aOR 0.71, 95% CI 0.62 to 0.82) or OB care (aOR 0.59, 95% CI 0.50 to 0.69). Odds of PTB were lower for antenatal midwifery versus GP (aOR 0.74, 95% CI 0.63 to 0.86) or OB patients (aOR 0.53, 95% CI 0.45 to 0.62). Odds of LBW were reduced for midwifery versus GP (aOR 0.66, 95% CI 0.53 to 0.82) or OB patients (aOR 0.43, 95% CI 0.34 to 0.54).

CONCLUSION

Antenatal midwifery care in British Columbia, Canada, was associated with lower odds of SGA birth, PTB and LBW, for women of low socioeconomic position, compared with physician models of care. Results support the development of policy to ensure antenatal midwifery care is available and accessible for women of low socioeconomic position. Future research is needed to determine the underlying mechanisms linking midwifery care to better birth outcomes for women of low socioeconomic position.

Waiting for scheduled surgery: A complex patient experience

The aim of this study was to understand experiences of wait time among patients awaiting scheduled orthopaedic or cardiac surgery. Using a qualitative approach, 32 patients completed two interviews each regarding their wait time experiences, including effects of waiting. Patient experiences of wait time varied regardless of actual wait time and included reports of restriction, uncertainty, resignation, coping and opportunity. Participants' waiting experiences indicate a complex relationship between greater symptom severity and less tolerance for wait time. We suggest healthcare resources focus on alleviating the deleterious effects of waiting for certain patients rather than reducing absolute wait times.

Tricksterdom in narratives of young adult cancer: performances of uncertainty, subversion, and possibility

OBJECTIVE

As people with cancer attempt the difficult task of giving voice to life with illness, they often turn to mythic figures and stories (e.g., when people talk about battling cancer or embarking on a journey toward recovery). Little attention has been paid to the mythic figure of the trickster, recently identified by Arthur Frank (2009) as a prominent trope in some narrative accounts of illness. We investigated the prevalence of 3 tricksterly themes expressed within young adults' stories of cancer: destabilizing social or cosmic order (uncertainty), challenging dominant expectations for human life (subversion), and exploring alternative ways of viewing the world (possibility).

METHOD

We recruited 21 young adults with cancer from across Canada and conducted semistructured interviews. We then analyzed their stories using some elements of thematic, structural, and dialogical/performative narrative analysis-drawing attention to what was told and how/to whom were they told (Crossley, 2000; Frank, 2012; Riessman, 2008).

RESULTS

We describe each of the 3 themes in turn (i.e., uncertainty, subversion, and possibility) using excerpts from 6 interview transcripts, and show how they meaningfully converge into an interpretive framework of tricksterdom.

CONCLUSION

We conclude that the 3 themes of uncertainty, subversion, and possibility seem to come together as tricksterly performances, disrupting audiences' expectations of more typical forms of cancer narratives and calling attention to less familiar, structured, and "tellable" ways of narrating illness.

Cultural variations in developing a sense of knowing your own mind: A comparison between British and Japanese children

We often have a feeling that we know ourselves much better than others know us, coupled with a feeling that our minds are not transparent to other people. In this article we begin to explore cultural variations in the development of this feeling. Children in Britain and Japan aged 7, 9 and 11 years judged how well they and how well their parent/teacher knew about aspects of the child’s mind (e.g., dreams, feeling sick, feeling hungry). Compared with British children, Japanese children credited adults with relatively large amounts of knowledge about themselves and this was most notable in the youngest group. Differences in patterns of judgements between the two nations could arise from differences in the cultural influences on the rate of development.

Waiting for surgery from the patient perspective

The aim of this study was to perform a systematic review of the impact of waiting for elective surgery from the patient perspective, with a focus on maximum tolerance, quality of life, and the nature of the waiting experience. Searches were conducted using Medline, PubMed, CINAHL, EMBASE, and HealthSTAR. Twenty-seven original research articles were identified which included each of these three themes. The current literature suggested that first, patients tend to state longer wait times as unacceptable when they experienced severe symptoms or functional impairment. Second, the relationship between length of wait and health-related quality of life depended on the nature and severity of proposed surgical intervention at the time of booking. Third, the waiting experience was consistently described as stressful and anxiety provoking. While many patients expressed anger and frustration at communication within the system, the experience of waiting was not uniformly negative. Some patients experienced waiting as an opportunity to live full lives despite pain and disability. The relatively unexamined relationship between waiting, illness and patient experience of time represents an area for future research.
